Final answer:
All technical configuration items extend from the Configuration Item [cmdb_ci] table. This table is the foundation in the hierarchy of a CMDB, ensuring that all CIs have a common set of attributes for consistent management and reporting.
Step-by-step explanation:
The student has asked about the base table from which all technical configuration items extend in a particular IT Service Management (ITSM) platform. The correct answer is D. Configuration Item [cmdb_ci]. In many ITSM systems, particularly in ServiceNow, the Configuration Item [cmdb_ci] table is the foundational table that holds the basic attributes shared by all configuration items (CIs) within the configuration management database (CMDB). Technical Configuration Items are a subset of this broader category and thus, they would extend from the Configuration Item [cmdb_ci] table as well.
When dealing with the CMDB in ServiceNow or a similar platform, understanding the table hierarchy is critical. The Configuration Item [cmdb_ci] table is at the top of this hierarchy, with various other tables that represent specific types of CIs, like Technical Configuration Item [technical_cmdb_ci], hardware, software, networks, etc., inheriting attributes from it. These inherited attributes ensure that, despite their differences, all CIs have a common set of fields that can be used for management and reporting.
