Based on the image provided by the user, we can infer that rule 1 and object webserver are locked by another administrator. This is because they have red lock icons next to them, which indicate that they are being edited by another administrator in another session. The lock icons prevent other administrators from modifying these objects until the changes are published or discarded by the original administrator. The lock icons also show the name of the administrator who locked the objects when hovered over with the mouse cursor.
The other options are incorrect because:
Rule 7 was not created by the 'admin' administrator in the current session, but by another administrator in another session. This is because it has a blue lock icon next to it, which indicates that it was added by another administrator in another session. The blue lock icon prevents other administrators from deleting this rule until the changes are published or discarded by the original administrator.
8 changes have not been made by administrators since the last policy installation, but in the current session by the 'admin' administrator. This is because there is a yellow number 8 next to the Install Policy button, which indicates that there are 8 unpublished changes in the current session by the 'admin' administrator. These changes will be published or discarded when the 'admin' administrator clicks on Publish or Discard buttons.
The rules 1, 5 and 6 can be edited by the 'admin' administrator, but only after unlocking them from another administrator who locked them in another session. This is because they have red lock icons next to them, which indicate that they are being edited by another administrator in another session. The 'admin' administrator can unlock these rules by right-clicking on them and selecting Unlock from the menu. However, this will discard the changes made by the original administrator who locked them.
