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

Question 93

A company needs to accommodate traffic for a web application that the company hosts on AWS, especially during peak usage hours.

The application uses Amazon EC2 instances as web servers, an Amazon RDS DB instance for database operations, and an Amazon S3 bucket to store transaction documents. The application struggles to scale effectively and experiences performance issues.

The company wants to improve the scalability of the application and prevent future performance issues. The company also wants to improve global access speeds to the transaction documents for the company's global users.

Which solution will meet these requirements?

Options:

A.

Place the EC2 instances in Auto Scaling groups to scale appropriately during peak usage hours. Use Amazon RDS read replicas to improve database read performance. Deploy an Amazon CloudFront distribution that uses Amazon S3 as the origin.

B.

Increase the size of the EC2 instances to provide more compute capacity. Use Amazon ElastiCache to reduce database read loads. Use AWS Global Accelerator to optimize the delivery of the transaction documents that are in the S3 bucket.

C.

Transition workloads from the EC2 instances to AWS Lambda functions to scale in response to the usage peaks. Migrate the database to an Amazon Aurora global database to provide cross-Region reads. Use AWS Global Accelerator to deliver the transaction documents that are in the S3 bucket.

D.

Convert the application architecture to use Amazon Elastic Container Service (Amazon ECS) containers. Configure a Multi-AZ deployment of Amazon RDS to support database operations. Replicate the transaction documents that are in the S3 bucket across multiple AWS Regions.

Question 94

A company is launching a new application that requires a structured database to store user profiles, application settings, and transactional data. The database must be scalable with application traffic and must offer backups.

Which solution will meet these requirements MOST cost-effectively?

Options:

A.

Deploy a self-managed database on Amazon EC2 instances by using open-source software. Use Spot Instances for cost optimization. Configure automated backups to Amazon S3.

B.

Use Amazon RDS. Use on-demand capacity mode for the database with General Purpose SSD storage. Configure automatic backups with a retention period of 7 days.

C.

Use Amazon Aurora Serverless for the database. Use serverless capacity scaling. Configure automated backups to Amazon S3.

D.

Deploy a self-managed NoSQL database on Amazon EC2 instances. Use Reserved Instances for cost optimization. Configure automated backups directly to Amazon S3 Glacier Flexible Retrieval.

Question 95

A software company needs to upgrade a critical web application. The application is hosted in a public subnet. The EC2 instance runs a MySQL database. The application's DNS records are published in an Amazon Route 53 zone.

A solutions architect must reconfigure the application to be scalable and highly available. The solutions architect must also reduce MySQL read latency.

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

Options:

A.

Launch a second EC2 instance in a second AWS Region. Use a Route 53 failover routing policy to redirect the traffic to the second EC2 instance.

B.

Create and configure an Auto Scaling group to launch private EC2 instances in multiple Availability Zones. Add the instances to a target group behind a new Application Load Balancer.

C.

Migrate the database to an Amazon Aurora MySQL cluster. Create the primary DB instance and reader DB instance in separate Availability Zones.

D.

Create and configure an Auto Scaling group to launch private EC2 instances in multiple AWS Regions. Add the instances to a target group behind a new Application Load Balancer.

E.

Migrate the database to an Amazon Aurora MySQL cluster with cross-Region read replicas.

Question 96

A global media streaming company is migrating its user authentication and content delivery services to AWS. The company wants to use Amazon API Gateway for user authentication and authorization. The company needs a solution that restricts API access to AWS Regions in the United States and ensures minimal latency.

Which solution will meet these requirements?

Options:

A.

Create an API Gateway REST API. Configure an AWS WAF firewall in the same Region. Implement AWS WAF rules to deny requests that originate from Regions outside the United States. Associate the AWS WAF firewall with the API Gateway REST API.

B.

Create an API Gateway HTTP API. Configure an AWS WAF firewall in a different Region. Implement AWS WAF rules to deny requests that originate from Regions outside the United States. Associate the AWS WAF firewall with the API Gateway HTTP API.

C.

Create an API Gateway REST API. Configure an AWS WAF firewall in a different Region. Implement AWS WAF rules to deny requests that originate from Regions outside the United States. Associate the AWS WAF firewall with the API Gateway REST API.

D.

Create an API Gateway HTTP API. Configure an AWS WAF firewall in the same Region. Implement AWS WAF rules to deny requests that originate from Regions outside the United States. Associate the AWS WAF firewall with the API Gateway HTTP API.
