A company hosts a data lake on AWS. The data lake consists of data in Amazon S3 and Amazon RDS for PostgreSQL. The company needs a reporting solution that provides data visualization and includes all the data sources within the data lake. Only the company's management team should have full access to all the visualizations. The rest of the company should have only limited access.
Which solution will meet these requirements?

1. A. Create an analysis in Amazon QuickSigh
2. B. Connect all the data sources and create new dataset
3. C. Publish dashboards to visualize the dat
4. D. Share the dashboards with the appropriate IAM roles.
5. E. Create an analysis in Amazon OuickSigh
6. F. Connect all the data sources and create new dataset
7. G. Publish dashboards to visualize the dat
8. H. Share the dashboards with the appropriate users and groups.
9. I. Create an AWS Glue table and crawler for the data in Amazon S3. Create an AWS Glue extract, transform, and load (ETL) job to produce report
10. J. Publish the reports to Amazon S3. Use S3 bucket policies to limit access to the reports.
11. K. Create an AWS Glue table and crawler for the data in Amazon S3. Use Amazon Athena Federated Query to access data within Amazon RDS for PoslgreSQ
12. L. Generate reports by using Amazon Athen
13. M. Publish the reports to Amazon S3. Use S3 bucket policies to limit access to the reports.

A company is hosting a web application on AWS using a single Amazon EC2 instance that stores
user-uploaded documents in an Amazon EBS volume. For better scalability and availability, the company duplicated the architecture and created a second EC2 instance and EBS volume in another Availability Zone placing both behind an Application Load Balancer After completing this change, users reported that, each time they refreshed the website, they could see one subset of their documents or the other, but never all of the documents at the same time.
What should a solutions architect propose to ensure users see all of their documents at once?

1. A. Copy the data so both EBS volumes contain all the documents.
2. B. Configure the Application Load Balancer to direct a user to the server with the documents
3. C. Copy the data from both EBS volumes to Amazon EFS Modify the application to save new documents to Amazon EFS
4. D. Configure the Application Load Balancer to send the request to both servers Return each document from the correct server.

Correct Answer: A
Amazon EFS provides file storage in the AWS Cloud. With Amazon EFS, you can create a file system, mount the file system on an Amazon EC2 instance, and then read and write data to and from your file system. You can mount an Amazon EFS file system in your VPC, through the Network File System versions 4.0 and a4.1 (NFSv4) protocol. We recommend using a current generation Linux NFSv4.1 client, such as those found in the latest Amazon Linux, Redhat, and Ubuntu AMIs, in conjunction with the Amazon EFS Mount Helper. For instructions, see Using the amazon-efs-utils Tools.
For a list of Amazon EC2 Linux Amazon Machine Images (AMIs) that support this protocol, see NFS Support. For some AMIs, you'll need to install an NFS client to mount your file system on your Amazon EC2 instance. For instructions, see Installing the NFS Client.
You can access your Amazon EFS file system concurrently from multiple NFS clients, so applications that scale beyond a single connection can access a file system. Amazon EC2 instances running in multiple Availability Zones within the same AWS Region can access the file system, so that many users can access and share a common data source.

2. B. Set up an S3 Lifecycle policy to transition objects to S3 Glacier Deep Archive after 2 years.
3. C. Use S3 Intelligent-Tierin
4. D. Activate the archiving option to ensure that data is archived in S3 Glacier Deep Archive.
5. E. Set up an S3 Lifecycle policy to transition objects to S3 One Zone-Infrequent Access (S3 One Zone-IA) immediately and to S3 Glacier Deep Archive after 2 years.

Correct Answer: B
