SC-100 Practice Question: Evaluate GRC and security operations strategies
This SC-100 practice question tests your understanding of evaluate grc and security operations strategies. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. 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.
A company is designing a security operations strategy using Microsoft Sentinel. They want to prioritize triage of incidents that involve critical assets. The SOC manager suggests using the entity behavior analytics feature. Which capability of entity behavior analytics helps achieve this goal?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
It profiles entities and assigns an anomaly score based on deviations from baseline behaviors.
Entity behavior analytics (UEBA) in Microsoft Sentinel profiles entities such as users, hosts, or applications by establishing baseline behaviors over time. It then assigns an anomaly score to deviations from that baseline, enabling SOC analysts to prioritize incidents involving critical assets based on unusual activity rather than static rules. This directly supports the goal of triaging incidents by highlighting anomalous behavior on high-value targets.
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 combines multiple alerts into a single incident using Fusion.
Why it's wrong here
Fusion is a correlation engine that reduces alert fatigue, not UEBA.
✗
It uses threat intelligence to correlate with known bad actors.
Why it's wrong here
Threat intelligence correlation is separate; UEBA focuses on behavioral baselines.
✓
It profiles entities and assigns an anomaly score based on deviations from baseline behaviors.
Why this is correct
This is the core of UEBA: creating baselines and scoring anomalies to identify risky entities.

Read the scenario before looking for a memorised answer.
✗
It automatically groups incidents by severity and asset criticality.
Why it's wrong here
This is a basic feature of incident management, not UEBA.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates confuse entity behavior analytics (UEBA) with Fusion or threat intelligence correlation, assuming any 'intelligent' feature must involve combining alerts or external threat data, rather than recognizing that UEBA is specifically about profiling internal entity behavior and scoring anomalies.
Detailed technical explanation
How to think about this question
Under the hood, UEBA in Sentinel uses machine learning models (e.g., time-series decomposition, clustering) to establish behavioral baselines for each entity based on attributes like logon times, data access patterns, or network connections. The anomaly score is calculated using statistical methods such as z-score or percentile ranking, and when a critical asset shows a high anomaly score, it triggers an alert that can be surfaced in the incident queue. In a real-world scenario, a domain controller (critical asset) exhibiting unusual late-night logins from a new IP would receive a high anomaly score, allowing the SOC to triage it before a non-critical workstation with similar behavior.
KKey Concepts to Remember

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.
