A company owns an asynchronous API that is used to ingest user requests and, based on the request type, dispatch requests to the appropriate microservice for processing. The company is using Amazon API Gateway to deploy the API front end, and an AWS Lambda function that invokes Amazon DynamoDB to store user requests before dispatching them to the processing microservices.
The company provisioned as much DynamoDB throughput as its budget allows, but the company is still experiencing availability issues and is losing user requests.
What should a solutions architect do to address this issue without impacting existing users?

1. A. Add throttling on the API Gateway with server-side throttling limits.
2. B. Use DynamoDB Accelerator (DAX) and Lambda to buffer writes to DynamoDB.
3. C. Create a secondary index in DynamoDB for the table with the user requests.
4. D. Use the Amazon Simple Queue Service (Amazon SQS) queue and Lambda to buffer writes to DynamoDB.

Correct Answer: D
By using an SQS queue and Lambda, the solutions architect can decouple the API front end from the processing microservices and improve the overall scalability and availability of the system. The SQS queue acts as a buffer, allowing the API front end to continue accepting user requests even if the processing microservices are experiencing high workloads or are temporarily unavailable. The Lambda function can then retrieve requests from the SQS queue and write them to DynamoDB, ensuring that all user requests are stored and processed. This approach allows the company to scale the processing microservices independently from the API front end, ensuring that the API remains available to users even during periods of high demand.

A company recently announced the deployment of its retail website to a global audience. The website runs on multiple Amazon EC2 instances behind an Elastic Load Balancer. The instances run in an Auto Scaling group across multiple Availability Zones.
The company wants to provide its customers with different versions of content based on the devices that the customers use to access the website.
Which combination of actions should a solutions architect take to meet these requirements? (Choose two.)

1. A. Configure Amazon CloudFront to cache multiple versions of the content.
2. B. Configure a host header in a Network Load Balancer to forward traffic to different instances.
3. C. Configure a Lambda@Edge function to send specific objects to users based on the User-Agent header.
4. D. Configure AWS Global Accelerato
5. E. Forward requests to a Network Load Balancer (NLB). Configure the NLB to set up host-based routing to different EC2 instances.
6. F. Configure AWS Global Accelerato
7. G. Forward requests to a Network Load Balancer (NLB). Configure the NLB to set up path-based routing to different EC2 instances.

Correct Answer: AC
For C: IMPROVED USER EXPERIENCE Lambda@Edge can help improve your users' experience with your websites and web applications across the world, by letting you personalize content for them without sacrificing performance. Real-time Image Transformation You can customize your users' experience by transforming images on the fly based on the user characteristics. For example, you can resize images based on the viewer's device type—mobile, desktop, or tablet. You can also cache the transformed images at CloudFront Edge locations to further improve performance when delivering images. https://aws.amazon.com/lambda/edge/

A company wants to restrict access to the content of one of its man web applications and to protect the content by using authorization techniques available on AWS. The company wants to implement a serverless architecture end an authentication solution for fewer tian 100 users. The solution needs to integrate with the main web application and serve web content globally. The solution must also scale as to company's user base grows while providing lowest login latency possible.

1. A. Use Amazon Cognito tor authenticatio
2. B. Use Lambda#Edge tor authorization Use Amazon CloudFront 10 serve the web application globally
3. C. Use AWS Directory Service for Microsoft Active Directory tor authentication Use AWS Lambda for authorization Use an Application Load Balancer to serve the web application globally
4. D. Usa Amazon Cognito for authentication Use AWS Lambda tor authorization Use Amazon S3 Transfer Acceleration 10 serve the web application globally.
5. E. Use AWS Directory Service for Microsoft Active Directory for authentication Use Lambda@Edge for authorization Use AWS Elastic Beanstalk to serve the web application.

Correct Answer: A

A company wants to reduce the cost of its existing three-tier web architecture. The web, application, and database servers are running on Amazon EC2 instances for the development, test, and production environments. The EC2 instances average 30% CPU utilization during peak hours and 10% CPU utilization during non-peak hours.
The production EC2 instances run 24 hours a day. The development and test EC2 instances run for at least 8 hours each day. The company plans to implement automation to stop the development and test EC2 instances when they are not in use.
Which EC2 instance purchasing solution will meet the company's requirements MOST cost-effectively?

1. A. Use Spot Instances for the production EC2 instance
2. B. Use Reserved Instances for the development and test EC2 instances.
3. C. Use Reserved Instances for the production EC2 instance
4. D. Use On-Demand Instances for the development and test EC2 instances.
5. E. Use Spot blocks for the production EC2 instance
6. F. Use Reserved Instances for the development and test EC2 instances.
7. G. Use On-Demand Instances for the production EC2 instance
8. H. Use Spot blocks for the development and test EC2 instances.

Correct Answer: B
