Layer 2 WAN Technology

What are the most common Layer 2 WAN technologies? Also, what Cisco certification will be of most help regarding this technology?

Frame-relay followed by ATM. All cisco router certifications contains elements of these in varying amounts.

I have not seen ATM in the CCNA curriculum.

Hi Ray,

You won't found ATM in any of the current Cisco exams (except for the CCIE SP and a little bit in the CCIP MPLS exam), but you'll find frame-relay in CCNA, CCNP, and even CCIE R&S, formerly there was a CCNP exam called Remote Access, but it has retired and i believe that it was replaced with this one:

Implementing Secure Converged Wide Area Networks

http://www.cisco.com/web/learning/le3/current_exams/642-825.html

which covers MPLS and other stuff (some ATM and some FR), please take a look at it.

HTH,
