NEW QUESTION # 186
Two development teams in your organization use Kubernetes and want to deploy their applications while ensuring that Kubernetes-specific resources, such as secrets, are grouped together for each application.
Is this a way to accomplish this?
Solution: Create one pod and add all the resources needed for each application
Answer: A
Explanation:
Creating one pod and adding all the resources needed for each application is not a good way to accomplish the goal of grouping Kubernetes-specific resources for each application. This is because pods are the smallest unit of a Kubernetes application, and they are designed to run a single container or a set of tightly coupled containers that share the same network and storage resources1. Pods are ephemeral and can be created and destroyed by the Kubernetes system at any time. Therefore, putting multiple applications in one pod would make them harder to manage, scale, and update independently. A better way to accomplish the goal is to use namespaces, which are logical clusters within a physical cluster that can isolate resources, policies, and configurations for different applications2. Namespaces can also help organize secrets, which are Kubernetes objects that store sensitive information such as passwords, tokens, and keys3. References:
* Pods | Kubernetes
* Namespaces | Kubernetes

NEW QUESTION # 190
Will this command list all nodes in a swarm cluster from the command line?
Solution. 'docker inspect nodes
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:

2: docker node ls | Docker Docs
