Cisco CLCEI 300-820 exam-day guide
Cisco CLCEI 300-820 · Prepare for the day ahead.
Your checklist
Government-issued photo ID
Bring the exact ID name that matches your registration. For online proctoring, confirm with the provider which ID types are accepted and whether a secondary ID is required; for test-center delivery, check the center's specific requirements in your appointment confirmation.
Appointment confirmation and exam code
Save the confirmation email and any exam/eligibility code offline on your phone and in a printed copy. You may need the exam ID or a registration code at check-in. Confirm with the provider how the exam is delivered (test center vs. online proctored) and what identifiers you must present.
Know the exam blueprint and time budget
Review the official 300-820 exam topics page the week before. The exam is 90 minutes with roughly 55-65 questions; treat that as ~80-90 seconds per question and reserve the last 10 minutes for flagged items. Confirm the current duration and question count with the provider, as Cisco occasionally updates them.
Working webcam, microphone, and stable internet (online proctoring)
If testing online, run the provider's system test 24-48 hours ahead. Use a wired or stable connection, close all other applications, and have a phone available as a backup contact method for the proctor. Confirm with the provider whether a room scan and desk clearance are required.
Quiet, private room with a cleared desk
For online delivery, remove papers, phones (unless instructed otherwise), second monitors, and anything with writing from the desk and walls behind you. Confirm with the provider what is permitted in the room; policies on whiteboards, notes, and drinks vary.
Scratch materials policy confirmed
Some deliveries provide an on-screen whiteboard or permit a dry-erase sheet; others prohibit all scratch paper. Do not assume. Confirm with the provider before test day so you can practice subnetting and call-flow diagrams under the actual constraint.
Calculator policy confirmed
Confirm with the provider whether an on-screen calculator is built into the exam and whether a physical calculator is allowed. If not allowed, practice estimating bandwidth and codec bitrate math mentally.
Break policy confirmed
Confirm with the provider whether scheduled or unscheduled breaks are permitted and whether the clock stops. Plan hydration and caffeine around the answer you get.
Review notes on the four domains
Focus last-minute review on: (1) call control and dial plan (CUCM, Expressway registrations, URI dialing), (2) B2B and mobility (Expressway-C/E, MRA, Jabber, Mobile and Remote Access), (3) collaboration edge and security (certificates, TLS, firewall traversal, SIP/H.323), (4) meetings and messaging (Webex Meetings, Webex App, hybrid calendar). Keep it to one or two pages you can skim in 15 minutes.
Practice with the exam's question style
Expect multiple-choice, multiple-answer, drag-and-drop, and possibly simulation-style items. Practice reading the full stem and identifying the single best answer when several seem plausible. Do not rely on memorized question dumps; they are inaccurate and violate the exam agreement.
Plan the logistics
For a test center, confirm the address, parking, and arrival time (often 15-30 minutes early). For online proctoring, log in early to complete identity checks. Confirm with the provider the exact check-in window and late-arrival policy.
Backup plan for technical failure
Know the provider's support phone number and have it saved. If the connection drops or the proctor session fails, note the time and contact support immediately; do not restart the exam on your own. Confirm with the provider the procedure for technical interruptions and whether the attempt can be rescheduled.
Plan the day
Re-read the official exam topics and map each bullet to a study note. Identify your two weakest areas and spend the remaining time there rather than re-reading everything. Verify your appointment details, delivery method, and ID requirements. Confirm with the provider the break, scratch-paper, and calculator policies. Run the online system test if applicable.
Do one timed practice set under exam conditions (no pauses, no notes). Review every wrong answer and write a one-line reason for the correct choice. Stop adding new material after this point; consolidate instead. Verify your internet connection and webcam/microphone if testing online.
Light review only: certificates and PKI basics, Expressway registration and traversal logic, SIP vs. H.323 differences, URI dialing, and Webex meeting/hybrid calendar concepts. Prepare your ID, confirmation, and any permitted materials. Confirm the start time in your local time zone and set two alarms. Get a full night's sleep; avoid cramming new topics.
Eat a normal meal and limit caffeine. Do a final 10-15 minute skim of your one-page notes. For a test center, arrive 15-30 minutes early with your ID. For online proctoring, close all applications, clear your desk, and start the check-in early. Keep your phone nearby only if the provider instructs you to.
Read the full question before looking at options; note qualifiers like 'best', 'first', 'not', and 'most likely'. Answer confident questions quickly, flag uncertain ones, and move on. Do not leave anything blank if there is no penalty for guessing (confirm with the provider). For drag-and-drop, place all items even if unsure. Use the last 10 minutes to revisit flagged items and confirm you answered every question.
Note which topics felt weak while memory is fresh, in case you need to retake. If you did not pass, review the score report domain breakdown and schedule the retake after the provider's waiting period, if any. Confirm with the provider the retake policy and any waiting time.
Rules to check
Present the exact government-issued photo ID used at registration; name mismatches can block entry. Confirm with the provider which ID types are accepted and whether a secondary ID is needed.
Do not bring notes, phones, smart watches, or other devices into the testing area unless the provider explicitly permits them. For online delivery, follow the proctor's instructions on room scans and desk clearance.
Do not communicate with anyone other than the proctor during the exam, and do not read questions aloud if the proctor instructs silence. Confirm with the provider what communication is allowed.
Breaks are governed by provider policy; confirm in advance whether they are allowed, whether the clock runs, and whether you must remain on camera. Do not leave the camera view without proctor permission.
Scoring is criterion-referenced against the exam blueprint; there is no partial credit for multi-part items, and results are typically reported as pass/fail with a domain-level breakdown. Confirm with the provider the current passing score and score-report format.
Do not attempt to capture, share, or reconstruct exam content. This violates the exam agreement and can void your result and affect eligibility for future exams.
If a technical failure occurs, stop and contact provider support immediately; do not attempt to restart or continue on your own. Confirm with the provider the interruption and rescheduling procedure.
Follow all proctor instructions. Suspected misconduct can lead to score cancellation; if you are unsure whether an action is allowed, ask the proctor before doing it.
