Question 300
A post-change operational risk review considers: An organization uses smart cards for workstation access and needs to validate redirection and certificate trust. Which risk MOST DIRECTLY explains the need for the proposed AVD control?
Explanation
Correct Answer
The condition is: An organization uses smart cards for workstation access and needs to validate redirection and certificate trust. The directly related risk is: Enabling one sign-in mechanism without device and directory support can leave the user unable to authenticate to the remote desktop. The corrective control is: Plan supported passwordless or smart-card sign-in and MFA methods alongside Azure Virtual Desktop client and session-host prerequisites. Its test of effectiveness is: A pilot completes both workspace authentication and session sign-in using the chosen approved credential flow. This issue is specific to the observed AVD behavior, not to a separate administration concern.
Incorrect Answers
This option relates to Microsoft Entra Domain Services identity integration under AZ-140 objective group 2.1. It addresses a different failure risk: A managed domain is not an automatic replacement for every on-premises trust, DNS and policy dependency. But the observed requirement is: An organization uses smart cards for workstation access and needs to validate redirection and certificate trust. For the targeted topic (Passwordless authentication, MFA and credential selection), the directly relevant risk is: Enabling one sign-in mechanism without device and directory support can leave the user unable to authenticate to the remote desktop. That other measure may be useful in a separate environment, but does not by itself establish the specific requested outcome. An independent qualified Azure Virtual Desktop expert must adjudicate any plausible overlapping alternatives before release.
This option relates to Conditional Access policies for AVD under AZ-140 objective group 2.1. It addresses a different failure risk: A broad untested Conditional Access policy can lock users out of their feeds or prompt unexpectedly across authentication steps. But the observed requirement is: An organization uses smart cards for workstation access and needs to validate redirection and certificate trust. For the targeted topic (Passwordless authentication, MFA and credential selection), the directly relevant risk is: Enabling one sign-in mechanism without device and directory support can leave the user unable to authenticate to the remote desktop. That other measure may be useful in a separate environment, but does not by itself establish the specific requested outcome. An independent qualified Azure Virtual Desktop expert must adjudicate any plausible overlapping alternatives before release.
This option relates to Microsoft Entra joined hosts and supported identities under AZ-140 objective group 2.1. It addresses a different failure risk: Treating Entra join as identical to AD DS join can break applications or profile shares that need legacy directory and Kerberos prerequisites. But the observed requirement is: An organization uses smart cards for workstation access and needs to validate redirection and certificate trust. For the targeted topic (Passwordless authentication, MFA and credential selection), the directly relevant risk is: Enabling one sign-in mechanism without device and directory support can leave the user unable to authenticate to the remote desktop. That other measure may be useful in a separate environment, but does not by itself establish the specific requested outcome. An independent qualified Azure Virtual Desktop expert must adjudicate any plausible overlapping alternatives before release.
