The answer is InitialAccess and LateralMovement. These two tactics are identified in the Microsoft Defender XDR alert because the exhibit explicitly lists them within the alert’s metadata, indicating the attacker’s entry point and subsequent movement across the network. InitialAccess covers techniques used to gain a foothold, such as phishing or exploiting vulnerabilities, while LateralMovement describes methods like remote desktop or pass-the-hash used to pivot through systems. On the SC-900 exam, this question tests your ability to read alert details in Microsoft Defender XDR and map them to the MITRE ATT&CK framework, a key skill for understanding threat protection. A common trap is confusing LateralMovement with Persistence or Exfiltration, but remember that moving between hosts is distinct from maintaining access or stealing data. For a quick memory tip: think “In and Across”—InitialAccess gets them in, LateralMovement spreads them across.
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'.)
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."
}
}
}
```
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 "tactics": ["InitialAccess", "LateralMovement"]. Option A lists both. Option B includes Persistence, not shown. Option C includes PrivilegeEscalation. Option D includes Exfiltration.
Key principle: Authentication proves identity; authorization controls what that identity can do after login. Both must work for full privileged access.

InitialAccess and LateralMovement
Why this is correct
These are the two tactics in the alert.
Related concept
Authentication checks who the user is.
Common exam traps
Common exam trap: authentication is not authorization
Logging in proves the user can authenticate. It does not automatically mean the user is allowed to enter privileged or configuration mode. Watch for AAA authorization, privilege level and command authorization details.
Detailed technical explanation
How to think about this question
This kind of question is testing the difference between identity and permission. A user may successfully log in to a router because authentication is working, but still fail to enter configuration mode because authorization is missing, misconfigured or mapped to a lower privilege level.
KKey Concepts to Remember
Authentication checks who the user is.
Authorization controls what the user is allowed to do after login.
Privilege levels affect access to EXEC and configuration commands.
AAA, TACACS+ and RADIUS can separate login success from command access.
TExam Day Tips
→Do not assume successful login means full administrative access.
→Look for words such as cannot enter configuration mode, privilege level, authorization or command access.
→Separate login problems from permission problems before choosing the answer.
Key takeaway
Authentication proves identity; authorization controls what that identity can do after login. Both must work for full privileged access.
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.
