Docker Certified Associate (DCA) Exam Sample Questions (Q31-Q36):

NEW QUESTION # 31
A users attempts to set the system time from inside a Docker container are unsuccessful. Could this be blocking this operation?
Solution: Linux capabilities

A. No
B. Yes

Answer: B

Explanation:
Explanation
Linux capabilities are blocking this operation. Linux capabilities are a partitioning of the privileges traditionally associated with superuser into distinct units, known as capabilities, which can be independently enabled and disabled. Capabilities are used by Docker to restrict the operations that a container can perform on the host system. By default, Docker drops all capabilities except those needed for common operations, such as binding to ports below 1024 or mounting filesystems. One of the capabilities that is dropped by default is CAP_SYS_TIME, which allows setting the system clock. Therefore, a user cannot set the system time from inside a Docker container unless this capability is explicitly added. References:

https://man7.org/linux/man-pages/man7/capabilities.7.html

NEW QUESTION # 32
Is this a function of UCP?
Solution: image role-based access control

A. No
B. Yes

Answer: A

Explanation:
Explanation
Image role-based access control is not a function of UCP. UCP has its own built-in authentication mechanism and integrates with LDAP services. It also has role-based access control (RBAC), so that you can control who can access and make changes to your cluster and applications1. However, image role-based access control is a feature of Docker Trusted Registry (DTR), which integrates with UCP and allows you to manage the images you use for your applications2. DTR lets you define granular permissions for images, such as who can push, pull, delete, or scan them3. References: Universal Control Plane overview), Docker Trusted Registry overview), Docker Access Control)

NEW QUESTION # 33
Which of the following statements is true about secrets?

A. Secrets can be modified after they are created.
B. Secrets can be created from any node in the cluster.
C. Secrets can be created using standard input (STDIN) and a file.
D. Secret are stored unencrypted on manager nodes.

Answer: C

NEW QUESTION # 34
Will this Linux kernel facility limit a Docker container's access to host resources, such as CPU or memory?
Solution: seccomp

A. No
B. Yes

Answer: B

Explanation:
= Seccomp is a Linux kernel feature that allows you to restrict the actions available within the container. By using a seccomp profile, you can limit the system calls that a container can make, thus enhancing its security and isolation. Docker has a default seccomp profile that blocks some potentially dangerous system calls, such as mount, reboot, or ptrace. You can also pass a custom seccomp profile for a container using the --security-opt option. Seccomp can limit a container's access to host resources, such as CPU or memory, by blocking or filtering system calls that affect those resources, such as setpriority, sched_setaffinity, or mlock.

NEW QUESTION # 35
During development of an application meant to be orchestrated by Kubernetes, you want to mount the /data directory on your laptop into a container.
Will this strategy successfully accomplish this?
Solution: Add a volume to the pod that sets hostPath.path: /data, and then mount this volume into the pod's containers as desired.

A. No
B. Yes

Answer: A

Explanation:
The solution will not work because a hostPath volume mounts a file or directory from the host node's filesystem into the pod, not from the laptop1. The host node is the VM or machine where the pod is scheduled to run, not the machine where the kubectl commands are executed. Therefore, the /data directory on the laptop will not be accessible to the pod unless it is also present on the host node. A better solution would be to use a persistent volume that can be accessed from any node in the cluster, such as NFS, AWS EBS, or Azure Disk2. References:
