You are a network administrator and you need to access the secure command line interface access of an edge router on your network. The router uses cryptography for remote authentication. Which protocol is the router configured with for this purpose?

The router is configured with PAT.

It is important to note that PAT stands for Port Address Translation which is an extension to network address translation (NAT) which allows several devices(computers or other electronic devices) on a local area network (LAN) to be connected(mapped) to a single public IP address. The main purpose of PAT is to conserve IP addresses.
