Question 152

A company has an ecommerce application that users access through multiple mobile apps and web applications. The company needs a solution that will receive requests from the mobile apps and web applications through an API.

Request traffic volume varies significantly throughout each day. Traffic spikes during sales events. The solution must be loosely coupled and ensure that no requests are lost.

Options:

Create an Application Load Balancer (ALB). Create an AWS Elastic Beanstalk endpoint to process the requests. Add the Elastic Beanstalk endpoint to the target group of the ALB.

Set up an Amazon API Gateway REST API with an integration to an Amazon Simple Queue Service (Amazon SQS) queue. Configure a dead-letter queue. Create an AWS Lambda function to poll the queue to process the requests.

Create an Application Load Balancer (ALB). Create an AWS Lambda function to process the requests. Add the Lambda function as a target of the ALB.

Set up an Amazon API Gateway HTTP API with an integration to an Amazon Simple Notification Service (Amazon SNS) topic. Create an AWS Lambda function to process the requests. Subscribe the function to the SNS topic to process the requests.

Question 153

A company needs to give a globally distributed development team secure access to the company's AWS resources in a way that complies with security policies.

The company currently uses an on-premises Active Directory for internal authentication. The company uses AWS Organizations to manage multiple AWS accounts that support multiple projects.

The company needs a solution to integrate with the existing infrastructure to provide centralized identity management and access control.

Which solution will meet these requirements with the LEAST operational overhead?

Options:

Set up AWS Directory Service to create an AWS managed Microsoft Active Directory on AWS. Establish a trust relationship with the on-premises Active Directory. Use IAM roles that are assigned to Active Directory groups to access AWS resources within the company's AWS accounts.

Create an IAM user for each developer. Manually manage permissions for each IAM user based on each user's involvement with each project. Enforce multi-factor authentication (MFA) as an additional layer of security.

Use AD Connector in AWS Directory Service to connect to the on-premises Active Directory. Integrate AD Connector with AWS IAM Identity Center. Configure permissions sets to give each AD group access to specific AWS accounts and resources.

Use Amazon Cognito to deploy an identity federation solution. Integrate the identity federation solution with the on-premises Active Directory. Use Amazon Cognito to provide access tokens for developers to access AWS accounts and resources.

Question 154

A company needs to design a resilient web application to process customer orders. The web application must automatically handle increases in web traffic and application usage without affecting the customer experience or losing customer orders.

Which solution will meet these requirements?

Options:

Use a NAT gateway to manage web traffic. Use Amazon EC2 Auto Scaling groups to receive, process, and store processed customer orders. Use an AWS Lambda function to capture and store unprocessed orders.

Use a Network Load Balancer (NLB) to manage web traffic. Use an Application Load Balancer to receive customer orders from the NLB. Use Amazon Redshift with a Multi-AZ deployment to store unprocessed and processed customer orders.

Use a Gateway Load Balancer (GWLB) to manage web traffic. Use Amazon Elastic Container Service (Amazon ECS) to receive and process customer orders. Use the GWLB to capture and store unprocessed orders. Use Amazon DynamoDB to store processed customer orders.

Use an Application Load Balancer to manage web traffic. Use Amazon EC2 Auto Scaling groups to receive and process customer orders. Use Amazon Simple Queue Service (Amazon SQS) to store unprocessed orders. Use Amazon RDS with a Multi-AZ deployment to store processed customer orders.

I think I'll give Cramkey a try next time I take a certification exam. Thanks for the recommendation!

Nadia

Why these dumps are important? Can I pass my exam without these dumps?

Julian Nov 14, 2025

The questions in the Cramkey dumps are explained in detail and there are also study notes and reference materials provided. This made it easier for me to understand the concepts and retain the information better.

Nylah

I've been looking for good study material for my upcoming certification exam. Need help.

Dolly Nov 17, 2025

Then you should definitely give Cramkey Dumps a try. They have a huge database of questions and answers, making it easy to study and prepare for the exam. And the best part is, you can be sure the information is accurate and relevant.

Aliza

I used these dumps for my recent certification exam and I can say with certainty that they're absolutely valid dumps. The questions were very similar to what came up in the actual exam.

Jakub Nov 11, 2025

That's great to hear. I am going to try them soon.

Question 155

A solutions architect is designing a system to be highly resilient. The system uses Amazon Route 53 with health checks and an Application Load Balancer (ALB). The system is critical and must have the highest availability possible.

Options:

Automate failover to a healthy resource by automatically updating the value of the Route 53 A record.

Configure the Route 53 health checks to perform a failover automatically.

Automate failover to a healthy resource by updating the weight of the Route 53 weighted record.

Create a new ALB during a failover event, and remap the target group to the new ALB.
