You are building a ServiceNow Discovery pattern for a Linux server that hosts multiple network interfaces. During pattern execution, you need to populate the CI's 'IP Address' field with the IP address of the interface that has the default route. The pattern step that runs the command 'ip route get 8.8.8.8' returns output similar to: '8.8.8.8 via 192.168.1.1 dev eth0 src 192.168.1.100'. You want to reliably extract only the source IP (192.168.1.100) and assign it to the CI attribute. Which pattern step type and configuration should you use?

You are designing a pattern to discover Linux servers. You need to ensure that the pattern only runs the 'Identify' step if the server's hostname matches a specific naming convention (e.g., starts with 'prod-'). Which Pattern Designer feature should you use to implement this conditional logic?

A discovery pattern must ensure that a CI is only created (not updated) when the identification process cannot find an existing record. The pattern currently has an Identification step that runs successfully. You need to configure the next step to execute only if the CI was not found. Which condition should you use in the step's 'Run if' condition?

You are designing a Discovery pattern that runs a command on a Linux host and then parses the output to populate the 'CPU core count' field on the CI. The command's output contains multiple lines, and the relevant number appears on the same line as the label 'CPU(s):'. Which Pattern Designer step configuration should you use to reliably extract the numeric value?

A pattern you authored is producing CI records, but a required attribute named 'serial_number' is sometimes populated and sometimes left blank depending on the device model.

A pattern designer is testing a new pattern for a network switch. The pattern includes a step that runs a command and parses the output. During testing, the designer notices that a specific attribute is not being populated even though the command output contains the expected value. The parsing step uses a regular expression. What is the most likely cause?
