A performance risk is identified that could cause the system to fail a contractual service-level agreement (SLA) for response time. How can this risk affect project success?

It guarantees the project will be cancelled

It will have no impact because SLAs are not part of project success

It may result in financial penalties and damage to the organization's reputation

It only affects the testing team, not the overall project

A performance risk is identified that could cause the system to become unresponsive under peak load. How can this risk most directly affect project outcomes?

It has no effect on project timelines or user satisfaction

It will automatically increase the project's development budget

It guarantees the project will miss its release deadline

It may lead to user dissatisfaction and potential loss of customers

A company is about to release a new version of its customer portal. The performance test team has identified a risk that the login page may be slow under peak load. The project manager asks what the impact could be on user satisfaction. Which impact is most likely?

There will be no impact because users expect some delay during peak times.

Users will not notice the slowness because login is a simple operation.

Users may become frustrated and switch to a competitor's service, leading to customer churn.

The only impact is on the technical support team, who will receive more tickets.

A performance risk is identified: a new feature may cause the database to become a bottleneck under normal usage. Which mitigation strategy is most appropriate to prevent or reduce this risk?

Perform database tuning and optimize queries

Reduce the number of test cases

Increase the frequency of code reviews
