NEW QUESTION # 15
What components are required for setting up an Azure VNet to Oracle Cloud Infrastructure VCN connection as part of the OCI-Azure Interconnect?
- A. An Azure VNet with subnets and a virtual network gateway, and an OCI VCN with subnets and an attached service gateway
- B. An Azure VNet with subnets and a virtual network gateway, and an OCI VCN with subnets and an attached dynamic routing gateway
- C. An Azure VNet with subnets and a virtual network gateway, and an OCI VCN with subnets and an attached NAT gateway
- D. An Azure VNet with subnets and a virtual network gateway, and an OCI VCN with subnets and an attached internet gateway
Answer: B
Explanation:
If you closely look at the options, you can start eliminating some of them.
We can easily eliminate "An Azure VNet with subnets and a virtual network gateway, and an OCI VCN with subnets and an attached service gateway" as we don't require service gateway to setup OCI-Azure Interconnect.
On similar lines, we can also eliminate the options where internet gateway and NAT gateway is pre-sent.
Hence "An Azure VNet with subnets and a virtual network gateway, and an OCI VCN with sub-nets and an attached internet gateway" and "An Azure VNet with subnets and a virtual network gateway, and an OCI VCN with subnets and an attached NAT gateway".
As you can see in the architecture below, on the OCI side you require a Dynamic Routing Gate-way and on the Azure side you need a Virtual Network Gateway.
Hence the option "An Azure VNet with subnets and a virtual network gateway, and an OCI VCN with subnets and an attached dynamic routing gateway" is CORRECT.
NEW QUESTION # 16
An organization wants to deploy Oracle Database Service for Azure in the existing Oracle Cloud Infrastructure and Azure tenancies that are in the supported regions. However, they want to have full control over the Azure permissions that should be granted.
Which option should they choose during the sign-up process?
- A. Fully scripted configuration
- B. Fully automated configuration
- C. Guided account linking
- D. Auto pilot linking
Answer: C
Explanation:
The keyword mentioned in the question is "However, they want to have full control over the Az-ure permissions that should be granted. " The fully-automated onboarding option for OracleDB for Azure is faster and more convenient than the guided account linking, but some organizations may have security policies that do not allow them to grant the required permissions to the Oracle Database Service enterprise applica-tion that runs in their Azure account.
Guided onboarding is provided for customers who do not want to grant OracleDB for Azure all the Azure permissions required for fully automated onboarding.
The remaining two options - Auto pilot linking and Fully scripted configuration are INVALID. There doesn't exist anything like these in Oracle Database Service for Azure onboarding.
Hence the correct answer is Guided account linking
NEW QUESTION # 17

- C. Autonomous Database on Dedicated Infrastructure
- D. Autonomous Database on Shared Infrastructure
Answer: B
Explanation:
As you can see in the screenshot, Exadata Database Service on Shared Infrastructure is NOT sup-ported.
NEW QUESTION # 18
Which components are required to establish a Site-to-Site VPN connection in Oracle Cloud Infra-structure?
- A. Internet Gateway (IG), Network Address Translation (NAT) Gateway, and IPsec tun-nel
- B. Dynamic Routing Gateway (DRG), NAT Gateway, and IPsec tunnel
- C. Internet Gateway, Customer Premises Equipment (CPE), and IPsec tunnel
- D. Dynamic Routing Gateway (DRG), Customer Premises Equipment (CPE), and IPsec tunnel
Answer: D
Explanation:
Site-to-Site VPN Components:
CPE OBJECT: At your end of Site-to-Site VPN is the actual device in your on-premises network (whether hardware or software). The term customer-premises equipment (CPE) is commonly used in some industries to refer to this type of on-premises equipment.
DYNAMIC ROUTING GATEWAY (DRG): At Oracle's end of Site-to-Site VPN is a virtual router called a dynamic routing gateway, which is the gateway into your VCN from your on-premises network.
IPSEC CONNECTION: After creating the CPE object and DRG, you connect them by creating an IPSec connection, which you can think of as a parent object that represents the Site-to-Site VPN.
TUNNEL: An IPSec tunnel is used to encrypt traffic between secure IPSec endpoints. Oracle cre-ates two tunnels in each IPSec connection for redundancy.
So, Internet Gateway, NAT Gateway are NOT valid Site-to-Site VPN Components.
Hence, Dynamic Routing Gateway (DRG), Customer Premises Equipment (CPE), and IPsec tunnel is the CORRECT answer.
NEW QUESTION # 19
What is the primary difference between using Oracle FastConnect with an Oracle partner and using FastConnect with colocation with Oracle?
- A. The method of establishing the physical connection to Oracle Cloud Infrastructure
- B. The geographical locations available for connections
- C. The type of virtual circuits supported
- D. The number of available redundancy models
Answer: A
Explanation:
FastConnect: With an Oracle Partner:
You can establish a FastConnect connection from your on-premise or remote data center to the data center where your Oracle Cloud resources are provisioned by requesting cloud connectivity services from any of Oracle's FastConnect partners. Oracle has integrated the FastConnect service with a geographically diverse set of IP, VPN, and Ethernet network providers and cloud exchanges to make it easy for you to establish a connection to Oracle Cloud services.
FastConnect: Colocation with Oracle:
If you have purchased colocation space from a data center provider, you can use Oracle FastCon-nect to establish connectivity from your network equipment in that colocation facility to your Oracle Cloud services provisioned at this location. Oracle will provide you a letter of authorization (LOA) that the data center provider will need in order to establish a direct cross-connect into Oracle's FastConnect edge devices provider will need in order to establish a direct cross
NEW QUESTION # 20
A company has deployed an application in Oracle Cloud Infrastructure consisting of multiple web servers, database servers, and application servers. The company wants to restrict communication be-tween these components, allowing only the necessary traffic between them. Which OCI feature would be most suitable to achieve this objective?
- A. Use Network Security Groups to apply specific firewall rules for each component.
- B. Use Route Tables to define custom routing policies between each component.
- C. Use Virtual Cloud Networks to create isolated networks for each component.
- D. Use Security Lists to configure network access rules for the entire Virtual Cloud Net-work.
Answer: A
Explanation:
Network security groups (NSGs) act as a virtual firewall for your compute instances .
An NSG consists of a set of ingress and egress security rules that apply only to a set of VNICs of your choice in a single VCN (for example: all the compute instances that act as web servers in the web tier of a multi-tier application in your VCN).
Hence, "Use Network Security Groups to apply specific firewall rules for each component." is the CORRECT answer.
In this question , you can straightaway reject "Use Virtual Cloud Networks to create isolated net-works for each component." and "Use Route Tables to define custom routing policies between each component." options.
NSG wins here due to the keywords "restrict communication between these components" in the question. A network security group (NSG) provides a virtual firewall for a set of cloud re-sources that all have the same security posture.
NEW QUESTION # 21
What is the purpose of using Oracle Cloud Infrastructure (OCI) Identity and Access Management (IAM) policies in a cross-cloud connection between Microsoft Azure and OCI?
- A. To control the bandwidth of the connection between the Azure VNet and the OCI VCN
- B. To control the type of traffic allowed between the Azure VNet and the OCI VCN
- C. To control the location of the cross-cloud connection
- D. To control who can manage OCI route tables, network security groups, and security lists
Answer: D
Explanation:
Controlling the Establishment of a Connection
With Oracle Cloud Infrastructure IAM policies, you can control:
Who in your organization has the authority to create a FastConnect virtual circuit.
Who can manage route tables, network security groups, and security lists.
Oracle and Microsoft have created a cross-cloud connection between Oracle Cloud Infrastructure and Microsoft Azure in certain regions. So, the option "To control the location of the cross-cloud connection" has nothing to do with IAM policies and hence is INCORRECT.
The option "To control the type of traffic allowed between the Azure VNet and the OCI VCN" is also INCORRECT as you use Security Lists/Network Security Group to filter traffic and not IAM policies.
IAM policies also have no role to play in determining the bandwidth of the connection.
NEW QUESTION # 22
A company wants to seamlessly build a private interconnection between their OCI and Microsoft Azure environments with consistent performance and low latency. They want to enable their cloud engineers to set up Single Sign-On (SSO) between Microsoft Azure and OCI for their Oracle appli-cations, such as PeopleSoft, JD Edwards EnterpriseOne, and E-Business Suite.
Which technology integration can the company use to achieve this goal?
- A. Direct Connect and Azure VPN Gateway
- B. OCI Site-to-Site VPN and Azure Site-to-Site VPN
- C. Cloud Interconnect and Virtual WAN
- D. Oracle FastConnect and Azure ExpressRoute
Answer: D
Explanation:
By using Oracle FastConnect and Azure ExpressRoute, customers can seamlessly build a private interconnection between their OCI and Microsoft Azure environments. The Interconnect also ena-bles joint customers to take advantage of a unified identity and access management platform that leads to cost savings. Cloud engineers can set up SSO between Microsoft Azure and OCI for their Oracle applications, such as PeopleSoft, JD Edwards EnterpriseOne, and E-Business Suite. Having a federated SSO makes the integration seamless and allows users to authenticate only once to access multiple applications, without signing in separately to access each application.

- A. Key Vault Administrator, Log Analytics Contributor, or Security Manager
- B. Network Contributor, Security Reader, User Access Administrator, or Virtual Machine Contributor
- C. Resource Group Contributor, Subscription Contributor, Backup Contributor, or Stor-age Account Contributor
- D. Application Administrator, Cloud Application Administrator, Privileged Role Adminis-trator, or Global Administrator
Answer: D
Explanation:
The automated onboarding process requires that the Azure user onboarding to OracleDB for Az-ure have at least one of the following admin roles:
Application Administrator, Cloud Application Administrator, Privileged Role Administrator, or Global Administrator.
NEW QUESTION # 24
Which is NOT an Azure resource that is created when you provision a database using Oracle Data-base Service for Azure?
- A. Log Analytics workspace
- B. Custom Dashboard workspace
- C. Application Insights workspace
- D. Oracle Database Service
Answer: D
Explanation:
Log Analytics Workspace, Application Insights and Custom Dashboard are Azure resources and hence we can eliminate these options.
We are left with Oracle Database Service which is the CORRECT answer.
NEW QUESTION # 25
What encryption protocol is used to secure data transmission in an OCI Site-to-Site VPN connec-tion?
- A. Internet Protocol Security (IPSec)
- B. Secure Sockets Layer (SSL)
- C. Datagram Transport Layer Security (DTLS)
- D. Transport Layer Security (TLS)
Answer: A
Explanation:
Site-to-Site VPN provides a site-to-site IPSec connection between your on-premises network and your virtual cloud network (VCN). The IPSec protocol suite encrypts IP traffic before the packets are transferred from the source to the destination and decrypts the traffic when it arrives.
NEW QUESTION # 26
An enterprise has a workload running in a VNet in Microsoft Azure and a database running in a VCN in Oracle Cloud Infrastructure. The enterprise wants to set up a private, secure, and isolated network connection between the two clouds to enable traffic flow between the workload and the database. Which option can be used to achieve this requirement?
- A. Use Azure VPN and Oracle FastConnect to establish a private and secure tunnel be-tween the Azure VNet and the OCI VCN.
- B. Use Azure ExpressRoute and Oracle FastConnect to create a private interconnection between the Azure VNet and the OCI VCN.
- C. Use Azure Private Link to create a private connection between the workload and the database.
- D. Use public internet to establish connectivity between the Microsoft Azure VNet and the OCI VCN.
Answer: B
Explanation:
As per the question, the keywords are "The enterprise wants to set up a private, secure, and isolat-ed network connection between the two clouds" Use public internet to establish connectivity between the Microsoft Azure VNet and the OCI VCN - INCORRECT as this option won't provide private, secure and isolated connection.
Use Azure VPN and Oracle FastConnect to establish a private and secure tunnel between the Azure VNet and the OCI VCN is INCORRECT as it won't provide a isolated connection.
Use Azure Private Link to create a private connection between the workload and the database is INCORRECT as Azure Private Link enables you to access Azure PaaS Services (for example, Azure Storage and SQL Database) and Azure hosted customer-owned/partner services over a pri-vate endpoint in your virtual network.
Use Azure ExpressRoute and Oracle FastConnect to create a private interconnection between the Azure VNet and the OCI VCN. is CORRECT. To create an integrated multi-cloud experience, Microsoft and Oracle offer direct interconnection between Azure and Oracle Cloud Infrastructure (OCI) through ExpressRoute and FastConnect. Through the ExpressRoute and FastConnect inter-connection, customers can experience low latency, high throughput, private direct connectivity be-tween the two clouds.
NEW QUESTION # 27
Which type of traffic is NOT supported by the OCI-Azure Interconnect?
- A. Traffic between an on-premises network and Azure VNet through the OCI VCN
- B. Traffic between an Azure VNet and peered OCI VCNs in the same region
- C. Traffic between an Azure VNet and an OCI VCN
- D. Traffic between an Azure VNet and peered OCI VCNs in different regions
Answer: A
Explanation:
You can connect your VNet and VCN so that traffic that uses private IP addresses goes over the cross-cloud connection.
The connection enables traffic to flow from the VNet through the connected VCN to a peered VCN in the same Oracle Cloud Infrastructure region, or a different region.
The Cross-cloud connection does not enable traffic between your on-premises network through the VCN to the VNet, or from your on-premises network through the VNet to the VCN.
NEW QUESTION # 28
How do Azure administrators and developers connect their applications to Oracle databases using Oracle Database Service for Azure?
- A. By connecting to the Oracle databases using connection strings
- B. By connecting to the Oracle databases using database links
- C. By manually creating complex cross-cloud deployments using the Interconnect
- D. By learning OCI and working in the OCI Console
Answer: A
Explanation:
The same way you do in Azure today. Each database resource created by Oracle Database Service for Azure gets an Azure connection string you can use to connect to the database from any Azure application.
During onboarding, Oracle Database Service for Azure creates network connections between the cloud environments.
During database provisioning, Oracle Database Service for Azure defines the DNS entries and connection strings needed to access the resource from Azure.
Azure developers (and applications) don't need to know anything about Oracle Database Service for Azure-all they need is the connection string. Oracle publishes the connection string on the custom dashboard it creates for the database in Azure, so developers don't have to leave the Azure portal to get what they need to access the database from their applications.
Hence, the CORRECT ANSWER is "By connecting to the Oracle databases using connection strings"
