500-444 Exam Dumps : Cisco Contact Center Enterprise Implementation and Troubleshooting

External voice DNs are sourced from CUCM in a CCE Dial Plan. External voice DNs are the DNs that are not associated with any CCE device, such as agent phones, VRU peripherals, or gateways. They are used to route calls to destinations outside the CCE network, such as PSTN numbers, voicemail, or other PBXs. CUCM is responsible for provisioning and managing these DNs and assigning them to the appropriate devices or trunks. CVP can also use external voice DNs to send calls to CUCM for further routing or treatment.

The CLI command that manages the Java Keystore Certificate in Windows CCE servers is keytool. Keytool is a utility that is included in the Java Runtime Environment (JRE) and allows you to create, import, export, list, and delete certificates, keys, and keystores. A keystore is a repository of security certificates that can be used for SSL/TLS communication. The Java Keystore Certificate is the default keystore that is used by the Java applications running on the Windows CCE servers, such as the Web Setup tool, the Diagnostic Framework Portico, and the Unified Intelligence Center12. To use keytool, you need to open a command prompt window and navigate to the JRE bin directory, which is typically located at C:\Program Files\Java\jre\bin. Then, you can use the keytool command with various options and parameters to perform the desired operations on the Java Keystore Certificate34. References: Security Guide for Cisco Unified ICM/Contact Center Enterprise, Release 12.5 (1) and 12.5 (2)1, Implement CA Signed Certificates in a CCE 12.6 Solution2, SSL Certificate Installation - Java Based Web Servers - DigiCert3, Keytool - Oracle Help Center4.

 The deployment team is responsible for ensuring that servers designated for use by CCE VMs meet the requirements, including but not limited to Storage System Performance and IOPS (Input/Output Operations Per Second) Requirements. The deployment team is the group of engineers who install, configure, and test the CCE solution at the customer site. They must follow the design specifications and guidelines provided by the design team, and verify that the hardware and software components are compatible and meet the performance and capacity requirements. The deployment team must also ensure that the CCE VMs are deployed on the appropriate servers and have the correct network and storage configurations1. References: Troubleshooting Cisco Contact Center Enterprise (CCET) course outline2, Virtualization for Cisco Packaged CCE Release 11.6(x)1.
