ServiceNow CIS-Discovery free question 8 / 10 · Domain 3: Configuration Management Database
A large number of duplicate CIs keeps appearing. What should you suspect first?
- Weak identification rules
- A disabled health dashboard
- Too few MID Servers running
- Too many discovery schedules
Show the answer and explanation
Answer: A
Why this is correct
A large number of duplicate CIs might be due to weak identification rules. If a CI cannot be identified uniquely, the same item is created again as another CI.
Why the other options are wrong
"Too many discovery schedules" … More runs alone do not create duplicates. When identification works, each run updates the same CI.
"Too few MID Servers running" … A shortage of MID Servers slows discovery down. It does not make IRE create a second CI.
"A disabled health dashboard" … A dashboard only shows results. Turning it off does not create duplicates.
Key point
Duplicates are a result, not a cause. Go back to the priorities of the identifier entries and the attributes they use.
