  1. Hi Kiran,

    Did you complete this CKA exam? How did you prepare? How and where you did practice? Where to get practice questions?

  2. Hi Ravi

    I am preparing for Docker and Kubernetes administration course. Will it help to shift my career path and also will it help to increase my yearly earnings?

    1. Hello Rohit,
      Certifications may / may not directly guarantee an increase in yearly earnings. They are a structured path to develop yourself in any tech.
      You will earn well if you do well. And to do well, you need to be well-equipped. Certifications are a conduit to that.
