Topic 1 Question 323
A user is connected to an Amazon EC2 instance in a private subnet. The user is unable to access the internet from the instance by using the following curl command: curl http:/www.example.com.
A SysOps administrator reviews the VPC configuration and learns the following information:
• The private subnet has a route to a NAT gateway for CIDR 0.0.0.0/0 • The outbound security group for the EC2 instance contains one rule: outbound for port 443 to CIDR 0.0.0.0/0 • The inbound security group for the EC2 instance allows ports 22 and 443 from the user's IP address. • The inbound network ACL for the subnet allows port 22 and port range 1024-65535 from CIDR 0.0.0.0/0
Which action will allow the user to complete the curl request successfully?
Add an additional inbound network ACL rule for port 80 to CIDR 0.0.0.0/0.
Add an additional inbound security group rule for port 80 to CIDR 0.0.0.0/0.
Add an additional outbound security group rule for port 80 to CIDR 0.0.0.0/0.
Add an additional outbound security group rule for port 80 to the user's IP address.

C is correct as curl was being used to go to http and port 80 is not in the allowed outbound yet.
👍 4mh82023/07/22 curl = outbound http:/www.example.com = port 80
