A company runs applications in multiple AWS accounts in a single AWS Region. The accounts are members of an organization in AWS Organizations. The company is implementing security controls to manage cross-account access patterns in the company's AWS environment. The company wants to identify resources that might be unintentionally shared with external entities. The company wants to implement continuous monitoring for resource-based policies to detect external access. The company needs a solution that enforces multi-factor authentication (MFA) to assume cross-account IAM roles.
Which solution will meet these requirements?
A company is running an application in the AWS Cloud. The application collects and stores a large amount of unstructured data in an Amazon S3 bucket. The S3 bucket contains several terabytes of data and uses the S3 Standard storage class. The data increases in size by several gigabytes every day.
The company needs to query and analyze the data. The company does not access data that is more than 1-year-old. However, the company must retain all the data indefinitely for compliance reasons.
Which solution will meet these requirements MOST cost-effectively?
Generally, unstructured data should be converted structured data before querying them. AWS Glue can do that. https://docs.aws.amazon.com/glue/latest/dg/schema-relationalize.html https://docs.aws.amazon.com/athena/latest/ug/glue-athena.html
A company has used infrastructure as code (IaC) to provision a set of two Amazon EC2 instances. The instances have remained the same for several years.
The company's business has grown rapidly in the past few months. In response the company's operations team has implemented an Auto Scaling group to manage the sudden increases in traffic. Company policy requires a monthly installation of security updates on all operating systems that are running.
The most recent security update required a reboot. As a result, the Auto Scaling group terminated the instances and replaced them with new, unpatched instances.
Which combination of steps should a solutions architect recommend to avoid a recurrence of this issue? (Choose two.)
A company uses a load balancer to distribute traffic to Amazon EC2 instances in a single Availability Zone. The company is concerned about security and wants a solutions architect to re-architect the solution to meet the following requirements:
*Inbound requests must be filtered for common vulnerability attacks.
*Rejected requests must be sent to a third-party auditing application.
*All resources should be highly available.
Which solution meets these requirements?

A company has Linux-based Amazon EC2 instances. Users must access the instances by using SSH with EC2 SSH Key pairs. Each machine requires a unique EC2 Key pair.
The company wants to implement a key rotation policy that will, upon request, automatically rotate all the EC2 key pairs and keep the key in a securely encrypted place. The company will accept less than 1 minute of downtime during key rotation.
Which solution will meet these requirement?
To meet the requirements for automatic key rotation of EC2 SSH key pairs with minimal downtime, storing the keys in AWS Secrets Manager and defining a rotation schedule is the most suitable solution. AWS Secrets Manager supports automatic rotation of secrets, including SSH keys, by invoking a Lambda function that can handle the creation of new key pairs and the replacement of public keys on EC2 instances. Updating the corresponding private keys in Secrets Manager ensures secure and centralized management of SSH keys, complying with the key rotation policy and minimizing operational overhead.
AWS Secrets Manager Documentation: Describes how to store and rotate secrets, including SSH keys, using Secrets Manager and Lambda functions.
AWS Lambda Documentation: Provides information on creating Lambda functions for custom secret rotation logic.
AWS Best Practices for Security: Highlights the importance of key rotation and how AWS services like Secrets Manager can facilitate secure and automated key management.
