An engineer is building a Cisco Unity Connection user account. Which type of account should the engineer choose if using a prepopulated extension that requires the ability to change the extension in…

A corporate directory synchronized user maintains an ongoing sync with the LDAP directory, meaning any manual change to the extension can be overwritten the next time synchronization runs.

A local Cisco Unity Connection user is created entirely by manual entry with no prepopulated data from an external directory, so the extension would not be prepopulated.

A CUCM import account pulls user data from CUCM end-user records rather than directly from an LDAP or Active Directory source, so it does not fulfill the LDAP-prepopulation requirement.

LDAP import creates a Unity Connection user with fields including the extension prepopulated from the LDAP directory, but because it is an import rather than a continuous synchronization, the extension and other fields can be manually edited afterward without being overwritten by a subsequent directory sync.
