Full question →mediummultiple choiceObjective-mapped
An organization wants to allow users to sign in to Microsoft 365 using their on-premises Active Directory credentials but does not want to synchronize password hashes to the cloud. They also want to eliminate the need for users to re-enter their credentials when accessing cloud resources from domain-joined devices. Which combination of authentication methods should they implement?
Answer choices
Why each option matters
Good practice is not just finding the correct option. The wrong answers often show the exact trap the exam wants you to fall into.
A
Best answer
Pass-through Authentication (PTA) with Seamless Single Sign-On (SSO)
PTA validates passwords on-premises without storing hashes, and Seamless SSO provides automatic sign-in for domain-joined devices.
B
Distractor review
Federation with Active Directory Federation Services (AD FS)
AD FS also avoids password hash sync and provides SSO, but it requires additional on-premises servers and is more complex to manage than PTA.
C
Distractor review
Password Hash Sync (PHS) with Seamless SSO
PHS synchronizes password hashes to the cloud, which the organization explicitly wants to avoid.
D
Distractor review
Cloud-only authentication with MFA
Cloud-only authentication does not use on-premises Active Directory credentials, so it does not meet the requirement.
Common exam trap
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.
Technical deep dive
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.

Question 1
A company recently added the custom domain 'contoso.com' to their Microsoft 365 tenant. Users report that they cannot receive external email sent to their new domain addresses. The administrator confirmed that the domain status shows 'Active' in the Microsoft 365 admin center. What is the most likely cause of this issue?
Question 2
A company has 500 users across Sales, Marketing, and IT departments. User objects are synced from on-premises Active Directory to Microsoft Entra ID using Azure AD Connect. Each department requires different Microsoft 365 license plans (e.g., Sales needs E3, Marketing needs Business Premium, IT needs E5). The administrator wants to automatically assign the appropriate license based on the department attribute without manual intervention. Which approach should the administrator use?
Question 3
A company has purchased 1000 Microsoft 365 E5 licenses and wants to automatically assign licenses to users based on their department attribute, which is synchronized from on-premises Active Directory. The department attribute is stored in Azure AD. Which automated method should the administrator use to achieve this?
Question 4
A company has just purchased Microsoft 365 Business Standard and added the custom domain 'fabrikam.com' to the tenant. They want to verify domain ownership. Which DNS record type must they add to their DNS provider?
Question 5
A company plans to migrate their email from an on-premises Exchange server to Exchange Online. They want to ensure that during the migration, mail sent to users who have already been migrated is delivered to Exchange Online, while mail for non-migrated users is delivered to on-premises. Which type of domain configuration should they use?
Question 6
A company has registered the custom domain 'contoso.com' and wants to host email for the subdomain 'sales.contoso.com' in Exchange Online. They have already verified the root domain. What additional step is required?
FAQ
Questions learners often ask
What does this MS-102 question test?
Static NAT maps one inside address to one outside address.
What is the correct answer to this question?
The correct answer is: Pass-through Authentication (PTA) with Seamless Single Sign-On (SSO) — Pass-through Authentication (PTA) validates on-premises passwords directly against Active Directory without storing hashes in the cloud. Combined with Seamless Single Sign-On (SSO), users on domain-joined devices are automatically signed in to Microsoft 365 using Kerberos tickets, providing a seamless experience. AD FS also provides SSO but requires additional infrastructure; Password Hash Sync (PHS) stores hashes in the cloud, which contradicts the requirement; cloud-only authentication does not use on-premises AD.
