Question #: 34
Topic #: 4
A CMDB Administrator is asked to create a query using CMDB Query Builder that displays all operational CIs belonging to a specific Application Service.
Which steps provide the desired outcome?
A.
Add the Application Service and Configuration Item classes to the canvas.
Configure the relationship between the classes.
Add the Operational Status and Name fields as columns.
Run the query.
B.
Add the Application Service and Configuration Item classes to the canvas.
Configure the relationship between the classes.
Define a filter for the Application Service name and the operational status of the configuration items.
Run the query.
C.
Add the Business Application, Application Service, and Configuration Item classes to the canvas.
Define a filter for the Application Service name and the operational status of the configuration items.
The query must contain the Application Service and Configuration Item nodes, the appropriate relationship between those nodes, and filters that restrict the results to the named Application Service and operational CIs.
Option A only adds Operational Status and Name as result columns. Displaying a field as a column does not filter records according to that field, so non-operational CIs could still appear.
Option C unnecessarily adds the Business Application class. The requirement is to find CIs belonging to a specific Application Service; no Business Application condition or relationship is required. Adding unnecessary classes can complicate the query and potentially alter its results.
CMDB Query Builder is designed to traverse relationships between CMDB classes. The guide similarly explains that Application Services and their related infrastructure should be represented through a CMDB query and connected through CMDB relationships.
Therefore, the correct sequence is Option B.
