SC-900 Practice Question: Describe the concepts of security, compliance, and identity
This SC-900 practice question tests your understanding of describe the concepts of security, compliance, and identity. 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.
Your organization uses Microsoft Sentinel as a SIEM. You need to create a rule that triggers an incident when a user account is created in an Azure subscription and then logs in from an unfamiliar location within 24 hours. Which type of rule should you configure?
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
✓
Scheduled query rule
A scheduled query rule is the correct choice because it allows you to define a KQL query that detects user account creation events (e.g., from AzureActivity) and then correlates those with sign-in logs (e.g., from SigninLogs) from unfamiliar locations within a 24-hour window. This rule type supports complex multi-table joins and time-based correlation, which is exactly what the scenario requires.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Why it's wrong here

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse scheduled query rules with near-real-time (NRT) rules, mistakenly thinking NRT rules can handle long correlation windows, but NRT rules are limited to a 10-minute lookback and cannot span 24 hours.
Detailed technical explanation
How to think about this question
Under the hood, a scheduled query rule runs a KQL query at a defined interval (e.g., every 5 minutes) over a specified lookback period (e.g., 24 hours). The query can use the `join` operator to link `AzureActivity` (for account creation) with `SigninLogs` (for login from unfamiliar location), and the `where` clause can filter by `TimeGenerated` to enforce the 24-hour window. A real-world scenario might involve an attacker creating a backdoor account and then using it from a new IP; the rule must correlate these two distinct log sources with precise timestamp logic.
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 cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
