Which actions can a system administrator take to connect to the EC2 instance?
(Choose two.)
Use Amazon EC2 Instance Connect.
Use a Remote Desktop Protocol (RDP) connection.
Use AWS Batch.
Use AWS Systems Manager Session Manager.
Use Amazon Connect.
Explanations:
Amazon EC2 Instance Connect allows you to securely connect to an EC2 instance via SSH directly from the browser or through the AWS CLI, without requiring an SSH key pair.
RDP is used for Windows instances, not Amazon Linux 2 instances. For Linux instances, SSH is the common method to connect.
AWS Batch is a service for running batch jobs, not for connecting to EC2 instances.
AWS Systems Manager Session Manager enables secure, browser-based shell access to EC2 instances without needing an SSH key or open inbound ports.
Amazon Connect is a cloud-based contact center service, unrelated to EC2 instance connectivity.
As I see it, the answer is:
Use Amazon EC2 Instance Connect.
