CCNA And CCENT Flash Card Practice Exam:

Name The Command!

By Chris Bryant, CCIE #12933

We're going to take a slightly different angle on this CCNA practice exam...

... I'm going to show you a partial or full output of a Cisco router command, and you have to identify the command.

And you really have to know the command, because I'm not giving you any choices on this exam!

I post several of these a week on my CCNA Practice Exam page, so visit often, and let's get started with today's exam!

Command 1:

BRYANT_ADV_1#
HD unit 1, idb = 0xC0400, driver structure at 0xC5188
buffer size 1524 HD unit 1, No cable
cpb = 0xE2, eda = 0x3140, cda = 0x3000
RX ring with 16 entries at 0xE23000

Command 2:

R1#
Serial0 (up): ip 172.12.123.2 dlci 122(0x7A,0x1CA0), static, broadcast, CISCO, status defined, active

Serial0 (up): ip 172.12.123.3 dlci 123(0x7B,0x1CB0), static, broadcast, CISCO, status defined, active

Command 3:

Extra credit for identifying every column value. : )

172.12.123.3 0 FULL/DROTHER 00:01:55 172.12.123.3 Serial0
172.12.123.2 0 FULL/DROTHER 00:01:43 172.12.123.2 Serial0

Command 4:

2.0.0.0/32 is subnetted, 1 subnets
O IA 2.2.2.2 [110/65] via 172.12.123.2, 2w4d, Serial0
3.0.0.0/32 is subnetted, 1 subnets
O IA 3.3.3.3 [110/65] via 172.12.123.3, 2w4d, Serial0

Command 5 - Two possible answers on this one.

Routing Process "ospf 1" with ID 1.1.1.1
Supports only single TOS(TOS0) routes
Supports opaque LSA
It is an area border and autonomous system boundary router
Redistributing External Routes from,
connected, includes subnets in redistribution
rip, includes subnets in redistribution

And now -- the answers!

1. The command is show controller serial. I cut out a lot of the output that's not important to us - generally, we run this command to see which end of the DTE/DCE cable is connected to our local router.

Or in this case, to see there is no cable!

2. That's the output of show frame map.

Remember -- local DLCI, remote IP! ;)

 

3. That's the output of show ip ospf neighbor, and from left to right, you're looking at...

172.12.123.3 0 FULL/DROTHER 00:01:55 172.12.123.3 Serial0
172.12.123.2 0 FULL/DROTHER 00:01:43 172.12.123.2 Serial0

The neighbor ID

The remote router's OSPF interface priority

The adjacency state and the role of the neighbor

Dead Time (duh)

IP address of the remote router's interface

The name of the local interface through which the adjacency is formed

 

4. That's the output of show ip route ospf. If it were just show ip route, you'd see at least one connected route in there.

 

5. This info is at the top of the output of show ip protocols and show ip ospf.
