Selected Answer: A

Correct Answer: A. Deploy Directory Connector Deploying the Directory Connector allows for the synchronization of user directories, which is crucial for integrating on-premises collaboration systems with Webex cloud services. This ensures that users can access Webex services using their existing enterprise credentials and identities. D. Referring to the Cisco Espressway Connector is only integrating the messaging service, so that users on-prem and cloud can communicate.

Answer is D Hybrid Messageconnects your Unified Communications Manager IM and Presence Service(IM and Presence Service) to Webex to enable interoperability with Webex App. The Hybrid Messageenables interoperability between these two groups of users. The components that make Hybrid message possible are the message connector, hosted on Cisco Expressway infrastructure on your premises, and the Message Service, running in the Webexcloud. https://www.cisco.com/c/en/us/td/docs/voice_ip_comm/cloudCollaboration/spark/hybridservices/messageservice/cmgt_b_spark-hybrid-message-deployment-guide/cmgt_b_spark-hybrid-message-deployment-guide_chapter_00.html Directory Connector only Sync directory between on-premise and cloud.

Because the interop with the webex app implies the existence of a Cisco Jabber deployment and to make that happen, the Webex Hybrid Message Service must be enabled, which requires the Cisco Expressway Message Connector host to be deployed.
