In the latest version of Connecting Networks, we lost frame relay but was not replaced with anything. Yes, PPPoE was added but with this is not considered as a replacement for a shared WAN technology, and had limited applications. I would like to suggest that we add either Metro Ethernet or MPLS to Connecting networks. To address the concern some may have regarding alignment of the Netacad course materials to those of the CCNA industry certification, the related labs can be marked as optional.

Thank you.
