It's Sunday, November 3, and here's a bonus CCNA and CCENT Video Practice Exam for you!


I'll have all-new CCNA and CCNP exams posted Monday.  Right now, let's get to today's exam!



1. Short answer:  What administrative distance indicates a totally untrustworthy route source?







2.  Which of the following are legal options OR mandatory values in the ip route command?

A.  The IP address of the next-hop router

B.  The name of the local router's exit interface

C.  The name of the interface on the next-hop router

D.  The IP address of the local router's exit interface

E.  "broadcast"








3.   Which of the following describes IEEE 802.1q?

A.  Frames destined for the native VLAN are untagged.

B.  The native VLAN can be changed, but each end of the trunk must agree on the native VLAN or you'll receive error messages.

C.  Port security can run on dot1q trunks.

D.  This is a Cisco-proprietary trunking protocol.

And now... the answers!

1.  An admin distance of 255 indicates a totally untrustworthy routing source.


2.  "A, B".  At the end of the ip route command, you must specify either the name of the exit interface or the IP address of the next-hop router.   

You can't specify the name of the interface on the next-hop router or the local router's IP address, and there is no broadcast option with the ip route command -- that's an option with frame map.



3.  "A, B".   Frames destined for the native VLAN are untagged (further reducing overhead), and you can change the native VLAN.  You have to change it on both ends, though, or the switch will let you know about it!

You can't run port security on trunking ports, and dot1q is the industry standard trunking protocol.  (Another trunking protocol, ISL, is Cisco-proprietary.)

Thanks for taking today's practice exam, and I'll see you on YouTube and Udemy!
