Question 1

You are designing the caching strategy for a global web application.

The application relies on Azure Cache for Redis to store session state and reference data. You need to ensure that the Redis cache is highly available, survives a datacenter failure, and can scale beyond the memory limits of a single VM node.

Which Azure Cache for Redis tier should you recommend?

Accepted Answer

Look for 'survives datacenter failure' (Availability Zones) and 'scale beyond memory limits' (Clustering). Both require the Premium tier.

Question 2
