Cisco CCNP certification exam: 642-901

Building Scalable Cisco InternetWorks (BSCI)

After you study your text books it is important to test your newly acquired knowledge and see just how well you have absorbed the material. Practice exams....


* Reinforces what you learnt - fill in the gaps of what you missed
* Gets you used to answering questions to build confidence and familiarity

Here are 10 Multiple choice exams questions for you to practice on:

______________________________

Question 1# - ABC.com uses EIGRP as the primary routing protocol in their network. How does EIGRP advertise subnet masks for each destination network?

A. EIGRP advertises a fixed length subnet mask for each destination network.

B. EIGRP advertises only a classful subnet mask for each destination network.

C. EIGRP, like IGRP and RIP, does not advertise a subnet mask for each destination network.

D. EIGRP advertises a prefix length for each destination network.

Question 2# - You need to configure EIGRP on a new ABC.com router. Which command should you issue first to configure EIGRP for IP?

A. router eigrp autonomous-system-number
B. ip eigrp autonomous-system-number
C. ip eigrp routing
D. router eigrp process-id

Question 3# - While performing a routine inspection of your OSPF network you come to the realization that the Designated Router (DR) may be overloaded, and you're considering changing the DR. What are three ways you could manipulate the election of the DR? (Select three)

A. Use of the priority command.
B. Use of the router-id command.
C. Assignment of the loopback address.
D. Assigning a lower IP address
E. By adding additional memory to the desired router.

Question 4# - When comparing OSPF and IS-IS, which three characteristics apply to IS-IS but not to OSPF? (Select three)

A. IS-IS encapsulates PDUs directly into a data-link frame

B. IS-IS uses a default IOS metric of 10 on each interface

C. IS-IS runs PRC (Partial Route Calculations) to calculate IP reachability information

D. IS-IS uses stubby areas to improve network scalability

E. IS-IS uses an on-demand circuit to reduce the hello and LSA flooding across switched WAN links, such as ISDN

F. IS-IS uses a DIS and a backup DIS to present the psuedo-node on the LAN

Question 5# - Your newly appointed ABC.com trainee wants to know why Level-3 area routing is not a supported feature of integrated IS-IS on Cisco routers. What will your reply be?

A. The system ID on a Cisco router is limited to 6 bytes.

B. The NET on a Cisco router is restricted to a maximum of 8 bytes.

C. The lack of a Domain portion of the NSAP only accommodates for 2 levels of routing hierarchy.

D. Cisco routers cannot route CLNS data that use the ISO/IEC 10589 standard of NSAP addressing.

E. Since the NSAP service identifier (N-SEL) must always be set to 00, no other service types are available.

Question 6# - Your network is running BGP as well as EIGRP. You are considering redistributing your BGP routes into your EIGRP. What factors must you consider before redistributing BGP routes to IGP?

A. IGPs are limited to 250 routes

B. A full BGP routing table may contain 100,000+ routes

C. Because of possible routing loops, Cisco router configuration does not allow BGP routes to be redistributed into an IGP.

D. Because BGP routes are not advertised unless they are known by the IGP, Cisco automatically redistributes routes into BGP.

Question 7# - The ABC.com network administrator has configured route filters on a router. What are three reasons to control routing updates via route filtering? (Select three)

A. For easier implementation
B. For simple security
C. To control network overhead on the wire
D. To hide certain networks from the rest of the organization
E. To prevent adjacencies from forming

Question 8# - Router ZXBP47 is configured as a route reflector. What would happen if router ZXBP47 would receive an update from a peer in a different autonomous system?

A. It discards the update.
B. It sends the update to all IBGP peers.
C. It sends the update only to non clients.
D. It sends the update only to route reflector clients.
E. It sends the update to all routers in the autonomous system.
