An environment has an Auto Scaling group across two Availability Zones to as AZ-a and AZ-b has four instances, and AZ-b has three EC2 instances. The Auto Scaling group uses a default termination policies. None of the instances are protected from a scale-in event. How will Auto Scaling processed if there is a scale-in event?
A. Auto Scaling selects an instance to terminate randomly.A company is running a multi-tier ecommerce web application in the AWS Cloud The web application is running on Amazon EC2 instances. The database tier Is on a provisioned Amazon Aurora MySQL DB cluster with a writer and a reader in a Multi-AZ environment. The new requirement for the database tier is to serve the application to achieve continuous write availability through an Instance failover.
What should a solutions architect do to meet this new requirement?
A. Add a new AWS Region to the DB cluster for multiple writesA company has two AWS accounts: Production and Development There are code changes ready in the Development account to push to the Production account In the alpha phase, only two senior developers on the development team need
access to the Production account in the beta phase, more developers might need access to perform testing as well.
What should a solutions architect recommend?
A. Create two policy documents using the AWS Management Console in each account Assign the policy to developers who need accessA company's web application consists o( an Amazon API Gateway API in front of an AWS Lambda function and an Amazon DynamoDB database. The Lambda function handles the business logic, and the DynamoDB table hosts the data. The application uses Amazon Cognito user pools to identify the individual users of the application. A solutions architect needs to update the application so that only users who have a subscription can access premium content.
A. Enable API caching and throttling on the API Gateway APIAn entertainment company is using Amazon DynamoDB to store media metadata. The application Is read intensive and experience delays The company does not have staff to handle additional operational overhead and needs to Improve the performance efficiency of DynamoDB without reconfiguring the application
What should a solutions architect recommend to meet this requirement?
A. Use Amazon ElastiCache for RedisA research company runs experiments that are powered by a simulation application and a visualization application. The simulation application runs on Linux and outputs intermediate data to an NFS share every 5 minutes. The visualization application is a Windows desktop application that displays the simulation output and requires an SMB file system.
The company maintains two synchronized tile systems. This strategy is causing data duplication and inefficient resource usage. The company needs to migrate the applications to AWS without making code changes to either application. Which solution will meet these requirements?
A. Migrate both applications to AWS Lambda Create an Amazon S3 bucket to exchange data between the applications.A company has a web application that is based ornavaan^PH^Tnecompan^lanstomove the application from on premises to AWS The company needs the ability to test new site features frequently The company also needs a highly available and managed solution that requires minimum operational overhead.
Which solution will meet these requirements?
A. Create an Amazon S3 bucket Enable static web hosting on the S3 bucket Upload the static content to the S3 bucket Use AWS Lambda to process all dynamic contentAn ecommerce company has an order-processing application that uses Amazon API Gateway and an AWS Lambda function. The application stores data in an Amazon Aurora PostgreSQL database. During a recent sales event, a sudden surge in customer orders occurred. Some customers experienced timeouts and the application did not process the orders of those customers A solutions architect determined that the CPU utilization and memory utilization were high on the database because of a large number of open connections The solutions architect needs to prevent the timeout errors while making the least possible changes to the application.
Which solution will meet these requirements?
A. Configure provisioned concurrency for the Lambda function Modify the database to be a global database in multiple AWS RegionsA company wants a storage option that enables its data science team to analyze its data on premises and in the AWS Cloud The team needs to be able to run statistical analyses by using the data on premises and by using a fleet of Amazon EC2 instances across multiple Availability Zones. What should a solutions architect do to meet these requirements?
A. Use an AWS Storage Gateway tape gateway to copy the on-premises files into Amazon S3.A company is developing a video conversion application hosted on AWS. The application will be available in two tiers: a free tier and a paid tier. Users in the paid tier will have their videos converted first and then the tree tier users will have their videos converted.
Which solution meets these requirements and is MOST cost-effective?
A. One FIFO queue for the paid tier and one standard queue for the free tierNowadays, the certification exams become more and more important and required by more and more enterprises when applying for a job.
