  1. pavan says:

    Option A: NAT instance doesn’t make a sense here
    Option E: ELB with an EIP (we assign EIP’s to instances)

    So A&E are ruled out. Choosing between B,C & D
    Option B is wrong as it says “origin to point to the private IP addresses of your
    Web servers” (Private IP Address pointing)

    So Answer –> C&D

    C is possible if the domain is not an apex domain and hence C is feasible assuming website will start with subdomain http://WWW.domainname.com
    D is feasible

    I am not sure if Cloudfront can talk to any AWS resource on private IPs. If yes B could have been a more approprate response

      I sure hope the actual exam has fewer typos (or scanning errors). I was trying to figure out how we assign British Petroleum to all of the web servers.
