A test analyst is profiling a Java application and notices that a particular method is called frequently and consumes a significant amount of CPU time. The method performs a database query in a loop. What is the most likely performance issue?

The method is not using a prepared statement.

The method is using too much memory.

The method is executing a database query in a loop, causing repeated round-trips.

The method is not using an index on the database table.

What is the primary purpose of performance efficiency analysis in the context of static and dynamic testing?

To confirm that the system is easy to maintain and modify

To verify that the system meets functional requirements

To identify and evaluate how well the system uses resources and responds under specified conditions

To ensure that the system is free from security vulnerabilities

What does the 'resource utilization' metric indicate in performance efficiency analysis?

The total number of users that can access the system simultaneously

The number of transactions processed per second

The percentage of time a system component is busy processing work

The time taken for a system to respond to a user request

When analyzing performance test results, what does a 'bottleneck' refer to?

A test case that fails due to a functional defect

A metric that measures the number of users

A component that limits the overall performance of the system

Analysis of Performance Efficiency CTAL-TTA Practice Questions (Page 3)

Part of the Domain 3: Static and Dynamic Analysis domain, which makes up ~21% of our current practice bank. ISTQB does not publish an official question count, but from its 120-minute exam (~50–80 total, ~11–17 in this domain), expect 1–2 from this objective — we provide 24 practice questions to prepare you well beyond it.
