CIS-Discovery Practice Questions

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.

The ECC Queue is the normal connection point between an instance and other systems that integrate with ServiceNow, such as MID Servers1. The ECC Queue displays input and output messages from and to MID Servers2. The actual XML payload that is sent to or from an instance is stored in the ECC Queue3. The ECC Queue also provides a connected flow of probe and sensor activity, as probes are sent from the instance to the MID Server, and sensors are sent from the MID Server to the instance2.

 Discovery can provide information about the relationships between configuration items (CIs), including applications and hosts. Application relationships are the connections between applications that run on different hosts or servers, such as web servers, databases, load balancers, etc. Host relationships are the connections between applications and the hosts or servers that they run on, such as Windows, Linux, Unix, etc. Discovery can identify these relationships using various methods, such as probes, sensors, patterns, file-based discovery, etc. Discovery can also create and update these relationships in the CMDB, using the Depends on::Used by or Runs on::Runs relationship types.
