Question 37

A company has deployed a web application on AWS. The company hosts the backend database on Amazon RDS for MySQL with a primary DB instance and five read replicas to support scallng needs. The read replicas must lag no more than 1 second behind the primary DB instance. The database routinely runs scheduled stored procedures. As traffic on the website increases, the replicas experince addtional lag during periods of peak load. A solutions architect must reduce the replication lag as much as possible. The solutin architect must minimize changes to the application code and must minimize ongoing operational overhead. Which solution will meet these requirements?

Accepted Answer

Migrate the database to Amazon Aurora MySQL. Replace the read replicas with Aurora Replicas, and configure Aurora Auto Scaling. Replace the store procedures with Aurora MySQL native functions.

Answer

Deploy an Amazon ElasticCache for Redis cluster in front of the database. Modify the application to check the cache before the applicatin queries the database. Replace the stored procedures with AWS Lambda functions.

Answer

Migrate the database to a MySQL database that runs on Amazon EC2 instances. Choose large, compute optimized EC2 instances for all replica nodes. Maintain the stored procedures on the EC2 instances.

Answer

Migrate the database to Amazon DynamicDB provision a large number of read capacity units(RCUs) to support the required throught, and configure on-demand capacity scaling. Replace the store procedures with DynamoDB streams

Question 38

A company runs an internal browser-based application The application runs on Amazon EC2 instances behind an Application Load Balancer. The instances run in an Amazon EC2 Auto Scaling group across multiple Availability Zones. The Auto Scaling group scales up to 20 instances during work hours but scales down to 2 instances overnight Staff are complaining that the application is very slow when the day begins although it runs well by mid-morning. How should the scaling be changed to address the staff complaints and keep costs to a minimum'?

Accepted Answer

Implement a target tracking action triggered at a lower CPU threshold, and decrease the cooldown period.

Answer

Implement a scheduled action that sets the desired capacity to 20 shortly before the office opens

Answer

Implement a step scaling action triggered at a lower CPU threshold, and decrease the cooldown period.

Answer

Implement a scheduled action that sets the minimum and maximum capacity to 20 shortly before the office opens

Question 39

A company is hosting a web application from an Amazon S3 bucket. The application uses Amazon Cognito as an identity provider lo authenticate users and return a JSON Web Token (JWT) that provides access to protected resources that am restored in another S3 bucket.Upon deployment of the application, users report errors and are unable to access the protected content. A solutions architect must resolve this issue by providing proper permissions so that users can access the protected content. Which solution meets these requirements?

Accepted Answer

Update the Amazon Cognito identity pool to assume the proper IAM role for access to the protected consent.

Answer

Update the S3 ACL to allow the application to access the protected content

Answer

Redeploy the application to Amazon 33 to prevent eventually consistent reads m the S3 bucket from affecting the ability of users to access the protected content.

Answer

Update the Amazon Cognito pool to use custom attribute mappings within tie Identity pool and grant users the proper permissions to access the protected content

Question 40

A company needs to migrate a legacy application from an on-premises data center to the AWS Cloud because of hardware capacity constraints. The application runs 24 hours a day. & days a week,. The application database storage continues to grow over time.What should a solution architect do to meet these requirements MOST cost-affectivity?

Accepted Answer

Migrate the application layer to Amazon EC2 Reserved instances Migrate the data storage layer to Amazon Aurora Reserved Instances.

Answer

Migrate the application layer to Amazon FC2 Spot Instances Migrate the data storage layer to Amazon S3.

Answer
