How does EIGRP notice when a neighboring router fails?
- A.
The failing neighbor sends a message before failing.
- B.
The failing neighbor sends a “dying gasp” message.
- C.
The router notices a lack of routing updates for a period of time.
- D.
The router notices a lack of Hello messages for a period of time.
Correct Answer
D. The router notices a lack of Hello messages for a period of time. -
- 3.
Which of the following is true about the concept of EIGRP feasible distance?
- A.
A route’s feasible distance is the calculated metric of a feasible successor route.
- B.
A route’s feasible distance is the calculated metric of the successor route.
- C.
The feasible distance is the metric of a route from a neighboring router’s perspective.
- D.
The feasible distance is the EIGRP metric associated with each possible route to reach a subnet.
Correct Answer
B. A route’s feasible distance is the calculated metric of the successor route.Explanation
The Feasible Distance (FD) is, for all known routes to reach a subnet, the metric for the best of those routes. The best route is called the successor route, and it is added to the IP routing table.Rate this question:

Which of the following is true about the concept of EIGRP reported distance?
- A.
A route’s reported distance is the calculated metric of a feasible successor route.
- B.
A route’s reported distance is the calculated metric of the successor route.
- C.
A route’s reported distance is the metric of a route from a neighboring router’s perspective.
- D.
The reported distance is the EIGRP metric associated with each possible route to reach a subnet.
Correct Answer
C. A route’s reported distance is the metric of a route from a neighboring router’s perspective.Explanation
A route’s reported distance (RD) is the metric used by the neighbor that advertised the route. A router uses it to determine which routes meet the feasibility condition for
whether the route can be a feasible successor route.Rate this question:

Which of the following network commands, following the command router eigrp 1, tells this router to start using EIGRP on interfaces whose IP addresses are 10.1.1.1, 10.1.100.1, and 10.1.120.1?
- A.
Network 10.0.0.0
- B.
Network 10.1.1x.0
- C.
Network 10.0.0.0 0.255.255.255
- D.
Network 10.0.0.0 255.255.255.0
Correct Answer(s)
A. Network 10.0.0.0
C. Network 10.0.0.0 0.255.255.255Explanation
The EIGRP network command supports a parameter of a classful network, enabling EIGRP on all interfaces in that classful network, or an address and wildcard mask. In the latter case, interface IP addresses that match the configured address, when applying ACL-like logic with the wildcard mask, match the command.Rate this question:

Routers R1 and R2 attach to the same VLAN with IP addresses 10.0.0.1 and 10.0.0.2, respectively. R1 is configured with the commands router eigrp 99 and network 10.0.0.0. Which of the following commands might be part of a working EIGRP configuration on R2 that ensures that the two routers become neighbors and exchange routes?
- A.
Network 10
- B.
Router eigrp 98
- C.
Network 10.0.0.2 0.0.0.0
- D.
Network 10.0.0.0
Correct Answer(s)
C. Network 10.0.0.2 0.0.0.0
D. Network 10.0.0.0Explanation
The EIGRP network 10.0.0.2 0.0.0.0 command exactly matches the interface with address 10.0.0.2 because of the wildcard mask, enabling EIGRP on that interface. The EIGRP ASN value must match on both routers. The network 10 command is
syntactically incorrect; the entire classful network must be configured.Rate this question:

Examine the following excerpt from a router’s CLI:Which of the following identifies a next-hop IP address on a feasible successor route?
- A.
10.1.6.3
- B.
10.1.4.2
- C.
10.1.5.4
- D.
It cannot be determined from this command output.
Correct Answer
C. 10.1.5.4Explanation
The first number in parentheses is the computed metric for a route, and the second number is the reported distance (RD) for the route. The route through 10.1.6.3 is the
successor route, so it is not a feasible successor route. For the other two routes, only the third route’s RD is less than or equal to the feasible distance (the metric of the
successor route).Rate this question:

Which of the following must occur to configure MD5 authentication for EIGRP?
- A.
Setting the MD5 authentication key via some interface subcommand
- B.
Configuring at least one key chain
- C.
Defining a valid lifetime for the key
- D.
Enabling EIGRP MD5 authentication on an interface
Correct Answer(s)
B. Configuring at least one key chain
D. Enabling EIGRP MD5 authentication on an interfaceExplanation
The MD5 key must be configured. It is not configured with an interface subcommand, but rather as part of a key chain. The useful lifetime of a key may be configured, but it is not required.Rate this question:
