A customer has an instance hosted in the AWS Public Cloud. The VPC and subnet used to host the Instance have been created with the default settings for the Network Access Control Lists. They need to provide an IT Administrator secure access to the underlying instance.
How can this be accomplished?
A . Ensure the Network Access Control Lists allow Inbound SSH traffic from the IT Administrator’s Workstation
B . Ensure the Network Access Control Lists allow Outbound SSH traffic from the IT Administrator’s Workstation
C . Ensure that the security group allows Inbound SSH traffic from the IT Administrator’s Workstation
D . Ensure that the security group allows Outbound SSH traffic from the IT Administrator’s Workstation
Answer: C
Explanation:
Options A & B are invalid as default NACL rule will allow all inbound and outbound traffic.
The requirement is that the IT administrator should be able to access this EC2 instance from his workstation. For that we need to enable the Security Group of EC2 instance to allow traffic from the IT administrator’s workstation. Hence option C is correct.
Option D is incorrect as we need to enable the Inbound SSH traffic on the EC2 instance Security Group since the traffic originate’, from the IT admin’s workstation.
The correct answer is: Ensure that the security group allows Inbound SSH traffic from the IT Administrator’s Workstation Submit your Feedback/Queries to our Experts
