Community Q&A
MS-102 — frequently asked questions
Community-vetted answers to 98 common questions about this exam, each traced back to a specific practice question.
Questions from real practice questions
Each Q&A comes from a specific question — follow the link for the full analysisWhich passwordless method works on Windows, Android, and iOS?
Does the Microsoft Authenticator app support passwordless sign-in on Windows?
No. Passwordless phone sign-in with Microsoft Authenticator is limited to iOS and Android devices, so it cannot serve the Windows devices named in this scenario.
Why can't Windows Hello for Business be used for Android and iOS?
Windows Hello for Business is a device-bound Windows credential that relies on the PC's TPM plus PIN or biometrics, so it is unavailable on Android and iOS.
Enabling Passwordless Sign-in on Workgroup Devices
Why can't I just use the Authenticator app without joining devices?
The Authenticator app works best when paired with a trusted device. Joining or registering the device ensures the system recognizes the hardware, enabling stronger security checks and Conditional Access policies.
Is X.509 certificate authentication better than joining devices?
No. Certificate-based auth is a credential type. To manage and deploy these certificates securely in an enterprise, you typically need the devices to be managed via Intune or joined to Entra ID.
Filtering Secure Score by Department
Why not use Administrative Units to filter Secure Score?
Administrative Units delegate permissions and management scope. They do not provide a filtering interface for viewing or prioritizing Secure Score recommendations.
Do I need to apply the tag manually after creating it?
Yes, you must assign the created tag to specific users or devices before it appears as an available filter option in the Secure Score view.
Microsoft 365 Passwordless Authentication Across Platforms
Why is Windows Hello for Business incorrect?
Windows Hello for Business is only supported on Windows devices and cannot authenticate Android or iOS users.
Is MFA considered passwordless?
Standard MFA often uses passwords plus another factor. Passwordless MFA typically refers to methods like FIDO2 or the Authenticator app push.
Enabling Passwordless Sign-in for Workgroup Devices
Why isn't the Authenticator app enough?
The Authenticator app handles user verification, but passwordless methods like Windows Hello for Business require the device itself to be trusted and registered with Entra ID.
Can workgroup devices use any passwordless method?
Workgroup devices can register for basic MFA, but advanced passwordless features like FIDO2 or Windows Hello for Business require the device to be joined to Entra ID.
How Do You Force a Password Change for Leaked Credentials in Entra ID Protection?
Why is a sign-in risk policy not the answer for leaked credentials?
Sign-in risk evaluates the authentication attempt or session, such as an anonymous IP or atypical travel, not compromised stored credentials. Leaked credentials are user risk, and only a user risk policy applies the 'Require password change' remediation.
Does Password protection or SSPR satisfy the leaked-credential requirement?
No. Password protection only blocks weak or banned passwords, and SSPR merely lets users reset their own password. Neither detects leaked credentials or forces a password change based on risk.
Which components configure a Defender for Cloud Apps log collector?
Why is the receiver type not configured on the log collector?
The receiver type (FTP, FTPS, Syslog UDP/TCP/TLS) is part of the data source definition on the Data sources tab, while the log collector record stores its name, host IP/FQDN, and associated data source(s).
Do I still need to configure a receiver type for syslog upload?
Yes, but you configure it when creating the data source, not when creating the log collector; the question asks specifically about log collector components.
Which Cloud Discovery Report Identifies Most-Used Apps in 30 Days?
Why is the Cloud Discovery executive report not the correct answer?
The executive report provides a broad, scheduled overview for management, while the snapshot report offers focused, date-range-specific detail needed to identify the most-used apps in the last 30 days.
Can I use the Cloud Discovery dashboard instead of generating a snapshot report?
The dashboard shows live data, but generating a snapshot report gives you a shareable, time-bound analysis specifically for the last 30 days, which directly answers the question.
Onboard iOS Devices to Microsoft Defender for Endpoint via Intune
Why isn't 'Download an onboarding package' correct for iOS?
Onboarding packages are scripts/configs for Windows and macOS sensors. iOS uses the Microsoft Defender for Endpoint app from the App Store.
What does 'Add an app' mean in Option D?
It means adding the Microsoft Defender for Endpoint iOS store app in the Intune Admin Center and assigning it to user groups.
What Should You Do First for App1 Access Policy in Defender for Cloud Apps?
Why is configuring an app connector not the first step for an App1 access policy?
App connectors provide API-based activity and file visibility; access policies need real-time session control, which requires Conditional Access App Control instead.
Does registering App1 in Microsoft Entra ID automatically onboard it to Defender for Cloud Apps?
No, Entra ID registration alone is not enough; you must deploy Conditional Access App Control to App1 before creating an access policy.
How Do You Monitor Mailbox Activities in Defender for Cloud Apps?
Why is creating a Microsoft 365 app connector (D) not the correct answer?
The app connector is how MDCA ingests Office 365 activity, but with mailbox audit logging off there is no Exchange mailbox activity for it to surface, so the mailbox setting is the required first step.
Does creating an activity policy (A) monitor user mailbox activities on its own?
No. Activity policies only filter and alert on activity already logged in MDCA, so mailbox audit logging must be enabled before a policy can ever see mailbox events.
How to Configure a Custom Phishing Link in Attack Simulation Training?
Why isn't the tenant landing page (D) the answer?
A landing page controls the web page shown after a user clicks the simulated link; it does not compose the phishing email, its link, or the message branding.
Can I edit a global payload to add a custom phishing link?
No. Global payloads are Microsoft built-in templates that cannot be modified; create a tenant payload when you need a custom link, sender, or company terminology.
Configuring Antivirus with Tamper Protection Enabled
Does enabling troubleshooting mode disable tamper protection permanently?
No, it is a temporary state that can be toggled on or off as needed for troubleshooting or configuration.
Can I use a device group to override tamper protection?
No, device groups manage policy assignments but do not bypass the runtime enforcement of tamper protection on individual endpoints.
Does a Strict Preset Security Policy Meet the Balanced Baseline Goal?
Why is the Strict preset security policy wrong when the goal is protecting against spam, phishing, and malware?
Strict protection does cover those workloads, but it is tuned aggressively for high-value or priority users, not as a balanced baseline. The scenario asks for the baseline profile, which is Standard protection.
What should I apply instead to get a balanced baseline for most users?
Apply the Standard preset security policy, which Microsoft defines as the baseline profile suitable for most users and includes anti-spam, anti-phishing, anti-malware, Safe Links, and Safe Attachments.
Which Portal Assigns the Microsoft Defender for Endpoint Baseline?
Why is the Microsoft Defender portal wrong for assigning the Defender for Endpoint baseline?
The Defender portal is for incidents, alerts and advanced hunting; baseline profiles are created and targeted to device groups as Intune endpoint security profiles.
What licensing is required to use the Defender for Endpoint baseline?
The Microsoft 365 E5 subscription in the scenario already includes Intune and Defender for Endpoint, so both the baseline templates and the Intune admin center are available.
Which Devices Can Endpoint DLP Policies Be Applied To?
Do Endpoint DLP policies support Android and iOS devices?
No. Endpoint DLP applies to onboarded Windows 10 1809+, Windows 11, Windows Server 2019/2022 and macOS only; Android and iOS protection comes from the separate mobile DLP capability using the Defender for Endpoint app.
Is macOS supported by Endpoint DLP even though it is not in the options?
Yes, macOS is a supported Endpoint DLP platform, but since the question lists only Windows 11, Android and iOS, Windows 11 remains the single correct choice.
Least privilege role to review Identity Protection risky users
Why is Reports Reader (D) not sufficient for Azure AD Identity Protection risky users?
Reports Reader can view sign-in and audit reports but does not include the Identity Protection risky users list. Security Reader is the read-only security role for that data, so D is not correct.
Why is Global Administrator (A) not the least-privilege choice?
Global Administrator grants full tenant control and far exceeds the review-only requirement. Security Administrator provides the needed Identity Protection access with fewer privileges.
What Compares Microsoft 365 Security Configurations to Best Practices?
Why is Exposure score (E) not the same as Microsoft Secure Score?
Exposure score rates the attack surface risk of devices and identities in Defender Vulnerability Management. It never compares tenant configuration to Microsoft baselines or produces improvement actions.
Does Microsoft Secure Score cover Defender for Cloud Apps recommendations?
Yes. Secure Score aggregates recommendations across Microsoft 365 services, including Defender for Cloud Apps, so some improvement actions relate to cloud app governance.
Which platform supports Microsoft Authenticator passwordless sign-in for two tenants?
Why is iOS the answer when Android also supports passwordless phone sign-in?
The item was written when multi-account passwordless phone sign-in was documented for iOS only. Android parity came later, which is why some learners call the question obsolete.
Can one Microsoft Authenticator install hold accounts from two Microsoft 365 tenants?
Yes. Each work or school account can be added to the same Authenticator install, and passwordless phone sign-in can be enabled per account on a supported platform.
How to Modify city Attribute for AD-Synced Entra Users?
Why can't I change city for synced users in the Microsoft Entra admin center?
Synced users are mastered on-premises, so Entra attributes such as city are read-only in the cloud and any direct change is overwritten by the next synchronization cycle.
Does Set-ADUser need to run on a domain controller?
No, but the Active Directory PowerShell module must be installed. Option A's domain controller wording is still valid because only on-premises AD is authoritative for the synced city attribute.
Which DNS Record Is Needed to Add a Microsoft 365 Domain?
Why is a TXT record used instead of an NS record when adding fabrikam.com to Microsoft 365?
Microsoft 365 uses a TXT record to prove you own the public domain; NS records delegate DNS authority, which is not required for simple domain verification.
Can a PTR record verify domain ownership for Project1?
No. PTR records provide reverse DNS lookup from IP to hostname and are not used by Microsoft 365 to validate a custom domain.
Which devices support the Defender Update controls endpoint security template?
Why can't the Defender Update controls policy be applied to the other devices in the table?
The template configures Microsoft Defender Antivirus protection update behavior, which is delivered only to supported Windows clients, so any non-Windows entry has no settings to receive.
What does the Defender Update controls template actually configure?
It controls how Defender Antivirus protection updates (security intelligence) are obtained and applied, such as update source, frequency and channels, on managed Windows devices.
Which Source Appears on Microsoft Defender XDR Incidents Page?
Why is Microsoft Sentinel not the correct answer here?
Sentinel only appears on the Incidents page when explicitly connected to Defender XDR; Defender for Identity is a default integrated source in a Microsoft 365 tenant.
Does Microsoft Defender for Cloud show incidents in the Defender XDR portal?
Defender for Cloud can integrate, but it is not a native Microsoft 365 Defender incident source by default, so it is not the expected answer for a standard tenant.
Which DLP Rule Condition Works Across the Policy Locations?
Why can't I use keywords as a DLP condition for the exhibit's locations?
Keywords are not supported in every DLP workload; endpoint DLP and Teams chat do not offer the keyword condition, while sensitive info types are universal across the locations.
Can sensitivity labels be used as a DLP rule condition?
Sensitivity labels are a condition in some workloads like Exchange and SharePoint, but they are not available for all locations in the exhibit, so they are not the correct universal choice.
How to Notify HR Manager When SharePoint Files Are Shared?
Why can't I create the alert from the SharePoint site instead?
SharePoint site alerts are scoped to a single site and usually notify the alert creator about item changes, so they cannot notify an HR manager whenever any department user shares a file or folder.
Which Defender portal policy type handles SharePoint sharing notifications?
Use a Microsoft Defender for Cloud Apps activity policy, which can detect SharePoint and OneDrive sharing events and send an email alert to the manager.
First Step to Deploy an Auto-Labeling Policy for Encrypted Emails?
Why should an auto-labeling policy run in simulation mode before turning it on?
Simulation mode identifies which emails match the sensitive info type and would be encrypted, letting you validate the rule without enforcing encryption prematurely.
What is the difference between simulation mode and turning on the auto-labeling policy?
Simulation mode only reports matches and does not apply encryption; turning the policy on enforces the sensitivity label and encryption on matching emails.
Which DLP Policy Location Enables Endpoint Rule Actions?
Why must DLP1 be applied to Devices instead of OneDrive accounts?
Endpoint rule actions come from the DLP agent on Windows and macOS devices, not from cloud storage. OneDrive accounts only exposes file and sharing conditions for cloud files.
Do On-premises repositories ever enable endpoint rule actions?
No. That location is for the information protection scanner discovering files on file shares, so it never surfaces USB, copy, or network-share endpoint actions.
What Does Semi-Require Approval for Non-Temp Folders Do in Defender XDR?
Why is \windows\ not remediated automatically with the non-temp folders setting?
C:\Windows is a core, non-temporary folder, so only the Full – remediate threats automatically level cleans threats there without approval.
Is \users\*\downloads\* treated as a temporary folder by Defender for Endpoint?
Yes. User download and temp paths count as temporary folders, so a threat there is auto-remediated at the non-temp folders level.
Which Devices Support Endpoint DLP Policies in Microsoft 365 E5?
Why aren't Android and iOS devices covered by Endpoint DLP in an E5 subscription?
Endpoint DLP only onboards Windows 10/11 and macOS devices. Android and iOS protection uses Intune app protection policies and Purview DLP for cloud apps such as Exchange Online, SharePoint and OneDrive.
Does an E5 license alone make Android and iOS Endpoint DLP devices?
No. Licensing enables the DLP service, but device support is defined by the platform list Microsoft publishes for Endpoint DLP, which does not include Android or iOS.
How to Purge Malicious Mail Already Delivered to a Mailbox in Defender?
Why does enhanced filtering not remove malicious mail already in a mailbox?
Enhanced filtering only lets Exchange Online trust the last-hop IP and SPF handling of an on-premises connector so hybrid mail is filtered correctly. It never revisits or deletes messages that were already delivered.
Do I configure ZAP in an anti-malware policy in the Defender portal?
Yes. Malware ZAP is controlled from the anti-malware policy family in the Microsoft Defender portal; spam and phishing ZAP live in the anti-spam policy. Malware ZAP is on by default but can be toggled.
How to block Office applications from creating child processes in Microsoft 365?
Why is an EDR policy not enough to block Office apps from creating child processes?
An EDR policy only onboards Windows 11 devices to Defender for Endpoint and configures investigation, remediation and tamper protection settings. Blocking process creation requires an ASR rule, which is delivered through an attack surface reduction policy.
Can Safe Documents for Office clients clear this Secure Score recommendation?
No. Safe Documents opens untrusted files in Protected View in Defender for Office 365 and has no control over whether Word, Excel or Outlook spawn child processes on the endpoint, so the ASR recommendation stays open.
What Implements Social Engineering Awareness in Defender for Office 365?
Why is Learning hub not the answer for social engineering awareness?
Learning hub only provides security awareness content; it cannot create the password-reset phishing simulation or track users who click the link like attack simulation training does.
What does attack simulation training track after a simulated password-reset email?
It records payload link clicks and can automatically assign or suggest follow-up training to users who interact with the simulated message.
Does a Standard Preset Security Policy Meet a Balanced Baseline Goal?
Does 'balanced baseline protection' really mean the Standard preset security policy?
Yes. Standard is the preconfigured balanced profile in Defender for Office 365 preset security policies; Strict is the more aggressive profile that quarantines more.
Why not choose Strict preset security policy for spam, phishing, and malware?
The scenario asks for a balanced baseline, not maximum protection. Strict delivers stronger, quarantine-heavy settings, exceeding the stated requirement.
Does an Intune EDR Policy Auto-Onboard Devices to Defender for Endpoint?
Why is answering No tempting on this Intune EDR policy question?
Many learners believe automatic onboarding requires the Defender for Endpoint connector in Intune, but an assigned EDR policy also delivers the onboarding configuration to targeted devices.
Does the EDR policy onboard devices that are already enrolled in Intune?
Yes. The policy is assigned to a device group, so existing and newly enrolled Windows devices in that group receive the Defender for Endpoint onboarding settings.
Does Co-management Auto-Onboard Devices to Defender for Endpoint?
Does enabling Intune co-management automatically onboard devices to Defender for Endpoint?
No. Co-management only lets Configuration Manager and Intune manage the same device and workload split; it does not push the Defender for Endpoint onboarding configuration.
What actually onboards Intune-enrolled devices to Defender for Endpoint automatically?
An Endpoint Detection and Response (EDR) policy in Intune, together with the Defender for Endpoint connector, delivers the onboarding configuration when the device enrolls.
Does a Device Configuration Profile Onboard Devices to Defender for Endpoint?
Is a device configuration profile still a valid way to onboard devices to Defender for Endpoint?
Yes. Microsoft's MDM onboarding guidance lists both a custom configuration policy and an EDR policy, so the older custom OMA-URI profile method remains supported.
Why do some learners answer No for this scenario?
They assume only the EDR policy or the Defender for Endpoint connector can onboard devices. The question only requires automatic onboarding at Intune enrollment, which the configuration profile provides.
Which Defender for Cloud Apps Policy Blocks Printing from App1?
Why is a session policy correct instead of an activity policy for blocking printing?
A session policy can enforce real-time controls like block printing inside the proxied App1 session, whereas an activity policy is for detecting or alerting on activities after they occur.
Do OAuth app policy or Cloud Discovery anomaly detection policy fit this scenario?
No. OAuth app policies govern app permissions and consent, while Cloud Discovery anomaly detection policies flag unusual shadow IT usage; neither blocks printing from a Conditional Access App Control session.
How to Track Audited Cloud Discovery Apps in Defender for Cloud Apps?
Why can't a Cloud Discovery snapshot report track which apps were audited?
A snapshot report is a static, point-in-time export of discovery data. It adds no status field to the app itself, so the cloud app catalog cannot later display an audited-apps list from it.
How do custom app tags make audited apps visible in the cloud app catalog?
Tag each app after its audit, for example "Audited", then filter or group the Cloud app catalog or discovered-app queries by that tag to show only the audited apps.
How Long Is Attack Simulation Training Available After the Simulation?
Why is 15 days wrong for attack simulation training availability?
Fifteen days belongs to other simulation fields such as due-date or reminder counts, not to the maximum training availability window, which is 30 days after the simulation ends.
What happens if a user ignores the assigned training within the 30 days?
The training assignment simply expires for that user, so the simulation's failure record stands alone and no further training content is served from that campaign.
Which messages are phishing with anti-phishing threshold 3 applied?
Why does 3 - More aggressive flag Mail2 and not only Mail3 and Mail4?
The more-aggressive level lowers the bar: medium-confidence phishing detections are treated as very high confidence, so a medium-PCL message such as Mail2 is actioned by Policy1 as well.
Does adding User1 under 'Include these users, groups and domains' affect the result?
Yes. That setting enables impersonation protection for User1, so messages that spoof her identity are classified as phishing on top of the PCL-based detections.
How to generate a Defender for Endpoint alert for malicious device activity?
Why is option C wrong if it also uses Advanced hunting?
C is not factually wrong, but D is the better answer because it fully specifies the Microsoft Defender portal and matches Microsoft's documented path for custom detection rules.
Can a DLP policy or alert suppression rule generate the required alert?
No. A Purview DLP policy governs data handling, and an alert suppression rule hides matching alerts; neither creates a new Defender for Endpoint alert for malicious device activity.
Which Role Lets a User Review Risky Users in Entra ID Protection?
Why is Reports Reader not enough to see the risky users list in Entra ID Protection?
Reports Reader only covers usage and sign-in/audit reporting surfaces. It does not include the Identity Protection risk detections permission, so the Risky users blade stays inaccessible.
Would User Administrator give User1 access to Identity Protection risky users?
No. User Administrator manages user objects and group membership but has no permission to read Identity Protection risk data, and it would exceed least privilege for a review task.
Which Defender for Office 365 Policy Quarantines .apk and .appx Attachments?
Why is a Safe Attachments policy wrong when the requirement is about attachments?
Safe Attachments detonates files in a sandbox and acts on malware verdicts or unknown-malware timeouts. It has no list where you can name .apk and .appx, so it cannot satisfy an extension-based quarantine requirement.
Where exactly do I add .apk and .appx in the anti-malware policy?
In the policy's Common attachment types filter, add each extension as a custom file type and set the action to Quarantine. Messages carrying those attachment types are then quarantined for review.
Preventing Malicious File Access in Teams, OneDrive, and SharePoint
Why is configuring Safe Links global settings wrong for preventing malicious file downloads?
Safe Links protects against malicious URLs and time-of-click web traffic across Teams, OneDrive, and SharePoint, but it does not scan or block the files themselves. File blocking is handled by Safe Attachments.
Can an Anti-malware policy in Defender for Office 365 protect files in SharePoint or OneDrive?
No. Anti-malware policies are mail-flow policies applied to inbound email messages and their attachments; they do not cover documents stored in SharePoint, OneDrive, or Teams.
Who Can View Sign-Ins in Microsoft Entra Sign-ins Blade?
Which Microsoft Entra roles can read sign-in logs for every user in the tenant?
Reports Reader, Security Reader, Security Administrator, Global Reader and Global Administrator can read sign-in logs tenant-wide. All other users can read only their own sign-in activity.
Does the User Administrator role allow viewing other users' sign-ins?
No. User Administrator covers user and group management only and grants no sign-in log read permission, so that admin sees just their own sign-ins unless given a reports-capable or custom role.
Does Password Hash Sync Meet the Password Policy Goal?
Why does setting password length in the Default Domain Policy affect Entra ID users?
When password hash synchronization is enabled, on-premises password complexity and length policies override the cloud policies for synchronized users, so the domain policy takes effect in Entra ID.
Can users still sign in to Microsoft 365 if the Active Directory forest is offline?
Yes. Password hash synchronization stores the password hash in Microsoft Entra ID, so cloud authentication succeeds even when the on-premises domain controllers are unavailable.
Entra Cloud Sync Least-Privilege Groups and Roles
Why isn't Domain Admins required to install the Microsoft Entra Cloud Sync agent?
The provisioning agent only needs local administrator rights on the server where it is installed, so Domain Admins is unnecessary and violates least privilege by granting full domain control.
What is the least-privilege Microsoft Entra role for configuring Cloud Sync?
Hybrid Identity Administrator. Microsoft documents that the account used for Cloud Sync configuration needs at least this role; Global Administrator is not required.
Which Portals Create Shared Mailbox and Grant Send As?
Can I create shared mailbox Mbox1 in the Microsoft 365 admin center?
Yes. Use Teams & groups > Shared mailboxes > Add a shared mailbox, then add User1 with Send As from the same delegation settings.
Where do I grant Send As permission for a shared mailbox?
In the Exchange admin center, open the mailbox under Recipients > Mailboxes and configure Send As on the Delegation tab; the Microsoft 365 admin center also offers it.
Which Office Versions and File Types Support Sensitivity Labels?
Do Office 2021 and Office 2024 support sensitivity labels?
Yes. Both perpetual Office versions support built-in sensitivity labels for supported Open XML files; they are not limited to Microsoft 365 Apps.
Why are .doc and .xls not supported for sensitivity labels?
Purview sensitivity labels in Office are applied to Open XML formats; legacy binary .doc and .xls files are not in the supported file-type list, so convert them to .docx or .xlsx.
