 According to the syllabus, dynamic analysis tools are tools that perform testing or analysis by executing the software or a part of it. Dynamic analysis tools can help detect defects or problems that only appear during runtime, such as memory leaks, performance issues, concurrency errors, etc. The answer A is correct because it suggests using a dynamic analysis tool for detecting a memory leak during performance testing. A memory leak is a situation where a code component fails to release memory after it has finished using it, causing memory exhaustion and degradation of performance. A dynamic analysis tool can monitor the memory usage of the code component and identify any memory leaks. The other answers are incorrect because they suggest using tools that are not suitable for detecting memory leaks during performance testing. A test execution tool is a tool that executes test cases automatically or semi-automatically. A configuration management tool is a tool that controls and tracks changes to the software components and documentation. A coverage measurement tool is a tool that measures how much of the code or functionality has been exercised by a test suite.

Regression testing is a type of testing that is performed after a software system has been changed or modified to verify that the changes have not introduced any new defects or adversely affected the existing functionality of the system. Regression testing can be performed when the software system undergoes different types of changes, such as:

• Corrective changes: Changes that fix defects or errors in the software system
• Adaptive changes: Changes that adapt the software system to new platforms or environments
• Perfective changes: Changes that improve the performance or usability of the software system
• Preventive changes: Changes that avoid potential problems or issues in the software system

In this case, the software system was re-deployed because the backend database was changed from one vendor to another, which is an example of an adaptive change. Therefore, the test manager decided to perform some functional tests on the re-deployed system to ensure that the change did not affect the functionality of the system. This is an example of regression testing.

The other types of testing mentioned in the question are not relevant for this scenario. For example:

• Non-functional testing: This type of testing verifies the non-functional aspects of the software system, such as reliability, performance, security, usability, etc.
• Structural testing: This type of testing verifies the internal structure or implementation of the software system, such as code, architecture, design, etc.
• Unit testing: This type of testing verifies individual components or units of software in isolation from other components or systems.

Percentage of work done in test environment preparation is a metric that measures how much of the required test environment setup has been completed. This metric is useful for monitoring the test progress because it indicates whether the test environment is ready for executing the planned test cases or not.
