Accepted Answer

In the topology table

Question 11

Mr. Davis needs to configure EIGRP on a network with multiple paths to the same destination. How can he ensure that the paths with lower delay are preferred?

Accepted Answer

Adjust the K-values

Question 12

Ms. Clark is troubleshooting an EIGRP network and notices suboptimal routing. She suspects a misconfigured EIGRP metric. What should she verify to diagnose the issue?

Accepted Answer

Bandwidth and delay settings on interfaces

Question 13

Which type of OSPF router connects an OSPF area to the backbone area (Area 0)?

Accepted Answer

Area Border Router (ABR)

Question 14

What is the function of OSPF Hello packets?

Accepted Answer

To establish and maintain neighbor relationships

Question 15

Which OSPF area type is designed to prevent the flooding of external LSAs?

Accepted Answer

Stub area

Question 16

Mr. Green is configuring OSPF in a multi-area network and needs to ensure that one of the areas does not receive external LSAs. What type of area should he configure?

Accepted Answer

Stub area

Question 17

What is the primary advantage of placing the Layer 3 boundary at the access layer in a campus network?

Accepted Answer

Reduces the size of the broadcast domain

Question 18

Which of the following is a key design consideration for Layer 2 in an enterprise campus network?

Accepted Answer

Spanning Tree Protocol configuration

Question 19

Mr. Johnson needs to design a campus network where rapid convergence and minimal downtime are crucial. Which Spanning Tree Protocol variant should he use?

Accepted Answer

RSTP

Question 20

Ms. Smith is designing an enterprise network and wants to ensure optimal VLAN management. Which feature should she prioritize in her Layer 2 design?

Accepted Answer

VLAN Trunking

Question 21

What is the main benefit of using OSPF in an enterprise network?

Accepted Answer

Fast convergence and scalability

Question 22

Which type of OSPF area reduces the size of routing tables by blocking external routes?

Accepted Answer

Totally stubby area

Mr. Brown is configuring OSPF in a network that requires multiple autonomous systems. Which OSPF feature should he use to manage inter-area routing?

Accepted Answer

Area Border Routers (ABRs)

Question 24

Ms. Green needs to design an OSPF network that minimizes the impact of topology changes in one area on other areas. Which OSPF area type should she use?

Accepted Answer

Stub area

Question 25

What is a key difference between OSPF and IS-IS in terms of network design?

Accepted Answer

IS-IS runs directly over the data link layer, while OSPF runs over IP

Question 26

Which IS-IS network type has routers that only belong to a single area?

Accepted Answer

Level-1

Question 27

Mr. White is designing an IS-IS network for an enterprise with multiple geographic locations. Which type of IS-IS routers should he use to interconnect these areas?

Accepted Answer

Level-2 routers
