Identifying Dead Code in Software Development
A software company has a shared codebase for multiple projects using the following strategy: • Unused features are deactivated but still present on the code. • New customer requirements trigger additional development work. Which of the following will most likely occur when the company uses this strategy?

Community Insight
The question tests the definition of 'dead code' versus other code types; the trap is confusing it with obfuscation or malicious intent.
This page explains that deactivated but present features constitute dead code, a common software security risk. It clarifies why this strategy leads to maintenance issues and potential vulnerabilities.
Learners often confuse 'dead code' with 'code obfuscation', thinking that hiding features makes them secure rather than just unused.

Expert Analysis
Why the Answer Is Correct
Dead code refers to source code that is included in the program but never executed during runtime. In the scenario described, unused features are deactivated but remain in the codebase, fitting the exact definition of dead code. This practice increases the attack surface without providing functionality.Why the Other Options Are Wrong
Malicious code implies intentional harm, which isn't suggested by simple deactivation. Outsourced code refers to external development, not internal status. Code obfuscation involves making code hard to read, not merely leaving unused features present.Community Comment Notes
Community consensus strongly supports B, noting that dead code is present but unreachable. As one user noted, "Dead code refers to portions of a program's source code that are never executed." Another added, "code that is present in the codebase but is no longer executed or reachable."Exam Strategy
When analyzing software security questions, always distinguish between code that is intentionally hidden (obfuscation) and code that is simply unused (dead). Remember that unused code still consumes resources and may contain vulnerabilities.
Frequently Asked Questions
What is the difference between dead code and obfuscated code?
Dead code is unused and unexecuted, while obfuscated code is intentionally made difficult to understand for security.
Why is dead code a security concern?
It increases the attack surface and may contain undiscovered vulnerabilities that attackers can exploit.
