Which route does R1 select for traffic that is destined to 192 168.16.2?
Correct Answer:
D
The destination IP addresses match all four entries in the routing table but the 192.168.16.0/27 has the longest prefix so it will be chosen. This is called the “longest prefix match” rule.

A frame that enters a switch fails the Frame Check Sequence. Which two interface counters are incremented? (Choose two)
Correct Answer:
DE
Whenever the physical transmission has problems, the receiving device might receive a frame whose bits have changed values. These frames do not pass the error detection logic as implemented in the FCS field in the Ethernet trailer. The receiving device discards the frame and counts it as some kind of input error.
Cisco switches list this error as a CRC error. Cyclic redundancy check (CRC) is a term related to how the FCS math detects an error.
The “input errors” includes runts, giants, no buffer, CRC, frame, overrun, and ignored counts.
The output below show the interface counters with the “show interface s0/0/0” command:
