Oracle Cloud Infrastructure 2025 DevOps Professional Sample Questions (Q17-Q22):

NEW QUESTION # 17
You are a developer and have been asked to develop an e-commerce website for your organization. It must support a variety of clients including desktop browsers, mobile browsers and native mobile applications.
Which two approaches can you use to build the application to achieve deployment independence, easier technology upgrades, and resiliency to architecture changes? (Choose two.)

A. Implement each module as an independent service/process which can be replaced, updated, or deleted without disrupting the rest of the application.
B. Use microservices architecture as it eliminates any long-term commitment to a technology stack.
C. Choose monolithic approach over microservices as it has better fault isolation capability.
D. Use monolithic approach, as it allows you to easily redeploy your applications to perform frequent updates.
E. Use monolithic approach to as it makes it easier to incrementally adapt to newer technology.

Answer: A,B

Explanation:
By implementing each module as an independent service/process (which is a core feature of microservices architecture), you can replace, update, or delete services without affecting the rest of the application. This ensures deployment independence and makes it easier to adapt to architecture changes or technology upgrades without major disruptions.
Microservices architecture allows each service to be built with the best-suited technology stack for its specific function. This flexibility ensures that you are not tied to a single technology for the entire application, making future technology upgrades easier and eliminating long-term technology commitments.

NEW QUESTION # 18
In Kubernetes clusters created by Container Engine for Kubernetes, how is data in etcd encrypted at rest by default?

A. Encryption using TLS certificates
B. Using encryption keys managed by Oracle using a master encryption key
C. Using encryption keys managed by the user
D. No encryption applied

Answer: B

Explanation:
In Kubernetes clusters created by Oracle Container Engine for Kubernetes (OKE), data in etcd (the key-value store that holds cluster state and configuration data) is encrypted at rest by default using encryption keys managed by Oracle. Oracle manages the encryption using a master encryption key to protect sensitive data.

NEW QUESTION # 19
You host your application on a stack in Oracle Cloud Infrastructure (OCI) Resource Manager. Because of recent growth in your user base, you decide to add a CIDR block to your VCN, add a subnet, and provision a compute instance in it.
Which statement is true?

A. You can make the changes to the Terraform code, run a Drift Detection job, and Resource Manager will provision the new resources.
B. You need to provision the new resources in the OCI console first, then add them later to the Terraform configuration and state.
C. You can make the changes to the Terraform code, run an Apply job, and Resource Manager will provision the new resources.
D. You need to provision a new stack because Terraform uses immutable infrastructure.

Answer: C

Explanation:
Oracle Cloud Infrastructure (OCI) Resource Manager uses Terraform to manage infrastructure resources. If you need to add new resources (e.g., a new CIDR block, subnet, and compute instance), you can simply make the necessary changes to the Terraform code defining the stack.
After modifying the Terraform configuration to include the new resources, you can run an Apply job in Resource Manager. The Apply job will provision the new resources in your OCI environment according to the updated Terraform code.

NEW QUESTION # 20
Which statement is false about OCI Resource Manager (RM)?

A. RM can render custom "Application Information" pages for stacks.
B. Resources provisioned through RM cannot be destroyed from outside of RM.
C. RM can generate Terraform based on the resources in a compartment.
D. RM can mirror repositories from GitHub and GitLab.

Answer: B

Explanation:
Resources provisioned through OCI Resource Manager (RM) can still be modified or destroyed from outside of RM, such as using the OCI Console, CLI, or other APIs. RM manages the lifecycle of resources created by its Terraform configurations, but it does not prevent other tools or methods from modifying or deleting those resources.

NEW QUESTION # 21
How can you scale a deployment named nodejs-deployment to have two replicas?

A. kubectl set replicas deployment nodejs-deployment --replicas=2
B. kubectl adjust deployment nodejs-deployment --replicas=2
C. kubectl resize deployment nodejs-deployment --replicas=2
D. kubectl scale deployment nodejs-deployment --replicas=2

Answer: D

Explanation:
The kubectl scale command is used to scale the number of replicas in a deployment. By specifying the --replicas flag, you define the desired number of replicas for the deployment.
(kubectl set replicas) is not the correct syntax for scaling a deployment.
(kubectl resize) is not a valid command for scaling a deployment.
(kubectl adjust) is also not a valid Kubernetes command.
