The USB port on the phone appears clean and free of debris. Which of the following components is MOST likely faulty and should be replaced?

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

Accepted Answer

Charging port flex cable. The charging port flex cable is the most likely faulty component because the technician has already ruled out external factors (cable and wall adapter) and the USB port appears clean. The flex cable connects the USB port to the phone's motherboard, and internal damage or wear to this cable can interrupt power delivery even when the port itself looks fine. Replacing the flex cable is a common repair for charging issues that persist after basic troubleshooting.

Question 2

A user's iPhone 13 will not power on after being plugged in overnight with a Lightning cable. The technician tries a different cable and power adapter with no success. The technician inspects the Lightning port and removes a small amount of debris, but the phone remains unresponsive. When the technician places the phone on a Qi wireless charger, the screen briefly displays a battery icon and then goes black. Which of the following is the MOST likely cause of the issue?

Accepted Answer

The Lightning port assembly is faulty. The phone responds to Qi wireless charging (brief battery icon) but not to wired charging, which isolates the issue to the Lightning port or its internal connection. Since the technician already tried different cables, adapters, and removed visible debris, the most likely cause is a faulty Lightning port assembly—such as a damaged connector, broken solder joints, or internal corrosion—that prevents power delivery via the Lightning path while leaving wireless charging functional.

Answer

The battery has failed and needs replacement

Answer

The power button is stuck in the pressed position

Answer

The logic board has a short circuit

Question 3

A technician is building a new desktop computer. After installing the motherboard, CPU, RAM, and graphics card, the technician connects the 24-pin main power cable and all other necessary cables. When the power button is pressed, the fans spin for about one second and then stop. The motherboard's power LED does not illuminate. The technician uses a multimeter and confirms the power supply outputs 12V, 5V, and 3.3V on the appropriate pins of the 24-pin connector. Which of the following is the MOST likely cause of the issue?

Accepted Answer

The 4/8-pin CPU power connector is not connected.. The 4/8-pin CPU power connector provides dedicated 12V power to the CPU voltage regulator module (VRM). Without it, the CPU receives no power, so the system immediately shuts down after a brief fan spin (due to residual charge or a momentary power-on signal). The multimeter confirms the main 24-pin ATX connector is delivering correct voltages, ruling out a PSU failure.

Answer

The front panel power switch header is connected to the wrong pins.

Answer

The RAM modules are not fully seated in the slots.

Answer

The CMOS battery is depleted and needs replacement.

Question 4

A company uses a public cloud IaaS provider. They have deployed a web application across multiple virtual machines in an auto-scaling group. The application requires temporary storage for processing user uploads. The data is only needed while the VM is running and must be deleted when the VM is terminated. The storage must be attached to a single VM and should provide low-latency access. Which cloud storage type should the technician configure?

Accepted Answer

Ephemeral storage (instance store). Ephemeral storage (instance store) is correct because it provides temporary, block-level storage directly attached to a single VM, offering low-latency access. The data is tied to the VM's lifecycle and is automatically deleted when the VM is terminated, matching the requirement for temporary processing of user uploads that must not persist after the VM stops.

Answer

Object storage

Answer

File storage

Answer

Persistent block storage

Question 5

A company hosts a critical web application on a public cloud provider. The architecture uses virtual server instances in two geographically separate data centers (regions). A global load balancer monitors the health of each region and distributes incoming user traffic. If an entire region becomes unavailable due to a natural disaster, the load balancer automatically redirects all traffic to the remaining healthy region. This design is intended to meet a specific business requirement. Which cloud characteristic does this architecture BEST demonstrate?

Accepted Answer

High availability. This architecture demonstrates high availability because it uses redundant virtual server instances across two geographically separate regions with a global load balancer that performs automatic failover. When an entire region becomes unavailable due to a disaster, the load balancer detects the health check failure (e.g., HTTP 503 or TCP timeout) and redirects all traffic to the remaining healthy region, ensuring the application remains accessible. This design minimizes downtime and meets the business requirement for continuous operation despite regional outages.

Question 6

A user reports that during phone calls on their Android smartphone, the caller's voice sounds very low and muffled through the earpiece speaker. The technician has cleaned the speaker grille with a soft brush and the issue persists. The phone otherwise functions normally with media sounds playing at adequate volume. Which of the following should the technician check NEXT?

Accepted Answer

Check the call volume setting and adjust it during a test call. The symptom—low and muffled voice specifically during calls, with normal media volume—points to a call volume setting being too low, not a hardware failure. The technician should first adjust the in-call volume during a test call, as this is a separate software-controlled gain stage from media volume. Since cleaning the grille didn't resolve it, the next logical step is to verify and adjust the call volume slider, which is a common user-misconfiguration issue.

Answer

Replace the earpiece speaker module

Answer

Disable Bluetooth to rule out audio redirection

Answer

Reset the audio codec settings in developer options

Question 7

An employee connects their laptop to the company network via Ethernet. They can access the internet but cannot connect to internal servers using their hostnames (e.g., \fileserver). They can ping internal server IPs. The network uses an internal DNS server at 192.168.1.5. The technician checks the laptop's network adapter settings and sees that the DNS server is manually set to 8.8.8.8. Which of the following is the MOST likely cause of the issue?

Accepted Answer

The laptop is configured to use a public DNS server instead of the internal DNS server.. The laptop can access the internet and ping internal servers by IP, confirming that basic IP connectivity and routing are functional. However, it cannot resolve internal hostnames because its DNS server is manually set to 8.8.8.8 (a public Google DNS server), which does not have records for the company's internal domain. The internal DNS server at 192.168.1.5 is required to resolve names like \fileserver, so using an external DNS server breaks internal name resolution.

Answer

The laptop's IPv4 address is outside the company's subnet.

Answer

The DNS resolver cache on the laptop is corrupted.

Answer

The internal DNS server is not responding to queries from different subnets.

Question 8

A technician is building a high-performance workstation for data analysis. The user requires error-correcting code (ECC) memory for data integrity. The technician selects an Intel Xeon processor and a motherboard with a chipset that supports registered memory. Which type of RAM should the technician install?

Accepted Answer

Registered ECC DDR4 (RDIMM). The Intel Xeon processor and motherboard chipset support registered memory, which uses a register to buffer the address and control signals, reducing electrical load on the memory controller. Registered ECC DDR4 (RDIMM) is the correct type because it combines error-correcting code (ECC) for data integrity with the registered buffer required by the platform, ensuring stability and compatibility in high-performance workstation builds.

Answer

Unbuffered non-ECC DDR4

Answer

Unbuffered ECC DDR4 (UDIMM)

Answer

Load-reduced ECC DDR4 (LRDIMM)

Question 9

A technician is upgrading a desktop computer with a new CPU and motherboard. After installation, the computer powers on but the monitor displays 'No Signal'. The technician verifies the monitor works, and the GPU fans spin. The motherboard has no onboard video. Which of the following should the technician do FIRST?

Accepted Answer

Check the CPU power connector. The CPU power connector (typically a 4+4 pin EPS12V connector) supplies dedicated power to the CPU. If it is not connected or is loose, the CPU will not initialize, causing the system to power on (fans spin, lights come on) but fail to POST, resulting in a 'No Signal' display. Since the GPU fans spin and the monitor works, the issue is likely a lack of CPU power, making checking this connector the first logical step.

Answer

Reseat the GPU

Answer

Clear the CMOS

Answer

Update the BIOS

Question 10

A cloud administrator needs to increase the amount of RAM allocated to a running virtual machine (VM) from 4GB to 8GB to handle a temporary workload spike. The administrator logs into the cloud management console, selects the VM, and changes the instance type to one with 8GB of RAM. The change takes effect immediately without requiring a reboot. Which cloud computing characteristic does this scenario BEST illustrate?

Accepted Answer

Rapid elasticity. Rapid elasticity is the cloud characteristic that allows resources to be scaled up or down quickly and automatically, often without requiring a reboot. In this scenario, the administrator changes the instance type to one with 8GB of RAM, and the change takes effect immediately, demonstrating the rapid provisioning and de-provisioning of resources to meet workload demands.

Answer

Measured service

Answer

Resource pooling

Answer

On-demand self-service

Question 11

A technician upgrades a desktop computer by installing a new M.2 NVMe SSD. The computer previously booted from a SATA SSD connected to port 0. After the installation, the computer fails to boot and enters the BIOS setup utility. The BIOS detects both the SATA SSD and the M.2 NVMe drive. Which of the following should the technician do FIRST to resolve the boot issue?

Accepted Answer

Change the boot order in the BIOS to prioritize the SATA SSD. The correct first step is to change the boot order in the BIOS to prioritize the SATA SSD. Installing a new M.2 NVMe SSD often causes the BIOS to reset the boot order or default to the newly detected drive, especially if the M.2 slot shares bandwidth with SATA ports. Since the BIOS detects both drives, the boot failure is due to the system attempting to boot from the empty M.2 drive rather than the existing SATA SSD with the OS.

Answer

Disable the M.2 slot in the BIOS

Answer

Reinstall the operating system on the M.2 NVMe drive

Answer

Remove the SATA SSD from the system

Question 12

A company hosts its customer relationship management (CRM) application on a single virtual machine (VM) in a public cloud. The VM is configured with a static private IP address that is used by a third-party service to send data to the application. During a scheduled hardware maintenance event, the cloud provider automatically migrates the VM to a different physical host. After the migration, the CRM application can no longer receive data from the third-party service. Which of the following cloud computing concepts was MOST likely not properly implemented?

Accepted Answer

High availability. High availability. The VM was migrated to a different physical host during maintenance, which is a normal high-availability operation. However, the static private IP address was not preserved or re-mapped after migration, causing the third-party service to lose connectivity. Proper high-availability implementation requires that the VM's IP address (or a floating IP) remains reachable after failover or migration, typically through mechanisms like virtual IPs, DNS updates, or cloud provider's elastic IP services.

Answer

Elasticity

Answer

Scalability

Answer

Resource pooling

Question 13

A user reports that after a power outage and router restart, their desktop computer can no longer access network shares on other computers. The user can access the internet. The technician runs ipconfig and sees the IP address changed from 192.168.1.50 to 192.168.1.75. The other computers on the network have static IP addresses. Which of the following should the technician configure to resolve the issue permanently?

Accepted Answer

Configure a DHCP reservation on the router for the user's computer.. The user's IP address changed from 192.168.1.50 to 192.168.1.75 after the router restart, indicating the computer received a new DHCP lease. Since other computers use static IPs, the user's computer likely had a static IP before the outage but reverted to DHCP after the restart, or it was always using DHCP and the router assigned a different address. Configuring a DHCP reservation on the router ensures the router always assigns the same IP (192.168.1.50) to the user's MAC address, permanently resolving the connectivity issue to network shares without changing the computer's configuration.

Answer

Configure a static IP address on the user's computer.

Answer

Set a shorter DHCP lease time on the router.

Answer

Change the subnet mask to 255.255.0.0.

Question 14

A user recently purchased a new desktop computer that does not have any USB-C ports. The user wants to add USB-C connectivity to charge devices and transfer data. Which of the following expansion cards should the technician install?

Accepted Answer

PCIe USB 3.0 card with USB-C ports. A PCIe USB 3.0 card with USB-C ports is the correct choice because it directly adds USB-C connectivity to a desktop lacking native ports. USB 3.0 (now USB 3.2 Gen 1) supports up to 5 Gbps data transfer and can provide up to 4.5W (0.9A at 5V) for charging, which meets the user's stated need to charge devices and transfer data. The PCIe interface ensures compatibility with the desktop's expansion slot, making this a straightforward upgrade.

Answer

Thunderbolt 3 PCIe card

Answer

eSATA PCIe card

Answer

FireWire (IEEE 1394) PCIe card

Question 15

A technician is replacing the battery in a smartphone. After reassembly, the phone powers on and the screen works, but the battery icon shows 0% charge and the phone does not recognize the battery. The technician verifies that the battery connector is fully seated. Which of the following should the technician check NEXT?

Accepted Answer

The flex cable connecting the battery to the motherboard is damaged. The battery connector being fully seated does not rule out damage to the flex cable itself. A damaged flex cable can cause an open circuit or intermittent connection between the battery and the motherboard, preventing the battery management system from reading the battery's charge level or identification data, even though the phone powers on via residual charge or a direct power path.

Answer

The battery is defective and needs to be replaced

Answer

The charging port is damaged

Answer

The battery management chip is faulty
