[All ANS-C01 Questions]

A Network Engineer is provisioning a subnet for a load balancer that will sit in front of a fleet of application servers in a private subnet. There is limited IP space left in the VPC CIDR. The application has few users now but is expected to grow quickly to millions of users.

What design will use the LEAST amount of IP space, while allowing for this growth?

I'd go with option B. A single /29 subnet for the Network Load Balancer now, and adding a new VPC CIDR later for future growth seems like a prudent and efficient approach. Plus, who doesn't love a good 'Network Load Balancer' pun?

I see your point, Moon. But I think option C is the most efficient with two /28 subnets for a Network Load Balancer in different Availability Zones.

I disagree, I believe option B is better as it allows for future growth by adding another VPC CIDR.

Hmm, option C looks like the way to go. Two /28 subnets for the Network Load Balancer should give us plenty of room to grow without wasting IP space. I'm impressed by your foresight, fellow engineer!

I think option A is the best choice because it uses the least amount of IP space.
