The correct answer is to set 'supportsHttpsTrafficOnly' to true and 'minimumTlsVersion' to 'TLS1_2'. These two properties work together to enforce HTTPS traffic and mandate TLS 1.2 or higher for Azure storage accounts in an ARM template, directly meeting the security team’s mandate. The 'supportsHttpsTrafficOnly' property blocks all HTTP requests, while 'minimumTlsVersion' explicitly rejects connections using older, vulnerable TLS versions below 1.2. On the Microsoft Cybersecurity Architect exam, this tests your understanding of Azure Policy and secure transport configuration, often appearing as a paired requirement in scenario-based questions. A common trap is to set only one property, leaving the other at its default—for example, enabling HTTPS but forgetting to restrict the TLS version, which still allows TLS 1.0 or 1.1. Remember the mnemonic “HTTPS first, then TLS last” to recall that you must enforce the protocol before locking the encryption version.
SC-100 Practice Question: Design solutions that align with security best practices and priorities
This SC-100 practice question tests your understanding of design solutions that align with security best practices and priorities. 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.
Refer to the exhibit. You are reviewing an ARM template for a storage account. The security team has mandated that all storage accounts must enforce HTTPS traffic and use TLS 1.2 or higher. Which two changes must be made to the template to comply? (Choose two.)
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Change 'minimumTlsVersion' to 'TLS1_2'
Option A is correct because setting 'minimumTlsVersion' to 'TLS1_2' explicitly enforces that only TLS 1.2 or higher is accepted for HTTPS connections to the storage account, meeting the security mandate. Option E is correct because setting 'supportsHttpsTrafficOnly' to true ensures that all traffic to the storage account must use HTTPS, blocking any HTTP requests and aligning with the requirement to enforce HTTPS traffic.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
Microsoft often tests the misconception that network access controls (like network ACLs) or storage account type changes can enforce encryption or TLS version requirements, when in fact only the explicit 'minimumTlsVersion' and 'supportsHttpsTrafficOnly' properties control these security settings.
Detailed technical explanation
How to think about this question
The 'minimumTlsVersion' property in Azure Storage accounts accepts values like 'TLS1_0', 'TLS1_1', or 'TLS1_2', and setting it to 'TLS1_2' rejects all connections using older TLS versions at the transport layer, enforced by Azure's front-end gateways. The 'supportsHttpsTrafficOnly' property (also known as 'enableHttpsTrafficOnly') redirects HTTP requests to HTTPS or rejects them, ensuring data in transit is encrypted; this is critical for compliance with standards like PCI DSS or HIPAA that mandate encrypted channels.

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.

What is the correct answer to this question?
The correct answer is: Change 'minimumTlsVersion' to 'TLS1_2' — Option A is correct because setting 'minimumTlsVersion' to 'TLS1_2' explicitly enforces that only TLS 1.2 or higher is accepted for HTTPS connections to the storage account, meeting the security mandate. Option E is correct because setting 'supportsHttpsTrafficOnly' to true ensures that all traffic to the storage account must use HTTPS, blocking any HTTP requests and aligning with the requirement to enforce HTTPS traffic.

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. Refer to the exhibit. You are reviewing an ARM template for an Azure storage account. Which security best practice is implemented?
medium
A.Enforce HTTPS traffic only
B.Restrict network access by IP address
✓ C.Deny all network traffic by default
D.Enable soft delete for blobs
Why C: The template sets supportsHttpsTrafficOnly to true (enforces HTTPS) and minimumTlsVersion to TLS1_2 (requires TLS 1.2). It also sets networkAcls defaultAction to Deny (denies all traffic by default). All these are security best practices. However, the question asks for which practice is implemented; the most notable is the network ACL default deny. The answer could also be enforcing HTTPS. But typical exam focuses on network access restriction.
