問題 #86
Is this a supported user authentication method for Universal Control Plane?
Solution.x.500

A. Yes
B. No

答案：B

解題說明：
Explanation
x.500 is not a supported user authentication method for Universal Control Plane (UCP). UCP supports two types of user authentication methods: built-in and external1. Built-in authentication uses the UCP's own database to store and verify user credentials. External authentication uses an external LDAP or Active Directory service to manage user accounts and passwords1. x.500 is a standard for directory services, which can be used by LDAP or Active Directory, but it is not a user authentication method by itself2. References:
* User authentication | Docker Docs
* X.500 - Wikipedia

問題 #87
In Docker Trusted Registry, how would a user prevent an image, for example 'nginx:latest' from being overwritten by another user with push access to the repository?

A. Keep a backup copy of the image on another repository.
B. Remove push access from all other users.
C. Tag the image with 'nginx:immutable'
D. Use the DTR web UI to make the tag immutable.

答案：D

問題 #88
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. No
B. Yes

答案：B

解題說明：
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

問題 #89
An application image runs in multiple environments, with each environment using different certificates and ports. Is this a way to provision configuration to containers at runtime?
Solution. Create a Dockerfile for each environment, specifying ports and Docker secrets for certificates.

A. Yes
B. No

答案：B

解題說明：
Creating a Dockerfile for each environment, specifying ports and Docker secrets for certificates is not a way to provision configuration to containers at runtime. A Dockerfile is a text document that contains all the commands a user could call on the command line to assemble an image1. A Dockerfile is used to build an image, not to run a container. Once an image is built, the configuration specified in the Dockerfile cannot be changed at runtime. To provision configuration to containers at runtime, you need to use a different mechanism, such as environment variables, command-line arguments, or config maps234. References:
* Dockerfile reference | Docker Docs
* Environment variables in Compose | Docker Docs
* Override the default command | Docker Docs
* Configuration management with Containers | Kubernetes

問題 #90
One of several containers in a pod is marked as unhealthy after failing its livenessProbe many times. Is this the action taken by the orchestrator to fix the unhealthy container?
Solution: Kubernetes automatically triggers a user-defined script to attempt to fix the unhealthy container.

A. Yes
B. No

答案：B

解題說明：
Explanation
= I cannot give you a comprehensive explanation, but I can tell you that the question is about Kubernetes, not Docker. Kubernetes is an orchestrator that can manage multiple containers in a pod, which is a group of containers that share a network and storage. A livenessProbe is a way to check if a container is alive and ready to serve requests. If a container fails its livenessProbe, Kubernetes will try to restart it by default. However, you can also specify a custom action to take when a container fails its livenessProbe, such as running a script to fix the problem. This is what the solution is referring to. You will need to understand the difference between Kubernetes and Docker, and how they work together, to answer this question correctly. References: You can find some useful references for this question in the following links:
* Kubernetes Pods
* Configure Liveness, Readiness and Startup Probes
* Docker and Kubernetes
