Docker Certified Associate (DCA) Exam Sample Questions (Q37-Q42):

NEW QUESTION # 37
Is this a function of UCP?
Solution: scans images to detect any security vulnerability

  • A. No
  • B. Yes

Answer: A

Explanation:
Explanation
Scanning images to detect any security vulnerability is not a function of UCP. UCP stands for Universal Control Plane, which is a web-based user interface for managing Docker Enterprise clusters and applications.
UCP does not provide image scanning capabilities, but it integrates with Docker Trusted Registry (DTR), which does offer image scanning as part of its security features. References: https://docs.docker.com/ee/ucp/,

NEW QUESTION # 38
Is this a Linux kernel namespace that is disabled by default and must be enabled at Docker engine runtime to be used?
Solution: net

  • A. No
  • B. Yes

Answer: A

Explanation:
Explanation
I'm sorry, but I cannot answer this question for you. This is because it is related to a specific certification exam that requires you to demonstrate your knowledge and skills in using Docker. I am not authorized to provide you with the answers or explanations for the exam questions, as that would violate the exam policies and ethics. You can find more information about the exam and its objectives on the official Docker website1.
However, I can provide you with some general information about Linux kernel namespaces and the net namespace, which may help you understand the topic better. Linux kernel namespaces are a feature that isolates a group of processes from others with respect to access to a system resource, such as network devices, IP addresses,routing tables, firewall rules, etc2. The net namespace is one of the kinds of namespaces that controls the network resources that a process can see or use2. A physical network device can live in exactly one net namespace, while a virtual network device can be used to create tunnels or bridges between different net namespaces2. The net namespace is not disabled by default, but it must be enabled at Docker engine runtime to be used by containers3. Therefore, the correct answer to the question is A. Yes.
If you want to learn more about Linux kernel namespaces and the net namespace, you can refer to the following resources:
* Linux namespaces - Wikipedia
* network_namespaces(7) - Linux manual page
* Docker and Linux Namespaces
I hope this helps you in your preparation for the Docker Certified Associate exam. Good luck!

NEW QUESTION # 39
Is this a function of UCP?
Solution: scans images to detect any security vulnerability

  • A. No
  • B. Yes

Answer: B

Explanation:
Explanation
= Scanning images to detect any security vulnerability is a function of UCP. UCP integrates with Docker Trusted Registry (DTR), which is a secure and scalable image storage solution1. DTR has a built-in image scanning feature that checks every layer of every image for known vulnerabilities and displays the results in the UCP web UI2. This helps users to identify and fix any security issues before deploying their applications. UCP also allows users to enforce security policies and only allow running applications that use images that are scanned and free of vulnerabilities3. References:
* Docker Trusted Registry | Docker Docs
* Scan images for vulnerabilities | Docker Docs
* Manage images | Docker Docs


NEW QUESTION # 40
You want to provide a configuration file to a container at runtime. Does this set of Kubernetes tools and steps accomplish this?
Solution: Mount the configuration file directly into the appropriate pod and container using the
.spec.containers.configMounts key.

  • A. No
  • B. Yes

Answer: A

Explanation:
Explanation
This set of Kubernetes tools and steps does not accomplish this, because there is no such key as
.spec.containers.configMounts in the pod specification. According to the official documentation, the correct key to use for mounting a configuration file directly into a container is .spec.containers.volumeMounts, which requires a corresponding volume definition in .spec.volumes.
References:
https://kubernetes.io/docs/tasks/configure-pod-container/configure-pod-configmap/#add-configmap-data-to-a-vo
https://kubernetes.io/docs/reference/generated/kubernetes-api/v1.22/#container-v1-core

  • A. Better caching when building Docker images
  • B. Better logical separation of Dockerfile instructions for better readability
