Question 2

A user wants to connect their laptop to a 4K TV for a movie marathon. They have a USB-C port on the laptop but the TV only has HDMI. Which accessory is required?

Accepted Answer

A USB-C to HDMI adapter.. USB-C supports DisplayPort Alternate Mode, which allows video signals to be transmitted over the USB-C connector. A USB-C to HDMI adapter converts the DisplayPort signal from the laptop into an HDMI signal compatible with the TV, enabling 4K video output. This is the standard solution for connecting a USB-C laptop to an HDMI-only display.

Answer

A USB-C to DisplayPort adapter.

Answer

A USB-C to VGA adapter.

Answer

A USB-C to Ethernet adapter.

Question 3

A company deploys a new 802.11ax (Wi-Fi 6) access point to support high-density environments. Some older laptops with 802.11ac adapters cannot connect, while newer Wi-Fi 6 laptops work fine. The SSID is broadcast and security is set to WPA2. What is the MOST likely cause?

Accepted Answer

The access point is set to 802.11ax-only mode.. If the access point is set to 802.11ax-only mode, older 802.11ac adapters, which are not 802.11ax compliant, will be unable to connect. Newer Wi-Fi 6 (802.11ax) laptops, however, will connect successfully. This mode setting directly explains why only the newer standard devices can connect while older ones cannot, without contradicting the stated WPA2 security.

Answer

The laptops have outdated firmware that does not support OFDMA.

Answer

The access point is configured to use WPA3 only.

Answer

The 5 GHz radio is disabled on the access point.

Question 4

A customer reports that their laptop connects to the office Wi-Fi but cannot access the internet. Other devices on the same network work fine. What is the most likely cause of this issue?

Accepted Answer

The laptop's default gateway address is incorrect. The laptop can connect to the Wi-Fi network but cannot access the internet, while other devices work fine. This points to a client-side configuration issue. The default gateway is the router that forwards traffic from the local subnet to external networks; if the laptop's default gateway address is incorrect, its packets cannot leave the local subnet, breaking internet access while local connectivity remains.

Answer

The laptop's DNS server address is set to a public DNS like 8.8.8.8

Answer

The laptop's IP address is set to a static address in the same subnet as the router

Answer

The office Wi-Fi network is using a different SSID than expected

Question 5

A user reports that their iPad's Safari browser crashes immediately upon opening, but other apps work fine. They have already restarted the device. What should the technician do next?

Accepted Answer

Clear Safari's history and website data in Settings.. Clearing Safari's history and website data removes corrupted cached files, cookies, or local storage data that can cause the browser to crash on launch. Since other apps work fine, the issue is isolated to Safari's stored data, not the entire system. This is the recommended first troubleshooting step for a single-app crash after a restart.

Answer

Perform a factory reset on the iPad.

Answer

Update iOS to the latest version.

Answer

Disable all Safari extensions.

Question 6

A company deploys several tablets for field technicians that need to connect to a private LTE network via a SIM card. One tablet connects to the network but has very slow data speeds. Other tablets in the same area work fine. What is the most likely cause?

Accepted Answer

The tablet is using the wrong APN configuration.. The most likely cause is an incorrect APN configuration. The APN (Access Point Name) defines the gateway between the LTE network and the internet, including required authentication and IP settings. If the APN is wrong, the tablet may still attach to the LTE network but will experience severely degraded data throughput because the packet data protocol (PDP) context cannot establish a proper data session.

Answer

The tablet's Wi-Fi is interfering with the LTE signal.

Answer

The tablet's SIM card is not fully inserted.

Answer

The tablet's battery saver mode is enabled.

Question 7

A customer reports that their wireless printer stops responding when the microwave is in use. The printer is connected via Wi-Fi to a dual-band router. Which troubleshooting step should the technician take first to resolve this issue?

Accepted Answer

Connect the printer to the 5 GHz network. The microwave oven operates in the 2.4 GHz ISM band, generating broadband interference that disrupts Wi-Fi communication on that frequency. Connecting the printer to the 5 GHz network avoids this interference entirely because the 5 GHz band is not affected by microwave emissions, providing a clean channel for the printer.

Answer

Replace the printer with a wired model

Answer

Change the router’s 2.4 GHz channel

Answer

Update the printer firmware

Question 8

A technician is setting up a new Android tablet for a warehouse worker who uses a barcode scanner app that requires constant Wi-Fi. The warehouse has multiple access points with the same SSID. The tablet frequently disconnects and reconnects as the worker moves around. What should the technician configure to improve connectivity?

Accepted Answer

Enable the 'Wi-Fi roaming' or 'aggressive handover' setting in the tablet's advanced Wi-Fi options.. Enabling 'Wi-Fi roaming' or 'aggressive handover' configures the tablet to actively scan for stronger access points and initiate a faster re-association when signal strength degrades. This setting reduces the disconnection/reconnection cycles common in multi-AP environments with the same SSID by triggering a proactive handoff before the current link is lost.

Answer

Set the tablet to use a static IP address.

Answer

Disable the tablet's Bluetooth radio.

Answer

Configure the tablet to prefer the 2.4 GHz band over 5 GHz.

Question 9

A technician is upgrading a workstation from DDR3 to DDR4 memory. The motherboard currently has two DDR3 DIMM slots occupied. What must the technician verify before installing the new memory?

Accepted Answer

The motherboard has DDR4 DIMM slots. DDR3 and DDR4 have different notch positions and voltage requirements, so they are not interchangeable. The motherboard must physically support DDR4, which means it must have DDR4 DIMM slots. The CPU socket type and chipset are secondary; the key factor is the motherboard's memory generation support.

Answer

The CPU supports DDR4 memory

Answer

The power supply has a 4-pin connector for memory

Answer

The chipset supports dual-channel configuration

Question 10

A user reports that their cloud-based file synchronization service stopped updating files after a recent OS update. The technician verifies the service is running and the internet connection is active. What should the technician check next?

Accepted Answer

Check the sync client's authentication status. Cloud file sync issues often stem from authentication problems, such as expired credentials or session tokens. Since the service is running and connectivity is fine, the most likely cause is that the user's login token expired and needs re-authentication. Checking the sync logs would reveal the authentication failure.

Answer

Reinstall the sync client application

Answer

Disable the firewall temporarily

Answer

Increase the storage quota on the cloud account

Question 11

After replacing a motherboard, a technician installs Windows but the system will not boot from the SSD. The drive is detected in UEFI. The technician recalls the previous motherboard used Legacy BIOS. What is the most likely issue?

Accepted Answer

The UEFI is set to UEFI mode but the drive uses MBR. The most likely issue is a mismatch between the UEFI firmware mode and the partition scheme on the SSD. If the previous motherboard used Legacy BIOS, the drive was likely initialized with an MBR partition table, which requires Legacy/CSM boot mode. A UEFI system expects a GPT partition table with an EFI System Partition, so it cannot boot from an MBR drive unless CSM is enabled.

Answer

The SSD is not getting power

Answer

Secure Boot is blocking the Windows bootloader

Answer

The CMOS battery is dead

Question 12

During a security audit, a technician discovers that an internal web server is responding on port 8080 instead of the standard HTTP port. What is the most likely reason for this configuration?

Accepted Answer

The server is configured as a web proxy or alternate HTTP server.. Port 8080 is commonly used as an alternate HTTP port, often for web proxy servers or secondary HTTP servers. This allows administrators to run a separate HTTP service without conflicting with the standard port 80, which is frequently used for caching proxies or development environments.

Answer

The server is running HTTPS on a non-standard port.

Answer

The server is running an FTP service.

Answer

The server is using a custom application protocol.

Question 13

A user complains that their laptop's touchpad cursor jumps erratically while typing. They have cleaned the touchpad surface, but the issue persists. Which configuration change should you try first?

Accepted Answer

Enable the 'Ignore accidental touches' or 'PalmCheck' feature in the touchpad settings.. Erratic cursor movement while typing is a classic sign of palm rejection not working correctly. The most common fix is to enable the 'disable touchpad while typing' feature in the touchpad settings. This prevents accidental input from the user's palms during typing.

Answer

Increase the touchpad sensitivity in the operating system settings.

Answer

Update the touchpad driver from the manufacturer's website.

Answer

Disable the touchpad entirely and use an external mouse.

Question 14

A technician is installing a power supply in a new build. The case has a bottom-mounted PSU bay with a dust filter. The technician notices that the PSU fan faces downward. Is this correct?

Accepted Answer

Yes, the fan should face downward to draw cool air from outside the case.. In a bottom-mounted PSU configuration, the fan should face downward to draw cool air from outside the case through the dust filter. This improves cooling efficiency and reduces dust buildup inside the case.

Answer

No, the fan should face upward to exhaust hot air from inside the case.

Answer

No, the PSU should be mounted fan-up to prevent dust from entering.

Answer

The orientation does not matter as long as the PSU is securely mounted.

Question 15

A small office uses a wireless printer that supports Wi-Fi Direct. Several employees want to print from their smartphones without connecting to the company's wireless network. What is the simplest way to achieve this?

Accepted Answer

Use the printer's Wi-Fi Direct feature to connect each phone directly.. Wi-Fi Direct allows devices to connect peer-to-peer without a traditional wireless access point. Since the printer supports Wi-Fi Direct, each smartphone can connect directly to the printer's own Wi-Fi Direct network, enabling printing without joining the company's wireless network. This is the simplest method because it requires no additional hardware or network configuration.

Answer

Connect the printer to the office router via Ethernet.

Answer

Enable the printer's Bluetooth and pair each phone.

Answer

Install a USB hub and connect all phones to the printer.
