220-1101 Practice Test 23 — 15 Questions

Question 1

A user's Android tablet is running low on internal storage. A microSD card has been inserted and formatted as portable storage. The user wants to move some applications to the microSD card to free up space, but the 'Move to SD card' option is grayed out for many apps. Which of the following is the MOST likely reason for this?

Accepted Answer

B. The apps are pre-installed system apps.. Option B is correct because pre-installed system apps are typically stored in a protected system partition that cannot be moved to external storage. Android restricts moving these apps to ensure system stability and security, as they are integral to the device's operation. The grayed-out 'Move to SD card' option indicates that the app's manifest or Android's policy prevents relocation.

Answer

A. The microSD card is not a Class 10 speed card.

Answer

C. The tablet requires a factory reset to enable app moving.

Answer

D. The microSD card is configured as internal storage.

Question 2

A user's smartphone will not charge when connected to the charger. The technician has verified that the charger and cable work with another phone, and the charging port appears clean and free of debris. Which of the following should the technician try FIRST?

Accepted Answer

Use a wireless charger if supported.. Since the charger and cable are verified working and the port is clean, the issue is likely with the phone's charging circuitry. Using a wireless charger (if supported) bypasses the physical charging port entirely, isolating whether the problem is with the port or the phone's internal charging system. This is the quickest and least invasive test before attempting more disruptive steps.

Answer

Replace the battery.

Answer

Perform a hard reset.

Answer

Boot into safe mode.

Question 3

After a thunderstorm, a user reports that their desktop computer cannot connect to the network. The technician observes that the Ethernet port on the computer has a steady green link light but no amber activity light. The switch port corresponding to the user's cable also shows a link light. The computer's operating system shows an IP address of 169.254.1.10. Which of the following is the MOST likely cause?

Accepted Answer

The Ethernet cable has been damaged and is causing frame errors. The 169.254.1.10 IP address is an Automatic Private IP Addressing (APIPA) address (169.254.0.0/16, per RFC 3927), which Windows assigns when DHCP fails. The steady green link light on both the NIC and switch indicates Layer 1 connectivity is intact, but the absence of an amber activity light suggests no data frames are passing. Damaged cabling can cause excessive frame errors or collisions, preventing successful DHCP discovery (broadcast) and data transmission while still allowing the link light to illuminate, as link detection only requires an electrical connection, not error-free communication.

Answer

The network interface card (NIC) has been damaged by a power surge

Answer

The switch port was disabled by the storm

Answer

The router's DHCP server failed after the storm

Question 4

A user's smartphone will not charge when plugged into a wall charger. The technician tests the charger with another phone and it works correctly. The technician then inspects the charging port on the smartphone and notices debris inside. Which of the following is the BEST first step to resolve the issue?

Accepted Answer

Clean the charging port with a toothpick. Option C is correct because the technician has already verified that the charger works with another phone, isolating the issue to the smartphone itself. Inspecting the charging port revealed debris, which is a common cause of poor electrical contact. Cleaning the port with a non-conductive, non-metallic tool like a toothpick is the safest and most effective first step to restore connectivity without damaging the port's pins or internal components.

Answer

Replace the smartphone battery

Answer

Replace the charging port assembly

Answer

Perform a factory reset on the smartphone

Question 5

An administrator is configuring a file server with three identical hard drives. The server requires fault tolerance; it must be able to survive the failure of any one drive without data loss. Additionally, the configuration should maximize usable storage space. Which RAID level should the administrator implement?

Accepted Answer

RAID 5. RAID 5 is the correct choice because it provides fault tolerance for a single drive failure while maximizing usable storage. With three identical drives, RAID 5 uses distributed parity to allow the array to survive any one drive failure without data loss, and the usable capacity is (n-1) drives, or 2 drives' worth of space. RAID 0 offers no redundancy, RAID 1 would waste 2/3 of the capacity with only 1 drive usable, and RAID 10 requires a minimum of 4 drives.

Answer

RAID 0

Answer

RAID 1

Answer

RAID 10

Question 6

After a user updates their iPhone to the latest iOS version, the device can no longer connect to the cellular network. The SIM card is recognized, Wi-Fi works, and the phone can make calls over Wi-Fi (VoWiFi). The technician performed a network settings reset and a full restore from a backup, but the issue persists. Which of the following is the MOST likely cause?

Accepted Answer

The iPhone's baseband hardware has failed. The correct answer is C because the symptoms—SIM recognized, Wi-Fi and VoWiFi working, but no cellular connectivity after an iOS update—point to a hardware-level baseband failure. The baseband processor handles cellular radio functions; an update cannot corrupt hardware, but it can expose a pre-existing latent hardware fault. Since a network settings reset and full restore from backup did not resolve the issue, the problem is not software or firmware, leaving physical baseband hardware failure as the most likely cause.

Answer

The SIM card is damaged or locked to a different carrier

Answer

The iOS baseband firmware is corrupted

Answer

The iOS update introduced a compatibility issue with the carrier

Question 7

An IT administrator is planning a server virtualization project for a small company. The environment must run a mix of modern operating systems (Windows Server, Linux) and one legacy application that requires direct access to a physical PCIe device (e.g., a proprietary capture card). The administrator wants to maximize performance and minimize overhead. Which virtualization type is BEST suited for this requirement?

Accepted Answer

A. Type 1 (bare-metal) hypervisors, such as VMware ESXi or Microsoft Hyper-V, run directly on the host hardware without an underlying OS, providing near-native performance and minimal overhead. This is essential for the legacy application that requires direct PCIe passthrough (e.g., VT-d/IOMMU), as Type 1 hypervisors natively support PCIe device assignment with low latency, while Type 2 hypervisors would add significant overhead and often lack robust PCIe passthrough support.

Answer

B

Answer

C

Answer

D

Question 8

A user's laptop was accidentally knocked off a desk. The laptop powers on and boots to Windows, but the built-in LCD display shows a distorted image with vertical lines and flickering colors. The technician connects an external monitor via HDMI, and the image displays correctly without any distortion. Which of the following components is MOST likely damaged?

Accepted Answer

The LVDS or eDP cable. The correct answer is B because the LVDS (Low-Voltage Differential Signaling) or eDP (Embedded DisplayPort) cable connects the motherboard to the LCD panel. A physical shock from a fall can damage or loosen this internal ribbon cable, causing signal corruption that results in vertical lines and flickering on the built-in display. The fact that an external monitor works perfectly proves the GPU and motherboard are generating a correct video signal, isolating the fault to the display assembly or its interconnect.

Answer

The LCD panel

Answer

The GPU (Graphics Processing Unit)

Answer

The motherboard

Question 9

A technician is building a video editing workstation. The motherboard supports PCIe 4.0, and the installed M.2 NVMe SSD is rated for PCIe 4.0 x4 speeds. The system boots and runs, but benchmarking the SSD shows it only achieves about half of its expected sequential read/write speeds. The technician confirms the SSD is correctly installed in the M.2 slot labeled for PCIe 4.0. Which of the following is the MOST likely cause?

Accepted Answer

The CPU does not support PCIe 4.0. The motherboard supports PCIe 4.0, but the CPU must also support PCIe 4.0 to provide the necessary lanes. If the CPU only supports PCIe 3.0, the M.2 slot will negotiate down to PCIe 3.0 speeds, cutting the bandwidth in half (from ~7.9 GB/s to ~3.9 GB/s), which matches the symptom of achieving about half the expected sequential read/write speeds.

Answer

The SSD is a SATA-based M.2 drive, not NVMe

Answer

The M.2 slot shares bandwidth with a SATA port that is occupied

Answer

The motherboard BIOS has a secure erase setting enabled

Question 10

A technician is repairing a smartphone that has a cracked screen. The glass is shattered but the LCD and digitizer underneath are functional except for unresponsive touch in some areas. The user wants all data preserved. After disconnecting the battery, which tool is MOST critical for safely lifting the cracked glass to access the internal components?

Accepted Answer

Suction cup. The suction cup is the most critical tool for safely lifting the shattered glass because it provides a controlled, even pulling force to separate the glass from the frame without further damaging the underlying LCD and digitizer. Since the glass is cracked but the LCD and digitizer are still functional, using a suction cup minimizes the risk of applying uneven pressure that could crack the LCD or tear the digitizer flex cables. This tool is essential for preserving data by avoiding additional damage to the display assembly during disassembly.

Answer

Screwdriver set

Answer

Spudger

Answer

Magnifying glass

Question 11

A technician is replacing the power supply unit in a desktop computer. The new PSU is correctly rated for the system and the technician connects the 24-pin main motherboard connector and the 4+4 pin CPU power connector. When the power button is pressed, the system does not power on; no fans spin and no LEDs light up. The technician verifies that the PSU's power switch is on and that the wall outlet is functional. Using a multimeter, the technician confirms that the PSU outputs correct voltages on the 24-pin connector when the paperclip test is performed. Which of the following is the MOST likely cause of the issue?

Accepted Answer

The 4+4 pin CPU power connector is not fully seated in the motherboard's EPS connector.. The 4+4 pin CPU power connector provides dedicated 12V power to the CPU VRM. If it is not fully seated, the motherboard's power delivery system will detect an open circuit and prevent the system from starting, even though the main 24-pin connector and PSU itself are functional. The paperclip test confirms the PSU can output correct voltages under no load, but it does not verify that the EPS connector is properly engaged.

Answer

The PSU is not compatible with the motherboard's power requirements.

Answer

The motherboard is shorting against the case.

Answer

The power button header is connected to the wrong pins.

Question 12

A technician is setting up a small office network. The ISP provides a cable modem with a single Ethernet port. The office has 15 computers that all need internet access. The technician has a router with four LAN ports and a 24-port unmanaged switch. Which of the following is the correct way to connect the devices to provide internet access to all computers?

Accepted Answer

Connect the modem to the router's WAN port, then connect the switch to one of the router's LAN ports, and connect all computers to the switch.. Option B is correct because the router's WAN port is designed to connect to the ISP modem for public IP assignment via DHCP, while the LAN ports provide private IP addresses to internal devices. The switch connects to a LAN port to expand the number of available ports, allowing all 15 computers to access the internet through the router's NAT and routing functions.

Answer

Connect the modem to one of the router's LAN ports, then connect the switch to another LAN port, and connect all computers to the switch.

Answer

Connect the modem directly to the switch, then connect the router to the switch, and connect all computers to the router's LAN ports.

Answer

Connect the modem to one of the switch's ports, then connect the router to another switch port, and connect all computers to the router.

Question 13

A technician is installing a new CPU on a motherboard. The CPU is properly oriented and seated, but the retention arm will not close. What is the MOST likely issue?

Accepted Answer

Bent pins on the motherboard. If the CPU is properly oriented and seated but the retention arm will not close, the most likely cause is bent pins on the motherboard (LGA socket) or on the CPU (PGA socket). Bent pins prevent the CPU from sitting flush, creating mechanical interference that stops the arm from latching. This is a common issue when handling the CPU or socket carelessly.

Answer

Wrong CPU socket type

Answer

Too much thermal paste

Answer

CPU not aligned with the socket key

Question 14

A technician is building a workstation and installs two 16 GB DDR4-3200 memory modules into a motherboard with four DIMM slots: A1, A2, B1, B2. The modules are installed in slots A1 and B2. After powering on, the system detects only 16 GB of RAM. Which of the following is the MOST likely cause?

Accepted Answer

The modules are not installed in the correct slots for dual-channel operation. The motherboard's DIMM slots are typically arranged in pairs (A1/A2 and B1/B2) for dual-channel memory operation. Installing modules in A1 and B2 skips the paired configuration required for dual-channel mode; many motherboards will only recognize one module (16 GB) if the slots are not populated in the correct order, often defaulting to single-channel operation and ignoring the second module. The correct slots for dual-channel would be A1 and B1 (or A2 and B2) to enable both modules to be detected as 32 GB.

Answer

One of the memory modules is faulty

Answer

The BIOS needs to be updated

Answer

The memory voltage is set incorrectly

Question 15

A technician is building a PC for a user who needs to run multiple virtual machines. The motherboard supports a maximum of 32GB of RAM across 4 DIMM slots. Currently, two 8GB modules are installed. The user requires at least 32GB of RAM total, and the technician wants to reuse the existing modules. Which of the following is the MOST cost-effective upgrade?

Accepted Answer

Add two additional 8GB modules. Option A is correct because the motherboard supports up to 32GB across 4 DIMM slots, and two 8GB modules are already installed. Adding two more 8GB modules fills all slots and achieves 32GB total, reusing the existing modules without waste. This is the most cost-effective solution since 8GB modules are typically cheaper per gigabyte than 16GB modules, and no modules are discarded.

Answer

Replace the two 8GB modules with two 16GB modules

Answer

Add one 16GB module

Answer

Replace all modules with four 8GB modules
