最新的 Docker Certified Associate DCA 免費考試真題 (Q127-Q132):

問題 #127
The following Docker Compose file is deployed as a stack:

Is this statement correct about this health check definition?
Solution: Health checks test for app health ten seconds apart. Three failed health checks transition the container into "unhealthy" status.

A. No
B. Yes

答案：A

解題說明：
The statement is not entirely correct. The health check definition in the Docker Compose file tests for app health 18 seconds apart, not 10 seconds apart. Additionally, the container will transition into "unhealthy" status after 3 failed health checks, not 2. References:
* Docker Associate Resources and guides: 1 and 2
* Docker Compose file reference: 3
I also noticed that you sent me an image with your message. It looks like a screenshot of a code editor with some YAML syntax highlighting. I'm not sure what you want me to do with it, but if you want me to check your code for errors or suggestions, you can use the code tool that I have. Just type code followed by the language name and the code block, and I will try to help you. For example:
code
yaml version: '3.1' services: app: image: app1.0 healthcheck: test: ["CMD", "curl", "-f",
"http://localhost:8000"] interval: 18s timeout: 3s retries: 3

問題 #128
Will this command ensure that overlay traffic between service tasks is encrypted?
Solution: docker service create --network --encrypted

A. No
B. Yes

答案：A

解題說明：
= The command docker service create --network --encrypted will not ensure that overlay traffic between service tasks is encrypted. This is because the --network flag requires an argument that specifies the name or ID of the network to connect the service to1. The --encrypted flag is not a valid option for docker service create2. To encrypt overlay traffic between service tasks, you need to use the --opt encrypted flag on docker network create when you create the overlay network3. For example:
docker network create --opt encrypted --driver overlay my-encrypted-network Then, you can use the --network flag on docker service create to connect the service to the encrypted network.
For example:
docker service create --network my-encrypted-network my-service
References:
* docker service create | Docker Documentation
* docker service create | Docker Documentation
* Manage swarm service networks | Docker Docs
I hope this helps you understand the command and the encryption, and how they work with Docker and swarm. If you have any other questions related to Docker, please feel free to ask me.

問題 #129
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/udp dns-cache"

A. No
B. Yes

答案：A

解題說明：
Explanation
= The command 'docker service create -name dns-cache -p 53:53/udp dns-cache' is not correct and will not create a swarm service that only listens on port 53 using the UDP protocol. There are two errors in the command:
* The option -name should be --name with two dashes, otherwise it will be interpreted as a short option -n followed by an argument ame1.
* The option -p or --publish will publish the service port to the host port, which means the service will be reachable from outside the swarm2. To create a service that only listens on the internal network, you need to use the --publish-add option with the mode=ingress flag3.
The correct command should be:
docker service create --name dns-cache --publish-add mode=ingress,target=53,published=53,protocol=udp dns-cache References:
* docker service create | Docker Docs
* Publish ports on the host | Docker Docs
* Publish a port for a service | Docker Docs

問題 #130
In Kubernetes, to mount external storage to a filesystem path in a container within a pod, you would use a volume in the pod specification. This volume is populated with a persistentVolumeClaim that is bound to an existing persistentVolume. The persistentVolume is defined and managed by the storageClass which provides dynamic or static provisioning of the volume and determines what type of storage will be provided1. Reference:
* Dynamic Volume Provisioning | Kubernetes
Is this a supported user authentication method for Universal Control Plane?
Solution: Docker ID

A. No
B. Yes

答案：A

解題說明：
Docker Universal Control Plane (UCP) has its own built-in authentication mechanism and integrates with LDAP services1.It also has role-based access control (RBAC), so that you can control who can access and make changes to your cluster and applications1.However, there is no mention of Docker ID being a supported user authentication method for UCP in the resources provided1234.

問題 #131
In the context of a swarm mode cluster, does this describe a node?
Solution: a physical machine participating in the swarm

A. No
B. Yes

答案：A

問題 #132
