The ink cartridge nozzles

Answer

The paper type setting

Answer

The printer driver version

Question 3

A customer reports that their desktop PC is running very slowly, especially when opening multiple applications. The system has 8 GB of RAM and a 1 TB HDD. You check Task Manager and see that the CPU is consistently at 100% usage even with only a few apps open. Which CPU characteristic is most likely causing this bottleneck?

Accepted Answer

Clock speed. This scenario tests understanding of how CPU clock speed affects multitasking performance. A low clock speed means the processor cannot execute instructions quickly enough, leading to high usage and sluggishness. Upgrading to a CPU with a higher clock speed would directly address the bottleneck.

Answer

Number of cores

Answer

Cache size

Answer

Thermal design power (TDP)

Question 4

A user reports that their new Bluetooth headset pairs with their smartphone but no audio is heard during calls. The headset works fine with another phone. What is the most likely cause?

Accepted Answer

The phone is not using the correct Bluetooth profile for calls.. The most likely cause is that the phone is not using the correct Bluetooth profile for calls. Bluetooth headsets require the Hands-Free Profile (HFP) or Headset Profile (HSP) for bidirectional audio during calls. If the phone defaults to the Advanced Audio Distribution Profile (A2DP) for media streaming instead, audio will not route through the headset for calls. Since the headset works with another phone, the issue is specific to the phone's profile selection or configuration.

Answer

The headset battery is low.

Answer

The headset is out of Bluetooth range.

Answer

The phone's Bluetooth radio is faulty.

Question 5

A technician is configuring a new wireless network for a small business. The owner wants to ensure that only company-issued laptops can connect, and that data is encrypted. The laptops support WPA2-Enterprise. Which authentication method should be used?

Accepted Answer

802.1X with a RADIUS server. WPA2-Enterprise uses 802.1X authentication, which requires a RADIUS server to validate individual user or device credentials. This allows the business to enforce that only company-issued laptops (which have the correct certificates or credentials) can connect, while also providing strong per-session encryption via dynamic WPA2 keys.

Answer

WPA2-PSK with a strong passphrase

Answer

WPA3-SAE (Simultaneous Authentication of Equals)

Answer

MAC address filtering

Question 6

A user wants to mirror their Android smartphone's screen to a smart TV that does not support Miracast. The TV has HDMI and USB ports. Which device should the technician recommend?

Accepted Answer

A Chromecast device. A Chromecast device connects to the TV via HDMI and uses Wi-Fi Direct (not Miracast) to receive a screen mirror from an Android smartphone. Since the TV lacks Miracast support but has an HDMI port, Chromecast provides the necessary hardware and protocol (Google Cast) to enable wireless display mirroring.

Answer

A USB-C to HDMI cable

Answer

A Bluetooth transmitter

Answer

An NFC tag

Question 7

A company deploys a new 802.11ac access point in a warehouse. After installation, workers report that their handheld scanners frequently disconnect when moving between aisles. The AP is mounted on a high ceiling. Which configuration change would most likely improve connectivity?

Accepted Answer

Change the AP to use only 2.4 GHz band.. The 5 GHz band used by 802.11ac has poorer penetration and range through obstacles like warehouse shelving and inventory. By switching to the 2.4 GHz band, signals diffract better around aisles and through racks, reducing disconnections for mobile scanners moving between aisles.

Answer

Increase the AP's channel width to 80 MHz.

Answer

Enable WPA3 encryption on the network.

Answer

Reduce the AP's transmit power to avoid interference.

Question 8

A user brings in a smartphone with a cracked screen that is still responsive to touch. The device is an older model, and the user wants the screen replaced rather than buying a new phone. After powering off the device and removing the SIM and SD cards, what is the next step in the screen replacement process?

Accepted Answer

Apply heat to the edges of the screen to soften the adhesive.. Applying heat to the edges of the screen softens the adhesive that secures the display to the frame, which is a critical step before any prying action. On older smartphone models, the screen is typically bonded with a strong adhesive that can crack the glass further or damage the LCD if pried without softening. This step reduces the risk of breaking the digitizer or LCD during removal.

Answer

Use a spudger to pry the screen off starting from the bottom.

Answer

Remove the battery using a plastic pry tool.

Answer

Insert a guitar pick under the screen to separate it from the frame.

Question 9

You are deploying a new VoIP phone and need to ensure the Ethernet cable from the wall jack to the phone is properly terminated and has no shorts. The cable appears to be wired correctly but you want to confirm. Which tool should you use?

Accepted Answer

Cable tester. A cable tester verifies continuity, pin-to-pin wiring, and detects shorts or opens in an Ethernet cable. Since the question states the cable appears correctly wired but you need to confirm proper termination and absence of shorts, the cable tester is the correct tool for this passive copper cable validation.

Answer

Toner probe

Answer

Loopback plug

Answer

Multimeter

Question 10

A user reports that after installing a new app on their Android phone, the device has become noticeably slower and the battery drains faster. What is the most likely cause?

Accepted Answer

The app is running background services that consume resources.. The most common cause of performance degradation and increased battery drain after installing a new app is that the app runs background services, such as sync adapters, location listeners, or push notification keep-alives. These services consume CPU cycles, memory, and network activity even when the app is not in the foreground, leading to slower device responsiveness and faster battery depletion.

Answer

The app is a known malware that steals personal data.

Answer

The phone's storage is full from the app installation.

Answer

The app requires a newer version of Android.

Question 11

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 12

During a site survey for a new branch office, you measure signal strength in the conference room and find it is -85 dBm. The client devices require at least -67 dBm for reliable video conferencing. Which action is most appropriate?

Accepted Answer

Install an additional access point in the conference room ceiling.. The measured signal strength of -85 dBm is well below the -67 dBm threshold required for reliable video conferencing. Installing an additional access point in the conference room ceiling is the most appropriate action because it reduces the distance and obstacles between the client devices and the AP, directly improving the received signal strength (RSSI) to meet the application's requirements. Simply increasing transmit power on the existing AP may cause co-channel interference and may not overcome path loss from distance or obstructions, while changing channels or replacing client antennas does not address the fundamental lack of signal coverage.

Answer

Increase the transmit power of the existing access point to maximum.

Answer

Replace the client devices with ones that have better antennas.

Answer

Change the channel on the existing AP to a less congested one.

Question 13

A company is upgrading its network to support 10 Gbps speeds for a server farm. The existing cabling is Cat6a, and the switches are Gigabit. The IT manager wants to minimize cost while achieving 10 Gbps. Which hardware change is required?

Accepted Answer

Install 10 Gbps switches and use the existing Cat6a cabling.. Cat6a cabling is rated to support 10 Gbps Ethernet up to 100 meters, so no cable replacement is needed. The bottleneck is the existing Gigabit switches, which must be upgraded to 10 Gbps switches to achieve the desired speed. This is the most cost-effective approach because it avoids the expense of new cabling.

Answer

Replace the Cat6a cabling with Cat7 cabling.

Answer

Replace the switches with Gigabit models that have SFP+ ports for fiber.

Answer

Add a repeater to boost the signal on the existing Cat6a cabling.

Question 14

A company has two branch offices in different cities. They need to connect their LANs so employees can access resources at both locations securely over the internet. Which network type should be used?

Accepted Answer

Wide Area Network (WAN). A Wide Area Network (WAN) is the correct choice because it connects geographically separated LANs across a large distance, such as between two cities, using public or private infrastructure like the internet. WAN technologies, such as MPLS, leased lines, or IPsec VPNs, provide secure, encrypted tunnels over the internet to ensure data confidentiality and integrity between the branch offices.

Answer

Local Area Network (LAN)

Answer

Metropolitan Area Network (MAN)

Answer

Personal Area Network (PAN)

Question 15

A technician is setting up a mobile point-of-sale system using a tablet and a portable receipt printer. The printer supports both Bluetooth and NFC. Which connection method should the technician use for reliable, low-latency printing?

Accepted Answer

Bluetooth. Bluetooth is the correct choice because it provides a reliable, low-latency wireless connection specifically designed for peripheral devices like printers. Unlike NFC, which is optimized for very short-range (under 4 cm) tap-to-pair operations and not sustained data streaming, Bluetooth maintains a stable link over distances up to 10 meters and supports the Serial Port Profile (SPP) or Bluetooth Basic Rate/Enhanced Data Rate (BR/EDR) for consistent print job throughput.

Answer

NFC

Answer

Infrared

Answer

Wi-Fi Direct
