Last verified against current AWS documentation ·How we write our questions

An insurance company in Germany runs a claims assistant on Amazon Bedrock. Claims contain personal data, and company policy requires that inference requests stay within the European Union.

Traffic is steady during the day, but after a storm many claims arrive at once, and requests are throttled in the home Region. The company must absorb these spikes without a drop in answer quality.

The monthly budget does not allow paying for peak capacity around the clock.

Which solution meets these requirements?

Choose one answer.

  1. A. Call a global cross-Region inference profile, so that requests route to any commercial Region with spare capacity and the assistant gets the most throughput.
  2. B. Keep on-demand calls in the home Region, add exponential backoff with jitter to every request, and request a quota increase ahead of the storm season.
  3. C. Call a geographic cross-Region inference profile for the European Union, which routes each request only among EU Regions, and keep the application's retry logic in place.
  4. D. Buy Provisioned Throughput with model units sized for the peak hour in the home Region, so capacity is always reserved for the claims assistant and throttling stops.
Show the answer and explanation

Answer: C

  • A. Wrong: A global profile can send requests to Regions outside the European Union, which breaks the data residency policy. It solves the throttling but not the rule that personal data stays within the EU.
  • B. Wrong: Backoff spreads retries over time, but it does not add capacity during a sharp spike, so claims may still wait too long. A quota increase can take time to approve and may not cover the spike size.
  • C. Right: A geographic profile adds capacity from several EU Regions when the home Region is throttled, and it pays on demand, so no peak capacity is bought in advance. Requests never leave the European Union, which meets the residency policy and the budget. Learn more: Geographic cross-Region inference (opens in a new tab)
  • D. Wrong: Provisioned Throughput would stop the throttling, but the commitment is paid every hour, including the quiet periods. That cost is what the budget rules out, so this option misses the cost requirement.

Explanation

A geographic cross-Region inference profile lets requests spill over to other EU Regions during spikes, so capacity grows without leaving the EU and without a fixed monthly commitment. Global profiles break residency, backoff and quota increases do not add capacity fast enough, and Provisioned Throughput costs money during quiet hours.
