Which two events trigger a CoA for an endpoint when CoA is enabled globally for ReAuth? (Choose two.)

The correct answer is C. endpoint profile transition from Apple-device to Apple-iPhone D. endpoint profile transition from Unknown to Windows 10-Workstation. When Change of Authorization (CoA) is globally enabled for reauthentication in Cisco ISE, an endpoint's profile transitioning to a more specific or different classification triggers a CoA.

Why each option

When Change of Authorization (CoA) is globally enabled for reauthentication in Cisco ISE, an endpoint's profile transitioning to a more specific or different classification triggers a CoA.

Aendpoint marked as lost in My Devices Portal

Marking an endpoint as lost in My Devices Portal might trigger other administrative actions like quarantine, but it does not directly trigger a CoA for reauthentication based on a profile change.

Baddition of endpoint to My Devices Portal

Adding an endpoint to My Devices Portal is an administrative action and does not, by itself, trigger a CoA for reauthentication unless it also causes a profile change or policy re-evaluation.

Cendpoint profile transition from Apple-device to Apple-iPhoneCorrect

When an endpoint's profile transitions to a more specific or different profile, such as from a general 'Apple-device' to 'Apple-iPhone', Cisco ISE can initiate a CoA to re-evaluate authorization based on the new, more precise profile.

Dendpoint profile transition from Unknown to Windows 10-WorkstationCorrect

A profile transition from an 'Unknown' status to a clearly identified device type like 'Windows 10-Workstation' signifies a change in endpoint classification, prompting a CoA for reauthentication and reauthorization based on its new identity.

Eupdating of endpoint dACL.

Updating of an endpoint's dACL (Dynamic Access Control List) is typically a *result* of a policy change and subsequent CoA, not an event that *triggers* the CoA for reauthentication itself.
