What is the primary purpose of monitoring in dynamic performance analysis?

To observe the system's behavior and resource usage during execution

To review the source code for potential defects

To simulate user load on the system

To verify that the system meets functional requirements

What type of performance issue can static code analysis tools detect?

Potential infinite loops or inefficient algorithm complexity

Memory leaks that only occur under specific runtime conditions

Excessive resource consumption during peak load

Actual response time of a web service

During a static code review, a test analyst notices that a function that processes user input uses a regular expression that could cause catastrophic backtracking on certain inputs. What is the most appropriate action to address this performance risk?

Replace the regular expression with a simpler string operation.

Ignore the issue because it only affects malicious inputs.

Add more logging to the function.

Increase the timeout for the function.

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.
