Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓

A Load Balancer can serve as an SSL termination point, allowing the security team to inspect traffic for malware at a single, centralized ingress point.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Automatically patch all backend servers.
Why it's wrong here
Load balancers do not patch servers.
- ✗
Remove the need for host-based firewalls.
Why it's wrong here
Defense in depth requires host-based firewalls regardless of LB presence.
- ✗
Encrypt all backend data at rest.
Why it's wrong here
Load balancers handle transit traffic, not at-rest data.
- ✓
Act as a centralized TLS termination and traffic inspection point.
Why this is correct
Centralized inspection is a standard security design pattern.
