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

CCNA Exam:

By default, what traffic resets the dialer idle-timeout value?

A. All traffic.

B. No traffic.

C. All interesting traffic.

D. All non-interesting traffic.

E. All IP traffic.

F. All traffic defined by the "dialer-list" command.

Answers: C, F. Interesting traffic resets the dialer idle-timer, and interesting traffic is that traffic defined by the "dialer-list" command.

CCNP Certification / BSCI Exam:

You've put multihoming into effect in your BGP AS. The router that is communicating with your ISPs is low on memory and CPU. What type of routes would it benefit your router to receive from the ISP?

A. Default routes only.

B. Default routes and some more-specific routes.

C. All normal, specific routes.

D. BGP routes only.

Answer: A. When your AS is multihoming, the router that is communicating with your ISP should have as much memory and CPU as possible. If that router happens to be low on these resources, the ISP should be sending this router default routes only, which have the lowest impact on CPU and memory.

If CPU and memory are not really a concern, your router should be getting the more-specific routes. There is a middle ground where your ISP could send a default route and some more-specific routes as well.

CCNP Certification / BCMSN Exam:

Which two of the following port types cannot be configured for a dynamic VLAN assignment?

A. Ports running port security.

B. Trunking-enabled ports

C. Access ports

D. Fast Ethernet ports

Answers: A, B. If a port is protected with port security, or is in any mode that would allow it to become a trunk, it cannot receive a VLAN membership dynamically.

CCNP Certification / ISCW Exam:

Short answer: What two numerical ranges are used by standard ACLs?

Answer: 1 - 99 and 1300 - 1399.

A. Traffic policing can only be applied to outbound traffic.

B. Traffic policing can only be applied to incoming traffic.
