- D.
Add alternate physical paths for data to traverse the networks
Correct Answer
D. Add alternate pHysical paths for data to traverse the networksExplanation
When planning for redundancy on a hierarchical network design, it is important to add alternate physical paths for data to traverse the networks. This means creating multiple physical connections between devices to ensure that if one path fails, data can still flow through an alternate path. This improves network reliability and minimizes downtime in case of a failure.Rate this question:

Which design feature will limit the size of a failure domain in an enterprise network?
- A.
The use of a collapsed core design
- B.
The use of the building switch block approach
- C.

- D.
The purchase of enterprise equipment that is designed for large traffic volume
Correct Answer
B. The use of the building switch block approachExplanation
The use of the building switch block approach will limit the size of a failure domain in an enterprise network. This approach involves dividing the network into smaller blocks or segments, with each block having its own switch. By doing so, any network failure or issue will be confined to that specific block and will not affect the entire network. This helps in isolating and containing failures, minimizing their impact and making troubleshooting and maintenance easier.Rate this question:

- C.
S4 and PC_2
- D.
S1 and S4
Correct Answer
A. PC_3 and AP_2Explanation
When switch S3 loses power, the devices that exist in the same failure domain are PC_3 and AP_2. This means that if switch S3 fails, these devices will also be affected and lose connectivity. The other options, S4 and PC_2 or S1 and S4, do not fall within the same failure domain as switch S3.Rate this question:

A network administrator is planning redundant devices and cabling in a switched network to support high availability. Which benefit will implementing the Spanning Tree Protocol provide to this design?
- A.
Multiple physical interfaces can be combined into a single EtherChannel interface.
- B.
Redundant paths can be available without causing logical Layer 2 loops.
- C.
Network access can be expanded to support both wired and wireless devices.

Correct Answer
B. Redundant paths can be available without causing logical Layer 2 loops.Explanation
Implementing the Spanning Tree Protocol (STP) in a switched network design will provide the benefit of having redundant paths available without causing logical Layer 2 loops. STP prevents network loops by blocking redundant paths and only allowing one active path at a time. This ensures that there are backup paths available in case of link failures, while also maintaining a loop-free topology to prevent broadcast storms and other issues that can occur with loops.Rate this question:
