2.0 Describe Azure architecture and services AZ-900 Practice Quiz

• A. An Azure region is a geographic area that contains one or more datacenters connected by a low-latency network
• B. Assume lower cost is automatic without managing usage
• C. Assume consumption-based pricing always costs less than reserved capacity
• D. Use Azure RBAC permissions on a subscription to grant access only at the resource group level

Azure regions provide locations where customers can deploy resources near users or compliance boundaries.

• A. Deploying near users can reduce latency for applications
• B. Use Azure Disk Storage for shared SMB file access from multiple Windows machines
• C. Treat the cloud provider as solely responsible for end-user data classification
• D. Use the cloud free tier to host long-term production workloads

Regional placement influences network distance between users and services.

• A. Rely on a single Availability Zone for production multi-tier workloads
• B. A region pair is a relationship between two Azure regions in the same geography for planned maintenance and recovery considerations
• C. Expect a public website to use a private-only cloud endpoint by default
• D. Disable Azure Monitor logging to reduce ingestion cost on production workloads

Region pairs help Azure coordinate updates and support regional recovery planning.

• A. Assume high availability is the same as disaster recovery
• B. Some organizations choose regions based on data residency rules
• C. Treat serverless as the same architecture as a long-running virtual machine
• D. Use a public cloud whenever data residency must remain on the customer premises

Compliance requirements can determine where data and workloads are hosted.

• A. Choose SaaS to build a brand-new custom application written from scratch
• B. Some Azure services support availability zones and others do not
• C. Skip Azure Policy and rely on team agreement to enforce naming and tagging
• D. Use one resource group for the entire subscription to simplify deletion

Service support must be checked before designing for zonal resilience.

• A. Skip tagging because Azure already groups resources by name
• B. Configure manual scaling for production workloads with unpredictable traffic spikes
• C. Sovereign regions are isolated Azure environments designed for specific government or compliance requirements
• D. Choose a model based on vendor preference rather than business requirements

Sovereign regions serve specialized regulatory and residency needs.

• A. Treat consumption-based pricing as a fixed-fee subscription independent of usage
• B. Use PaaS to build and manage every layer of the operating system and the runtime
• C. Availability zones are physically separate locations within an Azure region
• D. Treat Azure Functions as long-running background workers without time limits

Here, Availability zones help protect applications from failures in a single datacenter location.

• A. Use Azure Files for object storage of millions of unstructured photos and videos
• B. Treat Azure VPN Gateway as a substitute for Azure ExpressRoute in all scenarios
• C. Stop monitoring because the service is in the cloud
• D. Choosing a region can affect service availability, latency, compliance, and cost

Not every Azure service or price is identical in every region.
