Hi Group!

Here are the answers to last Tuesday's practice exam questions!

When you're done tackling these, be sure to scroll down in the blog for more CCNA and CCNP training questions, new CCNA and Network+ videos, and much more - I've posted several new videos over the last few days and more are on the way!

CCNA / CCENT Certification:

Which of the following describes a link-state protocol?

A. Full routing tables multicast after fixed duration

B. Partial routing tables multicast after a certain amount of time

C. Strictly a broadcast protocol standard

D. Cisco-proprietary protocol scheme

E. None of these

Answer: E. None of them. Link-state protocols don't send routing tables, they're not strictly broadcasts, and non-Cisco routers can run them.

CCNA Security:

Which of the following describes a port's default setting as a result of the switch running DHCP Snooping?

A. trusted

B. untrusted

C. err-disabled

D. admin shutdown in effect

E. enabled with Backbonefast

Answer: B. The ports are untrusted by default.

BSCI Exam:

Short answer: Briefly describe what makes an OSPF router a "DROTHER".

Answer: If an OSPF-speaking router is neither a DR nor a BDR for a given segment, it's a "DROTHER" - "other than a DR", if you will.


Identify the true statements.

A. ISL is Cisco-proprietary.

B. Dot1q is Cisco-proprietary.

C. ISL is an industry-standard trunking protocol.

D. Dot1q is the industry-standard trunking protocol.

E. Generally, dot1q has higher overhead than ISL.

F. ISL usually results in more overhead than dot1q.

Answer: A, D, F. ISL is Cisco-proprietary, dot1q is the industry standard, and ISL has a higher overhead due to its default behavior of encapsulating every frame before sending them across the trunk.

ISCW Exam:

Between RADIUS and TACACS+, which must be enabled with the aaa new-model command?

A. Both

B. Neither

C. RADIUS only

D. TACACS+ only

Answer: A. They certainly have major differences, but one similarity is that they both require the aaa new-model command.

ONT Exam:

Short answer: What interface-level command enables WFQ?

Answer: fair-queue.
