Which of the following virtualization features should be implemented to achieve this goal?

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

Accepted Answer

Fault tolerance. Fault tolerance (B) is correct because it creates a secondary, shadow virtual machine that runs in lockstep with the primary VM. If the physical host fails, the secondary VM takes over instantly with no data loss or downtime, ensuring the database server remains operational.

Answer

Live migration

Answer

Load balancing

Answer

Snapshot

Question 2

A user reports that their desktop computer, connected to a network printer via Ethernet, outputs garbled text when printing. The same user can print correctly using a USB connection to the same printer. Other users on the same network can print to the printer normally. The technician has already reinstalled the printer driver on the user's computer. Which of the following should the technician check NEXT?

Accepted Answer

Examine the printer driver properties and advanced settings, such as print processor or default language. The issue is specific to network printing on one workstation, with USB printing working fine and other network users unaffected. This isolates the problem to the print processor or data format handling on that client. Reinstalling the driver didn't fix it, so the next step is to check the driver's advanced settings, such as the print processor (e.g., WinPrint vs. HP Standard) or the default data type (e.g., RAW vs. EMF), which can cause garbled output if mismatched with the printer's PDL interpretation.

Answer

Verify the printer's network configuration via its control panel

Answer

Check the network cable and switch port for the printer

Answer

Update the firmware on the network printer

Question 3

A user's smartphone has a cracked screen. The display is still visible, but the touch input is only partially responsive. The user needs to perform a factory reset to erase personal data before selling the device. The user can see the 'Reset' button on the screen but cannot tap it due to the unresponsive area. Which of the following methods would be the MOST effective way to perform the factory reset?

Accepted Answer

Connect a USB mouse via an OTG adapter to navigate the interface and tap the reset button.. An OTG (On-The-Go) adapter allows connecting a USB mouse directly to the smartphone, enabling precise cursor control. This bypasses the unresponsive touch area, letting the user navigate to and tap the 'Reset' button without needing functional touch input on that portion of the screen.

Answer

Use the volume buttons and power button to navigate the recovery menu to perform a factory reset from recovery mode.

Answer

Use the manufacturer's online account portal (e.g., Find My Device) to remotely wipe the device.

Answer

Install a third-party backup app that can initiate a factory reset from the app's settings.

Question 4

A technician is troubleshooting a user's workstation that has intermittent network connectivity. The technician observes that the Ethernet link light on the workstation's NIC flashes irregularly and occasionally stays off for a few seconds. The cable passes a wiremap test. The switch port is configured for auto-negotiation. Which of the following is the MOST likely cause?

Accepted Answer

Electromagnetic interference from nearby power cables.. The intermittent flashing and occasional off periods of the Ethernet link light, combined with a passing wiremap test, strongly indicate that the signal is being corrupted by external interference. Electromagnetic interference (EMI) from nearby power cables can disrupt the differential signaling on twisted-pair copper cabling, causing link drops and flapping link lights even when the physical wiring is intact. This matches the symptom of a link light that flashes irregularly and stays off for seconds, as the NIC and switch repeatedly lose and re-establish the link due to noise.

Answer

The cable is too long (exceeds 100 meters).

Answer

The workstation's IP address is a duplicate.

Answer

The NIC driver is out of date.

Question 5

A technician is building a high-performance gaming PC for a client. The technician installs a motherboard that supports DDR4-3200, an Intel Core i7-10700K CPU, and 32 GB (2 x 16 GB) of DDR4-3600 RAM rated at 1.35V. The system boots normally, but the BIOS reports the RAM running at 2133 MHz. The technician enables XMP Profile 1 in the BIOS, but the system fails to POST and must be reset via CMOS clear. After clearing CMOS, the system boots again at 2133 MHz. The technician has verified that the CPU and motherboard support DDR4-3200. Which of the following is the MOST likely cause of the failure?

Accepted Answer

The RAM speed is higher than the motherboard's supported maximum. The motherboard supports DDR4-3200, but the installed RAM is rated at DDR4-3600, which exceeds the motherboard's maximum supported speed. When XMP Profile 1 is enabled, it attempts to run the RAM at 3600 MHz, causing the system to fail POST because the motherboard's memory controller cannot reliably handle that speed. The CMOS clear restores default settings, returning the RAM to the JEDEC standard 2133 MHz.

Answer

The RAM modules are not installed in the correct slots for dual-channel mode

Answer

The XMP profile requires a higher voltage than the motherboard can provide

Answer

The CPU does not support any RAM speed above 2133 MHz

Question 6

A technician is troubleshooting a laser printer that produces pages with a horizontal black line across the top of every page. The line is the same width as the page and appears in the same location each time. The technician has already replaced the toner cartridge and the imaging drum. Which of the following printer components should the technician check NEXT?

Accepted Answer

Fuser. The fuser assembly uses heat and pressure to permanently bond toner to the paper. A damaged fuser roller (e.g., a nick, scratch, or melted toner buildup) will imprint a consistent horizontal line across the top of every page because the defect contacts the paper at the same rotational point each time. Replacing the toner cartridge and imaging drum did not resolve the issue, confirming the problem is downstream in the fuser.

Answer

Transfer roller

Answer

Primary corona wire (or charge roller)

Answer

Pickup rollers

Question 7

A user's desktop computer does not boot and emits a series of long beeps. After checking the motherboard documentation, the technician confirms the beep code indicates a memory issue. Which of the following should the technician do FIRST?

Accepted Answer

Reseat the RAM modules. The beep code indicates a memory issue, and the most common cause is loose or improperly seated RAM modules. Reseating the RAM is the simplest, fastest, and least invasive first step to ensure proper contact between the memory module and the motherboard slot.

Answer

Replace the motherboard

Answer

Replace the power supply

Answer

Update the BIOS firmware

Question 8

A company wants to move its email system to the cloud. The IT team wants to avoid managing the underlying servers and email software but needs full administrative control over email settings, user accounts, and security policies. Which cloud service model should the company choose?

Accepted Answer

Software as a Service (SaaS). Software as a Service (SaaS) delivers the email application over the internet, with the provider managing the underlying servers, operating systems, and email software. This model allows the company to avoid server and software management while retaining full administrative control over email settings, user accounts, and security policies through the application's management interface. Examples include Microsoft 365 Exchange Online and Google Workspace.

Answer

Infrastructure as a Service (IaaS)

Answer

Platform as a Service (PaaS)

Answer

Desktop as a Service (DaaS)

Question 9

A user reports that during phone calls, the person on the other end cannot hear them. The user can hear the caller clearly. The user can also record voice memos and videos with sound without any issues. Which of the following components is MOST likely faulty?

Accepted Answer

Noise-cancellation microphone. The noise-cancellation microphone is the most likely faulty component because it is specifically designed to pick up the user's voice while filtering out ambient noise. During phone calls, the primary microphone handles voice transmission, but if the noise-cancellation mic fails, it can cause the system to misinterpret the user's speech as background noise and suppress it, resulting in the caller not hearing the user. The fact that voice memos and videos record correctly indicates the main microphone is functional, isolating the issue to the secondary microphone used for noise cancellation during calls.

Answer

Earpiece speaker

Answer

Loudspeaker

Answer

Charging port

Question 10

A user is unable to print to a network printer. Other users on the same network can print to it successfully. The technician checks the user's workstation and confirms it has a valid IP address on the correct subnet. The printer's network cable is plugged in, and the link lights are active. Which of the following should the technician check FIRST?

Accepted Answer

The user's printer driver configuration. Since other users can print to the network printer successfully, the printer itself, its network connectivity, and the switch port are all functioning correctly. The issue is isolated to the user's workstation, and a valid IP address on the correct subnet indicates basic network connectivity is present. Therefore, the most likely cause is a misconfigured or corrupted printer driver on the user's machine, making the printer driver configuration the first thing to check.

Answer

The printer's toner or ink levels

Answer

The switch port that the printer is connected to

Answer

The network cable connecting the printer

Question 11

A technician is troubleshooting a laser printer that produces pages with faint images. The toner cartridge is full and the imaging drum has been replaced recently. The technician prints a test page from the printer's control panel, which also appears faint. Which of the following components should the technician check or replace NEXT?

Accepted Answer

The primary charge roller (or corona wire).. The primary charge roller (or corona wire) applies a uniform electrostatic charge to the photosensitive drum. If it is worn, dirty, or failing, the drum cannot hold a proper charge, resulting in a faint image even with a full toner cartridge and a new drum. The test page being faint confirms the issue is in the image formation process, not the data path.

Answer

The fuser assembly.

Answer

The transfer roller.

Answer

The paper pickup rollers.

Question 12

A user reports that their smartphone's Bluetooth will not pair with their car's hands-free system after a recent OS update. The car's system has been successfully paired with other phones. The technician has reset the phone's network settings and forgotten the car from the Bluetooth list, but the pairing still fails. Which of the following should the technician try NEXT?

Accepted Answer

Check for a firmware update for the car's infotainment system. The car's system works with other phones, so the issue is likely an incompatibility introduced by the smartphone's OS update. Checking for a firmware update for the car's infotainment system is the next logical step because the car's Bluetooth stack may need an update to maintain compatibility with the new OS version's Bluetooth profiles or security requirements (e.g., LE Secure Connections).

Answer

Perform a factory reset of the smartphone

Answer

Replace the Bluetooth antenna in the smartphone

Answer

Disable Wi-Fi on the smartphone before pairing

Question 13

A technician is building a new desktop PC from components. After installing the motherboard, CPU, RAM, and power supply, the technician needs to connect the front panel power switch to the motherboard. Which of the following motherboard headers should the technician connect the power switch cable to?

Accepted Answer

PWR_BTN (Power Button) or POWER_SW header. The front panel power switch cable must be connected to the motherboard header labeled PWR_BTN or POWER_SW. This header completes a momentary contact circuit that signals the power supply to turn on when the switch is pressed, initiating the system boot sequence.

Answer

PWR_LED (Power LED) header

Answer

RESET (Reset Button) header

Answer

SPEAKER header

Question 14

A network technician configures a managed switch with two VLANs: VLAN 10 for workstations and VLAN 20 for servers. A workstation on VLAN 10 can ping its default gateway (192.168.10.1), and a server on VLAN 20 can ping its default gateway (192.168.20.1). However, the workstation cannot ping the server's IP address (192.168.20.10). All switch ports are configured as access ports in their respective VLANs, and the default gateways are correctly assigned. Which of the following is MOST likely needed to allow this communication?

Accepted Answer

A router configured for inter-VLAN routing. The workstation and server are on different VLANs, which are separate Layer 2 broadcast domains. Even though each device can reach its own default gateway, communication between VLANs requires a Layer 3 device to route packets between them. A router configured for inter-VLAN routing (either router-on-a-stick or a Layer 3 switch) is necessary to forward traffic from VLAN 10 to VLAN 20.

Answer

A DHCP server on each VLAN

Answer

A higher category Ethernet cable

Answer

A trunk port between the switch and the router

Question 15

A user reports that their desktop computer randomly restarts during gaming sessions. The technician has replaced the power supply unit (PSU) with a known-good unit of higher wattage, verified that CPU and GPU temperatures remain within normal limits during gaming, and updated all drivers. The RAM passes a memory test. Which of the following should the technician check NEXT?

Accepted Answer

Check the wall outlet voltage with a multimeter.. The technician has already ruled out the PSU, overheating, driver issues, and faulty RAM. Random restarts under load can be caused by unstable or insufficient AC power from the wall outlet. Using a multimeter to check the wall outlet voltage is the logical next step to identify if the issue is upstream of the PSU, such as a sagging voltage or a loose neutral connection.

Answer

Replace the motherboard.

Answer

Disable automatic restart in Windows System Properties.

Answer

Run a stress test on the GPU.
