An automated deferred sync job is a process that synchronizes the configuration data between the Unified CCE Administration and the CVP servers. An automated deferred sync job runs on the Principal AW machine, which is the primary Administration and Data Server (ADS) in the Packaged CCE deployment. The Principal AW machine initiates the sync job every 15 minutes by default, or whenever a configuration change is made in the Unified CCE Administration. The sync job sends the configuration data to the CVP servers using the REST API. The sync job also updates the status of the CVP servers in the System and Device Sync page of the Unified CCE Administration12. References:

• Packaged CCE Administration2

Answer: D

The PCCE wizard uses the Service Account login for logins to access the appropriate server and enable interfaces, databases, and protocols. The Service Account login is an existing Active Directory user in the same domain as the Packaged CCE servers. This account is added to the Service group during the initialization of the Packaged CCE deployment type. The Service Account login has the required permissions to access the SQL Server, the Organizational Units, and the Security Groups for the Packaged CCE components.

A PCCE initialization under Unified CCE PG performs the following two tasks among others:

• Creates the CUCM Peripheral Gateway (PG) with the CUCM PIM. A CUCM PG is a component that communicates with the Cisco Unified Communications Manager (CUCM) to control and monitor agent phones and route calls. A CUCM PIM is a process that runs on the CUCM PG and acts as an interface between the CUCM and the CTI Server. The PCCE initialization creates the CUCM PG with the CUCM PIM and configures the required settings, such as the JTAPI username and password, the CUCM cluster ID, and the PG ID12.
• Downloads JTAPI from the Unified Communications Manager and installs it on the Unified CCE PG. JTAPI is a Java API that enables computer telephony integration (CTI) applications to interact with the CUCM. The PCCE initialization downloads the JTAPI client from the CUCM publisher and installs it on the Unified CCE PG. This allows the CUCM PIM to use JTAPI to control and monitor agent phones and route calls13.

 The URL for the VOS O/S admin page is https:// :8443/osadmin. VOS O/S admin is a web-based tool that allows you to perform various administrative tasks on the Unified CCE servers, such as managing users, certificates, services, network settings, backups, and upgrades. VOS O/S admin requires the fully qualified domain name (FQDN) of the server and the port number 8443 to access the login page. The other options are not valid URLs for the VOS O/S admin page12. References: Cisco Unified Contact Center Enterprise Installation and Upgrade Guide, Release 12.5(1)1, Cisco Unified Contact Center Enterprise Administration Guide, Release 12.5(1)2.

The correct tools to download logs for CCE troubleshooting are:

• Diagnostic framework portico: This is a web-based interface that allows you to access various diagnostic tools and logs for CCE components. You can use it to run diagnostic tests, collect logs, view system status, and troubleshoot issues1.
• Unified System CLI: This is a command-line interface that allows you to access diagnostic tools and logs for CCE components from a single point of entry. You can use it to run diagnostic tests, collect logs, view system status, and troubleshoot issues2.
• RTTEST: This is a command-line tool that allows you to monitor the real-time status of CCE components and processes. You can use it to view the state of calls, agents, peripherals, routes, and scripts3.

An enterprise-focused Session Border Controller (SBC) providing voice and video connectivity from the enterprise IP network to service provider SIP trunks is Cisco Unified Border Element (CUBE). CUBE is a Cisco IOS software application that acts as a network border element between two or more VoIP networks, providing interconnectivity, security, and transcoding1. CUBE can be deployed on Cisco Integrated Services Routers (ISRs), Cisco Aggregation Services Routers (ASRs), or Cisco Cloud Services Routers (CSRs) in the enterprise network edge1. CUBE enables enterprises to use SIP trunking services from service providers, as well as interconnect their on-premises or cloud-based unified communications systems with other SIP networks1. CUBE also supports various features such as call admission control, media flow-through or flow-around, quality of service, and media recording1.

CUCM, CVP, and DNIS are not valid options for this question. CUCM stands for Cisco Unified Communications Manager, which is a call processing system that provides call control, device management, and user administration for Cisco IP telephony and video solutions2. CVP stands for Cisco Unified Customer Voice Portal, which is an interactive voice response system that provides self-service and call routing applications for contact centers3. DNIS stands for Dialed Number Identification Service, which is a feature that identifies the number dialed by the caller and passes it to the destination device. None of these products or features act as an enterprise-focused SBC providing voice and video connectivity from the enterprise IP network to service provider SIP trunks.

Certificate Authority (CA) signed certificates are less administration in environments with many servers, such as CCE, because they are issued by a trusted third-party entity that validates the identity of the certificate owner and provides a chain of trust. CA signed certificates are more secure and reliable than self-signed certificates, which are generated by the same entity whose identity they certify and are not verified by anyone else. Self-signed certificates require manual installation and configuration on each server and client that needs to communicate with them, which can be tedious and error-prone. 3rd party signed certificates are similar to CA signed certificates, but they are issued by a commercial entity that may charge a fee for their services. Security Authority (SA) is not a valid term for a certificate issuer. References: 1, 2, 3

Microapps are small applications that run on the CVP server and provide interactive voice response (IVR) functionality. They can play prompts, collect digits, perform database lookups, and transfer calls. Microapps are defined and configured using PCCE Web Administration Manager (S.P.O.G) under the Call Settings -> IVR Settings -> Network VRU Scripts menu. Here, you can create, modify, or delete network VRU scripts that reference the microapps and specify the parameters for each microapp. You can also associate the network VRU scripts with call types and dialed numbers to invoke them in the call flow12. References: Troubleshooting Cisco Contact Center Enterprise (CCET) course outline1, Contact Center Enterprise Troubleshooting and Configuration document2.

When an agent transfers a call to another ICM Skill Group, the call should be transferred to a CTI route point that is associated with a routing client and a dialed number in the ICM configuration. This way, the ICM can route the call to the appropriate agent based on the skill group and the call context. The ICM can also maintain the end-to-end reporting context for the call, such as the original call type, the transfer reason, the transfer time, and the transfer destination. If the call is transferred to an agent IP phone, a route pattern, or a translation pattern, the ICM will lose the visibility and control of the call, and the reporting context will be broken.

 A push sync is triggered when an administrator performs any create, update, or delete operation on a specific configuration item. A push sync sends the configuration changes to all the nodes in the PCCE deployment. A push sync is also triggered when an administrator adds or removes a node from the deployment.
