A+||BRAND NEW!!
Most Tested Areas: Performance Testing
Principles, Workload Modeling, Test Design,
Monitoring, Analysis, Performance Risks,
Tools, CI/CD Integration, Cloud & Distributed
Testing, Results Interpretation
1. What is the primary objective of performance testing?
To find functional defects
To evaluate system responsiveness and stability under load
To verify code style compliance
To test user interface design
Performance testing focuses on speed, scalability, and
stability under expected workloads.
2. Which workload model represents real user behavior most
accurately?
Uniform distribution
Random spikes only
Operational profile based on production usage
Single-user execution
, Operational profiles mirror actual production patterns,
giving realistic results.
3. Response time is best defined as:
Server processing time only
Network latency only
Total time from request sent to response received
Time to render UI after login
It includes network, server, and client processing delays.
4. Throughput measures:
Number of errors per second
CPU cycles consumed
Amount of work processed per unit time
Number of test cases executed
Typically measured in transactions per second.
5. A system that handles increasing load by adding resources
demonstrates:
Latency
Reliability
Scalability
Portability
Scalability reflects growth capability without performance
loss.
6. Stress testing aims to:
Validate normal operation
Measure peak business load only
Determine system breaking point and recovery
, Verify usability
It pushes beyond limits to observe failure behavior.
7. Soak testing primarily detects:
Security vulnerabilities
Functional regressions
Memory leaks and resource depletion over time
UI inconsistencies
Long-duration tests reveal gradual degradation.
8. Which metric indicates system stability over long runs?
Peak TPS
Minimum response time
Error rate trend over time
Build duration
A rising error trend signals instability.
9. Bottlenecks are identified by:
Lowest CPU usage
Highest code coverage
Resource saturation limiting throughput
Number of passed tests
Performance stops improving when a resource maxes out.
10. Virtual users simulate:
Only database connections
Only browser rendering
Concurrent real user activity
Network hardware behavior
They emulate simultaneous system interactions.
