Frequently asked questions

How much does the CIS-Discovery exam cost?

ServiceNow sets exam voucher pricing in ServiceNow University and it can differ by region and by whether you hold a subscription or partner/customer entitlement; check the current price there before booking. Retakes cost less than a first attempt.

How do I keep CIS-Discovery active?

Keep it current with each ServiceNow family release by completing the maintenance (delta) requirement ServiceNow publishes within its window; otherwise the certification lapses.

Do I need networking knowledge?

Yes. Questions assume you understand IP ranges, ports, SNMP, SSH and WMI.

Is it the same as Service Mapping?

No. Discovery finds CIs and relationships; Service Mapping builds application service maps on top of that data.

What is required before the exam?

CSA plus the required Discovery implementation training in ServiceNow University.
