CIPT1 Chapter 2 Exam Questions with Correct Answers 2024

CIPT1 Chapter 2 Exam Questions with Correct Answers 2024 CUCM: Single-Site Deployment - answerThe single-site model for CUCM consists of a CUCM cluster located at a single site, or a metropolitan-area network (MAN), with no telephony services provided over a WAN. In a single-site deployment model, all CUCM servers, applications, and DSP resources are located in the same physical location. What are the characteristics of a single-site deployment? - answer- 30,000 SCCP or SIP endpoints supported per cluster - a max of 2,100 H.323 devices or 1,100 MGCP gateways per CUCM cluster What are the guidelines and best practices when implementing the single-site model? - answer- Use high-quality G.711 or G.722 audio codecs for all endpoints. This practice eliminates the consumption of DSP resources for transcoding. - Use MGCP gateways for the PSTN if you do not require H.323 functionality. This practice simplifies the dial plan configuration. CUCM: Multisite WAN with Centralized Call Processing - answerThe multisite WAN with centralized call processing model consists of a centralized CUCM cluster that provides services for many sites and uses the IP WAN to transport IP telephony call control (SCCP/SIP/H.323/MGCP) and media (RTP) traffic between sites. What happens to remote sites using MGCP gateways if connectivity to CUCM is lost? - answerThey will drop all active PSTN calls as soon as connectivity to CUCM is lost. MGCP gateways rely on connectivity to a call agent (CUCM) to process calls. AAR - answerCentralized call processing models can take advantage of automated alternate routing (AAR) features. AAR allows CUCM to dynamically reroute a call over the PSTN if the call is denied because of limited bandwitch (call admission control). What are the guidelines and best practices when implementing the multisite WAN model with centralized call processing? - answer- a max of 2,000 locations per CUCM cluster - a max of 2,100 H.323 devices or 1,100 MGCP gateways per CUCM cluster
