CompTIA Network+ Practice Test for Subdomain 2.3 #01

Question 1

A wireless network engineer at a manufacturing plant is deploying multiple access points across the production floor. To prevent co-channel interference between adjacent APs operating in the 2.4 GHz band, the engineer must select channels that do not overlap with one another. Which set of channels satisfies this requirement?

A. 1, 5, and 9 B. 1, 6, and 11 C. 2, 7, and 12 D. 1, 3, and 6

Question 2

A network administrator at a law firm is upgrading the wireless infrastructure and wants to deploy the latest encryption standard that provides individualized data encryption for all clients, including those connecting to open networks through Opportunistic Wireless Encryption (OWE). Which wireless security protocol should the administrator configure?

A. WEP B. WPA C. WPA2 D. WPA3

Question 3

A technician is deploying 50 access points across a large hospital campus. The IT team requires centralized management of all APs from a single platform, including firmware updates, configuration pushes, and policy enforcement. The APs themselves should offload control-plane decisions to a central device. Which access point architecture should the technician deploy?

A. Autonomous access points B. Lightweight access points C. Ad hoc access points D. Repeater access points

Question 4

A junior network engineer is reviewing a wireless site survey report and notices that multiple access points share the same SSID but each has a unique BSSID. The engineer is asked to explain what the BSSID represents in the context of the wireless network. Which of the following correctly describes the BSSID?

A. The common network name broadcast by all access points in the wireless infrastructure B. The MAC address of an individual access point's radio interface C. The encryption passphrase shared among all access points in the extended service set D. The VLAN tag assigned to wireless management traffic on the distribution switch

Question 5

Users at a corporate headquarters report that their laptops frequently maintain a weak connection to a distant access point instead of roaming to a nearby AP with a stronger signal. Both nearby and distant APs support 2.4 GHz and 5 GHz. The wireless team enables a controller feature that automatically guides capable dual-band clients toward the less congested, higher-throughput frequency band. Which feature did the team enable?

A. Roaming aggressiveness tuning B. Band steering C. SSID suppression D. Dynamic frequency selection (DFS)

Question 6

A coffee shop owner wants to provide free wireless internet access to customers but requires that each guest view and accept an acceptable use policy before being allowed to browse the internet. The owner asks the IT consultant which wireless feature should be configured to enforce this requirement. Which feature should the consultant recommend?

A. WPA2-Enterprise with RADIUS authentication B. MAC address filtering on the access point C. Captive portal D. Hidden SSID configuration

Question 7

A company's security policy requires that wireless clients be authenticated against Active Directory credentials before gaining network access, rather than using a shared passphrase distributed to all employees. The wireless administrator configures the APs to pass authentication requests to a centralized authentication server. Which authentication method is the administrator implementing?

A. Pre-shared key (PSK) authentication B. WPA2-Personal C. WPA2-Enterprise (802.1X) D. Open authentication with SSID filtering

Question 8

A network engineer at an outdoor stadium is planning the wireless deployment for a large open seating bowl. The team wants to install a small number of access points positioned at the center of the venue that each provide broad, 360-degree horizontal coverage across the entire seating area without requiring precise directional alignment. Which antenna type best meets this requirement?

A. Yagi antenna B. Parabolic dish antenna C. Omnidirectional antenna D. Patch antenna

Question 9

An organization is deploying Wi-Fi 6E access points in a high-density conference center. The wireless team expects that clients using Wi-Fi 6E will benefit from access to additional clean, uncongested spectrum that is not available on traditional 2.4 GHz or 5 GHz deployments. Which frequency band does Wi-Fi 6E extend support into?

A. 900 MHz B. 3.6 GHz C. 6 GHz D. 60 GHz

Question 10

A wireless engineer at a retail chain is configuring 5 GHz access points in a multi-tenant office building. During the site survey, the engineer confirms that the APs must automatically detect radar signals and switch to a clear channel to avoid interfering with licensed radar systems. The APs must also adjust transmit power to meet local regulatory limits. Which 802.11 amendment defines these two regulatory compliance mechanisms?

A. 802.11r B. 802.11k C. 802.11h D. 802.11ac
