Cisco Implementing cisco ip routing Sample Questions:

1. During a recent OSPF election among three routers, RTA was elected the DR and RTB was elected the BDR, as seen in the graphic. Assume that RTA fails, and that RTB takes the place of the DR while RTC becomes the new BDR. What will happen when RTA comes back online?

A) A new election will take place establishing an all new DR and BDR based on configured priority levels and MAC addresses.
B) RTA will take the place of DR only if RTB fails.
C) RTA will take the place of DR only if both RTB and RTC fail.
D) RTA will take the place of DR immediately upon establishing its adjacencies.

2. Refer to the exhibit.

You are the network administrator responsible for the NProuter, the 10.1.1.1 router, and the
10.1.1.2 router. What can you determine about the OSPF operations from the debug output?

A) The NProuter serial0/0 interface has been configured with an OSPF network type of "pointtopoint".
B) The NProuter has two OSPF neighbors in the "Full" adjacency state.
C) The 10.1.1.1 and 10.1.1.2 routers are not using the default OSPF dead and hello timers setting.
D) The NProuter serial0/0 interface has the OSPF dead timer set to 10 seconds.
E) The "Mismatched" error is caused by the expiration of the OSPF timers.

3. Refer to the exhibits. What can be done to fix the problem?
RouterA#debug ip ospf events
OSPF events debugging is on
RouterA#
04:43:16: OSPF. Rcv pkt from 10.3.0.2, Ethernet0/1, area 0.0.0.1 mismatch area 0.0.0.2 in the header
04:43:19: OSPF. Rcv hello from 10.100.100.3 area 0 from Ethernet0/0 10.1.0.1
04:43:19: OSPF. End of hello processing

A) Configure the E0/1 interfaces of router A and router B to be in area 0.
B) Shut down the E0/1 interfaces in router A and router B as OSPF does not allow "back doors" between areas.
C) Change router A interface E0/1 to area 0.0.0.2.
D) Change router B E0/1 interface to area 0.
E) Remove the E0/1 interfaces in router A and router B from the OSPF process. Use static routes to route data directly from router A to router B to avoid passing data through router C in area 0.

4. Which two types of routes will be advertised with the EIGRP configuration as shown?
(Choose two.)
router eigrp 100
network 10.0.0.0
eigrp stub

A) stub
B) receive-only
C) dynamic
D) connected
E) summary
F) static

5. Refer to the exhibit.

A Boston company bought the assets of a New York company and is trying to route traffic between the two data networks using EIGRP over EoMPLS. As a network consultant, you were asked to verify the interoperability of the two networks.
From the show ip route command output, what can you tell the customer about the traffic flow between the subnet in New York (172.16.8.0/24) and the subnets in Boston (172.16.16.0/24 and 10.10.16.0/24)?

A) Traffic will flow between the 172.16.8.0 subnet and 172.16.16.0 without any further configuration changes. However, auto-summary must be disabled on N1 and B1 before traffic can flow between the 172.16.8.0 subnet and the 10.10.16.0 subnet.
B) Traffic is flowing between the 172.16.8.0 subnet and subnets 172.16.16.0 and 10.10.16.0 and no configuration changes are needed.
C) Auto-summary must be disabled on N1 and B1 before traffic can flow between the 172.16.8.0 subnet and the 172.16.16.0 subnet. However, traffic will flow between the 172.16.8.0 subnet and
10.10.16.0 without any further configuration changes.
D) Auto-summary must be disabled on N1 and B1 before traffic can flow between the 172.16.8.0 subnet and subnets 172.16.16.0 and 10.10.16.0.
