Docker Certified Associate (DCA) Exam Sample Questions (Q124-Q129):

NEW QUESTION # 124
Which of the following is supported by control groups?

A. Collect net
B. Manage certificates
C. Limit CPU usage within a container
D. Isolate processes in a container

Answer: C

NEW QUESTION # 125
A company's security policy specifies that development and production containers must run on separate nodes in a given Swarm cluster.
Can this be used to schedule containers to meet the security policy requirements?
Solution: node taints

A. Yes
B. No

Answer: B

Explanation:
Explanation
Node taints cannot be used to schedule containers to meet the security policy requirements, because node taints are a Kubernetes concept and not a Swarm concept. According to the official documentation, node taints are used to mark nodes with certain attributes that prevent pods from being scheduled on them unless they have matching tolerations.

NEW QUESTION # 126
One of several containers in a pod is marked as unhealthy after failing its livenessProbe many times. Is this the action taken by the orchestrator to fix the unhealthy container?
Solution: Kubernetes automatically triggers a user-defined script to attempt to fix the unhealthy container.

A. Yes
B. No

Answer: B

Explanation:
Explanation
Kubernetes does not automatically trigger a user-defined script to attempt to fix the unhealthy container, because Kubernetes does not have such a feature. According to the official documentation, Kubernetes only supports three types of probes: exec, httpGet, and tcpSocket, and none of them can execute arbitrary scripts.

NEW QUESTION # 127
The Kubernetes yaml shown below describes a networkPolicy.

Will the networkPolicy BLOCK this trafftc?
Solution. a request issued from a pod bearing only the tier: frontend label, to a pod bearing the tier: backend label

A. No
B. Yes

Answer: B

Explanation:
The provided Kubernetes NetworkPolicy YAML configuration indicates that the policy applies to pods with the label tier: backend in the default namespace1. The ingress rule allows traffic from pods with the label tier:
api1. Therefore, a request issued from a pod bearing only the tier: frontend label to a pod bearing the tier:
backend label will be blocked by this networkPolicy1. This is because the networkPolicy does not have a rule allowing ingress from pods with the tier: frontend label1. For more information on Kubernetes NetworkPolicies, you can refer to the Kubernetes Documentation on Network Policies.

NEW QUESTION # 128
An application image runs in multiple environments, with each environment using different certificates and ports.
Is this a way to provision configuration to containers at runtime?
Solution: Create a Dockerfile for each environment, specifying ports and ENV variables for certificates.

A. Yes
B. No

Answer: B

Explanation:
While creating a Dockerfile for each environment is a possible solution, it is not the most efficient or scalable way to provision configuration to containers at runtime. Docker provides several mechanisms to inject configuration into containers at runtime, such as environment variables, command line arguments, Docker secrets for sensitive data, or even configuration files mounted as volumes. These methods allow the same Docker image to be used across multiple environments, promoting immutability and consistency across your deployments. Creating a separate Dockerfile for each environment would mean maintaining multiple versions of the Dockerfile, which could lead to inconsistencies and is generally not a recommended practice.

NEW QUESTION # 129
......

One of the key factors for passing the exam is practice. Candidates must use Docker DCA practice test material to be able to perform at their best on the real exam.
