Question 1

A large conference center needs to provide Wi-Fi for 500 attendees. The IT team installs multiple 802.11ax access points. During the event, attendees report slow speeds and frequent reconnections. Analysis shows many clients are on the same channel despite multiple APs. Which advanced feature should be configured to distribute clients more evenly?

Choose an answer to begin — your selection is scored in the full session.

Accepted Answer

Configure all APs to use the same SSID and enable band steering and load balancing.. Band steering and load balancing are advanced features designed to distribute clients evenly across access points and frequency bands. Band steering encourages dual-band clients to use the less congested 5 GHz band, while load balancing monitors AP utilization and steers new clients to less loaded APs. This directly addresses the problem of many clients clustering on the same channel despite multiple APs being available.

Answer

Enable WPA3-Enterprise for all SSIDs.

Answer

Set each AP to a different SSID and instruct users to connect to the least crowded one.

Answer

Reduce the beacon interval on all APs to 50 ms.

Question 2

A user reports that their laptop can see multiple Wi-Fi networks but cannot connect to any of them. Other devices in the same location connect without issue. What is the most likely cause?

Accepted Answer

The laptop has an incorrect or outdated Wi-Fi password saved for the networks.. The laptop can see multiple Wi-Fi networks (indicating the wireless adapter is functional and scanning is successful) but fails to connect to any of them. This points to a common credential mismatch issue: if the saved password for a network is incorrect or outdated, the 4-way handshake (WPA2/WPA3) will fail, preventing association even though the SSID is visible. Other devices connecting successfully rules out router-side problems.

Answer

The laptop's wireless adapter is disabled in Device Manager.

Answer

The Wi-Fi router is out of range.

Answer

The laptop's Bluetooth is interfering with Wi-Fi.

Question 3

A multinational corporation has offices in New York, London, and Tokyo. They need a private, dedicated network to connect all offices with high reliability and low latency. Which network type should be implemented?

Accepted Answer

Wide Area Network (WAN). A Wide Area Network (WAN) is the correct choice because it is designed to connect geographically dispersed locations, such as offices in different cities or countries, over a large area. WANs provide private, dedicated circuits (e.g., MPLS, leased lines) that offer high reliability and low latency, meeting the multinational corporation's requirements for interconnecting New York, London, and Tokyo.

Answer

Local Area Network (LAN)

Answer

Metropolitan Area Network (MAN)

Answer

Personal Area Network (PAN)

Question 4

A technician is setting up a Windows 10 tablet for a field worker who needs to use a legacy line-of-business (LOB) app that only runs in 32-bit mode. The tablet has a 64-bit processor and Windows 10 Pro. How should the technician ensure the app runs correctly?

Accepted Answer

Install the app normally; 32-bit apps are supported on 64-bit Windows.. Windows 10 64-bit includes the Windows-on-Windows 64-bit (WOW64) subsystem, which provides full compatibility for 32-bit applications without any additional configuration. Since the legacy LOB app is a 32-bit x86 application, it will run natively under WOW64 on the 64-bit version of Windows 10 Pro. No virtualization, compatibility mode changes, or separate 64-bit version is required.

Answer

Install the app in a virtual machine running 32-bit Windows.

Answer

Enable Windows 8 compatibility mode for the app.

Answer

Download and install the 64-bit version of the app from the vendor.

Question 5

A customer brings in a smartphone with a cracked glass digitizer that still responds to touch, but the LCD underneath is intact. They want the cheapest repair that restores full functionality. Which component should you replace?

Accepted Answer

Replace only the digitizer.. The digitizer (touch layer) is the only damaged component; the LCD is intact and the touch function still works. Replacing only the digitizer restores full functionality at the lowest cost, as it avoids the expense of replacing the undamaged LCD panel.

Answer

Replace the entire screen assembly (LCD + digitizer).

Answer

Replace only the LCD panel.

Answer

Apply a glass screen protector and ignore the crack.

Question 6

A user reports that their Android tablet frequently crashes when using a specific note-taking app, but other apps work fine. They have already cleared the app cache and data. What should you do next to resolve the issue?

Accepted Answer

Uninstall and reinstall the note-taking app.. Since the issue is isolated to a single app and persists after clearing cache and data, the next logical step is to uninstall and reinstall the app. This replaces the app's APK and all its associated files, eliminating any corrupted installation or misconfigured permissions that clearing data did not fix. A factory reset or hardware replacement is premature when the problem is application-specific.

Answer

Perform a factory reset on the tablet.

Answer

Disable the tablet's antivirus software.

Answer

Replace the tablet's battery.

Question 7

A user reports that their Android phone's battery drains quickly after installing a new social media app. The phone worked fine before. What is the most efficient first troubleshooting step?

Accepted Answer

Check the app's permissions and disable background activity.. The most efficient first step is to check the app's permissions and disable background activity because the new social media app is likely consuming battery by running background services (e.g., location polling, push sync, or wake locks). This approach isolates the problem without removing the app, allowing you to confirm the cause before taking further action. It aligns with the CompTIA A+ troubleshooting methodology of identifying the most probable cause first.

Answer

Uninstall the social media app immediately.

Answer

Perform a factory reset of the device.

Answer

Update the phone's operating system.

Question 8

A technician is asked to set up a network for a new branch office that will connect back to the main headquarters using a leased line. The branch has 50 employees who need access to centralized databases and email. Which network type best describes the branch office's internal network?

Accepted Answer

Local area network (LAN). The branch office's internal network connects 50 employees within a single physical location, providing shared access to local resources like printers and servers. This fits the definition of a Local Area Network (LAN), which operates over a limited geographic area and uses high-speed technologies such as Ethernet (IEEE 802.3) and Wi-Fi (IEEE 802.11). The leased line to headquarters is a separate WAN connection, but the internal network itself remains a LAN.

Answer

Wide area network (WAN)

Answer

Metropolitan area network (MAN)

Answer

Personal area network (PAN)

Question 9

A user reports that their laptop's built-in display shows distorted colors and horizontal lines, but when they connect an external monitor via VGA, the external display works perfectly. What is the most likely cause?

Accepted Answer

The laptop's LCD panel or its video cable is damaged. The external monitor works perfectly via VGA, which bypasses the laptop's internal LCD panel and its video cable. Distorted colors and horizontal lines on the built-in display, combined with a flawless external display, isolate the fault to the LCD panel assembly or the LVDS/eDP cable connecting the panel to the motherboard. The GPU and driver are shared between both displays, so they cannot be the cause when the external display functions correctly.

Answer

The laptop's GPU is failing

Answer

The VGA cable is defective

Answer

The display driver is corrupt

Question 10

A technician is configuring a wireless network for a high-density environment such as a conference hall. The network must support hundreds of simultaneous connections with minimal interference. Which configuration will best achieve this?

Accepted Answer

Deploy multiple access points with reduced transmit power and non-overlapping channels. In a high-density environment like a conference hall, deploying multiple access points with reduced transmit power and non-overlapping channels (e.g., 1, 6, 11 for 2.4 GHz) minimizes co-channel interference and allows efficient frequency reuse, supporting hundreds of simultaneous connections. This design increases overall capacity by creating smaller, manageable cells that reduce contention and improve throughput per client.

Answer

Use a single high-power access point to cover the entire hall

Answer

Disable the 5 GHz band to reduce complexity

Answer

Enable WPS for faster client connections

Question 11

A technician is installing a new network in a school and must run cables through air handling plenums. What type of cable jacket is required for this installation?

Accepted Answer

Plenum-rated jacket. Plenum-rated jackets are required for cables installed in air handling plenums because they are made of low-smoke, low-flame materials (such as FEP or PFA) that do not emit toxic fumes or support combustion in the event of a fire. This complies with fire safety codes like the National Electrical Code (NEC) Article 725 and ensures that the air circulation system does not spread smoke or flames throughout the building.

Answer

PVC jacket

Answer

Shielded jacket

Answer

Riser-rated jacket

Question 12

A user's laptop frequently disconnects from a 5 GHz Wi-Fi network when they move to a room two walls away from the access point. The 2.4 GHz network remains stable throughout the office. Which of the following best explains this behavior?

Accepted Answer

The 5 GHz signal has weaker penetration through walls.. The 5 GHz band uses higher frequency radio waves that attenuate more rapidly when passing through solid obstacles like walls, resulting in weaker signal penetration compared to the 2.4 GHz band. This physical property causes the laptop to disconnect from the 5 GHz network when moving two walls away, while the 2.4 GHz signal remains stable due to its longer wavelength and better ability to diffract around obstacles.

Answer

The 5 GHz network is overloaded with users.

Answer

The laptop's Wi-Fi adapter is faulty.

Answer

The access point is configured to prioritize 2.4 GHz traffic.

Question 13

A technician is installing a new network drop in a warehouse where the cable must run near high-voltage machinery. The run is 60 meters. Which type of cable should be used to minimize interference?

Accepted Answer

STP Cat6a cable.. STP Cat6a cable includes a conductive shield that protects against electromagnetic interference (EMI) from nearby high-voltage machinery. The 60-meter run is well within Cat6a's 100-meter maximum segment length, making it the best choice for this environment.

Answer

UTP Cat6 cable.

Answer

Coaxial RG-6 cable.

Answer

Fiber optic cable.

Question 14

A technician is troubleshooting a wireless network where users experience intermittent drops during peak hours. The access point is an 802.11n model operating on 2.4 GHz. The technician suspects channel congestion. Which tool should the technician use to identify the least congested channel?

Accepted Answer

Wi-Fi analyzer. A Wi-Fi analyzer is the correct tool because it scans the 2.4 GHz band and displays channel utilization, signal strength, and overlapping channels. This allows the technician to identify which channel has the least interference and congestion, directly addressing the intermittent drops during peak hours.

Answer

Spectrum analyzer

Answer

Cable tester

Answer

Ping command

Question 15

A technician is called to a home where the customer reports that their cable internet works fine, but the TV service has pixelated channels. The technician suspects a signal issue. What is the most appropriate tool to measure the signal strength and quality on the coaxial line?

Accepted Answer

A cable tester (signal level meter). A cable tester (signal level meter) is the correct tool because it measures both signal strength (in dBmV) and signal quality (SNR or MER) on a coaxial line, which directly diagnoses pixelation caused by poor signal levels or noise. The technician needs to verify that the RF signal from the cable provider meets the required thresholds (typically -10 to +10 dBmV for downstream) to ensure clear TV reception.

Answer

A tone generator and probe

Answer

A multimeter

Answer

An optical time-domain reflectometer (OTDR)
