A company wants to relocate its on-premises MySQL database to AWS The database accepts regular imports from a client-facing application when causes a high volume of write operations. The company is concerned that the amount of traffic might be causing performance issues within the application.
How should a solutions architect design the architecture on AWS?
A. Provision an Amazon RDS lor 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 tor MySQL 06 instance with General Purpose SSD storage Place an Amazon ElastiCache duster 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 tor performance-related issues Change the instance class it necessary
D. Provision an Amazon Elastic File System (Amazon EFS) He system in General Purpose performance mode Monitor Amazon CloudWatch tor IOPS bottlenecks Change to Provisioned Throughput performance mode if necessary.
A company is planning to host its compute-intensive applications on Amazon EC2 instances. The majority of the network traffic will be between these applications The company needs a solution that minimizes latency and maximizes network throughput The underlying hardware for the EC2 instances must not be shared with any other company
Which solution will meet these requirements?
A. Launch EC2 instances as Dedicated Hosts in a cluster placement group
B. Launch EC2 instances as Dedicated Hosts in a partition placement group
C. Launch EC2 instances as Dedicated Instances in a cluster placement group
D. Launch EC2 instances as Dedicated Instances in a partition placement group
A company uses GPS trackers to document the migration patterns of thousands of sea turtles The trackers check every 5 minutes to see if a turtle has moved more than 100 yards (91 4 meters) If a turtle has moved its tracker sends the new coordinates to a web application running on three Amazon EC2 instances that are in multiple Availability Zones in one AWS Region Recently, the web application was overwhelmed while processing an unexpected volume of tracker data Data was lost with no way to replay the events A solutions architect must prevent this problem from happening again and needs a solution with the least operationa overhead
What should the solutions architect do to meet these requirements''
A. Create an Amazon S3 bucket to store the data Configure the application to scan for new data in the bucket for processing
B. Create an Amazon API Gateway endpomt to handle transmitted location coordinates Use an AWS Lambda function to process each item concurrently
C. Create an Amazon Simple Queue Service (Amazon SQS) queue to store the incoming data Configure the application to poll for new messages for processing
D. Create an Amazon DynamoDB table to store transmitted location coordinates Configure the application to query the table for new data for processing Use TTL to remove data that has been processed.
A company needs a backup strategy for its three-tier stateless web application The web application runs on Amazon EC2 instances in an Auto Scaling group with a dynamic scaling policy that is configured to respond to scaling events The
database tier runs on Amazon RDS for PostgreSQL The web application does not require temporary local storage on the EC2 instances The company's recovery point objective (RPO) is 2 hours.
The backup strategy must maximize scalability and optimize resource utilization for this environment.
Which solution will meet these requirements?
A. Take snapshots of Amazon Elastic Block Store (Amazon EBS) volumes of the EC2 instances and database every 2 hours to meet the RPO
B. Configure a snapshot lifecycle policy to take Amazon Elastic Block Store (Amazon EBS) snapshots Enable automated backups in Amazon RDS to meet the RPO
C. Retain the latest Amazon Machine Images (AMIs) of the web and application tiers Enable automated backups in Amazon RDS and use point-in-time recovery to meet the RPO
D. Take snapshots of Amazon Elastic Block Store (Amazon EBS) volumes of the EC2 instances every 2 hours Enable automated backups in Amazon RDS and use point-in-time recovery to meet the RPO
A solutions architect is designing a shared storage solution for a web application that is deployed across multiple Availability Zones. The web application runs on Amazon EC2 instances that are in an Auto Scaling group. The company plans to make frequent changes to the content. The solution must have strong consistency in returning the new content as soon as the changes occur.
Which solutions meet these requirements? (Select TWO.)
A. Use AWS Storage Gateway Volume Gateway Internet Small Computer Systems Interface (ISCSI) block storage that is mounted to the individual EC2 instances.
B. Create an Amazon Elastic File System (Amazon EFS) file system. Mount the EFS file system on the individual EC2 instances.
C. Create a shared Amazon Elastic Block Store (Amazon EBS) volume. Mount the EBS volume on the individual EC2 instances.
D. Use AWS DataSync to perform continuous synchronization of data between EC2 hosts in the Auto Scaling group.
E. Create an Amazon S3 bucket to store the web content. Set the metadata for the Cache- Control header to no-cache. Use Amazon CloudFront to deliver the content.
A company allows users to upload and store photos through its website The website has users from all around the world. All images that users upload are stored in a centralized Amazon S3 bucket The company wants to increase the speed in which its entire user base can upload photos through the website.

A company has a data ingestion workflow that consists the following:
An Amazon Simple Notification Service (Amazon SNS) topic for notifications about new data deliveries An AWS Lambda function to process the data and record metadata The company observes that the ingestion workflow fails occasionally
because of network connectivity issues.

Which combination of actions should a solutions architect take to ensure that the Lambda function ingests all data in the future? (Select TWO.)
A. Configure the Lambda function In multiple Availability Zones.
B. Create an Amazon Simple Queue Service (Amazon SQS) queue, and subscribe It to me SNS topic.
C. Increase the CPU and memory that are allocated to the Lambda function.
D. Increase provisioned throughput for the Lambda function.
E. Modify the Lambda function to read from an Amazon Simple Queue Service (Amazon SQS) queue
