Here are the answers to Thursday night's Cisco CCNA and CCNP practice questions!

The CCNA and CCNP CIT question comes first - because they're the same question!

CCNA / CCNP CIT:

Examine the following router-on-a-stick configuration and identify the true statements.

interface fast 1/0
no ip address

interface fast 1/0.20
ip address 100.1.1.1 255.255.255.0
encapsulation dot1q 10

interface fast 1/0.10
ip address 200.1.1.1 255.255.255.0
encapsulation dot1q 20

A. The trunking protocol in use is the industry standard.

B. The trunking protocol in use is Cisco-proprietary.

C. Hosts in VLAN 20 should use 200.1.1.1 as their default gateway.

D. Hosts in VLAN 20 should use 100.1.1.1 as their default gateway.

E. The switch between the hosts and this router can be a 2950.

F. The switch between the hosts and this router cannot be a 2950.

Answer: A, C, F. Dot1q is the industry standard trunking protocol, while ISL is Cisco-proprietary. The statement encapsulation dot1q 20 under the subinterface with the IP address 200.1.1.1 indicates that VLAN 20 will be using this interface as its default gateway. And finally, since dot1q is in use, the switch could be a 2950; 2950 switches do not run ISL, so if the router were configured for ISL, the configuration would be invalid.

CCNP / BSCI:

Identify the metrics for Cisco's version of ISIS.

A. cost

B. delay

C. expense

D. error

E. default

Answer: A, E. The only ISIS metric Cisco supports is "cost" (also referred to as "default"), it is 10 by default for all links regardless of interface speed, and is configurable.


CCNP / BCRAN:

You're in privileged exec mode. What number privilege level do you have? Short answer, no choices given.

Answer: Privilege level 15, the highest level.


CCNP / BCMSN:

How often are VTP Summary Advertisements sent by a VTP Server?

A. Every 5 minutes.

B. Every 5 minutes or upon a change in the VLAN database.

C. Upon a change in the VLAN database only.

D. Upon a reload.

Answer: B. Summary Ads are sent every 5 minutes or upon a change in the VLAN database.


See you in just a few minutes with Saturday morning's Cisco CCNA and CCNP practice questions!
