Docker Certified Associate (DCA) Exam Sample Questions (Q155-Q160):

NEW QUESTION # 155
In the context of a swarm mode cluster, does this describe a node?
Solution: an instance of the Docker engine participating in the swarm

A. Yes
B. No

Answer: A

Explanation:
Explanation
In the context of a swarm mode cluster, an instance of the Docker engine participating in the swarm is indeed a node1. A node can be either a manager or a worker, depending on the role assigned by the swarm manager2. A manager node handles the orchestration and management of the swarm, while a worker node executes the tasks assigned by the manager2. A node can join or leave a swarm at any time, and the swarm manager will reconcile the desired state of the cluster accordingly1. References:

* 2: Manage nodes in a swarm | Docker Docs

NEW QUESTION # 156
Does this command create a swarm service that only listens on port 53 using the UDP protocol?
Solution. 'docker service create -name dns-cache -p 53:53 -constraint networking.protocol.udp=true dns-cache"

A. Yes
B. No

Answer: B

Explanation:
Explanation
This command does not create a swarm service that only listens on port 53 using the UDP protocol. The docker service create command creates a new service in a swarm cluster. The --name flag sets the name of the service. The -p or --publish flag publishes a port or a range of ports to the swarm. The --constraint flag applies a constraint to limit the set of nodes where the task can be scheduled. The networking.protocol.udp is not a valid constraint and will cause an error. To create a swarm service that only listens on port 53 using the UDP protocol, you need to use -p 53:53/udp instead. References:

https://docs.docker.com/engine/reference/commandline/service_create/#specify-service-constraints-constraint

NEW QUESTION # 157
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
These conditions are not sufficient for Kubernetes to dynamically provision a persistentVolume, because a default provisioner is not enough to determine how to create a persistentVolume. According to the official documentation, you also need to specify a default storageClass or annotate your persistentVolumeClaim with a specific storageClass name.
References: https://kubernetes.io/docs/concepts/storage/dynamic-provisioning/#defaulting-behavior

NEW QUESTION # 158
A server is running low on disk space. What command can be used to check the disk usage of images, containers, and volumes for Docker engine?

A. 'docker system ps'
B. 'docker system free'
C. 'docker system df'
D. 'docker system prune'

Answer: C

NEW QUESTION # 159
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. Yes
B. No

Answer: A

Explanation:
= Linux capabilities are a way of restricting the privileges of a process or a container. By default, Docker containers run with a reduced set of capabilities, which means they cannot perform certain operations that require higher privileges, such as setting the system time1. To allow a container to set the system time, you need to grant it the SYS_TIME capability by using the --cap-add option when running the container2. For example, docker run --cap-add SYS_TIME alpine date -s 12:00 would set the system time to 12:00 inside the alpine container3. Reference: Docker Documentation, Runtime privilege and Linuxcapabilities, Change system date time in Docker containers without impacting host, Is it possible to change time dynamically in docker container?
