Sample questions

Try each one before opening the answer. Every option is explained, with the Microsoft documentation page that proves it.

Question 1 · choose 1

Contoso syncs its corp.contoso.com forest with Microsoft Entra Connect Sync. It acquires Litware, whose 30,000-user forest has no trust or network path to Contoso's network. Litware users must appear as members in Contoso's tenant with password hash sync, synchronization must survive the loss of a server, and Litware has no SQL Server. What should you deploy?

  1. AA second Active Directory connector for the Litware forest, added on the existing Connect Sync server
  2. BA Connect Sync server in staging mode inside the Litware forest
  3. CMicrosoft Entra Cloud Sync with provisioning agents installed on two Litware servers
  4. DA new tenant for Litware, synchronized into Contoso with cross-tenant synchronization
Show the answer and why
  • AA second Active Directory connector for the Litware forest, added on the existing Connect Sync server

    Incorrect

    Connect Sync doesn't support disconnected forests; the server needs a network path to Litware's domain controllers.

  • BA Connect Sync server in staging mode inside the Litware forest

    Incorrect

    A staging server imports but doesn't export, so it would never create Litware users in the tenant.

  • CMicrosoft Entra Cloud Sync with provisioning agents installed on two Litware servers

    Correct

    Cloud Sync handles disconnected forests with lightweight agents, and several active agents fail over automatically.

  • DA new tenant for Litware, synchronized into Contoso with cross-tenant synchronization

    Incorrect

    Cross-tenant sync creates B2B collaboration users whose passwords stay in Litware's own tenant, and adds a tenant to run.

Cloud Sync's provisioning agents need only outbound connections, support disconnected forests (Connect Sync doesn't) and run as several active agents for automatic failover. Litware's 30,000 users are within Cloud Sync's 150,000-objects-per-domain limit, and password hash sync is supported.

Question 2 · choose 1

Contoso's security policy says Active Directory sign-in hours, disabled accounts and expired passwords must be enforced at the moment a user signs in to Microsoft 365. Contoso wants no federation servers and no perimeter network components. Which sign-in method should you choose?

  1. APass-through authentication
  2. BFederation with AD FS
  3. CSeamless single sign-on
  4. DPassword hash synchronization
Show the answer and why
  • APass-through authentication

    Correct

    Its on-premises agents validate each password against Active Directory, so account states and sign-in hours apply at once.

  • BFederation with AD FS

    Incorrect

    AD FS also enforces these policies but needs the federation servers the company wants to avoid.

  • CSeamless single sign-on

    Incorrect

    Seamless SSO only signs in domain-joined devices silently; it works on top of password hash sync or pass-through authentication.

  • DPassword hash synchronization

    Incorrect

    Password hash sync validates in the cloud and doesn't immediately enforce on-premises account states or sign-in hours.

Pass-through authentication validates passwords on premises through lightweight agents that make outbound connections only, so account expired, disabled, password expired, locked out and sign-in hours are enforced at sign-in. Password hash sync doesn't enforce account state changes until they sync. Enabling password hash sync as well is still recommended for leaked credential detection.

Question 3 · choose 2

Contoso's domain is federated with AD FS. You'll use Staged Rollout to pilot password hash sync with groups of users before converting the domain. Which two statements about the pilot groups are correct? (Choose TWO.)

  1. AMembers of nested groups inside a pilot group are included in the pilot
  2. BCloud security groups are recommended, to avoid the sync latency of on-premises groups
  3. CA dynamic group can be used so that the pilot grows by department automatically
  4. DEach Staged Rollout feature, such as password hash sync, accepts up to 10 groups
  5. EA group that also holds contact objects can be added to Staged Rollout, and the contacts are ignored
Show the answer and why
  • AMembers of nested groups inside a pilot group are included in the pilot

    Incorrect

    Nested groups aren't supported for Staged Rollout.

  • BCloud security groups are recommended, to avoid the sync latency of on-premises groups

    Correct

    The guidance recommends cloud groups for this reason.

  • CA dynamic group can be used so that the pilot grows by department automatically

    Incorrect

    Dynamic groups aren't supported for Staged Rollout.

  • DEach Staged Rollout feature, such as password hash sync, accepts up to 10 groups

    Correct

    The limit is 10 groups each for password hash sync, pass-through authentication and seamless SSO.

  • EA group that also holds contact objects can be added to Staged Rollout, and the contacts are ignored

    Incorrect

    Contact objects inside a group block the group from being added.

Staged Rollout moves selected users to cloud authentication while the domain stays federated. It accepts up to 10 security groups per feature, recommends cloud groups, and doesn't support nested or dynamic groups or groups that contain contacts. The final cutover from federated to managed is still a separate step.

Question 4 · choose 1

How often does Microsoft Entra Connect Sync run a synchronization cycle by default?

  1. AEvery 2 minutes
  2. BEvery 30 minutes
  3. CEvery 3 hours
  4. DOnce a day at midnight
Show the answer and why
  • AEvery 2 minutes

    Incorrect

    Two minutes is Cloud Sync's provisioning interval, not Connect Sync's.

  • BEvery 30 minutes

    Correct

    The built-in scheduler runs a cycle every 30 minutes unless customized.

  • CEvery 3 hours

    Incorrect

    Connect Sync's default is shorter.

  • DOnce a day at midnight

    Incorrect

    Connect Sync's default is shorter; a cycle must run at least every 7 days if you change it.

The Connect Sync scheduler is built into the sync engine and runs a synchronization cycle every 30 minutes by default. CustomizedSyncCycleInterval changes it, and a cycle must still run at least once every 7 days.

Question 5 · choose 1

Contoso uses seamless single sign-on. How often does Microsoft recommend rolling over the Kerberos decryption key of the AZUREADSSOACC computer account?

  1. ANever; Microsoft Entra ID rotates it automatically
  2. BOnce a year, when the certificate expires
  3. COnly after a domain controller is replaced
  4. DAt least every 30 days
Show the answer and why
  • ANever; Microsoft Entra ID rotates it automatically

    Incorrect

    The rollover is a manual step with Update-AzureADSSOForest.

  • BOnce a year, when the certificate expires

    Incorrect

    The recommended interval is much shorter.

  • COnly after a domain controller is replaced

    Incorrect

    Rollover is recommended on a regular schedule, not only after changes.

  • DAt least every 30 days

    Correct

    Microsoft highly recommends rolling over the key at least every 30 days.

Microsoft highly recommends rolling over the seamless SSO Kerberos decryption key at least every 30 days with the Update-AzureADSSOForest cmdlet, running it only once per forest.

Question 6 · choose 1

Which license does Microsoft Entra Connect Health require?

  1. AMicrosoft Entra ID Free
  2. BMicrosoft Defender for Identity
  3. CMicrosoft Entra ID Governance
  4. DMicrosoft Entra ID P1 or P2
Show the answer and why
  • AMicrosoft Entra ID Free

    Incorrect

    Connect Health can't be configured without P1 or P2.

  • BMicrosoft Defender for Identity

    Incorrect

    Defender for Identity is a separate product for threat detection.

  • CMicrosoft Entra ID Governance

    Incorrect

    Governance licenses aren't required for Connect Health.

  • DMicrosoft Entra ID P1 or P2

    Correct

    Connect Health is a feature of Microsoft Entra ID P1 or P2.

Microsoft Entra Connect Health is a feature of Microsoft Entra ID P1 or P2; without one of them, the configuration can't be completed in the admin center.

Question 7 · choose 1

What must Contoso do by April 7, 2027 to keep Microsoft Entra Connect Sync working?

  1. AReplace Connect Sync with Cloud Sync, which becomes mandatory for every tenant on that date
  2. BUpgrade to version 2.6.84.0 or later and configure application-based authentication
  3. CMove the Connect Sync database to a full SQL Server instance
  4. DInstall the MSOnline PowerShell module on the sync server
Show the answer and why
  • AReplace Connect Sync with Cloud Sync, which becomes mandatory for every tenant on that date

    Incorrect

    Supported Connect Sync 2.x versions keep working; migration isn't forced by this date.

  • BUpgrade to version 2.6.84.0 or later and configure application-based authentication

    Correct

    Legacy authentication is retiring, and sync stops after that date without both.

  • CMove the Connect Sync database to a full SQL Server instance

    Incorrect

    The requirement concerns the version and authentication, not the database.

  • DInstall the MSOnline PowerShell module on the sync server

    Incorrect

    Connect Sync replaced its MSOnline calls with Microsoft Graph.

Microsoft requires Microsoft Entra Connect Sync version 2.6.84.0 or later with application-based authentication by April 7, 2027; legacy authentication is retiring and synchronization stops after that date otherwise. Connect Sync 1.x versions no longer work.
