NEW QUESTION # 115
Will This command list all nodes in a swarm cluster from the command line?
Solution. 'docker swarm nodes'
Answer: B
Explanation:
= The command 'docker swarm nodes' is not a valid command to list all nodes in a swarm cluster from the command line. The correct command is docker node ls, which can be run on a manager node to view the details of all the nodes in the swarm1. The docker swarm command is used to manage the swarm itself, not the nodes. For example, you can use docker swarm init to create a new swarm, or docker swarm join to add a node to an existing swarm2.

NEW QUESTION # 116
Is this statement correct?
Solution. A Dockerfile stores persistent data between deployments of a container
Answer: B
Explanation:
Explanation
A Dockerfile does not store persistent data between deployments of a container. A Dockerfile is a text document that contains instructions for building an image from a base image and other components. A Dockerfile does not store any data itself; it only defines how an image should be built. Persistent data between deployments of a container can be stored using volumes or bind mounts, which are ways of attaching external storage to containers.

NEW QUESTION # 117
You add a new user to the engineering organization in DTR.
Will this action grant them read/write access to the engineering/api repository?
Solution. Mirror the engineering/api repository to one of the user's own private repositories.
Answer: B
Explanation:
= Mirroring the engineering/api repository to one of the user's own private repositories will not grant them read/write access to the original repository. Mirroring is a feature that allows users to automatically sync images from one repository to another, either within the same DTR or across different DTRs. Mirroring does not affect the permissions or roles of the users or teams associated with the source or destination repositories. To grant a user read/write access to the engineering/api repository, the user needs to be added to a team that has the appropriate role for that repository, or the repository needs to be configured with the appropriate visibility and access settings.

Manage access to repositories

NEW QUESTION # 118
You want to create a container that is reachable from its host's network. Does this action accomplish this?
Solution: Use --link to access the container on the bridge network.
Answer: B
Explanation:
= The action of using --link to access the container on the bridge network does not accomplish the goal of creating a container that is reachable from its host's network. The --link option allows you to connect containers that are running on the same network, but it does not expose the container's ports to the host1. To create a container that is reachable from its host's network, you need to use the --network host option, which attaches the container to the host's network stack and makes it share the host's IP address2. Alternatively, you can use the --publish or -p option to map the container's ports to the host's ports3.

NEW QUESTION # 119
The following Docker Compose file is deployed as a stack:
Is this statement correct about this health check definition?
Solution.Health checks lest for app health ten seconds apart. Three failed health checks transition the container into "unhealthy" status.
Answer: A
Explanation:
The statement is correct. In the provided Docker Compose file, a health check is defined for the service "app". It uses curl to perform a health check on the application every 10 seconds (as specified by the "interval" parameter). If it fails three times (as specified by the "retries" parameter), then the container is marked as unhealthy. A health check is a way of checking the health of a running container and applying actions based on the result1. It can be used to monitor the status of the service and restart the container if it becomes unhealthy2. Reference:
