A reported distance greater than 41024000.

A reported distance less than 3523840.*

A feasible distance greater than 41024000.

An administrative distance less than 170.

> If all router Ethernet interfaces in an EIGRP network are configured with the default EIGRP timers, how long will a router wait by default to receive an EIGRP packet from its neighbor before declaring the neighbor unreachable?.

10 seconds.

20 seconds.

15 seconds.*

30 seconds.

> Which EIGRP route would have the preferred administrative distance?.

An internal route.

An external route that is redistributed from RIP.

An external route that is redistributed from OSPF.

A summary route.*

> What is indicated when an EIGRP route is in the passive state?.

There is no activity on the route to that network.

The route has the highest path cost of all routes to that destination network.

The route is viable and can be used to forward traffic.*

The route is a feasible successor and will be used if the active route fails.

The route must be confirmed by neighboring routers before it is put in the active state.

> Why would a network administrator use a wildcard mask in the network command when configuring a router to use EIGRP?.

To send a manual summarization.

To exclude some interfaces from the EIGRP process.*

To subnet at the time of the configuration.

To lower the router overhead.

> Launch PT – Hide and Save PT.

Open the PT Activity. Perform the tasks in the activity instructions and then answer the question. Which code is displayed on the web server?.

Done.

EIGRP.

Complete.*

IPv6EIGRP.

> Fill in the blank.

In an EIGRP topology table, a route that is in a/an #” active ”# state will cause the Diffusing Update

Algorithm to send EIGRP queries that ask other routers for a path to this network.

> Where are EIGRP successor routes stored?.

Only in the routing table.

In the routing table and the neighbor table.

Only in the neighbor table.

In the routing table and the topology table.*

> Which three metric weights are set to zero by default when costs in EIGRP are being calculated?.(Choose three).

K1.

K2.*

K3.

K4.

K5.*

K6.

> How do EIGRP routers establish and maintain neighbor relationships?.

By exchanging hello packets with neighboring routers.*

By dynamically learning new routes from neighbors.

By exchanging routing tables with directly attached routers.

By comparing known routes to information received in updates.

By exchanging neighbor tables with directly attached routers .

> Refer to the exhibit. Which two networks contain feasible successors?. (Choose two).

192.168.51.0.

10.44.101.252.

10.44.104.253.

10.44.100.252.*

192.168.71.0.*

> Which destination MAC address is used when a multicast EIGRP packet is encapsulated into an

Ethernet frame?.

01-00-5E-00-00-0A.*

01-00-5E-00-00-0B.

01-00-5E-00-00-09.

01-00-5E-00-00-10

> Which statement describes a characteristic of the delivery of EIGRP update packets?.

EIGRP sends all update packets via unicast.

EIGRP sends all update packets via multicast.

EIGRP uses a reliable delivery protocol to send all update packets.*

EIGRP uses UDP to send all update packets.

> Refer to the exhibit. Which command should be used to configure EIGRP to only advertise the network that is attached to the gigabit Ethernet 0/1 interface?.

Network 172.16.23.64 0.0.0.63.*

Network 172.16.23.0 255.255.255.128.

Network 172.16.23.64 0.0.0.127.

Network 172.16.23.0 255.255.255.192.

> A new network administrator has been asked to verify the metrics that are used by EIGRP on a Cisco device. Which two EIGRP metrics are measured by using static values on a Cisco device?. (Choose two).

Load.

Bandwidth.*

MTU.

Delay.*

Reliability.

> Which command or commands must be entered on a serial interface of a Cisco router to restore the bandwidth to the default value of that specific router interface?.

Shutdown.

No shutdown.

Bandwidth 1500.

Copy running-config startup-config.

Reload.

No bandwidth.*

> Which table is used by EIGRP to store all routes that are learned from EIGRP neighbors?.

The neighbor table.

The topology table.*

The routing table.

The adjacency table.

> Which command is used to display the bandwidth of an interface on an EIGRP-enabled router?.

Show ip protocols.

Show ip interface brief.

Show interfaces.*

Show ip route.

> Place the options in the following order:

– not scored –.

*EIGRP for IPv4 only.*

*Both EIGRP for IPv4 and EIGRP for IPv6.*

*EIGRP for IPv6 only.*

> What is the purpose of using protocol-dependent modules in EIGRP?.

To accommodate routing of different network layer protocols.*

To identify different application layer protocols.

To describe different routing processes.

To use different transport protocols for different packets.

> When an EIGRP-enabled router uses a password to accept routes from other EIGRP-enabled routers, which mechanism is used?

Bounded updates.

Diffusing Update Algorithm.

EIGRP authentication.*

Partial updates.

Reliable Transport Protocol.

> Place the options in the following order:

*First.*
