NEW QUESTION # 95
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. No
  • B. Yes

Answer: A

Explanation:
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


NEW QUESTION # 96
Will this command list all nodes in a swarm cluster from the command line?
Solution. 'docker inspect nodes

  • A. No
  • B. Yes

Answer: A

Explanation:
= The command docker inspect nodes will not list all nodes in a swarm cluster from the command line. This command is invalid, as docker inspect requires one or more object names or IDs as arguments1. To list all nodes in a swarm cluster, you need to use the docker node ls command from a manager node2. This command will display the ID, hostname, status, availability, manager status, and engine version of each node in the swarm2. You can also use the -f or --filter flag to filter the nodes by various criteria, such as role, label, or name2. Reference:
1: docker inspect | Docker Docs
2: docker node ls | Docker Docs
