Final 7-Day Review Plan and Readiness Checklist
Key Takeaways Explain This Topic AI
The N10-009 blueprint weights domains as Networking Concepts 23%, Implementation 20%, Operations 19%, Security 14%, and Troubleshooting 24%—mirror these in your final week.
Plan for up to 90 questions in 90 minutes (about one minute each) including performance-based questions (PBQs) that appear first.
The last week should drill subnetting, wireless, VLANs, routing, tools, and log interpretation by hand rather than passive rereading.
Readiness is measured by objective coverage, explanation quality, timing, and lab comfort—not by recognizing memorized answers.
On the final day favor light review, command recall, and rest over cramming new material.

Final 7-Day Review Plan
The current CompTIA Network+ N10-009 blueprint weights the five domains as Networking Concepts 23%, Network Implementation 20%, Network Operations 19%, Network Security 14%, and Network Troubleshooting 24% . The exam delivers up to 90 questions in 90 minutes , mixing multiple-choice with performance-based questions (PBQs) , and the passing score is 720 on a 100–900 scale . PBQs usually appear at the start—flag and skip ones that stall you so you protect the roughly one-minute-per-item budget. Your final week should reflect the weighting, with extra time on Troubleshooting (largest domain) and Concepts.
7-Day Plan
- Day Focus Work products
- 7 Baseline and objectives Timed mixed quiz; list weak objectives; rebuild port and subnet tables
- 6 Networking Concepts (23%) OSI, TCP/IP, routing basics, IP addressing, IPv6, DNS, DHCP, NAT, cloud
- 5 Network Implementation (20%) Switching, VLANs, trunks, wireless, routing, cabling, transceivers, diagrams
- 4 Network Operations (19%) Monitoring, documentation, change management, DR, high availability
- 3 Network Security (14%) Segmentation, VPNs, hardening, access control, wireless security, attack types
- 2 Network Troubleshooting (24%) Methodology, tools, logs, route/DNS/DHCP/wireless and performance symptoms
- 1 Light final review Ports, acronyms, command syntax, subnet drills, missed-question notes, rest
- Daily Review Loop
Use the same loop each day:
Review the relevant objective list from the official exam objectives PDF.
Study notes for 45–60 minutes.
Complete hands-on drills or scenario questions.
Explain missed items out loud or in writing.
Add one-line fixes to a missed-question log.
Finish with a short mixed set from older domains so earlier material stays warm.
Missed-Question Log
- Missed item Objective area Error type Fix
- Chose /26 for 70 hosts IP addressing Capacity error /25 = 126 usable; count hosts before picking a mask
- Picked Telnet for admin Security Secure-alternative error Use SSH for secure CLI management
Blamed DNS after a correct lookup Troubleshooting Evidence error Separate name resolution from port reachability
Forgot AP trunk VLAN Wireless implementation Design-dependency error SSID-to-VLAN needs the AP uplink and firewall policy aligned
Readiness Checklist
You are in good shape when you can do the following without notes:
Identify the OSI layer most associated with a symptom.
Subnet /24 through /30 networks quickly and accurately.
Explain why VLSM allocates the largest networks first.
Match common ports to services and their secure alternatives.
Build a simple VLAN, trunk, gateway, DHCP, and firewall-policy table.
Choose Wi-Fi bands, channels, and security modes for a scenario.
Select copper, fiber, connectors, and optics by distance and speed.
Use ipconfig, ip, ping, traceroute, nslookup, dig, arp, netstat, ss, tcpdump, and Wireshark in the right context.
Interpret a small set of logs or counters and choose the next step.
Explain why an answer is right and why the nearest distractor is wrong.
PBQ Readiness Drills
- Drill Target time Passing standard
- VLSM table for five networks 10 min No overlap, correct gateways and masks
- VLAN and firewall-policy table 12 min Guest isolated, required services allowed, final deny present
- Wireless troubleshooting scenario 8 min Identifies RF, VLAN, DHCP, or authentication root cause
- Route and service triage 10 min Separates DNS, route, port, firewall, and application evidence
- Final Day Rules
Do not learn an entirely new topic unless it is a small, high-yield gap.
Rework missed questions by objective, not by answer letter.
Review tables for ports, cabling, optics, Wi-Fi, commands, and acronyms.
Do a few subnetting problems to stay sharp.
Confirm two valid IDs, your appointment time, and online-proctor or test-center requirements.
Stop heavy study early enough to sleep.
Exam-Day Timing and PBQ Strategy
With up to 90 items in 90 minutes, your budget is about one minute per question, but PBQs—drag-and-drop, simulated CLI, diagram labeling—can swallow five minutes each. They cluster at the start. The proven approach is to skim the first PBQs, complete any you can finish in under two minutes, then flag the rest and move into the multiple-choice bank where you bank quick points. Return to flagged PBQs with your remaining time. Because the score scales from 100 to 900 with a 720 cutoff, leaving items blank is never optimal: there is no penalty for guessing, so eliminate distractors and answer every question before time expires.
Interpreting Your Readiness Signals
Treat practice scores as diagnostic, not predictive. A single 85% on a familiar question pool does not equal exam readiness if you cannot explain the wrong answers. Stronger signals are: finishing a 90-question timed set within 75 minutes with time to revisit flags; scoring consistently above the low-80s across multiple fresh pools; and being able to verbalize why each distractor is wrong. Map weak pools back to the blueprint—if Troubleshooting (24%) and Concepts (23%) are soft, those two domains alone are nearly half the exam, so they earn priority over Security (14%).
The goal of the final week is to convert recognition into reasoning, because PBQs and scenario stems reward the candidate who can apply a method, not recall a fact.
Common Traps
Spending the final week only rereading notes without doing scenarios.
Ignoring Troubleshooting because isolated facts feel easier to review.
Measuring readiness by recognizing answers instead of explaining reasoning.
Memorizing port numbers without knowing what their failure looks like.
Practicing subnetting without checking broadcast and overlap.
Cramming late enough that attention and timing suffer on exam day.
