A company has a complex web application that leverages Amazon CloudFront for global scalability and performance. Over time, users report that the web application is slowing down.

The company's operations team reports that the CloudFront cache hit ratio has been dropping steadily. The cache metrics report indicates that query strings on some URLs are inconsistently ordered and are specified sometimes in mixed-case letters and sometimes in lowercase letters.

Which set of actions should the solutions architect take to increase the cache hit ratio as quickly as possible?

Options

ADeploy a Lambda@Edge function to sort parameters by name and force them to be lowercase. Select the CloudFront viewer request trigger to invoke the function.

BUpdate the CloudFront distribution to disable caching based on query string parameters.

CDeploy a reverse proxy after the load balancer to post-process the emitted URLs in the application to force the URL strings to be lowercase.

DUpdate the CloudFront distribution to specify casing-insensitive query string processing.

A company is running an Apache Hadoop cluster on Amazon EC2 instances. The Hadoop cluster stores approximately 100 TB of data for weekly operational reports and allows occasional access for data scientists to retrieve dat

a. The company needs to reduce the cost and operational complexity for storing and serving this data.

Which solution meets these requirements in the MOST cost-effective manner?

Options

AMove the Hadoop cluster from EC2 instances to Amazon EMR. Allow data access patterns to remain the same.

BWrite a script that resizes the EC2 instances to a smaller instance type during downtime and resizes the instances to a larger instance type before the reports are created.

CMove the data to Amazon S3 and use Amazon Athena to query the data for reports. Allow the data scientists to access the data directly in Amazon S3.

DMigrate the data to Amazon DynamoDB and modify the reports to fetch data from DynamoDB. Allow the data scientists to access the data directly in DynamoDB.

MultipleChoice

A company runs a highly available data collection application on Amazon EC2 in the eu-north-1 Region. The application collects data from end-user devices and writes records to an Amazon Kinesis data stream and a set of AWS Lambda functions that process the records The company persists the output of the record processing to an Amazon S3 bucket in eu-north-1. The company uses the data in the S3 bucket as a data source for Amazon Athena

Options

AIn each of the Iwo new Regions set up the Lambda functions to run in a VPC Set up an S3 gateway endpoint in that VPC

BTurn on S3 Transfer Acceleration on the S3 bucket in eu-north-1 Change the application to use the new S3 accelerated endpoint when the application uploads data to the S3 bucket

CCreate an S3 bucket in each of the two new Regions Set the application in each new Region to upload to its respective S3 bucket Set up S3 Cross-Region Replication to replicate data to the S3 bucket in eu-north-1

DIncrease the memory requirements of the Lambda functions to ensure that they have multiple cores available Use the multipart upload feature when the application uploads data to Amazon S3 Lambda

MultipleChoice

A company wants to use Amazon S3 to back up its on-premises file storage solution. The company s on-premises file storage solution supports NFS and the company wants its new solution to support NFS The company wants to archive the backup Files after 5 days If the company needs archived files for disaster recovery, the company is willing to wait a few days for the retrieval of those Files.

Which solution meets these requirements MOST cost-effectively?

Options

ADeploy an AWS Storage Gateway file gateway that is associated with an S3 bucket Move the files from the on-premises file storage solution to the file gateway Create an S3 Lifecycle rule to move the files to S3 Standard-Infrequent Access (S3 Standard-IA) after 5 days

BDeploy an AWS Storage Gateway volume gateway that is associated with an S3 bucket Move the files from the on-premises file storage solution to the volume gateway Create an S3 Lifecycle rule to move the files to S3 Glacier Deep Archive after 5 days

CDeploy an AWS Storage Gateway tape gateway that is associated with an S3 bucket Move the files from the on-premises file storage solution to the tape gateway Create an S3 Lifecycle rule to move the files to S3 Standard-Infrequent Access (S3 Standard-IA) after 5 days

DDeploy an AWS Storage Gateway file gateway that is associated with an S3 bucket Move the files from the on-premises file storage solution to the file gateway Create an S3 Lifecycle rule to move the files to S3 Glacier Deep Archive after 5 days

MultipleChoice

A company is planning a large event where a promotional offer will be introduced The company's website is hosted on AWS and backed by an Amazon RDS for PostgreSQL DB instance The website explains the promotion and includes a sign-up page that collects user information and pReference Management expects large and unpredictable volumes of traffic periodically which will create many database writes A solutions architect needs to build a solution that does not change the underlying data model and ensures that submissions are not dropped before they are committed to the database

Which solutions meets these requirements'?

Options

AImmediately before the event, scale up the existing DB instance to meet the anticipated demand. Then scale down after the event

BUse Amazon SQS to decouple the application and database layers Configure an AWS Lambda function to write items from the queue into the database

CMigrate to Amazon DynamoDB and manage throughput capacity with automatic scaling

DUse Amazon ElastiCache for Memcached to increase write capacity to the DB instance
