For Hybrid Services to be fully enabled with Cisco Spark, how many connectors must be...

Hybrid Services are a set of features that allow you to connect your on-premises or partner-hosted Cisco collaboration components to the cloud-based Cisco Spark capabilities1.

Connectors are software modules that run on Expressway-C or Expressway-E and provide secure communication between your premises environment and the cloud1.

To enable Hybrid Services with Cisco Spark, you need to establish four connectors in your premises environment123:

Calendar Connector: This connector integrates your on-premises Microsoft Exchange or Office 365 calendar with Cisco Spark, enabling users to schedule and join meetings from their calendar applications or devices1.

Call Service Connector: This connector enables Cisco Spark to use your on-premises call control (Cisco Unified Communications Manager or Cisco Business Edition) for PSTN calling, extension dialing, and desk phone control1.

Directory Connector: This connector synchronizes your on-premises Active Directory or LDAP directory with Cisco Spark, allowing users to search and communicate with their colleagues using their corporate email addresses1.

Serviceability Connector: This connector collects diagnostic data and logs from your on-premises devices and components and uploads them to the cloud for troubleshooting and analysis1.

The other options are incorrect because:

A. 2 is too few for Hybrid Services to be fully enabled with Cisco Spark. You need at least three connectors (Calendar, Call Service, and Directory) to enable the core features of Hybrid Services1. The Serviceability Connector is optional but recommended for support and maintenance1.

C. 3 is also too few for Hybrid Services to be fully enabled with Cisco Spark. You need all four connectors (Calendar, Call Service, Directory, and Serviceability) to enable the full functionality and benefits of Hybrid Services1.

D. 1 is not enough for Hybrid Services to be fully enabled with Cisco Spark. You need four different connectors (Calendar, Call Service, Directory, and Serviceability) to enable different aspects of Hybrid Services1.
