Cloud And Hybrid Services practice questions

This domain covers Cisco cloud and hybrid collaboration: Webex Calling, Webex App, Hybrid Call Service Connect, Hybrid Video Mesh, and CUBE/Local Gateway integration with on-premises CUCM and PSTN providers. Questions present real deployment symptoms, such as failed PSTN INVITEs or node removal impacts, and require you to identify the correct service behavior, configuration dependency, or troubleshooting cause.

Courseiva uses original exam-style practice questions designed for learning and revision. The goal is to understand the concepts, recognise exam patterns, and improve through explanations — not memorise copied exam dumps.

What the exam tests

What to know about Cloud And Hybrid Services

Be able to trace Webex Calling and hybrid call flows across CUBE, Local Gateway, CUCM, and Webex App. The most important thing is correctly identifying whether a failure is signaling, routing, licensing, or service-specific before choosing the fix.

Webex Calling Local Gateway and CUBE SIP signaling, including 403 Forbidden causes

Hybrid Call Service Connect call routing between Webex App and on-premises CUCM

Hybrid Video Mesh cluster node removal impact on active meetings

Webex Calling app versus Webex app calling capability differences

Watch out for

Common Cloud And Hybrid Services exam traps

▸Assuming a 403 Forbidden from CUBE is always a PSTN provider problem instead of a local dial peer or translation-rule mismatch.
▸Believing removing a Video Mesh node is transparent; active meetings hosted on that node are affected.
▸Confusing Webex Calling app and Webex app capabilities; the calling license and deployment mode determine what is available.

Which TWO steps are required to successfully deploy the Webex Hybrid Calendar service with Microsoft Exchange?

Trap 1: Configure an H.323 gatekeeper

H.323 is not used for calendar service integration.

Trap 2: Enable Webex Meetings on the local CUCM

Meetings integration is independent of the hybrid calendar.

Trap 3: Disable Active Directory integration

AD integration is generally required for proper identity mapping.

A
Create an impersonation role in Exchange
Impersonation allows the connector to access user calendars.
B
Configure an H.323 gatekeeper
Why it fails: H.323 is not used for calendar service integration.
C
Enable Webex Meetings on the local CUCM
Why it fails: Meetings integration is independent of the hybrid calendar.
D
Disable Active Directory integration
Why it fails: AD integration is generally required for proper identity mapping.
E
Deploy the Calendar Connector on a Virtual Machine
The connector node must be hosted on-premises or in a virtual environment.
