Question 882 of 975

Manage security and threats by using Microsoft Defender XDR →hardMultiple ChoiceObjective-mapped

Quick Answer

The answer is to configure Microsoft Defender XDR by enabling Defender for Office 365 with anti-phish and impersonation protection, Defender for Identity, and Defender for Endpoint with automated investigation and response. This comprehensive defense strategy against ransomware with Microsoft Defender XDR directly meets all four requirements: Defender for Office 365 prevents phishing from reaching executives, Defender for Identity detects lateral movement from compromised credentials, Defender for Endpoint automatically contains compromised devices, and the unified XDR portal provides a single incident view across email, endpoints, and identities—all with minimal manual effort. On the MS-102 exam, this question tests your understanding of how Microsoft’s integrated security stack works together rather than relying on standalone tools like Sentinel or Purview. A common trap is choosing Microsoft Sentinel because it offers SIEM capabilities, but it lacks the native prevention and automated containment that Defender XDR provides out of the box. Memory tip: think “XDR = Office + Identity + Endpoint” to cover the three attack stages: phishing, lateral movement, and ransomware deployment.

MS-102 Practice Question: Manage security and threats by using Microsoft Defender XDR

This MS-102 practice question tests your understanding of manage security and threats by using microsoft defender xdr. 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.

You are a security administrator for a large enterprise with 10,000 users. The company uses Microsoft 365 E5 licenses, which include Microsoft Defender XDR. The company has recently experienced a series of ransomware attacks where attackers gained initial access through phishing emails, then moved laterally using compromised credentials, and finally deployed ransomware on file servers. The CISO wants to implement a comprehensive defense strategy that reduces the attack surface and automates response. The requirements are: 1) Prevent phishing emails from reaching users, especially those targeting executives. 2) Detect and block lateral movement using compromised credentials. 3) Automatically contain compromised devices during an incident. 4) Provide a unified incident view across email, endpoints, and identities. You need to recommend a solution that meets all requirements with minimal manual effort. What should you do?

A
Configure Microsoft Defender XDR by enabling Defender for Office 365 with anti-phish and impersonation protection, Defender for Identity, and Defender for Endpoint with automated investigation and response.
Defender XDR meets all requirements: anti-phish, lateral movement detection, automatic containment, unified incident view.
B
Use Microsoft Purview to classify and protect sensitive data, and configure data loss prevention policies to block ransomware.
Why wrong: Purview is for data protection, not for detecting lateral movement or containing devices.
C
Deploy Microsoft Sentinel and create analytics rules to detect phishing, lateral movement, and ransomware. Configure automated playbooks to contain devices.
Why wrong: Microsoft Sentinel alone does not prevent phishing or automatically contain devices; it requires integration.
D
Upgrade to Microsoft Entra ID P2 and enable Identity Protection for risky sign-ins and user risk. Use Conditional Access to block access from compromised devices.
Why wrong: Entra ID P2 provides identity protection but does not cover email or endpoint containment.

Why each option matters

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.

Correct answer & explanation

✓

Configure Microsoft Defender XDR by enabling Defender for Office 365 with anti-phish and impersonation protection, Defender for Identity, and Defender for Endpoint with automated investigation and response.

Option A is correct because Microsoft Defender XDR integrates Defender for Office 365 (for anti-phish with impersonation protection), Defender for Identity (for detecting lateral movement), Defender for Endpoint (for automatic containment), and provides a unified incident view. Option B is wrong because Microsoft Sentinel alone does not include all the required protections. Option C is wrong because Microsoft Purview is for compliance, not security. Option D is wrong because Microsoft Entra ID P2 lacks endpoint and email protection.

Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.

✓
Configure Microsoft Defender XDR by enabling Defender for Office 365 with anti-phish and impersonation protection, Defender for Identity, and Defender for Endpoint with automated investigation and response.
Why this is correct
Defender XDR meets all requirements: anti-phish, lateral movement detection, automatic containment, unified incident view.
Related concept
Static NAT maps one inside address to one outside address.

Common exam traps

Common exam trap: NAT rules depend on direction and matching traffic

NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.

Detailed technical explanation

How to think about this question

NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.

KKey Concepts to Remember

Static NAT maps one inside address to one outside address.
PAT allows many inside hosts to share one public address using ports.
Inside local and inside global describe the private and translated addresses.
NAT ACLs identify traffic for translation, not always security filtering.

TExam Day Tips

Identify inside and outside interfaces first.
Check whether the scenario needs static NAT, dynamic NAT or PAT.
Do not confuse NAT matching ACLs with normal packet-filtering intent.

Key takeaway

NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.

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.

What to study next

Got this wrong? Here's your next step.

Review the four NAT address types (inside local, inside global, outside local, outside global), PAT port overload, and static vs dynamic NAT use cases. Then practise related MS-102 NAT questions on configuration and troubleshooting.
