SC-200 Respond to security incidents Practice Question
This SC-200 practice question tests your understanding of respond to security incidents. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. 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 and Microsoft Defender for Cloud. During a security incident involving a compromised Azure VM, which THREE actions are appropriate to contain and investigate the incident?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Use Microsoft Defender for Cloud's Just-in-Time VM access to isolate the VM.
Options A, C, and E are correct because enabling network security group flow logs helps trace lateral movement, isolating the VM in Defender for Cloud stops communication, and creating an automation rule can trigger a playbook for response. Option B is wrong because deleting the VM destroys evidence. Option D is wrong because updating the VM does not contain the incident.
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.
✓
Use Microsoft Defender for Cloud's Just-in-Time VM access to isolate the VM.
Static NAT maps one inside address to one outside address.
✓
Create a Microsoft Sentinel automation rule to trigger a playbook that runs investigation actions.
Why this is correct
Automates response steps.
Related concept
Static NAT maps one inside address to one outside address.
✓
Enable network security group flow logs to capture network traffic.
Why this is correct
Helps in investigation and tracing.
Related concept
Static NAT maps one inside address to one outside address.
✗
Delete the compromised VM to prevent further damage.
Why it's wrong here
Destroys evidence.
✗
Update the VM's operating system to the latest patch.
Why it's wrong here
Does not contain an ongoing incident.
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 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.
