EIGRP-ChatGPT2

Question 1

In EIGRP, what is the purpose of the “Hello” packets?

A) To advertise network routes to neighbors
B) To request routing updates from neighbors
C) To establish and maintain neighbor adjacencies
D) To identify routers in different autonomous systems

Answer 1

C) To establish and maintain neighbor adjacencies

Explanation:
EIGRP uses “Hello” packets to discover and establish neighbor adjacencies with other routers in the same autonomous system (AS). These packets are vital for forming and maintaining neighbor relationships.

Question 2

What is the primary advantage of EIGRP’s Dual (Diffusing Update Algorithm) over traditional distance-vector algorithms?

A) Faster convergence
B) Simplicity of configuration
C) Greater scalability
D) Support for multiple routing protocols

Answer 2

A) Faster convergence

Explanation:
One of the primary advantages of EIGRP’s Dual algorithm is faster convergence. It allows EIGRP to quickly adapt to changes in the network topology, reducing the time it takes to converge to a stable routing state.

Question 3

Which EIGRP packet type is used to exchange routing information, including updates about network topology changes?

A) Hello
B) Acknowledgment
C) Update
D) Query

Answer 3

C) Update

Explanation:
EIGRP uses “Update” packets to exchange routing information, including updates about changes in network topology. These packets are crucial for sharing routing information between EIGRP routers.

Question 4

What is the significance of the “K-values” in EIGRP?

A) They represent the number of hops to reach a destination.
B) They are used to calculate the composite metric.
C) They specify the administrative distance of EIGRP routes.
D) They define the EIGRP neighbor hold-down timer.

Answer 4

B) They are used to calculate the composite metric.

Explanation:
The “K-values” (also known as “metrics weights”) in EIGRP are used to calculate the composite metric, which determines the best path to a destination. By adjusting these values, network administrators can influence route selection based on various factors like bandwidth, delay, reliability, and load.

Question 5

What is the purpose of the EIGRP “Topology Table”?

A) To store the best path to reach a destination network.
B) To store all known network routes in the autonomous system.
C) To store feasible successors for load balancing.
D) To maintain a list of EIGRP neighbor routers.

Answer 5

C) To store feasible successors for load balancing.

Explanation:
The EIGRP “Topology Table” is used to store feasible successors, which are alternative routes to a destination network that meet the EIGRP feasibility condition. These routes can be used for load balancing and redundancy in the network.
