The answer is to enable blob versioning and enable soft delete for blobs. These two actions ensure data durability for a storage account using LRS by adding recovery layers beyond the three synchronous replicas within a single data center. Blob versioning preserves every overwrite as a separate version, while soft delete retains deleted blobs for a configurable retention period, allowing you to undo accidental deletions or modifications. On the AZ-204 exam, this scenario tests your understanding of how to protect against data loss when LRS offers no cross-region redundancy—a common trap is thinking you need geo-redundant storage instead. Remember that soft delete and versioning are complementary: versioning handles overwrites, soft delete handles deletions. For a memory tip, think “versions for overwrites, soft delete for deletes” to keep the two actions straight when choosing data protection options.
AZ-204 Develop for Azure storage Practice Question
This AZ-204 practice question tests your understanding of develop for azure storage. 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.
Which TWO actions should you take to ensure data durability for a storage account using LRS? (Choose two.)
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 blobs.
Enabling soft delete for blobs protects data by retaining deleted blobs for a specified retention period, allowing recovery from accidental deletion or overwrite. This directly enhances data durability within a single data center under LRS, as it provides an additional layer of protection beyond the three synchronous replicas.
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.
✓
Enable soft delete for blobs.
Why this is correct
Soft delete protects data from accidental deletion.
Related concept
Read the scenario before looking for a memorised answer.
✗
Assign RBAC roles to users.
Why it's wrong here
RBAC controls access, not data durability.
✓
Enable blob versioning.
Why this is correct
Versioning allows recovery from unintended overwrites or deletions.
Related concept

✗
Change replication to GRS.
Why it's wrong here
Although GRS improves durability, the question specifies using LRS.
✗
Configure network firewall rules.
Why it's wrong here
Firewall rules control network access, not durability.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse replication (GRS) with data protection features like soft delete and versioning, but the question explicitly asks for actions that ensure durability while keeping LRS, not changing the replication strategy.
Detailed technical explanation
How to think about this question
Soft delete works by marking blobs as logically deleted and moving them to a soft-deleted state, where they remain accessible for recovery during the retention period (default 7 days, configurable up to 365 days). Blob versioning complements this by preserving every write operation as a separate version, enabling point-in-time recovery even after overwrites or deletions. Together, these features provide a robust data protection strategy within a single LRS region, mitigating risks from application errors or accidental user actions.

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.
