A mid-sized company needs to performance test a web application that uses a modern JavaScript framework. The team has some experience with scripting but no dedicated performance engineers. They want to integrate tests into their Azure DevOps pipeline and have a moderate budget. Which tool selection is most appropriate?

A cloud-based load testing service with no CI integration

An open-source tool with scripting and a community plugin for Azure DevOps

A simple load generator that only sends HTTP requests

A commercial tool with a GUI and Azure DevOps integration

A performance test of a REST API shows that the 95th percentile response time is 2 seconds, but the average is 300 ms. The test ran with 100 concurrent users. The application logs show occasional slow queries to a legacy database. What is the most appropriate interpretation and next step?

Increase the number of concurrent users to see if the problem worsens

The API is performing well overall; no action is needed

The slow queries are causing outliers; investigate and optimize the database queries

Switch to a different load testing tool to get more accurate results

A company is experiencing intermittent slowdowns in their customer portal during peak hours. They suspect a bottleneck but are unsure where. What is the primary benefit of using a performance testing tool in this situation?

It can automatically fix the performance issue

It can replace the need for monitoring in production

It can simulate peak load to reproduce the issue and identify the bottleneck

It can guarantee that the application will not have performance issues

A company uses GitLab CI for their build pipeline. They want to trigger a performance test after a successful deployment to a staging environment. The performance test tool has a CLI that can be run in a Docker container. What is the best way to integrate this?

Manually run the performance test after each deployment

Create a cron job on the staging server to run the test daily

Add a job in the GitLab CI pipeline that runs the performance test CLI in a Docker container after the deployment job

Use a separate CI tool just for performance testing

A large enterprise with a complex microservices architecture needs to run performance tests that simulate realistic user behavior across multiple services. They have a dedicated performance engineering team and a substantial budget. Which type of tool is most appropriate?

An open-source tool that requires scripting and manual integration

A commercial enterprise tool with advanced analytics and support

A cloud-based service with pay-per-use pricing

A simple load generator that only sends HTTP requests
