The correct answer is that this Azure Policy denies the creation or update of a storage account if its default blob service version is not set to '2020-10-02'. This policy enforces a specific service version for blob storage by blocking any deployment that either omits the defaultServiceVersion property or sets it to a different value, ensuring consistent API behavior and security compliance across all storage accounts. On the DP-203 exam, this question tests your understanding of Azure Policy effects—specifically the difference between Deny and Audit—and how policies can enforce configuration standards for data storage. A common trap is confusing a Deny effect with an Audit effect or assuming the policy only applies to accounts that already have a version set; in reality, it blocks any account missing the required version entirely. Memory tip: think of this policy as a strict bouncer—if your storage account doesn’t show the right ID ('2020-10-02'), it doesn’t get in.
DP-203 Practice Question: Secure, monitor, and optimize data storage and data processing
This DP-203 practice question tests your understanding of secure, monitor, and optimize data storage and data processing. 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.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Denies the creation or update of a storage account if its default blob service version is not set to '2020-10-02'
Option A is correct because the policy denies any storage account that does not have the default service version set to '2020-10-02'. Option B is wrong because it denies, not audits. Option C is wrong because it applies to all storage accounts, not just those with defaultServiceVersion set. Option D is wrong because it does not set the version; it denies if not set.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

For each option: why learners choose it and why it is or isn't the right answer here.
✓
Denies the creation or update of a storage account if its default blob service version is not set to '2020-10-02'
Why this is correct
The policy denies when the field does not equal the specified version.

Read the scenario before looking for a memorised answer.
✗
Sets the default blob service version of all storage accounts to '2020-10-02'
Why it's wrong here
The policy does not modify settings; it denies non-compliant resources.
✗
Audits storage accounts to check if their default blob service version is set to a value other than '2020-10-02'
Why it's wrong here
The effect is 'deny', not 'audit'.
✗
Denies the creation of storage accounts that have the default blob service version set to '2020-10-02'
Why it's wrong here
It denies when the version is not equal to '2020-10-02', not when it is equal.

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.
