A company launched an Amazon EC2 instance with the latest Amazon Linux 2 Amazon Machine Image (AMI). Which actions can a system administrator take to connect to the EC2 instance? (Choose two.)
A.
Use Amazon EC2 Instance Connect.
B.
Use a Remote Desktop Protocol (RDP) connection.
A. Use Amazon EC2 Instance Connect.
Amazon EC2 Instance Connect allows you to connect securely to your Amazon EC2 instances using the AWS Management Console or the AWS Command Line Interface (CLI). It eliminates the need to manage and share SSH keys manually and provides a more secure way to access instances.
D. Use AWS Systems Manager Session Manager.
AWS Systems Manager Session Manager allows you to start interactive sessions with your instances directly from the AWS Management Console or through the AWS CLI. It provides secure and auditable access to instances without the need to open inbound SSH ports.
C: AWS Batch is a fully managed batch computing service that lets you run hundreds of thousands of batch and machine learning (ML) jobs across various AWS compute offerings
Seriously, why so many wrong answers?
A. Amazon EC2 Instance Connect is a secure and easy-to-use method for SSH access to EC2 instances. It allows system administrators to connect to their instances using the AWS Management Console or the AWS CLI without the need for managing SSH key pairs manually.
D. AWS Systems Manager Session Manager provides interactive shell access to EC2 instances directly from the AWS Management Console or the AWS CLI. It does not require opening inbound SSH ports or managing SSH keys.
You can use Amazon EC2 Instance Connect (option A) to connect to an EC2 instance . Amazon EC2 Instance Connect provides a simple and secure way to connect to your instances using Secure Shell (SSH). You can also use AWS Systems Manager Session Manager (option D) to connect to an EC2 instance . AWS Systems Manager Session Manager is a fully managed AWS Systems Manager capability that lets you manage your Amazon EC2 instances through an interactive one-click browser-based shell or through the AWS CLI.
A. Use Amazon EC2 Instance Connect: This is a browser-based SSH connection method that allows you to connect to your EC2 instances using AWS Identity and Access Management (IAM) credentials, without the need to manage SSH keys. You can use Instance Connect to connect to an instance using the EC2 console, AWS CLI, or SDKs.
D. Use AWS Systems Manager Session Manager: This is a fully-managed, secure, and auditable way to access your instances using the AWS Systems Manager console or AWS CLI. With Session Manager, you can tunnel your SSH (Secure Shell) and SCP (Secure Copy) connections to your instances, without requiring inbound connections or the use of bastion hosts or VPNs.
Cant see see how the answer can be A and C, AWS Batch manages compute environments and job queues, allowing you to easily run thousands of jobs of any scale using Amazon ECS, Amazon EKS, and AWS Fargate with an option between Spot or on-demand resources. You simply define and submit your batch jobs to a queue
