Cisco Gateway Gatekeeper Exam 642-452... Continue Below To CCVP Exam Information and Cisco Articles. The real Cisco CCVP 642-452 GWGK Exam has a duration of 90 minutes and 55 -65 questions to complete.
The Gateway Gatekeeper GWGK 642-452 exam assesses the knowledge of the Systems Engineer on the implementation of Cisco gateways and gatekeepers to integrate a VoIP network to both PSTN and TDM equipment. The Cisco GWGK 642-452 exam includes implementing dial plans and advanced gateway features such as SRST and DSP resources. The Cisco GWGK 642-452 exam also covers implementing gatekeepers and directory gatekeepers to provide hierarchical dial plan resolution and call admission control. All these objectives are designated from the Cisco.com website. Please note that exam topics and objectives may change without notice, since technologies are always changing.
