    This answer, to me, is worded in a confusing way.

    A DevOps Engineer reported a problem accessing his EC2 instance with a private IP address of 172.31.8.11 from his corporate laptop. The EC2 instance is hosting a web application which works well but he is still experiencing an issue establishing a connection to manage the instance.

    As the SysOps Administrator, which of the following options is the most suitable solution in this scenario based on the VPC flow log entries below?

    2 123456789010 eni-abc123de 110.217.100.70 172.31.8.11 49761 3389 6 20 4249 1418530010 1418530070 REJECT OK

    Answer:

    Allow incoming RDP traffic in the security group of the EC2 instance including the inbound and outbound rules in the Network ACL.

    If it were reworded to something like:

    Allow incoming RDP traffic in both the security group of the EC2 instance and the Network ACL inbound and outbound ruleset in the VPC.

    I feel that it’d be more clear that the VPC is where NACLs are configured. Thanks!
