The 'CMDB Import' application is not a standard method for populating the CMDB. ServiceNow does not have such an application; the correct approach would be using Import Sets or Discovery.

Trap 2: Manually creating CIs using the 'New' button on the CMDB module.

Manually creating CIs is possible but is not considered a method to 'populate' the CMDB, as it is a manual, individual entry rather than a bulk or automated population method.

Trap 3: Configuring LDAP integration to synchronize user and computer…

LDAP integration is used to import users and groups from directory services, not configuration items. It does not populate the CMDB.

A
Using the 'CMDB Import' application to upload data from external tools.
Why wrong: The 'CMDB Import' application is not a standard method for populating the CMDB. ServiceNow does not have such an application; the correct approach would be using Import Sets or Discovery.
B
Running ServiceNow Discovery to automatically identify and populate CIs.
Correct. ServiceNow Discovery is a primary automated method that uses probes and sensors to identify and populate CIs into the CMDB.
C
Manually creating CIs using the 'New' button on the CMDB module.
Why wrong: Manually creating CIs is possible but is not considered a method to 'populate' the CMDB, as it is a manual, individual entry rather than a bulk or automated population method.
D
Configuring LDAP integration to synchronize user and computer objects.
Why wrong: LDAP integration is used to import users and groups from directory services, not configuration items. It does not populate the CMDB.
E
Importing a CSV file directly into the cmdb_ci table using the Import Set feature.
Correct. Importing a CSV file via the Import Set feature is a standard method for populating the CMDB with data from external sources, provided the data is staged and mapped correctly.
