Try these sample questions to test your ServiceNow CIS-Discovery exam readiness. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1Which ServiceNow component executes Discovery probes against target devices on a customer network?

A.MID Server

B.ECC Queue worker on the instance

C.Pearson VUE proctor agent

D.Discovery sensor on the target host

Explanation: The MID Server is a Java application installed on a customer-managed host that initiates outbound HTTPS to the ServiceNow instance and runs probes against in-network targets. The instance never connects directly to customer infrastructure.

2How does a MID Server communicate with the ServiceNow instance?

A.Inbound TCP 1433 from instance to MID Server

B.Outbound HTTPS over port 443 from MID Server to the instance

C.UDP SNMP trap from instance to MID Server

D.Direct database link via JDBC from instance

Explanation: MID Servers initiate outbound HTTPS (TCP 443) to the customer instance and poll the ECC Queue for work. No inbound ports are opened on the customer network.

3After installing a MID Server, which validation step must be completed before it can run Discovery?

A.Manually validate and configure the MID Server in the instance

B.Restart the application node on the instance

C.Reboot the underlying Linux kernel of the host

D.Re-run the Pattern Designer wizard

Explanation: A new MID Server appears in an Up status but must be explicitly validated by an administrator and granted IP and capability ranges before it will accept Discovery work.

4Which MID Server feature limits which Discovery work a specific MID Server is allowed to handle?

A.MID Server capabilities and IP ranges

B.Schedule windows on the instance

C.Discovery classifier priority

D.ECC Queue purge frequency

Explanation: MID Server capabilities (for example, Cloud, Discovery, ACC) and IP range assignments tell the scheduler which MID Server is eligible to pick up specific work.

5Which MID Server cluster type distributes Discovery load across multiple MID Servers concurrently?

A.Load Balanced cluster

B.Failover cluster

C.Standalone MID Server

D.Cold standby cluster

Explanation: A Load Balanced MID Server cluster spreads work across all members at the same time. Failover clusters keep secondary MIDs idle until the primary fails.

6Which file controls the JVM heap size used by a MID Server?

A.wrapper-override.conf

B.discovery.cfg

C.agent_parameters.xml

D.patterns.json

Explanation: wrapper-override.conf is the supported location to set MID Server JVM parameters such as wrapper.java.maxmemory. Editing wrapper.conf directly is overwritten on upgrades.

7Which MID Server property must be set to true for the MID Server to handle Discovery work?

A.mid.discovery (or the Discovery capability)

B.mid.cmdb_health

C.mid.notify_audio

D.mid.upgrade.suppress

Explanation: Adding the Discovery capability (or enabling the corresponding parameter) marks the MID Server as eligible for Discovery jobs. Without it the scheduler will skip the MID for Discovery work.

8A MID Server shows status Down but the Windows service is running. Which check is most likely to identify the cause?

A.Outbound HTTPS connectivity from the MID host to the instance URL

B.Whether SNMPv3 is enabled on the host

C.Whether the host has a public IP

D.Whether Active Directory replication has finished

Explanation: If the MID service is running but the instance shows it down, the MID cannot reach the instance over HTTPS. Test the URL with a browser or curl from the MID host and check proxy settings.

9Which statement best describes the role of the ECC Queue in Discovery?

A.Asynchronous message queue between the instance and MID Servers

B.Synchronous SOAP API used to commit CIs to the CMDB

C.Storage location for credential cipher keys

D.Replacement for the sys_audit table

Explanation: The External Communication Channel (ECC) Queue is an asynchronous message queue. The instance writes output records to the queue and MID Servers pick them up; results return as input records.

10In ECC Queue terms, what is the difference between an output and an input record?

A.Output is the request to the MID Server; input is the response back to the instance

B.Output is a CI commit; input is a probe definition

C.Output is logged in syslog; input is logged in sys_log

D.There is no functional difference

Explanation: Output records carry probe instructions out to the MID Server. Input records carry the data the MID collected back to the instance for sensor processing.

ServiceNow CIS-Discovery Study Tips from Top Performers

1Spend most of your prep time on MID Server deployment and validation because they appear in nearly every Discovery scenario question.

2Practice building and debugging patterns in Pattern Designer against a real Personal Developer Instance so you can read Discovery Log warnings quickly.

3Memorize the Discovery phases (scan, classify, identify, explore) and what each phase writes to the CMDB or ECC Queue.

4Know which credential type and protocol each target uses (SSH for Linux, WMI/WinRM for Windows, SNMPv3 for network, AWS/Azure/GCP credentials for cloud).

5Study CMDB Health pillars (completeness, correctness, compliance) and how identification and reconciliation rules drive each one.

6Review Agent Client Collector vs agentless trade-offs because hardened-host scenarios are common exam questions.

Frequently Asked Questions

What does the CIS-Discovery exam cover?

The exam tests how to deploy MID Servers, configure Discovery Schedules and credentials, build and debug Discovery patterns, run Cloud Discovery against AWS, Azure, and GCP, deploy Agent Client Collector, and keep CMDB Health high through identification and reconciliation rules.

How many questions are on the exam and how long do I get?

ServiceNow lists approximately 60 questions and a 90-minute time limit for the CIS-Discovery exam. The format is multiple-choice and multiple-select, delivered through Pearson VUE either in a test center or via OnVUE remote proctoring.

What score do I need to pass CIS-Discovery?

ServiceNow does not publish a fixed public passing percentage for CIS-Discovery. Your score is compared with an internal cut score that is not shared and is not always 70%, so plan to study to mastery rather than to a fixed number.

What are the prerequisites?

The current blueprint expects candidates to hold the Certified System Administrator (CSA) and Certified Implementation Specialist - Data Foundations credentials, with hands-on Discovery experience on a Personal Developer Instance or production environment.

How much does the exam cost?

The CIS-Discovery exam fee is approximately $300 USD for the initial attempt. Retake fees and policies follow ServiceNow's mainline retake schedule, with mandatory wait periods between attempts.
