Let's catch up on the answers to last Friday's Cisco practice exam questions!

CCNA Certification And CCENT Certification:

Where does a Cisco router store its starting configuration?

Is the running configuration in the same location? If not, where is the running config kept?

Answer: The starting config is kept in NVRAM; the running config in RAM. For that reason, the starting configuration is retained on a reload and the running configuration is not.

CCNA Security Certification / CCNP ISCW Exam:

As the term relates to network security, what is "SALT", and what service or protocol is made stronger by this process?

Answer: SALT is a way to make an MD5-encrypted password more secure. Here's a link to Wikipedia's SALT page for (much) more information:

CCNP Certification / BSCI Exam:

Consider the following NSEL address.


Identify the NSEL, the System ID, and the Area ID.

Answer: In a NET address such as 49.0001.1223.1213.1233.00, the “00” is the NSEL field. The six bytes next to that are the System ID. The remaining value is the Area ID.

00 = NSEL

1234.1234.1233 = System ID

49.0001 = Area ID. (Not all Area IDs are this length!)

CCNP Certification / BCMSN Exam:

Name the three major types of VTP advertisements.

Answer: Summary, Subset, and Client Advertisement Requests.

CCNP / ONT Exam:

You're in the QoS Policy Generation screen in SDM. How many QoS classes will SDM create to handle VoIP and voice signaling traffic?

Answer: Two.

New questions posted later today!

To your success,

Chris Bryant
