False, I believe it can show the real IP with proper config.

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

I think this is true because I practiced a similar question about how load balancers work with HTTP headers.

I remember studying how SLB handles IP addresses, but I'm not entirely sure if it always replaces the client's IP.

Okay, I think I've got it. The key here is that SLB is operating at the application layer, so it's replacing the IP in the HTTP header, not at the network layer. That means the backend will see SLB's IP, not the client's. I'm going with True on this one.

Wait, I'm a little confused. If SLB is forwarding the requests, shouldn't the backend ECS instance see the client's real IP address? I'm not sure if the statement about SLB replacing the IP is completely accurate. I'll have to re-read this a few times.

Easy peasy! The question says SLB will replace the client's IP address, so the correct answer has to be True. I'm confident I've got this one figured out.

This one seems pretty straightforward. The question is clearly stating that SLB replaces the client's IP address with its own, so I'm going with True.

Hmm, I'm a bit unsure about this one. The question is talking about layer 7 forwarding, but I'm not totally clear on how that affects the source IP address. I'll have to think this through carefully.

I'm pretty sure Manage-bde and the BitLocker control panel are the two tools we can use for BitLocker encryption. I've used them both before, so I feel confident about this one.

Haha, good thing I read this. I was about to start troubleshooting why my ECS instances weren't showing the client IPs. SLB to the rescue!

Wait, really? I thought SLB would pass the client's IP. This could be a problem if I need to track the actual source IP. *scratches head*

Ah, so that's why my ECS instances always show the SLB IP in the logs. Glad I don't have to worry about the real client IP.
