Refer to the exhibit. A customer reports poor application performance on their OLTP database, which is on an existing two-node HP P4500 Virtualization provides you with the chart in the exhibit…

If the maximum acceptable response time is *reached* during business hours, it implies the system is performing at the very edge of its tolerance or exceeding it, which constitutes poor performance, but it's a specific cause rather than the overarching state of not reaching optimal performance.

If the maximum acceptable response time is *reached* during backup, it indicates performance issues during that specific period, but doesn't encompass the general 'poor application performance' statement for the entire measured period.

If a customer reports 'poor application performance,' it inherently means the system is not performing at its desired or optimal level. Therefore, concluding that optimal response time is not reached during the entire measurement period directly supports and explains the observation of poor application performance.

Stating that optimal response time is *reached* during business hours directly contradicts the initial problem statement that the customer reports 'poor application performance.'
