A developer wants to store information about movies. Each movie has a title, release year, and genre. The movie information also can include additional properties about the cast and production crew. This additional information is inconsistent across movies. For example, one movie might have an assistant director, and another movie might have an animal trainer.
The developer needs to implement a solution to support the following use cases:
For a given title and release year, get all details about the movie that has that title and release year. For a given title, get all details about all movies that have that title.
For a given genre, get all details about all movies in that genre. Which data store configuration will meet these requirements?

1. A. Create an Amazon DynamoDB tabl
2. B. Configure the table with a primary key that consists of the title as the partition key and the release year as the sort ke
3. C. Create a global secondary index that uses the genre as the partition key and the title as the sort key.
4. D. Create an Amazon DynamoDB tabl
5. E. Configure the table with a primary key that consists of the genre as the partition key and the release year as the sort ke
6. F. Create a global secondary index that uses the title as the partition key.
7. G. On an Amazon RDS DB instance, create a table that contains columns for title, release year, and genre.Configure the title as the primary key.
8. H. On an Amazon RDS DB instance, create a table where the primary key is the title and all other data is encoded into JSON format as one additional column.

A financial company must store original customer records for 10 years for legal reasons. A complete record contains personally identifiable information (PII). According to local regulations, PII is available to only certain people in the company and must not be shared with third parties. The company needs to make the records available to third-party organizations for statistical analysis without sharing the PII.
A developer wants to store the original immutable record in Amazon S3. Depending on who accesses the S3 document, the document should be returned as is or with all the PII removed. The developer has written an AWS Lambda function to remove the PII from the document. The function is named removePii.
What should the developer do so that the company can meet the PII requirements while maintaining only one copy of the document?

1. A. Set up an S3 event notification that invokes the removePii function when an S3 GET request is made.Call Amazon S3 by using a GET request to access the object without PII.
2. B. Set up an S3 event notification that invokes the removePii function when an S3 PUT request is made.Call Amazon S3 by using a PUT request to access the object without PII.
3. C. Create an S3 Object Lambda access point from the S3 consol
4. D. Select the removePii functio
5. E. Use S3 Access Points to access the object without PII.
6. F. Create an S3 access point from the S3 consol
7. G. Use the access point name to call the GetObjectLegalHold S3 API functio
8. H. Pass in the removePii function name to access the object without PII.
