SC-900 Practice Question: Describe the capabilities of Microsoft security solutions
This SC-900 practice question tests your understanding of describe the capabilities of microsoft security solutions. 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.
Exhibit
Refer to the exhibit.
```json
{
"properties": {
"policyType": "Detection",
"displayName": "Suspicious sign-in after MFA bypass",
"severity": "High",
"tactics": ["InitialAccess", "LateralMovement"],
"alertDetails": {
"description": "A user bypassed MFA and signed in from an unusual location."
}
}
}
```
Refer to the exhibit. A security analyst is reviewing a Microsoft Defender XDR alert. Which two tactics identified are most relevant? (This is a multiple-choice question asking which two tactics are shown, but the format is single answer. We need to adjust: The question asks: 'Which two tactics are identified?' The correct answer is the option listing both 'InitialAccess and LateralMovement'.)

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
InitialAccess and LateralMovement
The exhibit shows a Microsoft Defender XDR alert indicating that an attacker gained initial access (e.g., via a phishing link or compromised credential) and then moved laterally within the network (e.g., using remote desktop or SMB). These two stages correspond directly to the InitialAccess and LateralMovement tactics in the MITRE ATT&CK framework, which are the most relevant based on the alert details.
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 that candidates may confuse LateralMovement with PrivilegeEscalation or Exfiltration, but the alert's focus on moving between systems (not escalating privileges or stealing data) clearly points to InitialAccess and LateralMovement as the two most relevant tactics.
Detailed technical explanation
How to think about this question
In Microsoft Defender XDR, alerts are mapped to MITRE ATT&CK tactics and techniques. InitialAccess often involves techniques like T1566 (Phishing) or T1078 (Valid Accounts), while LateralMovement uses techniques such as T1021 (Remote Services) or T1570 (Lateral Tool Transfer). The alert correlation engine links these stages to provide a unified incident view, enabling analysts to trace the attack chain from entry to spread.
KKey Concepts to Remember
Read the scenario before looking for a memorised answer.
Find the constraint that changes the correct option.
Eliminate answers that are true in general but not in this case.
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.
