In a Cisco Unified Communications Manager (CUCM) environment, a network administrator is tasked with configuring user accounts for a new team of remote employees. Each user requires a unique extension, and the administrator must ensure that the extensions do not overlap with existing users. The current user extensions range from 1000 to 1099. The administrator decides to assign extensions starting from 1100. Additionally, the administrator needs to configure user groups and assign specific roles to these users, ensuring that they have access to the necessary features for remote collaboration. If the administrator creates 10 user accounts and assigns them to a group that has permissions for video conferencing and call forwarding, what is the total number of unique extensions that will be utilized after this configuration?
