NEW QUESTION 27
You run 5 Oracle Cloud Infrastructure (OCI) Virtual Machine instances on an OCI dedicated virtual host. How will this deployment be billed?
- A. Only the dedicated virtual machine host will be billed
- B. All 5 instances will be billed on the basis of the number of OCPUs
- C. The dedicated virtual machine host all 5 instances, and the boot volume of each instance will be billed
- D. The dedicated virtual machine host and the boot volumes of each instance will be billed
Answer: D
Explanation:
Explanation
You must create a dedicated virtual machine host before you can place any instances on it. When creating the dedicated virtual machine host, you select an availability domain and fault domain to launch it in. All the VM instances that you place on the host will subsequently be created in this availability domain and fault domain.
You also select a compartment when you create the dedicated virtual machine host, but you can move the host to a new compartment later without impacting any of the instances placed on it. You can also create the instances in a different compartment than the dedicated virtual machine host, or move them to difference compartments after they have been launched.
You are billed for the dedicated virtual machine host as soon as you create it, but you are not billed for any of the individual VM instances you place on it. You will still be billed for image licensing costs if they apply to the image you are using for the VM instances.

NEW QUESTION 31
A banking platform has been re-designed to a microservices based architecture using Docker containers for deployment.
Which service can you use to deploy containers on Oracle Cloud Infrastructure (OCI)?
- A. File Storage Service
- B. Streaming Service
- C. Container Engine for Kubernetes (OKE)
- D. API Gateway
Answer: C
Explanation:
Explanation
Oracle Cloud Infrastructure Container Engine for Kubernetes is a fully-managed, scalable, and highly available service that you can use to deploy your containerized applications to the cloud. Use Container Engine for Kubernetes (sometimes abbreviated to just OKE) when your development team wants to reliably build, deploy, and manage cloud-native applications. You specify the compute resources that your applications require, and Container Engine for Kubernetes provisions them on Oracle Cloud Infrastructure in an existing OCI tenancy.
Container Engine for Kubernetes uses Kubernetes - the open-source system for automating deployment, scaling, and management of containerized applications across clusters of hosts. Kubernetes groups the containers that make up an application into logical units (called pods) for easy management and discovery.
You can access Container Engine for Kubernetes to define and create Kubernetes clusters using the Console and the REST API. You can access the clusters you create using the Kubernetes command line (kubectl), the Kubernetes Dashboard, and the Kubernetes API.
Container Engine for Kubernetes is integrated with Oracle Cloud Infrastructure Identity and Access Management (IAM), which provides easy authentication with native Oracle Cloud Infrastructure identity functionality.

NEW QUESTION 34
Which Oracle cloud infrastructure capability can be used to protect against power failures within an availability Domain?
- A. Fault Domains
- B. Top of Rack Switch
- C. Services Cells
- D. Data Plane
Answer: A
Explanation:
Explanation
A fault domain is a grouping of hardware and infrastructure within an availability domain. Each availability domain contains three fault domains. Fault domains provide anti-affinity: they let you distribute your instances so that the instances are not on the same physical hardware within a single availability domain. A hardware failure or Compute hardware maintenance event that affects one fault domain does not affect instances in other fault domains. In addition, the physical hardware in a fault domain has independent and redundant power supplies, which prevents a failure in the power supply hardware within one fault domain from affecting other fault domains.
To control the placement of your compute instances, bare metal DB system instances, or virtual machine DB system instances, you can optionally specify the fault domain for a new instance or instance pool at launch time. If you don't specify the fault domain, the system selects one for you. Oracle Cloud Infrastructure makes a best-effort anti-affinity placement across different fault domains, while optimizing for available capacity in the availability domain. To change the fault domain for an instance, terminate it and launch a new instance in the preferred fault domain.
Use fault domains to do the following things:
Protect against unexpected hardware failures or power supply failures.
Protect against planned outages because of Compute hardware maintenance.
NEW QUESTION 35

- B. Health Insurance Portability and Accountability Act (HIPAA)
- C. NERC Critical Infrastructure Protection Standards

NEW QUESTION 39
Which kind of scaling is supported by virtual machines in Oracle Cloud Infrastructure Compute service?
- A. Only scaling in
- B. Scaling up or down, and scaling in or out
- C. Only scaling out
- D. Only scaling up or down
Answer: B
Explanation:
Explanation
Horizontal scaling means that you scale by adding more machines into your pool of resources whereas Vertical scaling means that you scale by adding more power (CPU, RAM) to an existing machine.
An easy way to remember this is to think of a machine on a server rack, we add more machines across the horizontal direction and add more resources to a machine in the vertical direction.
With horizontal-scaling it is often easier to scale dynamically by adding more machines into the existing pool
- Vertical-scaling is often limited to the capacity of a single machine, scaling beyond that capacity often involves downtime and comes with an upper limit.

NEW QUESTION 41
Which Oracle Cloud Infrastructure service leverages Terraform to configure infrastructure as code?
- A. Events
- B. Oracle Functions
- C. Compartment Explorer
- D. Resource Manager
Answer: D
Explanation:
Explanation
Resource Manager is an Oracle Cloud Infrastructure service that allows you to automate the process of provisioning your Oracle Cloud Infrastructure resources. Using Terraform, Resource Manager helps you install, configure, and manage resources through the "infrastructure-as-code" model.
A Terraform configuration codifies your infrastructure in declarative configuration files. Resource Manager allows you to share and manage infrastructure configurations and state files across multiple teams and platforms. This infrastructure management can't be done with local Terraform installations and Oracle Terraform modules alone. For more information about the Oracle Cloud Infrastructure Terraform provider, see Terraform Provider. For a general introduction to Terraform and the "infrastructure-as-code" model, see https://www.terraform.io.
NEW QUESTION 42
Which is an example of Edge Services in Oracle Cloud Infrastructure (OCI)?
- A. Virtual Cloud Network (VCN)
- B. Virtual Firewall
- C. Web Application Firewall
- D. Object Storage
Answer: C
Explanation:
Explanation
Oracle Cloud Infrastructure Web Application Firewall (WAF) is a cloud-based, Payment Card Industry (PCI) compliant, global security service that protects applications from malicious and unwanted internet traffic.
WAF can protect any internet facing endpoint, providing consistent rule enforcement across a customer's applications.
WAF provides you with the ability to create and manage rules for internet threats including Cross-Site Scripting (XSS), SQL Injection and other OWASP-defined vulnerabilities. Unwanted bots can be mitigated while tactically allowed desirable bots to enter. Access rules can limit based on geography or the signature of the request.
NEW QUESTION 43
Which OCI storage service does not provide encryption for data at rest?
- A. Local NVMe
- B. File Storage
- C. Block Volume
- D. Object Storage
Answer: A
Explanation:
Explanation
NVMe stands for non-volatile memory express. It is a storage protocol created to fasten the transfer of data between enterprise and client systems and solid-state drives (SSDs) over a computer's high-speed Peripheral Component Interconnect Express bus. The characteristics are:
1) Local NVMe is NVMe SSD-based temporary storage.
2) It is the locally-attached NVMe devices to the OCI compute instance
3) It is used very high storage performance requirements, lots of throughput, lots of IOPS, local storage and when you don't want to go out on network
4) Oracle does not protect in any way through RAID, or snapshots, or backup out of the box and data is not encrypted at rest.
