SG0-001 · Question #58

An application database is operating slowly and no faults have been detected on the storage or host. Which of the following will determine if the storage device is performing outside of its normal ope

The correct answer is A. Current performance versus recorded baseline. To determine if slow application performance is due to the storage device, its current performance metrics must be compared against a historical baseline.

Question

An application database is operating slowly and no faults have been detected on the storage or host. Which of the following will determine if the storage device is performing outside of its normal operating expectations?

Options

  • CForecast and capacity planning trend
  • DThorough review of the switch and storage event logs

Why each option

To determine if slow application performance is due to the storage device, its current performance metrics must be compared against a historical baseline.

ACurrent performance versus recorded baselineCorrect

Comparing current storage performance metrics against a recorded baseline established during normal operations identifies deviations that indicate the device is not performing as expected. A baseline provides a reference point for normal behavior, allowing identification of performance degradation even without explicit faults.

BThorough review of the audit logs of the device

Audit logs track security-related events or user actions, not performance metrics, making them unhelpful for diagnosing slow performance without faults.

CForecast and capacity planning trend

Forecast and capacity planning trends are used for future resource allocation, not for immediate diagnosis of current performance issues.

DThorough review of the switch and storage event logs

Event logs show faults, errors, or significant events; however, since 'no faults have been detected,' reviewing them further won't identify a subtle performance degradation without a baseline for comparison.
