Oracle Cloud Infrastructure 2025 DevOps Professional Sample Questions (Q42-Q47):

NEW QUESTION # 42
You're using Oracle Cloud Infrastructure (OCI) DevOps service to automate your software releases to release features more frequently and with fewer errors. While deploying an update to production, one of your deployment stages failed.
What action should you perform in your Deployment Pipeline?

A. Automate back up and use the rerelease stage in the Deployment Pipeline.
B. Add Rescue and Trigger stages to automatically trigger the failed deployment.
C. Use OCI DevOps Trigger and Rerun tool to avoid downtime.
D. Roll back the failed stage in the pipeline to the previous successful released version

Answer: D

Explanation:
When a deployment stage fails in a OCI DevOps Deployment Pipeline, the recommended approach is to roll back to the previous successful version to ensure that the production environment remains in a stable state. This approach minimizes disruption and ensures that your system continues to function properly while the issue with the failed deployment is investigated and fixed.

NEW QUESTION # 43
The Kubernetes Master node serves as the central control plane for managing the cluster's resources and orchestrating workload deployment.
What are the primary responsibilities of the Kubernetes Master node?

A. The Master node is primarily tasked with executing application workloads and ensuring their availability within the cluster.
B. The Master node monitors network traffic within the cluster, ensuring secure communication and efficient data transfer between nodes.
C. The Master node oversees the scheduling and allocation of cluster resources, ensuring optimal utilization across nodes.
D. The Master node serves as a repository for storing container images, facilitating rapid deployment and scaling of applications.

Answer: C

Explanation:
The Kubernetes Master node is the central control plane responsible for managing the cluster's resources and orchestrating workload deployment. Its primary responsibilities include:
Scheduling: Deciding which workloads (pods) should run on which worker nodes, based on resource availability and scheduling constraints.
Resource Allocation: Allocating resources to workloads to ensure optimal utilization across nodes.
Cluster Management: Maintaining the desired state of applications, managing cluster events, and ensuring that all the components of the cluster are functioning properly.

NEW QUESTION # 44
Which of the following statement is INCORRECT with respect to a Dockerfile?

A. An ENV instruction sets the environment value to the key, and it is available for the subsequent build steps and in the running container as well.
B. WORKDIR instruction sets the working directory for any RUN, CMD, ENTRYPOINT instructions and not for COPY and ADD instructions in the Dockerfile.
C. The RUN instruction will execute any commands in a new layer on top of the current image and commit the results.
D. If CMD instruction provides default arguments for the ENTRYPOINT instruction, both should be specified in JSON format.

Answer: B

Explanation:
The WORKDIR instruction sets the working directory for all subsequent RUN, CMD, ENTRYPOINT, COPY, and ADD instructions in the Dockerfile. This means that after specifying WORKDIR, all these instructions will use the specified directory as their current working directory.

NEW QUESTION # 45
You're using Oracle Cloud Infrastructure (OCI) DevOps to automate your application deployment for frequent releases. In one of your automation steps, you'll create a deployment pipeline.
What does this deployment pipeline do in OCI DevOps?

A. It is used to store, manage, develop source code with OCI DevOps Code Repositories.
B. It is a sequence of steps for delivering and deploying your artifacts to a target environment.
C. It is a set of stages for your build process for building, testing and compiling software artifacts.
D. It takes a commit ID from your source code repositories and uses that source code to run your build instructions.

Answer: B

Explanation:
A deployment pipeline in OCI DevOps is used to automate the deployment of application artifacts to a target environment. It is a sequence of stages that includes steps such as approvals, traffic shifts, manual interventions, and the actual deployment of the artifacts to environments like Kubernetes clusters or compute instances.

NEW QUESTION # 46
As an engineer building and deploying applications using an OCI DevOps project, which two capabilities can help ensure the security and reliability of the code in the build and deployment pipelines? (Choose two.)

A. Using third-party tools like Sonatype, SonarQube, or OverOps to analyze code for security defects or bugs in code quality
B. Using Application Dependency Management (ADM) to identify security weaknesses in software applications by checking their dependencies
C. Using JIRA to track user stories and bug fixes in the development process
D. Using version control tools like Git or SVN to track and manage changes in the codebase
E. Using third-party tools like Ansible, Terraform, or OverOps to analyze code for security defects or bugs in code quality

Answer: A,B

Explanation:
Application Dependency Management (ADM) is a tool used to identify security weaknesses in software applications by analyzing their dependencies. Dependencies can often introduce vulnerabilities, and managing them properly is a critical part of ensuring application security.
Third-party tools like Sonatype and SonarQube can be used to analyze code for security defects or bugs in code quality. These tools help in identifying vulnerabilities, code smells, and other issues, which can improve the overall security and reliability of the code during the build process.
