You have 500 Azure web apps in the same Azure region. The apps use a premium Azure key vault for authentication.
A developer reports that some authentication requests are being throttled.
You need to recommend a solution to increase the available throughput of the key vault. The solution must minimize costs.
What should you recommend?

A. Change the pricing tier.

B. Configure geo-replication.

C. Configure load balancing for the apps.

D. Increase the number of key vaults in the subscription.








 

Suggested Answer: D

To maximize your Key Vault through put rates, here are some recommended guidelines/best practices for maximizing your throughput:
1. Ensure you have throttling in place. Client must honor exponential back-off policies for 429's and ensure you are doing retries as per the guidance below.
2. Divide your Key Vault traffic amongst multiple vaults and different regions. Use a separate vault for each security/availability domain. If you have five apps, each in two regions, then we recommend 10 vaults each containing the secrets unique to app and region.
