VDV Chapter 2 (Cisco Voice Video Data Chapter 2) with Complete Questions and Answers!!

Cisco Unified Communications Manager (CUCM) - ANSWER-Full support for audio and video telephony: Appliance-based operation: Modern CUCM versions run as an appliance, which means the underlying operating system is hardened (secured) and inaccessible. Redundant server cluster: Scales to 30,000 IP phones in insecure mode or 27,000 in secure mode. Intercluster and voice gateway control and communication: Built-in Disaster Recovery System (DRS): As a built-in feature, the CUCM DRS service allows you to back up the CUCM database (and any additional files you'd prefer) to a network device or over Secure FTP (SFTP). VMWare Virtualization Support: If you love VMWare, you'll love the fact that CUCM 8.0 is supported in a VMWare ESXi environment. Directory service support or integration: VoIP networks can use network user accounts for a variety of purposes (phone control, attendant console control, and so on). CUCM has the capability to be its own directory server to hold user accounts or it can integrate into an existing corporate directory structure CUCM Database Relationship - ANSWER-The CUCM IBM Informix database includes all the "static" data of the cluster (directory numbers, route plan, calling permissions, and so on). This data replicates to all the servers in the cluster. Replicated from the "publisher" to the "Subscribers CUCM Runtime Data - ANSWER-Just like the name sounds, the runtime data encompasses anything that happens in "real time" in the CUCM cluster. For example, when a device registers with a CUCM server, it communicates to all the other servers that it now "owns" that IP phone. CUCM uses a method designed specifically by Cisco for this type of communication: Intracluster Communication Signaling (ICCS). Cisco Unified Contact Center - ANSWER-Allows you to add call-center capabilities to your network, such as skills-based call routing, call queuing, live monitoring of conversations Cisco Unified MeetingPlace - ANSWER-Adds enhanced conference-call capabilities, document collaboration, and training platforms.
