A SysOps administrator migrates NAT instances to NAT gateways.After the migration, an application that is hosted on Amazon EC2 instances in a private subnet cannot access the internet.
Which of the following are possible reasons for this problem?
(Choose two.)
The application is using a protocol that the NAT gateway does not support.
The NAT gateway is not in a security group.
The NAT gateway is in an unsupported Availability Zone.
The NAT gateway is not in the Available state.
The port forwarding settings do not allow access to internal services from the internet.
I draft that the answer is:
The application is using a protocol that the NAT gateway does not support.
