ServiceNow CIS-Discovery Exam Questions Instant Access

Question 1

In IT environments, what is the purpose of horizontal discovery?

AA method to map application dependencies

BA way to visualize network traffic

CA strategy for managing user access

DA technique for discovering devices

Answer : A

Question 2

Which choice allows the following functionality to occur?

If this value is set to 1000 and a discovery must scan 10,000 IP addresses using a single MID Server, it creates 10 Shazzam probes with each probe scanning 1000 IP addresses.

AMID Server Clusters

BMID Server selection method

CShazzam Batch Size

DBehaviors

Answer : C

TheShazzam Batch Sizeproperty determines how many IP addresses are scanned by a single Shazzam probe1. If this value is set to 1000 and a discovery must scan 10,000 IP addresses using a single MID Server, it creates 10 Shazzam probes with each probe scanning 1000 IP addresses.This property can be configured in theDiscovery Propertiesmodule underDiscovery Definition2.

Question 3

Which of the following choices must be installed on a MID Server to run Credential-less Discovery?

ACredential-less Extension

BNmap

CAdvanced IP Scanner

DDefender

Answer : B

Credential-less Discovery is a feature of ServiceNow Discovery that allows the instance to identify configuration items (CIs) without using credentials. Credential-less Discovery uses Network Mapper (Nmap), a free and open-source network scanner, to collect information about the CIs by sending packets and analyzing the responses. Nmap must be installed on the MID Server that runs Credential-less Discovery.Credential-less Discovery can be used as a fallback option when credential-based probes fail, or as a primary option for scanning certain types of devices, such as network devices, printers, or IoT devices12.

Question 4

Which of the following are the results of executing the WMI Query?

Choose 3 answers

AA scalar variable named 'PageFaults'.

BA tabular variable named 'more_process_info'.

CA scalar variable named 'PeakVirtualSize'.

DA tabular variable named 'Win32 Process'.

EA scalar variable named 'MaximumWorkingSetSize'.

FA tabular variable named 'WMI Query',

Answer : B, C, E

Question 5

Which choice best describes what happens when, by default, duplicate CIs are detected during identification and reconciliation?

AThe next discovery is stopped for the CI that is duplicated.

BEach set of duplicate CIs is added to a de-duplication task.

CA notification is sent to the CI owner.

DAn association identification rule is created automatically.

Answer : B

Question 6

During the Port Scan phase what could the Warning level error "No results returned from probe." mean?

AProcess Classifier incorrectly configured

BLogical or physical firewall preventing connectivity

CWrong credentials

DIncorrect Datasource Precedence

Answer : B

During the Port Scan phase in ServiceNow Discovery, the warning level error 'No results returned from probe' typically indicates a connectivity issue. This error often arises when a logical or physical firewall is blocking the connectivity between the MID Server and the target device. This prevents the probe from successfully scanning the ports and returning results. The other options, such as incorrect process classifier configuration, wrong credentials, or incorrect datasource precedence, would generally lead to different types of errors or issues in the discovery process. Reference = ServiceNow Discovery documentation, particularly the sections that deal with troubleshooting Port Scan issues and understanding common errors during Discovery phases.

Question 7

One method for deleting specific CIs not discovered in 30 days is:

AScheduled Job

BUI Policy

CService Mapping

DData Policy

Answer : A

One method for deleting specific CIs not discovered in 30 days is to use a scheduled job that runs a script to query the CMDB for CIs that have not been updated by Discovery for a certain period of time, and then delete them or mark them as retired. This method can help you keep your CMDB clean and accurate, and avoid having stale or obsolete CIs. You can configure the scheduled job to run at a specific frequency and time, and specify the criteria for selecting the CIs to delete.
