500-052 Exam Dumps : Deploying Cisco Unified Contact Center Express

 The maximum round-trip time (RTT) between Cisco Unified CCX servers in a WAN deployment is 80 ms. This is the network requirement for deploying Unified CCX high availability over WAN, which provides site redundancy. The RTT is the time it takes for a packet to travel from one node to another and back. If the RTT exceeds 80 ms, the Unified CCX servers may not be able to communicate properly and failover may occur. The RTT can be verified by using an extended ping command on the network device closest to the Unified CCX servers, such as the access switch. The ping command should set the Layer 3 type of service (ToS) bits to ensure that the packet is sent on the same QoS-enabled path as the WAN traffic. References := Solution Design Guide for Cisco Unified Contact Center Express, Release 12.5 (1) SU2, page 10-2. Solution Design Guide for Cisco Unified Contact Center Express, Release 11.5 (1), page 10-2.

The Cisco Agent Desktop (CAD) and the Cisco Supervisor Desktop (CSD) can be installed with two languages each. The languages are selected during the installation process and can be changed later by running the Postinstall.exe utility. The CAD and the CSD can have different languages installed, as long as they are supported by the Cisco Unified Contact Center Express (UCCX) system. The supported languages are listed in the Cisco Unified Contact Center Express Software and Hardware Compatibility Guide. References: Cisco Unified Contact Center Express Installation and Upgrade Guide, Release 12.5(1) - Install Cisco Agent Desktop, Cisco Unified Contact Center Express Installation and Upgrade Guide, Release 12.5(1) - Install Cisco Supervisor Desktop

According to the Cisco Unified Contact Center Express Design Guide, Release 8.0(1), the maximum number of CTI ports that can be supported by a Cisco Unified Contact Center Express 8.0 Standard deployment is 300. This is the same as the maximum number of IVR ports that can be supported by the Standard deployment. The CTI ports are used to route calls to agents or to play prompts and collect caller input. The number of CTI ports depends on the number of concurrent calls that the system needs to handle and the call flow design. The Standard deployment supports up to 150 agents and 300 IVR ports or CTI ports. References := Cisco Unified Contact Center Express Design Guide, Release 8.0(1), page 2-7.
