Thanks for the +1s on Google -- I really appreciate it!  : ) 

Your CCNA and CCENT Training Post for Tuesday, October 29 is here...

.. and for new CCNP SWITCH, TSHOOT, and ROUTE Training Posts, scroll down to the next few posts!

Let's get to today's exam!

1.   If you wanted to make a static route less believable than a matching route discovered by OSPF, what metric would you change?

A.  None, because you can't do this.

B.  The OSPF cost.

C.  The administrative distance.

D.  The bandwidth value on the local router's exit interface.

E.  The delay value on the interface the packets will exit on the local router to reach their destination.

2.  Name the two major trunking protocols that will run across a Cisco switch trunk.

Hint: One's Cisco-proprietary, the other is not, and you better know which is which. : ) 

3.   What term describes the state of a protocol when routes have been calculated and agreements have been made as to adjacencies?

4.   In the command ip nat inside source list 5, what does the "5" refer to?

A.  The VLAN used by the NAT hosts.

B.  The ACL that identifies the inside hosts that can use NAT.

C.  The number of addresses in the NAT pool.

D.  The number of minutes to which the NAT idle timer is set.

E.  The ACL that identifies the remote destinations to which NAT will allow communication by the inside hosts, which are identified by the "ip nat inside" command.

And now... the answers!

1.  "C".  You can change the admin distance of a static route to make it enter the routing table only if the dynamic routing protocol's route disappears from the table, which is really what we'd be doing here.  This is a floating static route.

2.  Our Cisco-proprietary trunking protocol is ISL, and the non-proprietary protocol is IEEE 802.1q ("dot1q").

3.   You might think the answer is nirvana, but it's actually convergence.

4.  "B".  The number refers to the ACL that identifies the inside hosts and network segments that can be "natted out".  As opposed to "ratted out".  : ) 

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