SERVICENOW-CIS-DISCOVERY Practice Test 10 — 10 Questions

Question 1

You are deploying a MID Server behind a strict firewall. To ensure the MID Server can communicate with the ServiceNow instance without opening unsolicited inbound ports, which configuration is required?

Choose an answer to begin — your selection is scored in the full session.

Accepted Answer

Ensure the firewall allows outbound HTTPS traffic from the MID Server to the instance.. MID Servers communicate via outbound HTTPS (443) requests to the instance, meaning no inbound ports need to be opened on the firewall.

Answer

Set the MID Server listener port to 8443 on the local firewall.

Answer

Configure the instance to use an inbound static IP for the MID Server.

Answer

Enable the 'Inbound Proxy' setting in the MID Server configuration file.

Question 2

What is the primary role of the Identification and Reconciliation Engine (IRE) in the Discovery process?

Accepted Answer

To ensure data integrity and prevent CI duplication.. The IRE acts as a gatekeeper to ensure that only valid, non-duplicate, and authorized data is written to the CMDB.

Answer

To execute discovery probes on target devices.

Answer

To monitor the status of MID servers.

Answer

To map business services based on traffic data.

Question 3

When a MID Server is part of a cluster, what happens to the ECC queue items if one MID Server goes down?

Accepted Answer

The ECC queue items are re-assigned to other MID Servers in the cluster. If load balancing is configured, the other nodes in the cluster take over the work.

Answer

The ECC queue items are deleted

Answer

The jobs are marked as 'Failed'

Answer

The jobs stay in the queue until the failed server returns

Question 4

If you need to change the priority of a data source for a CI attribute, where do you go?

Accepted Answer

Reconciliation Rules. Reconciliation Rules allow an admin to set the priority (integer value) for each data source for specific attributes.

Answer

Discovery Schedule

Answer

Identification Rules

Answer

Discovery Credentials

Question 5

What is the purpose of the 'Table' attribute in the 'Identification' step?

Accepted Answer

To specify the target CMDB class.. The 'Table' attribute defines which CMDB class the identified CI belongs to.

Answer

To set the CI relationship type.

Answer

To filter the input data.

Answer

To name the variable.

Question 6

Which THREE factors should be considered when planning a MID Server installation?

Accepted Answer

Network access to the instance. When planning a MID Server installation, network access to the instance (B) is essential because the MID Server must be able to reach the ServiceNow instance over the required outbound ports (typically HTTPS/443) to register, receive jobs, and return results. Hardware resource availability (C) must be evaluated because the MID Server host needs sufficient CPU, memory, and disk to run the Java-based MID Server process and handle the discovery/integration workloads assigned to it. Operating system compatibility (D) is also required since the MID Server is only supported on specific OS versions (for example, certain Windows Server and Linux distributions) and must match the supported Java runtime. Database version (A) is not a MID Server installation factor because the MID Server does not host or require a local database, and user browser settings (E) are irrelevant since the MID Server runs as a background service without a browser interface.

Answer

Database version

Answer

User browser settings

Question 7

After an upgrade, several CIs are showing as 'Orphaned'. What does this status imply in the context of CMDB Health?

Accepted Answer

The CI has no relationship to any other CI in the CMDB.. An orphaned CI is a CI that has no relationship to other CIs or that is not correctly linked to the business service topology as defined.

Answer

The CI belongs to a class that is no longer supported.

Answer

The CI was discovered by a decommissioned MID Server.

Answer

The CI has no parent class.

Question 8

A Discovery scan successfully identifies a Linux server, but the 'Operating System' field is not being updated in the CMDB. You have verified that the pattern correctly extracts the OS version. What is the most likely configuration issue?

Accepted Answer

A Reconciliation Rule exists that prevents the 'ServiceNow' data source from updating the 'Operating System' attribute.. Data source reconciliation rules determine which data sources have update authority for specific fields.

Answer

The CI class is marked as 'Read Only' in the CMDB dashboard.

Answer

The Discovery schedule is using the wrong MID server.

Answer

The Linux pattern is not published to the production environment.

Question 9

You need to set up a MID Server on Linux. What is the standard process for installing it?

Accepted Answer

Download, extract, and run the shell script. The standard method involves downloading the MID Server zip file, extracting it, and running the installer script.

Answer

Install via Update Set

Answer

Push an installer via the Discovery tool

Answer

Install via the ServiceNow GUI

Question 10

If Discovery cannot find a pattern for an OS version, what does the system typically do?

Accepted Answer

The discovery process for that device fails or remains incomplete.. If no pattern is found, Discovery may fall back to a classification probe or simply stop discovery for that specific device depending on the configuration.

Answer

It automatically creates a generic Linux CI.

Answer

It creates a dummy CI record.

Answer

It uses the last used pattern.
