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

Question 25

A company has an application that runs on a single Amazon EC2 instance. The application uses a MySQL database that runs on the same EC2 instance. The company needs a highly available and automatically scalable solution to handle increased traffic.

Which solution will meet these requirements?

Options:

A.

Deploy the application to EC2 instances that run in an Auto Scaling group behind an Application Load Balancer. Create an Amazon Redshift cluster that has multiple MySQL-compatible nodes.

B.

Deploy the application to EC2 instances that are configured as a target group behind an Application Load Balancer. Create an Amazon RDS for MySQL cluster that has multiple instances.

C.

Deploy the application to EC2 instances that run in an Auto Scaling group behind an Application Load Balancer. Create an Amazon Aurora Serverless MySQL cluster for the database layer.

D.

Deploy the application to EC2 instances that are configured as a target group behind an Application Load Balancer. Create an Amazon ElastiCache (Redis OSS) cluster that uses the MySQL connector.

Question 26

A security team needs to enforce rotation of all IAM users' access keys every 90 days. Keys older than 90 days must be automatically deactivated and removed. A solutions architect must create a remediation solution with minimal operational effort.

Which solution meets these requirements?

Options:

A.

Create an AWS Config rule to check key age. Configure the rule to run an AWS Batch job to remove the key.

B.

Create an Amazon EventBridge rule to check key age. Configure it to run an AWS Batch job to remove the key.

C.

Create an AWS Config rule to check key age. Define an EventBridge rule that schedules an AWS Lambda function to remove the key.

D.

Create an EventBridge rule to check key age. Define a second EventBridge rule to run an AWS Batch job to remove the key.

Question 27

A company wants to relocate its on-premises MySQL database to AWS. The database accepts regular imports from a client-facing application, which causes a high volume of write operations. The company is concerned that the amount of traffic might be causing performance issues within the application.

Options:

A.

Provision an Amazon RDS for MySQL DB instance with Provisioned IOPS SSD storage. Monitor write operation metrics by using Amazon CloudWatch. Adjust the provisioned IOPS if necessary.

B.

Provision an Amazon RDS for MySQL DB instance with General Purpose SSD storage. Place an Amazon ElastiCache cluster in front of the DB instance. Configure the application to query ElastiCache instead.

C.

Provision an Amazon DocumentDB (with MongoDB compatibility) instance with a memory-optimized instance type. Monitor Amazon CloudWatch for performance-related issues. Change the instance class if necessary.

D.

Provision an Amazon Elastic File System (Amazon EFS) file system in General Purpose performance mode. Monitor Amazon CloudWatch for IOPS bottlenecks. Change to Provisioned Throughput performance mode if necessary.

Question 28

A company hosts an industrial control application that receives sensor input through Amazon Kinesis Data Streams. The application needs to support new sensors for real-time anomaly detection in monitored equipment.

The company wants to integrate new sensors in a loosely-coupled, fully managed, and serverless way. The company cannot modify the application code.

Which solution will meet these requirements?

Options:

A.

Forward the existing stream in Kinesis Data Streams to Amazon Managed Service for Apache Flink for anomaly detection. Use a second stream in Kinesis Data Streams to send the Flink output to the application.

B.

Use Amazon Data Firehose to stream data to Amazon S3. Use Amazon Redshift Spectrum to perform anomaly detection on the S3 data. Use S3 Event Notifications to invoke an AWS Lambda function that sends analyzed data to the application through a second stream in Kinesis Data Streams.

C.

Configure Amazon EC2 instances in an Auto Scaling group to consume data from the data stream and to perform anomaly detection. Create a second stream in Kinesis Data Streams to send data from the EC2 instances to the application.

D.

Configure an Amazon Elastic Container Service (Amazon ECS) task that uses Amazon EC2 instances to consume data from the data stream and to perform anomaly detection. Create a second stream in Kinesis Data Streams to send data from the containers to the application.
