The benefit in Obtaining the CNCF Certified Kubernetes Application Developer

As CKA is linked with KCSP, being CKA certified also opens doors in your career. It can also help you gain an advantage in the hiring process of some organisations. I’ve seen a few organisations mandating the certification, and in that scenario, it would be helpful for you to quickly get within the shortlisted candidates.

At least in the course of preparing for these certifications, you will learn the core of Kubernetes and would appreciate what it can and cannot do. You will also understand what resources you can use in what kind of situations. And while you pass this certification and prepare for the next bit, Kubernetes concepts would be very natural for you.

You can also use certifications to validate your knowledge. It helps you understand what you know about the subject and also address some of the gaps or aspects of the tool you were missing. It also allows you to understand best practices and utilities.

Answer: A

NEW QUESTION 16
Exhibit:

Given a container that writes a log file in format A and a container that converts log files from format A to format B, create a deployment that runs both containers such that the log files from the first container are converted by the second container, emitting logs in format B.
Task:
* Create a deployment named deployment-xyz in the default namespace, that:
* Includes a primary
lfccncf/busybox:1 container, named logger-dev
* includes a sidecar Ifccncf/fluentd:v0.12 container, named adapter-zen
* Mounts a shared volume /tmp/log on both containers, which does not persist when the pod is deleted
* Instructs the logger-dev
container to run the command

which should output logs to /tmp/log/input.log in plain text format, with example values:

* The adapter-zen sidecar container should read /tmp/log/input.log and output the data to /tmp/log/output.* in Fluentd JSON format. Note that no knowledge of Fluentd is required to complete this task: all you will need to achieve this is to create the ConfigMap from the spec file provided at /opt/KDMC00102/fluentd-configma p.yaml , and mount that ConfigMap to /fluentd/etc in the adapter-zen sidecar container
