A solutions architect needs to advise a company on how to migrate its on-premises data processing application to the AWS Cloud. Currently, users upload input files through a web portal. The web server then stores the uploaded files on NAS and messages the processing server over a message queue. Each media file can take up to 1 hour to process. The company has determined that the number of media files awaiting processing is significantly higher during business hours, with the number of files rapidly declining after business hours. What is the MOST cost-effective migration recommendation?
A. Create a queue using Amazon SQS. Configure the existing web server to publish to the new queue. When there are messages in the queue, invoke an AWS Lambda function to pull requests from the queue and process the files. Store the processed files in an Amazon S3 bucket. B. Create a queue using Amazon MQ. Configure the existing web server to publish to the new queue. When there are messages in the queue, create a new Amazon EC2 instance to pull requests from the queue and process the files. Store the processed files in Amazon EFS. Shut down the EC2 instance after the task is complete. C. Create a queue using Amazon MQ. Configure the existing web server to publish to the new queue. When there are messages in the queue, invoke an AWS Lambda function to pull requests from the queue and process the files. Store the processed files in Amazon EFS. D. Create a queue using Amazon SQS. Configure the existing web server to publish to the new queue. Use Amazon EC2 instances in an EC2 Auto Seating group to pull requests from the queue and process the files.

A utility company wants to collect usage data every 5 minutes from its smart meters to facilitate time-of-use metering. When a meter sends data to AWS, the data is sent to Amazon API Gateway, processed by an AWS Lambda function and stored in an Amazon DynamoDB table. During the pilot phase, the Lambda functions took from 3 to 5 seconds to complete. As more smart meters are deployed, the Engineers notice the Lambda functions are taking from 1 to 2 minutes to complete. The functions are also increasing in duration as new types of metrics are collected from the devices. There are many ProvisionedThroughputExceededException errors while performing PUT operations on DynamoDB, and there are also many TooManyRequestsException errors from Lambda. Which combination of changes will resolve these issues? (Choose two.)
A. Increase the write capacity units to the DynamoDB table. B. Increase the memory available to the Lambda functions. C. Increase the payload size from the smart meters to send more data. D. Stream the data into an Amazon Kinesis data stream from API Gateway and process the data in batches. E. Collect data in an Amazon SQS FIFO queue, which triggers a Lambda function to process each message.

An ecommerce website running on AWS uses an Amazon RDS for MySQL DB instance with General Purpose SSD storage. The developers chose an appropriate instance type based on demand, and configured 100 GB of storage with a sufficient amount of free space. The website was running smoothly for a few weeks until a marketing campaign launched. On the second day of the campaign, users reported long wait times and time outs. Amazon CloudWatch metrics indicated that both reads and writes to the DB instance were experiencing long response times. The CloudWatch metrics show 40% to 50% CPU and memory utilization, and sufficient free storage space is still available. The application server logs show no evidence of database connectivity issues. What could be the root cause of the issue with the marketing campaign?
A. It exhausted the I/O credit balance due to provisioning low disk storage during the setup phase. B. It caused the data in the tables to change frequently, requiring indexes to be rebuilt to optimize queries. C. It exhausted the maximum number of allowed connections to the database instance. D. It exhausted the network bandwidth available to the RDS for MySQL DB instances.

A solutions architect has been assigned to migrate a 50 TB Oracle data warehouse that contains sales data from on-premises to Amazon Redshift. Major updates to the sales data occur on the final calendar day of the month. For the remainder of the month, the data warehouse only receives minor daily updates and is primarily used for reading and reporting. Because of this, the migration process must start on the first day of the month and must be complete before the next set of updates occur. This provides approximately 30 days to complete the migration and ensure that the minor daily changes have been synchronized with the Amazon Redshift data warehouse. Because the migration cannot impact normal business network operations, the bandwidth allocated to the migration for moving data over the internet is 50 Mbps. The company wants to keep data migration costs low. Which steps will allow the solutions architect to perform the migration within the specified timeline?
A. Install Oracle database software on an Amazon EC2 instance. Configure VPN connectivity between AWS and the company’s data center. Configure the Oracle database running on Amazon EC2 to join the Oracle Real Application Clusters (RAC). When the Oracle database on Amazon EC2 finishes synchronizing, create an AWS DMS ongoing replication task to migrate the data from the Oracle database on Amazon EC2 to Amazon Redshift. Verify the data migration is complete and perform the cut over to Amazon Redshift. B. Create an AWS Snowball import job. Export a backup of the Oracle data warehouse. Copy the exported data to the Snowball device. Return the Snowball device to AWS. Create an Amazon RDS for Oracle database and restore the backup file to that RDS instance. Create an AWS DMS task to migrate the data from the RDS for Oracle database to Amazon Redshift. Copy daily incremental backups from Oracle in the data center to the RDS for Oracle database over the internet. Verify the data migration is complete and perform the cut over to Amazon Redshift. C. Install Oracle database software on an Amazon EC2 instance. To minimize the migration time, configure VPN connectivity between AWS and the company’s data center by provisioning a 1 Gbps AWS Direct Connect connection. Configure the Oracle database running on Amazon EC2 to be a read replica of the data center Oracle database. Start the synchronization process between the company’s on-premises data center and the Oracle database on Amazon EC2. When the Oracle database on Amazon EC2 is synchronized with the on-premises database, create an AWS DMS ongoing replication task to migrate the data from the Oracle database read replica that is running on Amazon EC2 to Amazon Redshift. Verify the data migration is complete and perform the cut over to Amazon Redshift. D. Create an AWS Snowball import job. Configure a server in the company’s data center with an extraction agent. Use AWS SCT to manage the extraction agent and convert the Oracle schema to an Amazon Redshift schema. Create a new project in AWS SCT using the registered data extraction agent. Create a local task and an AWS DMS task in AWS SCT with replication of ongoing changes. Copy data to the Snowball device and return the Snowball device to AWS. Allow AWS DMS to copy data from Amazon S3 to Amazon Redshift. Verify that the data migration is complete and perform the cut over to Amazon Redshift.
