[All AWS Certified Big Data - Specialty Questions]

A company generates a large number of files each month and needs to use AWS import/export to move these files into Amazon S3 storage. To satisfy the auditors, the company needs to keep a record of which files were imported into Amazon S3.
What is a low-cost way to create a unique log for each import job?

  • A. Use the same log file prefix in the import/export manifest files to create a versioned log file in Amazon S3 for all imports.
  • B. Use the log file prefix in the import/export manifest files to create a unique log file in Amazon S3 for each import.
  • C. Use the log file checksum in the import/export manifest files to create a unique log file in Amazon S3 for each import.
  • D. Use a script to iterate over files in Amazon S3 to generate a log after each import/export job.

B is correct. Refer to https://aws.amazon.com/cn/blogs/aws/send-us-that-data/ - check the screenshots listed in the article. During manifest file creation we can specify "log file prefix"

Think C should actually work in practice. Howeer, two theoritcal issues come to my mind: 1. MD5 hashes could coincide accidentally, but chances for that are really, reaaaaally low. 2. MD5 hashes would also coincide if you sent the same log files twice (why would you tho). Overall, why provide cryptographic file names when you can just specify a log file prefix instead. B is better.

(checksums = MD5 hashes)
