Here are the answers to Thursday's CCNA, CCNP, and Network+ exam questions!
CCNA:
A router running RIP detects a down network. What action will it take?
A. None.
B. The router will advertise the route with a metric of 16.
C. The router will immediately stop advertising the route.
D. The router will advertise the route with a metric of 255.
Answer: B. This is necessary due to the slow convergence of RIP, and is called route poisoning.
Network+ :
Which of the following devices are specifically designed to prevent or lessen attenuation?
A. hub
B. router
C. switch
D. repeater
E. bridge
Answer: A, D. Repeaters and hubs (which are basically multiport repeaters) help to lessen the effects of attenuation, the gradual weakening of an electric signal as it travels along a cable.
CCNP / BSCI:
Short answer: What BGP attribute's possible values are ?, i , and e ?
Answer: Those are the three possible values of the Origin code. A lower-case i indicates an internal BGP route, a lower-case e indicates an eBGP route, and the question mark means the route's true origin is unknown. That usually means the route was learned via redistribution.
CCNP / BCRAN:
Short answer: Name the PRI framing types.
Answer: The PRI framing types are Super Frame (SF), Extended Super Frame (ESF), and Cyclic Redundancy Check 4 (CRC4). SF is the default.
CCNP / BCMSN:
In an Etherchannel, what mathematical operation decides the physical channel that will actually carry the data from a particular source to a particular destination?
A. AND
B. OR
C. XOR
D. BOOLEAN
Answer: C.
CCNP / CIT:
Which of the following show you the number of matches made against ACLs running on the router?
A. show ip access-list
B. show acl match
C. show list matching
D. show access-list
Answers: A, D. Both of those commands will give you the desired information.
See you later this morning with a new batch of CCNA, CCNP, and Network+ questions, along with the answers to Friday's questions!
