weather-tracking application is built using Amazon DynamoDB. The performance of the application has been consistently good. But lately, the team has realized that during holidays and travel seasons, the load on the application is high and the read requests consume most of the database resources, thereby drastically increasing the overall application latency. Which feature/service will help resolve this issue?Question 63Answera.Amazon CloudFrontb.Amazon DynamoDB Acceleratorc.Amazon DynamoDB Regulatord.Amazon ElastiCache

A Company is designing a high availability solution for a customer. This customer's requirements are that their application needs to be able to handle an unexpected amount of load and allow site visitors to read data from a DynamoDB table, which contains the results of an online polling system. Given this information, what would be the best and most cost-saving method for architecting and developing this application?Select one:a. Use the JavaScript SDK and build a static HTML page, hosted inside of an Amazon S3bucket; use CloudFront and Route 53 to serve the website, which uses JavaScript client-sidelanguage to communicate with DynamoDBb. Create a CloudFront distribution that serves the HTML web page, but send the visitors to an Auto Scaling ELB application pointing to EC2 instances c. Create a Lambda script, which pulls the most recent DynamoDB polling results and creates a custom HTML page, inside of Amazon S3 and use CloudFront and Route 53 to servethe static websited. Deploy an Auto Scaling application with Elastic Load Balancer pointing to EC2 instances that use a server-side SDK to communicate with the DynamoDB table
