- On-Premises Call Control is 30% of the exam - CUCM call routing must be second nature.
- Cloud and Hybrid Services is 25% - know Webex Calling, Control Hub, and cloud APIs cold.
- Exam is 120 minutes, US$400 plus tax, closed-book, on the v2.0 blueprint effective February 3, 2026.
- After a fail, you wait five calendar days (starting the next day) before you can retest.
Exam Snapshot: The Numbers You Need
Before you touch a single practice question, memorize the operational facts. These are the details that trip up otherwise well-prepared candidates on exam day - not because the material is hard, but because logistics were never reviewed.

Domain Breakdown at a Glance
The exam blueprint has six domains, and their weights should directly drive how you allocate study hours. Two domains - On-Premises Call Control and Cloud and Hybrid Services - make up 55% of the exam by themselves.
| Domain | Weight |
|---|---|
| Domain 1: Infrastructure and Design | 15% |
| Domain 2: Protocols and Endpoints | 10% |
| Domain 3: On-Premises Call Control | 30% |
| Domain 4: Voice Gateways and Session Border Controllers | 10% |
| Domain 5: Cloud and Hybrid Services | 25% |
| Domain 6: Media and QoS | 10% |
If you want the long-form treatment of each domain - subtopics, sample scenarios, and study angle - the CLCOR Exam Domains 2026 guide covers all six in depth. This cheat sheet is deliberately compressed for last-mile review.
On-Premises Call Control Cheat Sheet
At 30% of the exam, On-Premises Call Control is the single heaviest domain. Most of it centers on Cisco Unified Communications Manager (CUCM) call routing logic and Cisco Unity Connection.
Domain 3: On-Premises Call Control
Candidates must understand how CUCM decides what happens to a call from dial-plan entry to endpoint delivery, plus voicemail integration behavior.
- Route patterns, route groups, route lists, and translation patterns - order of operations matters
- Calling search spaces and partitions, and how they restrict or permit call routing
- Digit analysis and how CUCM selects the best-matching pattern
- Unity Connection call handling, voicemail integration, and mailbox behavior
- Media resource groups and their role in call control decisions
High-yield exam pattern: Expect scenario questions that describe a dial plan or partition setup and ask you to predict the outcome of a specific call. These are not memorization questions - they test whether you can trace logic through a configuration.
Key Takeaway
Do not just read about calling search spaces and partitions - build a small lab or work through several worked examples until you can predict call routing outcomes without hesitation.
Cloud and Hybrid Services Cheat Sheet
At 25%, Cloud and Hybrid Services is the domain most likely to feel unfamiliar to candidates who have spent their careers purely on-premises. This is also the area where the exam content evolves fastest, so treat this section as directional rather than exhaustive.
Domain 5: Cloud and Hybrid Services
Focus on how cloud-based calling and administration interact with (and sometimes replace) traditional on-prem components.
- Webex Calling architecture and how it differs from on-prem call control
- Control Hub administration: user provisioning, license assignment, and org-level settings
- SIP as the common signaling thread between on-prem and cloud components
- Cloud APIs used for provisioning and management tasks
- Hybrid deployment models where on-prem CUCM and cloud services coexist
Because this domain rewards hands-on exposure more than theory, spend time in a Control Hub trial environment if you can get access to one. Reading documentation alone rarely sticks for API-related questions.
Infrastructure, Gateways, Media & QoS
The remaining four domains total 45% of the exam combined, and each deserves focused attention even though no single one dominates.
Domain 1: Infrastructure and Design (15%)
Covers foundational architecture decisions that everything else in the exam builds on.
- Deployment models and design considerations for collaboration infrastructure
Domain 2: Protocols and Endpoints (10%)
Signaling and endpoint behavior questions, often tied back to SIP concepts also tested in Domain 5.
- Endpoint registration and protocol-level troubleshooting
Domain 4: Voice Gateways and Session Border Controllers (10%)
Focuses on how calls cross trust boundaries between internal networks and external providers.
- Gateway and SBC roles in call signaling and media handling
Domain 6: Media and QoS (10%)
Tests understanding of how voice and video media are prioritized and protected across a network.
- Quality of service markings and their impact on call quality

Registration and Retake Mechanics
Logistics questions cause unnecessary stress right before test day. Here's the compressed version.
- Where to test: Pearson VUE test centers or OnVUE online proctoring - pick based on your comfort with remote proctoring requirements.
- Cost: US$400 plus applicable tax; Cisco Learning Credits are accepted as payment.
- Passing score: Cisco does not publish a single fixed cut score for this scaled exam; see the CLCOR Passing Score 2026 page for how scoring actually works.
- If you fail: you must wait five calendar days, starting the day after your attempt, before you can retest.
- Validity: Certification and written-exam credit both last three years from the pass date.
- Renewal: Retake an eligible exam before expiration, or renew via Continuing Education - 40 credits for the Specialist certification, 80 credits for full CCNP Collaboration. CE renewal does not extend the window for combining separate exam passes toward a certification.
For every registration fee, retake cost, and renewal cost scenario spelled out in dollar terms, see the CLCOR Certification Cost 2026 breakdown. And if scheduling around blueprint changes or testing windows is a concern, check CLCOR Exam Dates 2026 before you lock in a date.
Final-Week Review Schedule
Generic study advice (spaced repetition, timed drills) only matters if it's mapped to this exam's actual weight distribution. In the final stretch, allocate review time proportionally rather than evenly across all six domains.
On-Premises Call Control
- Redo CUCM dial-plan scenario questions until routing logic is automatic
- Review Unity Connection integration points
Cloud and Hybrid Services
- Walk through Control Hub provisioning steps hands-on if possible
- Review SIP's role bridging on-prem and cloud
Remaining Four Domains
- Cycle through Infrastructure and Design, Protocols and Endpoints, Gateways/SBCs, and Media and QoS
- Focus only on gaps identified in earlier practice
Light Review Only
- Skim the domain weight table, not new material
- Confirm test center or OnVUE system check is complete
This kind of weighted, domain-first pacing is exactly what a proper CLCOR study guide should build around - not a one-size-fits-all calendar. Once you've internalized the weighting logic, run full-length timed sets on our CLCOR practice test platform to simulate the 120-minute pressure before test day.
Key Takeaway
Spend roughly proportional time to domain weight: On-Premises Call Control and Cloud and Hybrid Services combined should consume over half your final review hours.
FAQ
It's a closed-book, computer-based exam with multiple-choice and drag-and-drop items, plus the possibility of performance-based lab items, delivered over 120 minutes.
Start with On-Premises Call Control (30%) since it's the heaviest domain, then move to Cloud and Hybrid Services (25%). Together they cover more than half the exam content.
US$400 plus applicable tax, and Cisco Learning Credits are accepted as a payment method.
Five calendar days, starting the day after the failed attempt, before you're eligible to retest.
No. Passing meets the core exam requirement for CCNP Collaboration and qualifies you for the CCIE Collaboration lab exam, but full CCNP Collaboration status also requires passing a separate concentration exam.
