Question 1 of 30

A company is experiencing issues with the registration of its Cisco collaboration devices. The network administrator notices that several devices are failing to register with the Cisco Unified Communications Manager (CUCM). After checking the network configuration, the administrator finds that the devices are on a different VLAN than the CUCM server. What is the most likely cause of the registration issue, and how should the administrator address it?

The devices are unable to reach the CUCM due to VLAN segmentation, requiring proper routing or VLAN configuration.

The devices are using outdated firmware that is incompatible with the CUCM version.

The CUCM server is overloaded and cannot handle additional registration requests from the devices.

The devices are configured with incorrect SIP settings that prevent them from registering.
