Time for your CCNA practice exam questions for Tuesday, May 7!

Be sure to scroll down in the blog for a new set of CCENT questions, and let's get right to it!

1.  You send a ping and get the unusual result of "U.U.U".    Which of the following is the most likely culprit?

A.  The local router has a routing table entry for the pinged address, but a downstream router does not.

B.  The local router's default route is pointing at a closed interface.

C.  The packets aren't leaving the router.

D.  There's an ACL on the local router blocking the packets.

2.  Nothing's worse than sending an extended ping or traceroute and not knowing how to cancel it -- especially when someone else is there.   

What's the keystroke(s) that will stop your extended ping / traceroute in its tracks?

3.  Of the following, which does the ip route command require you to configure?

A.  The source network / host

B.  The destination network / host

C.  Network mask / subnet mask

D.  Wildcard mask

E.  Administrative Distance

F.  IP protocol number

The answers right after this brief, important message!

I guarantee you'll beat the Sept. 2013 CCNA and CCENT exam version changeover with my $44 Video Boot Camp, just as over 3500 students are doing right now....

... and if you don't earn your CCNA before September, no worry, because you'll have free access to my CCNA 200-120 Video Boot Camp videos!

And now... the answers!

1.  (A).  U.U.U indicates that the packets are leaving the local router, but a downstream router doesn't know what to do with them.

2.  Stop pings of any kind along with traceroutes using the ctrl-shift-6 keystroke.  

3.  (B, C).  Obviously you'll need to define a destination, and you'll need a network/subnet mask as well.  The administrative distance can be configured, as you'll see in one of the videos below, but it's optional. 

Let's get to today's videos from my CCNA YouTube Channel, and I'll see you on YouTube and Udemy!

Today's videos are the three parts of a floating static route Video Boot Camp I did on YouTube a while back - it's still great study material, so let's hit it!
