Quick Answer
The answer is Azure Site Recovery, as it provides the cross-region disaster recovery capability needed for Azure Kubernetes Service (AKS) with stateful workloads. Azure Site Recovery orchestrates replication and automated failover of AKS clusters, including persistent volumes backed by Azure Disks, to a secondary region, minimizing data loss by leveraging crash-consistent or app-consistent snapshots. On the AZ-305 exam, this scenario tests your understanding of how to pair Azure Site Recovery with AKS for multi-region resilience, a common trap being to confuse traffic-routing services like Azure Traffic Manager or Azure Front Door with actual data replication and failover. Remember, Traffic Manager and Front Door handle load balancing and global routing, not stateful workload recovery, while Azure Backup for AKS is designed for backup and restore, not automated failover. A helpful memory tip: for cross-region DR of AKS with persistent volumes, think “ASR for AKS” — Azure Site Recovery handles the replication and failover, while other services only direct traffic or back up data.
This AZ-305 practice question tests your understanding of design business continuity solutions. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A company uses Azure Kubernetes Service (AKS) to run a containerized microservices application. They need a disaster recovery solution that can automatically fail over to a secondary region if the primary region fails. The solution must minimize data loss for stateful workloads. What should they implement?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "primary"
Why it matters: Asks for the main purpose or function, not a secondary benefit. Eliminate answers that describe side-effects or partial functions.
Clue: "minimum / minimize"
Why it matters: Asks for the least resource use — fewest addresses, smallest subnet, lowest overhead. Eliminate over-provisioned options even if they would technically work.
Azure Backup for AKS
Why wrong: Backup does not provide automatic failover.
Azure Front Door
Why wrong: Front Door is for global load balancing, not DR.
Azure Traffic Manager
Why wrong: Traffic Manager does not replicate data or fail over stateful workloads.
Azure Site Recovery
Site Recovery can replicate AKS workloads and persistent volumes for DR.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Azure Site Recovery
Option C is correct because AKS with Azure Disks using zone-redundant storage (ZRS) provides replication across zones within a region, but for cross-region DR, they need to pair with Azure Site Recovery or use a multi-region AKS with Velero for backup and restore. However, among the options, Azure Site Recovery is the only one that provides cross-region failover for AKS with persistent volumes. Option A is wrong because Azure Traffic Manager only routes traffic, does not replicate data. Option B is wrong because Azure Front Door is for global load balancing, not DR. Option D is wrong because Azure Backup for AKS is backup-only, not failover.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
Azure Backup for AKS
Why it's wrong here
Backup does not provide automatic failover.
Azure Front Door
Why it's wrong here
Front Door is for global load balancing, not DR.
Azure Traffic Manager
Why it's wrong here
Traffic Manager does not replicate data or fail over stateful workloads.
Azure Site Recovery
Why this is correct
Site Recovery can replicate AKS workloads and persistent volumes for DR.

Common exam traps
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.
