Question 1

Which networking certification should I start with?

Accepted Answer

Most engineers start with CompTIA Network+ for vendor-neutral fundamentals, then Cisco CCNA for the most widely recognized associate-level networking certification. From there you can pursue CCNP and specialize.

Question 2

Do networking certifications expire?

Accepted Answer

Yes — most do. CompTIA and Cisco certifications are typically valid for three years and must be renewed through continuing education or by passing a current exam.
