Here are the answers to the Cisco training questions posted on Monday, June 2. CCENT questions return later today, and Network+ questions return in July!

Be sure to scroll down in the blog for the link to 10 brand-new CCNA Frame Relay practice questions!

CCNA Certification Exam:

The full command to configure OSPF Area 23 in the below configuration as a total stub area is ____________ .

R3#conf t
Enter configuration commands, one per line. End with CNTL/Z.
R3(config)#router ospf 1
R3(config-router)#

Answer: area 23 stub no-summary. If you leave the "no-summary" off, area 23 is configured as stub, not total stub.


CCNP Certification / BSCI Exam:

A. The cost of the path from the local router to the ASBR.

B. The cost of the path from the local router to the destination network.

C. The cost of the path from the ASBR to the destination network.

D. The cost of the path from the local router to the ABR.

Answer: B. OSPF E1 routes are learned originally by redistribution, and include the entire cost of the path from the local router to the destination network. The default is E2, where only the cost of the path from the ASBR to the destination network is reflected in the cost.



CCNP Certification / BCMSN Exam:

Short answer: What interface-level command configures a multilayer switch port as a routed port?

Answer: no switchport. To configure the port back to its default setting, use switchport.



CCNP Certification / ISCW Exam:

Installing an unauthorized packet sniffer on a network falls into what category of network attack?

A. access

B. DoS

C. CoS

D. reconnaissance

E. middle

Answer: D. The use of an unauthorized packet sniffer is a reconnaissance attack.




CCNP Certification / ONT Exam:

Short answer: Name the three types of traffic marking performed by Frame Relay, and briefly describe each.

Answer: The Backward Explicit Congestion Notification (BECN) bit indicates whether congestion was encountered in the reverse direction the frame was traveling.

The Forward Explicit Congestion Notification (FECN) bit indicates that congestion was encountered in the same direction in which the frame was traveling.

The Discard Eligible (DE) bit indicates a frame of lower priority, and frames with the DE bit set will be dropped before bits that do not have that bit set.


New questions posted later today!
