One scheduling detail: the RH253 exam is delivered Instructor-led training course (no standalone certification exam for RH253; knowledge supports RHCE track) — plan accordingly when you book.

The RH253 exam — officially the RedHat Linux Networking and Security Administration — is RedHat's certification test for professionals working with its technologies, and passing it earns the RHCE (legacy training track) certification at the Professional level. Because it is vendor-issued and skills-based, employers can compare candidates on it directly — that is what keeps it valuable. It also connects naturally to Red Hat Certified Engineer (RHCE).

Once you purchase, 365 days of free updates are included, and if the product expires, the update service renews at a 50% discount from your member zone.
