- Performance-based questions appear at the start of the 90-question, 90-minute N10-009 exam and cannot be skipped permanently.
- Network Troubleshooting is the largest domain at 24%, and it is the heaviest source of hands-on PBQ scenarios.
- PBQs test active configuration and diagnosis-subnetting, cable matching, firewall rule ordering-not just recall.
- The passing score is 720 on a 100-900 scale; PBQ partial credit makes every correct action worth earning.
What Performance-Based Questions Actually Are
Every CompTIA Network+ candidate hears the phrase "performance-based questions," but many underestimate how different they feel from a standard four-choice multiple-choice item. A performance-based question (PBQ) drops you into a simulated environment-a drag-and-drop interface, a partial command-line terminal, a network diagram editor, or a configuration screen-and asks you to do something rather than identify a correct answer from a list.
That distinction matters enormously under time pressure. On the current N10-009 exam you have 90 minutes to answer up to 90 questions. PBQs routinely consume three to eight minutes each. Miscalculate how many you face and you can run out of time before reaching the multiple-choice questions that may feel more comfortable.
PBQs are scored individually, and CompTIA awards partial credit on many of them. That means a candidate who correctly identifies three out of four misconfigured firewall rules still earns something toward the 720 passing score, even if the final rule eludes them. This partial-credit model rewards thorough practice over guessing, and it is one reason timed practice tests that simulate PBQ formats have a measurable impact on exam outcomes.
The Main PBQ Formats You Will Encounter
CompTIA does not publish an exhaustive list of every PBQ template, but candidates consistently report five recognizable formats across N10-009 sittings.
Drag-and-Drop Topology and Cable Matching
You are given a set of network devices or cable types and asked to place them correctly in a diagram or match them to the right port or scenario. These questions draw directly from Network Implementation (Domain 2, 20%) topics such as cable categories, connector types, and network device placement. You need to know not just that Cat 6A supports 10 Gbps at 100 meters, but which physical scenario demands it over fiber alternatives.
Simulated Command-Line Interface
A partial terminal window presents a network device prompt-usually modeled after Cisco IOS, a Linux shell, or a Windows command prompt-and asks you to enter commands that diagnose or fix a problem. Expect ipconfig, nslookup, tracert/traceroute, netstat, ping, and basic interface configuration commands. These scenarios appear most frequently in Domain 5: Network Troubleshooting (24%) and Domain 1: Networking Concepts (23%).
Firewall and ACL Configuration
You are shown a partially built access control list or a firewall rule set and asked to add, reorder, or correct rules to match a stated security policy. These questions live squarely in Domain 4: Network Security (14%) and require you to understand implicit deny, rule order precedence, and the difference between stateful and stateless filtering.
Network Diagram Interpretation and Correction
A clickable or labeled network diagram contains one or more faults-wrong IP address ranges, misplaced VLANs, a rogue default gateway-and you must identify and correct them. This format blends Domain 2: Network Implementation (20%) with Domain 3: Network Operations (19%).
Subnetting and IP Address Assignment
Given a network address and a set of requirements (number of hosts per subnet, specific IP ranges reserved), you calculate subnets and assign addresses correctly to simulated devices. Pure subnetting math appears in Domain 1: Networking Concepts, and speed matters-candidates who cannot subnet quickly in their head or on scratch paper lose significant time here.
Key Takeaway
Every PBQ format maps to one or more of the five official N10-009 domains. Build your prep around the domain objectives and the PBQ formats become predictable rather than surprising.
Which Domains Drive the Most PBQs
Understanding the domain weights on N10-009 tells you where CompTIA focuses exam content-and therefore where hands-on simulation is most critical.
Domain 5: Network Troubleshooting (24%)
The largest single domain and the richest source of PBQ scenarios. Candidates must apply a structured troubleshooting methodology, not just recite it.
- Identify the symptom layer (physical, data link, network, transport, application)
- Use CLI tools-ping, traceroute, netstat, nslookup-correctly and interpret their output
- Isolate cable faults, duplex mismatches, MTU issues, and routing failures
- Distinguish wireless interference sources and channel overlap problems
Domain 1: Networking Concepts (23%)
The second-largest domain underpins every PBQ that involves IP addressing, routing protocols, or port/protocol identification.
- IPv4 and IPv6 addressing, CIDR notation, and subnetting calculations
- OSI and TCP/IP model layer functions and where devices operate
- Common ports and protocols (DNS 53, HTTP 80, HTTPS 443, RDP 3389, SSH 22, etc.)
- Routing concepts: static routes, default routes, distance-vector vs. link-state behavior
Domain 2: Network Implementation (20%)
Implementation questions test whether you can deploy correctly, not just describe components.
- Cable types: Cat 5e, Cat 6, Cat 6A, fiber (single-mode vs. multimode), coaxial
- VLAN configuration basics, trunking, and inter-VLAN routing
- Wireless standards (802.11a/b/g/n/ac/ax), frequencies, and channel planning
- Switch port modes: access vs. trunk, STP port states
Domain 3: Network Operations (19%)
Operations PBQs simulate real monitoring and documentation tasks.
- Network monitoring tools: SNMP, syslog, NetFlow, and their use cases
- High availability concepts: redundancy, failover, load balancing
- Documentation: network diagrams, IP address management, change management workflow
Domain 4: Network Security (14%)
The smallest domain still generates PBQs around ACL and firewall rule ordering.
- Authentication protocols: RADIUS, TACACS+, 802.1X
- Attack types: ARP poisoning, VLAN hopping, man-in-the-middle, DoS
- Firewall rule logic and implicit deny behavior
Concrete Topics You Must Be Able to Execute
Reading about subnetting is not the same as completing a subnetting PBQ in under four minutes. Below is a non-exhaustive list of tasks candidates must be able to perform-not just define-to score well on N10-009 PBQs.
| Task | Domain | Common PBQ Format |
|---|---|---|
| Calculate subnet mask and usable host range from CIDR notation | Networking Concepts (23%) | IP assignment simulation |
| Match cable type to physical layer scenario | Network Implementation (20%) | Drag-and-drop |
| Configure basic VLAN and trunk port assignments | Network Implementation (20%) | CLI or diagram correction |
| Interpret ping and traceroute output to isolate a fault | Network Troubleshooting (24%) | CLI simulation |
| Order firewall ACL rules to enforce a stated policy | Network Security (14%) | Rule set editor |
| Identify the correct network monitoring tool for a scenario | Network Operations (19%) | Multiple-choice and drag-and-drop |
| Assign the correct 802.11 standard and channel to a wireless deployment | Network Implementation (20%) | Diagram editor |

How to Approach PBQs During the Exam
Experienced candidates develop a consistent in-exam strategy for PBQs rather than improvising. The following approach is drawn from the structure of the exam itself.
Flag and Return-But Know the Cost
The Pearson VUE delivery platform allows you to flag questions and return to them. PBQs appear at the very beginning of the exam. You can choose to flag each one and tackle multiple-choice questions first, returning to PBQs with remaining time. The risk is real: if a PBQ requires careful work and you only leave yourself ten minutes for three of them, partial credit becomes your ceiling rather than a fallback.
A better approach for most candidates is to spend a maximum of five minutes on each PBQ on the first pass, complete as much as possible, flag it, and then return if time allows after finishing the multiple-choice section.
Read the Scenario Constraints Before Touching the Simulation
Every PBQ includes a scenario description that contains the constraints-IP ranges already in use, specific policies to enforce, device roles that are fixed. Candidates who jump straight into the simulation interface often waste time undoing choices that violated a constraint they missed. Read the full scenario first, note the constraints on your scratch paper, then act.
Use Partial Credit Deliberately
If you cannot complete a PBQ fully, fill in every element you are confident about before moving on. On a firewall rule PBQ with six rules to order, correctly placing four of them still earns partial credit toward your 720 target. Leaving the simulation blank because it felt hard earns zero.
A Domain-Anchored Prep Schedule
Generic study schedules ignore the reality that Network Troubleshooting (24%) and Networking Concepts (23%) together represent nearly half the exam. A schedule that gives equal time to every domain wastes the hours that matter most. The following six-week outline front-loads the heaviest domains and builds PBQ simulation into every week rather than saving it for the end.
Networking Concepts Foundation (Domain 1, 23%)
- Master IPv4 subnetting until you can subnet a /26 in under 90 seconds
- Memorize OSI layer functions and map every common protocol to its layer
- Complete at least 10 subnetting PBQ simulations using timed practice
Network Troubleshooting Core (Domain 5, 24%)
- Practice every major CLI diagnostic command until output interpretation is automatic
- Work through physical layer to application layer troubleshooting scenarios
- Use the practice test platform for timed Domain 5 question sets daily
Network Implementation (Domain 2, 20%)
- Cable types, connector standards, and physical deployment scenarios
- VLAN configuration, 802.11 wireless standards, and STP port states
- Drag-and-drop topology practice with self-made flashcard diagrams
Network Operations and Security (Domains 3 and 4, 19% + 14%)
- SNMP, syslog, NetFlow use cases and when each is appropriate
- Firewall rule ordering logic and implicit deny behavior
- Authentication protocols: RADIUS vs. TACACS+ differences
Full PBQ Simulation Sprint
- Attempt one full timed mock exam per day including PBQ-style questions
- Identify every question missed in Domains 1 and 5 and re-study those objectives specifically
- Review the NETWORK Plus Performance-Based Questions Guide 2026 for annotated PBQ walkthroughs
Weak-Area Consolidation and Exam Logistics
- Focus exclusively on domains where mock exam scores fall below your average
- Confirm Pearson VUE appointment, ID requirements, and delivery method
- Review CEU renewal requirements so you know your post-cert obligations
Registration, Delivery, and What to Expect on Test Day
The N10-009 exam is delivered exclusively through Pearson VUE, either at an authorized test center or via online proctored delivery from your own location. Both formats present identical question content-the PBQs, the simulations, and the multiple-choice questions are the same regardless of delivery channel.
Voucher and Pricing
The U.S. exam voucher is commonly listed around $369, though regional pricing varies. CompTIA periodically offers academic pricing for students and bundles that include study materials. Purchase the voucher directly through CompTIA's store or an authorized reseller, then schedule your appointment through the Pearson VUE portal. Vouchers have expiration dates-do not purchase one before your prep is on track.
Online Proctored Delivery Specifics
If you choose online proctoring, your testing environment will be scanned before the exam begins. You are allowed scratch paper in test center sittings (and an equivalent in some online formats-verify current Pearson VUE policy at time of booking). Scratch paper is valuable specifically for subnetting PBQs; practice doing your subnet calculations on paper rather than mentally to mirror test conditions.
Score Reporting
Your score is reported immediately at the end of the exam at a test center. Online results may take a short period to appear. The 720 passing score sits on a 100-900 scale-a scaled score, meaning CompTIA adjusts for slight variation in question difficulty across exam versions. You will receive a score report identifying performance by domain, which is useful for planning a retake if needed.
Certification Validity and Renewal
Your Network+ certification is valid for three years from the date you pass. Renewal requires earning 30 continuing education units (CEUs) or completing an approved renewal path. For a full breakdown of which activities qualify and how to submit them, see the NETWORK Plus CEU Requirements: How to Renew in 2026 guide.
Frequently Asked Questions
CompTIA does not publish an exact count of PBQs per sitting. The total exam has a maximum of 90 questions delivered in 90 minutes. Candidates consistently report between three and six PBQs per exam, but the number can vary. Budget your time assuming at least four PBQs when planning your exam pacing strategy.
CompTIA uses a scaled scoring model, and PBQs can award partial credit, which means a single PBQ may contribute more points than a single multiple-choice question depending on how many scored elements it contains. Partially completing a PBQ is always better than leaving it blank.
Yes. The Pearson VUE platform allows you to flag questions and return to them before submitting. Many candidates flag PBQs on the first pass and complete multiple-choice questions first. The risk is time: PBQs take longer than standard questions, so ensure you reserve adequate time to return. Some candidates find it less stressful to spend a focused first pass on each PBQ rather than letting anxiety about them accumulate.
Packet Tracer (Cisco's free network simulator), GNS3, and browser-based lab environments all allow you to practice IOS commands and Linux networking commands without physical hardware. Combine simulator practice with timed question sets on our Network+ practice platform to build both the command knowledge and the time management habits the exam demands.
Domain 5: Network Troubleshooting at 24% is the single highest-weighted domain and generates the most PBQ scenarios. If time is severely limited, focus there first, then Domain 1: Networking Concepts at 23%. Together they represent nearly half the exam. Review the NETWORK Plus CEU Requirements: How to Renew in 2026 article so you also understand what happens after you pass.
