What is the bandwidth on the WAN interface of Router 1?

A.
16 Kbit/sec

B.
32 Kbit/sec

C.
64 Kbit/sec

D.
128 Kbit/sec

E.
512 Kbit/sec

F.
1544 Kbit/sec

Explanation:
Use the “show interface s0/0” to see the bandwidth set at 16 Kbit/sec.
The show interface s0/0 command results will look something like this and the bandwidth will
be represented by the “BW” on the fourth line as seen below where BW equals 1544 Kbits/sec.
R2#show interface serial 0/0
Serial0/0 is up, line protocol is down
Hardware is GT96K Serial
Internet address is 10.1.1.5/30
MTU 1500 bytes, BW 1544 Kbit/sec, DLY 20000 uses.
