Exam AWS Certified Solutions Architect - Professional SAP-C02 topic 1 question 321 discussion

Exam question from Amazon's AWS Certified Solutions Architect - Professional SAP-C02
Question #: 321
Topic #: 1
[All AWS Certified Solutions Architect - Professional SAP-C02 Questions]

A research company is running daily simulations in the AWS Cloud to meet high demand. The simulations run on several hundred Amazon EC2 instances that are based on Amazon Linux 2. Occasionally, a simulation gets stuck and requires a cloud operations engineer to solve the problem by connecting to an EC2 instance through SSH.

Company policy states that no EC2 instance can use the same SSH key and that all connections must be logged in AWS CloudTrail.

How can a solutions architect meet these requirements?

  • A. Launch new EC2 instances, and generate an individual SSH key for each instance. Store the SSH key in AWS Secrets Manager. Create a new IAM policy, and attach it to the engineers’ IAM role with an Allow statement for the GetSecretValue action. Instruct the engineers to fetch the SSH key from Secrets Manager when they connect through any SSH client.
  • B. Create an AWS Systems Manager document to run commands on EC2 instances to set a new unique SSH key. Create a new IAM policy, and attach it to the engineers’ IAM role with an Allow statement to run Systems Manager documents. Instruct the engineers to run the document to set an SSH key and to connect through any SSH client.
  • C. Launch new EC2 instances without setting up any SSH key for the instances. Set up EC2 Instance Connect on each instance. Create a new IAM policy, and attach it to the engineers’ IAM role with an Allow statement for the SendSSHPublicKey action. Instruct the engineers to connect to the instance by using a browser-based SSH client from the EC2 console.
  • D. Set up AWS Secrets Manager to store the EC2 SSH key. Create a new AWS Lambda function to create a new SSH key and to call AWS Systems Manager Session Manager to set the SSH key on the EC2 instance. Configure Secrets Manager to use the Lambda function for automatic rotation once daily. Instruct the engineers to fetch the SSH key from Secrets Manager when they connect through any SSH client.

Selected Answer: C
Answer C is correct with the following reasons: The keywords: "no EC2 instance can use the same SSH key" AND " all connections must be logged in AWS CloudTrail." 1. EC2 Instance connect using temporary ssh key, one-time SSH keys each time the user connects 2. User connections via EC2 Instance Connect are logged to AWS CloudTrail

D Why not D. In C with instance connect, there are 100s of instances and key would be created for each instance manually would take lot of time
