The Cisco 300-820 CLHCT exam is aimed at engineers who need to configure, operate, secure, and troubleshoot modern Cisco collaboration environments. Its full name is Implementing Cisco Collaboration Hybrid and Cloud Technologies, and the current v2.0 blueprint places a strong emphasis on Webex, cloud calling, identity management, hybrid migration, security, and programmability.
Although 300-820 is a professional-level Cisco exam, it is not relevant only to senior voice engineers. It can also provide a structured learning path for students, junior network engineers, unified communications support staff, and anyone moving from traditional IP telephony into cloud-based collaboration.
The important point is that this is no longer an exam centered only on on-premises call-control infrastructure. The current blueprint reflects how collaboration systems are actually being deployed: users and devices are managed from the cloud, identity comes from enterprise directories, PSTN connectivity may remain local, and administrators are increasingly expected to understand security and APIs as well as dial plans.
What Is the Cisco 300-820 CLHCT Exam?
300-820 CLHCT is one of the concentration exams in the CCNP Collaboration certification track. It focuses on Cisco collaboration services that operate in cloud and hybrid environments, particularly the Webex Suite, Webex Calling, Control Hub, cloud-connected endpoints, identity services, security, migration, and APIs.
Passing the exam currently earns the Cisco Certified Specialist – Collaboration Cloud & Edge Implementation certification. It also satisfies the concentration exam requirement for CCNP Collaboration.
However, passing 300-820 by itself does not award the complete CCNP Collaboration certification. To earn CCNP Collaboration, a candidate must pass:
- The 350-801 CLCOR core exam; and
- One eligible concentration exam, such as 300-820 CLHCT.
This makes CLHCT useful in two ways. It is a standalone specialist credential, and it can also be one half of a broader professional-level certification path.

CLHCT v2.0 Versus the Older CLCEI Exam
Important: Do not prepare for the current exam using only old 300-820 CLCEI materials.
The exam code remains 300-820, but the exam was significantly revised. The older exam was known as CLCEI, or Implementing Cisco Collaboration Cloud and Edge Solutions. Cisco retired that version on February 2, 2026, and introduced CLHCT v2.0 on February 3, 2026.
Some older training remains useful for foundational topics, but the new blueprint places clearer emphasis on areas such as:
- Webex Calling administration and troubleshooting
- Control Hub calling features
- Cloud identity and user management
- Site survivability and local gateways
- Migration from on-premises systems to the cloud
- Webex security architecture
- Cloud collaboration APIs
- AI features within collaboration solutions
When evaluating a book, video course, practice test, or lab guide, check that it explicitly covers CLHCT v2.0. A resource labeled only “300-820” may still follow the retired CLCEI blueprint.
Cisco 300-820 CLHCT Exam Topics
The current 300-820 exam blueprint is divided into seven domains. The two largest domains—Suite and Devices Configuration and Suite and Devices Management—represent half of the exam weighting.
| Domain | Weight | Main Focus |
|---|---|---|
| 1.0 Suite and Devices Configuration | 25% | SSO, directory synchronization, hybrid calendar, local gateways, survivability, and calling features |
| 2.0 Cloud Management | 10% | User-management troubleshooting, SCIM, RBAC, bandwidth, and QoS |
| 3.0 Suite and Devices Management | 25% | Webex Calling, call routing, meetings, messaging, and endpoint registration |
| 4.0 Suite and Device Administration | 10% | User, organization, and site administration, AI features, and migration tools |
| 5.0 Hybrid and Migration to the Cloud | 10% | Cloud Connected UC, Control Hub migration, and advanced dial plans |
| 6.0 Security | 10% | Webex security, compliance services, security architecture, and Hybrid Data Security |
| 7.0 APIs and Programmability | 10% | Developer portals, device macros, and Webex APIs |
1. Suite and Devices Configuration — 25%
This domain tests the configuration work required to bring users, services, gateways, and devices into a cloud collaboration environment.
Candidates should understand:
- Single sign-on configuration
- Directory synchronization
- Hybrid calendar integration with cloud mail services
- Certificate-based and registration-based local gateways
- Site survivability
- Control Hub calling features such as hot desking and auto attendants
For a beginner, the difficult part is often not memorizing where a setting appears in Control Hub. The real challenge is understanding the dependencies behind the configuration. SSO depends on identity federation. Directory synchronization depends on attribute mapping and a defined source of truth. A local gateway depends on routing, certificates or registration, firewall policy, DNS, and a correctly designed dial plan.
2. Cloud Management — 10%
The Cloud Management section connects traditional network operations with cloud administration. Candidates must be able to troubleshoot user-management technologies such as:
- Control Hub Directory Connector
- System for Cross-domain Identity Management, or SCIM
- Role-based access control, or RBAC
The domain also includes bandwidth and Quality of Service troubleshooting for Webex services and collaboration endpoints. A collaboration engineer should be able to determine whether a poor meeting or call is caused by the application, the endpoint, the WAN, packet loss, excessive latency, jitter, wireless instability, or an incorrectly implemented QoS policy.
3. Suite and Devices Management — 25%
This is one of the most operationally important parts of the exam. It covers troubleshooting across Webex Calling, cloud meetings, messaging, and endpoint registration.
Webex Calling routing topics include:
- Operating modes
- Locations
- Telephone numbers
- Translation patterns
- Trunks and route groups
- Dial plans
- Call permissions
These topics should be studied as a complete call-routing system rather than as isolated menu options. For example, when a call fails, an engineer may need to trace the number assignment, location policy, route group, trunk, local gateway, normalization rules, and PSTN path.
You should also know how to approach failures involving:
- Cloud meetings
- Cloud messaging
- Device activation
- Endpoint registration
- User entitlement or licensing
- Network connectivity to Webex services
4. Suite and Device Administration — 10%
This domain focuses on routine administration at user, organization, and site levels.
Examples include:
- Adding, modifying, and removing users
- Claiming or configuring organizational domains
- Managing organization-wide settings
- Enabling integrations and security options
- Adding and managing multiple sites
- Applying common site settings
- Understanding available cloud collaboration AI features
- Describing Control Hub migration tools
The AI objective does not mean that candidates need to become machine-learning engineers. The more practical goal is to understand where AI-assisted collaboration features fit into meetings, calling, messaging, administration, and the user experience.
5. Hybrid and Migration to the Cloud — 10%
Most enterprises do not move every user, device, trunk, and application to the cloud in a single step. As a result, hybrid architecture and migration planning are central collaboration skills.
The blueprint specifically includes:
- Cloud Connected UC
- Control Hub migration workflows
- Hybrid connectivity between on-premises and cloud services
- Advanced dial-plan configuration
Candidates should understand the difference between simply connecting an on-premises system to cloud management and actually migrating calling workloads to Webex. Inventory, user identity, extension ranges, PSTN design, emergency calling, devices, security policies, and rollback planning all influence a successful migration.
6. Security — 10%
Collaboration traffic contains conversations, meeting content, files, recordings, telephone numbers, identities, and potentially regulated business data. Security is therefore not an optional add-on.
The CLHCT blueprint expects candidates to understand security for:
- Administration
- Endpoints
- Meetings
- Compliance
It also includes the Webex cloud security realm architecture, including:
- Identity service
- Key management service
- Indexing service
- Compliance service
- Content server
Candidates should also understand the purpose and deployment model of Hybrid Data Security. At a conceptual level, the engineer must know which components remain cloud-hosted, which security functions can be controlled by the organization, and how identity, encryption, key management, indexing, and compliance interact.
7. APIs and Programmability — 10%
Modern collaboration administrators are increasingly expected to automate repetitive tasks and integrate Webex with other business systems.
The blueprint includes:
- Webex App Hub
- Webex Developer Portal
- RoomOS Portal
- Macros on collaboration devices
- Messaging APIs
- Meeting APIs
- Calling APIs
- People APIs
- Events APIs
You do not need to be a full-time software developer, but you should be comfortable with basic REST API concepts. That includes HTTP methods, authentication, access tokens, JSON payloads, response codes, pagination, and simple error handling.
A useful practical exercise is to retrieve user or device information through an API, parse the JSON response, and then use the returned data in a small script or reporting workflow.
Core Technologies Behind the CLHCT Exam
Cisco Webex Control Hub
Control Hub is the central administration interface for many of the technologies covered by the exam. It is used to manage organizations, users, services, devices, sites, calling features, security settings, analytics, and integrations.
Students should avoid learning Control Hub as a collection of screenshots. Cloud interfaces change. It is more valuable to understand the object model behind the interface: organizations contain users, locations, devices, services, policies, numbers, workspaces, and integrations.
Identity, SSO, SCIM, and Directory Synchronization
Cloud collaboration depends heavily on identity. You should be able to distinguish among:
- Authentication: proving who a user is
- Authorization: determining what that user may access
- SSO: using an enterprise identity provider for authentication
- Directory synchronization: copying selected identity data into Webex
- SCIM: standards-based user provisioning and deprovisioning
- RBAC: assigning administrative permissions according to role
Troubleshooting identity requires attention to domains, claims, attributes, certificates, synchronization scope, account status, licensing, and the relationship between the identity provider and Control Hub.
Webex Calling and PSTN Connectivity
Webex Calling provides enterprise calling services from the cloud, but many deployments still require connectivity to a local carrier, an existing PBX, or an on-premises voice gateway.
Important concepts include:
- Locations and number assignment
- Calling permissions
- Trunks and route groups
- Local gateways
- Dial plans and number normalization
- Inbound and outbound call routing
- Site survivability
- PSTN integration
Network engineers already familiar with routing protocols may find voice routing conceptually familiar. Both disciplines involve matching an input against a set of rules and selecting a path. The difference is that telephone-number formats, translations, permissions, carrier requirements, and emergency-calling rules introduce additional constraints.
QoS and Media Troubleshooting
Signaling can establish a call successfully while the media still performs badly. A complete troubleshooting method should distinguish between the signaling path and the audio or video media path.
Review these networking fundamentals:
- Packet loss
- Latency
- Jitter
- Bandwidth utilization
- Queueing and congestion
- Traffic classification and marking
- Wireless signal quality
- Firewall and proxy behavior
- DNS and NTP availability
- TLS and certificate validation
When troubleshooting a poor-quality call, begin with evidence. Identify whether the problem affects one user, one site, one access method, one ISP, or the entire organization. Then correlate endpoint information, Control Hub analytics, network telemetry, and routing behavior.
Hybrid Architecture and Migration
A hybrid design allows an organization to combine existing Unified Communications infrastructure with cloud services. This may be a temporary migration stage or a long-term architecture.
Strong candidates understand the reasons an organization might retain on-premises components, including local PSTN access, legacy integrations, regulatory requirements, phased migration, survivability, and existing device investments.
Security and Compliance
Security questions are easier when you understand the data lifecycle. Ask:
- How is the user authenticated?
- How is the device trusted?
- Where is content stored?
- Who controls encryption keys?
- How is content indexed?
- What information is available to compliance personnel?
- How are administrators authorized and audited?
This approach is more effective than memorizing isolated product terms.
APIs, JSON, and Device Macros
At minimum, a CLHCT candidate should be able to read a basic API request and response. You should recognize:
- GET, POST, PUT, and DELETE operations
- HTTP status codes
- Bearer-token authentication
- JSON objects and arrays
- Required and optional parameters
- API rate limits and pagination concepts
- Basic event-driven integrations
For device automation, review how RoomOS macros can respond to events, interact with user-interface elements, and control supported device functions.
How Valuable Is the Cisco 300-820 Certification?
The value of the Cisco 300-820 certification depends heavily on the role you want and the environment in which you work.
Where It Has Strong Value
CLHCT is particularly relevant for organizations and service providers using:
- Cisco Webex
- Webex Calling
- Cisco collaboration endpoints
- Cisco Unified Communications Manager
- Hybrid cloud collaboration
- Local gateways and enterprise PSTN connectivity
It can support career paths such as:
- Collaboration administrator
- Junior unified communications engineer
- Webex support engineer
- Cloud voice engineer
- Collaboration solutions engineer
- Unified communications consultant
- Network engineer with collaboration responsibilities
What the Certification Demonstrates
A pass indicates that the candidate has studied a defined set of professional-level cloud collaboration topics. It also provides employers with a recognizable Cisco credential that is easier to evaluate than an unstructured list of technologies.
The exam is most valuable when combined with practical evidence, such as:
- A documented Webex lab
- A sample migration design
- A call-routing diagram
- An identity-integration troubleshooting checklist
- A small API automation project
- Experience supporting real users and endpoints
What the Certification Does Not Guarantee
No certification guarantees that a candidate can design or troubleshoot every production environment. CLHCT also does not replace fundamental networking, security, voice, and systems knowledge.
Employers are likely to value the credential more when the candidate can explain why a design works, describe how to isolate a fault, and demonstrate hands-on familiarity with the platform.
Who Should Take the 300-820 CLHCT Exam?
The exam is a logical choice for:
- Network engineers moving into collaboration or unified communications
- Voice engineers transitioning from on-premises systems to Webex
- Administrators responsible for Control Hub
- Engineers supporting Webex Calling deployments
- Students pursuing a cloud collaboration career
- CCNP Collaboration candidates who prefer a hybrid and cloud specialization
- Consultants working on collaboration migrations
It may be less suitable for someone who wants to focus exclusively on advanced on-premises call control. That candidate should also compare the CLHCT blueprint with Cisco’s other CCNP Collaboration concentration options.
Recommended Prerequisite Knowledge
Cisco does not list a formal prerequisite for the CCNP Collaboration certification. However, this is still a professional-level exam. Cisco notes that many CCNP candidates have several years of experience implementing collaboration solutions.
A beginner does not need to wait several years before studying, but should first develop a foundation in the following areas:
- IPv4 addressing and subnetting
- Routing and switching fundamentals
- DNS, DHCP, and NTP
- VLANs and access-layer design
- Basic QoS concepts
- SIP signaling
- RTP and media flows
- TLS and digital certificates
- Firewalls, NAT, and proxy behavior
- JSON and REST API fundamentals
- Basic identity and directory concepts
CCNA-level networking knowledge is a reasonable starting point, even though holding a CCNA certification is not mandatory.
An Eight-Week Cisco 300-820 Study Plan
The following schedule is suitable for someone who already understands basic networking and can study approximately seven to ten hours per week. Complete beginners may need to extend it to ten or twelve weeks.
| Week | Primary Topics | Practical Goal |
|---|---|---|
| 1 | Collaboration architecture, SIP, media, DNS, NTP, TLS, and QoS | Draw signaling and media paths for a basic cloud call |
| 2 | Control Hub, organizations, users, locations, sites, and devices | Navigate the administrative object model and document dependencies |
| 3 | SSO, directory synchronization, SCIM, RBAC, and user troubleshooting | Create an identity flow diagram and troubleshooting checklist |
| 4 | Webex Calling, numbers, permissions, translation patterns, trunks, and route groups | Build and trace several inbound and outbound call-routing scenarios |
| 5 | Local gateways, PSTN integration, survivability, endpoints, meetings, and messaging | Practice fault isolation across cloud, gateway, network, and endpoint layers |
| 6 | Cloud Connected UC, migration tools, hybrid architecture, and advanced dial plans | Write a phased migration plan for a fictional organization |
| 7 | Security architecture, compliance, key management, and Hybrid Data Security | Map identity, content, encryption, indexing, and compliance components |
| 8 | APIs, device macros, full blueprint review, and practice questions | Complete one API exercise and close all blueprint gaps |
Use the Blueprint as a Checklist
Create a spreadsheet or notes document containing every item in the official blueprint. Mark each objective with one of three statuses:
- Green: I can explain and troubleshoot it without notes.
- Yellow: I recognize it but need more practice.
- Red: I cannot explain or configure it.
This provides a more accurate measure of readiness than simply counting completed videos.
Building a Useful CLHCT Lab
Hands-on access to a complete enterprise Webex environment can be difficult for students. Even so, it is possible to build useful practical skills without reproducing an entire production deployment.
Recommended Lab Activities
- Explore an authorized Webex test organization or official Cisco training lab.
- Practice creating users, locations, workspaces, and devices.
- Document number assignment and call-routing logic.
- Compare registration-based and certificate-based gateway designs.
- Analyze sample call failures and determine the likely fault domain.
- Build diagrams showing identity, signaling, media, and management flows.
- Use the Webex developer documentation to test basic API requests.
- Parse a JSON response using Python or another scripting language.
- Create a simple RoomOS macro in a supported lab environment.
- Write a migration plan from an on-premises deployment to Webex Calling.
A Lab Does Not Need to Be Large
A small, well-documented lab is more valuable than a complex environment that you do not understand. For every exercise, record:
- The intended outcome
- The configuration steps
- The expected signaling or data flow
- The verification method
- One or two failure scenarios
- The troubleshooting process
This turns configuration practice into engineering practice.
Practical Exam Preparation Tips
1. Prioritize the Two 25% Domains
Suite and Devices Configuration and Suite and Devices Management account for 50% of the published blueprint. They should receive a proportionally large share of your preparation time.
2. Learn Workflows, Not Screenshots
Cloud interfaces evolve. Understand the sequence and dependencies behind a task instead of memorizing where a button appeared in a particular software release.
3. Practice Troubleshooting in Layers
Use a structured order:
- User and entitlement
- Configuration and policy
- Identity and authentication
- Endpoint status
- DNS, NTP, certificates, and connectivity
- Call routing and gateway behavior
- Media quality and QoS
- Cloud service status and analytics
4. Do Not Ignore APIs
APIs and programmability represent 10% of the blueprint. That is large enough to affect the result, and API knowledge is increasingly useful in real administration roles.
5. Understand the Verbs in the Blueprint
Cisco uses verbs such as describe, configure, implement, construct, diagnose, and troubleshoot. These imply different depths of knowledge.
- Describe: explain the purpose, components, and relationships.
- Configure: know required settings, dependencies, and verification.
- Implement: apply the technology in a deployment scenario.
- Construct: build or interpret an API request.
- Diagnose: analyze symptoms and evidence.
- Troubleshoot: isolate the cause and determine a corrective action.
6. Avoid Relying on Exam Dumps
Question dumps do not provide a reliable learning path, especially after a major blueprint update. Even when a question looks familiar, memorization will not help much if the scenario changes or requires troubleshooting across several technologies.
Use legitimate practice questions to identify weak areas, then return to documentation, labs, and the exam blueprint.
7. Verify the Exam Version Before Booking
Make sure all 300-820 preparation resources explicitly align with 300-820 CLHCT v2.0. The old CLCEI designation is a warning that the material may not fully cover the current objectives.
Is Cisco 300-820 Difficult?
For a student with no voice, Webex, or identity background, the exam is likely to feel difficult because it combines several disciplines:
- IP networking
- Unified communications
- Cloud administration
- Identity management
- Security
- Troubleshooting
- Automation
For an experienced Cisco collaboration engineer, the challenge may be different. Someone with strong on-premises Unified Communications Manager skills may need to spend more time on Control Hub, Webex Calling, cloud security, migration, and APIs.
The exam becomes manageable when the blueprint is divided into systems and workflows rather than treated as a long list of product features.
Final Assessment
The Cisco 300-820 CLHCT certification is a focused credential for engineers working at the intersection of networking, voice, cloud services, identity, and automation. Its value is strongest for candidates targeting Cisco Webex, Webex Calling, hybrid collaboration, or CCNP Collaboration roles.
For students and junior engineers, the exam provides a useful roadmap into a specialized field. It introduces not only collaboration products but also transferable skills such as identity integration, QoS troubleshooting, cloud migration, security architecture, REST APIs, and structured fault isolation.
The certification should not be viewed as a shortcut to a senior engineering role. A better goal is to use the blueprint to build a coherent technical foundation, create hands-on evidence of your skills, and demonstrate that you can explain how a collaboration service behaves when everything works—and how to diagnose it when it does not.
