CompTIA Network+ Practice Test for Subdomain 2.3 #02

Welcome to today’s CompTIA Network+ practice test!

This practice test uses our new UI!

Today’s practice test is based on Subdomain 2.3 (Given a scenario, select and configure wireless devices and technologies) from the CompTIA Network+ N10-009 objectives.

This beginner-level practice test is inspired by the CompTIA Network+ (N10-009) exam and is designed to help you reinforce key networking concepts on a daily basis.

These questions are not official exam questions, nor are they brain dumps, but they reflect topics and scenarios relevant to the Network+ certification. Use them to test your knowledge, identify areas for improvement, and build daily cybersecurity habits.

CompTIA Network+ Practice Test for Subdomain 2.3 #02

10 questions • Single best answer

Question 1

A wireless site survey engineer at a financial services firm reviews client association data and notices that most dual-band devices are connecting to the 2.4 GHz band even though the 5 GHz band is available and far less congested. The firm wants to improve performance without requiring users to manually select a band. Which access point feature should the engineer enable to address this behavior?

A. SSID suppression to hide the 2.4 GHz network from clients B. Band steering to encourage capable dual-band clients to associate with the 5 GHz band C. Channel bonding to increase the throughput of the 2.4 GHz band D. Beamforming to direct 2.4 GHz signal away from congested areas

Question 2

A network technician is deploying six wireless access points in a large single-story warehouse to provide full coverage with minimal co-channel interference. All APs will operate on the 2.4 GHz band. Adjacent APs must not share overlapping channels. Which set of channels satisfies this requirement for the 2.4 GHz band?

A. Channels 1, 4, and 8 B. Channels 1, 6, and 11 C. Channels 2, 7, and 12 D. Channels 1, 5, and 10

Question 3

A security engineer at a law firm is revising the wireless security policy to require stronger protection against offline dictionary attacks on Wi-Fi credentials. The existing access points support both WPA2 and WPA3. The engineer needs to select the protocol that replaces the four-way handshake with a method that does not expose the password hash to offline brute-force attacks. Which protocol meets this requirement?

A. WPA2-Personal with a complex 20-character passphrase B. WPA2-Enterprise using 802.1X with a RADIUS server C. WPA3-Personal using Simultaneous Authentication of Equals (SAE) D. WEP with 128-bit key encryption

Question 4

An enterprise is deploying 200 wireless access points across eight office buildings and requires centralized management, consistent security policy enforcement, and seamless Layer 2 roaming between APs. The network team must choose the appropriate access point architecture for this scale of deployment. Which AP model and management approach should be selected?

A. Autonomous access points managed individually through the CLI of each device B. Lightweight access points centrally managed by a wireless LAN controller (WLC) C. Ad hoc wireless nodes configured peer-to-peer on each floor without infrastructure D. Standalone mesh nodes that self-organize without any centralized control plane

Question 5

The IT team at a regional hospital is configuring a new wireless network for clinical staff. The hospital's security policy requires that every user authenticate with unique credentials tied to their Active Directory account rather than a shared passphrase, and that a failed credential attempt on one account does not compromise access for other users. Which authentication method satisfies this requirement?

A. WPA2-Personal with a long, randomly generated pre-shared key distributed to all staff B. Open authentication combined with MAC address filtering for each staff device C. WPA2-Enterprise using 802.1X with a RADIUS server integrated with Active Directory D. WPA3-Personal with a unique passphrase per VLAN

Question 6

A hotel network administrator is setting up a guest wireless SSID that requires visitors to read and accept the terms of service before accessing the internet. When a guest connects and opens a browser, they should be automatically redirected to the acceptance page regardless of the URL they attempt to visit. Which feature should the administrator configure on the guest SSID to implement this behavior?

A. A VLAN on the guest SSID to isolate guest traffic from internal systems B. MAC address filtering to control which devices can associate with the guest SSID C. A captive portal that intercepts HTTP requests and redirects guests to the terms of service page D. WPA3-Enterprise authentication requiring certificate validation before internet access

Question 7

A network engineer is deploying wireless coverage across a large outdoor sports complex where running Ethernet cabling to every AP location is cost-prohibitive. The access points must forward client traffic back to the wired network by relaying it through neighboring APs without a wired backhaul at each node. Which wireless network type is designed for this deployment scenario?

A. Infrastructure mode with all APs connected directly to a central controller via Ethernet B. Ad hoc mode with direct peer-to-peer connections between client devices C. Point-to-point wireless bridge between two fixed buildings D. Mesh network where APs use a wireless backhaul to relay traffic to the wired network

Question 8

A wireless engineer is troubleshooting poor Wi-Fi performance in a high-density office building where a spectrum scan reveals dozens of neighboring SSIDs in the 5 GHz band. The enterprise APs are currently configured with 80 MHz channel width. The engineer wants to reduce the likelihood of adjacent-channel interference with neighboring networks while keeping the APs on 5 GHz. Which configuration change is most appropriate?

A. Switch all APs to the 2.4 GHz band to take advantage of its longer range B. Reduce the channel width from 80 MHz to 20 or 40 MHz to use fewer overlapping spectrum resources C. Enable band steering to push all clients to the 6 GHz band automatically D. Increase the transmit power on all APs to overcome interference from neighboring networks

Question 9

A wireless analyst reviewing client connection logs notices that all access points at a corporate campus share the same SSID name, but each AP presents a unique identifier in the association table that corresponds exactly to the AP's physical MAC address. A client roaming between APs changes this identifier while the SSID remains constant. Which wireless identifier is the client changing as it moves between APs?

A. ESSID, which is the common network name shared across all APs in the extended service set B. BSSID, which is the MAC address of the specific AP radio the client is currently associated with C. SSID, which changes as the client associates with different physical access points D. VLAN tag, which is reassigned by the controller when the client roams to a new AP

Question 10

A network administrator is deploying new 5 GHz access points near a coastal weather monitoring facility. A regulatory compliance review notes that the wireless equipment must be capable of detecting active radar systems operating in the same frequency range and automatically vacating those frequencies to avoid interference. Which 802.11 mechanism provides this radar detection and automatic channel switching capability?

A. 802.11r, which accelerates client roaming between access points using fast BSS transition B. 802.11k, which provides radio resource measurement to assist clients in selecting the best AP C. 802.11h, which defines Transmit Power Control (TPC) and Dynamic Frequency Selection (DFS) for radar avoidance D. 802.11v, which enables network-assisted client power savings and BSS transition management
