The correct answer is to create an alert suppression rule scoped to the test VM and alert type. This is the precise mechanism in Microsoft Defender for Cloud that allows you to dismiss valid but non-actionable alerts for known resources, such as a test VM used by the security team, without reducing detection coverage for other assets. The rule is configured at the subscription or resource group level and uses conditions like resource ID and alert name to automatically suppress matching alerts, effectively reducing alert noise while preserving visibility into real threats. On the SC-200 exam, this scenario tests your understanding of how to balance security monitoring with operational efficiency—a common trap is confusing suppression rules with automation rules or modifying alert severity, which would not solve the noise problem for a specific resource. Remember the key distinction: suppression rules are for *dismissing* alerts you already know are safe, not for changing how they are generated. A helpful memory tip is "Suppress the specific, not the generic"—scope your rule tightly to the test VM and the exact alert type to avoid accidentally hiding true positives elsewhere.
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 Defender for Cloud alert repeatedly fires for a known test VM used by the security team. The alert type is valid, but it should not create noise for that VM. What should the analyst 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 alert suppression rule scoped to the test VM and alert type.
Option A is correct because an alert suppression rule in Microsoft Defender for Cloud allows you to define a scope (e.g., a specific VM) and a condition (e.g., a specific alert type) to automatically dismiss alerts that are valid but not actionable for that resource. This reduces noise without affecting detection coverage for other resources. The rule is configured at the subscription or resource group level and applies only to matching alerts.
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.
✓
Create an alert suppression rule scoped to the test VM and alert type.
Why this is correct
This suppresses known benign noise without disabling protection globally.
Related concept
Read the scenario before looking for a memorised answer.
✗
Disable Defender for Servers for the entire subscription.
Why it's wrong here
That would reduce protection for unrelated production resources.
✗
Change the VM name.
Why it's wrong here
Renaming the VM does not address alert generation.
✗
Delete the recommendation from secure score.
Why it's wrong here
Recommendations cannot be deleted as a noise-control method.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates may confuse alert suppression (which dismisses alerts without affecting detection) with disabling a security plan or modifying secure score, leading them to choose overly broad or irrelevant actions like disabling Defender for Servers or deleting recommendations.
Detailed technical explanation
How to think about this question
Alert suppression rules in Defender for Cloud are evaluated at the time of alert generation; they use Azure Resource Graph to match the alert's scope (e.g., resource ID) and properties (e.g., alert type) against the suppression rule's conditions. Once matched, the alert is automatically dismissed and not stored in the security alerts list, but it is still logged in the Azure Activity Log for auditing. This is distinct from disabling a plan, which removes the underlying sensor or agent, or modifying a recommendation, which only affects the secure score calculation.

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
An e-commerce site experiences heavy traffic on Black Friday and near-zero traffic during off-peak weeks. Rather than provisioning permanent large VMs, the team uses auto-scaling groups that add capacity automatically under load and reduce it overnight. Questions like this test whether you understand elasticity, availability zones, and cloud compute scaling patterns.
