AZ-305 · Question 01 · Domain 1.1: Logging and Monitoring

Contoso Ltd has 50 subscriptions across 3 business units. Each business unit manages its own IT operations. You are designing a logging and monitoring solution using Azure Monitor and Log Analytics.

The company requires that each business unit has full control over its own logs, but the central security team must be able to query security logs across all business units simultaneously. You need to minimize administrative overhead and cost.

Which Log Analytics workspace architecture should you recommend?

Answer options:

A.

Create a single centralized Log Analytics workspace for the entire company. Use workspace-level RBAC to restrict access.

B.

Create one Log Analytics workspace per business unit. Grant the central security team Reader access to all workspaces and use cross-workspace queries.

C.

Create one Log Analytics workspace per subscription (50 total). Use Azure Lighthouse for central management.

D.

Create one Log Analytics workspace per business unit. Configure continuous export to a central Azure Data Lake Storage Gen2 account for the security team.

How to approach this question

Analyze the organizational boundaries. When business units need autonomy but central teams need visibility, a distributed workspace model with cross-workspace queries is the standard Azure Monitor pattern.

Create one Log Analytics workspace per business unit. Grant the central security team Reader access to all workspaces and use cross-workspace queries.
In enterprise scenarios where data sovereignty or strict administrative boundaries exist between business units, a distributed Log Analytics workspace design is recommended. To satisfy central visibility requirements (like a SOC team), Azure Monitor supports cross-workspace queries, allowing you to query up to 100 workspaces simultaneously without duplicating data.

Common mistakes

Choosing a single centralized workspace is a common mistake when ignoring the 'business unit control' requirement.
