Here are the answers to Wednesday's CCNA, CCNP, and Network+ practice exam questions!
CCNA:
In OSPF, what is true of the term "Area 0"?
A. This is the backbone of an OSPF deployment.
B. All other areas must contain a router with a physical or logical interface in Area 0.
C. A router must have all interfaces in Area 0, or none.
D. Area 0 cannot be a stub area, but it can be a total stub area.
E. Area 0 cannot be a total stub area, but it can be a stub area.
F. Area 0 cannot be a stub or a total stub area.
Answers: A, B, F. Area 0 is the backbone of an OSPF network, every other area must contain a router with a physical or logical interface (virtual link) in Area 0, and you can't make Area 0 a stub or total stub area.
Network+ :
On what network device would you configure a Virtual LAN?
A. hub
B. repeater
C. switch
D. router
E. gateway
Answer: C. Virtual LANs (VLANs) are configured on switches.
CCNP / BSCI:
After EIGRP route summarization is configured, the router on which summarization is configured will have an extra route. To what interface or destination does this new route point?
A. The loopback interface
B. The interface with the EIGRP RID
C. The exit interface to use to reach the summarized routes
D. The null0 interface
E. The remote IP address to use to reach the summarized routes
Answer: D. To prevent routing loops, a route to the null interface will appear in the routing table of the router performing the summarization. Packets destined for one of the routes being summarized will match one of the more-specific routes in the table, while packets matching the summary route but not one of the more-specific routes will be sent to null0 - dropped.
CCNP / BCRAN:
Which of the following status codes indicate that the DLCI is known and that connectivity exists via that DLCI?
A. 0x0
B. 0x2
C. 0x3
D. 0x4
Answer: B. 0x0 indicates that the switch knows of the DLCI, but it's not usable.
0x2 indicates that the DLCI is known and that connectivity exists via that DLCI.
0x3 indicates that the DLCI exists but congestion is present.
0x4 indicates the switch knew about the DLCI in the past, but it is now deleted.
CCNP / BCMSN:
In what two fashions can a switch learn MAC addresses?
A. static configurations
B. by examining source MAC addresses of incoming frames
C. by examining destination MAC addresses of incoming frames
D. VMPS server broadcasts
Answers: A, B.
CCNP / CIT:
You're configuring Dialer Watch and three different routes are being watched. Which of the following is true?
A. Only one of the watched routes needs to leave the routing table in order for the ISDN link to come up.
B. All of the watched routes need to leave the routing table in order for the ISDN link to come up.
C. Additional dialer map statements will be needed.
D. Besides a route or routes leaving the routing table, nothing else needs to happen for the ISDN link to come up in Dialer Watch.
E. Dialer Watch is dependent on interesting traffic to bring the ISDN link up.
Answers: A, C, D. Only one of the watched routes needs to drop from the routing table in order for Dialer Watch to bring the link up. Additional dialer map statements are needed, one for each watched route. Dialer Watch is not dependent on interesting traffic to bring the ISDN link up.
