Deploy and manage a Microsoft 365 tenant →mediumMultiple ChoiceObjective-mapped

Quick Answer

The primary benefit of setting 'supportsHttpsTrafficOnly' to true in an ARM template is that it enforces secure transfer (HTTPS) for all requests to the storage account. This configuration mandates that every connection uses TLS encryption, which protects data in transit from man-in-the-middle attacks and eavesdropping, making it a fundamental security control for compliance frameworks like PCI-DSS and HIPAA. On the Microsoft 365 Administrator MS-102 exam, this setting often appears in the context of a Microsoft 365 migration project, where storage accounts must meet strict data protection standards. A common trap is confusing this with enabling encryption at rest—remember that supportsHttpsTrafficOnly specifically secures data moving to and from the account, not data stored within it. For a quick memory tip, think "HTTPS only = transit only," reinforcing that the setting locks down the communication channel, not the stored data itself.

MS-102 Deploy and manage a Microsoft 365 tenant Practice Question

This MS-102 practice question tests your understanding of deploy and manage a microsoft 365 tenant.

Answer choices

Why each option matters

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.

Correct answer & explanation

✓

It enforces secure transfer (HTTPS) for all requests to the storage account.

Setting 'supportsHttpsTrafficOnly' to true enforces secure transfer by requiring all requests to the storage account to use HTTPS (TLS). This ensures data in transit is encrypted, protecting against man-in-the-middle attacks and eavesdropping. It is a critical security control for compliance with standards like PCI-DSS and HIPAA.

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.

  • ✓

    It enforces secure transfer (HTTPS) for all requests to the storage account.

    Why this is correct

    This setting blocks HTTP requests, requiring HTTPS.

    Clue confirmation

    The clue word "primary" in the question point toward this answer.

    Related concept

    Read the scenario before looking for a memorised answer.

  • ✗

    It reduces latency by enabling CDN integration.

    Why it's wrong here

    Latency reduction is not related to this setting.

  • ✗

    It enables geo-redundant storage.

    Why it's wrong here

    Geo-redundancy is configured via SKU, not this property.

  • ✗

    It minimizes storage costs by reducing bandwidth usage.

    Why it's wrong here

    HTTPS does not reduce cost; it adds encryption overhead.

Common exam traps

Common exam trap: answer the scenario, not the keyword

The trap here is that candidates may confuse 'supportsHttpsTrafficOnly' with performance or redundancy features, but it is purely a security control for enforcing encrypted transport.

Detailed technical explanation

How to think about this question

Under the hood, this setting maps to the Azure Storage REST API property 'supportsHttpsTrafficOnly', which when true, causes the storage account to reject HTTP requests at the network layer with a 403 (Forbidden) error. The setting can be toggled after deployment, but existing connections using HTTP will be immediately terminated. In a real-world migration, failing to enable this could expose sensitive data during bulk uploads if clients default to HTTP.

KKey Concepts to Remember

  • Read the scenario before looking for a memorised answer.
  • Find the constraint that changes the correct option.
  • Eliminate answers that are true in general but not in this case.

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 startup's cloud architect reviews their monthly bill and notices costs are higher than expected for a long-running batch job. Switching from on-demand instances to Reserved Instances — or using Spot/Preemptible VMs — can reduce compute costs by up to 72 %. Questions like this test whether you understand the tradeoffs between commitment, flexibility, and cost across cloud pricing models.
