ServiceNow Discovery – Fundamentals Exam 2024

ServiceNow Discovery – Fundamentals Exam 2024 Network discovery -Answer-Network Discovery discovers the internal IP networks and subnets within your organization; Cloud discovery -Answer-Cloud discovery finds resources in AWS and Azure clouds, and then populates the CMDB with the relevant CIs and relationships. Two types: Service account cloud discovery & Cloud application discovery; Serverless discovery -Answer-Discovery can find applications on host machines without the need to discover the host first. Two type: Standard serverless discovery & Host- based serverless discovery; Discocery Dashboard displays -Answer-The Discovery Dashboard displays: 1 The current progress of the actively running schedules. 2 Discovered devices, by category and time discovered. 3 Errors that occurred during a schedule that has run. 4 Credentials that were either not required or unused by a schedule Discovery status -Answer-The Discovery status provides a summary of a Discovery launched from a schedule. You can also cancel a Discovery that is in progress from the status form Discovery status reference lists -Answer-* Discovery Log: classification failures, CMDB updates, and authentication failures * ECC queue entried: connected flow of probe and sensor activity, actual XML payload. * Device history: summary of all the devices scanned during discovery, and what action sensors took on the CMDB Include alive -Answer-includes devices on which one port responded to the scan, but no ports are open Discovery Log -Answer-classification failures, CMDB updates, and authentication failures Discovery Pattern Log -Answer-includes Horizontal Discovery log records, which display information about discoveries that were performed with patterns. A horizontal discovery log record is created for an entire horizontal discovery run, which includes the results of all the operations specified in the pattern. Why use Discovery status? -Answer-to see a summary of a Discovery, access the ECC queue (shows probe and sensor activity), as well as the actual XML payload Why use Discovery dashboard? -Answer-to monitor ongoing Discovery operations Why use Discovery CI schedule manager? -Answer-to access a report of all discovered devices, see any errors that might have occurred, and view discovery trends. This manager interface shows data for Configuration Item type discoveries. What are the steps for: MID Server auto selection -Answer-1 appropriate IP range configured 2 ALL application and appropriate IP range configured 3 more then 1, then first that is Up else random 4 none are up, default MID Server specified for the Discovery application 5 no default MID Server, then default MID Server specified for the ALL application, assuming it is up. 6 If no default MID Server is specified, cycles through the previous steps and looks for MID Servers with the status of Paused or Upgrading Auto select steps for MID Server clusters in load balanced -Answer-1 first MID Server in the cluster that it finds with the status of Up 2 more up, random select one else Paused or Upgrading Auto select steps for MID Server clusters in fail over -Answer-1 MID Server with the lowest Order value that also has the status of Up 2 else Paused or Upgrading Where can you set the Shazzam batch size? -Answer-on the Discovery schedule What is the default batch size for Shazzam? -Answer-5000 When not to use MID server clusters? -Answer-LDAP Export sets JDBC data sources When can you get duplicated discovery data ,using a MID server? -Answer-When a fail over MID server starts it is always begins with first ECC entry What are capabilities? -Answer-MID Server capabilities define the specific functions of a MID Server within an IP address range What capabilities are available? -Answer-All Cloud Management Nmap PowerShell Resolve DNS REST SNMP SOAP
