Least Effort to Monitor S3 Incomplete Uploads and Versions

DEA-C01 By islever Editorial Last updated

Manage the lifecycle of data.

Short answer

C Use the Amazon S3 Storage Lens dashboard to gather the information on incomplete multipart uploads and outdated versions.

Question

A marketing company uses Amazon S3 to store marketing data. The company uses versioning in some buckets. The company runs several jobs to read and load data into the buckets. To help cost-optimize its storage, the company wants to gather information about incomplete multipart uploads and outdated versions that are present in the S3 buckets. Which solution will meet these requirements with the LEAST operational effort?
  1. Use AWS CLI to gather the information.
  2. Use Amazon S3 Inventory configurations reports to gather the information.
  3. Use the Amazon S3 Storage Lens dashboard to gather the information. Correct Answer
  4. Use AWS usage reports for Amazon S3 to gather the information.

Key Takeaways

The question tests knowledge of native S3 monitoring tools; the trap is choosing Inventory (B) which requires more setup and does not natively highlight 'incomplete uploads' as easily as Storage Lens.

AWS Storage Lens provides out-of-the-box metrics for incomplete multipart uploads and outdated object versions, offering the least operational effort compared to manual or custom reporting solutions.

Common mistake: Option B (S3 Inventory) is a common wrong choice because it generates detailed CSV/Parquet reports of all objects, but it lacks the pre-built dashboard insights for incomplete uploads that Storage Lens offers.

Expert Analysis

Why the Answer Is Correct

Correct answer: C — Use the Amazon S3 Storage Lens dashboard to gather the information. Amazon S3 Storage Lens automatically collects and visualizes usage metrics across your S3 buckets without requiring custom scripts or complex configurations. It includes specific default metrics for "Incomplete Multipart Uploads" and "Outdated Object Versions," allowing the marketing company to monitor these cost drivers immediately with zero code. This directly satisfies the requirement for the LEAST operational effort.

Why the Other Options Are Wrong

Option A (AWS CLI) requires writing and maintaining scripts to list and filter objects, representing high operational effort. Option B (S3 Inventory) provides detailed object-level data in files, but you must process these files to derive metrics like incomplete uploads, adding significant setup and maintenance overhead. Option D (AWS Usage Reports) provides aggregate billing data rather than granular storage status metrics needed for this specific optimization task.

Community Comment Notes

Community consensus strongly favors Storage Lens, with users noting that "Amazon S3 Storage Lens provides a comprehensive view... related to incomplete multipart uploads" (HagarTheHorrible). Some learners initially considered Inventory but were convinced by the ease of use argument for Storage Lens. One user confirmed the official documentation link supports this interpretation (emupsx1).

Exam Strategy

When asked for the 'least operational effort' or 'no code' solution for AWS monitoring, always look for managed dashboards or services (like CloudWatch, Storage Lens, or Trusted Advisor) before considering custom scripts or data export tools.

Frequently Asked Questions

Can S3 Inventory track incomplete multipart uploads?

S3 Inventory tracks object versions and sizes, but it does not natively report on incomplete multipart uploads. You would need additional processing logic to infer this state.

Is there any cost for using S3 Storage Lens?

S3 Storage Lens has a free tier for basic metrics. Advanced metrics may incur costs, but it remains significantly cheaper than building custom monitoring infrastructure.
