Docker Certified Associate (DCA) Exam Sample Questions (Q59-Q64):

NEW QUESTION # 59
Two development teams in your organization use Kubernetes and want to deploy their applications while ensuring that Kubernetes-specific resources, such as secrets, are grouped together for each application.
Is this a way to accomplish this?
Solution: Create one namespace for each application and add all the resources to it.

  • A. Yes
  • B. No

Answer: A

Explanation:
Namespaces in Kubernetes are a way to create and organize virtual clusters within physical clusters where we can isolate a group of resources within a single cluster1. Namespace helps to organize resources such as pods, services, and volumes within the cluster2. By creating one namespace for each application and adding all the resources to it, the development teams can ensure that Kubernetes-specific resources, such as secrets, are grouped together for each application. This also provides a scope for names, a mechanism to attach authorization and policy, and a way to divide cluster resources between multiple users3. Reference:

NEW QUESTION # 60
In Docker Trusted Registry, is this how a user can prevent an image, such as 'nginx:latest', from being overwritten by another user with push access to the repository?
Solution: Use the DTR web Ul to make all tags in the repository immutable.

  • A. Yes
  • B. No

Answer: B

Explanation:
n: = Using the DTR web UI to make all tags in the repository immutable is not a good way to prevent an image, such as 'nginx:latest', from being overwritten by another user with push access to the repository. This is because making all tags immutable would prevent any updates to the images in the repository, which may not be desirable for some use cases. For example, if a user wants to push a new version of 'nginx:latest' with a security patch, they would not be able to do so if the tag is immutable. A better way to prevent an image from being overwritten by another user is to use the DTR web UI to create a promotion policy that restricts who can push to a specific tag or repository1. Alternatively, the user can also use the DTR API to create a webhook that triggers a custom action when an image is pushed to a repository2. References:

* Create webhooks | Docker Docs


NEW QUESTION # 61
Are these conditions sufficient for Kubernetes to dynamically provision a persistentVolume, assuming there are no limitations on the amount and type of available external storage?
Solution: A default provisioner is specified, and subsequently a persistentVolumeClaim is created.

  • A. Yes
  • B. No

Answer: B

Explanation:
Explanation
= The conditions are not sufficient for Kubernetes to dynamically provision a persistentVolume, because they are missing a StorageClass object. A StorageClass object defines which provisioner should be used and what parameters should be passed to that provisioner when dynamic provisioning is invoked. A persistentVolumeClaim must specify the name of a StorageClass in its storageClassName field to request a dynamically provisioned persistentVolume. Without a StorageClass, Kubernetes cannot determine how to provision the storage for the claim. References:
* Dynamic Volume Provisioning | Kubernetes
* Persistent volumes and dynamic provisioning | Google Kubernetes Engine ...
* Dynamic Provisioning and Storage Classes in Kubernetes or Dynamic Provisioning and Storage Classes in Kubernetes


NEW QUESTION # 62
Is this a type of Linux kernel namespace that provides container isolation?
Solution: Network

  • A. Yes
  • B. No

Answer: B


NEW QUESTION # 63
You have just executed 'docker swarm leave' on a node. What command can be run on the same node to confirm it has left the cluster?

  • A. docker system info
  • B. docker system status
  • C. docker node ls
  • D. docker system status

Answer: A
