This free CompTIA Network+ practice test gives you 10 exam-style N10-009 questions across all five domains, each with the correct answer and a short explanation so you can check your reasoning before test day.<\/div>\n<p>A CompTIA Network+ practice test is the quickest way to expose the gap between what you think you know and what the N10-009 exam actually asks. These free Network+ questions\u201410 original, exam-style items, two from each of the five domains\u2014come with the correct answer and a one- to two-sentence explanation you reveal on demand. Treat this N10-009 practice test as a diagnostic: benchmark your readiness, then aim your study at the objectives where you slip. First, the format.<\/p>\n<h2>CompTIA Network+ N10-009 exam format<\/h2>\n<p>Per CompTIA, the Network+ N10-009 exam contains a maximum of 90 questions and gives you 90 minutes to finish. It mixes multiple-choice questions with performance-based questions (PBQs) that drop you into simulated consoles to configure or troubleshoot. Passing requires a scaled score of 720 on a 100\u2013900 scale. Because scoring is scaled and PBQs weigh more than single multiple-choice items, 720 does not translate to a flat 80% of questions correct. CompTIA sets no mandatory prerequisites but recommends the A+ certification and 9\u201312 months of hands-on networking experience. You can sit the exam at a Pearson VUE test center or online with a proctor, and the certification stays valid for three years, renewable through CompTIA&#8217;s continuing-education program. N10-009 launched in June 2024 and emphasizes current priorities: SDN, SASE, zero trust, IPv6, and cloud connectivity.<\/p>\n<p>The exam splits into five weighted domains, per CompTIA:<\/p>\n<table>\n<thead>\n<tr>\n<th>N10-009 domain<\/th>\n<th>Exam weight<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>1.0 Networking Concepts<\/td>\n<td>23%<\/td>\n<\/tr>\n<tr>\n<td>2.0 Network Implementation<\/td>\n<td>20%<\/td>\n<\/tr>\n<tr>\n<td>3.0 Network Operations<\/td>\n<td>19%<\/td>\n<\/tr>\n<tr>\n<td>4.0 Network Security<\/td>\n<td>14%<\/td>\n<\/tr>\n<tr>\n<td>5.0 Network Troubleshooting<\/td>\n<td>24%<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>What each domain covers:<\/p>\n<ul>\n<li><strong>Networking Concepts (23%):<\/strong> the OSI model, ports and protocols, IP addressing and subnetting, topologies, transceivers, and cloud connectivity.<\/li>\n<li><strong>Network Implementation (20%):<\/strong> configuring routers, switches, and firewalls; VLANs and routing; wireless standards; and structured cabling.<\/li>\n<li><strong>Network Operations (19%):<\/strong> documentation, monitoring with SNMP and logs, high availability, and disaster-recovery metrics such as RTO and RPO.<\/li>\n<li><strong>Network Security (14%):<\/strong> the CIA triad, common attacks, access control (802.1X, NAC), and device hardening.<\/li>\n<li><strong>Network Troubleshooting (24%):<\/strong> the CompTIA methodology plus cable, wireless, and connectivity tools like TDRs and protocol analyzers.<\/li>\n<\/ul>\n<p>Troubleshooting (24%) and Networking Concepts (23%) carry the most weight, so budget study time toward them. The quiz below draws two questions from each domain.<\/p>\n<h2>Free CompTIA Network+ practice test: 10 N10-009 questions<\/h2>\n<p>Read each item, choose A\u2013D, then expand the answer to verify. These Network+ practice questions mirror the phrasing and reasoning of the real objectives\u2014no login, no fluff.<\/p>\n<ol class=\"qz\">\n<li>\n<p class=\"q\">1. A router forwards traffic between two different IP subnets. At which OSI layer does it make that forwarding decision?<\/p>\n<p class=\"opt\">A) Layer 1 \u2013 Physical<br \/>B) Layer 2 \u2013 Data Link<br \/>C) Layer 3 \u2013 Network<br \/>D) Layer 4 \u2013 Transport<\/p>\n<details>\n<summary>Reveal answer &amp; explanation<\/summary>\n<p><strong>Correct: C.<\/strong> Routers forward based on logical IP addresses, which live at the Network layer (Layer 3). Switches, by contrast, forward frames using MAC addresses at Layer 2.<\/p>\n<\/details>\n<\/li>\n<li>\n<p class=\"q\">2. A host is configured with 192.168.10.100 and a subnet mask of 255.255.255.192 (\/26). What is its network (subnet) address?<\/p>\n<p class=\"opt\">A) 192.168.10.0<br \/>B) 192.168.10.64<br \/>C) 192.168.10.96<br \/>D) 192.168.10.128<\/p>\n<details>\n<summary>Reveal answer &amp; explanation<\/summary>\n<p><strong>Correct: B.<\/strong> A \/26 mask has a block size of 64, so subnets fall at .0, .64, .128, and .192. The address .100 sits in the .64\u2013.127 range, making 192.168.10.64 the network address.<\/p>\n<\/details>\n<\/li>\n<li>\n<p class=\"q\">3. Two switches share redundant links, forming a physical loop. Which protocol blocks the redundant path to prevent a Layer 2 broadcast storm?<\/p>\n<p class=\"opt\">A) LACP<br \/>B) VRRP<br \/>C) STP<br \/>D) OSPF<\/p>\n<details>\n<summary>Reveal answer &amp; explanation<\/summary>\n<p><strong>Correct: C.<\/strong> Spanning Tree Protocol (802.1D) detects loops and puts redundant ports into a blocking state. LACP aggregates links, VRRP provides gateway redundancy, and OSPF is a Layer 3 routing protocol.<\/p>\n<\/details>\n<\/li>\n<li>\n<p class=\"q\">4. An organization wants access points that can use the 6 GHz band to escape congestion. Which wireless standard supports 6 GHz?<\/p>\n<p class=\"opt\">A) 802.11n (Wi-Fi 4)<br \/>B) 802.11ac (Wi-Fi 5)<br \/>C) 802.11ax (Wi-Fi 6E)<br \/>D) 802.11a<\/p>\n<details>\n<summary>Reveal answer &amp; explanation<\/summary>\n<p><strong>Correct: C.<\/strong> 802.11ax operating as Wi-Fi 6E adds the 6 GHz band. Wi-Fi 5 (ac) tops out at 5 GHz, and Wi-Fi 4 (n) uses only the 2.4 and 5 GHz bands.<\/p>\n<\/details>\n<\/li>\n<li>\n<p class=\"q\">5. In a business continuity plan, which metric defines the maximum amount of data\u2014expressed as a point in time\u2014an organization can afford to lose?<\/p>\n<p class=\"opt\">A) RTO<br \/>B) RPO<br \/>C) MTTR<br \/>D) MTBF<\/p>\n<details>\n<summary>Reveal answer &amp; explanation<\/summary>\n<p><strong>Correct: B.<\/strong> The Recovery Point Objective (RPO) sets how far back your last usable recovery point can be, which drives backup frequency. RTO defines how fast service must return; MTTR and MTBF measure repair time and reliability.<\/p>\n<\/details>\n<\/li>\n<li>\n<p class=\"q\">6. A monitoring server must receive an immediate, unsolicited alert when a switch&#8217;s CPU crosses a threshold. Which SNMP mechanism sends it?<\/p>\n<p class=\"opt\">A) SNMP GET<br \/>B) SNMP trap<br \/>C) MIB walk<br \/>D) Syslog facility<\/p>\n<details>\n<summary>Reveal answer &amp; explanation<\/summary>\n<p><strong>Correct: B.<\/strong> An SNMP trap is an agent-initiated, asynchronous notification pushed to the management station. A GET is a manager-initiated poll, and the MIB is the structured database of managed objects.<\/p>\n<\/details>\n<\/li>\n<li>\n<p class=\"q\">7. An attacker on the LAN sends forged ARP replies mapping the default gateway&#8217;s IP to the attacker&#8217;s MAC address, intercepting traffic. What is this attack?<\/p>\n<p class=\"opt\">A) DNS poisoning<br \/>B) VLAN hopping<br \/>C) ARP spoofing (on-path)<br \/>D) Rogue DHCP<\/p>\n<details>\n<summary>Reveal answer &amp; explanation<\/summary>\n<p><strong>Correct: C.<\/strong> ARP spoofing (poisoning) binds the attacker&#8217;s MAC to a legitimate IP, enabling an on-path (man-in-the-middle) attack. Dynamic ARP Inspection (DAI) is a standard mitigation on managed switches.<\/p>\n<\/details>\n<\/li>\n<li>\n<p class=\"q\">8. Which IEEE standard provides port-based network access control, requiring a supplicant to authenticate through an authenticator to a RADIUS server before the switchport forwards traffic?<\/p>\n<p class=\"opt\">A) 802.1Q<br \/>B) 802.3af<br \/>C) 802.1X<br \/>D) 802.11i<\/p>\n<details>\n<summary>Reveal answer &amp; explanation<\/summary>\n<p><strong>Correct: C.<\/strong> 802.1X defines port-based network access control using a supplicant, authenticator, and authentication (RADIUS) server. 802.1Q is VLAN tagging, and 802.3af is Power over Ethernet.<\/p>\n<\/details>\n<\/li>\n<li>\n<p class=\"q\">9. Per CompTIA&#8217;s troubleshooting methodology, what is the first step when addressing a network issue?<\/p>\n<p class=\"opt\">A) Establish a theory of probable cause<br \/>B) Identify the problem<br \/>C) Test the theory to determine the cause<br \/>D) Document findings and outcomes<\/p>\n<details>\n<summary>Reveal answer &amp; explanation<\/summary>\n<p><strong>Correct: B.<\/strong> CompTIA&#8217;s methodology begins with &#8220;identify the problem&#8221;\u2014gather information, question users, and note recent changes. Establishing a theory of probable cause is step two; documentation is the final step.<\/p>\n<\/details>\n<\/li>\n<li>\n<p class=\"q\">10. A technician must find the distance to a break in a copper cable run buried inside a wall. Which tool reports that distance to the fault?<\/p>\n<p class=\"opt\">A) Tone generator and probe<br \/>B) Time-domain reflectometer (TDR)<br \/>C) Loopback plug<br \/>D) Light meter<\/p>\n<details>\n<summary>Reveal answer &amp; explanation<\/summary>\n<p><strong>Correct: B.<\/strong> A TDR sends a signal down the cable and measures reflections to calculate the distance to a break or impedance fault. A tone generator traces cables, while a loopback plug tests a single port.<\/p>\n<\/details>\n<\/li>\n<\/ol>\n<p>Tally your score. Eight or more correct signals solid readiness; five to seven means you should target specific weak domains; below five means it&#8217;s time for structured study before you book the exam.<\/p>\n<h2>How to use practice tests to pass N10-009<\/h2>\n<p>A practice test is a diagnostic, not a memorization drill. Score it, then let the results steer weeks of focused study:<\/p>\n<ul>\n<li><strong>Sort every miss by domain.<\/strong> Map each wrong answer to its N10-009 objective and rebuild the underlying concept before you retest, rather than memorizing the specific question.<\/li>\n<li><strong>Read every explanation\u2014even for correct answers.<\/strong> Confirm you chose the right option for the right reason, not a lucky guess that will fail on a reworded item.<\/li>\n<li><strong>Space your repetitions.<\/strong> Short, frequent sessions across several weeks beat one long cram; spaced retrieval moves facts into durable memory.<\/li>\n<li><strong>Do the labs.<\/strong> Subnetting, VLANs, and troubleshooting are muscle memory. Configure a switch, capture packets, and break things in a lab so performance-based questions feel routine.<\/li>\n<li><strong>Simulate exam day.<\/strong> Once you clear roughly 90% on domain quizzes, take a full-length, timed run to build the stamina that 90 questions in 90 minutes demands.<\/li>\n<\/ul>\n<p>Keep the scaled 720\/900 pass mark in mind: answer confidently across all five domains rather than mastering one and neglecting another, because a single overall score decides the result.<\/p>\n<h2>Train for N10-009 with Boost eLearning<\/h2>\n<p>Practice questions expose gaps; structured training closes them.
