AZ-304 Microsoft Azure Architect Design 2

Question 1

A company needs to ensure their Azure SQL Database can failover to a secondary region within 30 seconds with zero data loss. Which feature should the architect configure?

Accepted Answer

Auto-failover groups with synchronous commit

Answer

Auto-failover groups support automatic failover with a configurable grace period, and when configured with synchronous replication, they provide zero data loss (RPO=0).

Question 2

An architect must design a solution where an Azure Function triggers whenever a blob is added to Azure Storage. The solution must handle millions of events daily with guaranteed delivery. Which approach is best?

Accepted Answer

Use Event Grid with Azure Functions as the subscriber

Answer

Event Grid provides near-real-time event delivery with at-least-once delivery guarantees and scales to millions of events per second, making it ideal for large-scale blob event processing.

Question 3

A design requires that only users from a specific Azure AD group can access an Azure API Management API during business hours. Which APIM policy combination achieves this?

Accepted Answer

validate-jwt + check-header policies

Answer

The validate-jwt policy validates the AAD token and checks group membership claims, while check-header can enforce time-of-day restrictions via custom headers injected upstream.

Question 4

You are designing a multi-tenant SaaS application on Azure. Each tenant requires data isolation with separate encryption keys. Which Azure storage approach best satisfies this requirement?

Accepted Answer

Separate Azure SQL databases per tenant with customer-managed keys in Azure Key Vault

Answer

Separate databases per tenant with customer-managed keys (CMK) in Azure Key Vault provides true data isolation and independent key management per tenant.

Question 5

An architect needs to design a solution that caches API responses for 5 minutes globally but invalidates the cache immediately when data changes. Which Azure services should be combined?

Accepted Answer

Azure API Management with built-in cache + Event Grid for invalidation

Answer

Azure API Management's built-in cache can store responses, and Event Grid events can trigger cache invalidation policies via APIM's external cache invalidation capabilities.
