A company runs an application on AWS. The company curates data from several different sources. The company uses proprietary algorithms to perform data transformations and aggregations. After the company performs E TL processes, the company stores the results in Amazon Redshift tables. The company sells this data to other companies. The company downloads the data as files from the Amazon Redshift tables and transmits the files to several data customers by using FTP. The number of data customers has grown significantly. Management of the data customers has become difficult.
The company will use AWS Data Exchange to create a data product that the company can use to share data with customers. The company wants to confirm the identities of the customers before the company shares data. The customers also need access to the most recent data when the company publishes the data.
Which solution will meet these requirements with the LEAST operational overhead?

1. A. Use AWS Data Exchange for APIs to share data with customer
2. B. Configure subscription verification In the AWS account of the company that produces the data, create an Amazon API Gateway Data API service integration with Amazon Redshif
3. C. Require the data customers to subscribe to the data product In the AWS account of the company that produces the data, create an AWS Data Exchange datashare by connecting AWS Data Exchange to the Redshift
4. D. cluste
5. E. Configure subscription verificatio
6. F. Require the data customers to subscribe to the data product.
7. G. Download the data from the Amazon Redshift tables to an Amazon S3 bucket periodicall
8. H. Use AWS Data Exchange for S3 to share data with customers.
9. I. Configure subscription verificatio
10. J. Require the data customers to subscribe to the data product Publish the Amazon Redshift data to an Open Data on AWS Data Exchang
11. K. Require the customers to subscribe to the data product in AWS Data Exchang
12. L. In the AWS account of the company that produces the data, attach IAM resource-based policies to the Amazon Redshift tables to allow access only to verified AWS accounts.

Correct Answer: D

A solutions architect works for a government agency that has strict disaster recovery requirements All Amazon Elastic Block Store (Amazon EBS) snapshots are required to be saved in at least two additional AWS Regions. The agency also is required to maintain the lowest possible operational overhead.
Which solution meets these requirements?

1. A. Configure a policy in Amazon Data Lifecycle Manager (Amazon DLMJ to run once daily to copy the EBS snapshots to the additional Regions.
2. B. Use Amazon EventBridge (Amazon CloudWatch Events) to schedule an AWS Lambda function to copy the EBS snapshots to the additional Regions.
3. C. Set up AWS Backup to create the EBS snapshot
4. D. Configure Amazon S3 cross-Region replication to copy the EBS snapshots to the additional Regions.
5. E. Schedule Amazon EC2 Image Builder to run once daily to create an AMI and copy the AMI to the additional Regions.

Correct Answer: B

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?

1. A. Deploy a Lambda@Edge function to sort parameters by name and force them to be lowercas
2. B. Select the CloudFront viewer request trigger to invoke the function.
3. C. Update the CloudFront distribution to disable caching based on query string parameters.
4. D. Deploy a reverse proxy after the load balancer to post-process the emitted URLs in the application to force the URL strings to be lowercase.
5. E. Update the CloudFront distribution to specify casing-insensitive query string processing.

Correct Answer: A
https://docs.amazonaws.cn/en_us/AmazonCloudFront/latest/DeveloperGuide/lambda-examples.html#lambda-ex Before CloudFront serves content from the cache it will trigger any Lambda function associated with the
Viewer Request, in which we can normalize parameters.

A solutions architect is designing the data storage and retrieval architecture for a new application that a company will be launching soon. The application is designed to ingest millions of small records per minute from devices all around the world. Each record is less than 4 KB in size and needs to be stored in a durable location where it can be retrieved with low latency. The data is ephemeral and the company is required to store the data for 120 days only, after which the data can be deleted.
The solutions architect calculates that, during the course of a year, the storage requirements would be about 10-15 TB.
Which storage strategy is the MOST cost-effective and meets the design requirements?

1. A. Design the application to store each incoming record as a single .csv file in an Amazon S3 bucket to allow for indexed retrieva
2. B. Configure a lifecycle policy to delete data older than 120 days.
3. C. Design the application to store each incoming record in an Amazon DynamoDB table properly configured for the scal
4. D. Configure the DynamoOB Time to Live (TTL) feature to delete records older than 120 days.
5. E. Design the application to store each incoming record in a single table in an Amazon RDS MySQL databas
6. F. Run a nightly cron job that executes a query to delete any records older than 120 days.
7. G. Design the application to batch incoming records before writing them to an Amazon S3 bucke
8. H. Update the metadata for the object to contain the list of records in the batch and use the Amazon S3 metadata search feature to retrieve the dat
9. I. Configure a lifecycle policy to delete the data after 120 days.

Correct Answer: B
DynamoDB with TTL, cheaper for sustained throughput of small items + suited for fast retrievals. S3 cheaper for storage only, much higher costs with writes. RDS not designed for this use case.

A company wants to change its internal cloud billing strategy for each of its business units. Currently, the cloud governance team shares reports for overall cloud spending with the head of each business unit. The company uses AWS Organizations lo manage the separate AWS accounts for each business unit. The existing tagging standard in Organizations includes the application, environment, and owner. The cloud governance team wants a centralized solution so each business unit receives monthly reports on its cloud spending. The solution should also send notifications for any cloud spending that exceeds a set threshold.
Which solution is the MOST cost-effective way to meet these requirements?

1. A. Configure AWS Budgets in each account and configure budget alerts that are grouped by application, environment, and owne
2. B. Add each business unit to an Amazon SNS topic for each aler
3. C. Use Cost Explorer in each account to create monthly reports for each business unit.
4. D. Configure AWS Budgets in the organization's master account and configure budget alerts that are grouped by application, environment, and owne
5. E. Add each business unit to an Amazon SNS topic for each aler
6. F. Use Cost Explorer in the organization's master account to create monthly reports for each business unit.
7. G. Configure AWS Budgets in each account and configure budget alerts lhat are grouped by application, environment, and owne
8. H. Add each business unit to an Amazon SNS topic for each aler
9. I. Use the AWS Billing and Cost Management dashboard in each account to create monthly reports for each business unit.
10. J. Enable AWS Cost and Usage Reports in the organization's master account and configure reports grouped by application, environment, and owne

Correct Answer: B
Configure AWS Budgets in the organization€™s master account and configure budget alerts that are grouped by application, environment, and owner. Add each business unit to an Amazon SNS topic for each alert. Use Cost Explorer in the organization€™s master account to create monthly reports for each business unit.
