Question No. 1

How can system administrators ensure that only signed images from Oracle Cloud Infrastructure Registry are deployed to a Container Engine for Kubernetes cluster?

ABy disabling access to the Container Engine for Kubernetes cluster

BBy manually inspecting each image before deployment

CBy encrypting the images using a custom encryption algorithm

DBy configuring an image verification policy for the cluster

Show Answer

Correct Answer: D

Image verification policies are used to ensure that only trusted and signed images are deployed to an Oracle Kubernetes Engine (OKE) cluster. By configuring such policies, administrators can enforce that images must be signed and come from trusted sources, such as the Oracle Cloud Infrastructure Registry.

Question No. 2

How can you scale a deployment named nodejs-deployment to have two replicas?

Akubectl set replicas deployment nodejs-deployment --replicas=2

Bkubectl resize deployment nodejs-deployment --replicas=2

Ckubectl adjust deployment nodejs-deployment --replicas=2

Dkubectl scale deployment nodejs-deployment --replicas=2

Show Answer

Correct Answer: D

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.

Question No. 3

You are a DevOps engineer working on a project that requires you to push and pull Docker images to and from Oracle Cloud Infrastructure Registry (Container Registry) using Docker CLI. You have been given access to Container Registry and have installed Docker CLI on your local machine.

Which should you create and use to securely authenticate and store your Docker image in a private Docker registry in OCI?

AAuth Token

BJSON Web Token

CSSH Key Pair

DMaster Encryption Key in OCI Vault

Show Answer

Correct Answer: A

To authenticate with the Oracle Cloud Infrastructure Registry (Container Registry) when using the Docker CLI, you need to use an Auth Token. The Auth Token is created in the OCI console and acts as a password for the Docker login command, providing secure access to the container registry.

Question No. 4

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.)

AUse monolithic approach, as it allows you to easily redeploy your applications to perform frequent updates.

BImplement each module as an independent service/process which can be replaced, updated, or deleted without disrupting the rest of the application.

CUse monolithic approach to as it makes it easier to incrementally adapt to newer technology.

DChoose monolithic approach over microservices as it has better fault isolation capability.

EUse microservices architecture as it eliminates any long-term commitment to a technology stack.

Show Answer

Correct Answer: B, E

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.

Question No. 5

Which of the following statement is INCORRECT with respect to a Dockerfile?

AWORKDIR instruction sets the working directory for any RUN, CMD, ENTRYPOINT instructions and not for COPY and ADD instructions in the Dockerfile.

BAn 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.

CThe RUN instruction will execute any commands in a new layer on top of the current image and commit the results.

DIf CMD instruction provides default arguments for the ENTRYPOINT instruction, both should be specified in JSON format.

Show Answer

Correct Answer: A

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.
