The answer is 5 minutes of data loss. This is correct because Azure Site Recovery data loss calculation recovery point analysis hinges on the last available recovery point before the failure, not the failover time. The primary region failed at 10:35 AM, and the last recovery point was at 10:30 AM, so any writes between 10:30 and 10:35 are lost—exactly five minutes of data. On the AZ-305 exam, this scenario tests your understanding that actual data loss is determined by the gap between the last recovery point and the failure event, not the RPO policy setting or the failover initiation time. A common trap is confusing the policy-defined RPO (e.g., 15 minutes) with the real loss, which is always based on the last successful replication timestamp. Remember: loss stops when the failure happens, not when you click failover. Memory tip: “Failure time minus last recovery point equals real loss.”
AZ-305 Design business continuity solutions Practice Question
This AZ-305 practice question tests your understanding of design business continuity solutions. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. 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.
Refer to the exhibit. You are reviewing an Azure Site Recovery replicated item for a VM. The replication health is Normal, and the last recovery point is at 10:30 AM. The primary region experiences a failure at 10:35 AM. You initiate a failover at 10:40 AM. What is the maximum potential data loss?

Correct answer & explanation
✓
5 minutes of data
Option A is correct because the last recovery point is at 10:30 AM, and the failure occurred at 10:35 AM. The data loss is up to 5 minutes of data (between 10:30 and 10:35). Option B is wrong because the RPO is defined by the policy, but the actual loss is based on the last recovery point. Options C and D are incorrect.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Real-world example
How this comes up in practice
An e-commerce site experiences heavy traffic on Black Friday and near-zero traffic during off-peak weeks. Rather than provisioning permanent large VMs, the team uses auto-scaling groups that add capacity automatically under load and reduce it overnight. Questions like this test whether you understand elasticity, availability zones, and cloud compute scaling patterns.
