Your company wants to expose their services to external developers as public APIs. They want to do this for monetization, visibility and engagement that results in growth. They also want to throttle requests to those APIs based on defined limits and quotas.What service would you suggest to meet the requirements?AWS AppSyncApplication Load BalancerAmazon API GatewayLambda Function URL

Which platform for developing and managing API proxies has a specific focus on business problems, like rate limiting, quotas, and analytics?Cloud EndpointsREST APIApigee API ManagementPub/Sub

As a Solutions Architect for an e-commerce company, you are asked to improve the overall performance of an application that is behind Amazon API Gateway. You also need to protect the backend system and the application from traffic spikes.What is the optimal solution that you would recommend?Enable API Gateway to automatically scale and set throttling limitsEnable caching and set throttling limits.Enable caching and scale API gateway services.Enable caching and WAF (Web Application Firewall)

You are consulting for a company that promotes large musical events. They are going to announce a concert of a well known artist and expect a 10 fold increase in requests to their service. The service is based on API Gateway triggering a series of Lambda functions and an Amazon Relational Database Service (Amazon RDS) Database for persistent storage.What suggestions would you make for cost effective scaling?Set Lambda provisioned concurrency to a value that meets your cost targetEnable API Gateway caching to reduce backend invocationsScale the Amazon RDS instance up during the peak request periodUse API Keys to rate limit incoming user requests

What AWS service provides a web services interface that can be used to store and retrieve unlimited amounts of data, at any time, from anywhere on the Web?

A company will be modernizing their application which is currently running on Amazon Elastic Cloud Compute (EC2) instances. They have experience with scaling this infrastructure using Amazon EC2 Autoscaling. They want to move to serverless infrastructure consisting of an Amazon API Gateway that triggers Lambda functions. They are consulting you about scaling this new infrastructure.What should the company consider in order to make sure the serverless infrastructure scales to their needs?Throttle Lambda functions by configuring reserved concurrency, sending the excess traffic to Dead Letter Queues (DLQ) that will be handled when the request volume reduces.Look at service limits for Amazon API Gateway and Lambda functions used in order to identify potential bottlenecks and balance performance requirements, costs, and business impactEnable Auto Scaling Groups for AWS Lambda to ensure that enough Lambda functions are ready to handle the incoming requestsDo nothing. API Gateway and AWS Lambda are managed services that have built-in horizontal scaling, security, and high availability to handle unlimited amount of requests
