Which action must the engineer take to complete the configuration?
Options
- ADeploy Directory Connector.
- BOpen the TCP 443 port from IM and Presence to Webex Cloud.
- CDeploy a Webex Device Connector.
- DDeploy a Cisco Expressway Message Connector host.

Explanation
To enable interoperability between an on-premises IM and Presence deployment and the Webex App in the cloud (Hybrid Message Service), the engineer must deploy a Cisco Expressway Message Connector host. The Expressway-C runs the Message Connector component, which bridges messaging between on-premises IM&P and the Webex cloud. Directory Connector (A) handles user sync, not messaging. TCP 443 from IM&P to cloud (B) may be needed but is not the primary action. A Webex Device Connector (C) is for device management, not messaging interoperability.
