• The Session Description Protocol (SDP) is a protocol that defines a text-based format for describing the multimedia sessions and the media streams involved in them12.
• SDP is used to convey information such as the session name, purpose, originator, timing, media types, codecs, formats, transport protocols, ports, addresses, encryption keys, bandwidth, and other attributes12.
• SDP is typically used in conjunction with other signaling protocols, such as SIP, H.323, or RTSP, to establish and control the multimedia sessions12.
• SDP does not itself provide any mechanism for transporting the media streams; it only describes them. The actual media transport is done by protocols such as RTP, which uses the information provided by SDP to set up the appropriate ports and codecs12.

The Cisco Meeting Server (CMS) uses a RESTful API to configure settings on the server. The RESTful API allows the user to perform CRUD (Create, Read, Update, Delete) operations on the CMS resources using HTTP methods such as GET, POST, PUT, and DELETE. The RESTful API also supports JSON and XML formats for the request and response bodies. The CMS web interface and the Cisco Meeting Management (CMM) application use the RESTful API to communicate with the CMS. The other options are not valid types of API for the CMS. References: Cisco Meeting Server API Reference Guide, Cisco Meeting Server Basic API Functions

 Cisco TMS (TelePresence Management Suite) is the application that is integrated with the CMR solutions to provide for conference scheduling. Cisco TMS allows users to schedule video conferences using a web interface, Microsoft Outlook, or Cisco Jabber. Cisco TMS also providesmanagement and monitoring of video endpoints and infrastructure, as well as reporting and analytics123 References := 1Cisco Collaboration Meeting Rooms (CMR) Premises Solution Guide Release 5 2Cisco TelePresence Management Suite - Products & Services - Cisco 3Configure Bridge Scheduling - Cisco

• A cluster is a group of Expressways that share configuration and information, and act as one large Expressway Local Zone1.
• Clustering is used to increase the capacity and resilience of the Expressway deployment1.
• The maximum number of Expressways that can be clustered is six123.
• However, the capacity gain from clustering is limited to a maximum factor of four, except for Small VMs, which have no gain2.
• For Small VMs, clustering is only for redundancy and not for scale2.

The SIP message that is sent from the called endpoint after the call request is accepted is “200 OK”. This message indicates that the called endpoint has agreed to participate in the session and is ready to receive media. The “200 OK” message also contains the session description protocol (SDP) information that specifies the media capabilities and parameters of the called endpoint, such as the codec, the port number, and the encryption method. The “200 OK” message is sent as a response to the “INVITE” message that was sent by the caller to initiate the session. The caller then acknowledges the “200 OK” message by sending an “ACK” message, which completes the session establishment12

The other options are not valid SIP messages that are sent from the called endpoint after the call request is accepted. “Hello” is not a SIP message at all, but a common greeting. “404 OK” is a nonsensical combination of a SIP error code and a SIP status code. “404” means “Not Found”, which indicates that the requested user or service does not exist or is not available. “OK” means “Success”, which indicates that the request was fulfilled. These two codes are contradictory and cannot be used together. “Connect” is not a SIP message either, but a generic term for establishing a link or a communication34 References: SIP - Basic Call Flow - Online Tutorials Library, Understanding SIP INVITE method and messages - Wildix blog, Session Initiation Protocol - Wikipedia, Basic SIP Call Flows & Troubleshooting Commands - Cisco Community

= SIP (Session Initiation Protocol) is the protocol that is used for VoIP and other multimedia applications. SIP uses port 5060 for non-encrypted signaling traffic and port 5061 for traffic encrypted with Transport Layer Security (TLS). These are the ports that SIP clients typically use to communicate with SIP servers and other endpoints1234 References := 1Session Initiation Protocol - Wikipedia 2SIP Port Numbers used by Providers - WhichVoIP 3What is a SIP port? | FREEZVON 4An Introduction to SIP Protocol: Definition, Features, & More - Nextiva

• The Cisco Conductor is a software application that provides intelligent resource management and conference orchestration for video conferencing deployments1.
• The service preference is a configuration option in the Cisco Conductor that defines the order of preference for using different bridge pools for a conference2.
• A bridge pool is a logical grouping of one or more conference bridges that share the same characteristics, such as location, capacity, media encryption, and conference type2.
• The service preference consists of one or more bridge pools and it determines which of these pools, in order of priority, to use for a conference2.
• The service preference is applied based on the conference alias that is used to initiate or join a conference2.
• The service preference does not determine the conference template, the bandwidth, or the conference alias for a conference. These are determined by other factors, such as the call control system, the conference scheduling system, or the conference bridge configuration2.

= Transforms are a way of modifying the destination alias or address of a call before it is routed to the appropriate zone or service. Transforms can be applied at different stages of the call routing process, such as pre-search, search rules, or call policy. The Cisco recommended method to add a domain to a numeric E.164 alias dialed by an H.323 endpoint is to use a pre-search transform. A pre-search transform is applied to the destination alias before any searches are sent to external zones. This allows the Expressway to standardize the destination aliases originating from both H.323 and SIP devices. For example, if the called address is an H.323 E.164 alias “01234”, the Expressway can automatically append the configured domain name (in this case example.com) to the called address (that is, 01234@example.com making it into a URI), before attempting to set up the call. This way, the Expressway can route the call to the correct destination zone or service based on the full URI. References := Cisco Expressway-E and Expressway-C Basic Configuration Deployment Guide (X14.0) - Routing ConfigurationCisco Expressway Administrator Guide (X14.0) - Dial Plan and Call Processing

• A rendezvous conference is a type of conference that allows participants to join by dialing a predefined alias or URI1.
• To deploy Cisco Conductor with Cisco Telepresence Server for rendezvous conferences, you need to configure the following components2:
• To enable the communication between the Cisco Expressway and the Cisco Conductor, you need to create a neighbor zone and search rules on the Expressway3. A neighbor zone is a logical connection to another SIP or H.323 device that allows direct routing of calls without registration4. A search rule is a set of criteria that determines how to route a call based on the dialed alias or URI5.
• The neighbor zone and search rules must be built between the Expressway and the Conductor, not between the Expressway and the TelePresence Server, because the Conductor is the one that manages the conference resources and assigns the TelePresence Server to the rendezvous conference2. The TelePresence Server is registered to the Conductor as a conference bridge and does not need a direct connection to the Expressway6.
• Therefore, the correct answer is C. A neighbor zone and search rules must be built between the Expressway and the Conductor.

= The scaled and resilient server deployment model is the best solution to accommodate fail-over for Cisco Meeting Server. This model involves deploying multiple Meeting Servers clustered together to provide greater scale and resilience in the deployment. The cluster can span across different locations and support up to 2500 HD ports. The cluster can also handle the failure of one or more servers without affecting the ongoing conferences or the user experience. The cluster uses a load balancer to distribute the incoming calls among the available servers, and uses a database replication mechanism to synchronize the conference state and configuration across the servers123 References := 1Cisco Meeting Server - Configuration Guides 2CiscoMeeting Server 3.8, Scaled and Resilient Server Deployment Guide 3Cisco Meeting Server 3.8, White Paper on Load Balancing Calls Across Cisco Meeting Servers
