The Certified Implementation Specialist - Discovery (CIS-Discovery)

From the Discovery Status record, a Device record in ServiceNow Discovery contains a link to the discovered Configuration Item (CI). This link provides direct access to the CI record that was discovered and processed during the discovery cycle. The Device record does not contain the contents of the CI, a link to the discovered Asset, or a link to the CMDB Health Dashboard. References = ServiceNow Discovery documentation, focusing on the details of Discovery Status records and the information contained within Device records.

The Debug Identification Section in Debug Mode allows you to specify the identification attributes of a CI that you want to debug. These attributes are used to find the CI in the CMDB and run the pattern on it. The identification attributes vary depending on the CI class, but for infrastructure patterns, the common ones are IP and Host Name. These attributes are also used by the horizontal discovery to identify CIs. AWS Endpoint and PID are not valid identification attributes for infrastructure patterns.

Tracked configuration files are files that contain settings and parameters of certain applications or devices that Discovery can find and add to the CMDB. Some of the benefits of tracked configuration files are:

Content version comparison: You can compare the content of different versions of the same configuration file and see the changes that occurred over time. This can help you troubleshoot issues, audit changes, and restore previous configurations if needed.

Files tracked as CIs: You can view the configuration files as configuration items (CIs) in the CMDB and see their relationships with other CIs, such as the applications or devices they belong to. This can help you understand the dependencies and impact of the configuration files on your IT environment.

In a discovery pattern, CI Attributes are the fields that store the information about the configuration items (CIs) that are discovered by the pattern. The Pattern Designer is a graphical interface that allows users to create and edit patterns using drag-and-drop operations. In the Pattern Designer, there are two types of CI Attributes that are available: Main pattern CI type and Related CI types. The Main pattern CI type is the CI type that the pattern is designed to discover, such as Windows Server, Linux Server, or Database. The Related CI types are the CI types that are related to the main CI type, such as IP Address, Network Adapter, or Software Installation.  Users can select the CI Attributes from these types to populate the CMDB tables with the data collected by the pattern 1 2 3 .

When designing steps with operations requiring variables, it is best practice to query targets for variables 1 . This allows you to dynamically obtain the values of the variables from the target devices, rather than hard coding them or using scalar variables that may not reflect the current state of the target. Querying targets for variables also enables you to design for a dynamic environment, where the target configuration may change over time.

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. References = ServiceNow Discovery documentation, especially sections discussing MID Server configuration and performance tuning.

A is true because the target table $cmdb_ci_web_server is a ServiceNow CMDB table that stores information about web servers 1 .

B is true because the merge table operation is typically used for application patterns, which are horizontal patterns that discover applications and their dependencies. The condition on the process.executablePath variable suggests that the operation is looking for a specific application (mongoose) running on the web servers.

D is true because the merge table operation requires at least one matching field value between the two source tables 1 . In this case, the process.executablePath variable is the matching field, and it must contain “mongoose” for the operation to run.

Agent Collector is the component that executes the osquery commands on agents to gather attribute details from a CI.  Agent Collector is a feature of the Agent Client Collector (ACC) for Discovery, which is an integration that enables ServiceNow Discovery to use osquery to collect data from Linux and Windows devices that have the Elastic Agent installed 1 .  Agent Collector allows you to define osquery queries and assign them to policies that target specific devices or groups of devices 2 .  Agent Collector then runs the queries on the agents and sends the results back to the instance, where they are processed by the Agent Listener and stored in the CMDB 3 .

 Based on the web search results from the  search_web  tool, the following choices best represent key capabilities of a ServiceNow ITOM Enterprise solution:

Manage Hybrid Clouds: ServiceNow ITOM enables organizations to gain visibility into their IT environment, on-premises to cloud, and see the impact of their applications on business services 1 2 .  It also helps to plan, track, and secure cloud implementation through best-practice governance 1 .  Four apps comprise Cloud Accelerate to help prepare for cloud migration, streamline provisioning requests, and manage cloud resources 1 .

Proactively Eliminate Service Outages: ServiceNow ITOM helps to predict issues, reduce user impact, and automate resolutions with predictive AIOps and automation 1 3 .  It analyzes telemetry and log data using AI to reduce noise, expedite mapping and predict issues 1 .  It also delivers proactive digital operations with real-time log data to solve problems quickly 1 .

The other choices are not specific to ServiceNow ITOM Enterprise solution, but rather general features of the ServiceNow platform. The ServiceNow platform allows users to create an engaging user experience with intuitive interfaces and workflows. It also enables users to build new apps fast with low-code development tools and pre-built components.
