And now... the answers!

1.  "B". With ROAS, you're going to create subinterfaces on the router, and the IP addresses will be configured on those subinterfaces.

2.  "D".  The hosts should use the IP addresses on the subinterfaces as their default gateway.

3.   The summary is /13, which can also be expressed as

Going from left to right, the first two octets look like this:   00001010  00000001   00001010  00000010   00001010  00000011   00001010  00000100

The summary ends where the routes being summarized no longer have a bit in common.  That happens after 13 bits, where the top three routes have a 0 and the bottom route has a 1. 

That's your summary route, and the summary mask is the number of bits in common.  That's it!

4.  To switch from the default of HDLC to PPP, use the encapsulation ppp command. (On both ends of the connection, of course!)

Thanks for taking today's practice exam, and I'll see you on YouTube and Udemy!
