Here are the answers to Monday's Cisco and CompTIA certification exam practice questions!
CCNA:
EIGRP has is considered a hybrid protocol. Why?
A. EIGRP has characteristics of RIP and IGRP.
B. EIGRP has characteristics of link state and distance vector protocols.
C. EIGRP has characteristics of OSPF and ISIS.
D. EIGRP is a combination of IGRP and ISIS.
Answer: B. EIGRP is considered a hybrid because it combines characteristics of both link state and distance vector protocols.
Network+ :
What is indicated by a destination MAC address of "ff-ff-ff-ff-ff-ff"?
A. The message is a layer 2 broadcast.
B. The message is a layer 3 broadcast.
C. The message is a layer 2 multicast.
D. The message is a layer 3 multicast.
E. The message is a layer 2 unicast.
F. The message is a layer 3 unicast.
Answer: A. The "all-Fs" MAC destination address is a layer 2 broadcast.
CCNP / BSCI:
If a router receives a BGP update and sees its own AS number in the update, what action is taken?
A. The update is accepted unconditionally.
B. The update is accepted if the sequence number is higher than the one the router already has.
C. The update is accepted if the sequence number is lower than the one the router already has.
D. The update is discarded.
Answer: D. If a router sees its own AS number in the AS_PATH contained in a BGP update, the router will discard the update to avoid the creation of a routing loop.
CCNP / BCMSN:
Identify the true statements regarding CoS.
A. It's a Layer 2 value.
B. It's a Layer 3 value.
C. It can be assigned as data is switched from one port to another on the same switch.
D. It can be assigned as frames are sent across a trunk.
Answers: A, D. It is an L2 value, and can be assigned as frames are sent across a trunk.
CCNP / BCRAN:
Which of the following values can be set with the "frame-relay traffic-rate" command?
A. EIR
B. DE
C. Peak
D. CIR
Answer: C, D. CIR and Peak are set. Peak is the sum of the CIR and EIR, but the EIR is not expressly configured.
CCNP / CIT:
You're trying to get Layer Two running on a BRI interface. Which of the following messages are you hoping to see?
A. ISDN_STATUS_OK, shown by "debug isdn q921"
B. MULTIPLE_FRAME_ESTABLISHED, shown by "show isdn status"
C. ISDN_STATUS_OK, shown by "show isdn status"
D. MULTIPLE_FRAME_ESTABLISHED, shown by "debug isdn q921"
Answer: C. You want to run show isdn status and see MULTIPLE_FRAME_ESTABLISHED, which means Layer 2 of your ISDN configuration is up and running.
