ATo reduce electricity consumption during attacks
BTo speed up system reboot times
CTo prevent both physical and digital spread of the attack
DTo allow attackers to access only physical devices
Step-by-Step Solution
Solution:

  1. Step 1: Define physical and network isolation

    Physical isolation means disconnecting hardware; network isolation means cutting off network access.

  2. Step 2: Understand combined effect

    Both prevent the attack from spreading through physical contact or network connections.

  3. Final Answer:

    To prevent both physical and digital spread of the attack -> Option C

  4. Quick Check:

    Physical + network isolation = block all spread [OK]
Quick Trick: Use both isolations to fully contain attacks [OK]
Common Mistakes:
MISTAKES
  • Thinking isolation speeds reboot
  • Assuming attackers gain access
