Question 370
Which operational change is most appropriate after the team observes: The security update endpoint is blocked by an outbound filtering rule while the EMS listener remains reachable.
Explanation
Correct Answer
The selected action isolates the problem described rather than changing unrelated controls. Test protection-update service reachability separately from EMS Telemetry and correct the narrow egress rule. Underlying reason: Endpoint protection updates and central configuration delivery may use different external services. Confirm resolution by observing: The endpoint retrieves current approved security updates without widening unrelated outbound access.
Incorrect Answers
This does not directly test the stated failure. It addresses 'A compromised laptop can still access a file server from a second branch subnet.' where quarantine labels must translate into actual consistent access restrictions, not merely dashboard indicators. Here the necessary verification is: The endpoint retrieves current approved security updates without widening unrelated outbound access.
That option would be better suited to the separate incident 'A contractor signs up with an identity that was never authorized for a bulk invitation.' Its supporting principle is enrollment invitations impose scope and authentication conditions separate from agent installation. In this case the key condition is endpoint protection updates and central configuration delivery may use different external services.
Although this option is relevant to 'A local application block is resolved by adding an unrestricted exception that survives the incident.', it would not distinguish the actual incident described. The target is to test protection-update service reachability separately from EMS Telemetry and correct the narrow egress rule. and establish the endpoint retrieves current approved security updates without widening unrelated outbound access.
