Exam 350-801 topic 1 question 271 discussion

It is a question very tricky, it is not difficult, just take care with the semantics in each one of the answers: A. and B. are incorrect, SCCP and SIP do not affect voicemail configuration. Check the answer D. saying "...to sync the users WHO WILL have a voicemail...", it is incorrect: The LDAP synchronization process does not automatically import users from LDAP into the Cisco Unity Connection database. In order to import users, you must select the template to use for applying the various features specific to Cisco Unity Connection. By selecting a user template there, you not only select users with voicemail, rather you can select users with or without voicemail or just contacts, these task can not be performed just with sync. So, C. is incorrect. ANd finally, C. is the closest answer, because for being a short and concrete answer, which is to access the Cisco UCM users and nothing else. C. is correct.

In Unity Connection, users can be imported from two sources Cisco Unified Communications Manager (CUCM) and Active Directory (AD). Users imported from CUCM are known as Administrative XML (AXL) imported users. Users imported from Active Directory are known as Lightweight Directory Access Protocol (LDAP) imported users. https://www.cisco.com/c/en/us/support/docs/voice-unified-communications/unity-connection/116035-cuc-userimport-00.html

C. is correct answer.

SIP integration doesn't sync users automatically AXL server can be configured in CUC and then sync CUCM users to it. Another way is LDAP / AD configuration. I would go for C to sync CUCM users, which may not be AD integrated.
