Microsoft Azure Architect Design (2020, legacy) — Question 54

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?

Answer options

• 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.

Correct answer: D

Explanation

The correct answer is D because increasing the number of key vaults allows for higher throughput by distributing the load across multiple vaults. Changing the pricing tier (A) may not effectively resolve throttling issues, while geo-replication (B) and load balancing (C) are not directly applicable to increasing the throughput of a single key vault in this context.
