When securing an AWS EC2 service directly with Palo Alto Networks NGFW, which component is responsible for address translation?

The correct choice indicates that both the server VMs and the Palo Alto Networks NGFW use private IP addresses, and it is Amazon's cloud infrastructure that is responsible for translating these addresses to publicly accessible IP addresses.

In an AWS environment, instances can be assigned private IP addresses, which are not routable on the internet, according to RFC 1918. This allows the instances to communicate securely within a private network while not exposing their internal IPs to the public internet. When instances need to access resources or be accessed from the internet, AWS employs Network Address Translation (NAT) to facilitate this process.

The AWS infrastructure effectively manages the translation of these private IP addresses to public IP addresses for communication outside the infrastructure, allowing for secure interactions with internet clients without directly exposing the internal addressing scheme. This setup is particularly important for maintaining the security and accessibility of services hosted in the cloud.

The other options do not accurately reflect the architecture and address translation mechanisms employed by AWS. They either suggest direct public accessibility of the server VMs or misattribute the address translation responsibility to the Palo Alto Networks NGFW, which does not manage external IP translation in this specific context. Instead, it functions more as a security appliance that can inspect and filter traffic before it
