Question 1

A user's Android tablet was dropped and the glass digitizer cracked, but the LCD display still shows images correctly. The user reports that touch input is unresponsive in several areas of the screen. Which of the following replacement procedures is MOST appropriate?

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

Accepted Answer

Replace the entire screen assembly (LCD and digitizer together). When the glass digitizer is cracked but the LCD display still functions, the digitizer (touch panel) is the damaged component. However, in most modern Android tablets, the digitizer is fused to the LCD as a single screen assembly, making it impractical or impossible to replace only the digitizer without damaging the LCD. Therefore, replacing the entire screen assembly (LCD and digitizer together) is the most appropriate procedure to restore full touch functionality.

Answer

Replace only the LCD display

Answer

Replace only the digitizer (touch panel)

Answer

Perform a touchscreen recalibration

Question 2

A user reports that their desktop computer loses network connectivity every few minutes, especially when the nearby overhead fluorescent lights are turned on. The technician observes that the link light on the NIC occasionally turns off during these events. The Ethernet cable is a Cat5e unshielded twisted pair (UTP) cable routed through the ceiling near the light fixtures. Which of the following is the MOST likely cause of the intermittent connectivity?

Accepted Answer

Electromagnetic interference (EMI) from the fluorescent lights is affecting the unshielded cable. Unshielded twisted pair (UTP) cables lack shielding against electromagnetic interference (EMI). Fluorescent lights, especially older magnetic-ballast fixtures, generate strong EMI that can induce noise in nearby UTP cables, corrupting data signals and causing the NIC's link light to drop. This explains the correlation between the lights turning on and the loss of connectivity.

Answer

The network interface card (NIC) is faulty and needs replacement

Answer

The switch port is configured with an incorrect VLAN assignment

Answer

The DHCP server has exhausted its IP address scope

Question 3

A user reports that their smartphone will charge wirelessly on a charging pad but will not charge when connected to a USB-C cable. The USB-C cable and charger work normally when tested on another phone. The technician has already performed a forced restart and cleaned the charging port with compressed air. Which component should the technician replace FIRST?

Accepted Answer

Charging port. Charging port. Since the USB-C cable and charger work on another phone, the cable and charger are verified functional. The phone charges wirelessly, which bypasses the charging port entirely, confirming the battery and charging IC are operational. The technician has already cleaned the port and performed a forced restart, so the most likely remaining hardware fault is a damaged or worn charging port that cannot establish a proper electrical connection with the USB-C cable.

Answer

Battery

Answer

Charging IC

Answer

USB-C cable

Question 4

A company uses a public cloud IaaS provider to host a web application. The application experiences occasional spikes in traffic. The cloud provider offers a service that automatically adds or removes virtual machine instances based on CPU utilization. This is an example of which cloud characteristic?

Accepted Answer

Rapid elasticity. The scenario describes a cloud service that automatically scales virtual machine instances up or down in response to CPU utilization spikes. This ability to provision and release resources quickly and automatically to match demand is the defining characteristic of rapid elasticity, which allows resources to appear unlimited to the consumer and scale elastically based on workload.

Answer

Measured service

Answer

On-demand self-service

Answer

Resource pooling

Question 5

A multinational company is migrating its customer data to a cloud provider. Legal requirements mandate that all customer data must be stored on servers physically located within the country of origin. Which cloud characteristic must the company verify before selecting a provider?

Accepted Answer

Regional availability. The company must ensure the cloud provider offers regional availability, meaning the provider has data centers physically located within the specific country required by law. This characteristic allows customers to select the geographic region where their data will be stored, directly addressing the legal mandate for data residency. Without regional availability, the provider might store data in any global location, violating compliance requirements.

Answer

Elasticity

Answer

High availability

Answer

Shared responsibility model

Question 6

A user reports that their desktop computer shuts down unexpectedly when running video editing software. The technician has already verified that CPU and GPU temperatures are within normal limits under load, the power supply unit is 650W and should be adequate, and all fans are spinning. The system has been stable for two years prior to this issue. Which of the following should the technician check NEXT as the MOST likely cause?

Accepted Answer

Inspect the motherboard for bulging or leaking capacitors. Bulging or leaking capacitors on the motherboard can cause intermittent power delivery issues, leading to unexpected shutdowns under load even when CPU/GPU temperatures and PSU wattage appear adequate. Capacitor degradation is a common failure mode in systems that have been stable for years, as electrolytic capacitors dry out or fail over time, especially under sustained thermal stress from video editing workloads.

Answer

Update the motherboard BIOS to the latest version

Answer

Run a memory diagnostic (e.g., MemTest86) to check for RAM errors

Answer

Replace the CPU with a known-good processor

Question 7

A user's iPhone will not charge even though the screen is cracked but still displays properly and responds to touch. The technician has cleaned the Lightning port and verified the charging cable and power adapter work with another device. Which component most likely needs replacement?

Accepted Answer

Replace the charging port flex cable. The iPhone charges through the Lightning port, which is connected to the logic board via the charging port flex cable. Since the screen is cracked but still displays and responds to touch, the LCD and digitizer are functional. The technician has already ruled out the cable and power adapter, so the most likely failure is the charging port flex cable, which can be damaged by debris, corrosion, or physical stress from the cracked screen.

Answer

Replace the LCD assembly

Answer

Replace the digitizer

Answer

Replace the battery

Question 8

A cloud service provider uses a Type 1 hypervisor to host multiple tenant virtual machines on a single physical server. This allows the provider to serve many customers from the same infrastructure while maintaining isolation. Which essential characteristic of cloud computing does this best represent?

Accepted Answer

Resource pooling. Resource pooling is the correct answer because a Type 1 hypervisor (bare-metal hypervisor) abstracts the physical server's CPU, memory, and storage into a shared resource pool that can be dynamically allocated to multiple tenant VMs. This allows the provider to serve many customers from the same physical infrastructure while maintaining logical isolation, which is the defining characteristic of resource pooling in cloud computing.

Answer

Rapid elasticity

Answer

Measured service

Answer

Broad network access

Question 9

A technician is assembling a desktop computer using an Intel LGA1151 socket motherboard. The CPU has been installed correctly with thermal paste and a heatsink. When the power button is pressed, the system powers on for about three seconds, then shuts off, and then repeatedly attempts to restart. The CPU cooler fan spins normally during that time. Which of the following is the MOST likely cause?

Accepted Answer

The 4+4 pin EPS12V power connector is not plugged into the motherboard. The 4+4 pin EPS12V connector provides dedicated power to the CPU. Without it, the CPU cannot initialize, causing the motherboard's fail-safe to power off after a few seconds and then repeatedly attempt to restart. The cooler fan spinning normally indicates the system is receiving basic power, but the CPU lacks the necessary voltage to complete POST.

Answer

The RAM modules are not fully seated in their slots

Answer

The CMOS battery is depleted

Answer

The power supply is not rated for the required wattage

Question 10

A company wants to migrate its on-premises infrastructure to the cloud. The security team requires that the company retains full control over network configuration, firewall rules, and security policies, but they do not want to manage physical servers, storage, or the underlying hypervisor. Which cloud service model BEST meets these requirements?

Accepted Answer

Infrastructure as a Service (IaaS). Infrastructure as a Service (IaaS) provides virtualized computing resources over the internet, allowing the company to manage and control the network configuration, firewall rules, and security policies while the cloud provider handles the physical servers, storage, and hypervisor. This model gives the customer full control over the operating system, storage, and deployed applications, meeting the requirement of not managing the underlying physical infrastructure.

Answer

Software as a Service (SaaS)

Answer

Platform as a Service (PaaS)

Answer

Database as a Service (DBaaS)

Question 11

A technician is troubleshooting a desktop PC that emits three short beeps and then repeats after the power button is pressed. The monitor remains black and the system does not display any video. The motherboard uses an AMI BIOS. Which of the following is the MOST likely cause?

Accepted Answer

The RAM is not properly seated or is faulty. AMI BIOS uses three short beeps to indicate a base memory (first 64KB) read/write error, which almost always points to a RAM issue. Since the system fails POST before any video output, the RAM being improperly seated or faulty is the most likely cause.

Answer

The CPU has failed

Answer

The graphics card is not seated correctly

Answer

The CPU cooler is loose and causing overheating

Question 12

A technician replaced the cracked screen on an iPhone 11. After reassembling the device, the phone powers on and responds to touch, but the display remains black. The technician hears the camera shutter sound when tapping the camera icon. Which of the following is the MOST likely cause?

Accepted Answer

The display cable is not connected properly. The iPhone 11 uses a single display assembly cable that carries both the LCD data and the digitizer (touch) signals. If the display cable is not fully seated or is damaged, the phone may still power on and register touch input (because the digitizer portion of the cable has partial contact), but the LCD backlight or data lines may be interrupted, resulting in a black screen. The camera shutter sound confirms the device is operational and the logic board is functioning, isolating the issue to the display connection.

Answer

The battery connector is loose

Answer

The front camera flex cable is damaged

Answer

The motherboard was damaged during the repair

Question 13

A user reports that their smartphone charges intermittently. The technician observes that the USB-C cable fits very loosely into the charging port and often falls out. Which component is MOST likely causing this issue?

Accepted Answer

The charging port or connector is damaged or worn.. The USB-C cable fitting loosely and falling out of the charging port is a classic sign of physical wear or damage to the port or connector. Over time, the internal retention clips or solder joints inside the port can degrade, preventing a secure mechanical and electrical connection. This intermittent physical contact directly causes the intermittent charging behavior, not a software or battery issue.

Answer

The battery is no longer able to hold a charge.

Answer

The operating system has a bug affecting charging.

Answer

The firmware controlling the charging circuit is corrupted.

Question 14

A small business uses a cloud-based customer relationship management (CRM) system that is accessed entirely through a web browser. The business does not manage the underlying operating system, middleware, or hardware. Which cloud computing service model does this scenario BEST describe?

Accepted Answer

Software as a Service (SaaS). This scenario describes Software as a Service (SaaS) because the business consumes a fully functional CRM application delivered over the web, with no control over the underlying operating system, middleware, or hardware. The provider manages the entire stack, and the customer only accesses the software via a browser, which is the defining characteristic of SaaS.

Answer
