Question 28

A company is running an application in the AWS Cloud. Recent application metrics show inconsistent response times and a significant increase in error rates. Calls to third-party services are causing the delays. Currently, the application calls third-party services synchronously by directly invoking an AWS Lambda function.

A solutions architect needs to decouple the third-party service calls and ensure that all the calls are eventually completed.

Which solution will meet these requirements?

Options:

Use an Amazon Simple Queue Service (Amazon SQS) queue to store events and invoke the Lambda function.

Use an AWS Step Functions state machine to pass events to the Lambda function.

Use an Amazon EventBridge rule to pass events to the Lambda function.

Use an Amazon Simple Notification Service (Amazon SNS) topic to store events and Invoke the Lambda function.

Question 29

A company recently started hosting new application workloads in the AWS Cloud. The company is using Amazon EC2 instances, Amazon Elastic File System (Amazon EFS) file systems, and Amazon RDS DB instances.

To meet regulatory and business requirements, the company must make the following changes for data backups:

* Backups must be retained based on custom daily, weekly, and monthlyrequirements.

* Backups must be replicated to at least one other AWS Region immediately after capture.

* The backup solution must provide a single source of backup status across the AWS environment.

* The backup solution must send immediate notifications upon failure of any resource backup.

Which combination of steps will meet this requirement with the LEAST amount of operational overhead? (Select THREE.)

Options:

Create an AWS Backup plan with a backup rule for each of the retention requirements.

Configure an AWS backup plan to copy backups to another Region.

Create an AWS Lambda function to replicate backups to another Region and send notification if a failure occurs.

Add an Amazon Simple Notification Service (Amazon SNS) topic to the backup plan to send a notification for finished jobs that have any status except BACKUP- JOB- COMPLETED.

Create an Amazon Data Lifecycle Manager (Amazon DLM) snapshot lifecycle policy for each of the retention requirements.

Set up RDS snapshots on each database.

Anaya

I found so many of the same questions on the real exam that I had already seen in the Cramkey Dumps. Thank you so much for making exam so easy for me. I passed it successfully!!!

Nina Sep 9, 2025

It's true! I felt so much more confident going into the exam because I had already seen and understood the questions.

Mariam

Do anyone think Cramkey questions can help improve exam scores?

Katie Sep 14, 2025

Absolutely! Many people have reported improved scores after using Cramkey Dumps, and there are also success stories of people passing exams on the first try. I already passed this exam. I confirmed above questions were in exam.

Carson

Yeah, definitely. I would definitely recommend Cramkey Dumps to anyone who is preparing for an exam.

Rufus Sep 9, 2025

Me too. They're a lifesaver!

Pippa

I was so happy to see that almost all the questions on the exam were exactly what I found in their Dumps.

Anastasia Sep 17, 2025

You are right…It was amazing! The Cramkey Dumps were so comprehensive and well-organized, it made studying for the exam a breeze.

Neve

Will I be able to achieve success after using these dumps?

Rohan Sep 27, 2025

Absolutely. It's a great way to increase your chances of success.

Question 30

A company has a multi-tier web application that runs on a fleet of Amazon EC2 instances behind an Application Load Balancer (ALB). The instances are in an Auto Scaling group. The ALB and the Auto Scaling group are replicated in a backup AWS Region. The minimum value and the maximum value for the Auto Scaling group are set to zero. An Amazon RDS Multi-AZ DB instance stores the application’s data. The DB instance has a read replica in the backup Region. The application presents an endpoint to end users by using an Amazon Route 53 record.

The company needs to reduce its RTO to less than 15 minutes by giving the application the ability to automatically fail over to the backup Region. The company does not have a large enough budget for an active-active strategy.

What should a solutions architect recommend to meet these requirements?

Options:

Reconfigure the application’s Route 53 record with a latency-based routing policy that load balances traffic between the two ALBs. Create an AWS Lambda function in the backup Region to promote the read replica and modify the Auto Scaling group values. Create an Amazon CloudWatch alarm that is based on the HTTPCode_Target_5XX_Count metric for the ALB in the primary Region. Configure the CloudWatch alarm to invoke the Lambda function.

Create an AWS Lambda function in the backup Region to promote the read replica and modify the Auto Scaling group values. Configure Route 53 with a health check that monitors the web application and sends an Amazon Simple Notification Service (Amazon SNS) notification to the Lambda function when the health check status is unhealthy. Update the application’s Route 53 record with a failover policy that routes traffic to the ALB in the backup R

Configure the Auto Scaling group in the backup Region to have the same values as the Auto Scaling group in the primary Region. Reconfigure the application’s Route 53 record with a latency-based routing policy that load balances traffic between the two ALBs. Remove the read replica. Replace the read replica with a standalone RDS DB instance. Configure Cross-Region Replicationbetween the RDS DB instances by using snapshots and Amazon S3.

Configure an endpoint in AWS Global Accelerator with the two ALBs as equal weighted targets. Create an AWS Lambda function in the backup Region to promote the read replica and modify the Auto Scaling group values. Create an Amazon CloudWatch alarm that is based on the HTTPCode_Target_5XX_Count metric for the ALB in the primary Region. Configure the CloudWatch alarm to invoke the Lambda function.

Question 31

A company operates an on-premises software-as-a-service (SaaS) solution that ingests several files daily. The company provides multiple public SFTP endpoints to its customers to facilitate the file transfers. The customers add the SFTP endpoint IP addresses to their firewall allow list for outbound traffic. Changes to the SFTP endmost IP addresses are not permitted.

The company wants to migrate the SaaS solution to AWS and decrease the operational overhead of the file transfer service.

Which solution meets these requirements?

Options:

Register the customer-owned block of IP addresses in the company's AWS account. Create Elastic IP addresses from the address pool and assign them to an AWS Transfer for SFTP endpoint. Use AWS Transfer to store the files in Amazon S3.

Add a subnet containing the customer-owned block of IP addresses to a VPC Create Elastic IP addresses from the address pool and assign them to an Application Load Balancer (ALB). Launch EC2 instances hosting FTP services in an Auto Scaling group behind the ALB. Store the files in attached Amazon Elastic Block Store (Amazon EBS) volumes.

Register the customer-owned block of IP addresses with Amazon Route 53. Create alias records in Route 53 that point to a Network Load Balancer (NLB). Launch EC2 instances hosting FTP services in an Auto Scaling group behind the NLB. Store the files in Amazon S3.

Register the customer-owned block of IP addresses in the company's AWS account. Create Elastic IP addresses from the address pool and assign them to an Amazon S3 VPC endpoint. Enable SFTP support on the S3 bucket.
