Question 2

Which Casper diagnostic command is used to force a hardware inventory refresh on a managed device?

Accepted Answer

Question 3

A technician notices that smart card authentication is failing after a Casper enrollment. Which component should be checked first?

Accepted Answer

The device's certificate trust store

Smart card authentication relies on certificate trust chains, so a missing or expired certificate in the trust store is the most common failure point.

Question 4

After a Jamf Pro server upgrade, policies are no longer triggering on check-in. What is the first troubleshooting step?

Accepted Answer

Verify the JSS URL in the device's MDM profile matches the new server address

A server URL mismatch between the device's MDM profile and the upgraded JSS is the most common cause of check-in policy failures post-upgrade.

Question 5

A Casper-managed Mac is showing 'Management Framework Damaged' in Self Service. What corrective action resolves this?

Accepted Answer

Perform a 'sudo jamf removeFramework' followed by re-enrollment

Answer

Removing the damaged management framework and re-enrolling the device restores a clean Jamf management state.
