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.

 Cisco Unified Border Element (CUBE) is a session border controller that provides session control, security, interworking, and demarcation for voice and video calls between the enterprise IP network and service provider SIP trunks1. When CUBE is used with CCE and CVP, it provides the following three features:

• Silent Monitor inbound voice calls: CUBE supports the silent monitoring feature for inbound voice calls from the PSTN to the CCE agents. This feature allows supervisors to listen to the agent-customer conversations without being noticed by either party. CUBE uses the built-in-bridge (BIB) capability of the agent phone to fork the media stream and send it to the monitoring server2.
• Secure communication using flow around mode: CUBE supports secure communication using Transport Layer Security (TLS) and Secure Real-Time Transport Protocol (SRTP) for SIP signaling and media streams. CUBE can operate in flow around mode, where it terminates the TLS/SRTP sessions from the service provider and the enterprise, but does not perform any media processing or transcoding. This mode reduces the CPU load on CUBE and preserves the end-to-end media encryption3.
• Normalize SIP messages using SIP profiles: CUBE supports SIP normalization using SIP profiles, which are collections of parameters that modify the SIP messages that pass through CUBE. SIP profiles can be used to resolve interoperability issues between different SIP implementations, such as service providers, CVP, and CCE. SIP profiles can also be used to enhance the functionality of CUBE, such as adding or removing headers, modifying timers, and enabling features4.

Cisco VOS is a Linux-based operating system that runs on Cisco Unified Communications servers. It provides a common platform for various Cisco applications, such as Finesse, CUIC, CVP, and ECE. Finesse is a web-based agent and supervisor desktop solution that integrates with Cisco Unified Contact Center Enterprise (CCE) and Customer Voice Portal (CVP). CUIC is a web-based reporting and analytics solution that provides real-time and historical data for Cisco Unified CCE and CVP. CVP is a software-based solution that provides call control, voice self-service, and outbound dialing capabilities. ECE is an email and chat solution that integrates with Cisco Unified CCE and Finesse.

CUBE is a Cisco IOS software feature that provides voice and video connectivity from IP phones to the PSTN or other IP networks. CUBE supports several advanced call control and mobility services, such as:

• Element Grouping: This feature allows you to group multiple CUBE elements into a single logical entity and apply common configuration and dial plan across them. This simplifies the management and scalability of CUBE deployments.
• Time of Day Routing: This feature allows you to route calls based on the time of day, day of week, or date. You can define time periods and time schedules and associate them with dial peers or voice translation rules. This enables you to implement different call routing policies for different time slots, such as business hours, after hours, holidays, etc.
• Call Admission Control: This feature allows you to limit the number of concurrent calls on a CUBE element or a CUBE group based on the available bandwidth or the configured maximum number of calls. This prevents oversubscription of network resources and ensures the quality of service for voice and video calls.

 The keytool command that lists certificates in the cacerts file is B: keytool -list -keystore cacerts. This command will display the aliases and fingerprints of all the certificates in the cacerts file, which is the default truststore for Java applications1. The cacerts file contains the root and intermediate certificates of various certificate authorities (CAs) that are trusted by Java2.

The other options are incorrect because:

• A: keytool -list -showinfo is not a valid keytool command, as the -showinfo option does not exist. The closest option is -v or -verbose, which will display more details about each certificate, such as the owner, issuer, serial number, validity period, signature algorithm, and extensions1.
• C: keytool -list cacerts is not a complete keytool command, as it is missing the -keystore option, which is required to specify the name or path of the keystore file to be listed. Without the -keystore option, the keytool command will assume the default keystore file, which is usually named .keystore in the user’s home directory1.
• D: keytool -list -alias is also not a complete keytool command, as it is missing the value of the -alias option, which is used to specify the alias of a particular entry in the keystore file to be listed. Without the value of the -alias option, the keytool command will display an error message, such as "keytool error: java.lang.Exception: Alias does not exist"1.
