Azure AD Password Protection is the correct solution for a hybrid environment. It allows you to define global and custom banned password lists that are evaluated during password changes for both cloud-only and synchronized users. For synchronized users, the Azure AD Password Protection agent can be installed on-premises to enforce the same policy during on-premises password changes, ensuring consistency. Relying solely on on-premises AD policies (Option A) does not govern cloud-only users. Maintaining separate policies (Option C) creates inconsistency, and user education (Option D) is not enforceable.

Conditional Access is the gatekeeper that enforces the requirement. While device compliance policies define what ‘compliant’ means, a Conditional Access policy is needed to actually block access. You would create a policy targeting users/groups, the relevant cloud app (like Exchange Online or Office 365), and set the grant control to ‘Require device to be marked as compliant.’ App Protection Policies (Option A) manage data at the application level but don’t inherently block access based on *device* compliance. The Company Portal (Option C) is a client app but not the enforcement mechanism. Retiring devices (Option D) is a remediation action, not an access block.

SharePoint Online allows granular external sharing settings per site collection. The most direct solution is to go to the Active sites list in the SharePoint admin center, select the problematic site, and change its external sharing setting (e.g., from ‘Anyone’ to ‘Only people in your organization’). This addresses the immediate need precisely. Changing the org-level setting (Option A) is too broad and affects all sites. A sensitivity label (Option C) protects content but doesn’t directly stop link sharing at the site level. A DLP policy (Option D) can detect and block the action but is more complex to set up than a simple site-level permission change.

The best practice for non-human, automated tasks is to avoid using human user accounts altogether. Azure AD Managed Identities (for Azure resources) or service principals (for apps/services) are designed specifically for this purpose. They provide an identity for the application to use without storing credentials, eliminating the risk of credential leakage and inactive privileged user accounts. Resetting passwords (Option A) still uses a human account. Enforcing MFA (Option B) is not feasible for non-interactive scripts. While removing roles (Option C) reduces risk, it doesn’t provide a modern identity solution for the automation need.

In Microsoft 365, user profile pictures are primarily a user-managed feature. Users can upload their own photos through their profile in Delve, Teams, or Outlook on the web. This is the standard design to empower users and keep photos current. While some organizations use third-party tools or PowerShell scripts to bulk upload photos, the default and most common reason for missing photos is that users haven’t set one. It is not typically a synced attribute from on-premises AD (Option A). Admins can set them via PowerShell but not natively in the admin center (Option B). Meeting policies (Option D) do not control static profile pictures.

Azure AD B2B collaboration is the secure method for working with external partners. It allows you to invite their verified identity as a guest user in your tenant without managing a password for them. You can then assign them a granular Azure RBAC role (like ‘Contributor’ on a specific resource group) following least privilege, rather than giving ‘Owner’ on the entire subscription. This provides accountability (actions are tied to their identity), time-bound access (you can remove the assignment later), and avoids credential sharing. Creating a shared internal account (Option A or C) violates security best practices by breaking non-repudiation and requiring credential management.

The ‘Recording storage’ setting within Teams meeting policies controls where recordings are saved by default. By creating and assigning a policy with ‘Recording storage mode’ set to ‘SharePoint’, you ensure all new meeting recordings are saved to a designated folder in the SharePoint site associated with the Team (for channel meetings) or the organizer’s SharePoint site (for non-channel meetings), not the recorder’s personal OneDrive. This leverages SharePoint’s more granular permission and governance models. Live events policies (Option B) are for a different feature. Conditional Access (Option C) is too broad and disruptive. Disabling the OneDrive folder (Option D) does not redirect the save location.

Update rings in Intune for Windows 10/11 provide granular control over update behavior. By creating a separate update ring assigned to the Finance department (or a group containing their devices), you can set a long ‘Feature update deferral period’ (e.g., 365 days). This allows those devices to continue receiving monthly quality/security updates but pauses the deployment of new feature updates, giving time to test the legacy application’s compatibility. Excluding the group (Option A) would block all updates from that deployment, including security updates. App protection policies (Option C) are for mobile app data management, not OS update control. Deploying a driver (Option D) is a reactive fix, not a preventive control.

Sensitivity labels with encryption are the modern, integrated method for persistent protection. You can create a label that encrypts content and sets permissions (e.g., ‘Do Not Forward’ or custom permissions requiring external user authentication). This label can then be published to users for manual application or, critically, be set to auto-apply based on sensitive information types (like the project code name). The label and its protection travel with the email. While a mail flow rule (Option C) or a DLP policy (Option D) can apply encryption, they typically apply older Rights Management templates and are less granular than the encryption settings available directly in sensitivity labels, which are the recommended approach. Defender for Office 365 (Option A) is for threat protection, not encryption.
