Correct answers: A three-node database cluster with one master and two slaves.; An external load balancer to distribute traffic across multiple Call Bridge nodes.

For database redundancy in a large-scale CMS deployment, a three-node (or five-node) database cluster is required to maintain quorum and handle failover. A single database is a single point of failure. A load balancer is essential for distributing traffic across the Call Bridges.

To achieve scalability for 2,000 calls, multiple Call Bridge nodes are necessary. An external load balancer (like F5 or Citrix ADC) is required to distribute the incoming call load efficiently and evenly across these nodes.

Correct answer: Creating a new user group and assigning it 'Booking' and 'Endpoint Control' permissions with 'Folder' scope.

Cisco TMS provides granular, role-based access control (RBAC). To restrict a user's permissions to a specific folder, you must create a user group, assign the necessary permissions (like 'Booking'), and set the scope of those permissions to 'Folder'. The administrator would then be granted access only to the specific folder(s) assigned to that group. Default groups have global scope, and user-level permissions override group settings but are harder to manage.

Correct answer: The Calendar Connector on the Expressway-C.

The Cisco Hybrid Calendar Service is responsible for integrating on-premises Microsoft Exchange (or Office 365) with the Webex cloud to enable features like @webex scheduling. This service is enabled by deploying the Calendar Connector software on the Expressway-C, which then communicates with the Exchange environment and the Webex cloud. The Directory Connector is for user synchronization, TMSXE is for TMS scheduling, and Expressway-E provides traversal but does not host the connector.

Correct answer: Firewall rules are blocking inbound UDP media traffic from the Webex cloud IP range to the Expressway-E.

This classic one-way video scenario in a hybrid deployment points to a firewall issue. The on-premises endpoint can send its media (outbound UDP) to the Webex cloud, so cloud participants can see it. However, the media from the cloud participants (inbound UDP) is being blocked by the external firewall before it can reach the Expressway-E and be relayed to the on-premises endpoint. Ensuring the Webex cloud's IP address ranges are allowed for inbound UDP traffic to the Expressway-E is the correct solution.

Correct answer: To define the maximum aggregate bandwidth available for all calls traveling between the two specified locations.

In Expressway's Call Admission Control (CAC) model, a 'pipe' represents a network link and is used to define the total amount of bandwidth available between two locations (subzones or zones). When a call is placed between these locations, Expressway checks if there is sufficient bandwidth remaining in the pipe. If not, the call is rejected. This prevents oversubscription of the physical network link and ensures call quality.

Correct answer: True

This statement is true. The Web Bridge component of Cisco Meeting Server is stateless and can be deployed behind a standard load balancer for high availability and scalability. Its clustering is independent of the stateful Call Bridge cluster, which requires more complex peering and database replication for resilience.

Correct answer: Creating and applying a Configuration Template to all relevant endpoints or folders.

The most efficient and scalable method is to use Configuration Templates in TMS. An administrator can define all the required security settings in a single template and then apply it to individual systems, folders, or the entire system tree. TMS will then automatically provision the endpoints with these settings and can be configured to periodically check for and correct any configuration drift, ensuring compliance.

Correct answer: Register a new bot application to obtain a Bot Access Token.

To interact with Webex APIs, every application, including a bot, must be registered in the Webex for Developers portal (developer.webex.com). This registration process generates a unique Bot Access Token. This token must be included in the authorization header of every API request the bot makes, authenticating it to the Webex cloud and granting it permissions based on its defined scopes.

Correct answer: Create two bridge pools, one for each location, and configure a Service Preference with the primary data center pool having a higher priority (lower number).

Cisco TelePresence Conductor uses Service Preferences to control which bridge pool is selected for a conference. By creating two bridge pools (one for each site) and a Service Preference that lists the primary site's pool with a lower priority number (e.g., Priority 10) and the DR site's pool with a higher number (e.g., Priority 20), the Conductor will always attempt to use the primary server first. It will only use the DR server if the primary is unavailable or has no capacity.

Correct answers: Installing a publicly trusted CA-signed server certificate with the CUCM FQDNs in the Subject Alternative Name (SAN) field.; Establishing a default traversal server zone that requires TLS verification.

A publicly trusted CA-signed certificate is mandatory for Expressway-E to establish secure TLS connections with external clients (MRA, B2B). The certificate's SAN must include all FQDNs that clients will use to connect, including the collaboration edge domain(s). A default traversal zone using TLS is the standard mechanism for secure communication between Expressway-E and Expressway-C.

The traversal zone between Expressway-E and Expressway-C is the secure tunnel for all internal communications. Configuring this as a TLS-verified zone ensures that the signaling and media proxying between the DMZ and the internal network are encrypted and authenticated.
