Question 1 · choose 1
Attackers phished Contoso users by sending them codes to enter at the Microsoft device sign-in page. Contoso wants that sign-in method blocked for everyone, except the Android conference room devices on the Meeting-Rooms network location, which sign in that way and must keep working. What should you create?
AA policy for all users that blocks device code flow under Authentication flows, excluding Meeting-Rooms
BA Conditional Access policy that blocks the legacy authentication client apps for all users
CA Conditional Access policy that requires a compliant device for all users, all resources and all client apps
DA token protection session control for all users on Windows devices, excluding Meeting-Rooms
Show the answer and why
AA policy for all users that blocks device code flow under Authentication flows, excluding Meeting-Rooms
Correct
The authentication flows condition targets device code flow, and the location exclusion keeps the rooms working.
BA Conditional Access policy that blocks the legacy authentication client apps for all users
Incorrect
Device code flow is a modern authentication flow, so blocking legacy clients doesn't stop it.
CA Conditional Access policy that requires a compliant device for all users, all resources and all client apps
Incorrect
It doesn't target device code flow and would also stop the conference devices unless they're enrolled.
DA token protection session control for all users on Windows devices, excluding Meeting-Rooms
Incorrect
Token protection binds tokens to devices; it doesn't block device code sign-in.
Conditional Access can target device code flow through the authentication flows condition. Microsoft recommends blocking it wherever possible and allowing it only where needed, for example blocking it everywhere except Android conference room devices in a specific network location.
On devices that aren't compliant, users must reauthenticate every 4 hours and must not stay signed in after closing the browser. An admin created one Conditional Access policy for Office 365 only, with sign-in frequency 4 hours and persistent browser session set to Never persistent, but sessions still persist across browser restarts. What should you change?
AChange the sign-in frequency from 4 hours to Every time
BTurn off Show option to remain signed in on the company branding sign-in page
CTarget All resources in the policy with the persistent browser control
DAdd the Require device to be marked as compliant grant control next to the persistent browser setting
Show the answer and why
AChange the sign-in frequency from 4 hours to Every time
Incorrect
Every time forces reauthentication on each request; persistence across restarts is still the persistent browser control's job.
BTurn off Show option to remain signed in on the company branding sign-in page
Incorrect
The Conditional Access persistent browser setting overrides the branding setting, so this isn't what's failing.
CTarget All resources in the policy with the persistent browser control
Correct
The persistent browser control requires All resources, because every browser tab shares one session token.
DAdd the Require device to be marked as compliant grant control next to the persistent browser setting
Incorrect
That would block or allow access; it doesn't change how long the session lasts.
Persistent browser session is controlled by the authentication session token, which all tabs share, so a policy that sets it must target All resources (formerly All cloud apps). Sign-in frequency can stay app specific. The Conditional Access setting overrides the Stay signed in option in company branding.
Contoso's Mergers SharePoint site must be opened only from compliant devices, while the rest of SharePoint Online keeps its current, lighter requirements. The site's Microsoft 365 group carries a sensitivity label. What should you configure?
AA Conditional Access policy that targets Office 365 SharePoint Online and requires a compliant device
BA protected action in Microsoft Entra ID that maps SharePoint site access to an authentication context
CAn authentication context published to apps, tagged on the site via its label, targeted by a policy
DA Conditional Access policy that requires a compliant device for the members of the labeled site's group
Show the answer and why
AA Conditional Access policy that targets Office 365 SharePoint Online and requires a compliant device
Incorrect
A policy on SharePoint Online applies to every site, not only Mergers.
BA protected action in Microsoft Entra ID that maps SharePoint site access to an authentication context
Incorrect
Protected actions cover Microsoft Entra administrative operations, not opening SharePoint sites.
CAn authentication context published to apps, tagged on the site via its label, targeted by a policy
Correct
Authentication context lets a Conditional Access policy protect specific SharePoint content such as one labeled site.
DA Conditional Access policy that requires a compliant device for the members of the labeled site's group
Incorrect
Targeting the members would apply the requirement to everything they open, not only the Mergers site.
An authentication context is created in Conditional Access and selected as Publish to apps. SharePoint sites can be tagged with it, for example through a sensitivity label, and a Conditional Access policy targeting that context enforces the compliant device requirement only when the tagged content is accessed.
Users on unmanaged devices may read SharePoint Online and Exchange Online content in a browser but must not download, print or sync files. Contoso has no Defender for Cloud Apps license. Which session control should the Conditional Access policy use?
AConditional Access App Control with a session policy that blocks downloads
BSign-in frequency set to one hour for SharePoint on unmanaged devices
CPersistent browser session set to Never persistent
DUse app enforced restrictions, with limited web-only access turned on in SharePoint
Show the answer and why
AConditional Access App Control with a session policy that blocks downloads
Incorrect
App Control proxies sessions through Defender for Cloud Apps, which Contoso doesn't license.
BSign-in frequency set to one hour for SharePoint on unmanaged devices
Incorrect
Shorter sessions still allow downloads, printing and sync.
CPersistent browser session set to Never persistent
Incorrect
Ending the session at browser close doesn't restrict what users do during it.
DUse app enforced restrictions, with limited web-only access turned on in SharePoint
Correct
SharePoint and Exchange read this signal and give unmanaged devices a browser-only experience.
App enforced restrictions pass device information to SharePoint Online and Exchange Online, which then apply their own limited experience, such as web-only access without download, print or sync, on unmanaged devices. SharePoint's limited access setting is turned on alongside the Conditional Access session control.
A security analyst opens Conditional Access insights and reporting to measure a report-only policy, but the workbook shows no data. Which two are prerequisites for the workbook? (Choose TWO.)
ASign-in logs sent to a Log Analytics workspace through a Microsoft Entra diagnostic setting
BSign-in logs archived to an Azure storage account
CAt least the Security Reader role plus permissions on the Log Analytics workspace
DSign-in logs streamed to an Azure event hub for a SIEM
EMicrosoft Entra ID P2 licenses, because report-only results come from ID Protection
Show the answer and why
ASign-in logs sent to a Log Analytics workspace through a Microsoft Entra diagnostic setting
Correct
The workbook queries sign-in data retained in a Log Analytics workspace.
BSign-in logs archived to an Azure storage account
Incorrect
A storage account archives logs; the workbook doesn't query it.
CAt least the Security Reader role plus permissions on the Log Analytics workspace
Correct
Readers need a Microsoft Entra role and access to the workspace to see the workbook.
DSign-in logs streamed to an Azure event hub for a SIEM
Incorrect
Event hubs feed external tools; the workbook doesn't read them.
EMicrosoft Entra ID P2 licenses, because report-only results come from ID Protection
Incorrect
The workbook needs the P1 licenses that Conditional Access needs; report-only results aren't ID Protection data.
Conditional Access insights and reporting is a workbook over sign-in logs kept in a Log Analytics workspace, so a diagnostic setting must send them there. Viewers need at least Security Reader and the matching Log Analytics workspace permissions.
A Conditional Access policy selects Require multifactor authentication and Require device to be marked as compliant, with Require all the selected controls. When is access granted?
AWhen the user completes MFA, whatever the device
BNever, because the two controls conflict
COnly after an admin approves the sign-in
DOnly when both controls are satisfied
Show the answer and why
AWhen the user completes MFA, whatever the device
Incorrect
With Require all the selected controls, the compliant device control must be met as well.
BNever, because the two controls conflict
Incorrect
These controls can be combined.
COnly after an admin approves the sign-in
Incorrect
Grant controls don't involve admin approval.
DOnly when both controls are satisfied
Correct
Require all the selected controls needs every selected control.
Grant controls can be combined with Require all the selected controls or with Require one of the selected controls. With Require all the selected controls, the user must complete MFA and sign in from a device marked as compliant.
An admin must turn security defaults off in a small tenant before creating its first Conditional Access policies. Which role is the least privileged one that can change security defaults?
ASecurity Reader
BAuthentication Administrator
CUser Administrator
DConditional Access Administrator
Show the answer and why
ASecurity Reader
Incorrect
Readers can't change tenant settings.
BAuthentication Administrator
Incorrect
This role manages users' authentication methods, not tenant security defaults.
CUser Administrator
Incorrect
User Administrator manages users and groups, not security defaults.
DConditional Access Administrator
Correct
Configuring security defaults needs at least this role.
Security defaults provide baseline protections for tenants without Conditional Access. Configuring them, including turning them off before using Conditional Access policies, needs at least the Conditional Access Administrator role.
How many authentication context definitions can an organization create in Conditional Access?
A99, identified as c1 to c99
B10
C25
DThere's no limit
Show the answer and why
A99, identified as c1 to c99
Correct
Up to 99 authentication context definitions can be created.
B10
Incorrect
The limit is higher.
C25
Incorrect
The limit is higher.
DThere's no limit
Incorrect
The number is limited to 99.
Authentication contexts are created under Conditional Access > Authentication context. An organization can create up to 99 definitions, c1 to c99, and should keep the set small to limit redirects for users.
