Multiple choice

A network administrator added two switches and a new VLAN over the past weekend. How can the administrator determine if the additions and changes improved performance and availability on the company intranet?

  1. Perform a baseline test and compare the current values to values that were obtained in previous weeks.

  2. Interview departmental secretaries and determine if they think load time for web pages is improved.

  3. Compare the hit counts on the company web server for the current week to the values that were recorded from previous weeks.

  4. Performance on the intranet can be determined by monitoring load times of company web pages from remote sites.

A Correct answer
Explanation

A baseline test provides quantitative measurements of network performance metrics (throughput, latency, error rates, utilization) under normal conditions. By comparing current values to the baseline, the administrator can objectively determine if the new switches and VLAN improved performance and availability. Subjective measures like user interviews are unreliable, and web server hit rates don't measure intranet performance. Monitoring from remote sites would test WAN/internet performance, not internal intranet.
