SC-200 Respond to security incidents Practice Question
This SC-200 practice question tests your understanding of respond to security incidents. 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.
Your organization uses Microsoft Defender for Office 365. A user reports receiving a phishing email that was not blocked by the service. You need to improve detection of similar phishing emails. Which TWO actions should you take? (Choose two.)
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Submit the email to Microsoft for analysis using the Submissions page in Microsoft 365 Defender.
Option A and B are correct. Submitting the email for analysis helps improve detection. Configuring anti-phishing policies for user impersonation protection can block similar emails. Option C is wrong because Safe Links is for URLs, not for detecting phishing emails based on content. Option D is wrong because creating a mailbox rule is a client-side action, not a service-wide improvement. Option E is wrong because Attack Simulation Training educates users but does not improve detection.
Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Create an Attack Simulation Training campaign.
Why it's wrong here
Training educates users but does not improve automated detection.
✗
Enable Safe Links for all users to block malicious URLs.
Why it's wrong here
Safe Links blocks URLs but does not detect phishing emails based on content.
✓
Submit the email to Microsoft for analysis using the Submissions page in Microsoft 365 Defender.
Why this is correct
Submissions help improve the filtering algorithms.
Related concept
Static NAT maps one inside address to one outside address.
✗
Create a mailbox rule to move similar emails to the Junk folder.
Why it's wrong here
Mailbox rules are user-level and do not improve service-wide detection.
✓
Configure an anti-phishing policy to protect against user impersonation.
Why this is correct
Anti-phishing policies can detect and block impersonation attempts.
Related concept
Static NAT maps one inside address to one outside address.
Common exam traps
Common exam trap: NAT rules depend on direction and matching traffic
NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.
Detailed technical explanation
How to think about this question
NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.
KKey Concepts to Remember
Static NAT maps one inside address to one outside address.
PAT allows many inside hosts to share one public address using ports.
Inside local and inside global describe the private and translated addresses.
NAT ACLs identify traffic for translation, not always security filtering.
TExam Day Tips
→Identify inside and outside interfaces first.
→Check whether the scenario needs static NAT, dynamic NAT or PAT.
→Do not confuse NAT matching ACLs with normal packet-filtering intent.
Key takeaway
NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
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. NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
