The answer is Adaptive network hardening. This Microsoft Defender for Cloud feature is the correct choice because it continuously analyzes actual traffic flows, network security group rules, and internet-facing endpoints to identify overly permissive configurations that expose virtual machines to the internet. When such misconfigurations are detected, Adaptive network hardening not only provides actionable recommendations to tighten the rules but also generates security alerts, directly fulfilling the requirement for internet exposure alerts. On the SC-200 exam, this concept tests your understanding of how Defender for Cloud moves beyond static NSG auditing to dynamic, traffic-based risk assessment. A common trap is confusing Adaptive network hardening with just network security group diagnostics or just the secure score recommendations—remember that ANH uniquely combines traffic analysis with alert generation. Memory tip: think “ANH = Alerts + Network Hardening,” where the “A” stands for both “Adaptive” and “Alert” on internet-exposed VMs.
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. 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.
A company wants to be alerted when a virtual machine is exposed to the internet through a permissive network security group rule. Which Microsoft Defender for Cloud feature provides recommendations and alerts for such misconfigurations?
Adaptive network hardening uses machine learning to analyze traffic patterns and recommends NSG rule changes, alerting on internet-exposed VMs due to overly permissive rules.
B
Just-in-time VM access
Why wrong: JIT controls access by opening ports only when needed, but it does not alert about existing permissive rules.
C
File integrity monitoring
Why wrong: FIM monitors changes to registry and files, not network exposure.
D
Application controls
Why wrong: Adaptive application controls create allowlists of running processes, not network exposure.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Adaptive network hardening
Adaptive network hardening (ANH) in Microsoft Defender for Cloud analyzes actual traffic patterns, NSG rules, and internet-facing endpoints to identify overly permissive rules that expose VMs to the internet. It then provides actionable recommendations to tighten those rules and can generate security alerts when such misconfigurations are detected. This directly matches the requirement for alerts on internet exposure via permissive NSG rules.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is confusing a feature that actively controls access (like JIT VM access) with one that detects and alerts on existing misconfigurations (adaptive network hardening), leading candidates to choose JIT because it also deals with internet exposure, but it does not generate alerts for permissive NSG rules.
Detailed technical explanation
How to think about this question
Adaptive network hardening works by collecting flow logs from the Azure Network Watcher and analyzing them against current NSG rules to identify traffic that is allowed but should not be, based on observed legitimate patterns. It then computes a set of hardened rules that restrict access to only known source IPs and ports, and can automatically apply these rules if configured. A real-world scenario is a VM with an NSG rule allowing all inbound traffic on port 3389 (RDP) from the internet; ANH will flag this as a high-severity misconfiguration and recommend restricting it to specific IP ranges observed in legitimate traffic.

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.
