Conditional Access MFA Exclude Trusted Location
Contoso uses Microsoft Entra ID P1 licenses and has a dedicated corporate office with static public IP addresses. The company wants to require MFA for all users, but exempt users when they connect from the corporate office. Which configuration should the administrator implement?
Quick Answer
The correct answer is to create a Conditional Access policy that targets all users, requires MFA as a grant control, and excludes the corporate office location from the policy. This works because Microsoft Entra ID P1 supports named locations based on static public IP ranges, allowing you to define the corporate office as a trusted location. When a user connects from that IP range, the policy’s exclusion rule triggers, bypassing the MFA requirement while still enforcing it for all other connections. On the MS-102 exam, this scenario tests your understanding of how Conditional Access evaluates policy components in order: exclusions are processed before grant controls, so a trusted location exclusion effectively exempts users without needing separate policies. A common trap is assuming you can simply disable MFA for a location, but Conditional Access requires explicit exclusion logic. Memory tip: think “Exclude the exception” — if you want to skip MFA for the office, exclude that named location from the policy that demands MFA.
⚠ Common exam trap
A common mix-up: candidates confuse 'include' and 'exclude' in Conditional Access conditions, mistakenly thinking that including the office location will exempt it, when in fact excluding the location is required to bypass MFA for that trusted network.

Correct answer & explanation
✓
Create a Conditional Access policy that targets all users, grant access requiring MFA, and exclude the corporate office location from the policy.
A Conditional Access policy can target all users, require MFA as a grant control, and exclude the corporate office location (defined by static public IP addresses as a named location). This ensures MFA is enforced for all connections except those originating from the trusted corporate network, aligning with the requirement to exempt users at the office.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Create a Conditional Access policy that targets all users, grant access requiring MFA, and include the corporate office location as a condition.
Why it's wrong here
Including the corporate office as a condition within a policy that grants MFA does not exempt it; the location condition would still trigger the MFA grant for office traffic. It tempts because location conditions are the standard way to scope Conditional Access, but exemption requires the office to be excluded from the policy's user or location scope.
- ✓
Create a Conditional Access policy that targets all users, grant access requiring MFA, and exclude the corporate office location from the policy.
Why this is correct
Conditional Access evaluates sign-in context, so targeting all users with an MFA grant control and excluding the named corporate location satisfies the requirement. The static public IP defines the trusted location, letting office connections bypass MFA while all other sign-ins still require it.
- ✗
Configure a Per-User MFA policy and add the corporate office IPs to a list of trusted IPs in the MFA settings.
Why it's wrong here
Per-user MFA with trusted IPs is legacy and does not satisfy Conditional Access enforcement; trusted IPs bypass MFA entirely rather than exempting only office traffic under a policy. It tempts because trusted IPs historically exempted office ranges, but Microsoft now recommends named locations with Conditional Access instead.
- ✗
Create a Conditional Access policy that targets the corporate office location and grant access with MFA for all other locations.
Why it's wrong here
Targeting the office location and granting MFA elsewhere inverts the requirement: users at the office would be evaluated by the policy, not exempted, and the grant applies to the wrong scope. It tempts because location-scoped policies are common, but the correct design excludes the trusted location rather than targeting it.

Same concept, more angles
3 more ways this is tested on MS-102
These questions test the same concept from different angles. Work through them to make sure you can recognise it however the exam phrases it.
Variation 1. An organization uses Microsoft Entra ID P2 licenses. They want to implement a policy that forces users to perform multi-factor authentication (MFA) only when they sign in from an untrusted location. The trusted locations include the corporate office IP range. Which type of policy should they create?
medium- A.Identity Protection user risk policy
- ✓ B.Conditional Access policy
- C.MFA registration policy
- D.Authentication methods policy
Why B: Conditional Access policies in Microsoft Entra ID allow administrators to enforce MFA based on conditions like location. By configuring a policy that targets all users and cloud apps, with a condition excluding trusted IP ranges (corporate office), MFA is only triggered when sign-ins originate from untrusted locations. This is the precise mechanism for location-based MFA enforcement.
Variation 2. An organization with Microsoft Entra ID P2 licenses wants to require multi-factor authentication (MFA) for all users but allow them to register their authentication methods before being forced to use MFA. Which configuration should they implement?
medium- ✓ A.Conditional Access policy with MFA grant and a registration campaign
- B.Security defaults
- C.Per-user MFA
- D.Identity Protection user risk policy
Why A: A Conditional Access policy with an MFA grant control enforces MFA for all users, and a registration campaign (or the combined registration experience) allows users to register their authentication methods before enforcement kicks in. This satisfies both the requirement to require MFA and the requirement to let users register first. Entra ID P2 licensing supports Conditional Access and the registration campaign feature.
Variation 3. An organization uses Microsoft Entra ID P2 licenses. They need to require multi-factor authentication (MFA) for all users accessing a critical financial application, but they must exclude a set of service accounts that are members of the 'Service Accounts' group. Which policy should they create?
medium- ✓ A.Conditional Access policy with a grant block requiring MFA and an exclude assignment for the 'Service Accounts' group.
- B.An Identity Protection user risk policy configured to require MFA for high-risk users.
- C.Per-user MFA enforced on all users, then disabled for the service accounts individually.
- D.Conditional Access sign-in risk policy requiring MFA for risky sign-ins.
Why A: A Conditional Access policy allows you to grant access only when MFA is completed, and you can exclude specific groups like 'Service Accounts' from the policy. This ensures all users except the excluded service accounts are prompted for MFA when accessing the critical financial application. The grant block requiring MFA is the appropriate control for this scenario.
