Cisco 350-801 CLCOR study plan

Cisco 350-801 CLCOR · Give each week a clear focus.

8 weeks · About 7 hours per week

Week 1

Infrastructure and Design

Diagram a multi-cluster Cisco UCM deployment showing publisher/subscriber roles, database replication, and inter-cluster trunking paths
Compare on-premises, Webex Calling cloud, and hybrid calling designs, then justify a choice for three given business scenarios
Calculate user and device licensing counts and tiers for a 500-user organization with shared devices and softphone-only users
List the design impact of DNS, NTP, DHCP options 150/66/67, and virtualization requirements on endpoint onboarding and cluster health

One-page design brief containing a labeled topology diagram plus a licensing count table for the 500-user scenario

Week 2

Compare SIP, SCCP, MGCP, and H.323 signaling on transport, default ports, and where each is typically deployed in a Cisco UCM environment
Trace an end-to-end SIP invite/offer-answer/acknowledge/teardown flow and identify which messages carry SDP
Rank G.711 a-law, G.711 mu-law, G.722, G.729, and Opus by bandwidth per call, compression type, and MOS impact
Explain RTP/RTCP port ranges and compare in-band, RFC 2833/4733, and SIP INFO DTMF delivery across codecs and trunks

Annotated SIP ladder diagram plus a codec bandwidth and MOS comparison table

Week 3

Trace a call spanning a SIP endpoint, Cisco UCM, and an SCCP gateway, labeling every signaling leg and media re-invite
Describe Cisco UCM digit analysis order of precedence and explain how urgent patterns and off-hook digit analysis change matching
Configure partitions, calling search spaces, and line/device CSS to enforce three distinct calling restrictions
Configure a SIP trunk with a region-appropriate codec preference and verify negotiation in a packet capture

Written digit-analysis walkthrough for five sample dialed strings plus a working lab SIP trunk with capture evidence

Week 4

Build route groups, route lists, and route patterns using top-down and circular distribution to meet a stated overflow requirement
Configure translation patterns, called/calling party transformations, and globalized +E.164 routing between two sites
Implement time-of-day routing and toll-fraud prevention using partitions, patterns, and class of restriction
Configure call coverage with hunt pilots, line groups, call forwarding, and shared lines for a 20-user department

Validated dial plan workbook listing 10 test numbers with expected route, transformation result, and observed result in the lab

Week 5

Identify when Cisco UCM inserts an MTP, transcoder, or conference bridge, and map resources through media resource groups and lists
Configure and register MTP, transcoder, and conference bridge resources on a lab router or DSP farm
Distinguish region codec policy from location bandwidth allocation and compute allowable calls between three location pairs
Compare ad hoc, meet-me, and rendezvous conferencing and select the correct bridge type for each scenario

Bandwidth and calls-per-location worksheet for a three-site topology with a matching media resource group configuration

Week 6

Configure unicast and multicast music on hold with the correct audio source, media resource group, and device pool assignment
Configure annunciator and verify a specific set of tones and messages plays at the expected points in a call
Design device pools, regions, and locations for a multi-site deployment that satisfies a given bandwidth budget
Verify media resource selection using SDL traces and confirm failover behavior when a media resource becomes unavailable

Trace-verified media resource test matrix showing resource chosen, fallback path, and capture or trace evidence per test case

Week 7

Compare on-premises auto-registration, bulk administration, self-provisioning, and VPN onboarding and match each to an endpoint population
Configure phone button templates, softkey templates, device profiles, and universal device templates for a standardized rollout
Explain CAPF, locally significant certificates, and phone trust lists, and describe the order of secure onboarding steps
Configure an LDAP-synced or local end user with extension mobility and verify login behavior across two devices

Bulk administration CSV template set plus a post-import verification checklist with expected versus observed results

Week 8

Re-drill the two lowest-scoring domains from prior practice sets until each error is traced to a root cause
Recalculate codec bandwidth, location call counts, and digit analysis outcomes for ten mixed problems without notes
Complete two timed 60-question practice sets under exam conditions and log every missed item by domain

Error log with root-cause notes for every missed question and two timed practice scores at or above 85 percent

Week 2: Explain SIP, SCCP, MGCP, and codec tradeoffs aloud without notes and score at least 80 percent on a 20-question Domain 2 self-quiz

Week 4: Route all 10 test dial strings correctly in the lab and score at least 75 percent on a Domain 4 practice set

Week 6: Produce correct bandwidth and calls-per-location figures for all three sites and score at least 75 percent on a Domain 5 practice set

Week 8: Complete two timed practice exams at or above 85 percent overall with no single domain below 70 percent
