Describing the Test Domains
- QoS
This section assesses the candidates' knowledge of common problems associated with poor video and voice quality such as jitter, packet loss, and latency. Also, applicants need to know QoS requirements for video and voice application types and understand the role of different DiffServ values such as EF, CS4, CS3, and AF41 as they relate to collaboration. The next topics covered include the importance of QoS trust boundaries, class models, location-based CAC bandwidth requirements, and setting up as well as verifying LLQ.
- Design and infrastructure
Here, the instructors will want to know if you can describe the key components of design when it comes to Cisco Collaboration architecture. They include high availability, bandwidth, sizing, licensing, security, QoS, disaster recovery, and dial plan. Also, the candidates should show their knowledge of the crucial elements that Cisco Collaboration technologies like SNMP and DNS, the purpose of of edge devices within the Cisco Collaboration architecture, and skills in troubleshooting DNS, NTP, and LDAP integration.
- Call Control
This module of the exam outline emphasizes four major skills including those associated with the Mobile and Remote Access (MRA), Cisco Unified Communications Manager digit analysis process, and the implementation of toll fraud prevention. In addition, one should be skilled in the configuration of globalized call routing within a Cisco Unified CM.
- Collaboration Applications
This domain will mostly focus on the setting up the SIP integration options to call control, configuration of MWI and Unity Connection Mailbox, and description of call handlers. It also covers the deployment of Cisco jabber on-premises as well as Cisco Unified IM&P protocols and high avilability.
