The answer is that the storage account creation is denied. This occurs because the property supportsHttpsTrafficOnly has been deprecated and removed from the Azure Storage creation API as of late 2023; Azure now enforces HTTPS for all new storage accounts by default, so setting this property to false triggers a validation error that blocks the deployment. On the AZ-305 exam, this tests your awareness of Azure’s evolving security baselines and the deprecation lifecycle of ARM properties—a common trap is assuming you can still disable HTTPS enforcement on new accounts, but the platform no longer allows it. Remember the memory tip: “New accounts are HTTPS-only; false is a dead property.”
AZ-305 Design data storage solutions Practice Question
This AZ-305 practice question tests your understanding of design data storage 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.
Exhibit
Refer to the exhibit. The following is an Azure Policy definition:
{
"if": {
"field": "type",
"equals": "Microsoft.Storage/storageAccounts"
},
"then": {
"effect": "deny",
"details": {
"field": "Microsoft.Storage/storageAccounts/supportsHttpsTrafficOnly",
"equals": false
}
}
}
Refer to the exhibit. You attempt to create a new storage account with the property 'supportsHttpsTrafficOnly' set to false. What is the result?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The storage account creation is denied.
When you attempt to create a storage account with 'supportsHttpsTrafficOnly' set to false, Azure denies the creation because this property is deprecated and no longer accepted. As of late 2023, Azure Storage enforces HTTPS for all new storage accounts by default, and the property has been removed from the creation API. Setting it to false triggers a validation error, resulting in a denial of the creation request.
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.
✗
The storage account is created and an audit log is generated.
Why it's wrong here
The effect is deny, not audit.
✓
The storage account creation is denied.
Why this is correct
The policy denies creation when HTTPS is not enforced.
Related concept
Read the scenario before looking for a memorised answer.
✗
The storage account is created with HTTPS enforced automatically.
Why it's wrong here
The policy denies creation, it does not modify settings.
✗
The storage account is created but encryption is disabled.
Why it's wrong here
The policy does not mention encryption.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates assume the property still exists and can be set to false to disable HTTPS, but Azure has deprecated and removed it, causing the creation to be denied rather than silently ignoring the setting or allowing insecure traffic.
Detailed technical explanation
How to think about this question
The 'supportsHttpsTrafficOnly' property was part of the Azure Storage Resource Provider API version 2021-02-01 and earlier, but it has been deprecated in favor of the 'publicNetworkAccess' and 'minimumTlsVersion' properties. Under the hood, Azure's control plane validates all properties against the current API schema; any attempt to set a deprecated property to a non-compliant value (like false) results in an HTTP 400 Bad Request error. In real-world scenarios, this change prevents accidental creation of insecure storage accounts that could allow HTTP traffic, aligning with Azure's default security posture.

TExam Day Tips
→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.
