Quick Answer
The answer is blob soft delete and versioning, as these two features work together to protect Azure Storage data from both accidental and malicious deletion. Blob soft delete retains deleted blobs for a configurable retention period, allowing recovery from inadvertent removal, while versioning preserves every overwrite as a separate version, enabling restoration to a prior state if a blob is maliciously overwritten or deleted. On the AZ-500 exam, this pairing tests your understanding of layered defense-in-depth for storage accounts, often appearing in scenario-based questions where you must choose the combination that prevents permanent data loss without relying on backups. A common trap is selecting only soft delete and forgetting versioning, which is critical for overwrite protection—soft delete alone cannot recover a blob that has been replaced. Remember the mnemonic “Save and Version” to recall that soft delete saves deleted blobs, and versioning saves overwritten states.
This AZ-500 practice question tests your understanding of secure compute, storage, and databases. 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 storage account contains regulated records. Which two features help protect against accidental or malicious deletion?
Blob soft delete and versioning
Correct for the stated requirement.
Disabling all encryption
Why wrong: This does not meet the stated requirement as directly as the correct option.
Public container access
Why wrong: This does not meet the stated requirement as directly as the correct option.
Immutable storage retention policies
Correct for the stated requirement.

Correct answer & explanation
Blob soft delete and versioning
Blob soft delete protects against accidental deletion by retaining deleted blobs for a specified retention period, allowing recovery. Versioning preserves previous versions of blobs, enabling restoration to an earlier state if malicious overwrites or deletions occur. Together, they provide a layered defense against both accidental and intentional data loss.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
The trap here is that candidates may confuse immutable storage retention policies (which prevent modification/deletion but are designed for compliance, not recovery from accidental deletion) with soft delete and versioning, which specifically address recovery after deletion.
Detailed technical explanation
Blob soft delete works by moving deleted blobs to a 'soft-deleted' state where they are invisible to normal list operations but remain recoverable via the Undelete Blob REST API (Set Blob Properties with x-ms-delete-snapshots). Versioning creates a new version ID for each write operation, allowing point-in-time recovery using the x-ms-version-id header. In a real-world scenario, a malicious script that deletes blobs can be mitigated by soft delete's retention policy (default 7 days, configurable up to 365 days) and versioning's ability to restore overwritten data.
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.

Same concept, more angles
These questions test the same concept from different angles. Work through them to make sure you can recognise it however the exam phrases it.
Variation 1. You are responsible for securing Azure Storage accounts that contain confidential documents. You need to implement a solution that prevents accidental deletion of storage accounts and ensures that deleted blobs can be recovered within 30 days. Which two actions should you take?
mediumWhy B: Option A is correct because a resource lock prevents deletion of the storage account. Option D is correct because soft delete for blobs allows recovery within the specified retention period. Option B (containers) is for versioning for blobs, not deletion prevention. Option C (immutability policy) is for legal hold, not recovery. Option E (firewall) is for access control.
