CLCOR Cloud And Hybrid Services Practice Test 2 — 15 Questions

Question 1

Which TWO of the following are valid requirements for deploying the Cisco Directory Connector? (Choose two)

Accepted Answer

A Windows Server to host the connector software.. Option A is correct because the Cisco Directory Connector is a Windows-based application that must be installed and run on a supported Windows Server host (e.g., Windows Server 2016/2019), which performs the synchronization between Active Directory and the Webex cloud. Option E is correct because the connector must reach the Webex cloud APIs over HTTPS (TCP 443) to provision and sync users, so a direct outbound connection to the Webex cloud API is a valid requirement. Option B is not required because the Directory Connector synchronizes with the Webex cloud (Control Hub), not with an on-premises CUCM cluster. Option C is not required because the connector itself does not mandate a separate Webex Calling license per user; licensing is a separate entitlement concern. Option D is not required because the sync server only needs outbound internet access and does not need a dedicated public IP address.

Answer

An on-premises CUCM cluster.

Answer

A separate Webex Calling license for every user.

Answer

A dedicated public IP address for the sync server.

Question 2

What is the maximum number of nodes in a standard Expressway-C cluster for Hybrid Services?

Accepted Answer

6. A standard Expressway-C cluster for Hybrid Services supports a maximum of 6 nodes. This limit applies to the Expressway-C cluster that hosts the Hybrid Service connectors (Call, Calendar, Messaging, etc.) and is documented in Cisco's Expressway clustering guidelines for hybrid deployments.

Question 3

Which TWO of the following are benefits of using the Webex Hybrid Data Security (HDS) service? (Choose two)

Accepted Answer

It allows the customer to manage their own encryption keys.. HDS provides organizations with control over their encryption keys and ensures that sensitive metadata remains stored on-premises rather than in the public cloud.

Answer

It eliminates the need for user authentication.

Answer

It provides faster internet speeds for users.

Answer

It provides automatic PBX integration.

Question 4

Which THREE of the following are required for the successful operation of the Webex Hybrid Calendar service? (Choose three)

Accepted Answer

A valid configuration in Control Hub.. Option A is correct because the Webex Hybrid Calendar service must be enabled and configured in Control Hub, where the organization's calendar connector settings, resource types, and deployment mode are defined before the service can function. Option B is correct because an Expressway-C node is required as the on-premises connector that establishes the secure tunnel between the enterprise network and the Webex cloud for Hybrid Calendar (and related hybrid services). Option E is correct because a dedicated service account with the necessary impersonation or application permissions in Exchange or Office 365 is required so the connector can read and process calendar data for room and resource mailboxes. Option C is not required because Unified Communications Manager is relevant to Hybrid Calling/Webex Calling integrations, not to the calendar service itself. Option D is not required because a public PSTN trunk is only needed for telephony/PSTN connectivity, which is unrelated to calendar processing.

Answer

A Cisco Unified Communications Manager cluster.

Answer

A public PSTN trunk.

Question 5

Which TWO of the following items can be monitored in the Webex Control Hub under the 'Hybrid' tab? (Choose two)

Accepted Answer

Connector status (up/down).. In Webex Control Hub, the Hybrid tab is dedicated to monitoring the health and status of on-premises hybrid services such as Calendar, Call, Message, and Directory connectors. Option C (Connector status (up/down)) is correct because Control Hub displays the live operational state of each deployed hybrid connector, showing whether it is up, down, or degraded. Option D (Connection health metrics) is correct because the Hybrid tab surfaces health metrics for the connector-to-cloud connections, including latency, availability, and alerting on connectivity issues. Option A (Physical desk phone inventory) is not monitored there; device inventory is found under the Devices tab. Option B (PSTN usage minutes) is reported under Calling/Analytics, not the Hybrid tab. Option E (User password history) is an identity/security setting in Control Hub's user management, not a hybrid monitoring item.

Answer

Physical desk phone inventory.

Answer

PSTN usage minutes.

Answer

User password history.

Question 6

Which THREE of the following troubleshooting steps should be performed if a Webex Hybrid connector is showing 'Down' in Control Hub? (Choose three)

Accepted Answer

Restart the Management Service on the Expressway-C.. Option A is correct because restarting the Management Service on the Expressway-C (via the CLI command 'xstatus' or the web UI service restart) re-establishes the connector's registration and signaling channel to Control Hub when the service has hung or lost its tunnel. Option B is correct because the Expressway-C connector requires outbound TCP 443 (HTTPS) connectivity to the Webex Cloud endpoints; if firewall rules or proxy settings block this, the connector status will show Down. Option E is correct because the local diagnostic logs on the Expressway-C (accessible via 'xcommand Log' or the web interface diagnostics) contain the specific error codes and connection failures needed to pinpoint why the connector cannot reach the cloud. Option C is not relevant because re-provisioning a domain controller addresses Active Directory issues, not the Expressway-C's cloud connector tunnel. Option D is not relevant because upgrading the CUCM cluster software does not resolve a Webex Hybrid connector that is Down on the Expressway-C.

Answer

Re-provision the Active Directory domain controller.

Answer

Upgrade the CUCM cluster software.

Question 7

Which TWO of the following features are supported by the Webex Hybrid Message Service? (Choose two)

Accepted Answer

Instant message exchange.. Option B (Instant message exchange) is correct because the Webex Hybrid Message Service connects on-premises Cisco Unified Communications Manager IM and Presence (or Jabber) deployments to the Webex cloud, enabling users to exchange instant messages between the on-premises environment and Webex App users. Option D (Presence status synchronization) is correct because the same hybrid message connector synchronizes presence status between the on-premises IM and Presence service and the Webex cloud, so availability states remain consistent across both environments. Option A (Voicemail transcription) is not part of Hybrid Message Service; voicemail and transcription relate to Webex Hybrid Calling/Voice or Unity Connection voicemail services. Option C (Email synchronization) is unrelated, as Webex Hybrid Message Service handles IM and presence, not email. Option E (Web-based meeting recording) belongs to Webex Meetings functionality, not the Hybrid Message Service.

Answer

Voicemail transcription.

Answer

Email synchronization.

Answer

Web-based meeting recording.

Question 8

Which TWO of the following are necessary to configure 'Hybrid Call Service' for Cisco Unified Communications Manager? (Choose two)

Accepted Answer

Cisco Unified Communications Manager configuration.. Option A is correct because Hybrid Call Service requires configuration on the on-premises Cisco Unified Communications Manager itself, including setting up the Webex Calling/Webex app integration, the Expressway-C as a registered collaboration edge node, and the appropriate SIP trunk and routing configuration to connect CUCM to the Webex cloud. Option D is correct because the Expressway-C must be registered to Webex (via the Webex Edge/Cloud Connected UC or Hybrid Services connector) to establish the secure tunnel between the on-premises CUCM environment and the Webex cloud, which is the core transport for Hybrid Call Service. Option B is incorrect because Hybrid Call Service does not require a separate Webex Edge server; the Expressway-C handles the edge connectivity. Option C is incorrect because an on-premises PSTN gateway is not mandatory for Hybrid Call Service, since PSTN connectivity can be provided through Webex Calling or existing CUCM gateways depending on the deployment. Option E is incorrect because a dedicated public IP address for CUCM is not required; CUCM remains internal and the Expressway-C provides the secure edge connectivity to Webex.

Answer

A separate Webex Edge server.

Answer

An on-premises PSTN gateway.

Answer

A dedicated public IP address for the CUCM.

Question 9

You are implementing Webex Calling with a Local Gateway. The requirement is to maintain internal dial plan transparency for existing extension-to-extension dialing. What must you configure?

Accepted Answer

Location-based routing and dial plan normalization. Location-based routing and dial plan normalization are essential for maintaining internal dial plan transparency. Location-based routing ensures that calls are routed according to the user's location, and dial plan normalization translates dialed digits into a format that the local gateway can process, preserving extension-to-extension dialing.

Answer

Global Dial Plan Replication

Answer

Directory sync override

Answer

PSTN overflow routing

Question 10

Which service allows a user to access Webex Meeting features from a standards-based SIP video endpoint?

Accepted Answer

Hybrid Video Mesh. Webex Hybrid Video Mesh or the SIP Registration service allows SIP endpoints to join Webex meetings seamlessly.

Answer

Webex Calling

Answer

Hybrid Calendar Service

Answer

Hybrid Directory Service

Question 11

You are troubleshooting high latency for Webex media. Which tool in Control Hub provides the best visibility into the path taken by the media packets?

Accepted Answer

Calling Quality of Service (QoS) Dashboard. The Calling Quality of Service (QoS) Dashboard in Control Hub provides detailed media path visibility, including hop-by-hop network segments and their associated latency, jitter, and packet loss. It correlates data from Webex media nodes and endpoints to show the actual path taken by media packets, enabling rapid identification of problematic network segments. This is specifically designed for troubleshooting real-time media quality issues like high latency.

Answer

Device logs

Answer

Packet Capture (PCAP) from the cloud

Answer

Network Analysis Tool

Question 12

Which THREE components are involved in the Webex Hybrid Media Service architecture?

Accepted Answer

Expressway-C. The Webex Hybrid Media Service architecture relies on Expressway-C (option B), which acts as the on-premises connector that registers to the Webex cloud and brokers media between the enterprise and Webex services. Webex Control Hub (option C) is the management plane where the Hybrid Media Service is enabled, configured, and monitored, including assigning the service to specific Expressway-C connectors. Webex Media Node (option E) is the on-premises media processing component that handles the actual media (audio/video) locally for Hybrid Media Service calls, reducing traffic to the cloud. The other options are not part of this architecture: Cloud PSTN Gateway (A) relates to cloud-connected PSTN calling rather than hybrid media processing, and CUCM Media Resource Group (D) is a Cisco Unified Communications Manager construct for on-premises media resource selection, not a Webex Hybrid Media Service component.

Answer

Cloud PSTN Gateway

Answer

CUCM Media Resource Group

Question 13

Which of the following is a prerequisite for deploying Webex Hybrid Data Security?

Accepted Answer

A minimum of three HDS nodes for high availability. Hybrid Data Security requires specific network connectivity and security infrastructure to ensure that the HDS nodes can communicate securely with the Webex cloud.

Answer

An on-premises CUCM cluster version 12.5 or higher

Answer

A Webex Calling Pro license

Answer

Direct fiber connection to a Webex data center

Question 14

Which TWO of the following are valid methods for connecting on-premises PSTN to Webex Calling?

Accepted Answer

Local Gateway. Local Gateway (D) is correct because it is a premises-based Cisco IOS-XE gateway (e.g., CUBE) that connects on-premises PSTN circuits to Webex Calling via a registration-based SIP trunk to the Webex Calling cloud. Cloud Connected PSTN (E) is correct because it lets a service provider deliver PSTN directly to Webex Calling in the cloud, with no on-premises gateway required. Direct SIP to CUCM (A) is not a Webex Calling PSTN option since CUCM is a separate call-control platform, not a Webex Calling PSTN connection method. H.323 Trunking (B) is not supported for Webex Calling PSTN connectivity, which uses SIP. Webex Edge for Calling (C) is a hybrid service for integrating existing CUCM/on-premises calling with Webex Calling, not a method for connecting on-premises PSTN.

Answer

Direct SIP to CUCM

Answer

H.323 Trunking

Answer

Webex Edge for Calling

Question 15

Which TWO features are included in the Webex Control Hub 'Troubleshooting' tool?

Accepted Answer

Historical call quality data analysis. Option A (Historical call quality data analysis) is correct because the Webex Control Hub Troubleshooting tool lets administrators retrieve and review past call-quality metrics (such as jitter, latency, packet loss, and MOS scores) for completed calls, which is essential for diagnosing intermittent or already-ended call issues. Option B (Real-time call participant monitoring) is correct because the same Troubleshooting tool provides live visibility into ongoing sessions, showing active participants and their current media statistics so admins can intervene during a call in progress. Option C (Direct router configuration) is not included, since Control Hub is a cloud management portal and does not push configuration to on-premises routers. Option D (Automated firmware deployment) is not part of Troubleshooting; device firmware management is handled through separate device management features, not the troubleshooting workflow. Option E (User password reset) is not a Troubleshooting tool function, as identity and password operations are handled via user management or directory integration, not call diagnostics.

Answer

Direct router configuration

Answer

Automated firmware deployment

Answer

User password reset
