Question #527 / 1019

A company operates a global e-commerce platform using a single AWS Region. The architecture includes web servers and application servers on Amazon EC2 instances within Auto Scaling groups behind Elastic Load Balancers. The platform uses an Amazon Aurora global database cluster spanning multiple Availability Zones. The company wants to ensure maximum fault tolerance and minimal downtime during regional outages.

Which solution provides the MOST fault tolerance?

A

Extend the Auto Scaling groups for the web and application tiers to deploy instances in a second Region. Use an Aurora global database in both Regions. Configure Amazon Route 53 with health checks and a failover routing policy to direct traffic to the second Region during outages.

B

Deploy the web and application tiers to a second Region. Create a cross-Region Aurora Replica in the second Region. Use Amazon Route 53 health checks with a failover routing policy to the second Region. Manually promote the secondary database to primary during failover.

C

Deploy the web and application tiers to a second Region. Provision a new Aurora PostgreSQL database in the second Region. Use AWS Database Migration Service (AWS DMS) for continuous replication between the primary and secondary Regions. Configure Route 53 with a failover routing policy.

D

Deploy the web and application tiers to a second Region. Use an Aurora global database spanning both Regions. Configure Amazon Route 53 with health checks and a failover routing policy to the second Region. Promote the secondary database to primary during regional outages.

Question #350 / 1019

Which combination of steps will meet these requirements? (Choose two.)

A

Convert the DB instance from Single-AZ to Multi-AZ deployment.

B

Sample Questions

Question #251 / 529

A company provides a REST API for six US-based partners to retrieve inventory data once daily using an Amazon API Gateway Regional endpoint. After deployment, the company observes 2,000 requests per second originating from 800 different IP addresses globally, suspected to be a botnet. The company needs to secure the API while minimizing costs.

Which approach should the company take to secure its API?

A

Create an Amazon CloudFront distribution with the API as the origin. Configure AWS WAF with a rule to block clients exceeding two requests per day. Associate the WAF web ACL with CloudFront. Use an origin access identity (OAI) to restrict API access to CloudFront. Require an API key for the GET method in API Gateway.

B

Create an Amazon CloudFront distribution with the API as the origin. Configure AWS WAF with a rule to allow only the partners' IP addresses. Associate the WAF web ACL with CloudFront. Add a custom header with an API key to the distribution. Require the API key for the GET method in API Gateway.

C

Create an AWS WAF web ACL to block all IPs except the partners'. Associate it with the API. Create a resource policy to throttle requests and attach it to the API. Require an API key for the GET method.

D

Create an AWS WAF web ACL to allow only the partners' IP addresses. Associate it with the API. Create a usage plan with a request limit and link it to the API. Generate an API key and add it to the usage plan.

Question #288 / 529

A company is developing a global video streaming platform that allows users to upload and transcode videos in real-time. At peak, the service must handle 15,000 concurrent uploads worldwide. After upload, videos must be processed to generate adaptive bitrate streams, which are then distributed via a content delivery network (CDN).

Which architecture should a solutions architect recommend?

A

Store uploaded videos in Amazon Elastic File System (Amazon EFS). Use Amazon CloudWatch Logs to track upload events. Deploy Amazon EC2 instances that monitor CloudWatch Logs to trigger video processing. Store transcoded videos in a separate EFS directory. Configure Amazon CloudFront with an EC2 instance as the origin.

B

Store uploaded videos in an Amazon S3 bucket and configure S3 event notifications to publish to Amazon Simple Notification Service (Amazon SNS). Use EC2 instances behind an Application Load Balancer (ALB) to consume SNS messages for processing. Store transcoded videos in Amazon EFS. Scale EC2 instances using CloudWatch metrics for SNS message volume. Set CloudFront's origin to the ALB.

C

Store uploaded videos in an Amazon S3 bucket and configure S3 event notifications to send messages to an Amazon Simple Queue Service (SQS) queue. Deploy auto-scaling EC2 instances to process videos by pulling messages from the SQS queue. Store transcoded videos in another S3 bucket. Scale EC2 instances based on SQS queue depth using CloudWatch. Configure CloudFront with the processed S3 bucket as the origin.

D

Store uploaded videos on a shared Amazon Elastic Block Store (EBS) volume attached to EC2 Spot instances. Track processing status in an Amazon DynamoDB table. Use Amazon EventBridge rules to scale EC2 instances. Configure CloudFront with an Elastic Load Balancer (ELB) as the origin.

Question #393 / 557

A company operates a production application on Amazon ECS using AWS Fargate. To optimize costs, the company wants to integrate FARGATE_SPOT capacity providers into their existing Fargate setup while ensuring high availability. A developer must configure the ECS cluster's capacity provider strategy to minimize downtime during the transition. Which solution meets these requirements?

A

Use the PutClusterCapacityProviders API operation to update the ECS cluster with the FARGATE and FARGATESPOT capacity provider strategies. Set FARGATE as the default provider with a base value and FARGATESPOT as the secondary provider for cost optimization.

B

Use the CreateCapacityProvider API operation to associate the ECS cluster with the FARGATE and FARGATESPOT capacity provider strategies. Configure FARGATE as the primary provider with a base value and FARGATESPOT as the secondary provider.

C

Use the PutClusterCapacityProviders API operation to update the ECS cluster with the FARGATESPOT and FARGATE capacity provider strategies. Set FARGATESPOT as the default provider for maximum cost savings and FARGATE as the failover provider.

D

Use the CreateCapacityProvider API operation to associate the ECS cluster with the FARGATESPOT and FARGATE capacity provider strategies. Configure FARGATESPOT as the primary provider and FARGATE as the secondary provider.
