Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
CI Class Manager
Why this is correct
CI Class Manager provides a dedicated interface to add attributes to classes and manages the table inheritance properly.
- ✗
Table Builder on cmdb_ci_linux_server
Why it's wrong here
While Table Builder works, CI Class Manager is the recommended best practice framework for CMDB class customizations.
- ✗
System Definition > Custom Fields
Why it's wrong here
There is no standard 'Custom Fields' module under System Definition for CMDB class attributes.
- ✗
Dictionary Editor on cmdb_ci
Why it's wrong here
Adding attributes directly to cmdb_ci makes the attribute global to all CIs, which may not be desired for a server-specific attribute.
