Implementing Cisco Collaboration Cloud and Edge Solutions (300-820 CLCEI) Exam Guide
The 300-820 CLCEI validated practical knowledge of Cisco collaboration cloud and edge solutions, including Expressway, Cisco Unified IM and Presence, and Webex Teams hybrid technologies. It served candidates pursuing the CCNP Collaboration or Cisco Certified Specialist - Collaboration Cloud & Edge Implementation credentials. The important decision now is not how to schedule CLCEI preparation: Cisco retired the exam on February 2, 2026, and lists 300-820 CLHCT as its replacement. Use this guide to understand the former blueprint, preserve relevant skills, and choose the current path.
Is 300-820 CLCEI still available?
No. Cisco retired 300-820 CLCEI on February 2, 2026, and the exam is no longer available for certification or recertification. Cisco lists 300-820 CLHCT as the replacement. Candidates should therefore stop looking for a CLCEI appointment and review the current CLHCT requirements and exam topics before committing to study materials.
What happens to a certification earned through CLCEI?
Cisco states that retired exams are no longer available for certifying or recertifying, while certifications earned from them remain valid until their individual expiration dates. If you already passed CLCEI, check your certification record for its individual expiration date rather than assuming that retirement immediately invalidates the credential.
Which date should a candidate use when reviewing old material?
Cisco’s retirement information identifies February 2, 2026, as the retirement date, while Cisco’s certification update described February 2, 2026, as the last day to test on the previous topics and February 3, 2026, as the first day for the updated topics. For present planning, treat CLCEI as closed and use Cisco’s current CLHCT information.
What did the former CLCEI exam validate?
The former exam focused on implementing and troubleshooting collaboration services at the boundary between on-premises infrastructure, remote users, and external organizations. Its coverage included Cisco Expressway configurations, Cisco Unified IM and Presence, Cisco Webex Teams hybrid and emerging technologies, and integration between Cisco Unified Communications Manager and Expressway Series systems.
Which professional tasks matched the exam?
The associated course objectives emphasized configuring and troubleshooting Cisco Unified Communications Manager and Cisco Expressway Series integration. They also covered Business-to-Business collaboration solutions and Mobile and Remote Access security and integration options. These objectives point to an implementation-oriented exam: candidates needed to connect components, validate behavior, and isolate configuration faults rather than study cloud terminology in isolation.
Who was the former exam for?
CLCEI was relevant to collaboration engineers, voice and video administrators, consultants, and support professionals working with Expressway-connected environments. It was also a concentration exam associated with CCNP Collaboration and the Cisco Certified Specialist - Collaboration Cloud & Edge Implementation certifications. Because the exam is retired, this audience should now map its objectives to the replacement exam before studying.
What were the former blueprint domains?
The former Cisco exam-topic guide allocated 25% to Key Concepts, 25% to Initial Expressway Configurations, and 25% to Mobile and Remote Access. The supplied topic evidence does not identify the remaining allocation, so candidates should not treat these three percentages as a complete 100% blueprint or redistribute the unlisted portion themselves.
What belongs in Key Concepts?
The Key Concepts domain included NAT complications, ICE, TURN, STUN, Expressway media traversal, protocol interworking, licensing, SIP media-encryption modes, dial-plan elements, and backup and restore procedures. Study these as connected troubleshooting subjects: a traversal failure, for example, can involve addressing, firewall behavior, media paths, and protocol expectations rather than one isolated setting.
What belongs in Initial Expressway Configurations?
The Initial Expressway Configurations domain included Expressway DNS, network interfaces, certificates, Quality of Service, clustering, firewall rules, dial-plan elements, toll-fraud prevention, and Business-to-Business collaboration solutions. A useful lab sequence is to establish name resolution and interfaces first, then certificates and policy controls, followed by routing and external-call validation.
What belongs in Mobile and Remote Access?
Mobile and Remote Access was one of the former blueprint domains and was also represented in the course objectives through security and integration options. Prepare by tracing the remote-user path end to end: identity and authentication, traversal components, policy decisions, media behavior, and the operational evidence needed to distinguish a client problem from an Expressway or Unified Communications Manager problem.
How should you study the former Expressway topics?
Build a dependency map before memorizing commands or menu locations. Start with DNS, interfaces, certificates, and firewall reachability; then add traversal, clustering, dial-plan rules, authentication, and media security. This order reflects how a broken foundation can make higher-level configuration appear faulty and gives each lab a clear verification point.
Begin with the network and trust foundation
Document every relevant hostname, interface, address relationship, certificate name, and firewall path in a lab worksheet. Then verify that the names used by the collaboration components resolve as intended and that certificates support the required trust relationships. Keep separate notes for configuration facts and observed symptoms; mixing them makes later troubleshooting less reliable.
Add traversal and media behavior
Next, study NAT complications together with ICE, TURN, STUN, and Expressway media traversal. Do not learn these as a list of acronyms. Draw the signaling path and media path separately, mark where address translation occurs, and record which component is expected to provide or relay connectivity. That model is more useful than memorizing one successful topology.
Finish with policy and resilience
After basic connectivity works, add dial-plan controls, toll-fraud prevention, SIP media-encryption modes, licensing considerations, clustering, and backup and restore procedures. Test how a restrictive rule changes call behavior, how a certificate or node changes affects trust, and how a recovery procedure restores service. Use controlled changes so each result has an identifiable cause.
How should you prepare for Business-to-Business collaboration?
Treat Business-to-Business collaboration as an interoperability and security problem, not simply an external dialing exercise. Identify the participating systems, name resolution requirements, trust relationships, protocol boundaries, media traversal path, and dial-plan decision. Then verify both successful calls and rejected calls so you understand which policy is enforcing the intended boundary.
What should a B2B study checklist contain?
Your checklist should cover Expressway DNS, certificates, firewall rules, traversal behavior, protocol interworking, dial-plan elements, and toll-fraud controls because each appears in the former topic evidence. Add a clear expected result for signaling, media, identity, and authorization. If the call fails, record the first failed stage instead of labeling the entire feature as unavailable.
Which mistakes weaken B2B preparation?
A common mistake is changing several variables at once: firewall rules, certificates, and dial-plan entries may all be edited before the candidate tests again. That prevents causal diagnosis. Another mistake is validating only an outgoing call. Test the intended direction, identity presentation, media, and rejection behavior, while keeping the exercise within an authorized lab or production change process.
How should you prepare for Mobile and Remote Access?
Study Mobile and Remote Access by following a remote endpoint from authentication through signaling and media. Include the security and integration options named in the former course objectives, then compare expected behavior for an internal endpoint and a remote endpoint. The goal is to explain where the path changes and which component owns each decision.
What should you verify in a remote-access lab?
Verify name resolution, certificate trust, authentication behavior, traversal connectivity, policy restrictions, and media establishment in that order. Record whether a failure occurs before authentication, after authentication but before signaling, during signaling, or during media negotiation. This staged record helps separate identity problems from traversal and media problems.
How should security be included in revision?
Include toll-fraud prevention, certificate handling, authentication options, SIP media-encryption modes, and firewall policy in the same study plan as feature configuration. A remote-access design is incomplete if it connects users but does not control who can reach which services. Review every permitted path and ask what prevents an unintended call or routing outcome.
What practical lab environment should you build?
Use a small, repeatable topology rather than a large environment that is difficult to reset. The former course included lessons and hands-on labs and was designed as five days of instructor-led classroom training or equivalent e-learning, which supports a practice model combining explanation with configuration. If you lack a lab, use diagrams, configuration reviews, and fault-injection exercises instead of claiming production experience.
What should the topology represent?
Represent the core collaboration system, Expressway components, a boundary or translated network, a remote user path, and an external Business-to-Business path. The exact products and versions in a current lab may differ from the retired exam context, so label the exercise as historical CLCEI preparation and confirm current product behavior in Cisco documentation before applying it operationally.
Which exercises produce the most useful evidence?
Create one baseline exercise, then deliberately introduce one fault at a time: a name-resolution error, certificate mismatch, blocked firewall path, incorrect dial-plan rule, unsuitable media-encryption mode, or authentication failure. For each fault, write the symptom, likely layer, verification method, correction, and regression test. This builds a troubleshooting record rather than a collection of untested notes.
What was the former exam format?
Cisco’s former exam overview listed a 90-minute duration and English as the available language for 300-820 CLCEI. Those details describe the retired exam only; they should not be used to infer the format, duration, or language of 300-820 CLHCT. Candidates moving to the replacement must confirm its current details through Cisco before registration.
How should former format information affect preparation?
Use the historical format as context, not as a scheduling target. Since CLCEI cannot now be booked, there is no value in planning around its former duration or language. For the replacement, verify the official exam page, current topic document, registration information, and any delivery requirements directly before selecting a date.
Was the former course a substitute for exam preparation?
The former course offered lessons and hands-on labs, but completing training alone would not demonstrate mastery of every exam objective. Use training content to establish concepts, then create independent troubleshooting scenarios and verify each topic against the official exam-topic guide. For a retired exam, use the course primarily to preserve transferable knowledge for the current replacement path.
How should a candidate sequence study time now?
Do not follow a CLCEI-only schedule unless the objective is historical knowledge or maintaining familiarity with an earned credential. First determine whether your target is 300-820 CLHCT, another current collaboration exam, or operational skill development. Then obtain the current blueprint and divide study between knowledge review, guided configuration, fault isolation, and final readiness checks.
A decision-first roadmap
In the first study session, confirm the target credential and read the current Cisco exam description. In the next session, compare its domains with your existing Expressway and hybrid-collaboration knowledge. Keep CLCEI notes in a separate archive so retired percentages and terminology do not silently become assumptions about the replacement exam.
A foundation phase
Review DNS, certificates, interfaces, NAT, firewall behavior, traversal concepts, authentication, dial-plan logic, and media security. Use the former CLCEI topics as a skills inventory, not as a current blueprint. Mark each subject as explain, configure, troubleshoot, or not yet practiced; this exposes gaps more accurately than rereading the same material.
An implementation phase
Perform a baseline deployment or configuration walkthrough, then repeat it from a blank worksheet. Add B2B and remote-access scenarios and document expected signaling and media behavior. Include backup and restore and clustering concepts where relevant to your target exam or work environment. Review the source documentation whenever the current platform differs from the former CLCEI scope.
A validation phase
Validate readiness by explaining a complete call path, diagnosing a deliberately introduced fault, and justifying each security control. Use original practice questions or your own scenario prompts, not leaked questions or exam dumps. No memorization resource can guarantee a passing result, and unauthorized material can train you on obsolete or misleading content.
Which preparation mistakes should you avoid?
The largest mistake is studying a retired blueprint as though it were the current CLHCT blueprint. Other errors include memorizing percentages without domain labels, skipping hands-on verification, treating certificates as an afterthought, and troubleshooting only signaling while ignoring media. Keep an explicit boundary between verified historical facts and current exam requirements.
Why is memorizing menu paths insufficient?
Menu familiarity does not show whether you understand dependencies between DNS, certificates, firewall policy, traversal, dial plans, authentication, and media. Configuration steps should always be paired with a reason, an expected result, and a fault-isolation method. That approach remains valuable even when product interfaces or exam objectives change.
Why should you avoid bare blueprint comparisons?
The former source identifies 25% for Key Concepts, 25% for Initial Expressway Configurations, and 25% for Mobile and Remote Access. Each percentage belongs to its named domain, and the supplied evidence does not provide a complete allocation. Presenting those figures as a full comparison would create a false impression of exam coverage.
Why are dumps a poor substitute for preparation?
Dumps and leaked-question claims are not a reliable study method and cannot guarantee a pass. They may contain obsolete CLCEI content, omit the reasoning behind an answer, or encourage memorization without configuration skill. Build knowledge from Cisco’s official topics and course material, then use authorized practice activities to test your reasoning.
What should you do next?
If you planned to take CLCEI, stop the registration process and move to Cisco’s current 300-820 CLHCT information. If you already earned CLCEI, verify the individual certification expiration date and plan recertification through a currently available route. Preserve the former Expressway notes as a technical reference, but do not treat them as the replacement exam blueprint.
A short action checklist
Confirm your certification or exam goal; open Cisco’s current CLHCT page and exam topics; archive the former CLCEI blueprint; inventory your Expressway, B2B, remote-access, media, and security skills; build one repeatable lab or scenario set; and schedule only after checking the current official registration details.
Which official pages should be checked?
Use Cisco’s retired-exam page for status, the former CLCEI overview and topic guide for historical scope, the former course page and course PDF for training objectives, and Cisco’s collaboration certification update for the transition context. Recheck these pages before making a time-sensitive certification decision because exam information can change.
Conclusion
300-820 CLCEI is a retired exam, so the practical preparation decision is to redirect any planned attempt toward Cisco’s listed replacement, 300-820 CLHCT. Its former scope remains useful for understanding Expressway, remote access, B2B collaboration, traversal, certificates, media, and security. Keep historical facts labeled, verify the current blueprint before studying, and use labs and troubleshooting records to turn topic names into transferable implementation skill.
