Cisco Collaboration Cloud and Edge Solutions & Cloud and Edge Networking Fundamentals
Map the Cisco Collaboration cloud and edge architecture components (Cisco Unified Communications Manager Cloud, Webex Calling, Expressway, CUBE, and Edge) to their functions and deployment models.
Describe how cloud and edge networking fundamentals (SD-WAN, NAT, firewall traversal, QoS, and DNS) affect collaboration call flows.
Compare cloud-connected, on-premises, and hybrid collaboration topologies and list two trade-offs for each.
Create a one-page topology diagram that labels the call control and media paths between cloud, edge, and on-premises endpoints.
Your checkpoint
A labeled topology diagram and a 300-word comparison table of cloud, on-premises, and hybrid collaboration models.
Cisco Collaboration Cloud and Edge Solutions & Cloud and Edge Networking Fundamentals
Configure a basic Expressway traversal zone and explain how it enables firewall traversal for collaboration traffic.
Explain the role of CUBE in cloud and edge connectivity, including SIP trunking and media handling.
Identify the networking requirements (ports, protocols, MTU, QoS markings) for a Webex Calling or UCM Cloud deployment.
Troubleshoot a simulated edge registration failure using logs and configuration checks.
Your checkpoint
A configuration checklist and a troubleshooting log documenting the resolution of the simulated edge registration failure.
Cisco Collaboration Cloud and Edge Solutions & Cloud and Edge Networking Fundamentals
Design a hybrid call routing scenario that uses both on-premises and cloud call control.
Evaluate bandwidth and QoS requirements for voice and video across a WAN or SD-WAN connection.
Explain the security implications of exposing edge services to the internet and list mitigation steps.
Summarize how DNS, certificates, and NTP support secure cloud and edge collaboration services.
Your checkpoint
A design document for a hybrid call routing scenario with bandwidth calculations and a security mitigation list.
Call Control and Dial Plan Design
Build a dial plan that includes site codes, steering digits, and translation patterns for a multi-site deployment.
Apply called and calling party transformations to normalize numbers between on-premises and cloud systems.
Configure route groups, route lists, and route patterns to implement least-cost and failover routing.
Test the dial plan with at least five call scenarios and document the expected and observed results.
Your checkpoint
A working dial plan configuration export and a test matrix with five call scenarios showing expected versus observed results.
Call Control and Dial Plan Design
Design a numbering plan that accommodates E.164, national, and internal extensions without overlap.
Implement globalized call routing with +E.164 numbers and device-level transformations.
Explain how partitions and calling search spaces enforce call admission and class of service.
Troubleshoot a call routing failure using DNA, translation pattern analysis, and route plan reports.
Your checkpoint
A revised numbering and dial plan document with partition/CSS design and a troubleshooting walkthrough for one failed call.
Security, Management, and Troubleshooting
Configure certificate-based security for SIP trunks and edge connections, including certificate trust and TLS.
Apply security hardening to collaboration components: disable unused services, enforce strong authentication, and restrict management access.
Set up a logging and monitoring approach for collaboration services using syslog, SNMP, and CDR/CMR.
Describe how to manage cloud services using APIs and administrative portals.
Your checkpoint
A security configuration checklist and a monitoring plan that lists the logs, alerts, and metrics you would collect.
Security, Management, and Troubleshooting
Diagnose a media quality issue using RTMT, packet captures, and QoS statistics.
Troubleshoot a SIP trunk or edge connectivity failure by analyzing SIP messages and logs.
Use Cisco Collaboration tools (such as Webex Control Hub analytics or UCM reports) to identify performance trends.
Document a root-cause analysis for two simulated incidents.
Your checkpoint
Two root-cause analysis reports, each with a timeline, evidence, root cause, and remediation steps.
Cisco Collaboration Cloud and Edge Solutions & Call Control and Dial Plan Design & Security, Management, and Troubleshooting
Review all domains using a practice exam or question set and score at least 80%.
Revisit weak areas identified by the practice exam and create a one-page summary for each.
Walk through an end-to-end call flow from a cloud endpoint to an on-premises endpoint, listing each component and protocol involved.
Finalize a personal exam-day checklist covering time management and key troubleshooting commands.
Your checkpoint
A practice exam score report with a remediation log and a one-page end-to-end call flow summary.
Milestones
Week 2: Can explain and diagram the traversal path for a call from a remote endpoint through Expressway to an on-premises UCM, including the protocols used at each hop.
Week 4: Can build and test a multi-site dial plan with site codes and failover routing, and correctly predict the route for three sample numbers.
Week 6: Can secure a SIP trunk with TLS and certificate trust, and list the steps to harden a collaboration node.
Week 8: Scores at least 80% on a timed practice exam and can explain the root cause of two simulated incidents without notes.
