Comparing Network Performance for Anomalies

Which of the following should current network performance be compared against to determine network anomalies?

A.

Baseline

B.

Traffic analysis

C.

Packet capture

D.

Logs.

A.

The correct answer is A. Baseline.

Network performance is the measure of the quality of service (QoS) provided by a network. It is essential to establish a baseline performance of the network, which is a snapshot of the normal or expected network behavior. This baseline can then be used as a reference point to compare current network performance against to identify any anomalies.

By measuring the network's performance against the baseline, network administrators can identify any deviations from the norm, which could indicate problems with network infrastructure, software, or hardware. Such anomalies can be caused by various factors, including increased network traffic, bottlenecks, faulty equipment, security breaches, and configuration issues.

Traffic analysis, packet capture, and logs are other tools that can be used to troubleshoot network problems. Traffic analysis involves examining the flow of network traffic to identify any patterns or anomalies. Packet capture involves capturing and analyzing packets of data transmitted over the network. Logs record information about network events, such as errors, warnings, and system events, which can help troubleshoot problems.

In summary, while traffic analysis, packet capture, and logs can be helpful in identifying network problems, it is essential to have a baseline to compare against to determine network anomalies accurately.
