I Failed Cisco CCNA (CCNA): What Should I Do Next?
I Failed Cisco CCNA (CCNA): What Should I Do Next?
Getting that failing score on your CCNA attempt hits hard. I’ve coached hundreds of network engineers through this exact moment, and I know what’s running through your head right now: panic, frustration, maybe even thoughts about giving up on networking entirely.
Stop. Take a breath. This is not the end of your networking career.
Direct answer
If you failed CCNA, here’s what happens: You can retake the exam after waiting 15 days from your test date. You’ll pay the full exam fee again ($300). Your failing score doesn’t go on any permanent record that employers see. Most importantly, failing CCNA once (or even twice) is incredibly common among successful network engineers.
The real question isn’t what happens if you fail – it’s what you do next that determines whether this becomes a learning experience or a roadblock.
What failing CCNA actually means (not what you think)
Let’s clear up some misconceptions immediately.
CCNA failure doesn’t mean you’re not cut out for networking. The exam covers six distinct domains testing everything from subnetting math to automation concepts. Failing usually means you’re weak in 1-2 specific areas, not that you lack networking aptitude.
It doesn’t appear on background checks or employer searches. Cisco doesn’t maintain a public database of failed attempts. Your next employer will never know you failed unless you tell them.
One failure is statistically normal. Based on my experience coaching CCNA candidates, roughly 40% fail on their first attempt. The pass rate improves dramatically on the second try when people address their actual weak spots instead of just studying harder.
Your score report is more valuable than a passing grade. I know that sounds backwards right now, but your failing score report shows exactly which domains need work. Candidates who pass barely often don’t know their weak areas and struggle in real networking roles.
The first 48 hours: what to do right now
You’re probably tempted to immediately reschedule and dive back into studying. Don’t. Here’s your actual 48-hour plan:
Day 1: Process and document
- Let yourself feel disappointed for exactly one day. This is normal.
- Don’t make any study decisions while you’re emotional.
- Save your score report somewhere safe. You’ll reference it constantly.
- Don’t post about failing on social media or networking forums yet.
Day 2: Initial analysis
- Print your score report and highlight every domain where you scored below 70%.
- Write down what you remember about questions that stumped you.
- Note which topics felt completely foreign versus topics where you made calculation errors.
- Research the 15-day waiting period policy on Cisco’s official certification page.
What not to do in these 48 hours:
- Don’t immediately buy new study materials
- Don’t schedule your retake yet
- Don’t ask for study advice on forums (you don’t know your problem areas yet)
- Don’t drastically change your study method
How to read your CCNA score report
Your CCNA score report shows performance in six domains, but most people misinterpret what these numbers mean.
Network Fundamentals (20% of exam): This covers OSI model, TCP/IP basics, Ethernet fundamentals. If you scored poorly here, you lack foundational knowledge that affects everything else. This is actually good news – fundamentals are the easiest domain to improve quickly.
Network Access (20%): VLANs, spanning tree, EtherChannel, wireless basics. Poor performance here usually means you can’t visualize how switches actually forward frames or you’re confused about VLAN tagging.
IP Connectivity (25%): Routing protocols, static routes, OSPF, EIGRP. This is the heaviest weighted domain. If you failed here, you probably struggle with routing table logic or can’t trace packet flow through routers.
IP Services (10%): DHCP, DNS, NAT, SNMP, QoS basics. Low scores here typically mean you memorized configurations without understanding the underlying services.
Security Fundamentals (15%): ACLs, wireless security, device hardening. Failing this domain usually means you can’t write effective ACL rules or don’t understand security concepts.
Automation and Programmability (10%): REST APIs, JSON, network automation tools. This is where many experienced network engineers struggle because they avoid programming concepts.
Critical insight: If you failed in Network Fundamentals or IP Connectivity, focus there first. These domains support everything else. If you passed those but failed in smaller domains like Automation, you might just need targeted study in those specific areas.
Why most people fail CCNA (and which reason applies to you)
After coaching CCNA candidates for years, I’ve identified five primary failure patterns. Figure out which describes your situation:
Pattern 1: Foundation gaps (Network Fundamentals score under 60%) You jumped into CCNA without solid networking basics. You might know how to configure VLANs but can’t explain why VLANs exist. You memorized OSPF commands but don’t understand why routers need routing protocols.
Signs this is you: You struggled with “why” questions, not “how” questions. You could recall configurations but couldn’t troubleshoot scenarios.
Pattern 2: Lab vs. theory disconnect (Network Access or IP Connectivity under 60%) You can follow lab guides perfectly but can’t adapt when the exam presents unfamiliar scenarios. You know the commands but don’t understand the underlying logic.
Signs this is you: Simulation questions felt impossible even though you’ve configured everything before. You got tripped up by troubleshooting scenarios.
Pattern 3: Math and calculation errors (IP Connectivity under 65%) You understand routing concepts but made critical errors in subnetting, VLSM, or route summarization. These are precision skills that require practice, not just understanding.
Signs this is you: You knew the concepts but ran out of time on calculation-heavy questions. You second-guessed yourself on subnet masks or wildcard masks.
Pattern 4: Modern networking knowledge gaps (Security or Automation under 50%) You’re strong on traditional networking but weak on current technologies. You might be an experienced engineer who learned networking before automation and cloud became central.
Signs this is you: Traditional routing and switching felt comfortable, but REST API and JSON questions were completely foreign.
Pattern 5: Study method mismatch (Failed across multiple domains) You used study materials that didn’t match how CCNA actually tests knowledge. You might have relied too heavily on brain dumps, outdated books, or materials that focused on memorization over understanding.
Signs this is you: Nothing on the exam looked familiar despite months of study. Questions seemed to test concepts you never encountered in your materials.
Your CCNA retake plan: a step-by-step approach
Week 1-2 (Before you can reschedule): Deep analysis
Start with your score report. For each domain where you scored under 70%, write specific gaps:
- Network Fundamentals gaps: “Don’t understand collision vs. broadcast domains” not “bad at fundamentals”
- IP Connectivity gaps: “Can’t trace OSPF LSA flooding” not “bad at OSPF”
- Security gaps: “Don’t know ACL processing order” not “bad at security”
Research the specific exam objectives within your weak domains. The CCNA blueprint lists exact subtopics. Don’t study entire domains – study specific knowledge gaps.
Week 3-4: Targeted remediation
Focus exclusively on your lowest-scoring domain first. If Network Fundamentals was your weakness:
- Start with packet flow through the OSI model
- Practice explaining why each layer exists
- Draw diagrams showing encapsulation/decapsulation
- Move to Ethernet frame format and collision domain concepts
- Practice until you can teach these concepts to someone else
If IP Connectivity was your weakness:
- Focus on routing table lookup logic
- Practice tracing packets through multiple router hops
- Understand administrative distance and metric differences
- Work through OSPF neighbor formation step-by-step
- Practice route summarization calculations daily
Week 5-6: Integration and simulation practice
Now combine your improved weak areas with areas where you scored well. Focus heavily on simulation-style questions that require applying multiple concepts together.
Practice troubleshooting scenarios that span multiple domains. CCNA loves questions where you need to understand spanning tree (Network Access) and routing (IP Connectivity) to solve a connectivity problem.
Week 7: Final assessment and scheduling
Take a comprehensive practice exam that mirrors actual CCNA difficulty. If you’re not scoring consistently above 85% on quality practice exams, wait another week.
Schedule your retake for week 8, giving yourself a buffer in case you need more time.
Critical retake timeline note: Check Cisco’s official certification page for exact waiting periods and scheduling policies. These can change, and you need current information.
What not to do after failing CCNA
Don’t immediately switch study materials. Your study materials probably weren’t the problem unless you failed across all domains. Switching materials often means starting over when you should be targeting specific gaps.
Don’t overstudy areas where you scored well. If you scored 80% in Network Fundamentals, don’t spend weeks reviewing OSI model basics. Focus your limited time on actual weaknesses.
Don’t avoid your hardest domain. Many candidates postpone studying their lowest-scoring area because it feels overwhelming. This guarantees you’ll fail again in the same place.
Don’t rely on brain dumps for your retake. Brain dumps give you false confidence and teach you to recognize specific question formats rather than understand concepts. CCNA question pools are large enough that memorizing answers is unreliable.
Don’t rush the retake. The 15-day waiting period exists for a reason. Use every day of it. Retaking too quickly usually leads to repeating the same mistakes.
Don’t study in isolation. Find someone who can verify your understanding. Explaining networking concepts out loud reveals gaps that reading silently misses.
How Certsqill helps you identify exactly what went wrong
Here’s where most CCNA retake attempts fail: people guess at their weak areas instead of identifying them precisely.
Your score report tells you which domains were problematic, but it doesn’t tell you which specific concepts within those domains caused the issues. Was your Network Access failure due to spanning tree confusion or VLAN trunking gaps? Was your IP Connectivity weakness about OSPF neighbor relationships or route summarization math?
Certsqill’s diagnostic approach maps your knowledge gaps to specific CCNA blueprint objectives. Instead of studying entire domains, you work on the exact concepts that caused your failure.
For example, if you scored poorly in IP Connectivity, Certsqill identifies whether your weakness is:
- Routing table lookup logic
- OSPF area concepts
- EIGRP metric calculations
- Static route configuration
- Default route propagation
This precision matters because studying the wrong subtop
ics wastes weeks and guarantees another failure.
Our CCNA Retake Success Program combines diagnostic assessment with targeted remediation. You get a personalized study plan based on your actual score report, not generic advice. Most importantly, you practice with scenario-based questions that mirror exactly how CCNA tests your knowledge.

Building confidence for your CCNA retake
Failing CCNA often creates a confidence crisis that’s harder to overcome than the actual knowledge gaps. Here’s how to rebuild your confidence systematically:
Start with your strongest domain first. If you scored well in Network Fundamentals but poorly in Automation, begin your retake preparation by reinforcing what you already know. This builds momentum and reminds you that you do understand networking.
Track daily progress on specific skills. Instead of vague goals like “study OSPF,” set measurable targets: “Calculate OSPF cost for three different topologies” or “Explain OSPF LSA types 1-5 without notes.” Check these off daily.
Teach concepts to others (or to yourself out loud). The fastest way to identify remaining knowledge gaps is explaining concepts verbally. If you can’t explain VLAN trunking to someone who’s never heard of VLANs, you don’t understand it well enough for CCNA.
Use simulation environments aggressively. CCNA tests your ability to apply knowledge in realistic scenarios. If you’re only reading about spanning tree but never configuring it, you’ll struggle with simulation questions again.
Time yourself on practice questions. CCNA gives you roughly 1.5 minutes per question. If you’re taking 3-4 minutes to work through subnetting problems during practice, you’ll run out of time on the actual exam regardless of your knowledge level.
Address test anxiety specifically. If you froze up during your first attempt, knowledge isn’t your only problem. Practice relaxation techniques, arrive early to your test center, and develop a question-skipping strategy for difficult items.
Creating accountability for your CCNA retake
One reason many people fail CCNA multiple times is lack of accountability during their retake preparation. You need external verification that you’re actually ready.
Find a study partner who’s also retaking CCNA. Quiz each other weekly on your weakest domains. Schedule regular video calls where you explain concepts to each other without notes.
Join CCNA study groups with specific accountability rules. Look for groups that require members to demonstrate knowledge, not just discuss study materials. Avoid groups focused on brain dumps or shortcuts.
Set up mentorship with someone who passed CCNA recently. They remember exactly what the current exam feels like and can review your practice test scores objectively.
Create external deadlines beyond your retake date. Tell family/friends your retake date and what score you’re targeting. Social pressure helps maintain consistent daily study.
Track study metrics that matter. Don’t just log hours studied. Track specific skills mastered, practice test scores, and speed improvements on calculation-heavy topics.
Schedule weekly assessment calls with yourself. Every Friday, honestly evaluate whether you’re ready to retake CCNA the following week. If not, what specific gaps remain?
Common CCNA retake mistakes that guarantee another failure
After coaching dozens of CCNA retakers, I’ve seen the same mistakes repeatedly:
Mistake 1: Studying everything equally instead of focusing on weak domains. If you scored 85% in Network Fundamentals and 45% in Automation, spending equal time on both domains is inefficient. Focus 80% of your effort on Automation concepts.
Mistake 2: Avoiding simulation questions during practice. Many retakers stick to multiple-choice questions because simulations feel overwhelming. CCNA includes simulation questions worth significant points. You must practice troubleshooting in realistic network environments.
Mistake 3: Memorizing configurations without understanding underlying protocols. You might memorize OSPF configuration commands perfectly but still fail if you don’t understand OSPF neighbor relationships, LSA types, and area concepts.
Mistake 4: Ignoring time management during practice. CCNA is a timed exam. If you consistently exceed time limits during practice, you’ll panic during the actual retake regardless of your knowledge level.
Mistake 5: Using only free study materials for retake preparation. Free materials often lack the depth and current accuracy needed for CCNA retakes. Invest in quality practice tests and labs that mirror actual exam difficulty.
Mistake 6: Retaking too quickly after identifying knowledge gaps. Just because you can reschedule after 15 days doesn’t mean you should. Give yourself adequate time to truly master your weak areas.
FAQ
Q: Can I see which specific questions I got wrong on my failed CCNA attempt?
A: No, Cisco doesn’t provide question-by-question feedback on CCNA results. Your score report shows performance by domain (Network Fundamentals, IP Connectivity, etc.) but not individual question details. This is why analyzing your score report by domain and mapping those to specific blueprint objectives is crucial for retake success.
Q: How many times can I retake CCNA if I keep failing?
A: There’s no limit on CCNA retake attempts, but you must wait 15 days between attempts and pay the full $300 exam fee each time. However, if you fail three times, I strongly recommend stepping back to evaluate whether you need foundational networking training before continuing CCNA attempts.
Q: Will employers know I failed CCNA if I eventually pass?
A: No, employers cannot see failed CCNA attempts. Cisco’s certification verification system only shows current valid certifications, not testing history. Your eventual CCNA certificate won’t indicate how many attempts it took to pass. Many successful network engineers failed CCNA once or twice before passing.
Q: Should I switch from CCNA to Network+ if I failed CCNA?
A: Generally no, unless your failure was due to fundamental networking knowledge gaps (scoring below 50% in Network Fundamentals). Network+ covers different material and won’t directly help you pass CCNA. If you’re committed to Cisco networking career paths, focus on addressing your specific CCNA weak areas rather than switching certifications.
Q: Is it worth hiring a CCNA tutor after failing?
A: Yes, if you can afford it and failed across multiple domains or failed the same domains twice. A qualified tutor can identify knowledge gaps you might miss and provide accountability during retake preparation. However, make sure any tutor you hire has current CCNA certification and actual networking experience, not just tutoring credentials.
