A company is running an application in the AWS Cloud. The application uses AWS Lambda functions and Amazon Elastic Container Service (Amazon ECS) containers that run with AWS Fargate technology as its primary compute. The load on the application is irregular. The application experiences long periods of no usage, followed by sudden and significant increases and decreases in traffic. The application is write-heavy and stores data in an Amazon Aurora MySQL database. The database runs on an Amazon RDS memory optimized D8 instance that is not able to handle the load.
What is the MOST cost-effective way for the company to handle the sudden and significant changes in traffic?

1. A. Add additional read replicas to the databas
2. B. Purchase Instance Savings Plans and RDS Reserved Instances.
3. C. Migrate the database to an Aurora multi-master DB cluste
4. D. Purchase Instance Savings Plans.
5. E. Migrate the database to an Aurora global database Purchase Compute Savings Plans and RDS Reserved Instances
6. F. Migrate the database to Aurora Serverless v1. Purchase Compute Savings Plans

A developer reports receiving an Error 403: Access Denied message when they try to download an object from an Amazon S3 bucket. The S3 bucket is accessed using an S3 endpoint inside a VPC. and is encrypted with an AWS KMS key. A solutions architect has verified that (he developer is assuming the correct IAM role in the account that allows the object to be downloaded. The S3 bucket policy and the NACL are also valid.
Which additional step should the solutions architect take to troubleshoot this issue?

1. A. Ensure that blocking all public access has not been enabled in the S3 bucket.
2. B. Verify that the IAM rote has permission to decrypt the referenced KMS key.
3. C. Verify that the IAM role has the correct trust relationship configured.
4. D. Check that local firewall rules are not preventing access to the S3 endpoint.

Correct Answer: B

A company is planning to migrate an Amazon RDS for Oracle database to an RDS for PostgreSQL DB instance in another AWS account A solutions architect needs to design a migration strategy that will require no downtime and that will minimize the amount of time necessary to complete the migration The migration strategy must replicate all existing data and any new data that is created during the migration The target database must be identical to the source database at completion of the migration process
All applications currently use an Amazon Route 53 CNAME record as their endpoint for communication with the RDS for Oracle DB instance The RDS for Oracle DB instance is in a private subnet
Which combination of steps should the solutions architect take to meet these requirements? (Select THREE )

1. A. Create a new RDS for PostgreSQL DB instance in the target account Use the AWS Schema Conversion Tool (AWS SCT) to migrate the database schema from the source database to the target database.
2. B. Use the AWS Schema Conversion Tool (AWS SCT) to create a new RDS for PostgreSQL DB instance in the target account with the schema and initial data from the source database
3. C. Configure VPC peering between the VPCs in the two AWS accounts to provide connectivity to both DB instances from the target accoun
4. D. Configure the security groups that are attached to each DB instance to allow traffic on the database port from the VPC in the target account
5. E. Temporarily allow the source DB instance to be publicly accessible to provide connectivity from the VPC in the target account Configure the security groups that are attached to each DB instance to allow traffic on the database port from the VPC in the target account.
6. F. Use AWS Database Migration Service (AWS DMS) in the target account to perform a full load plus change data capture (CDC) migration from the source database to the target database When the migration is complete, change the CNAME record to point to the target DB instance endpoint
7. G. Use AWS Database Migration Service (AWS DMS) in the target account to perform a change data capture (CDC) migration from the source database to the target database When the migration is complete change the CNAME record to point to the target DB instance endpoint

A company has implemented an ordering system using an event-dnven architecture. Dunng initial testing, the system stopped processing orders Further tog analysis revealed that one order message in an Amazon Simple Queue Service (Amazon SOS) standard queue was causing an error on the backend and blocking all subsequent order messages The visibility timeout of the queue is set to 30 seconds, and the backend processing timeout is set to 10 seconds. A solutions architect needs to analyze faulty order messages and ensure that the system continues to process subsequent messages
Which step should the solutions architect take to meet these requirements?

1. A. Increase the backend processing timeout to 30 seconds to match the visibility timeout
2. B. Reduce the visibility timeout of the queue to automatically remove the faulty message
3. C. Configure a new SOS FIFO queue as a dead-letter queue to isolate the faulty messages
4. D. Configure a new SOS standard queue as a dead-letter queue to isolate the faulty messages.

Correct Answer: D

A solutions architect is designing an application to accept timesheet entries from employees on their mobile devices. Timesheets will be submitted weekly, with most of the submissions occurring on Friday. The data must be stored in a format that allows payroll administrators to run monthly reports. The infrastructure must be highly available and scale to match the rate of incoming data and reporting requests.
Which combination of steps meets these requirements while minimizing operational overhead? (Select TWO.)

1. A. Deploy the application to Amazon EC2 On-Demand Instances With load balancing across multiple Availability Zone
2. B. Use scheduled Amazon EC2 Auto Scaling to add capacity before the high volume of submissions on Fridays.
3. C. Deploy the application in a container using Amazon Elastic Container Service (Amazon ECS) with load balancing across multiple Availability Zone
4. D. Use scheduled Service Auto Scaling to add capacity before the high volume of submissions on Fridays.
5. E. Deploy the application front end to an Amazon S3 bucket served by Amazon CloudFron
6. F. Deploy the application backend using Amazon API Gateway with an AWS Lambda proxy integration.
7. G. Store the timesheet submission data in Amazon Redshif
8. H. Use Amazon OuickSight to generate the reports using Amazon Redshift as the data source.
9. I. Store the timesheet submission data in Amazon S3. Use Amazon Athena and Amazon OuickSight to generate the reports using Amazon S3 as the data source.
