A solutions architect is using Amazon S3 to design the storage architecture of a new digital media application. The media files must be resilient to the loss of an Availability Zone. Some files are accessed frequently while other files are rarely accessed in an unpredictable pattern. The solutions architect must minimize the costs of storing and retrieving the media files. Which storage option meets these requirements? S3 Standard S3 Intelligent-Tiering S3 Standard-Infrequent Access (S3 Standard-IA) S3 One Zone-Infrequent Access (S3 One Zone-IA).
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 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. How to accomplish this? 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 1AM 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.

The company wants to be notified as soon as the Amazon EC2 instance usage for a given month exceeds a specific threshold for each account. What should a solutions architect do to meet this requirement MOST cost-effectively? Use Cost Explorer to create a daily report of costs by service. Filter the report by EC2 instances. Configure Cost Explorer to send an Amazon Simple Email Service (Amazon SES) notification when a threshold is exceeded. Use Cost Explorer to create a monthly report of costs by service. Filter the report by EC2 instances. Configure Cost Explorer to send an Amazon Simple Email Service (Amazon SES) notification when a threshold is exceeded. Use AWS Budgets to create a cost budget for each account. Set the period to monthly Set the scope to EC2 instances. Set an alert threshold for the budget. Configure an Amazon Simple Notification Service (Amazon SNS) topic to receive a notification when a threshold is exceeded. Use AWS Cost and Usage Reports to create a report with hourly granularity. Integrate the report data with Amazon Athena. Use Amazon EventBridge (Amazon CloudWatch Events) to schedule an Athena query. Configure an Amazon Simple Notifiication Service (Amazon SNS) topic lo receive a notification when a threshold is exceeded.
A company is hosting a website from an Amazon S3 bucket that is configured for public hosting. The company’s security team mandates the usage of secure connections for access to the website. However; HTTP-based URLS and HTTPS-based URLS must be functional. What should a solution architect recommend to meet these requirements? Create an S3 bucket policy to explicitly deny non-HTTPS traffic. Enable S3 Transfer Acceleration. Select the HTTPS Only bucket property. Place the website behind an Elastic Load Balancer that is configured to redirect HTTP traffic to HTTPS. Serve the website through an Amazon CloudFront distribution that is configured to redirect HTTP traffic to HTTPS.
A company hosts a serverless application on AWS. The application uses Amazon API Gateway. AWS Lambda, and an Amazon RDS for PostgreSQL database. The company notices an increase in application errors that result from database connection timeouts during times of peak traffic or unpredictable traffic. The company needs a solution that reduces the application failures with the least amount of change to the code. What should a solutions architect do to meet these requirements? Reduce the Lambda concurrency rate. Enable RDS Proxy on the RDS DB instance. Resize the RDS DB instance class to accept more connections. Migrate the database to Amazon DynamoDB with on-demand scaling.
A company is developing an Internal application that uses a PostgreSQL database. The company has decided to host the database on Amazon Aurora The application does not need to be highly available but data must be stored in multiple Availability Zones to maximize durability. Which database configuration meets these requirements MOST cost-effectively? An Aurora PostgreSQL DB cluster with a single DB Instance. An Aurora PostgreSQL DB cluster with a primary DB instance and a read replica. An Aurora PostgreSQL DB cluster with Multi-AZ deployment enabled. An Aurora PostgreSQL global database cluster.
A company stores confidential data in an Amazon Aurora PostgreSQL database in the ap-southeast-3 Region. The database is encrypted with an AWS Key Management Service (AWS KMS) customer managed key. The company was recently acquired and must securely share a backup of the database with the acquiring company's AWS account in ap-southeast-3. What should a solutions architect do to meet these requirements? Create a database snapshot. Copy the snapshot to a new unencrypted snapshot. Share the new snapshot with the acquiring company's AWS account. Create a database snapshot. Add the acquiring company's AWS account to the KMS key policy. Share the snapshot with the acquiring company's AWS account. Create a database snapshot that uses a different AWS managed KMS key. Add the acquiring company's AWS account to the KMS key alias. Share the snapshot with the acquiring company's AWS account. Create a database snapshot. Download the database snapshot. Upload the database snapshot to an Amazon S3 bucket. Update the S3 bucket policy to allow access from the acquiring company's AWS account.
A company is running a high performance computing (HPC) workload on AWS across many Linux based Amazon EC2 instances. The company needs a shared storage system that is capable of sub-millisecond latencies, hundreds of Gbps of throughput and millions of IOPS. Users will store millions of small files. Which solution meets these requirements? Create an Amazon Elastic File System (Amazon EFS) file system Mount me file system on each of the EC2 instances.

A company recently launched a new service that involves medical images. The company scans the images and sends them from its on-premises data center through an AWS Direct Connect connection to Amazon EC2 instances. After processing is complete, the images are stored in an Amazon S3 bucket. A company requirement states that the EC2 instances cannot be accessible through the internet. The EC2 instances run in a private subnet, which has a default route back to the on-premises data center for outbound internet access. Usage of the new service is increasing rapidly. A solutions architect must recommend a solution that meets the company's requirements and reduces the Direct Connect charges. Which solution accomplishes these goals MOST cost-effectively? Configure a VPC endpoint for Amazon S3. Add an entry to the private subnet's route table for the S3 endpoint. Configure a NAT gateway in a public subnet. Configure the private subnet's route table to use the NAT gateway. Configure Amazon S3 as a file system mount point on the EC2 instances. Access Amazon S3 through the mount. Move the EC2 instances into a public subnet. Configure the public subnet route table to point to an internet gateway.
A company is building an online multiplayer game. The game communicates by using UDP, and low latency between the client and the backend is important. The backend is hosted on Amazon EC2 instances that can be deployed to multiple AWS Regions to meet demand. The company needs the game to be highly available so that users around the world can access the game at all times. What should a solutions architect do to meet these requirements? Deploy Amazon CloudFront to support the global traffic. Configure CloudFront with an origin group to allow access to EC2 instances in multiple Regions. Deploy an Application Load Balancer in one Region to distribute traffic to EC2 instances in each Region that hosts the game's backend instances. Deploy Amazon CloudFront to support an origin access identity (OAI). Associate the OAI with EC2 instances in each Region to support global traffic. Deploy a Network Load Balancer in each Region to distribute the traffic. Use AWS Global Accelerator to route traffic to the correct Regional endpoint.
