Question 2easymultiple choice
Full question →A company has virtual machines in Azure that need to be grouped across multiple fault domains and update domains to ensure high availability. They plan to deploy three VMs running the same application tier. Which Azure feature should they use to provide redundancy within a single region?
Question 3mediummultiple choice
Full question →A company runs a critical web application on Azure App Service in a single region. They need to achieve high availability across regions with automatic failover in the event of a regional outage. Which approach should they recommend?
Question 4hardmultiple choice
Full question →A company deploys a multi-tier web application on Azure VMs across availability zones. The web tier must have SSL termination, session persistence, and health probe monitoring. Additionally, all traffic must be inspected by a central firewall for compliance. The solution must be highly available. Which combination of Azure services should they implement?
Question 5mediummultiple choice
Full question →A company plans to deploy multiple virtual machines (VMs) across two Azure regions for high availability. The VMs will host a stateless web application that must be accessible via a single DNS endpoint. The solution must automatically route traffic to the nearest region with available capacity and provide failover if a region becomes unhealthy. Which Azure service should they use to meet these requirements?
Question 6mediummultiple choice
Full question →A company needs a fully managed NoSQL database for a JSON document-oriented application that requires low latency (single-digit milliseconds) for reads and writes at any scale. The application will run globally and needs multi-region writes with automatic failover. Which Azure data store should they use?
Question 7mediummultiple choice
Full question →A company has two on-premises data centers and an Azure subscription. They need to connect each data center to Azure with a private, high-bandwidth, and reliable connection. They also want a low-cost backup connection for each data center in case the primary connection fails. Which combination of connectivity options should they recommend?
Question 8mediummultiple choice
Full question →A company plans to deploy a multi-tier application on Azure. The web tier requires SSL termination and health probes. The application tier must be isolated from the internet. The database tier requires high availability. They want to minimize administrative overhead and use Azure native services. Which architecture should they recommend?
Question 9easymultiple choice
Full question →A company plans to deploy a web application on Azure virtual machines. They want to protect against a datacenter failure within a region. The VMs must be distributed across multiple physically separate locations with independent power, cooling, and networking. Which deployment option should they use?
Question 10mediummultiple choice
Full question →A company wants to deploy a web application on Azure virtual machines (VMs). The application experiences variable traffic patterns, so the company needs to automatically add or remove VM instances based on CPU utilization. They also want the application to remain highly available even if an Azure datacenter fails. Which combination of Azure services should they use?
Question 11easymultiple choice
Full question →A company stores large video files for a media streaming application. The files are accessed infrequently but need to be available instantly when requested. The company wants to minimize storage costs while ensuring high durability. Which Azure Blob Storage access tier should they use?
Question 12mediummultiple choice
Full question →A company runs SQL Server on an Azure virtual machine. They need to automate database backups with application-consistency and retain backups for 10 years to meet compliance. They also want to restore to any point in time within the last 35 days. Which Azure Backup solution should they use?
Question 13easymultiple choice
Full question →A startup is building a new mobile app backend. They need a fully managed relational database service with built-in high availability, automatic backups, and built-in intelligence to optimize performance. They want to minimize administrative overhead for tasks like patching and scaling. Which Azure service should they use?
Question 14mediummultiple choice
Full question →A global company stores customer profile data in JSON format. The application requires low-latency writes and reads from multiple regions. The solution must support multi-region writes with automatic conflict resolution and provide high availability. Which Azure Cosmos DB configuration should they choose?
Question 15easymultiple choice
Full question →A company deploys a stateless web application on Azure VMs in a single region. They need to distribute incoming HTTP traffic across multiple VMs and perform health checks. The solution should be highly available within the region. Which Azure load balancing solution should they use?
Question 16hardmultiple choice
Full question →A company runs a critical SQL Server database on an Azure virtual machine. They need a high-availability solution within a single region that provides automatic failover, zero data loss (synchronous replication), and support read-only routing for reporting workloads. Which solution should they implement?
Question 17mediummultiple choice
Full question →A company runs a critical SQL Server database on Azure Virtual Machines in a single region. They need a disaster recovery solution across regions with a recovery point objective (RPO) of zero. The database is update-intensive with frequent writes. Which configuration should they implement?
Question 18hardmultiple choice
Full question →A company runs a high-performance computing (HPC) workload on Azure that requires extremely low latency (under 10 microseconds) between multiple VMs for MPI communication. The VMs are part of a single job and must be placed together to minimize network latency. Which VM deployment option should they use?
Question 19easymultiple choice
Full question →A company runs a global e-commerce application that needs to store product catalog data. The data is JSON documents with variable schemas. The application requires single-digit millisecond read and write latencies at any scale and must support automatic synchronous replication across multiple Azure regions for high availability and low latency reads from any region. Which Azure data service should they choose?
Question 20mediummultiple choice
Full question →A company runs a stateless web application on Azure VMs. They need to ensure the application remains available in the event of an entire Azure datacenter failure. They want to achieve a 99.99% SLA. Which deployment option should they recommend?
Watch out for

- ▸Answering from memory before reading the full scenario.
- ▸Missing a constraint such as cost, availability, security, scope or command context.
- ▸Choosing a broad answer when the question asks for the most specific fix.
- ▸Ignoring why the wrong options are tempting.

Frequently asked questions
- What does the AZ-305 exam test about High Availability?
- High Availability questions test whether you can apply the concept in context, not just recognise a definition.
- How should I use these practice questions?
- Select your answer before revealing the explanation. Then read why each option is right or wrong — this active recall approach builds retention far faster than re-reading notes.
- Can I practise just High Availability questions in a focused session?
- Yes — the session launcher on this page draws every question from the High Availability domain. Use a 10-question session first to gauge your baseline, then move to 20 or 30 once the weak spots are clear.
- Where can I practise other AZ-305 topics?
- Use the topic links above to move to related areas, or go back to the AZ-305 question bank to see all topics.
- Are these real exam questions or dumps?
- These are original practice questions written to test the same concepts the AZ-305 exam covers. They are not copied from any real exam or dump site.
