SERVICENOW-CIS-DISCOVERY Practice Test 2 — 10 Questions

Question 1

Which of the following is the correct order of operations in a horizontal pattern?

Accepted Answer

Identification, Connection, Extension. The standard flow is Identification, then Connection, then Extension sections.

Answer

Connection, Identification, Extension

Answer

Identification, Extension, Connection

Answer

Extension, Identification, Connection

Question 2

You need to add a new port to be scanned by Discovery. Which record do you update?

Accepted Answer

The IP Service record.. To add a new port to be scanned by Discovery, you update the IP Service record. IP Service records define the ports and protocols that Discovery uses during port scanning. Each IP Service record corresponds to a specific service (e.g., HTTP, SSH) and includes the port number and other attributes.

Answer

The MID Server capabilities.

Answer

The Discovery Schedule.

Answer

The Discovery Classifier.

Question 3

When configuring a Discovery Behavior, what is the primary purpose of defining 'Probes' within the behavior?

Accepted Answer

To control which probes are launched for specific device types.. Probes within a Discovery Behavior define which probes are launched for specific device types. This allows customization of the discovery process for different classes of devices, ensuring appropriate probes are used.

Answer

To define the IP address range.

Answer

To define the credential to be used.

Answer

To define which MID Server to use.

Question 4

What does 'Discovery' in ServiceNow primarily populate?

Accepted Answer

The CMDB.. Discovery in ServiceNow primarily populates the Configuration Management Database (CMDB) by discovering and updating configuration items (CIs) and their relationships. It scans the infrastructure, classifies devices, identifies existing CIs, and populates the CMDB with accurate data.

Answer

The knowledge base.

Answer

The user database.

Answer

The incident table.

Question 5

During the Shazzam phase, Discovery identifies that a port is open. If the port corresponds to a configured classifier but no trigger probe is defined, what is the default behavior?

Accepted Answer

The classification phase initiates, but exploration cannot trigger.. During the Shazzam phase, if a port is open and matches a classifier but no trigger probe is defined, the classification phase will still run (to classify the CI based on the classifier), but exploration cannot be triggered because exploration relies on trigger probes to launch additional probes. Thus, the CI may be classified but not fully explored.

Answer

The CI is ignored, and the scan continues.

Answer

Discovery automatically guesses the OS type.

Answer

The scan for that IP is immediately aborted.

Question 6

You are configuring a Discovery CI identification rule for Linux servers and notice that multiple CIs are being created for the same physical device. Which component should you verify to ensure the Identification Engine correctly links the incoming data to an existing CI?

Accepted Answer

Identification Rule. The Identification Engine uses Identification Rules to compare attributes to determine if a CI exists. If these rules are misconfigured, duplicates occur.

Answer

Discovery Schedule

Answer

Discovery Pattern

Answer

Data Source

Question 7

A new device type is not being discovered correctly. Where should you look to ensure the classification process is prepared to handle it?

Accepted Answer

The Discovery Classifiers table.. The 'Discovery Classifiers' table contains the rules used to identify and classify devices.

Answer

The Credential Alias list.

Answer

The IP Range definitions.

Answer

The MID Server configuration.

Question 8

An administrator wants to ensure that data imported from an external asset system does not overwrite data collected by Discovery. How should this be configured?

Accepted Answer

Configure Reconciliation Rules to grant Discovery higher priority for those attributes.. Reconciliation rules allow you to specify which data sources are authoritative for specific CI attributes.

Answer

Change the CI class to read-only.

Answer

Use an Import Set Transform Map script to check the source.

Answer

Disable the external import integration.

Question 9

You want to exclude specific network devices from being created in the CMDB by Discovery. How do you implement this?

Accepted Answer

Add the devices to a Discovery Exclusion List. Discovery Exclusion lists prevent specific IP ranges or devices from being processed by Discovery.

Answer

Disable the Discovery Schedule

Answer

Modify the MID Server capabilities

Answer

Delete the CI from the CMDB after discovery

Question 10

A Discovery run is successfully finding CIs, but the 'CMDB Health Dashboard' shows 'Staleness' errors. What is the primary cause of staleness in the CMDB?

Accepted Answer

The CI has not been updated by a discovery source within the defined threshold.. Staleness occurs when a CI's 'Last discovered' date is older than the threshold defined in the CMDB Health configuration.

Answer

The discovery credentials have expired.

Answer

The CI record has duplicate attributes.

Answer

The CI is not associated with any Discovery Schedule.
