Which of the following techniques is used to trace system calls as the software is executing?
-
Source code analysis
-
Performance Testing
-
Black Box debugging
-
Dynamic Code Analysis
Dynamic Code Analysis involves analyzing software WHILE it executes, which includes tracing system calls to observe runtime behavior. Source code analysis (A) is static analysis without execution. Performance Testing (B) measures speed and resource usage, not system call tracing. Black Box debugging (C) examines external behavior without internal visibility.
To answer this question, you need to understand the different techniques used for tracing system calls during software execution. Let's go through each option to understand why it is correct or incorrect:
Option A) Source code analysis - This option is incorrect because source code analysis involves reviewing the source code of a program to identify potential issues or bugs. It does not involve tracing system calls during software execution.
Option B) Performance testing - This option is incorrect because performance testing focuses on evaluating the speed, responsiveness, and stability of a software system under varying workloads. It does not involve tracing system calls during software execution.
Option C) Black Box debugging - This option is incorrect because black box debugging refers to the process of debugging a software system without access to its internal workings. It does not specifically involve tracing system calls during software execution.
Option D) Dynamic Code Analysis - This option is correct because dynamic code analysis is a technique used to trace system calls as the software is executing. It involves analyzing the behavior of a program at runtime to identify system calls and understand how they are being used.
The correct answer is D) Dynamic Code Analysis. This option is correct because it specifically involves tracing system calls during software execution.
