The correct answer is Just-In-Time (JIT) VM access, because this Defender for Cloud feature enforces network security group rules that allow RDP traffic only from pre-approved IP ranges during a specific time window, blocking any connection from an untrusted public IP and triggering an alert. When a user attempts RDP from an IP outside the trusted list, JIT evaluates the request against the defined policy and denies the traffic, generating a security alert in Defender for Cloud. On the SC-200 exam, this scenario tests your understanding of how JIT reduces attack surface by replacing always-open inbound ports with time-bound, IP-restricted access—a common trap is confusing JIT with adaptive application controls or network security groups alone. Remember the memory tip: JIT = “Just In Time, Just In Trust” — only trusted IPs get temporary access, and everything else triggers an alert.
SC-200 Practice Question: Mitigate threats using Microsoft Defender for Cloud
This SC-200 practice question tests your understanding of mitigate threats using microsoft defender for cloud. 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.
An organization uses Microsoft Defender for Cloud and has enabled enhanced security features. They want to receive alerts when a user attempts to connect to an Azure VM via RDP from a public IP address that is not in a predefined list of trusted IP ranges. Which Defender for Cloud plan or feature provides this capability?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Just-In-Time (JIT) VM access
Just-In-Time (JIT) VM access in Microsoft Defender for Cloud allows you to lock down inbound traffic to Azure VMs, reducing exposure to attacks while providing easy access when needed. When enabled, JIT creates rules in the network security group (NSG) that permit RDP (TCP 3389) or SSH (TCP 22) traffic only from specific IP addresses or ranges that you define, and only during a requested time window. If a user attempts an RDP connection from a public IP not in the trusted list, Defender for Cloud generates an alert, as the traffic is blocked by the JIT policy.
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.
✗
Adaptive network hardening
Why it's wrong here
This feature recommends NSG rules based on traffic patterns but does not generate alerts for unauthorized connection attempts.
✗
Network security groups (NSG) flow logs
Why it's wrong here
NSG flow logs capture network traffic data but do not provide real-time alerting for unauthorized access attempts.
✓
Just-In-Time (JIT) VM access
Why this is correct
JIT allows you to define a list of approved source IPs and ports; any connection attempt from an unapproved IP triggers an alert.

✗
File Integrity Monitoring (FIM)
Why it's wrong here
FIM monitors file and registry changes, not network access attempts.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse Adaptive network hardening (which also adjusts NSG rules) with JIT VM access, but Adaptive network hardening does not enforce a predefined trusted IP list or generate alerts for unauthorized RDP attempts—it only recommends rule changes based on traffic patterns.
Detailed technical explanation
How to think about this question
Under the hood, JIT VM access works by leveraging Azure Policy and NSG rules to create a time-bound, least-privilege access model. When a user requests access, Defender for Cloud temporarily adds an allow rule for their source IP to the NSG, and the rule is automatically removed after the approved duration. A subtle behavior is that JIT can also integrate with Azure Bastion for a fully managed RDP/SSH session, and alerts are generated not only for blocked attempts but also for successful connections that bypass JIT (e.g., if a permanent NSG rule allows RDP).

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 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.
