I had no idea it replaced the IP like that!

This is a common setup for load balancers.

Wait, really? I thought it could show the real IP.

That's correct, SLB does mask the client's IP.

I thought it was false since I believe there are ways to preserve the original IP address using X-Forwarded-For headers.

I recall that SLB can forward the real client IP if configured correctly, but I can't remember if that's the default behavior.

I'm not entirely sure, but I feel like there was a practice question about how SLB handles IP addresses, and it said something similar.

I think this is true because I remember reading that SLB acts as a proxy and modifies the headers.

This is a good question to think through. The key is understanding that SLB is operating at the layer 7 (HTTP) level, so it's modifying the HTTP header. The correct answer is therefore TRUE, as the backend ECS instance will see the SLB IP address, not the client's.

Wait, I'm a bit confused. If SLB is replacing the IP address in the HTTP header, wouldn't that mean the backend ECS instance wouldn't be able to see the client's real IP? I'm not sure if the TRUE or FALSE answer is correct here.

Okay, I think I've got this. Since the question states that SLB replaces the IP address in the HTTP header, the correct answer must be TRUE. The backend ECS instance will see the IP address of the SLB instead of the client's real IP.

Hmm, I'm a little unsure about this one. I know SLB is used for load balancing, but I'm not totally clear on how it handles the IP address in the HTTP header. I'll need to think this through carefully.

This seems pretty straightforward. The question is clearly asking about how Alibaba Cloud SLB handles the IP address in the HTTP header, so I'm confident I can answer this correctly.

Okay, I think I've got this. The key is that the compliance program needs to have multiple components, including a reporting system, accountability for management, and a dedicated compliance coordinator. I'll make sure to select the option that covers all those bases.
