Welcome back!

Let's take a look at the answers to the Cisco practice exam questions posted here on Monday, September 22!

All of yesterday's questions were short answer.

CCNA Certification And CCENT Certification:

In the wonderful world of WANs, what is the "demarc point"?

Answer: That's the point where your network's wiring and equipment meet that of the service provider. It also makes for some interesting tech support discussions. ("No, sir, I'm quite sure the problem is on your side of the demarc point!")

CCNA Security Certification / CCNP ISCW Exam:

Just 34 days until the release of my CCNA Security Study Package!

What command resulted in the following output?

R1# ?
Session audit trail is disabled
Session alert is enabled
one-minute (sampling period) thresholds are [400:500] connections
max-incomplete sessions thresholds are [400:500]
max-incomplete tcp connections per host is 50. Block-time 0 minute.
tcp synwait-time is 30 sec -- tcp finwait-time is 5 sec
tcp idle-time is 3600 sec -- udp idle-time is 30 sec

Answer: That's the (very) partial output of the show ip inspect config command.

CCNP Certification / BSCI Exam:

In OSPF, Area 0 cannot be made into which of the following ?

A. stub

B. total stub

C. not-so-stub stub

D. partial stub

Answer: A, B, C, D. You can't configure Area 0 as any kind of stub area.

CCNP Certification / BCMSN Exam:

What global command will enable BPDU Guard on all ports on your Cisco switch?

Answer: SW1(config)#spanning-tree portfast bpduguard default

CCNP / ONT Exam:

Name three values commonly examined to determine the bandwidth of a VoIP call.

Answer: Any three of these six values would be correct: packet rate, packetization period, header overhead, L2 overhead, tunneling overhead (if you're tunneling, that is), and the CODEC in use.

More questions for you right here later today! Be sure to read today's other blog posts for my latest YouTube CCNA and CCNP certification videos!
