Examine the following partial output of the show interfaces command.
Router# show interfaces ethernet 0/0
Ethernet0/0 is administratively down, line protocol is down
Hardware is AmdP2, address is 0003.e39b.9220 (bia 0003.e39b.9220)
Internet address is 10.1.0.254/16
MTU 1500 bytes, BW 10000 Kbit, DLY 1000 usec,
reliability 255/255, txload 1/255, rxload 1/255
Encapsulation ARPA, loopback not set
Keepalive set (10 sec)
ARP type: ARPA, ARP Timeout 04:00:00
<Output omitted>
Which of the following statements are true?
| 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 |
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
