Prerequisites for Onboarding Cisco Webex Devices to Control Hub
Short answer
B Upgrade all the devices to software version CE9.15 or later.
Question
Key Takeaways
The exam tests the specific software version requirement (CE9.15+) for enabling Cloud Onboarding capabilities, which is a common trap as candidates may assume licensing or connectivity are the primary barriers.
Onboarding on-premises Cisco collaboration devices to Cisco Webex Control Hub requires upgrading device software to version CE9.15 or later. Community consensus confirms this specific version as a hard prerequisite for cloud management features like hot desking and upgrades.
Expert Analysis
Why the Answer Is Correct
Cisco mandates that on-premises devices must run software version CE9.15 or later to support the Cloud Onboarding process via Control Hub. This version introduces the necessary protocols and interfaces required for the Device Connector tool to manage devices remotely. Without this upgrade, the devices cannot communicate with the Control Hub infrastructure for provisioning or management tasks.
Why the Other Options Are Wrong
Allowing HTTP traffic (Option A) is incorrect because secure HTTPS connections are required for both the Device Connector and device-to-cloud communication; HTTP is not sufficient for security standards. Configuring the Organization ID (Option C) is a step performed during or after initial onboarding setup, not a pre-requisite action before initiating the onboarding process itself. Acquiring licenses (Option D) is essential for operation but is not the technical prerequisite for the onboarding mechanism; the device must be compatible first.
Community Comment Notes
Comment [1] provides official documentation confirming CE9.15+ as the strict prerequisite. Comment [2] argues for Option D or A, suggesting broader device compatibility issues, but these arguments overlook the specific technical constraint of the Cloud Onboarding feature set which is tied to the software version. The high vote count for B indicates strong alignment with Cisco's certification logic regarding version dependencies.

Exam Strategy
Memorize specific version numbers for new features in Cisco collaboration exams. When a question asks about 'prerequisites' for a new cloud capability, look for software version updates rather than general administrative steps like licensing.

ronaie 👍 5 Answered BPrerequisites: Software version CE9.15 or later. Encrypted version of CE software. Control Hub access as a device or org admin. You need to have IP addresses, usernames, and passwords for all the devices that you want to migrate. HTTPS connectivity to your devices for the Device Connector tool.

G0y0 👍 1 Answered DIt is importan to mention that the question is not talking about in a specific device type. They could be ip phones, Telepresence devices, webex devices, desk devices, etc. so I do not think B be correct. In fact, it is necessary to allow devices to reach control hub, A must be correct, to provision and download firmware updates. However, also it is true that the devices, since they are onboarding and changing from CUCM to Control Hub, need to have a license with a Flex Plan, The caveat is that A talk about HTTP. It must be HTTPS using TLS1.2. SO I think correct answer is D. It is necessary to have licenses for each one device in general. You must verify that sufficient Webex Device licenses are available to support your devices in the cloud.
