ServiceNow CIS-Discovery Exam With Confidence Using Practice Dumps

A /24 subnet IP Range means that there are 256 possible IP addresses in the range, from 0 to 255. A Shazzam batch size of 5000 means that Discovery will send 5000 ICMP packets at a time to scan the IP addresses. Therefore, Discovery will launch the Shazzam probe once for every 5000 IP addresses in the range, or 256 / 5000 = 0.0512 times. Since the number of times must be an integer, Discovery will round up to 1 and launch the Shazzam probe once. However, since the Shazzam probe is launched for each MID Server that is assigned to the Discovery Schedule, the actual number of times will depend on how many MID Servers are available. If there are N MID Servers, then the Shazzam probe will be launched N times, each sending 5000 ICMP packets to the same IP range. Therefore, the total number of times that the Shazzam probe will be launched during discovery is N * 1 = N.

CI identifiers can be viewed under the CI record1. A CI identifier is a set of attributes that uniquely identify a CI of a specific class2. CI identifiers are used by the identification and reconciliation engine (IRE) to match incoming data with existing CIs in the CMDB3. CI identifiers can be viewed and edited in the CI record by clicking the Identification Information related link1.

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.
