Which of the below mentioned options is not a possible reason for rejection?
The access key to connect to the instance is wrong
The security group is not configured properly
The private key used to launch the instance is not correct
The instance CPU is heavily loaded
Explanations:
If the access key to connect is wrong, the SSH connection will fail, but this would typically result in an authentication error, not a connection timeout.
If the security group is not configured properly, it could block inbound traffic (SSH) and lead to a connection timeout.
If the private key used to launch the instance is not correct, the SSH connection would fail due to authentication errors, but not necessarily a timeout.
A heavily loaded CPU would not typically cause a connection timeout; it may slow down the instance, but a timeout is more likely to be caused by network issues, not CPU load.
