Question 1

Which networking certification should I start with?

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.

Do networking certifications expire?
