Administrator Dave logs into R80 Management Server to review and makes some rule changes.

 The padlock sign next to the DNS rule in the Rule Base indicates that another administrator is logged into the Management and currently editing the DNS Rule1. This is a feature of R80 that allows multiple administrators to work on the same policy simultaneously. The padlock sign prevents other administrators from modifying the same rule until the editing administrator publishes or discards the changes2. The other options are not valid explanations for the padlock sign. References: 156-215.80 : Check Point Certified Security Administrator (CCSA R80) : Part 19, Multi-User Policy Editing
