4. The custom firewall should map the internal DNS with the elastic IP using NAT.

Correct Answer : Get Lastest Questions and Answer :
In Amazon Web Services, if a user is creating a custom firewall configuration in EC2-Classic, the user must allow inbound traffic from port 53 (with a destination port from the ephemeral range) from the address of the Amazon DNS server. Otherwise, the internal DNS resolution from the user's instances fails. If the firewall does not automatically allow the DNS query responses, then the user needs to allow traffic from the IP address of the Amazon DNS server. To get the IP address of the Amazon DNS server on Linux, use the following command: grep nameserver /etc/resolv.conf. To get the IP address of the Amazon DNS Server on Windows, use the following command: ipconfig /all | findstr /c:"DNS Servers".
