Which two actions can be performed when an Autonomous Database is stopped? (Choose two.)
- A. Change administrator password
- B. Update License type
- C. Update Network Access
- D. Start
Answer: B,D
Explanation:
When an Autonomous Database is stopped, limited actions are available:
Correct Answer (B): Start is possible to bring the database back online via the OCI Console or API.
Correct Answer (C): Update License type (e.g., from License Included to Bring Your Own License) can be performed while stopped, as it's a configuration change not requiring database activity.
Incorrect Options:
A: Changing the admin password requires the database to be running for security validation.
D: Updating network access (e.g., ACLs) requires an active instance to apply changes.
These options reflect the stopped state's constraints.
NEW QUESTION # 55
Which two statements are true about the Oracle Cloud Infrastructure (OCI)? (Choose two.)
- A. A single fault domain can be associated with multiple regions and availability domains.
- B. Because availability domains do not share infrastructure such as power or cooling, or the internal availability domain network, a failure at one availability domain within a region is unlikely to impact the availability of the others within the same region.
- C. An OCI region is a localized geographic area, and an availability domain is one or more data centers located within a region.
- D. Regions are dependent on other regions and must be located within 5 thousand kilometers of each other.
Answer: B,C
Explanation:
Oracle Cloud Infrastructure (OCI) is designed with a hierarchical structure to ensure high availability and fault tolerance:
Correct Answer (B): "An OCI region is a localized geographic area, and an availability domain is one or more data centers located within a region" accurately describes OCI's architecture. A region is a standalone geographic area (e.g., US East), and availability domains (ADs) are isolated data centers within that region, enhancing resilience.
Correct Answer (D): "Because availability domains do not share infrastructure such as power or cooling, or the internal availability domain network, a failure at one availability domain within a region is unlikely to impact the availability of the others within the same region" reflects OCI's design for fault isolation. ADs are physically separate, minimizing the risk of cascading failures.
Incorrect Options:
A: Regions are independent, not dependent, and there's no 5,000-kilometer restriction; they are globally distributed for latency and redundancy purposes.
C: Fault domains are subdivisions within an AD, not across regions or ADs, ensuring resource isolation within a single AD.
This structure supports robust disaster recovery and high availability.
NEW QUESTION # 56
Which three options do NOT change when enabling auto scaling? (Choose three.)
- A. Number of OCPUs displayed in the console
- B. Parallelism settings
- C. Amount of storage
- D. I/O resources
- E. Level of concurrency
Answer: B,C,E
Explanation:
When enabling auto scaling in an Oracle Autonomous Database, the feature dynamically adjusts resources based on workload demand, but certain configuration elements remain unchanged unless manually altered.
Amount of storage (A): Auto scaling focuses on adjusting CPU and I/O resources to meet performance needs. The storage allocation remains constant because it is a separately provisioned resource that requires manual adjustment via the OCI Console or API. This ensures that storage capacity is not inadvertently reduced or expanded without explicit user intent.
Parallelism settings (B): These settings determine how many parallel processes are used for query execution. Auto scaling does not modify this pre-defined configuration; it adjusts resource usage (e.g., CPU cores) without altering the parallelism framework established for the database.
Level of concurrency (E): Concurrency refers to the maximum number of simultaneous user sessions. While auto scaling can indirectly influence concurrency by adjusting available resources, the concurrency limit itself is a fixed setting that remains unchanged unless explicitly modified by the administrator.
Incorrect Options:
I/O resources (C): Auto scaling directly impacts I/O resources by increasing or decreasing them alongside CPU adjustments to handle workload fluctuations.
Number of OCPUs displayed in the console (D): While the base OCPU count remains static, the effective number of OCPUs in use (up to three times the base) changes dynamically with auto scaling, and this is reflected in the console, making this option subject to change.
This behavior ensures that auto scaling optimizes performance without disrupting foundational database configurations.
NEW QUESTION # 57
Which statement is true about OCPUs and storage when you choose to scale your Autonomous Database?
- A. OCPUs and storage must remain in sync
- B. OCPUs and storage can be scaled independently
- C. Use auto scaling to increase storage
- D. Increasing OCPUs will automatically increase storage
Answer: B
Explanation:
Scaling resources in Autonomous Database offers flexibility. The true statement is:
OCPUs and storage can be scaled independently (A): In Autonomous Database, you can adjust the number of OCPUs (compute resources) and storage capacity (in terabytes) separately via the OCI console or CLI. For example, you might provision an ADB with 2 OCPUs and 1 TB of storage. Later, you could scale to 4 OCPUs without changing storage, or increase storage to 2 TB without touching OCPUs. This decoupling allows tailored resource allocation-e.g., more compute for a CPU-intensive workload or more storage for growing data-without over-provisioning. Scaling is online, with no downtime, and status shows "SCALING IN PROGRESS" during the operation.
The incorrect options are:
Use auto scaling to increase storage (B): Auto scaling applies to OCPUs only, allowing up to 3x the base CPU allocation dynamically. Storage scaling is manual; you specify a new size (e.g., via oci db autonomous-database update), not via auto scaling.
Increasing OCPUs will automatically increase storage (C): There's no automatic linkage between OCPU and storage scaling. They are independent parameters, and increasing one does not affect the other unless explicitly requested.
OCPUs and storage must remain in sync (D): No such synchronization is required. You can have 1 OCPU with 10 TB or 10 OCPUs with 1 TB, depending on workload needs.
This independence is a hallmark of Autonomous Database's elasticity.
NEW QUESTION # 58
Which are two available options when creating an Autonomous Database? (Choose two.)
- A. APEX Service on Shared Infrastructure
- B. Autonomous JSON Database on Shared Infrastructure
- C. Autonomous JSON Database on Dedicated Infrastructure
- D. APEX Service on Dedicated Infrastructure
Answer: B,D
Explanation:
Creating an Autonomous Database offers specific deployment options. The two correct ones are:
APEX Service on Dedicated Infrastructure (A): This option provisions an Autonomous Database on dedicated Exadata infrastructure with Oracle Application Express (APEX) pre-installed and optimized. It's ideal for APEX-based apps (e.g., custom web forms) requiring isolated resources. In the OCI console, you select "Dedicated Infrastructure" and "APEX Service" as the workload type, specifying OCPUs and storage. For example, a company might deploy an APEX app for internal reporting on a dedicated ACD, ensuring performance isolation from other tenants.
Autonomous JSON Database on Shared Infrastructure (C): This creates a schema-less, JSON-centric ADB on shared infrastructure, optimized for document storage (e.g., { "order_id": 123, "items": [...] }). It's provisioned via the OCI console under "Shared Infrastructure," selecting "JSON Database" as the workload type. For instance, a mobile app might use it to store user data, leveraging SQL/JSON queries like SELECT JSON_VALUE(doc, '$.order_id'). It's cost-effective and fully managed, sharing Exadata resources.
The incorrect options are:
APEX Service on Shared Infrastructure (B): There's no distinct "APEX Service" workload type on shared infrastructure. APEX is available within ATP or ADW on shared infra, but it's not a standalone option-you'd provision ATP and enable APEX manually, not as a dedicated "APEX Service." Autonomous JSON Database on Dedicated Infrastructure (D): JSON Database is only offered on shared infrastructure, not dedicated. Dedicated options include ATP, ADW, and APEX Service, but JSON Database leverages shared resources for simplicity and cost.
These options cater to specific app development (APEX) and NoSQL (JSON) needs.
NEW QUESTION # 59
Which three Oracle Cloud Infrastructure (OCI) resources do you need to configure before provisioning your Autonomous Database with a private endpoint? (Choose three.)
- A. Route Table
- B. Network Security Group
- C. Subnet
- D. VCN
- E. Security List
Answer: B,C,D
Explanation:
Provisioning an Autonomous Database with a private endpoint requires:
Correct Answer (A): Network Security Group (NSG) defines traffic rules for the private endpoint, restricting access to specific sources.
Correct Answer (B): VCN (Virtual Cloud Network) provides the network foundation, hosting the subnet and endpoint.
Correct Answer (E): Subnet (private) contains the database's private endpoint, isolating it from public access.
Incorrect Options:
C: Security Lists apply to subnets but are optional with NSGs, which are preferred for finer control.
D: Route Table is needed for connectivity (e.g., to a NAT Gateway), but not strictly required for the private endpoint itself.
These ensure secure, private access.
NEW QUESTION # 60
What are two differentiators of Oracle Autonomous Database on Dedicated Infrastructure? (Choose two.)
- A. Users are offered greater control and isolation starting at the Exadata Cloud Infrastructure level.
- B. Users have OS access to the database machine.
- C. Users have SYS privileges in the database.
- D. Users have more control over the maintenance schedule.
- E. Users can customize the OS stack and add additional packages.
Answer: A,D
Explanation:
Autonomous Database on Dedicated Infrastructure offers unique features:
Correct Answer (A): "Users are offered greater control and isolation starting at the Exadata Cloud Infrastructure level" highlights dedicated hardware (compute, storage, network), ensuring isolation and performance not available in shared setups.
Correct Answer (E): "Users have more control over the maintenance schedule" allows scheduling maintenance windows, unlike shared infrastructure's fixed schedules.
Incorrect Options:
B: OS customization is not allowed; Oracle manages the stack fully.
C: No OS access is provided; it's a managed service.
D: SYS privileges are not unique to dedicated infrastructure; they depend on user roles, not deployment type.
These differentiators enhance control and isolation for enterprise needs.
NEW QUESTION # 61
You want to enable automatic indexing in a database, but any new auto indexes should be created as invisible indexes, so that they cannot be used in SQL statements. Which command will you use?
- A. EXEC DBMS_AUTO_INDEX.CONFIGURE('AUTO_INDEX_MODE','INVISIBLE')
- B. EXEC DBMS_AUTO_INDEX.CONFIGURE('AUTO_INDEX_MODE','IMPLEMENT')
- C. EXEC DBMS_AUTO_INDEX.CONFIGURE('AUTO_INDEX_MODE','OFF')
- D. EXEC DBMS_AUTO_INDEX.CONFIGURE('AUTO_INDEX_MODE','REPORT ONLY')
Answer: D
Explanation:
Oracle's automatic indexing feature, available in Autonomous Database, optimizes query performance by creating and managing indexes. The requirement here is to enable it but ensure new indexes are invisible (not used by the optimizer unless explicitly made visible). The correct command is:
EXEC DBMS_AUTO_INDEX.CONFIGURE('AUTO_INDEX_MODE','REPORT ONLY') (C): The REPORT ONLY mode enables automatic indexing, where the database identifies and creates candidate indexes based on workload analysis. However, these indexes are created as invisible by default, meaning the optimizer does not use them in SQL execution plans unless a DBA manually makes them visible (e.g., via ALTER INDEX ... VISIBLE). This mode is ideal for testing or validation without impacting production queries. For example, if a query frequently filters on a column, an invisible index might be created, but it won't affect performance until explicitly activated.
The incorrect options are:
EXEC DBMS_AUTO_INDEX.CONFIGURE('AUTO_INDEX_MODE','IMPLEMENT') (A): The IMPLEMENT mode fully enables automatic indexing, creating and maintaining visible indexes that the optimizer uses immediately. This contradicts the requirement for invisible indexes.
EXEC DBMS_AUTO_INDEX.CONFIGURE('AUTO_INDEX_MODE','OFF') (B): The OFF mode disables automatic indexing entirely, so no indexes (visible or invisible) are created, failing the requirement to enable it.
EXEC DBMS_AUTO_INDEX.CONFIGURE('AUTO_INDEX_MODE','INVISIBLE') (D): There is no INVISIBLE mode in DBMS_AUTO_INDEX.CONFIGURE. While indexes can be set as invisible individually, this is not a valid configuration option for the auto-indexing feature.
The REPORT ONLY mode provides a controlled approach, allowing index creation for analysis without immediate deployment. This is particularly useful in Autonomous Database, where automation is balanced with DBA oversight.
NEW QUESTION # 62
For fleet admins to access dedicated Exadata infrastructure, which policy should be assigned?
- A. Allow group adb-admins to manage autonomous-database in tenancy where target.workloadType='DW'
- B. Allow group adb-admins to manage autonomous-database in tenancy where target.workloadType='OLTP'
- C. Allow group adb-admins to manage autonomous-database-family in tenancy
- D. Allow group adb-admins to manage autonomous-database in tenancy
Answer: C
Explanation:
Fleet administrators managing dedicated Exadata infrastructure in Oracle Autonomous Database require broad permissions across all Autonomous Database resources, including those on dedicated infrastructure.
Correct Answer (B): The policy Allow group adb-admins to manage autonomous-database-family in tenancy grants comprehensive management rights over the entire Autonomous Database family, including dedicated Exadata infrastructure. The autonomous-database-family resource type encompasses all Autonomous Database resources (shared and dedicated) within the tenancy, making it suitable for fleet admins.
Incorrect Options:
A: Limits permissions to databases with the OLTP workload type (Autonomous Transaction Processing), excluding Data Warehouse (DW) or other types on dedicated infrastructure.
C: Restricts access to DW workload types only, omitting OLTP and other configurations.
D: Grants permissions only to autonomous-database resources, which may not fully cover dedicated infrastructure components like Autonomous Container Databases or Exadata Infrastructure.
This policy ensures fleet admins have the necessary scope to manage all aspects of dedicated deployments.

Given the steps:
Create Oracle Machine Learning User
Create Projects
Create Workspaces
Create Notebooks
Run SQL Scripts
Which two steps are out of order when working with Oracle Machine Learning?
- A. Create Projects
- B. Create Notebooks
- C. Create Workspaces
- D. Create Oracle Machine Learning User
- E. Run SQL Scripts
Answer: A,C
Explanation:
Full Detailed In-Depth Explanation:
The correct sequence for Oracle Machine Learning (OML) is:
Create Oracle Machine Learning User: First step to enable OML access.
Create Workspaces: Containers for organizing projects.
Create Projects: Groups for related notebooks within a workspace.
Create Notebooks: Environments for coding and analysis.
Run SQL Scripts: Executed within notebooks.
In the given list, Create Projects (2) comes before Create Workspaces (3), which is reversed. Workspaces must exist before projects. Thus, C and D are out of order.
NEW QUESTION # 64
How can you keep Autonomous Database tables in sync with an on-premises data source?
- A. Use the ORDS package on the Data Load page
- B. Use the Link Data option on the Data Load page
- C. Use the FEED DATA option on the Data Load page
- D. Use the Cloud Locations card on the Data Load page
Answer: D
Explanation:
Keeping Autonomous Database tables synchronized with an on-premises data source involves loading and updating data from external locations. The Cloud Locations card on the Data Load page is the correct method:
Correct Answer (B): The Cloud Locations card allows users to connect to Oracle Cloud Infrastructure (OCI) Object Storage buckets and load data into Autonomous Database tables. By regularly updating the data in Object Storage from the on-premises source (e.g., via scripts or tools), you can maintain synchronization using this feature. It supports automated data loading workflows when paired with appropriate processes.
Incorrect Options:
A: Oracle REST Data Services (ORDS) is used for building RESTful web services, not for direct data synchronization from on-premises sources to Autonomous Database tables.
C: The Link Data option enables linking to external database tables (e.g., via database links), but it doesn't inherently synchronize data; it provides access rather than replication.
D: There is no "FEED DATA" option on the Data Load page in Autonomous Database; this appears to be a fabricated choice.
This method leverages OCI Object Storage as an intermediary, making it a practical solution for ongoing synchronization.
NEW QUESTION # 65
Which Autonomous Database Cloud Service ignores hints in SQL statements by default?
- A. Neither service ignores hints by default
- B. Both services ignore hints by default
- C. Autonomous Data Warehouse
- D. Autonomous Transaction Processing
Answer: C
Explanation:
Full Detailed In-Depth Explanation:
Oracle Autonomous Database offers two primary services: Autonomous Data Warehouse (ADW) and Autonomous Transaction Processing (ATP), each optimized for different workloads. SQL hints are directives embedded in SQL statements to influence the optimizer's execution plan. However, their handling differs between the services:
Autonomous Data Warehouse (ADW): ADW is designed for analytical workloads and data warehousing, where query performance is critical. To ensure optimal execution, ADW's optimizer relies heavily on its own statistics and algorithms, ignoring SQL hints by default. This behavior prevents user-provided hints from overriding the automated optimization strategies tailored for complex analytical queries.
Autonomous Transaction Processing (ATP): ATP targets transactional workloads (OLTP) and provides more flexibility. It does not ignore hints by default, allowing developers and DBAs to use hints to fine-tune query execution plans for specific transactional needs.
Thus, only ADW ignores hints by default, making option C the correct answer. Options A and B are incorrect because ATP does not share ADW's default behavior, and option D incorrectly identifies ATP as the service that ignores hints.
NEW QUESTION # 66
In the Autonomous Database on Dedicated Infrastructure service, what does the fleet administrator use to control OCPU utilization?
- A. Oracle Machine Learning notebook
- B. Resource Manager settings
- C. SQL Developer Web Console
- D. Compartment quotas
Answer: D
Explanation:
Fleet administrators manage resource utilization in Autonomous Database on Dedicated Infrastructure:
Correct Answer (B): Compartment quotas are used to set limits on OCPU usage across multiple database instances within a compartment. This OCI feature allows administrators to define maximum resource allocations, ensuring efficient use and cost control at a tenancy level.
Incorrect Options:
A: Oracle Machine Learning notebooks are for analytics, not resource control.
C: SQL Developer Web Console manages individual database tasks, not fleet-wide OCPU limits.
D: Resource Manager settings apply to individual instances, not fleet-level quotas.
Compartments provide a scalable, tenancy-wide control mechanism.
NEW QUESTION # 67
Which two statements are true about using an Oracle Autonomous Database with private endpoints? (Choose two.)
- A. A Network Security Group is required within your Virtual Cloud Network before you can provision a shared Autonomous Database to use private endpoints.
- B. You can configure private endpoints for an Always Free Autonomous Database
- C. An Autonomous Database with private endpoints can be accessed from the public internet by adding your IP address to an Access Control List (ACL).
- D. Private endpoints can be configured when you clone a shared Autonomous Database that was initially created with public endpoints.
Answer: A,D
Explanation:
Private endpoints enhance security for Autonomous Database:
Correct Answer (A): "A Network Security Group is required within your Virtual Cloud Network before you can provision a shared Autonomous Database to use private endpoints" is true. An NSG is mandatory to define ingress/egress rules for the private subnet hosting the endpoint.
Correct Answer (C): "Private endpoints can be configured when you clone a shared Autonomous Database that was initially created with public endpoints" is true. Cloning allows switching to a private endpoint configuration.
Incorrect Options:
B: Private endpoints are inaccessible from the public internet, even with ACLs; that's their purpose.
D: Always Free tier doesn't support private endpoints; it's limited to public access.
This ensures isolated, secure connectivity.
NEW QUESTION # 68
Which two infrastructure types support deployment of Oracle Autonomous Database? (Choose two.)
- A. Dedicated Exadata Infrastructure
- B. Shared Exadata Infrastructure
- C. Virtual Machines on Oracle Cloud Infrastructure
- D. Oracle Bare Metal Servers
Answer: A,B
Explanation:
Oracle Autonomous Database is designed to run on specific infrastructure optimized for its managed capabilities:
Correct Answer (B): Dedicated Exadata Infrastructure provides a fully dedicated Exadata system for a single tenant, offering maximum isolation, performance, and customization (e.g., maintenance scheduling).
Correct Answer (D): Shared Exadata Infrastructure allows multiple Autonomous Database instances to share Exadata resources, providing a cost-effective option for smaller workloads while retaining automation benefits.
Incorrect Options:
A: Virtual Machines (VMs) on OCI are not a supported deployment platform for Autonomous Database. It requires Exadata hardware for its self-managing features, unlike traditional OCI VMs used for manual database setups.
C: Oracle Bare Metal Servers are not used for Autonomous Database; they lack the specialized Exadata architecture needed for its autonomous operations.
These infrastructure types ensure high performance and scalability tailored to Autonomous Database's requirements.
NEW QUESTION # 69
Which two statements apply to the Autonomous Database service on Dedicated Infrastructure? (Choose two.)
- A. You, as the customer, are responsible for all patching operations
- B. You can set maintenance windows for each individual Autonomous Container Database
- C. Patching occurs on the first Sunday of each quarter
- D. You can set maintenance windows for an Autonomous Exadata Infrastructure
Answer: A,B
Explanation:
Autonomous Database on Dedicated Infrastructure offers more control than shared infrastructure. The two correct statements are:
You, as the customer, are responsible for all patching operations (A): In dedicated infrastructure, customers manage patching for Autonomous Container Databases (ACDs) and Autonomous Databases (ADBs), unlike shared infrastructure where Oracle handles it. You choose when to apply Release Updates (RUs) or skip them (up to two quarters), using the OCI console or API (e.g., oci db autonomous-container-database update). For example, you might schedule an RU for an ACD on a Saturday night, downloading the patch from Oracle and applying it manually to minimize downtime. This responsibility comes with the dedicated model's flexibility.
You can set maintenance windows for each individual Autonomous Container Database (C): Dedicated infrastructure allows setting specific maintenance windows per ACD, not just at the Exadata Infrastructure level. In the OCI console, under each ACD's details, you configure a preferred time (e.g., "Sundays, 02:00-04:00 UTC"), ensuring patches or upgrades align with your schedule. For instance, ACD1 might patch Sundays, while ACD2 patches Tuesdays, tailoring downtime to different workloads.
The incorrect options are:
You can set maintenance windows for an Autonomous Exadata Infrastructure (B): Maintenance windows are set at the ACD level, not the broader Autonomous Exadata Infrastructure (AEI) level. AEI maintenance (e.g., hardware updates) is Oracle-managed, with notification but no customer scheduling.
Patching occurs on the first Sunday of each quarter (D): There's no fixed schedule like "first Sunday." In dedicated mode, you control patching timing within a quarter, notified by Oracle of available RUs, unlike shared infrastructure's Oracle-driven schedule.
These statements highlight dedicated infrastructure's customer-driven management.
NEW QUESTION # 70
Your company has a .NET application and wants to deploy it on Autonomous Database (ADB). What software is used to connect to ADB from the .NET application?
- A. Oracle Data Access Components for Windows
- B. You cannot use .NET with ADB
- C. Java
- D. SQL*Plus
Answer: A
Explanation:
Connecting a .NET application to Autonomous Database (ADB) requires a specific client library compatible with Oracle's database connectivity standards. The correct software is:
Oracle Data Access Components for Windows (D): Oracle Data Access Components (ODAC) for Windows is the recommended software for .NET applications to connect to ADB. ODAC includes the Oracle Data Provider for .NET (ODP.NET), which supports ADO.NET interfaces for database access. It enables .NET developers to use familiar APIs (e.g., OracleConnection, OracleCommand) to interact with ADB over Oracle Net Services, leveraging the secure TLS connection required by ADB (via the client wallet). For example, a .NET app might use ODAC to execute SELECT * FROM customers against an ADB instance, authenticating with a wallet downloaded from the OCI console. ODAC supports both managed and unmanaged modes: the managed ODP.NET is lightweight and assembly-based, while the unmanaged version integrates with Oracle Client libraries. To set it up, developers install ODAC (e.g., via NuGet or Oracle's download site), configure the wallet (e.g., tnsnames.ora), and write code like:
csharp
CollapseWrapCopy
using Oracle.ManagedDataAccess.Client;
string connString = "User Id=USER1;Password=pwd;Data Source=adb_high";
using (OracleConnection conn = new OracleConnection(connString)) {
conn.Open();
// Query execution here
}
This ensures seamless integration with ADB's managed environment, supporting features like connection pooling and high performance.
The incorrect options are:
SQL*Plus (A): SQL*Plus is a command-line tool for SQL execution and administration, not a programmatic library for .NET applications. It's unsuitable for embedding in a .NET app, as it lacks API integration and is meant for manual use (e.g., running scripts like SELECT * FROM table;).
You cannot use .NET with ADB (B): This is false. .NET is fully supported via ODAC, allowing applications (e.g., ASP.NET web apps or Windows services) to connect to ADB just like any Oracle database, provided the wallet and credentials are configured.
Java (C): Java uses JDBC (e.g., Oracle JDBC Driver) for database connectivity, not .NET. While JDBC works with ADB for Java apps, it's irrelevant for a .NET environment, where ODAC is the standard.
ODAC's robust support for .NET makes it the definitive choice, bridging Microsoft's ecosystem with Oracle's cloud database.
NEW QUESTION # 71
Which three tools can be used to monitor the usage and activities of Autonomous Database on Dedicated Infrastructure? (Choose three.)
- A. Performance Hub
- B. RMAN
- C. OCI Metrics
- D. Enterprise Manager Cloud Control
- E. Logs
Answer: A,C,D
Explanation:
Monitoring Autonomous Database on Dedicated Infrastructure involves specific tools:
Correct Answer (C): Enterprise Manager Cloud Control provides comprehensive monitoring of OCI resources, including CPU, memory, I/O, and SQL performance for dedicated deployments.
Correct Answer (D): OCI Metrics offers detailed metrics via the OCI Monitoring service, allowing custom dashboards and alerts for key performance indicators (e.g., OCPU usage, storage).
Correct Answer (E): Performance Hub is a built-in tool in Autonomous Database for analyzing historical performance data, identifying trends, and troubleshooting issues.
Incorrect Options:
A: RMAN (Recovery Manager) is for backup and recovery, not real-time monitoring of usage or activities.
B: Logs provide diagnostic data but are not a standalone monitoring tool; they require manual analysis or integration with other tools.
These tools collectively enable proactive management and optimization.
NEW QUESTION # 72
What happens with the standby database when disabling Autonomous Data Guard?
- A. The standby database is started read-only
- B. The standby database is transformed into a refreshable clone
- C. The standby database is terminated.
- D. The standby database is started read-write
Answer: C
Explanation:
Disabling Autonomous Data Guard affects the standby database:
Correct Answer (A): "The standby database is terminated" is true. When Data Guard is disabled via the OCI Console or API, the standby database is deleted, ending its role as a replica. This is a permanent action requiring re-enablement to recreate a standby.
Incorrect Options:
B: The standby doesn't become read-write; it's removed entirely.
C: It doesn't remain read-only; termination stops all operations.
D: It's not converted to a refreshable clone; that's a separate feature.
This ensures resource cleanup when high availability is no longer needed.
NEW QUESTION # 73
Which is an Autonomous Database critical event?
- A. Admin Password Warning
- B. Database Connection
- C. New Maintenance Schedule
- D. Maintenance Begin
- E. Schedule Maintenance Warning
Answer: A
Explanation:
Critical events in Autonomous Database are those requiring immediate attention due to potential security or operational impacts:
Correct Answer (D): "Admin Password Warning" is a critical event because it indicates the admin password is nearing expiration (typically within 7 days). If not updated, it could lock out administrative access, posing a security and availability risk.
Incorrect Options:
A: "Maintenance Begin" is an operational event, not critical, as it's planned and managed by Oracle.
B: "Database Connection" is a routine activity, not an event requiring urgent action.
C: "Schedule Maintenance Warning" is informational, not critical, as it's a precursor to planned maintenance.
E: "New Maintenance Schedule" is administrative, not an immediate threat.
This ensures timely response to security-critical situations.
NEW QUESTION # 74
Which tab in the Data Load Explore tool shows the size of the table and the number of rows and columns?
- A. Hierarchies tab
- B. Measures tab
- C. Data Sources tab
- D. Statistics tab
Answer: D
Explanation:
The Data Load Explore tool in Autonomous Database helps users analyze loaded data. The correct tab is:
Statistics tab (B): The Statistics tab displays detailed metadata about a table, including its size (e.g., in MB or GB), number of rows, and number of columns. For example, after loading a CSV into a table SALES, this tab might show "Rows: 10,000, Columns: 5, Size: 2.3 MB," providing a quick overview of the dataset's scale and structure. It's designed for understanding data volume and composition, aiding decisions like partitioning or indexing.
The incorrect options are:
Hierarchies tab (A): This tab shows hierarchical relationships in the data (e.g., parent-child links), not basic table metrics like size or row count. It's more about data organization than statistics.
Data Sources tab (C): This tab lists the sources of loaded data (e.g., OCI Object Storage buckets or files), not the resulting table's properties. It focuses on origin, not metrics.
Measures tab (D): The Measures tab defines numerical aggregates (e.g., sum of sales), used for analytics, not raw table statistics like row or column counts.
The Statistics tab is the go-to for table sizing details in Data Load Explore.
