In Kerberos, the Ticket-Granting Ticket (TGT) is the feature that enables single sign-on (SSO). After initial authentication, the user receives a TGT from the Key Distribution Center (KDC). The TGT is then used to obtain service tickets for accessing various resources without re-authenticating, providing a seamless SSO experience. Sign in with Apple at Work & School (option A) is an Apple-specific feature, not a Kerberos component. OAuth (option B) and SAML (option D) are separate SSO protocols, not Kerberos features. TheApple Platform Security Guideexplains the TGT’s role in Kerberos SSO.

Content caching on a Mac (macOS 10.13 or later) doesn’t require an Apple ID, Managed Apple ID, or Personal Apple ID to function. It’s a system-level feature enabled in macOS settings or via MDM, caching content like app updates and iCloud data for network efficiency. While iCloud caching benefits from a user’s Apple ID on client devices, the caching Mac itself doesn’t need one. The Apple Platform Deployment Guide confirms no Apple ID is required for content caching setup.

Configuration profiles allow IT administrators to manage firewall settings on macOS devices, enabling or disabling the firewall, specifying allowed apps, or configuring stealth mode. These profiles are deployed via MDM or manually, ensuring network security. Find My (option B) and iCloud (option C) are unrelated to firewall management. MDM (option D) delivers profiles, but the profiles contain the settings. Note: iOS/iPadOS devices don’t have user-configurable firewalls, so this applies to macOS. TheApple Platform Deployment Guidedetails firewall configuration via profiles.

Declarative Device Management (DDM) modernizes MDM by allowing devices to proactively report state changes and apply configurations autonomously. Apple Learning materials specify that DDM revolves arounddeclarations— structured sets of data that describe desired management states. Among the types of declarations,Activationsare critical. Activations define which configurations or policies are applied under certain conditions, such as enforcing a passcode policy or requiring OS updates. Devices then self-manage against these declarations and report compliance back to the MDM. Other terms like “Devices” or “Enrollments” describe concepts within MDM but are not types of declarations. “Security” is a policy outcome, not a declaration type. Therefore, the correct declaration type as described in Apple’s DDM model isActivations.

Configuration profiles, deployed via MDM or manually, allow IT administrators to restrict apps on a device by setting policies such as blocking the App Store, preventing app removal, or allowing only specific apps (e.g., via an allow list). These profiles are highly customizable for security and compliance. Activation Lock (option A) secures device reactivation, not app restrictions. Find My (option C) and iCloud (option D) are user-focused features without app restriction capabilities. TheApple Platform Deployment Guidedetails configuration profiles’ role in app management.

Apple’s MDM architecture only allowsone enrollment profileper managed device. Apple Learning makes clear that a device can be managed by only one MDM server at a time. This enrollment profile defines the server connection, authentication, and management relationship. Attempting to install another enrollment profile overwrites the existing one, ensuring there is no conflict or dual management. While devices may have multiple configuration profiles for settings, restrictions, or certificates, the enrollment profile itself is unique. This ensures clear accountability and prevents devices from being subject to conflicting MDM commands. Options suggesting two or three enrollment profiles, or unlimited enrollment, do not align with Apple’s management model.

Apple Configurator for Mac resolves boot issues. TheApple Configurator User Guidestates, "If an iPad is stuck on the Apple logo, connect it to a Mac running Apple Configurator to perform a full restore." Option A doesn’t exist, and B and C don’t address this issue directly.
