QUESTION 33:
Which of the following statements are true about EIGRP operation? (Choose three)
A. When summarization is configured, the router will add a route to null 0
B. The summary route remains in the route table, even if there are no more specific
routes to the network.
C. Summarization is configured on a per-interface level.
D. The maximum metric for the specific routes is used as the metric for the summary
route.
E. Automatic summarization across major network boundaries is enabled by default.
Answer: A, C, E
Explanation:
Using the ip summary-address eigrp summarization command will causes the creation of
an EIGRP summary default route to the null0 interface with an administrative distance of
5. Caution should be taken when using this as a default route. The low administrative
distance of this default route can cause this route to displace default routes learned from
other neighbors from the routing table. If the default route learned from the neighbors is
displaced by the summary default route, or if the summary route is the only default route
present, all traffic destined for the default route will not leave the router, instead, this
traffic will be sent to the null0 interface where it is dropped.
By default, Cisco routers will automatically summarize EIGRP routes across major
network boundaries. With EIGRP, You can configure a summary aggregate address for a
specified interface. If there are any more specific routes in the routing table, EIGRP will
advertise the summary address out the interface with a metric equal to the minimum of all
more specific routes.
Incorrect Answers:
B: When all of the specific routes used within a summary route are deleted from the
routing table, the summary route will also be deleted.
D: The metric used in a summary route is the best metric from among the summarized
routes, not the maximum (worst).
QUESTION 34:
What action does an EIGRP router take when it cannot find a feasible successor for
a network?
A. It examines the routing and neighbor tables for the next best path.
B. It transitions from passive to active state for that network and queries its neighbors.
C. It examines the topology for a next best path.
D. It transitions from active to passive state for the next network and queries its
neighbors.
Answer: B
Explanation:
With EIGRP, A topology table entry for a destination can have one of two states. A route
is considered in the Passive state when a router is not performing a route recomputation.
The route is in Active state when a router is undergoing a route recomputation. If there
are always feasible successors, a route never has to go into Active state and avoids a
route recomputation.
When there are no feasible successors, a route goes into Active state and a route
recomputation occurs. A route recomputation commences with a router sending a query
packet to all neighbors. Neighboring routers can either reply if they have feasible
successors for the destination or optionally return a query indicating that they are
performing a route recomputation. While in Active state, a router cannot change the
next-hop neighbor it is using to forward packets. Once all replies are received for a given
query, the destination can transition to Passive state and a new successor can be selected.
QUESTION 35:
The Certkiller EIGRP network is displayed in the following topology diagram:
You work as a network technician at Certkiller .com. Study the exhibits carefully. If
the command “variance 3″ was added to the EIGRP configuration of Certkiller 5,
which path or paths would be chosen to route traffic from Certkiller 5 to network X?
A. Certkiller 5- Certkiller 2- Certkiller 1
B. Certkiller 5- Certkiller 2- Certkiller 1 and Certkiller 5- Certkiller 3- Certkiller 1.
C. Certkiller 5- Certkiller 3- Certkiller 1 and Certkiller 5- Certkiller 4- Certkiller 1.
D. Certkiller 5- Certkiller 2- Certkiller 1, Certkiller 5- Certkiller 3- Certkiller 1, and
Certkiller 5- Certkiller 4- Certkiller 1.
