HOTSPOT You have a Microsoft 365 E5 subscription that has a Conditional Access policy named Policy1. You need to perform the following actions: • Create a Conditional Access App Control custom policy named Custom1. • Configure Policy1 to use Custom1. What should you use co create Custom1, and in which settings of Policy1 should you enable Conditional Access App Control? To answer, select the appropriate options in the answer area. NOTE: Each correct selection is worth one point. exhibit

Community Insight

The test is separating the two consoles involved in Conditional Access App Control: the policy object is authored in Defender for Cloud Apps, but the hook that activates it is the Session control inside the Entra Conditional Access policy.

Creating the Custom1 Conditional Access App Control policy requires the Microsoft Defender portal, where Defender for Cloud Apps session policies live, while Policy1 only references it from the Session access controls. This page confirms both hotspot selections and explains why the Entra admin center cannot create the custom policy itself.

Learners try to build Custom1 inside the Entra admin center's Conditional Access blade, because that is where Policy1 is edited; that blade only offers the 'Use Conditional Access App Control' toggle and a link out, it does not author session policies.

Use: Microsoft Defender portal Settings: Session Why: Microsoft Defender portal. Conditional Access App Control is a feature of Microsoft Defender for Cloud Apps, and its session policies are created in the Defender portal (under Cloud apps > Policies > Policy management). The Entra admin center is where you create the Conditional Access policy itself, but the custom App Control policy (Custom1) is a Defender for Cloud Apps session or access policy, so it is built in the Defender portal. Session. In a Conditional Access policy in Microsoft Entra, the Use Conditional Access App Control option sits under Session controls. Selecting it (with "Use custom policy...") redirects matching sessions through the Defender for Cloud Apps reverse proxy, which then enforces Custom1. It is not found under Grant, Conditions, or Target resources.

Defender and Session. You need to create the Policy1 on Entra (Conditional Access), and click "Session" under "Access controls", there is an option "Use Conditional Access App Control" which you can specify Custom1, there is also a hyperlink "Configure custom policy" will redirect you to the MS Defender settings.

When creating a CA policy in entra ID choose session> Use Conditional Access App Control and the following info appears: "Custom policies need to be configured in Cloud App Security portal. This control works instantly for featured apps and can be self onboarded for any app."

ChatGPT says "Microsoft Defender Portal" and "Session" Explanation: To create a Conditional Access App Control custom policy (e.g., Custom1), you must use the Microsoft Defender portal. This is where Cloud App Security (Microsoft Defender for Cloud Apps) policies are configured. In the Conditional Access policy (Policy1), the correct place to enable and reference the App Control policy is within the Session settings. This setting allows session control for things like monitoring, blocking downloads, or applying custom policies through Defender for Cloud Apps.

No, the answer is incorrect. The conditional access app control policies are created in Microsoft Defender for Cloud Apps. You cannot create such policy in the Entra admin center. So create the policy in MS Defender, link it to the CAP from Sessions.

Expert Analysis

Why the Answer Is Correct

Conditional Access App Control is a Defender for Cloud Apps capability, so the custom session policy named Custom1 must be created in the Microsoft Defender portal under Cloud apps > Policies > Policy management. The Entra Conditional Access policy Policy1 never stores the session policy definition; it only contains a Session access control that hands the session to Defender for Cloud Apps and names the custom policy to apply. Selecting Session as the settings location is therefore correct because the 'Use Conditional Access App Control' control, including the custom policy picker and the 'Configure custom policy' hyperlink, lives under Access controls > Session. The two selections together describe the real workflow: author the policy in Defender, reference it from the session control in Entra.

Why Other Candidate Answers Are Wrong

Choosing the Entra admin center (or Microsoft Entra ID > Security > Conditional Access) as the creation location fails because the Conditional Access UI cannot define session policy actions, filters, or content-inspection behavior; it merely delegates. Selecting 'Grant' is wrong because grant controls block or require MFA/compliant device rather than routing a session through a Cloud App Security proxy. Selecting 'Client apps' or 'Conditions' is wrong because those tabs scope when a policy applies, not how a session is controlled after sign-in. Any option implying the policy is stored in Sentinel or Defender for Endpoint misplaces the feature entirely, since App Control is a Defender for Cloud Apps and Entra integration.

Community Comment Notes

As milkfish explained, you build Policy1 in Entra Conditional Access and then click "Session" under Access controls, where the option to use Conditional Access App Control lets you specify Custom1. Optimizor_IT reinforces that the custom policies are created in Microsoft Defender for Cloud Apps and cannot be authored in the Entra admin center, so the policy is made in Defender and then linked from Sessions. Krayzr supplied the Microsoft Learn session-policy article as supporting evidence, and OneplusOne quoted the in-product note that custom policies must be configured in the Cloud App Security portal. Several commenters converged on the same pair of answers, Defender portal plus Session, which matches the product documentation rather than the vote count alone.

Official Reference

Exam Strategy

For any Conditional Access App Control hotspot, first ask which console the artifact lives in: session policies belong to Defender for Cloud Apps, while the reference to them belongs to the Session control of the Conditional Access policy. Remember that 'Grant' and 'Session' are two different access-control groups in the same blade, so do not let the similar wording pull you into the grant controls.

Frequently Asked Questions

Can I create the Custom1 Conditional Access App Control policy directly in the Entra admin center?

No. Entra Conditional Access only hosts the Session control and a 'Configure custom policy' link; the session policy itself must be authored in the Microsoft Defender portal under Cloud apps > Policies.

Which Policy1 setting references the Custom1 session policy?

The Session access controls. Enable 'Use Conditional Access App Control' there and pick Custom1 as the custom policy to apply to the session.
