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

 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.

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.

• Option A is correct because if one side of the ICM Logger fails, the other side can still receive historical data from both sides of the ICM Router. However, the failed side will not be able to receive any data until it is restored1.
• Option B is correct because the Peripheral Gateways (PGs) are connected to both sides of the ICM Router through the private LAN and the visible network. If the private LAN fails, the PGs can use the visible network to communicate with the active ICM Router and determine which side is the master2.
• Option D is correct because the ICM Router uses heartbeats to monitor the status of its duplex pair. If one side does not receive a heartbeat from the other side within a specified time interval, it assumes that the other side has failed and initiates a failover process3.
• Option C is incorrect because if one side of the ICM Logger fails, the impact of call processing is not limited to the corresponding side of the ICM Router. The ICM Router can still process calls using the data from the surviving ICM Logger side1.
• Option E is incorrect because there is some impact on call processing during an ICM Logger failure. For example, some historical reports may not be available, some configuration changes may not be replicated, and some call data may be lost4.
• Option F is incorrect because during an ICM Router failover, calls in progress in Cisco Unified Customer Voice Portal (CVP) are not disconnected. The CVP uses the Survivable Remote Site Telephony (SRST) feature to maintain the calls until the failover is completed5.
