Docker Certified Associate (DCA) Exam Sample Questions (Q151-Q156):NEW QUESTION # 151
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: label contraints
A. Yes
B. No
Answer: A
Explanation:
Label constraints can be used to schedule containers to meet the security policy requirements. Label constraints allow you to specify which nodes a service can run on based on the labels assigned to the nodes1. For example, you can label the nodes that are intended for development with env=dev and the nodes that are intended for production with env=prod. Then, you can use the --constraint flag when creating a service to restrict it to run only on nodes with a certain label value. For example, docker service create --name dev-app --constraint 'node.labels.env == dev' ... will create a service that runs only on development nodes2. Similarly, docker service create --name prod-app --constraint 'node.labels.env == prod' ... will create a service that runsonly on production nodes3. This way, you can ensure that development and production containers are running on separate nodes in a given Swarm cluster. Reference:

NEW QUESTION # 152
Will this command mount the host's '/data' directory to the ubuntu container in read-only mode?
Solution: 'docker run -v /data:/mydata --mode readonly ubuntu'
A. No
B. Yes
Answer: A
Explanation:
Explanation
This command will not mount the host's '/data' directory to the ubuntu container in read-only mode, because it has an incorrect option for making the volume read-only. According to the official documentation, the correct command should be:
docker run -v /data:/mydata:ro ubuntu
The incorrect option is:
The --mode flag does not exist and should be replaced by a :ro suffix to make the volume read-only.

Will this configuration achieve fault tolerance for managers in a swarm?
Solution: an odd number of manager nodes, totaling more than two
A. Yes
B. No
Answer: A
Explanation:
Explanation
This configuration will achieve fault tolerance for managers in a swarm, because an odd number of manager nodes allows for quorum-based consensus among managers and avoids split-brain scenarios. According to the official documentation, having more than two manager nodes ensures that there is always at least one manager available in case of failures.
