Which option can be configured while installing Cisco Unified CCX on Cisco UCS servers?

 The option that can be configured while installing Cisco Unified CCX on Cisco UCS servers is the NTP server. The NTP server is used to synchronize the time between the Unified CCX nodes and other components such as CUCM, LDAP, and SMTP servers. The NTP server must be configured on the first node before installing the second node, otherwise the installation will fail. The NTP server can be configured in the basic configuration information that is required during installation. The DNS server, the SMTP server, and the CUCM server are not configured during the installation, but they can be configured later in the Unified CCX Administration web interface. References := Deploying Cisco Unified Contact Center Express (UCCXD) v6.0 > Module 2: Implementing Cisco Unified Contact Center Express > Lesson 2: Installing Cisco Unified Contact Center Express > Topic 2.2: Installing Unified CCX1
