Cisco CCNA mock exam questions sample test – Question 188

Examine the following partial output of the show interfaces command.
188
Which of the following statements are true? (Choose all that apply.)

A. the interface is functional
B. the largest frame allowed through this connection is 1500 bytes
C. the interface needs the no shutdown command executed to be functional
D. the largest frame allowed through this connection is 10000 Kbs

Correct Answer: BC

Explanation:
From this output, we can determine that the largest frame allowed through this connection is 1500 bytes and that the interface needs the no shutdown command executed to be functional. The portions of the output that tell us this are:
MTU 1500 bytes indicates that the Maximum Transmission Unit (MTU) is 1500 bytes. The MTU is the largest frame size allowed.
Ethernet0/0 is administratively down indicates that the interface has either been disabled or has never been enabled. The command no shutdown is used to enable an interface, and until enabled, it will not function.
The interface is not functional, as indicated by the Ethernet0/0 is administratively down portion of the output.
The largest frame allowed through this connection is not 10000 Kbs. It is 1500 bytes. It is interesting to note that the bandwidth of the connection is 10000 Kbs, as indicated by the section:
BW 10000 Kbit
