Which PowerShell cmdlet should you run?

You need to troubleshoot the issue with SRV2.

Which PowerShell cmdlet should you run?
A . Confirm-MsolDomain
B . Get-MsolDomamFederationSettings
C . Get-MsolDomamVerificationDns
D . Get-MsolServicePrincipalCredential
E . Get-Mousers

Answer: D

Explanation:

To troubleshoot the issue with SRV2, you need to run the Get-MsolServicePrincipalCredential PowerShell cmdlet, which returns the credentials that are associated with a service principal in Azure AD. The service principal is an identity that represents an application or a service that interacts with Azure AD. In this case, the service principal is used by the NPS extension for Azure AD MFA to communicate with Azure AD and perform MFA requests. The credentials of the service principal include a certificate and a key that are used to authenticate the service principal to Azure AD. If the credentials are expired or invalid, the MFA requests will fail with a security token error. To resolve this issue, you need to renew the credentials of the service principal by using the New-MsolServicePrincipalCredential cmdlet.
