When changes in daylight savings occur, the timezone must be changed at both the user group level and the system partition level in order to adjust the start and end times of shifts. This can be done by logging into the Cisco Unified Contact Center Enterprise (UCCE) Administration Portal and navigating to the User Group Management and System Partition Management menus [1], respectively.

C. Change the timezone at the user group level: The timezone for all the agents under the user group level should be changed to match the new time after daylight savings. This will ensure that the agents are working according to the new time zone and that their activity is recorded correctly in the system.

D. Change the timezone at the system partition level: The timezone at the system partition level should be changed to match the new time after daylight savings. This will ensure that the system is configured according to the new time zone and that all the activity is recorded in the correct time.

C. SS0 is not enabled by default; configuration is necessary. Single Sign-On (SSO) is not enabled by default in Cisco ECE, and configuration is necessary in order to set it up. This configuration involves setting up SSO on the Cisco ECE and Cisco Unified CCE side and configuring the SSO settings in Cisco Finesse.

D. SS0 allows agents, supervisors, and administrators to provide CCE credentials once and be authenticated across multiple disparate applications. This feature allows agents to sign on once and access all the applications that they need, such as Cisco Finesse, Cisco ECE, and other web-based applications, without having to sign in multiple times.

A chat entry point is a page or link that customers can use to access the chat service. Help links on websites can be configured to point to the same entry point, so customers will see the same interface regardless of which link they use to access the service. This makes it easier for customers to find the help they need, as all the help links will point them to the same entry point.

The maximum permissible one-way network delay between Unified CCE (Cisco Unified Contact Center Enterprise) servers and Enterprise Chat and Email (ECE) servers is 240 milliseconds. This delay is necessary for the servers to communicate with each other without any latency issues.
