A user's Android phone connects to the office Wi-Fi network and shows 'Connected' with full signal strength, but the user cannot load any websites. Other devices on the same network can access the internet without issues. The technician checks the phone's network settings and sees an IP address of 192.168.1.115 and a gateway of 192.168.1.1. The phone can successfully ping the gateway. Which of the following should the technician check NEXT?

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

Accepted Answer

The phone's DNS server settings. The phone can ping the gateway (192.168.1.1), confirming Layer 3 connectivity and that the gateway is reachable. Since other devices on the same network can access the internet, the issue is isolated to the phone's DNS resolution. Incorrect or missing DNS server settings would prevent domain name resolution while allowing IP-level communication, which matches the symptom of being unable to load websites despite full connectivity.

Answer

The phone's mobile data is enabled

Answer

The Wi-Fi network's security type

Answer

The phone's MAC address filtering

Question 2

A technician installs a second monitor on a desktop PC. Both monitors are connected to the same discrete GPU. The first monitor works correctly, but the second monitor shows 'No Signal'. The technician verifies the second monitor and its cable are functional by testing them on the first monitor's port. The GPU has two HDMI ports. Which of the following is the MOST likely cause?

Accepted Answer

The second HDMI port on the GPU is faulty. Since the technician verified that the second monitor and its cable work on the first monitor's HDMI port, the issue is isolated to the second HDMI port on the GPU. The most likely cause is that the second HDMI port is faulty, as all other components have been proven functional. This aligns with the symptom of a single port failing while the GPU otherwise supports dual displays.

Answer

The GPU does not support dual monitors

Answer

The monitor's resolution is set higher than the GPU supports

Answer

The GPU lacks sufficient video memory to drive both displays

Question 3

A user reports that their desktop computer cannot access the internet, but it can access internal network resources and other computers on the local network. The technician runs ipconfig and sees the IP address is 169.254.15.22. Which of the following is the MOST likely cause of this issue?

Accepted Answer

The DHCP server is not responding. The IP address 169.254.15.22 is an Automatic Private IP Addressing (APIPA) address (169.254.0.0/16), which Windows assigns when a DHCP server is unreachable. Since the computer can still access local resources, the network stack is functional, but without a valid DHCP lease, it cannot obtain a routable IP, default gateway, or DNS server, thus losing internet access.

Answer

The DNS server is not responding

Answer

The default gateway is misconfigured

Answer

The network cable is unplugged

Question 4

A company plans to migrate a customer-facing web application to the cloud. The application must automatically handle sudden traffic spikes by adding virtual servers without any manual intervention. Which cloud computing characteristic is MOST essential for this requirement?

Accepted Answer

Rapid elasticity. Rapid elasticity is the cloud characteristic that enables automatic scaling of resources up or down in response to demand, often without manual intervention. For a web application that must handle sudden traffic spikes by adding virtual servers automatically, rapid elasticity is essential because it allows the cloud infrastructure to provision and de-provision compute resources dynamically, typically using auto-scaling groups or similar mechanisms.

Answer

Resource pooling

Answer

Measured service

Answer

On-demand self-service

Question 5

A technician replaced the screen assembly on a smartphone. After reassembly, the phone powers on and displays correctly, but the touch screen is unresponsive. Which of the following should the technician check FIRST?

Accepted Answer

Ensure the digitizer ribbon cable is properly seated. The digitizer ribbon cable connects the touch-sensitive layer of the screen to the motherboard. If it is loose or improperly seated after reassembly, the touch input cannot be registered even though the display (LCD/OLED) works fine. This is the most likely cause given the recent disassembly and should be checked first before any software or replacement steps.

Answer

Reboot the phone into safe mode

Answer

Update the touch screen drivers

Answer

Replace the screen assembly again

Question 6

A user reports that their smartphone's GPS cannot get a lock, and the compass app shows a wrong direction. The phone recently had its screen replaced by a third-party repair shop. Which of the following is the MOST likely cause of these issues?

Accepted Answer

The GPS antenna or magnetometer was disconnected or damaged during repair.. The GPS antenna and magnetometer (compass) are often integrated into the display assembly or flex cables near the top of the phone. A third-party screen replacement can easily disconnect or damage these components, causing both GPS lock failure and incorrect compass readings. The digitizer (touch layer) is unrelated to GPS or magnetometer functionality.

Answer

The digitizer is not properly seated.

Answer

The replacement screen's refresh rate is incompatible with the GPS chipset.

Answer

The phone's battery was not calibrated after the screen replacement.

Question 7

A technician is upgrading a desktop computer's memory from 16GB (2x8GB) to 32GB (2x16GB). The technician purchases two 16GB DDR4-3200 modules from the same manufacturer and installs them in the recommended dual-channel slots (A2, B2). The system boots normally and reports 32GB. However, after running a memory-intensive application, the system crashes with a "MEMORY_MANAGEMENT" error. A memory diagnostic tool reports multiple errors at address ranges. The technician checks the BIOS and sees the memory is running at 3200MHz. The CPU is an Intel Core i7-10700K, which officially supports DDR4-2933. What is the most likely cause of the errors?

Accepted Answer

The CPU's memory controller is not rated for DDR4-3200, causing instability when XMP is enabled.. The Intel Core i7-10700K officially supports DDR4-2933. Running the memory at 3200MHz via XMP overclocks the CPU's integrated memory controller (IMC) beyond its rated specification. This can cause instability under load, leading to MEMORY_MANAGEMENT errors and diagnostic failures, even though the modules are from the same manufacturer and installed correctly.

Answer

The RAM modules are not compatible with the motherboard.

Answer

The RAM is installed in the wrong slots for dual-channel operation.

Answer

The power supply unit is providing insufficient voltage to the RAM.

Question 8

A technician is troubleshooting a workstation that emits one long beep followed by two short beeps during POST. The monitor shows no display. The technician has tested the dedicated GPU in another system where it worked, and has reseated all power cables and RAM. Which of the following should the technician try NEXT?

Accepted Answer

C. Clear the CMOS. The one long beep followed by two short beeps during POST is a standard AMI BIOS code indicating a video adapter failure. Since the dedicated GPU was tested and works in another system, and RAM has been reseated, the issue is likely a corrupted or misconfigured BIOS/UEFI setting (e.g., incorrect video initialization order or a stuck memory hole). Clearing the CMOS resets these settings to factory defaults, which can resolve the POST error without replacing hardware.

Answer

A. Replace the motherboard

Answer

B. Replace the power supply

Answer

D. Test the RAM in another system

Question 9

A user reports that their smartphone's earpiece speaker is extremely quiet during phone calls. The loudspeaker and Bluetooth audio work perfectly. The technician has already increased the in-call volume to maximum. Which of the following components is MOST likely faulty?

Accepted Answer

The earpiece speaker. The earpiece speaker is the most likely faulty component because the issue is isolated to the internal speaker used for phone calls, while the loudspeaker and Bluetooth audio work perfectly. This indicates that the audio signal path to the earpiece is compromised, but the audio amplifier chip and other audio outputs are functioning. The technician has already maximized the in-call volume, ruling out a software or user-setting issue.

Answer

The audio amplifier chip

Answer

The charging port

Answer

The proximity sensor

Question 10

A user reports that their laptop's Wi-Fi connection drops frequently, especially when the laptop is running on battery power. The technician checks Device Manager and sees the following setting enabled for the wireless adapter: 'Allow the computer to turn off this device to save power'. Which of the following is the MOST likely solution?

Accepted Answer

Uncheck the power saving option for the adapter. The 'Allow the computer to turn off this device to save power' setting in Device Manager causes the wireless adapter to be powered down when the laptop switches to battery power to conserve energy. This power-down interrupts the Wi-Fi connection, leading to frequent drops. Unchecking this option prevents the OS from suspending the adapter, ensuring a stable connection regardless of power source.

Answer

Disable the wireless adapter in Device Manager

Answer

Update the wireless adapter driver

Answer

Change the power plan to High Performance

Question 12

A technician is setting up a small network. The modem from the ISP provides a single public IP address via DHCP. The technician needs to connect 10 computers to the internet using a single public IP. Which device should the technician install between the modem and the computers to accomplish this?

Accepted Answer

Router with NAT capabilities. The modem provides a single public IP address via DHCP, but 10 computers need internet access. A router with NAT (Network Address Translation) allows multiple devices to share that single public IP by translating their private IP addresses (e.g., 192.168.1.x) to the public IP for outbound traffic, and mapping return traffic back to the correct internal device. This is the standard solution for IPv4 address conservation in small networks.

Answer

Hub

Answer

Switch

Answer

Bridge

Question 14

A user reports that their Android smartphone's GPS is not working accurately. The technician has confirmed that Location settings are set to High accuracy mode. Which of the following is the BEST next step to resolve this issue?

Accepted Answer

Calibrate the compass. Calibrating the compass is the best next step because Android smartphones use a magnetometer (compass) to determine orientation, which is essential for accurate GPS positioning, especially when the device is moving. High accuracy mode uses GPS, Wi-Fi, and mobile networks, but if the compass is uncalibrated, the device cannot correctly interpret direction, leading to inaccurate location fixes. Calibration resolves this by re-establishing the magnetometer's reference to the Earth's magnetic field.

Answer

Replace the GPS antenna

Answer

Update the PRL

Answer

Reset the network settings
