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. If CMD instruction provides default arguments for the ENTRYPOINT instruction, both should be specified in JSON format.
- C. WORKDIR instruction sets the working directory for any RUN, CMD, ENTRYPOINT instructions and not for COPY and ADD instructions in the Dockerfile.
- D. The RUN instruction will execute any commands in a new layer on top of the current image and commit the results.
Answer: C
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.

Adding an approval stage helps ensure that a secure and reliable deployment is achieved by requiring human verification and approval before proceeding with the deployment to production.
This step adds an extra layer of control to prevent unintended issues from moving forward without further review. It is a common practice in CI/CD pipelines to have an approval step, especially for critical deployments.
NEW QUESTION # 37
What is the correct approach to upgrade an Oracle Container Engine for Kubernetes (OKE) Cluster to a newer version of Kubernetes?
- A. Upgrade the control plane, then upgrade the node pools.
- B. Upgrade the node pools one at a time, then once all node pools are upgraded, upgrade the control plane.
- C. Initiate the automated upgrade process using the OCI Console, CLI, or API.
- D. Initiate the control plane and node pool upgrades simultaneously.
Answer: A
Explanation:
The correct approach to upgrade an Oracle Container Engine for Kubernetes (OKE) cluster involves first upgrading the Kubernetes control plane, followed by upgrading the node pools. The control plane must be upgraded first to ensure compatibility with newer versions of Kubernetes, as node pools rely on the control plane for orchestration and management.
After upgrading the control plane, each node pool is upgraded to match the new Kubernetes version. This phased approach ensures the cluster remains in a stable state during the upgrade.
NEW QUESTION # 38
How can you scale a deployment named nodejs-deployment to have two replicas?
- A. kubectl scale deployment nodejs-deployment --replicas=2
- B. kubectl adjust deployment nodejs-deployment --replicas=2
- C. kubectl set replicas deployment nodejs-deployment --replicas=2
- D. kubectl resize deployment nodejs-deployment --replicas=2
Answer: A
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.
NEW QUESTION # 39
