Your team is tasked with diagnosing intermittent network traffic issues on a high-speed corporate network. You decide to use a network tap to monitor traffic between two critical switches. When installing the tap, what is crucial to ensure effective monitoring and minimal impact on network performance?
Implement an additional hub between the switches
Use an active tap
Use a passive tap
Deploy an extra switch dedicated to monitoring the traffic
Using a passive tap is crucial when installing a network tap in a situation where you do not want to affect network performance or integrity. Passive taps do not require power and do not actively interact with the network, hence they do not introduce points of failure or latency. Active taps require power and can potentially introduce latency or points of failure if there are power issues, while network switches and hubs are not advisable for monitoring as they can modify or reroute the traffic, which defeats the purpose of an unbiased monitoring setup.
