AWS Certified Solutions Architect - Associate (SAA-C03) Questions and Answers

Question 65

A company runs an order management application on AWS. The application allows customers to place orders and pay with a credit card. The company uses an Amazon CloudFront distribution to deliver the application. A security team has set up logging for all incoming requests. The security team needs a solution to generate an alert if any user modifies the logging configuration.

Which combination of solutions will meet these requirements? (Select TWO.)

Options:

A.

Configure an Amazon EventBridge rule that is invoked when a user creates or modifies a CloudFront distribution. Add the AWS Lambda function as a target of the EventBridge rule.

B.

Create an Application Load Balancer (ALB). Enable AWS WAF rules for the ALB. Configure an AWS Config rule to detect security violations.

C.

Create an AWS Lambda function to detect changes in CloudFront distribution logging. Configure the Lambda function to use Amazon Simple Notification Service (Amazon SNS) to send notifications to the security team.

D.

Set up Amazon GuardDuty. Configure GuardDuty to monitor findings from the CloudFront distribution. Create an AWS Lambda function to address the findings.

E.

Create a private API in Amazon API Gateway. Use AWS WAF rules to protect the private API from common security problems.

Question 66

A company is designing a website that displays stock market prices to users. The company wants to use Amazon ElastiCache (Redis OSS) for the data caching layer. The company needs to ensure that the website's data caching layer can automatically fail over to another node if necessary.

Options:

A.

Enable read replicas in ElastiCache (Redis OSS). Promote the read replica when necessary.

B.

Enable Multi-AZ in ElastiCache (Redis OSS). Fail over to a second node when necessary.

C.

Export a backup of the ElastiCache (Redis OSS) cache to an Amazon S3 bucket. Restore the cache to a second cluster when necessary.

D.

Export a backup of the ElastiCache (Redis OSS) cache by using AWS Backup. Restore the cache to a second cluster when necessary.

Question 67

A company runs HPC workloads requiring high IOPS.

Which combination of steps will meet these requirements? (Select TWO)

Options:

A.

Use Amazon EFS as a high-performance file system.

B.

Use Amazon FSx for Lustre as a high-performance file system.

C.

Create an Auto Scaling group of EC2 instances. Use Reserved Instances. Configure a spread placement group. Use AWS Batch for analytics.

D.

Use Mountpoint for Amazon S3 as a high-performance file system.

E.

Create an Auto Scaling group of EC2 instances. Use mixed instance types and a cluster placement group. Use Amazon EMR for analytics.

Question 68

A company has an application with a REST-based interface that allows data to be received in near-real time from a third-party vendor. Once received, the application processes and stores the data for further analysis. The application is running on Amazon EC2 instances.

The third-party vendor has received many 503 Service Unavailable Errors when sending data to the application. When the data volume spikes, the compute capacity reaches its maximum limit and the application is unable to process all requests.

Which design should a solutions architect recommend to provide a more scalable solution?

Options:

A.

Use Amazon Kinesis Data Streams to ingest the data. Process the data using AWS Lambda functions.

B.

Use Amazon API Gateway on top of the existing application. Create a usage plan with a quota limit for the third-party vendor.

C.

Use Amazon Simple Notification Service (Amazon SNS) to ingest the data. Put the EC2 instances in an Auto Scaling group behind an Application Load Balancer.

D.

Repackage the application as a container. Deploy the application using Amazon Elastic Container Service (Amazon ECS) using the EC2 launch type with an Auto Scaling group.
