= The traversal subzone is a conceptual subzone that does not have any registered endpoints. Its sole purpose is to control the bandwidth that is used by traversal calls. Traversal calls are calls that pass through a firewall or a NAT device, using a pair of Expressways (one acting as a traversal client and the other as a traversal server). The traversal subzone allows theadministrator to set a limit on the total bandwidth that can be used by traversal calls, as well as the bandwidth per call. This helps to optimize the network resources and prevent congestion123 References := 1Concept of Zones Demystified On Cisco Expressway Series 2Cisco Expressway Administrator Guide (X14.3) - Clustering and Peers 3Cisco Expressway Administrator Guide (X14.0) - Bandwidth Control

 Microsoft Skype for Business (S4B) interoperability with Cisco Meeting Server (CMS) allows S4B users to join CMS meetings and vice versa. Chat can be used between S4B and Cisco Meeting App (CMA) users, as both support the SIP SIMPLE protocol for instant messaging. However, chat cannot be used between S4B and Cisco Meeting Server Spaces, as Spaces do not support chat functionality. Calls can be placed between S4B and CMA users, as both support the H.264 video codec and the Opus audio codec. Local directories can be used between S4B users and CMA, but only if the CMA is configured to use the same domain as the S4B server. References: Configure Cisco Meeting Server and Skype for Business, Plan for Video Interop Server in Skype for Business Server, Deploy Video Interop Server in Skype for Business Server

 123, a Cisco Meeting Server 2000 can support up to 108 simultaneous HD calls. A Cisco Meeting Server 2000 is a Cisco UCS x86 server that runs the Cisco Meeting Server software, which is a scalable and interoperable video conferencing solution. A Cisco Meeting Server 2000 has 36 physical cores and can support up to 3 HD calls per core, resulting in a maximum capacity of 108 HD calls. A HD call is defined as a call with a resolution of 720p at 30 frames per second and a bitrate of 1.2 Mbps. A Cisco Meeting Server 2000 can also support other call types, such as SD, nHD, and audio-only, with different capacities and bandwidth requirements. References := Cisco Meeting Server, Web App, and Meeting Management Revolutionize Team Collaboration Through High Scale and Advanced Interoperability in Audio, Web, and Video Conferencing Data SheetCisco Meeting Server - Cisco Meeting Server - CiscoCisco Meeting Server - Cisco Meeting Server - Cisco

 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 template is being persistently pushed to the endpoint from TMS. This is because TMS, or Cisco TelePresence Management Suite, is a software application that enables centralized management of Cisco video conferencing and collaboration devices and systems. TMS can use templates to configure and update multiple endpoints with the same settings, such as alias information, network settings, security settings, and so on1. If a template is applied to an endpoint, any manual changes made to the endpoint will be overwritten by the template settings the next time the template is pushed by TMS2. Therefore, if an administrator notices that the alias information changes revert back to their original state the following day, it is most likely that a template is being persistently pushed to the endpoint from TMS.

The other options are not correct because:

The changes are not being saved properly on the endpoint: This is not likely, as the changes are successful and visible on the endpoint until the next day. If the changes were not saved properly on the endpoint, they would not take effect at all or would be lost after a reboot or power cycle of the endpoint3.

A template is being pushed persistently to the endpoint from the Expressway: This is not possible, as the Expressway does not support pushing templates to endpoints. The Expressway is a network device that provides firewall traversal, NAT, and encryption services for video communications. The Expressway does not have the capability to configure or update endpoints with templates.

The alias information of the endpoint is duplicated on another endpoint: This is not relevant, as the alias information of the endpoint is not affected by the alias information of another endpoint. The alias information is a unique identifier for the endpoint that is used for registration and dialing purposes. The alias information of another endpoint does not overwrite or interfere with the alias information of the endpoint in question.

Cisco Meeting Server is a software application that provides scalable, secure, and interoperable video, audio, and web conferencing on premises or in the cloud1.

Cisco Meeting Server has several components that can be enabled to expand the functionality of the server, such as2:

Web Bridge: This component provides web-based access to meetings using WebRTC or Cisco Meeting App.

Load Balancer: This component distributes the load of incoming calls and web requests across multiple Call Bridges and Web Bridges.

TURN Server: This component provides firewall and NAT traversal for media streams using the TURN protocol.

H.323 Gateway: This component provides interworking between different communication protocols, such as SIP, H.323, and WebRTC.

SIP Edge: This component provides secure SIP signaling and media encryption for external endpoints and servers.

Call Bridge: This component hosts the conferences and provides transcoding, layout, and recording services.

XMPP: This component provides chat and presence services using the XMPP protocol.

The component that is used for interworking between different communication protocols is the H.323 Gateway2. The H.323 Gateway allows Cisco Meeting Server to communicate with endpoints and servers that use different protocols, such as H.323, SIP, or WebRTC. The H.323 Gateway can also provide protocol conversion, media encryption, and bandwidth management for the interworked calls2.

Therefore, the correct answer is D. H.323 gateway.

TMS stands for TelePresence Management Suite, which is a software application that provides centralized management, scheduling, and monitoring of video conferencing endpoints and infrastructure1.

TMS uses two primary protocols to communicate with endpoints and infrastructure: SIP and SNMP23.

SIP stands for Session Initiation Protocol, which is a signaling protocol that is used to establish, modify, and terminate multimedia sessions, such as voice and video calls. TMS uses SIP to communicate with endpoints and infrastructure that support SIP, such as Cisco Unified Communications Manager, Cisco Expressway, Cisco Meeting Server, and Cisco TelePresence endpoints23.

SNMP stands for Simple Network Management Protocol, which is a protocol that is used to monitor and manage network devices, such as routers, switches, servers, and endpoints. TMSuses SNMP to communicate with endpoints and infrastructure that support SNMP, such as Cisco TelePresence System MXP series, Cisco TelePresence Server, and Cisco TelePresence Conductor23.

TMS also uses other protocols, such as HTTP/HTTPS, XML, and SOAP, to communicate with endpoints and infrastructure, depending on the type and version of the system23.

An IDE tool is a software application that provides comprehensive facilities to computer programmers for software development. An IDE normally consists of a source code editor, build automation tools, and a debugger. Cisco Spark is a cloud-based collaboration platform that allows users to create, share, and communicate with each other. Cisco Spark supports various programming languages, such as Python, Java, Node.js, and C#. To develop applications for Cisco Spark, developers need an IDE tool that can work with these languages and interact with the Spark APIs. 1234, one of the IDE tools that can be used with Cisco Spark is OSX: Atom. Atom is a free and open-source text and source code editor for macOS, Linux, and Windows with support for plug-ins written in Node.js, and embedded Git Control, developed by GitHub. Atom can be customized to work with different languages and frameworks, such as Python, Java, Node.js, and C#. Atom also has a package called spark-tools that provides a set of tools for developing Cisco Spark applications, such as creating bots, webhooks, andintegrations. References := 1: Useful Developer Tools | Apache Spark 2: Create and run Spark application on cluster | IntelliJ IDEA 3: Spark development process with Python and IDE - Stack Overflow 4: Setting up IDEs — PySpark 3.5.0 documentation - Apache Spark : spark-tools package - Atom

 TMS, or Cisco TelePresence Management Suite, is a software application that enables centralized management of Cisco video conferencing and collaboration devices and systems. TMS relies on the following two operating systems and database applications1:

Windows Server: TMS requires a Windows Server operating system to run. The supported versions are Windows Server 2019, 2016, and 2012 R22.

SQL: TMS requires a SQL database application to store and manage data. The supported versions are SQL Server 2019, 2017, 2016, and 20142.

The other options are not correct because:

Oracle: TMS does not support Oracle as a database application. TMS only supports SQL Server as a database application2.

MS Access: TMS does not support MS Access as a database application. TMS only supports SQL Server as a database application2.

Linux Ubuntu: TMS does not support Linux Ubuntu as an operating system. TMS only supports Windows Server as an operating system2.

= To schedule a CMS conference on TMS with WebEx as a participant, the engineer needs to ensure that the WebEx server address is correctly configured in both TMS and CMS. This is because TMS uses the WebEx server address to create an externally hosted conference with a WebEx SIP URI, and CMS uses the WebEx server address to dial out to the WebEx meeting. The WebEx server address can be configured in TMS under Administrative Tools > Configuration > Network Settings > WebEx Settings, and in CMS under Configuration > WebEx. The WebEx server address should match the WebEx site URL that is used to join the WebEx meeting12. References := 12
