Question 14

Why is it crucial to establish specific network performance metrics for effective monitoring and troubleshooting?

Accepted Answer

Performance metrics serve as benchmarks for detecting deviations from normal network behavior, facilitating timely issue identification.

Answer

Defining network performance metrics is a time-consuming process that often hinders troubleshooting efforts.

Answer

Performance metrics can be arbitrarily chosen without affecting the effectiveness of troubleshooting.

Answer

Troubleshooting can be performed effectively even without defined performance metrics.
