Exam 500-301 topic 1 question 10 discussion

"which allow simple screen sharing between the two users" option C is correct. It would be option B if we talk about Call Service Connect "Call Service Connect to integrates Cisco Spark with an existing Cisco call control platform, thus, making it possible for users to make and receive calls on their Cisco device or Spark application using the same dialing procedure as with on-premise registered endpoints."

Its a confusing question, I think the answer can be the B option as well. Here is a extract of OnDemand Learning Center: "Hybrid Call Services include two components, Call Service Aware and Call Service Connect. Call Service Aware makes Cisco Spark aware of all calls across your Unified Communications (UC) system, thus enabling the automatic creation of a one-to-one room whenever a point-to-point call is placed between two Spark users on their on-premises registered endpoints. This one-to-one room provides capabilities such as Zero Touch Meetings, which allow simple screen sharing between the two users. Call Service Aware also provides a unified call history; the Spark client shows missed and placed calls even if the client was not running at the time the call occurred."
