QUESTION 1
Exhibit:

A network administrator is troubleshooting an EIGRP connection between RouterA, IP address
10.1.2.1, and RouterB, IP address 10.1.2.2. Given the debug output on RouterA, which two
statements are true? (Choose two.)

A. RouterA received a hello packet with mismatched autonomous system numbers.
B. RouterA received a hello packet with mismatched hello timers.
C. RouterA received a hello packet with mismatched authentication parameters.
D. RouterA received a hello packet with mismatched metric-calculation mechanisms.
E. RouterA will form an adjacency with RouterB.
F. RouterA will not form an adjacency with RouterB.

Answer: D,F

Explanation:


QUESTION 2
When troubleshooting an EIGRP connectivity problem, you notice that two connected EIGRP
routers are not becoming EIGRP neighbors. A ping between the two routers was successful. What
is the next thing that should be checked?

A. Verify that the EIGRP hello and hold timers match exactly.
B. Verify that EIGRP broadcast packets are not being dropped between the two routers with the
show ip EIGRP peer command.
C. Verify that EIGRP broadcast packets are not being dropped between the two routers with the
show ip EIGRP traffic command.
D. Verify that EIGRP is enabled for the appropriate networks on the local and neighboring router.

Answer: D

Explanation:


QUESTION 3
Refer to the exhibit.

How would you confirm on R1 that load balancing is actually occurring on the default-network
(0.0.0.0)?

A. Use ping and the show ip route command to confirm the timers for each default network resets
to 0.
B. Load balancing does not occur over default networks; the second route will only be used for
failover.
C. Use an extended ping along with repeated show ip route commands to confirm the gateway of
last resort address toggles back and forth.
D. Use the traceroute command to an address that is not explicitly in the routing table.

Answer: D

QUESTION 4
Which IPsec mode will encrypt a GRE tunnel to provide multiprotocol support and reduced
overhead?

A. 3DES
B. multipoint GRE
C. tunnel
D. transport

Answer: D

Explanation:


QUESTION 5
Which three features are benefits of using GRE tunnels in conjunction with IPsec for building siteto-
site VPNs? (Choose three.)

A. allows dynamic routing over the tunnel
B. supports multi-protocol (non-IP) traffic over the tunnel
C. reduces IPsec headers overhead since tunnel mode is used
D. simplifies the ACL used in the crypto map
E. uses Virtual Tunnel Interface (VTI) to simplify the IPsec VPN configuration

Answer: A,B,D
