Question in Section-Based – Network Implementation

[saig1991]

There are several publicly-accessible applications that are being developed and maintained by a software development company. Some applications are hosted on Amazon EC2 Dedicated Hosts while others are running in an Auto Scaling group of EC2 instances behind an Application Load Balancer. Amazon CloudFront web distributions with geo-restriction feature enabled are also used to prevent users in specific geographic locations from accessing the site contents. To generate data analytics, the Network Team must get the IP addresses of the users who are visiting these web applications.

Which of the following are true regarding the process of retrieving the client IP address? (Select THREE.)

Correct the answer here:, Here, it’s the First IP address in the X-Forwarded-For belongs to the user’s location. It’s not the not IP address in the HTTP header.

The last IP address in the X-Forwarded-For HTTP header is most likely associated with the user’s geographic location. This header typically contains more than one IP address, most of which are for proxies or load balancers.
