CIS-Discovery Exam Dumps : Certified Implementation Specialist - Discovery

The SNMP Query operation on a pattern for a custom device query allows Discovery to retrieve information from the target device using the SNMP protocol. It is best practice to use the published manufacturer’s device MIB, which is the official and standard definition of the device’s SNMP data. Using the manufacturer’s device MIB ensures that the query is accurate, consistent, and compatible with the device. Modifying the default MIB information, enabling SSH as a secondary protocol, or using live devices in production are not recommended practices, as they may introduce errors, security risks, or performance issues123.

A Functionality Definition is a configuration record that defines what protocols to detect from within a Behavior. A Behavior is a set of Functionality Definitions that Discovery uses to identify and explore a device or application. A Functionality Definition specifies the order, type, and parameters of the probes that Discovery launches to gather information about a device or application12.

The $process.executableDir expression correctly calls the value of the executableDir variable from the tabular process variable. The process variable is a tabular variable that contains the output of the ps command, which lists the processes running on a CI. The executableDir variable is a column name that holds the directory path of the executable file for each process. To access the value of a column name from a tabular variable, you need to use the dot notation, such as $variable.columnName12.
