Question

A network technician incorrectly wired switch connections in your organization's network. It effectively disabled the switch as though it was a victim of denial of service attack. What should have be done to prevent this in the future?A. Install an IDS. B. Only use Layer 2 switches. C. Install SNMP on the switches. D. Implement STP or RSTP.

Answer 1

Answer:

The answer is D. Implement STP or RSTP.

Explanation:

STP (Spanning Tree Protocol) was built to serve as a remedy for network issues. Existing before switches were developed, it works as a substitute for a switch when a switch is wired incorrectly (as seen in the question) or when it fails. STP has two roles:

1. To serve as an alternative when there is network failure or changes.
2. To block out issues caused by loops on a network

RSTP (Rapid Spanning Tree Protocol) was built to optimize the standard STP. When there is a topology change, spanning tree convergence is much faster than the standard STP.

To prevent network failure in the future, STP or RSTP should be implemented.
