Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Global SSL Proxy Load Balancer
Why this is correct
Provides SSL termination for TCP traffic.
- ✗
Global TCP Proxy Load Balancer
Why it's wrong here
TCP Proxy does not provide SSL termination.
- ✗
Regional Internal HTTP(S) Load Balancer
Why it's wrong here
Internal L7 load balancer, not for external clients.
- ✗
Global HTTPS Load Balancer
Why it's wrong here
HTTPS LB does not preserve client IP by default and is for HTTP/S.
- ✓
Regional External TCP/UDP Network Load Balancer
Why this is correct
The Regional External TCP/UDP Network Load Balancer preserves client IP addresses by operating at layer 4 without terminating the TCP connection, forwarding packets directly to backends so the original source IP remains visible to the application. This satisfies the stem’s constraint of preserving client IPs for the legacy TCP application. It does not provide SSL termination, which is handled separately by a different load balancer.
