An enterprise runs 103 line-of-business applications on virtual machines in an on-premises data center. Many of the applications are simple PHP. Java, or Ruby web applications, are no longer actively developed, and serve little traffic.
Which approach should be used to migrate these applications to AWS with the LOWEST infrastructure costs?
A. Deploy the applications lo single-instance AWS Elastic Beanstalk environments without a load balancer.
B. Use AWS SMS to create AMls for each virtual machine and run them in Amazon EC2.
C. Convert each application to a Docker image and deploy to a small Amazon ECS cluster behind an Application Load Balancer.
D. Use VM Import/Export to create AMls for each virtual machine and run them in single-instance AWS Elastic Beanstalk environments by configuring a custom image.
A solutions architect has deployed a web application that serves users across two AWS Regions under a custom domain. The application uses Amazon Route 53 latency-based routing The solutions architect has associated weighted record sets with a pair of web servers in separate Availability Zones for each Region. The solutions architect runs a disaster recovery scenario
When all the web servers in one Region are stopped Route 53 does not automatically redirect users to the other Region.
Which of the following are possible root causes of this issue? (Select TWO.)
A. The weight for the Region where the web servers were stopped is higher than the weight for the other Region
B. One of the web servers in the secondary Region did not pass its HTTP health check
C. Latency resource record sets cannot be used in combination with weighted resource record sets
D. The setting to evaluate target health is not turned on for the latency alias resource record set that is associated with the domain in the Region where the web servers were stopped
E. An HTTP health check has not been set up for one or more of the weighted resource record sets associated with the stopped web servers
A company operates quick-service restaurants. The restaurants follow a predictable model with high sales traffic for -4 hours daily Sates traffic is lower outside of those peak hours.
The point of sale and management platform is deployed in the AWS Cloud and has a backend that is based or Amazon DynamoDB The database table uses provisioned throughput mode with 100.000 RCUs and 80.000 WCUs to match Known peak resource consumption.
The company wants to reduce its DynamoDB cost and minimize the operational overhead for the IT staff.
Which solution meets these requirements MOST cost-effectively?
A. Reduce the provisioned RCUs and WCUs
B. Change the DynamoDB table to use on-demand capacity
C. Enable Dynamo DB auto seating for the table.
D. Purchase 1-year reserved capacity that is sufficient to cover the peak load for 4 hours each day.
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.)
A. Deploy the application to Amazon EC2 On-Demand Instances With load balancing across multiple Availability Zones. Use scheduled Amazon EC2 Auto Scaling to add capacity before the high volume of submissions on Fridays.
B. Deploy the application in a container using Amazon Elastic Container Service (Amazon ECS) with load balancing across multiple Availability Zones. Use scheduled Service Auto Scaling to add capacity before the high volume of submissions on Fridays.
C. Deploy the application front end to an Amazon S3 bucket served by Amazon CloudFront. Deploy the application backend using Amazon API Gateway with an AWS Lambda proxy integration.
D. Store the timesheet submission data in Amazon Redshift. Use Amazon OuickSight to generate the reports using Amazon Redshift as the data source.
E. 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.
A company is migrating an on-premises content management system (CMS) to AWS Fargate. The company uses the CMS for blog posts that include text, images, and videos. The company has observed that traffic to blog posts drops by more than 80% after the posts are more than 30 days old.
The CMS runs on multiple VMs and stores application state on disk This application state is shared across all instances across multiple Availability Zones Images and other media are stored on a separate NFS file share. The company needs to reduce the costs of the existing solution while minimizing the impact on performance.
Which combination of steps will meet these requirements MOST cost-effectively? (Select TWO.)
A. Store media in an Amazon S3 Standard bucket Create an S3 Lifecycle configuration that transitions objects that are older than 30 days to the S3 Standard-Infrequent Access (S3 Standard-IA) storage class.
B. Store media on an Amazon Elastic File System (Amazon EFS) volume Attach the EFS volume to all Fargate instances.
C. Store application state on an Amazon Elastic File System (Amazon EFS) volume Attach the EFS volume to all Fargate instances.
D. Store application state on an Amazon Elastic Block Store (Amazon EBS) volume Attach the EBS volume to all Fargate instances.
E. Store media in an Amazon S3 Standard bucket Create an S3 Lifecycle configuration that transitions objects that are older than 30 days to the S3 Glacier storage class
A solutions architect needs to provide AWS Cost and Usage Report data from a company's AWS Organizations management account The company already has an Amazon S3 bucket to store the reports The reports must be automatically ingested into a database that can be visualized with other toots.
Which combination of steps should the solutions architect take to meet these requirements? (Select THREE )
A. Create an Amazon EventBridge (Amazon CloudWatch Events) rule that a new object creation in the S3 bucket will trigger
B. Create an AWS Cost and Usage Report configuration to deliver the data into the S3 bucket
C. Configure an AWS Glue crawler that a new object creation in the S3 bucket will trigger.
D. Create an AWS Lambda function that a new object creation in the S3 bucket will trigger
E. Create an AWS Glue crawler that me AWS Lambda function will trigger to crawl objects in me S3 bucket
F. Create an AWS Glue crawler that the Amazon EventBridge (Amazon CloudWatCh Events) rule will trigger to crawl objects m the S3 bucket
A company wants to send data from its on-premises systems to Amazon S3 buckets. The company
created the S3 buckets in three different accounts. The company must send the data privately without the
data traveling across the internet.
The company has no existing dedicated connectivity to AWS.
