A SIP proxy server is a component of a SIP network that handles the setup and termination of calls between SIP devices. It also performs functions such as registration, authorization, network access control, and network security. Some of the functions of a SIP proxy server are:

• Centralizes dial plans: A SIP proxy server can centralize the dial plans for a SIP network, meaning that it can translate and route calls based on a unified set of rules and policies. This simplifies the administration and management of the SIP network and ensures consistent call routing across different devices and locations.
• Helps to centralize the administration and call control: A SIP proxy server can also help to centralize the administration and call control of a SIP network, meaning that it can provide a single point of contact and configuration for all the SIP devices and endpoints. This reduces the complexity and overhead of maintaining multiple SIP servers and devices and allows for easier monitoring and troubleshooting of the SIP network.

 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.

The Single Pane of Glass (SPOG) is the web-based administrative interface that should be deployed to provide a unified and simplified view of the Unified CCE system, even though Unified CCE provides Configuration Manager as the legacy User Interface for administrators1. The SPOG is also known as the CCE Web Administration or the Unified CCE Administration console, and it allows administrators to configure and manage various Unified CCE features and settings, such as agents, attributes, precision queues, bucket intervals, media routing domains, license, bulk jobs, deployment type, system information, single sign-on, context service, and contact center AI23.

The other options are incorrect because:

• A: WebSetup is not a web-based administrative interface, but rather a tool that is used to install and configure the web setup components, such as the web setup database, the web setup service, and the web setup client, on the Unified CCE servers. WebSetup is used to perform initial configuration tasks, such as setting the deployment type, the instance name, the security mode, the license server, and the LDAP directory4.
• B: Contact Centre Management Portal (CCMP) is not a web-based administrative interface for Unified CCE, but rather a separate product that provides a web-based interface for managing Cisco Unified Contact Center Express (UCCX) and Cisco Unified IP Interactive Voice Response (IP IVR) systems. CCMP allows administrators to perform tasks such as creating and modifying scripts, applications, triggers, teams, skills, and CSQs, as well as monitoring and reporting on the system performance and agent activity5.
• C: LDAP Plugin is not a web-based administrative interface, but rather a component that enables Unified CCE to integrate with an external LDAP directory, such as Microsoft Active Directory, for user authentication and authorization. LDAP Plugin allows Unified CCE to synchronize user data from the LDAP directory and assign roles and permissions to the users based on their LDAP group membership2.
