SC-100 Practice Question: Recommend security best practices and priorities
This SC-100 practice question tests your understanding of recommend security best practices and priorities. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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. A security architect reviews the Azure AD Conditional Access policy JSON. The policy is intended to require MFA for all users accessing Azure management (Microsoft Azure Management app ID 797f4846-ba77-4853-9e6f-4433c3e1d1c5), except for the BreakGlassAdmin account and from trusted locations. However, some users report being prompted for MFA even when connecting from the corporate office (which is marked as a trusted location). What is the most likely cause?

Clue: "most likely"
Why it matters: Probability qualifier — the question wants the most probable cause or outcome, not a guaranteed one. Eliminate low-probability options.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The corporate office location is not correctly defined as a trusted location in Azure AD
Option A is correct because the policy is designed to require MFA for all users accessing Azure management, except for the BreakGlassAdmin account and from trusted locations. If the corporate office location is not correctly defined as a trusted location in Azure AD, the Conditional Access policy will not recognize it as an exception, and users connecting from that location will still be prompted for MFA. This mismatch between the intended trusted location definition and the actual location configuration is the most likely cause of the unexpected MFA prompts.
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 corporate office location is not correctly defined as a trusted location in Azure AD
Why this is correct
If the corporate office IP range is not added to trusted locations, 'AllTrusted' won't exclude it.
Clue confirmation
The clue word "most likely" in the question point toward this answer.

Read the scenario before looking for a memorised answer.
✗
The grant controls operator is set to 'OR' instead of 'AND'
Why it's wrong here
Operator 'OR' is acceptable when only MFA is required.
✗
The policy is in 'Report-only' mode
Why it's wrong here
The state is 'Enabled'.
✗
The policy applies to all cloud apps, not just Azure management
Why it's wrong here
The JSON shows includeApplications with the specific app ID.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often assume the policy logic is flawed (e.g., grant operator or app scope) when the real issue is a misconfiguration in the location definition, which is a common oversight in Conditional Access troubleshooting.

Detailed technical explanation
How to think about this question
Azure AD Conditional Access evaluates location conditions based on named locations, which can be defined by IP ranges (IPv4/IPv6 CIDR) or country/region. If the corporate office IP range is not precisely defined or overlaps with other locations, the policy may fail to match the trusted location condition, causing MFA enforcement. Additionally, the policy uses an 'Include' and 'Exclude' structure—excluding trusted locations requires that the location object be correctly configured and assigned to the policy's conditions; a misconfigured IP range or missing location will result in the exclusion not being applied.

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 company's IT admin needs to give a contractor read-only access to production logs without sharing account credentials. Using role-based access control (RBAC) and temporary scoped permissions — not a permanent shared password — is the correct pattern. Questions like this test whether you can apply least-privilege access across cloud identity services.
