To answer this question, you need to understand the different design principles in software engineering. Let's go through each option to understand why it is correct or incorrect:
Option A) Least Privilege - This option is incorrect because least privilege refers to providing only the necessary access rights or permissions to users or processes. It is not directly related to enabling specific features in a web server.
Option B) Leveraging existing components - This option is incorrect because leveraging existing components refers to reusing or integrating existing software components or libraries to build new systems or applications. It is not directly related to enabling specific features in a web server.
Option C) Economy of mechanism - This option is correct because economy of mechanism refers to keeping the design of a system simple and minimal to reduce the chances of errors or failures. Using a custom build process to enable specific features in the Apache Web server aligns with this principle as it allows for a streamlined and efficient way to add only the necessary components or functionalities.
Option D) Fail safe - This option is incorrect because fail safe refers to designing a system or process in a way that minimizes the impact of failures or errors. It is not directly related to enabling specific features in a web server.
The correct answer is C. Using a custom build process to enable specific features in the Apache Web server aligns with the design principle of economy of mechanism as it keeps the design minimal and efficient.
