A company has a web server running on an Amazon EC2 instance in a public subnet with an Elastic IP address. The default security group is assigned to the EC2 instance. The default network ACL has been modified to block all traffic. A solutions architect needs to make the web server accessible from everywhere on port 443. Which combination of steps will accomplish this task? (Choose two.)

A.
Create a security group with a rule to allow TCP port 443 from source 0.0.0.0/0.
Answers
A.
Create a security group with a rule to allow TCP port 443 from source 0.0.0.0/0.
B.
Create a security group with a rule to allow TCP port 443 to destination 0.0.0.0/0.
Answers
B.
Create a security group with a rule to allow TCP port 443 to destination 0.0.0.0/0.
C.
Update the network ACL to allow TCP port 443 from source 0.0.0.0/0.
Answers
C.
Update the network ACL to allow TCP port 443 from source 0.0.0.0/0.
D.
Update the network ACL to allow inbound/outbound TCP port 443 from source 0.0.0.0/0 and to destination 0.0.0.0/0.
Answers
D.
Update the network ACL to allow inbound/outbound TCP port 443 from source 0.0.0.0/0 and to destination 0.0.0.0/0.
E.
Update the network ACL to allow inbound TCP port 443 from source 0.0.0.0/0 and outbound TCP port 32768-65535 to destination 0.0.0.0/0.
Answers
E.
Update the network ACL to allow inbound TCP port 443 from source 0.0.0.0/0 and outbound TCP port 32768-65535 to destination 0.0.0.0/0.
Suggested answer: A, C

Explanation:

The combination of steps that will accomplish the task of making the web server accessible from everywhere on port 443 is to create a security group with a rule to allow TCP port 443 from source 0.0.0.0/0 (A) and to update the network ACL to allow inbound TCP port 443 from source 0.0.0.0/0 (C). This will ensure that traffic to port 443 is allowed both at the security group level and at the network ACL level, which will make the web server accessible from everywhere on port 443.
