Welcome! Here are the answers to yesterday's Cisco practice exam questions!

CCNA Certification:

What effect does the following configuration have ?

R2#conf t
R2(config)#int s0
R2(config-if)#bandwidth 512

A. The IGRP route calculations will be changed from the default.

B. The RIP route calculations will be changed from the default.

C. The EIGRP route calculations will be changed from the default.

D. Static routing metrics will be changed from the default.

Answers: A, C. Both IGRP and EIGRP route calculations use the bandwidth (and delay) values by default, so changing either will affect the metrics for both of those protocols.

CCNP Certification / BSCI Exam:

Short answer: A routing table has three routes to a remote destination. The router codes for the three routes are "I", "D", and "D EX". According to their administrative distance, what is the order of trustworthiness of these routes, from best to worst?

Answer: From best to worst - and with administrative distance, that means lowest to highest - the order is "D" (EIGRP, AD 90), "I" (IGRP, AD 100), "D EX" (External EIGRP, AD 170).

CCNP Certification / BCMSN Exam:

Short answer: A VTP Client has lost some or all of the contents of its VTP database. What VTP advertisement will it send to retrieve this information?

Answer: The client will send an aptly-named Client Advertisement Request.

CCNP Certification / ISCW Exam:

Identify the true statements regarding CQ.

A, There are four predefined queues.

B. There are 17 predefined queues.

C. All queues can be configured to carry voice and data.

D. At least one queue is reserved for network control traffic.

E. Each queue has a default limit of 20 packets.

Answers: B, D, E. Of CQ's 17 predefined queues, Queue Zero is reserved for network control traffic such as routing protocol Hellos and Syslog messages. CQ uses round-robin transmission, and each queue has a limit of 20 packets.
