ServiceNow CIS-EM free question 3 / 10 · Domain 3: Event Configuration and Use
Event field mappings are stored in one table, and the mapping values that apply to the alert come from another. Which table supplies those mapping values?
- Event [em_event]
- Alert [em_alert]
- Event Field Mapping [em_mapping_rule]
- Event Mapping Pair [em_mapping_pair]
Show the answer and explanation
Answer: D
Why this is correct
The Event field mapping configuration page says that Event Management stores event field mappings in the Event Field Mapping [em_mapping_rule] table, and that the mapping values from the Event Mapping Pair [em_mapping_pair] table apply to the alert.
Why the other options are wrong
"Event Field Mapping [em_mapping_rule]" … This is the table that holds the mapping rules themselves, not the one the page names for the mapping values.
"Event [em_event]" … The Event table holds the incoming events; the page does not name it as the source of mapping values.
"Alert [em_alert]" … The Alert table receives the mapped values; the page does not name it as the source of mapping values.
Key point
Keep the two tables apart: the rule (which field maps to which) and the pairs (which value becomes which value). Both names start with em_mapping_, so read the second half.
