Which of the following is a key factor in determining the suitability of a performance testing tool for a project?

The tool's ability to replace the need for manual testing

The team's familiarity with the tool

The tool's default color scheme

The tool's ability to work without any configuration

A performance test team needs to simulate 10,000 concurrent users for a web application that uses WebSocket for real-time updates. The tool they are evaluating supports HTTP/HTTPS but has limited WebSocket support. What should the team do FIRST?

Evaluate whether the tool's WebSocket support can handle the required concurrency and protocol specifics

Select a different tool that fully supports WebSocket without further evaluation

Proceed with the tool and simulate the load using HTTP requests only

Reduce the concurrency to 5,000 users to fit the tool's limitations

Which of the following is a recognized limitation of performance testing tools?

The ability to test all types of applications without any training

Scripting complexity for certain protocols or dynamic content

The ability to generate load without any hardware resources

The ability to produce results that are always accurate

A company is selecting a performance testing tool for a legacy application that uses a proprietary protocol. The team has experience with a specific commercial tool, but that tool does not support the proprietary protocol. What should the team do?

Use the commercial tool and test only the parts that use standard protocols

Ask the vendor to add support for the proprietary protocol

Select a different tool that supports the proprietary protocol, even if it requires training

Use the commercial tool and simulate the protocol with custom code

Which of the following is a common limitation of performance testing tools?

The ability to test any application without any configuration

The ability to run tests without any impact on the system under test

Scalability constraints that limit the number of virtual users a single instance can simulate

The ability to automatically fix performance issues found during testing
