Q31IP Connectivity
Refer to the exhibit. An administrator receives a call from a branch office about poor application performance for an application hosted at the headquarters. Ethernet 1 is connected between Router1 and the LAN switch. What identifies the issue?

Isn't duplex mismatch a better choice because of the high # of collisions?
B 9
Selected Answer: B
C is clearly wrong because if that were the case, we'd see output drops and there are zero output drops.
B 6
Selected Answer: B
The output shows 15000 collisions on the interface, which indicates a duplex mismatch issue between Router1 and the switch. Therefore, the correct answer is B.
B 6
Selected Answer: B
The output queue is 0/40 and there are no total output drops, so the link is not over-utilized. That rules out D. The queueing strategy is RED and the absence of drops rules out C. The default MTU size is 1500 bytes, which rules out A. That leaves B. If there was still any doubt, the huge amount of collisions can't be caused by D or C, but can absolutely be caused by B, a duplex mismatch. It's 100% B.
B 3
Selected Answer: B
'There is a duplex mismatch. ' sounds better to me, so "B".
B 3
Selected Answer: B
There are many collisions and the interface is configured to 10 Mbps.
D 2
Selected Answer: D
The interface shows a lot of traffic, it is the only one that makes sense

Hardware in Lance: La operacion normal de este tipo de hardware es Half Duplex.
El contador 179 deferred se incrementa cuando hay interrupcion en el envio de data porque el otro extremo esta full duplex y hay mismatch in the negociacion.

This is B
Output errors: Output errors show errors, like collisions, during the transmission of a frame. In most Ethernet-based networks, full-duplex transmission is the norm, and half-duplex transmission is the exception. In full-duplex transmission, collisions cannot happen. Therefore, collisions, especially late collisions, often point to duplex mismatches.
