A Development team has built an experimental environment to test a simple static web application. It has built an isolated VPC with a private and a public subnet. The public subnet holds only an Application Load Balancer, a NAT gateway, and an internet gateway. The private subnet holds all of the Amazon EC2 instances. There are 3 different types of servers. Each server type has its own Security Group that limits access to only required connectivity. The Security Groups have both inbound and outbound rules applied. Each subnet has both inbound and outbound network ACLs applied to limit access to only required connectivity. Which of the following should the team check if a server cannot establish an outbound connection to the internet? (Choose three.)
