A manufacturing firm has a large number of smart devices installed in various locations worldwide. Hourly logs from these devices are stored in an Amazon S3 bucket. Management is looking for comprehensive dashboards which should incorporate usages of these devices and forecast usage trends for these devices.
Which tool is the best suited to get this required dashboard?
A. Use S3 as a source for Amazon QuickSight and create dashboards for usage and forecast trends
B. Use S3 as a source for Amazon Redshift and create dashboards for usage and forecast trends
C. Copy data from Amazon S3 to Amazon DynamoDB. Use Amazon DynamoDB as a source for Amazon QuickSight and create dashboards for usage and forecast trends
D. Copy data from Amazon S3 to Amazon RDS. Use Amazon RDS as a source for Amazon QuickSight and create dashboards for usage and forecast trends

Your company uses an S3 bucket to store data for an application. Sometimes the team also downloads the S3 files for further analysis. As the data is very important, you need to protect against accidental deletions initiated by someone or an application and restore the files when needed.
Which of the following options is appropriate?
A. Enable the versioning feature in the S3 bucket.
B. Modify the S3 bucket to be read-only.
C. Use an S3 Lifecycle policy to transfer objects to a lower cost storage.
D. Enable the Server-Side Encryption with AWS KMS-Managed Keys (SSE-KMS).

You are requested to guide a large Pharma company. They are looking for a solution to save all their R&D test analysis data securely. Daily large numbers of reports are generated; this data would be accessed from multiple R&D centers spread across the globe. The company requires this data to be instantaneously available to all users.
Which of the following is the most suitable way for AWS storage to provide low latency access to users across the globe with the least cost?
A. Use Amazon EC2 instance with instance store to store data.
B. Use Amazon EFS volumes to store data.
C. Use Amazon EBS volumes connected to the EC2 instance to store data
D. Use Amazon S3 Standard storage class from Amazon S3 to store data.
Domain: Design for New Solutions
A new web application is designed by a developer team using Amazon API Gateway and AWS Lambda. REST APIs will be used for this purpose which will synchronously invoke the AWS Lambda function. The developer team is expecting a huge response to this application and looking for a secure solution for authenticating a large number of clients.
Which solution can be designed for this requirement in the most effective way?
A. Create a request parameter-based Lambda authorizer. Configure API Gateway to call Lambda authorizer to authenticate clients making a request using REST API.
B. Create users in Amazon Cognito user pools. Create an API Gateway authorizer with this user pool and enable the authorizer on the REST API.
C. Create resource policies matching specific users. Attach this resource policy to Amazon API Gateway which will control access to the APIs.
D. Create an IAM user policy to invoke API. Attach this policy to Amazon API Gateway which will control access to the APIs.
Domain: Continuous Improvement for Existing Solutions
A Java-based web application is migrated from On-premises to AWS. Amazon Elastic Beanstalk is used to deploy applications using ALB, Amazon EC2 instances in multiple AZ, and Amazon DynamoDB in provisioned capacity mode. Auto-scaling groups are created with general-purpose Amazon EC2 instances. Post-migration, customers observe a delayed response from web applications during busy hours. Further checks observed that the application performs a non-critical zip archive process causing load on the Amazon EC2 instance.
How can a solution be redesigned in a cost-effective way to get a better response from the web application?
A. Redeploy the application using Elastic Beanstalk worker environments with Amazon SQS and Amazon EC2 instance for the zip archive process. For the front-end, use the web server environment of ALB, Amazon EC2 instance, and Amazon DynamoDB.
B. Redeploy Auto Scaling groups with memory-intensive Amazon EC2 instance instead of general-purpose Amazon EC2 instance.
C. Redeploy application on Amazon EC2 instance with Elastic fabric Adaptor (EFA).
D. Redeploy the database layer with on-demand capacity mode instead of the provisioned capacity mode of the Amazon DynamoDB.
