Certified Information Systems Security Professional (CISSP) — Question 385

Which of the following is the MOST common method of memory protection?

Answer options

• A. Error correction
• B. Virtual local area network (VLAN) tagging
• C. Segmentation
• D. Compartmentalization

Correct answer: C

Explanation

Segmentation is the most common method of memory protection as it divides memory into segments, allowing for better management and access control. Error correction focuses on identifying and fixing data corruption rather than protecting memory. VLAN tagging is related to network segmentation, while compartmentalization is more about isolating resources rather than directly protecting memory.
