A security learn needs to enforce the rotation of all IAM users' access keys every 90 days If an access key Is found to be older, the key must be made inactive and removed A solutions architect must create a solution that will check for and remediate any keys older than 90 days Which solution meets these requirements with the LEAST operational effort?

• A.Create an AWS Config rule to check for the key age Configure the AWS Config rule to run an AWS Batch job to remove the key
• B.Create an Amazon EventBridge (Amazon CloudWatch Events) rule to check for the key age Configure the rule to run an AWS Batch job to remove the key
• C.Create an AWS Config rule to check for the key age Define an Amazon EventBridge (Amazon CloudWatch Events) rule to schedule an AWS Lambda function to remove the key
• D.Create an Amazon EventBridge (Amazon CloudWatch Events) rule to check for the key age Define an EventBridge (CloudWatch Events) rule to run an AWS Batch job to remove the key

A company runs an internal browser-based application The application runs on Amazon EC2 instances behind an Application Load Balancer The instances run in an Amazon EC2 Auto Scaling group across multiple Availability Zones The Auto Scaling group scales up to 20 instances during work hours, but scales down to 2 instances overnight Staff are complaining that the application is very slow when the day begins, although it runs well by mid-morning.
How should the scaling be changed to address the staff complaints and keep costs to a minimum?

• A.Implement a scheduled action that sets the minimum and maximum capacity to 20 shortly before the office opens
• B.Implement a scheduled action that sets the desired capacity to 20 shortly before the office opens
• C.Implement a target tracking action triggered at a lower CPU threshold and decrease the cooldown period
• D.Implement a step scaling action triggered at a lower CPU threshold, and decrease the cooldown period.

A news company that has reporters ail over the world is hosting its broadcast system on AWS The reporters send live broadcasts to the broadcast system The reporters use software on their phones to send live streams through the Real Time Messaging Protocol (RTMP).
A solutions architect must design a solution that gives the reporters the ability to send the highest quality streams. The solution must provide accelerated TCP connections back to the broadcast system.
What should the solutions a use to meet these requirements?

• A.AWS Global Accelerator
• B.Amazon CloudFront
• C.Amazon EC2 Instances and AWS Elastic IP addresses
• D.AWS Client VPN

A company is migrating a large, mission-critical database to AWS. A solutions architect has decided to use an Amazon RDS for MySQL Multi-AZ DB instance that Is deployed with 80,000 Provisioned IOPS for storage The solutions architect is using AWS Database Migration Service (AWS DMS) to perform the data migration. The migration is taking longer than expected, and the company wants to speed up the process. The company's network team has ruled out bandwidth as a limiting factor.
Which actions should the solutions architect take to speed up the migration? (Select TWO.)

• A.Change the storage type on the target DB instance to Amazon Elastic Block Store (Amazon EBS) General Purpose SSD (gp2).
• B.Restart the DMS task on a new DMS instance with transfer acceleration enabled.
• C.Create a new DMS instance that has a larger instance size.
• D.Disable Multi-AZ on the target DB instance.
• E.Turn off logging on the target DB instance until the initial load is complete.

A company is designing a new multi-tier web application that consists of the following components:
* Web and application servers that run on Amazon EC2 instances as part of Auto Scaling groups
* An Amazon RDS DB instance for data storage
A solutions architect needs to limit access to the application servers so that only the web servers can access them Which solution will meet these requirements?

• A.Deploy a Network Load Balancer with a target group that contains the application servers" Auto Scaling group. Configure the network ACL to allow only the web servers to access the application servers
• B.Deploy AWS PrivateLink in front of the application servers Configure the network ACL to allow only the web servers to access the application servers
• C.Deploy a VPC endpoint in front of the application servers Configure the security group to allow only the web servers to access the application servers
• D.Deploy an Application Load Balancer with a target group that contains the application servers' Auto Scaling group Configure the security group to allow only the web servers to access the application servers.
