Exam AWS Certified Developer - Associate DVA-C02 topic 1 question 11 discussion

B. Store each employee's contact information in an Amazon DynamoDB table along with the object keys for the photos stored in Amazon S3. Storing each employee's contact information in an Amazon DynamoDB table along with the object keys for the photos stored in Amazon S3 provides a scalable and efficient solution for storing and retrieving employee details and high-resolution photos using AWS APIs. The developer can use the DynamoDB table to query and retrieve employee details, while the S3 bucket can be used to store the high-resolution photos. By using S3, the solution can support large amounts of data while enabling fast retrieval times. The combination of DynamoDB and S3 can provide a cost-effective and scalable solution for storing employee data and photos.

This is the best solution because it uses AWS-native services that are scalable, serverless, and fully managed

A) Eliminated - DynamoDB is not cost-effective for storing large binary data and also increases query latency C) Eliminated - Cognito user pools are intended for user authentication and authorization, not as a storage solution

==> discard A: store image in db, will enhance time query ==> discard C: cognito for idetifying not querying info ==> discard D: EFS vs S3, I choose s3, its storage is global, best popular to store image than EFS, with EFS you must use EC2, how you can link image in EC2 with db ==> B is best choice

A: Base 64 is a distraction. You can use encryption at rest using KMS for most things. Would you store photos in DynamoDB? Would be silly C. Cognito has nothing to do with the question. Question is asking about searching for employee details D. Could work, but seems convoluted. Relational DBs are easily searchable, but how would you link the db to the image in EC2? B is the simplest and correct answer here.

B is the correct answer.

Answer is B

I agree, B is correct, DynamoDB to store user's data along the Key for S3 objects knowing that S3 is a good solution to store large amount of data or "high quality" images

DynamoDb + S3 is the best option for those scenaries

DynamoDB is very fast, secure, and scalable. The S3 is very in-expensive, virtually limitless, and can handle large files. So B is the correct answer.

A. is not really clear to me, however encoding all info in base64 would make search a bit complex C. does not provide a solution for high resolution image D. EFS does not provide API access to content

Option B. As the question says that we have to store high-resolution photos, the solution is to use the S3 here. Because, DynamoDb cannot be used to store anything that is above 400 KB for each object. In this case, we can use DynamoDb to store the contact information of each of the employees and reference the object keys in the table to retrieve the high-resolution images.

Agreed with B
