Free AWS Certified Solutions Architect – Associate SAA-C03 Exam Practice Test

A company is hosting a three-tier ecommerce application in the AWS Cloud. The company hosts the website on Amazon S3 and integrates the website with an API that handles sales requests. The company hosts the API on three Amazon EC2 instances behind an Application Load Balancer (ALB). The API consists of static and dynamic front-end content along with backend workers that process sales requests asynchronously.The company is expecting a significant and sudden increase in the number of sales requests during events for the launch of new productsWhat should a solutions architect recommend to ensure that all the requests are processed successfully?

• Add an Amazon CloudFront distribution for the dynamic content. Increase the number of EC2 instances to handle the increase in traffic.
• Add an Amazon CloudFront distribution for the static content. Place the EC2 instances in an Auto Scaling group to launch new instances based on network traffic.
• Add an Amazon CloudFront distribution for the dynamic content. Add an Amazon ElastiCache instance in front of the ALB to reduce traffic for the API to handle.
• Add an Amazon CloudFront distribution for the static content. Add an Amazon Simple Queue Service (Amazon SOS) queue to receive requests from the website for later processing by the EC2 instances.

A solutions architect must migrate a Windows Internet Information Services (IIS) web application to AWS The application currently relies on a file share hosted in the user's on-premises network-attached storage (NAS) The solutions architect has proposed migrating the MS web servers to Amazon EC2 instances in multiple Availability Zones that are connected to the storage solution, and configuring an Elastic Load Balancer attached to the instancesWhich replacement to the on-premises file share is MOST resilient and durable?

• Migrate the file share to Amazon RDS
• Migrate the file share to AWS Storage Gateway
• Migrate the file share to Amazon FSx for Windows File Server
• Migrate the file share to Amazon Elastic File System (Amazon EFS)

A company has a web application with sporadic usage patterns There is heavy usage at the beginning of each month moderate usage at the start of each week and unpredictable usage during the week The application consists of a web server and a MySQL database server running inside the data center The company would like to move the application to the AWS Cloud and needs to select a cost-effective database platform that will not require database modificationsWhich solution will meet these requirements?

• Amazon DynamoDB
• Amazon RDS for MySQL

A company wants to measure the effectiveness of its recent marketing campaigns. The company performs batch processing on csv files of sales data and stores the results i an Amazon S3 bucket once every hour. The S3 bi petabytes of objects. The company runs one-time queries in Amazon Athena to determine which products are most popular on a particular date for a particular region Queries sometimes fail or take longer than expected to finish.Which actions should a solutions architect take to improve the query performance and reliability? (Select TWO.)

• Reduce the S3 object sizes to less than 126 MB
• Partition the data by date and region n Amazon S3
• Store the files as large, single objects in Amazon S3.
• Use Amazon Kinosis Data Analytics to run the Queries as pan of the batch processing operation
• Use an AWS duo extract, transform, and load (ETL) process to convert the csv files into Apache Parquet format.

A company's facility has badge readers at every entrance throughout the building. When badges are scanned, the readers send a message over HTTPS to indicate who attempted to access that particular entrance.A solutions architect must design a system to process these messages from the sensors. The solution must be highly available, and the results must be made available for the company's security team to analyze.Which system architecture should the solutions architect recommend?

• Launch an Amazon EC2 instance to serve as the HTTPS endpoint and to process the messages Configure the EC2 instance to save the results to an Amazon S3 bucket.
• Create an HTTPS endpoint in Amazon API Gateway. Configure the API Gateway endpoint to invoke an AWS Lambda function to process the messages and save the results to an Amazon DynamoDB table.
• Use Amazon Route 53 to direct incoming sensor messages to an AWS Lambda function. Configure the Lambda function to process the messages and save the results to an Amazon DynamoDB table.
• Create a gateway VPC endpoint for Amazon S3. Configure a Site-to-Site VPN connection from the facility network to the VPC so that sensor data can be written directly to an S3 bucket by way of the VPC endpoint.

A company has a multi-tier application deployed on several Amazon EC2 instances in an Auto Scaling group. An Amazon RDS for Oracle instance is the application's data layer that uses Oracle-specificPL/SQL functions. Traffic to the application has been steadily increasing. This is causing the EC2 instances to become overloaded and the RDS instance to run out of storage. The Auto Scaling group does not have any scaling metrics and defines the minimum healthy instance count only. The company predicts that traffic will continue to increase at a steady but unpredictable rate before levelling off.What should a solutions architect do to ensure the system can automatically scale for the increased traffic? (Select TWO.)

• Configure storage Auto Scaling on the RDS for Oracle Instance.
• Migrate the database to Amazon Aurora to use Auto Scaling storage.
• Configure an alarm on the RDS for Oracle Instance for low free storage space
• Configure the Auto Scaling group to use the average CPU as the scaling metric
• Configure the Auto Scaling group to use the average free memory as the seeing metric

A company is storing backup files by using Amazon S3 Standard storage. The files are accessed frequently for 1 month. However, the files are not accessed after 1 month. The company must keep the files indefinitely.Which storage solution will meet these requirements MOST cost-effectively?

• Configure S3 Intelligent-Tiering to automatically migrate objects.
• Create an S3 Lifecycle configuration to transition objects from S3 Standard to S3 Glacier Deep Archive after 1 month.
• Create an S3 Lifecycle configuration to transition objects from S3 Standard to S3 Standard-Infrequent Access (S3 Standard-IA) after 1 month.
• Create an S3 Lifecycle configuration to transition objects from S3 Standard to S3 One Zone-Infrequent Access (S3 One Zone-IA) after 1 month.

A company is implementing a shared storage solution for a media application that is hosted m the AWS Cloud The company needs the ability to use SMB clients to access data The solution must he fully managed.Which AWS solution meets these requirements?

• Create an AWS Storage Gateway volume gateway. Create a file share that uses the required client protocol Connect the application server to the file share.
• Create an AWS Storage Gateway tape gateway Configure (apes to use Amazon S3 Connect the application server lo the tape gateway
• Create an Amazon EC2 Windows instance Install and configure a Windows file share role on the instance. Connect the application server to the file share.
• Create an Amazon FSx for Windows File Server tile system Attach the fie system to the origin server. Connect the application server to the file system

A company's web application consists of an Amazon API Gateway API in front of an AWS Lambda function and an Amazon DynamoDB database. The Lambda functionhandles 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.

• Enable API caching and throttling on the API Gateway API
• Set up AWS WAF on the API Gateway API Create a rule to filter users who have a subscription
• Apply fine-grained IAM permissions to the premium content in the DynamoDB table
• Implement API usage plans and API keys to limit the access of users who do not have a subscription.

A company hosts an application on multiple Amazon EC2 instances The application processes messages from an Amazon SQS queue writes to an Amazon RDS table and deletes the message from the queue Occasional duplicate records are found in the RDS table.
