Can You Retake CCIE-EI After Failing? Retake Rules Explained (2026)

Failed your CCIE Enterprise Infrastructure exam? You’re not alone. The CCIE-EI has one of the toughest pass rates in the certification world, and most candidates need multiple attempts. The question isn’t whether you can retake it—you can—but when, how much it costs, and how to make your next attempt count.

Direct answer

Yes, you can retake the CCIE-EI after failing. Cisco allows unlimited retake attempts for the CCIE Enterprise Infrastructure exam, but you must wait a mandatory period between attempts. The exact waiting period and retake fees are subject to Cisco’s current policies, which can change. Check Cisco’s official exam page for the most current retake policy as rules can change.

The retake process follows Cisco’s standard exam retake framework, but the CCIE-EI’s unique format—combining both written and lab components—means your retake strategy needs to account for both sections depending on where you failed.

CCIE-EI retake rules: the official policy

Cisco’s CCIE-EI retake policy operates under their broader certification retake framework, but with specific considerations for the CCIE track’s two-part structure.

For the written exam portion (ENCOR 350-401), Cisco typically requires a waiting period between failed attempts. This waiting period has historically ranged from 5 to 30 days depending on the number of previous attempts, but these timeframes can change. The lab exam portion follows similar waiting period requirements.

Check Cisco’s official exam page for the most current retake policy as rules can change because Cisco has adjusted these policies multiple times in recent years, particularly post-COVID when they restructured many certification requirements.

Key points about the official policy:

• Unlimited retake attempts are allowed
• Mandatory waiting periods apply between attempts
• Each retake requires full payment of exam fees
• Your CCIE-EI candidacy doesn’t expire, but written exam scores do have validity periods
• Lab exam eligibility requires a valid written exam pass

The policy treats written and lab portions separately. If you pass the written exam but fail the lab, you only need to retake the lab portion (assuming your written score is still valid). However, if your written exam score expires while you’re attempting the lab, you’ll need to retake both.

How long do you have to wait before retaking CCIE-EI?

The waiting period for CCIE-EI retakes follows Cisco’s tiered approach, which typically increases with each failed attempt. However, the exact timeframes are subject to change and vary by region.

Historically, Cisco has implemented waiting periods such as:

• First retake: Often 5-15 days
• Subsequent retakes: May increase to 30+ days
• Some regions may have different timeframes

Check Cisco’s official exam page for the most current retake policy as rules can change. These waiting periods have been modified several times, and Cisco may implement different policies for different regions or exam types.

The waiting period applies separately to written and lab components. If you fail the ENCOR written exam, you wait the specified period before retaking it. If you fail the lab exam, a separate waiting period applies before you can rebook the lab.

For CCIE-EI specifically, this creates some strategic considerations:

• Written exam retakes can often be scheduled more quickly than lab exams
• Lab exam scheduling depends on availability at Cisco testing centers
• Popular lab locations may have longer booking lead times regardless of your waiting period

Don’t confuse the mandatory waiting period with scheduling availability. Even after your waiting period expires, you might need to wait additional weeks or months for lab exam slots at your preferred testing center.

How much does a CCIE-EI retake cost?

CCIE-EI retakes require paying full exam fees again—there are no retake discounts. The cost structure breaks down by exam component:

Written Exam (ENCOR 350-401): Cisco’s current pricing for the ENCOR exam is typically around $400 USD, but prices vary by region and are subject to change. This is the same fee whether it’s your first attempt or fifth retake.

Lab Exam: The CCIE lab exam fee is significantly higher, typically around $1,600 USD, though pricing varies by region and testing center. Again, this full fee applies to every retake attempt.

Total Retake Costs: If you need to retake both components, you’re looking at roughly $2,000 USD in exam fees alone, plus:

• Travel expenses to lab testing centers
• Accommodation costs for multi-day lab attempts
• Lost productivity from time off work
• Additional study materials or training

The financial impact of retakes is substantial. A candidate who fails the lab exam three times before passing will have spent over $4,800 just in lab exam fees, not including the initial attempt or written exam costs.

Some cost considerations specific to CCIE-EI:

• Written exam can be taken remotely or at local testing centers, minimizing travel costs
• Lab exams require travel to specific Cisco testing centers, which may be far from your location
• Lab exam scheduling often requires booking accommodations well in advance
• Currency fluctuations can affect costs for international candidates

Budget for multiple attempts when planning your CCIE-EI journey. Most successful candidates spend $3,000-5,000+ in total exam fees and related expenses.

How many times can you retake CCIE-EI?

Cisco allows unlimited retake attempts for the CCIE-EI exam. There’s no maximum number of times you can fail and retry, though each attempt requires paying full fees and observing waiting periods.

This unlimited policy is both a blessing and a potential trap. While it means you’ll eventually have the opportunity to pass, it can also lead to:

• Repeated attempts without addressing root cause knowledge gaps
• Escalating financial costs from multiple retakes
• Diminishing confidence with each failed attempt
• Falling into a pattern of “just one more try” without strategic improvement

The reality is that most candidates who eventually pass CCIE-EI do so within their first 3-4 attempts. If you’re approaching your fifth or sixth attempt, it’s worth seriously reassessing your preparation strategy rather than continuing the same approach.

From a practical standpoint, consider these factors:

Financial limits: Each retake costs $1,600+ for the lab alone. Most people have practical budget constraints that effectively limit retake attempts.

Time investment: Preparing for CCIE-EI retakes requires significant time investment. Consider whether that time might be better spent on other career development activities.

Technology evolution: Cisco updates exam blueprints periodically. Taking too long to pass might mean facing updated exam requirements partway through your journey.

Career progression: While pursuing CCIE-EI, you might miss other career opportunities that don’t require the certification.

The unlimited retake policy is designed to support dedicated candidates, not enable endless repetition without improvement. Use it wisely.

What changes between your first and second attempt

Your second CCIE-EI attempt won’t be identical to your first, even if you’re retaking the same exam version. Several factors change between attempts that you need to account for:

Lab Scenarios: The CCIE-EI lab exam uses different scenarios and topologies for each attempt. While the tested domains remain consistent—Network Infrastructure (30%), Software Defined Infrastructure (30%), Transport Technologies and Solutions (20%), and Infrastructure Security and Services (20%)—the specific implementation challenges will vary.

You might encounter different:

• Network topologies and device configurations
• Troubleshooting scenarios and failure points
• Implementation requirements and constraints
• Time pressures based on scenario complexity

Your Knowledge State: Between attempts, your technical knowledge should improve, but other factors might have changed:

• Skills in weak areas may have strengthened
• Confidence might be lower after a failed attempt
• Test anxiety may have increased
• Time management strategies may have evolved

Exam Environment: If significant time passes between attempts:

• Cisco may have updated exam blueprints
• New technologies might be included
• Older technologies might be de-emphasized
• Lab equipment or software versions might change

Strategic Approach: Most candidates adjust their approach after failing:

• Different time allocation strategies for lab sections
• Modified troubleshooting methodologies
• Updated study focus based on identified weak areas
• Changed test-taking tactics

Preparation Materials: Your study resources might change:

• New practice labs or study guides may become available
• Your understanding of effective prep materials improves
• Budget constraints might affect available resources
• Access to lab equipment or simulation tools might change

The key insight is that while you’re taking the “same” exam, both you and the exam have evolved. Your retake preparation should account for these changes rather than simply repeating your original study approach.

How to use the waiting period strategically

The mandatory waiting period between CCIE-EI attempts isn’t just dead time—it’s a strategic opportunity to address specific weaknesses and improve your chances of passing the retake.

Immediate Post-Exam Analysis (Days 1-3): Right after failing, conduct a thorough failure analysis while the experience is fresh:

• Document specific topics where you struggled
• Identify which of the four domains caused the most difficulty
• Note time management issues during the exam
• Record any technical gaps you discovered during the attempt

For CCIE-EI specifically, categorize your struggles by domain:

• Network Infrastructure (30%): Routing protocols, switching technologies, network assurance
• Software Defined Infrastructure (30%): SD-WAN, SD-Access, automation, orchestration
• Transport Technologies and Solutions (20%): MPLS, VPN technologies, QoS
• Infrastructure Security and Services (20%): Network security, infrastructure services

Targeted Study Planning (Days 4-7): Use your failure analysis to create a focused study plan:

• Prioritize the domains where you performed worst
• Identify specific technologies within those domains that need work
• Plan hands-on lab practice for weak areas
• Schedule study time to maximize the waiting period

Hands-On Practice Focus (Remainder of waiting period): The CCIE-EI is heavily practical, so use your waiting time for intensive hands-on practice:

• Build lab scenarios targeting your weak domains
• Practice troubleshooting methodologies for areas you struggled with
• Time yourself on configuration tasks that caused delays
• Work through multiple topology variations

Strategic Considerations:

• If you failed due to Software Defined Infrastructure gaps, focus heavily on SD-WAN and SD-Access implementations
• Network Infrastructure failures often indicate routing protocol or switching issues requiring extensive lab practice
• Transport Technologies struggles usually need deep-dive study into MPLS and VPN concepts
• Infrastructure Security failures require both theoretical study and practical implementation

Don’t just study harder—study smarter. Use the waiting period to address root causes rather than surface-level symptoms of your exam failure.

**Scheduling Your Ret

Scheduling Your Retake:

Once your waiting period ends, scheduling strategy matters significantly for CCIE-EI success. Book your lab retake as soon as you’re eligible—popular testing centers like San Jose, Richardson (Dallas), and Brussels often have 2-3 month waiting lists.

Consider timing strategically:

• Avoid scheduling immediately after major Cisco Live events when demand spikes
• Monday-Wednesday lab slots often have better availability than Friday sessions
• Factor in your preparation timeline when booking—don’t rush just to get an earlier slot

For written exam retakes, scheduling is more flexible since you can test at local Pearson VUE centers or remotely. However, don’t underestimate the ENCOR exam’s difficulty—it requires the same focused preparation as your initial attempt.

Most effective retake preparation strategies

Your CCIE-EI retake preparation should be fundamentally different from your original study approach. Cookie-cutter study plans that worked for initial attempts rarely address the specific gaps that caused your failure.

Target Your Weakest Domain First: Based on your failure analysis, spend 60% of your preparation time on your weakest domain. If Software Defined Infrastructure caused your failure, dedicate extensive time to:

• SD-WAN policy configuration and troubleshooting
• SD-Access fabric implementation and LISP operations
• DNA Center automation workflows
• Cisco ACI fundamentals and policy models

For Network Infrastructure weaknesses, focus intensively on:

• OSPF and EIGRP advanced features and troubleshooting
• BGP path selection and manipulation techniques
• Spanning Tree Protocol variations and optimizations
• Network assurance tools and methodologies

Practice Under Pressure: Time pressure causes many CCIE-EI failures. Your retake preparation must include timed practice sessions that simulate exam conditions:

• Set 8-hour practice sessions matching actual lab duration
• Practice with realistic topologies, not simplified tutorials
• Include break time in your practice to match exam day conditions
• Document your time per task to identify bottlenecks

Focus on Integration, Not Isolation: CCIE-EI tests your ability to integrate multiple technologies, not just configure them individually. Your retake preparation should emphasize:

• Cross-domain scenarios combining routing, switching, and security
• End-to-end service implementation across multiple device types
• Troubleshooting complex multi-vendor environments
• Policy implementation that affects multiple network layers

Practice realistic CCIE-EI scenario questions on Certsqill — with AI Tutor explanations that show exactly why each answer is right or wrong. This targeted practice helps identify knowledge gaps before you encounter them in the actual exam.

Address Fundamentals, Not Just Advanced Topics: Many retake candidates skip fundamentals, assuming they “know the basics.” This is a mistake. CCIE-EI failures often stem from shaky foundational knowledge that breaks down under pressure:

• Review packet flow and forwarding decisions
• Practice basic configuration syntax from memory
• Ensure command recall speed for common operations
• Verify understanding of underlying protocols, not just configuration

Build Systematic Troubleshooting Methodology: Develop and practice a consistent troubleshooting approach for each technology domain:

1. Layer-by-layer analysis: Physical → Data Link → Network → Transport → Application
2. Domain-specific workflows: Different approaches for routing vs. switching vs. security issues
3. Tool utilization: Know when to use show commands, debug options, or monitoring tools
4. Documentation habits: Practice taking notes during troubleshooting that you can reference later

Timing Strategy Refinement: Analyze how you spent time during your failed attempt and adjust:

• Identify tasks that consumed excessive time relative to point value
• Practice rapid elimination of obviously incorrect troubleshooting paths
• Develop time checkpoints throughout the exam (e.g., 25% complete after 2 hours)
• Plan break timing to maintain focus during critical periods

Managing retake anxiety and building confidence

CCIE-EI retakes carry additional psychological pressure that can significantly impact performance. The financial investment, time commitment, and professional stakes create anxiety that didn’t exist during your first attempt.

Reframe the Retake Narrative: Most successful CCIE candidates required multiple attempts. Your retake isn’t a sign of failure—it’s a normal part of the certification process. Industry statistics show that even highly experienced network engineers typically need 2-3 attempts to pass.

Change your internal narrative from “I failed” to “I gathered valuable intelligence.” Your first attempt provided specific information about exam format, question types, time pressures, and knowledge gaps that first-time test takers don’t have.

Build Confidence Through Measurable Progress: Track specific improvements since your last attempt:

• Configuration speed improvements on key tasks
• Reduced troubleshooting time for common scenarios
• Expanded knowledge in previously weak domains
• Better understanding of exam format and expectations

Keep a preparation log documenting daily progress. Seeing concrete evidence of improvement combats the anxiety that you’re not ready for the retake.

Develop Test Day Routines: Reduce exam day anxiety by establishing consistent routines:

• Standardized pre-exam preparation (sleep schedule, nutrition, arrival timing)
• Consistent workspace setup and organization methods
• Predetermined break scheduling and activities
• Emergency de-stress techniques for high-pressure moments

Practice Positive Visualization: Spend time visualizing successful completion of challenging exam scenarios. Mental rehearsal helps reduce anxiety when you encounter similar situations during the actual exam.

Address Imposter Syndrome: Many retake candidates question whether they belong in the CCIE-level conversation. Remember that seeking CCIE-EI certification demonstrates advanced career commitment and technical ambition. The certification process is designed to be challenging—struggling with it doesn’t reflect on your overall competence as a network professional.

Set Realistic Expectations: While you want to pass, don’t create all-or-nothing pressure. Focus on demonstrating improved performance compared to your previous attempt. Even if you need multiple retakes, each attempt should show measurable progress toward your goal.

FAQ: CCIE-EI retake questions

Q: If I pass the ENCOR written exam but fail the CCIE-EI lab, do I need to retake both portions?

A: No, you only need to retake the lab portion if your ENCOR score is still valid. ENCOR exam scores are valid for three years from the pass date. If your ENCOR score expires while you’re attempting the lab exam, you’ll need to retake both the written and lab portions. Plan your lab attempts accordingly to avoid letting your written score expire.

Q: Can I take the CCIE-EI retake at a different testing center than my original attempt?

A: Yes, you can take your retake at any Cisco testing center that offers CCIE-EI lab exams. Popular centers include San Jose (CA), Richardson (TX), Research Triangle Park (NC), Brussels, Beijing, Tokyo, and Sydney. However, scheduling availability varies significantly by location. Some centers have longer waiting lists, so factor location flexibility into your retake planning.

Q: Will my retake exam have the same scenarios and topology as my failed attempt?

A: No, each CCIE-EI lab attempt uses different scenarios and network topologies, even if you’re taking the same exam version. While the tested domains and weightings remain consistent (Network Infrastructure 30%, Software Defined Infrastructure 30%, Transport Technologies 20%, Infrastructure Security 20%), the specific implementation challenges, device configurations, and troubleshooting scenarios will be different.

Q: If Cisco updates the CCIE-EI exam blueprint between my failed attempt and retake, which version do I take?

A: You’ll take whatever exam version is current at the time of your retake. Cisco typically provides 6-12 months notice before implementing blueprint changes, and they publish detailed information about what’s changing. If blueprint updates occur between your attempts, you’ll need to study the new topics and adjust your preparation accordingly. Check Cisco’s learning network for the most current exam blueprint before scheduling your retake.

Q: Can I get any feedback about why I failed to help prepare for my retake?

A: Cisco provides limited feedback through your score report, which shows performance by domain area but doesn’t include specific question details. The score report indicates whether you performed “Below Passing,” “Near Passing,” or “Above Passing” in each tested domain. Use this information to focus your retake preparation on areas where you scored lowest. However, don’t rely solely on the score report—your own analysis of which topics felt challenging during the exam is equally valuable for retake planning.
