An organization has multiple applications running in VPCs across multiple AWS accounts. The network engineer has deployed a central VPC with a pair of software VPN instances that run IPSec tunnels with dynamic routing to VGWs of all application VPCs.

The DDoS isn't a TCP attack.

You need to add a deny rule outbound also since NACLs are stateful.

Imagine you are using AWS Direct Connect with just one connection from your router to the AWS Direct Connect router. If your connection becomes unavailable, the communication with AWS cloud is lost. What is the best method to prevent this from happening?

AWS Direct Connect neither provides BGP nor provides the failover.

AWS Direct Connect recommends to have the same configuration set up in a multi AZ zone to prevent such loss in connections.

AWS Direct Connect recommends that you request and configure two dedicated connections to AWS either using BGP Multipath (Active/Active) connection or the failover (Active/Passive) connection.

AWS Direct connect does not have a provision to prevent the situation but when you design the system, it is recommended to request a back-up instance to which the traffic can be re-routed.

Question 114

A company wants to enforce a compliance requirement that its Amazon EC2 instances use only on-premises DNS servers for name resolution. Outbound DNS requests to all other name servers must be denied. A network engineer configures the following set of outbound rules for a security group:

The network engineer discovers that the EC2 instances are still able to resolve DNS requests by using Amazon DNS servers inside the VPC. Why is the solution failing to meet the compliance requirement?

The security group cannot filer outbound traffic to the Amazon DNS servers.

The security group must have inbound rules to prevent DNS requests from coming back to EC2 instances.

The EC2 instances are using the HTTPS port to send DNS queries to Amazon DNS servers.

The security group cannot filter outbound traffic to destinations within the same VPC.
