The correct solution is to enable soft delete for Azure Files shares and configure share snapshots. Soft delete for Azure Files retains deleted files for up to 30 days by default, providing a safety net against accidental deletion or ransomware, while share snapshots offer point-in-time recovery to restore files from any moment within that retention window. On the AZ-305 exam, this scenario tests your understanding of native Azure Files protection mechanisms versus broader backup or sync services—a common trap is confusing Azure Backup for Azure Files (which creates scheduled recovery points but not the same 30-day soft delete window) or Azure File Sync (which only syncs, not recovers). Remember that soft delete is a share-level setting that works alongside snapshots for granular recovery, whereas replication options like LRS or GRS protect against hardware failure, not user error. Memory tip: think “soft delete + snapshots = 30-day safety net” to distinguish from backup or sync solutions.
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.
A company wants to protect its Azure Files shares from accidental deletion or ransomware. They need to be able to recover files from up to 30 days ago. What solution should they implement?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Enable soft delete for Azure Files shares and configure share snapshots
Option A is correct because Azure Files supports soft delete and file share snapshots (which are part of backup). Soft delete retains deleted files for up to 30 days by default. Option B is wrong because Azure Backup for Azure Files provides backup but not necessarily the 30-day recovery point needed. Option C is wrong because Azure File Sync syncs files but does not provide point-in-time recovery. Option D is wrong because Azure Storage replication options (LRS/GRS) do not protect against accidental deletion at the file level.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Sync the Azure Files share to an on-premises server using Azure File Sync
Why it's wrong here
Azure File Sync does not provide point-in-time recovery for accidental deletion.
✗
Use Azure Backup for Azure Files with a 30-day retention policy
Why it's wrong here
Azure Backup can provide this, but soft delete is simpler and more cost-effective for this requirement.
✗
Configure geo-redundant storage (GRS) for the storage account
Why it's wrong here
GRS protects against regional failure, not accidental deletion.
✓
Enable soft delete for Azure Files shares and configure share snapshots
Why this is correct
Soft delete retains deleted files for up to 30 days, and snapshots provide point-in-time recovery.

TExam Day Tips
→Underline the problem statement mentally.
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
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
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.
