CIS-Discovery Exam Questions & Answers

When increasing the maximum number of threads for a MID Server in ServiceNow Discovery, it's often necessary to also increase the memory allocated to the MID Server application. This is because more threads can result in higher memory usage as each thread may consume resources while performing discovery tasks. Increasing disk space, updating ACL rules for CMDB tables, or increasing the MID Server max payload size are not directly related to the number of threads used by a MID Server. Reference = ServiceNow Discovery documentation, especially sections discussing MID Server configuration and performance tuning.

The Shazzam probe is placed in the ECC queue as a first step in horizontal discovery.The ECC queue is a table that stores requests and responses for communication between the MID Server and the ServiceNow instance1.The Shazzam probe is a script that performs port scanning on a target host to determine what protocols are available and what classifiers to trigger2.The Shazzam probe is sent from the ServiceNow instance to the MID Server, which executes it on the target host and returns the results to the ECC queue3.

CMDB Health measures the quality of the data in the CMDB by testing it against predefined rules and metrics.One of the categories of these rules isCorrectness, which tests the data against data integrity rules such as identification rules, orphan CI rules, and stale CI rules1.These rules help identify and flag the existing CMDB relationships that are not compliant with the suggested relationships2.

Duplicaterelationships are those that have more than one relationship of the same type between the same two CIs3. For example, if a server CI has two relationships of type ''Depends on'' with the same network CI, it is a duplicate relationship.

Stalerelationships are those that have not been updated for a specified period of time3. For example, if a server CI has a relationship of type ''Runs on'' with a virtual machine CI that has not been discovered for more than 60 days, it is a stale relationship.

Orphanrelationships are those that are missing a defined relationship within the CMDB3. For example, if a server CI has no relationship of type ''Depends on'' with any network CI, it is an orphan relationship.

A classifier is a set of rules that identifies a device type based on the results of a probe. A classifier can have one or more related lists that define the classification criteria, the pattern probes, and the triggers probes. The pattern probes related list specifies which horizontal discovery pattern to run for the device type. The triggers probes related list specifies which probes to run after the device is classified, and before the horizontal discovery pattern is executed.The triggers probes can be used to gather additional information or credentials that are needed for the horizontal discovery pattern12.
