Here are the answers to the Cisco training questions posted Thursday, August 7!

Be sure to read today and yesterday's blog posts for more free Cisco practice exams and fully-illustrated tutorials that have been posted on the main site!

CCNA Certification And CCENT Certification:

In the following SDM screen shot from my CCNA / CCENT Study Guide, which button would I click to begin a NAT configuration?

Answer: Thought this was a trick question, right? :) Just click the "NAT" button and you're on your way!

CCNA Security Certification / CCNP ISCW Exam:

What is the Cisco IOS Resilient Configuration, and what is its purpose?

Answer: The Cisco IOS Resilient Configuration is a relatively new feature - it was introduced in 12.3(8)T - but it's a vital tool to have in case your Cisco routers are hit by an attack.

A Cisco router running this feature will both secure and maintain a copy of the starting configuration and the IOS image. Cisco's website states that these copies (the primary bootset) can't be erased by a user.

The commands are straightforward:

HQ(config)#secure ?
boot-config Archive the startup configuration
boot-image Secure the running image

As usual, there are restrictions on this feature that Cisco would like you to know before using this feature on a production router. You can quickly find that additional information via your favorite search engine.

CCNP Certification / BSCI Exam:

What's the major difference between an O E2 OSPF route and an O E1 OSPF route?

Answer: Both are routes learned by OSPF via route redistribution. The difference between E2 and E1 routes is that the metric of an E2 route only reflects the cost of the path between the ASBR and the final destination.

The metric of an E1 route reflects the OSPF cost of the entire path from the local router to the final destination.

CCNP Certification / BCMSN Exam:

Identify the true statements regarding a multilayer switch.

A. L3 routing is enabled by default.

B. L2 switching is enabled by default.

C. The VLAN 1 interface exists by default.

D. A default SVI is present on all multilayer switches.

Answer: B, C. You have to enable L3 routing on a multilayer switch, and you have to create your own SVIs.

CCNP / ONT Exam:

Identify the true statements regarding QoS preclassification.

A. With GRE, the pre-classify command is configured on the tunnel interface.

B. With GRE, the pre-classify command is configured in the crypto map.

C. With IPSec, the pre-classify command is configured on the tunnel interface.

D. With IPSec, the pre-classify command is configured in the crypto map.

Answers: A, D. If you're using GRE, use this command on the tunnel interface. IPSec configurations will have this command in the crypto map itself.

More questions here on the blog and on the main site later today!

To your success,
