Question 28

A company's packaged application dynamically creates and returns single-use text files in response to user requests. The company is using Amazon CloudFront for distribution, but wants to further reduce data transfer costs. The company cannot modify the application's source code.

What should a solutions architect do to reduce costs?

Options:

Use Lambda@Edge to compress the files as they are sent to users.

Enable Amazon S3 Transfer Acceleration to reduce the response times.

Enable caching on the CloudFront distribution to store generated files at the edge.

Use Amazon S3 multipart uploads to move the files to Amazon S3 before returning them to users.

Sarah

Yeah, I was so relieved when I saw that the question appeared in the exam were similar to their exam dumps. It made the exam a lot easier and I felt confident going into it.

Aaliyah Oct 22, 2025

Same here. I've heard mixed reviews about using exam dumps, but for us, it definitely paid off.

Melody

My experience with Cramkey was great! I was surprised to see that many of the questions in my exam appeared in the Cramkey dumps.

Colby Oct 24, 2025

Yes, In fact, I got a score of above 85%. And I attribute a lot of my success to Cramkey's dumps.

Inaya

Passed the exam. questions are valid. The customer support is top-notch. They were quick to respond to any questions I had and provided me with all the information I needed.

Cillian Oct 9, 2025

That's a big plus. I've used other dump providers in the past and the customer support was often lacking.

Cody

I used Cramkey Dumps to prepare and a lot of the questions on the exam were exactly what I found in their study materials.

Eric Oct 26, 2025

Really? That's great to hear! I used Cramkey Dumps too and I had the same experience. The questions were almost identical.

Question 29

A company runs multiple workloads in separate AWS environments. The company wants to optimize its AWS costs but must maintain the same level of performance for the environments.

The company's production environment requires resources to be highly available. The other environments do not require highly available resources.

Each environment has the same set of networking components, including the following:

• 1 VPC

• 1 Application Load Balancer

• 4 subnets distributed across 2 Availability Zones (2 public subnets and 2 private subnets)

• 2 NAT gateways (1 in each public subnet)

• 1 internet gateway

Which solution will meet these requirements?

Options:

Do not change the production environment workload. For each non-production workload, remove one NAT gateway and update the route tables for private subnets to target the remaining NAT gateway for the destination 0.0.0.0/0.

Reduce the number of Availability Zones that all workloads in all environments use.

Replace every NAT gateway with a t4g.large NAT instance. Update the route tables for each private subnet to target the NAT instance that is in the same Availability Zone for the destination 0.0.0.0/0.

In each environment, create one transit gateway and remove one NAT gateway. Configure routing on the transit gateway to forward traffic for the destination 0.0.0.0/0 to the remaining NAT gateway. Update private subnet route tables to target the transit gateway for the destination 0.0.0.0/0.

Question 30

A city's weather forecast team is using Amazon DynamoDB in the data tier for an application. The application has several components. The analysis component of the application requires repeated reads against a large dataset. The application has started to temporarily consume all the read capacity in the DynamoDB table and is negatively affecting other applications that need to access the same data.

Which solution will resolve this issue with the LEAST development effort?

Options:

Use DynamoDB Accelerator (DAX).

Use Amazon CloudFront in front of DynamoDB.

Create a DynamoDB table with a local secondary index (LSI).

Use Amazon ElastiCache in front of DynamoDB.

Question 31

A company has a three-tier web application. An Application Load Balancer (ALB) is in front of Amazon EC2 instances that are in the ALB target group. An Amazon S3 bucket stores documents.

The company requires the application to meet a recovery time objective (RTO) of 60 seconds.

Which solution will meet this requirement?

Options:

Replicate S3 objects to a second AWS Region. Create a second ALB and a minimum set of EC2 instances in the second Region. Ensure that the EC2 instances are shut down until they are needed. Configure Amazon Route 53 to fail over to the second Region by using an IP-based routing policy.

Use AWS Backup to take hourly backups of the EC2 instances. Back up the S3 data to a second AWS Region. Use AWS CloudFormation to deploy the entire infrastructure in the second Region when needed.

Create daily snapshots of the EC2 instances in a second AWS Region. Use the snapshots to recreate the instances in the second Region. Back up the S3 data to the second Region. Perform a failover by modifying the application DNS record when needed.

Replicate S3 objects to a second AWS Region. Create a second ALB and a minimum set of EC2 instances in the second Region. Ensure that the EC2 instances in the second Region are running. Configure Amazon Route 53 to fail over to the secondary Region based on health checks.
