A Network Operations Center includes a group of users who belong to the ObjectServer group, LondonUsers. The organization has a strict requirement to ensure that this group only sees events where the Location field is set to ‘London’ and does not see events from other locations. What is the best way an IBM Tivoli Netcool/OMNIbus administrator might enforce this?

A.
Create a restriction filter (Location = ‘London’) on the ObjectServer and apply it to the group ‘LondonUsers’.

B.
Create a temporal trigger on theObjectServer that contains the following SQL: delete from alerts.status where Location = ‘London’;

C.
Create a master ELV file that has (Location = ‘London’) appended to each monitor box SQL definition and then configure each user’s Native Event List to load this ELV file by default.

D.
Because only Administrators can see Acknowledged events by default, create a temporal trigger on theObjectServer that contains the following SQL: update alerts.status set Acknowledged = 1 where Acknowledged = 0 and Location <> ‘London’;
