The correct configuration is to create an automation rule that runs a playbook when an incident is created. This works because automation rules in Microsoft Sentinel are designed to trigger automated responses—such as executing a playbook—based on incident creation or update events, allowing you to seamlessly block the email sender in Exchange Online via the playbook’s logic. On the Microsoft Cybersecurity Architect exam, this scenario tests your understanding of how automation rules serve as the bridge between incident generation and response actions, a common trap being to confuse them with analytics rules, which create incidents from raw data rather than reacting to existing ones. Remember the memory tip: automation rules are the “trigger,” playbooks are the “action”—think of it as “incident in, playbook out” to avoid mixing up roles.
SC-100 Practice Question: Design security operations, identity, and compliance capabilities
This SC-100 practice question tests your understanding of design security operations, identity, and compliance capabilities. 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 deploys Microsoft Sentinel and wants to automatically respond to phishing emails reported by users. You need to recommend a solution that creates an incident in Sentinel and blocks the email sender in Exchange Online. What should you configure?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Create an automation rule that runs a playbook when an incident is created.
Option A is correct because automation rules in Microsoft Sentinel can trigger playbooks when an incident is created. Option B is wrong because analytics rules create incidents from data, not from existing incidents. Option C is wrong because watchlists are for reference data, not automation. Option D is wrong because UEBA is for user behavior analytics.
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.
✗
Use a watchlist to store known phishing senders.
Why it's wrong here
Watchlists are for correlation and reference, not automatic response.
✓
Create an automation rule that runs a playbook when an incident is created.
Why this is correct
Automation rules trigger playbooks on incident creation, which can then block the sender via Exchange Online actions.
Related concept
Read the scenario before looking for a memorised answer.
✗
Enable UEBA to detect anomalous email behavior.
Why it's wrong here
UEBA identifies anomalies but doesn't provide automated response actions.
✗
Create an analytics rule that queries user-reported phishing data.
Why it's wrong here
Analytics rules create incidents but don't run automated actions on existing incidents.
Common exam traps
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
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.
Use explanations to understand the rule behind the answer.
TExam Day Tips
→Underline the problem statement mentally.
→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.

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. Your organization uses Microsoft Sentinel and wants to automatically respond to high-severity incidents. Which feature should you configure?
easy
✓ A.Configure an automation rule to run a playbook automatically
B.Create a playbook and run it manually for each incident
C.Set up an analytics rule with automatic response
D.Use a workbook to trigger a playbook
Why A: Automation rules in Microsoft Sentinel allow you to define automated responses that trigger when an incident is created or updated, including running playbooks (Azure Logic Apps workflows) automatically. This is the correct approach for automatically responding to high-severity incidents because it eliminates manual intervention and ensures consistent, immediate action based on incident properties like severity.
Variation 2. Your organization uses Microsoft Sentinel and wants to automatically respond to high-severity incidents without human intervention. Which feature should you configure?
easy
✓ A.Automation rule
B.Analytics rule
C.Workbook
D.Watchlist
Why A: Automation rules in Microsoft Sentinel allow you to automatically respond to incidents based on criteria such as severity. Option C is correct because automation rules can trigger playbooks. Option A is wrong because analytics rules create alerts, not automated responses. Option B is wrong because workbooks are for visualization. Option D is wrong because watchlists are for correlation.
