Answer 1

show vtp counters

Question 2

Which IOS command is used to view information about OSFP routing process

Answer 2

show ip ospf

Question 3

Your network consists of one HSRP group with six routers. All the routers are functioning correct, and the network has been stable of many days now. In which HSRP will the majority of Routers be in?

Answer 3

Listen

Question 4

What are the output columns of the command ‘show ip ospf neighbour’ ?

Answer 4

1. Neighbour ID - of the neighbour
2. Pri - Priority of the neighbour
3. State - Current OSPF state of the neighbour
4. Dead Time - Current count down since last hello from the neighbour
5. Address - IP address of the neighbour
6. Interface - The neighbour was learned about via.

Question 5

Which Network types will OSPF elect a DR?

Answer 5

Frame Relay
NBMA - Non-Broadcast Multi-Access

Ethernet segment
Broadcast Multi Access

Question 6

What command was used to generate the following output?

P 172.16.16.0/24, 1 successors, FD is 284244
via 172.16.250.2 (284244/17669856), Serial0/0
via 172.16.251.2 (12738176/27819002), Serial0/1
P 172.16.250.0/24 , 1 successors, FD is 2248564
via Connected, Serial0/0
P 172.16.10.0/24 1 Successors, FD is 284244
via 172.16.50.1 (284244/17669856), Serial1/0

Answer 6

show ip eigrp topology

Question 7

What is the AD value of a EIGRP Summery route ?

Answer 7

5 for a Smmary route

90 is for learned EIGRP routes.

Question 8

What is a requirement for both ipv4 and ipv6 EIGRP

Answer 8

a router ID
For IPv6, if there are not IPv4 interfaces, a router ID needs to be defined.
For IPv4, a router ID can be defined or selected from a configured IPv4 address.

Question 9

When defining a Network in EIGRP, which of the following are valid commands

network 192.168.1.1
network 10.0.0.0
network 10.2.2.2
network 192.168.1.0

Answer 9

network 10.0.0.0
network 192.168.1.0

The command should be in terms of the netowrk or subnet of the network in which the interface resides. And not the ip on the interface.

Question 10

What are EIGRP Packets?

Answer 10

Hello/Ack
Update
Query
Reply
Requests

Question 11

What Algorithem is used in EIGRP for selection of the best route?

Answer 11

DUAL - Diffusing Update ALgorithm

Question 12

What command will show you a record of all paths to all destination networks in the EIGRP AS?

Answer 12

show ip eigrp topology

This will include routes that have not been installed in the routing table.

Question 13

How is the designated router determined by OSPF on a multi-access network segement?

Answer 13

The highest interface priority, and then the highest RID (Router ID)

Question 14

Which is not a possible component of EIGRP composite metric?

Bandwidth
Cost
Delay
Load

Answer 14

Cost - Is the metric for OSPF

EIGRP can use;
bandwidth (default)
delay (default)
load
reliability
MTU

Question 15

What can cause a OSPF neighbor adjacency from forming ?

Answer 15

Mismatched OSPF Area Number
Mismatched OSPF Area Type
Mismatched subnet and subnet mask
Mismatched OSPF HELLO and dead timer values

Question 16

What are the Default K values and what are they used for ?

Answer 16

1 0 1 0 0
K values are used for EIGRP, to create the Composit Metric.

K1 = Bandwidth
K2 = Load
K3 = Delay
K4 = Reliability
K5 = MTU

Question 17

True or False

EIGRP uses a 32-bit Metric

Answer 17

True
