All IP Addresses Within a 10

question 58

Multiple Choice

All IP addresses within a 10.0.0.0/16 VPC are fully utilized with application servers across two Availability Zones. The application servers need to send frequent UDP probes to a single central authentication server on the Internet to confirm that it is running up-to-date packages. The network is designed for application servers to use a single NAT gateway for internal access. Testing reveals that a few of the servers are unable to communicate with the authentication server. What is the reason for this failure?

• A) The NAT gateway does not support UDP traffic.
• B) The authentication server is not accepting traffic.
• C) The NAT gateway cannot allocate more ports.
• D) The NAT gateway is launched in a private subnet.
