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?
AA second Active Directory connector for the Litware forest, added on the existing Connect Sync server
BA Connect Sync server in staging mode inside the Litware forest
CMicrosoft Entra Cloud Sync with provisioning agents installed on two Litware servers
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.
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?
APass-through authentication
BFederation with AD FS
CSeamless single sign-on
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.
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.)
AMembers of nested groups inside a pilot group are included in the pilot
BCloud security groups are recommended, to avoid the sync latency of on-premises groups
CA dynamic group can be used so that the pilot grows by department automatically
DEach Staged Rollout feature, such as password hash sync, accepts up to 10 groups
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.
How often does Microsoft Entra Connect Sync run a synchronization cycle by default?
AEvery 2 minutes
BEvery 30 minutes
CEvery 3 hours
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.
Contoso uses seamless single sign-on. How often does Microsoft recommend rolling over the Kerberos decryption key of the AZUREADSSOACC computer account?
ANever; Microsoft Entra ID rotates it automatically
BOnce a year, when the certificate expires
COnly after a domain controller is replaced
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.
Which license does Microsoft Entra Connect Health require?
AMicrosoft Entra ID Free
BMicrosoft Defender for Identity
CMicrosoft Entra ID Governance
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.
What must Contoso do by April 7, 2027 to keep Microsoft Entra Connect Sync working?
AReplace Connect Sync with Cloud Sync, which becomes mandatory for every tenant on that date
BUpgrade to version 2.6.84.0 or later and configure application-based authentication
CMove the Connect Sync database to a full SQL Server instance
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.
