Docker Certified Associate (DCA) Exam Sample Questions (Q69-Q74):

NEW QUESTION # 69
Will this command display a list of volumes for a specific container?
Solution. 'docker container logs nginx -volumes'

A. No
B. Yes

Answer: A

Explanation:
The command docker container logs nginx -volumes will not display a list of volumes for a specific container. The docker container logs command shows the logs of a container, which are usually the standard output and standard error of the main process running in thecontainer1. The -volumes flag is not a valid option for this command, and will result in an error message2. To display a list of volumes for a specific container, you can use the docker inspect command with a filter option, such as docker inspect -f '{{ .Mounts }}' nginx3. This will show the source, destination, mode, type, and propagation of each volumemounted in the container4. Reference: docker container logs, docker container logs nginx -volumes, docker inspect, docker inspect -f '{{ .Mounts }}' nginx

NEW QUESTION # 70
You are running only Kubernetes workloads on a worker node that requires maintenance, such as installing patches or an OS upgrade.
Which command must be run on the node to gracefully terminate all pods on the node, while marking the node as unschedulable?

A. `docker swarm leave'
B. `kubectl drain <node name>'
C. `docker node update -availability drain <node name>
D. `kubectl cordon <node name>

Answer: B

Explanation:
The command kubectl drain <node name> is the correct one to run on the node to gracefully terminate all pods on the node, while marking the node as unschedulable. This command will safely evict all the pods from the node before you perform maintenance on the node, such as installing patches or an OS upgrade1. It will respect the PodDisruptionBudgets you have specified, if any, and allow the pod's containers to gracefully terminate1. It will also mark the node as unschedulable, so that no new pods can be scheduled on the node until it is ready1.
The other commands are not correct because:
* docker swarm leave will make the node leave the swarm cluster, but it will not affect the Kubernetes workloads on the node2.
* docker node update -availability drain <node name> will change the availability of the node to drain, which means that no new tasks can be assigned to the node, but it will not terminate the existing pods on the node3.
* kubectl cordon <node name> will mark the node as unschedulable, but it will not evict the pods on the node4.
Reference:
* Safely Drain a Node | Kubernetes
* [docker swarm leave | Docker Docs]
* [docker node update | Docker Docs]
* [kubectl cordon | Kubernetes Docs]

NEW QUESTION # 71
You want to create a container that is reachable from its host's network.
Does this action accomplish this?
Solution.Use network connect to access the container on the bridge network.

A. No
B. Yes

Answer: A

Explanation:
= Using network connect to access the container on the bridge network does not accomplish creating a container that is reachable from its host's network. The network connect command connects a container to an existing network, but it does not expose the container's ports to the host1. The bridge network is the default network that Docker creates for containers, and it provides isolation from the host network2. To create a container that is reachable from its host's network, you need to use the host network driver, which disables network isolation and uses the host's network stack directly3. Alternatively, you can use the port mapping feature to publish specific ports of the container to the host4. Reference:
docker network connect | Docker Docs
Bridge network driver | Docker Docs
Host network driver | Docker Docs
Publish ports on the host | Docker Docs

NEW QUESTION # 72
Will this command list all nodes in a swarm cluster from the command line?
Solution: 'docker swarm nodes'

A. No
B. Yes

Answer: A

Explanation:
= The correct command to list all nodes in a swarm cluster from the command line is docker node ls, not docker swarm nodes. The docker node command allows you to manage nodes in a swarm, such as listing, inspecting, updating, or removingnodes1. The docker swarm command allows you to manage the swarm itself, such as initializing, joining, leaving, or updating the swarm2. Reference:
Manage nodes in a swarm | Docker Docs
Manage a swarm | Docker Docs

NEW QUESTION # 73
Which of the following commands will ensure that overlay traffic between service tasks is encrypted?

A. docker service create --network <network-name> --encrypted <service-name>
B. docker service create --network <network-name> --secure <service-name>
C. docker network create -d overlay --secure <network-name>
D. docker network create -d overlay -o encrypted=true <network-name>

Answer: D
