Cisco And CompTIA Practice Questions: Etherchannels, The OSI Model, And More!

Prepare for CCNA, CCENT, CCNP, and Network+ exam success with these practice questions covering Etherchannels, the OSI model, static default routing, and more!

Here are some questions on static routing, the OSI model, IP version 6, and other topics to help prepare you for CCNA, CCENT, and CCNP certification exam success!   Network+ candidates,  I didn’t leave you out!

CCNA Certification:

What character or combination of characters indicates a statically configured default route?

Answer: An "S*" next to a route indicates that it is a default static route.  If there were no asterisk, the route type indicated would be a static route – but not a default static route.

CCENT Certification / Network+ Certification Question:

Which one of the following networking terms is not associated with the same OSI layer as the others?

A. router

B. packet

C. TCP

D. IP

Answer: C. TCP runs at the Transport layer of the OSI model. The other three terms are associated with the Network layer.  The Network layer is sometimes referred to as the “routing layer”.

CCNP Certification / BSCI Exam:

If an IPv6 address begins with "FF", what kind of address is it?

A. broadcast

B. unicast

C. anycast

D. multicast

Answer: D. Any IPv6 address beginning with "FF" is a multicast. IPv6 does not use broadcasts.

CCNP Certification / BCMSN Exam:

You've configured an Etherchannel and note that the trunk has gone down. You check the interfaces on one switch and note that two are "err-disabled". The corresponding ports on the other switch are not. What should you do?

A. Nothing - that's the normal and desired behavior.

B. Shut and reopen the err-disabled interfaces.

C. Shut and reopen the non-err-disabled interfaces.

D. Use the err-abled command on the err-disabled interfaces.

Answer: B. After finishing the config, shut and reopen the err-disabled interfaces. If the configuration is correct, that will do the trick.  This is common when you configure all of the ports on one switch and then start configuring the other switch, rather than going back and forth between the appropriate ports on the switches.

See you soon with more CCNA, Network+, CCNP, and CCENT questions!
