CLCOR 350-801 v2.0 is Cisco’s Collaboration core exam. Passing earns the Collaboration Core Specialist credential. For CCNP Collaboration, add a concentration exam; CCIE Collaboration instead requires its separate practical exam. This guide maps the six core domains and works through a signaling-versus-media example.
What the 350-801 CLCOR exam certifies
CLCOR v2.0 is Cisco's core Collaboration exam. Passing it earns the Cisco Certified Specialist - Collaboration Core credential and fulfills the core exam requirement for the CCNP Collaboration and CCIE Collaboration certifications.
Use the core blueprint to check breadth and the required objective verbs. It covers on-premises call control, cloud and hybrid services, endpoints, gateways, infrastructure, media and QoS. A specialist’s experience in one part does not establish coverage of the other domains.

Exam logistics at a glance
Cisco lists 120 minutes, $400 USD and English delivery. Confirm the final booking cost and appointment requirements.
The current Learning Network topic page lists performance-based, multiple-choice and drag-and-drop questions. Use Cisco’s exam tutorial to become familiar with the interface.
The retrieved sources do not establish a fixed question count, lab order or numerical passing score. Use the objective list to plan preparation.

Prerequisites and the CCNP Collaboration path
No formal prerequisite certification is listed. CCNP requires the core plus a concentration; CCIE requires the core plus its practical exam.
Cisco lists CLACC, CLHCT and CLCCE as CCNP Collaboration concentrations. Check the current descriptions against the work you want to develop; the choice does not change the CLCOR core objectives.
The separate CCIE Collaboration practical exam is currently v3.1 and lasts eight hours. Core study alone does not cover that entire practical assessment.
Cisco lists three-year certification validity and recertification options. Review the current exam-pass and renewal rules when planning your path.

The six testing areas and their weights
The exam covers six domains: Infrastructure and Design (15%), Protocols and Endpoints (10%), On-Premises Call Control (30%), Voice Gateways and Session Border Controllers (10%), Cloud and Hybrid Services (25%), and Media and QoS (10%).
Use the full v2.0 document for task-level coverage. On-Premises Call Control and Cloud and Hybrid Services together carry 55% of the blueprint, but all six domains need attention.
| Domain | Weight | What it covers |
|---|---|---|
| Infrastructure and Design | 15% | Deployment models, sizing, resilience, security and network services |
| Protocols and Endpoints | 10% | On-premises/cloud endpoint deployment, SIP/SDP, DTMF and registration; specified exclusions include Skinny and Jabber |
| On-Premises Call Control | 30% | UCM routing and toll-fraud prevention, dial-plan objects, APIs, Unity Connection and user management |
| Voice Gateways and Session Border Controllers | 10% | IOS XE gateway/SBC configuration, dial plans and media resources; H.323 dial peers are excluded |
| Cloud and Hybrid Services | 25% | Webex calling/meetings/messaging, cloud APIs and webhooks, Control Hub, Cloud Connected UC and hybrid services |
| Media and QoS | 10% | Audio/video troubleshooting, wired and wireless QoS, trust boundaries and LLQ configuration |

Why the v2.0 edition matters for your study material
Compare older material with the current objectives before deciding what to keep or replace.
Build a gap map with one row per objective. Record the chapter or exercise that covers it, the required verb and any missing practice. A book’s age or table of contents alone does not establish complete coverage.
Pay particular attention to Cloud and Hybrid Services, at 25%, and the explicitly excluded endpoint and gateway technologies. Wireless QoS remains in CLCOR’s Media and QoS scope; do not import ENCOR’s removed-wireless rule into this exam.
Worked exercise: separate signaling and media evidence
Successful call setup does not by itself demonstrate media delivery. Identify what the observations prove before choosing a cause.
RFC 3261 describes SIP as a signaling protocol for establishing, changing and ending sessions. RFC 3550 describes RTP’s transport functions for real-time data and states that it does not guarantee quality of service.
The CLCOR blueprint includes both SIP troubleshooting and media-quality problems. This original exercise supplies the evidence; it does not require guessing a product-specific command or fault.
Practice exercise
In a controlled two-endpoint lab call with direct media, logs verify successful SIP setup. The agreed media addresses, ports and codec have been checked. Synchronized, validated captures with no capture loss show A’s RTP packets leaving A and arriving at B. They also show B’s RTP packets leaving B toward A’s correct address and port, but none arriving at A’s monitored inbound interface. What does this establish, what should you investigate next, and does it prove that a firewall caused the problem?
Show answer
The observed reverse media path from B to A is not delivering the captured packets to A’s monitored interface. Investigate that path and gather evidence at intermediate points. The captures do not identify a firewall as the cause.
The call-setup evidence concerns signaling, while the packet captures concern media transport. A-to-B delivery does not prove B-to-A delivery. The stated capture checks make the missing reverse packets a meaningful observation, but routing, translation, filtering or another path fault cannot be distinguished without more evidence. Compare relevant path and device observations to locate the loss before choosing a corrective change. Do not generalize from this call to every signaling function or claim that one-way audio always has one cause.

A preparation sequence you can adapt
Use the objective list to connect study resources, lab practice and error review.
Mark each objective by its required skill, then record what you can demonstrate. Use the larger domain weights and your weak topics together to decide the next study block.
Cisco lists guided learning, instructor-led training and community resources. Check their current coverage before purchasing. In your own lab, record the expected result, introduce one relevant change and verify your diagnosis against the observations.
