Frequently Asked Questions (FAQs)

  • Why get Red Hat certified?

    Red Hat certifications are highly respected in the IT industry and validate your expertise in open source technologies, particularly Red Hat Enterprise Linux (RHEL) and Red Hat OpenShift.

    These certifications demonstrate your ability to design, deploy, and manage complex enterprise environments using Red Hat solutions, increasing your value to employers and opening doors to a wide range of career opportunities.

  • What to expect for the examination?

    Red Hat certification exams are performance-based, meaning you'll be evaluated on your ability to perform real-world tasks in a live environment.

    This ensures that you not only understand the theoretical concepts but also have the practical skills to apply them.

    Note: Certification requirements and policies may be updated by Red Hat from time to time. We apologize for any discrepancies; do get in touch with us if you have any questions.

  • How long is Red Hat certification valid for?

    Red Hat certifications are current for three years.

    According to Red Hat, these certifications do not “expire”, or become “terminated” or “invalid”, but they can become “non-current”.

    There are different ways to keep a certification current, depending on the type of certification. You always have the option of retaking an exam to renew its associated certification.

    In some instances, you can earn other certifications to keep your certification current. This approach allows IT professionals to expand their skills and knowledge into new areas, which is increasingly important for a successful IT career.
