FC0-U71 Tech Concepts and Terminology Practice Test 6 — 15 Questions

Question 1

A graphic designer needs a component to accelerate rendering of 3D models. Which of the following computer hardware components is specifically designed for this purpose?

Accepted Answer

GPU. A GPU (Graphics Processing Unit) is purpose-built with thousands of parallel shader cores optimized for the matrix and vector math used in 3D rendering, making it the correct component to accelerate model rendering. CPUs can render 3D graphics but far more slowly because they have fewer, more general-purpose cores. RAM and SSDs affect capacity and load times, not rendering throughput.

Answer

RAM

Answer

SSD

Answer

CPU

Question 2

Which of the following is the result of the binary operation 1101 AND 1011?

Accepted Answer

1001. The AND operation compares each bit position and outputs 1 only when both input bits are 1. Aligning 1101 and 1011: bit1 1&1=1, bit2 1&0=0, bit3 0&1=0, bit4 1&1=1, giving 1001. This matches option D.

Answer

1111

Answer

1011

Answer

1101

Question 3

A technician is explaining data representation to a trainee. Which TWO of the following are character encoding standards used in computing? (Select TWO).

Accepted Answer

ASCII. ASCII (Option B) is a character encoding standard that maps 128 values (0–127) to English letters, digits, punctuation, and control codes, making it a foundational text-encoding scheme. Unicode/UTF-8 (Option E) is also a character encoding standard; Unicode assigns a unique code point to virtually every character in the world's writing systems, and UTF-8 is its variable-length (1–4 byte) encoding form used widely on the web. The other options are not character encodings: MP3 (A) is an audio compression format, JPEG (C) is an image compression standard, and ZIP (D) is a file archive/compression format, none of which define how characters are represented as numeric codes.

Answer

MP3

Answer

JPEG

Answer

ZIP

Question 4

A company is planning to adopt cloud computing. Which THREE of the following are benefits of using cloud services compared to on-premises infrastructure? (Select THREE).

Accepted Answer

Reduced need for hardware maintenance. Cloud benefits include on-demand resource provisioning (scalability), pay-as-you-go (reduced upfront cost), and reduced maintenance. Guaranteed uptime is not absolute (though SLAs exist), and full control is less in cloud.

Answer

Full control over physical security

Answer

Guaranteed 100% uptime

Question 5

A user notices their computer is running slowly and has many applications open. Which TWO hardware components are most likely to impact the speed at which multiple applications can run simultaneously? (Select TWO).

Accepted Answer

Amount of RAM. Option B (Amount of RAM) is correct because running many applications simultaneously requires enough physical memory to hold each process's working set; when RAM is exhausted, Windows pages data to disk via the pagefile, causing severe slowdowns, so more RAM directly allows more concurrent applications to stay resident in memory. Option E (CPU speed and cores) is correct because the processor executes the instructions for all running applications, and more cores plus higher clock speed let the CPU schedule and execute multiple threads/processes in parallel rather than time-slicing a single core, which is exactly what determines multitasking throughput. Option A (SSD vs HDD) affects storage read/write latency and boot or load times, but it is not the primary factor for keeping many already-running applications responsive. Option C (Hard drive capacity) only concerns how much data can be stored, not how fast multiple apps run. Option D (GPU memory) mainly affects graphics rendering, gaming, and GPU-accelerated workloads, not general multitasking of ordinary applications.

Answer

SSD vs HDD

Answer

Hard drive capacity

Answer

GPU memory

Question 6

A technician needs to convert a decimal IP address octet value of 192 to binary. Which of the following is the correct binary representation?

Accepted Answer

11000000. To convert decimal 192 to binary, decompose it into powers of two: 128 + 64 = 192, so bits 7 and 6 (values 128 and 64) are set to 1 and the remaining six bits are 0. That yields 11000000. This is a standard octet value recognizable as the first octet of a Class C private range (192.168.x.x).

Answer

10101010

Answer

11110000

Answer

10000001

Question 7

A user wants to permanently delete files from a USB flash drive without any possibility of recovery. Which of the following techniques should be used?

Accepted Answer

Overwrite the drive with random data. Overwriting the drive with random data (a multi-pass overwrite) destroys the original file contents at the physical level, making recovery with forensic tools effectively impossible. This is the standard secure-erase technique for USB flash drives and other storage media. Simple deletion or formatting only removes file system references, leaving data recoverable.

Answer

Quick format

Answer

Change the file extension

Answer

Delete and empty Recycle Bin

Question 8

A network technician is troubleshooting a connectivity issue and needs to identify the destination MAC address of a frame. Which TWO of the following are true about MAC addresses? (Select TWO.)

Accepted Answer

They are 48 bits in length. MAC addresses are 48-bit (6 bytes) and commonly represented in hexadecimal. They are assigned by manufacturers and are used at the data link layer.

Answer

They are assigned by the operating system

Answer

They are represented in octal

Answer

They are used at the application layer

Question 9

A user is selecting a storage device for a new computer and wants fast boot times and durability. Which TWO storage technologies should the user consider? (Select TWO.)

Accepted Answer

NVMe SSD. NVMe SSDs and SATA SSDs both use flash memory, delivering fast boot times and no moving parts for durability. NVMe drives connect via PCIe and offer significantly higher throughput and lower latency than SATA SSDs, while standard SSDs remain a cost-effective, durable option. Together they satisfy the 'fast boot times and durability' requirement.

Answer

Optical drive

Answer

HDD (Hard Disk Drive)

Answer

Magnetic tape

Question 10

A technician is explaining the difference between volatile and non-volatile memory to a trainee. Which TWO of the following are examples of volatile memory? (Select TWO.)

Accepted Answer

DDR4 RAM. Volatile memory loses data when power is off. RAM (including DDR4 and DDR5) and cache memory (L1/L2/L3) are volatile. ROM and SSDs are non-volatile.

Answer

ROM

Answer

BIOS firmware

Answer

SSD

Question 11

A help desk technician is comparing storage capacity specifications for two laptops. One specification lists the SSD as 512 GB and the other lists it as 512 GiB. The technician needs to explain to a customer why the operating system reports a lower usable capacity than the advertised number. Which of the following best explains this difference?

Accepted Answer

GB uses powers of 1000 while GiB uses powers of 1024, so the same physical capacity is reported as a smaller number when measured in GiB. The apparent capacity loss occurs because manufacturers advertise decimal gigabytes based on powers of 1000, while many operating systems report binary gibibytes based on powers of 1024. Since a gibibyte is about 7.4 percent larger than a gigabyte, the same physical drive shows a smaller number in GiB. Recognizing this unit distinction lets the technician explain the discrepancy accurately.

Answer

The operating system reserves part of the drive for the file system, so the missing capacity is always exactly the formatting overhead

Answer

GiB measures only the cache portion of the drive while GB measures the full platter area available to the user

Answer

GB is used for solid-state drives and GiB is used for magnetic hard drives, so the two laptops are using different storage technologies

Question 12

A help desk technician is setting up a new laptop for a remote employee. The employee needs to copy a 6 GB video file onto the laptop, which has a 256 GB solid-state drive. Which of the following storage interfaces would provide the fastest transfer speed for an external drive connected to this laptop?

Accepted Answer

USB 3.2 Gen 2. USB 3.2 Gen 2 delivers up to 10 Gbps, making it the fastest among the listed interfaces. For transferring a large 6 GB video file, speed is critical. USB 2.0, eSATA, and FireWire 800 are all slower and less practical for modern laptops. Therefore, USB 3.2 Gen 2 is the best choice.

Answer

FireWire 800

Answer

USB 2.0

Answer

eSATA

Question 13

A junior technician is documenting the internal components of a desktop workstation for an inventory audit. The supervisor asks the technician to identify components that are installed inside the system unit and connect directly to the motherboard or its expansion slots. Which TWO of the following are internal hardware components? (Choose two.)

Accepted Answer

Random access memory module. Internal components are housed within the system unit and connect to the motherboard directly or through expansion slots. RAM modules seat in DIMM slots, and a discrete GPU card occupies a PCIe slot, so both qualify. Peripherals such as webcams, headsets, and network appliances operate externally and therefore do not belong in an inventory of internal hardware.

Answer

Network attached storage appliance

Answer

Bluetooth headset

Answer

External USB webcam

Question 14

A user reports that their desktop computer will not power on. The technician notices that the power supply fan does not spin and no lights appear on the motherboard. The technician has already verified that the wall outlet is working and the power cable is securely connected. Which of the following should the technician check NEXT?

Accepted Answer

The power supply voltage switch. The absence of any power indicators points to a problem with power delivery. After verifying the outlet and cable, the next step is to check the power supply voltage switch, which if set incorrectly can prevent power altogether. RAM, hard drive cables, and CMOS battery would not cause a total lack of power.

Answer

The hard drive data cable

Answer

The RAM modules

Answer

The CMOS battery

Question 15

A user asks a technician why their spreadsheet file opens much faster after being saved in a different format. The technician explains that the new format stores data in a structured, compressed way. Which of the following best describes the primary purpose of a file format?

Accepted Answer

It defines how data is encoded, stored, and interpreted by an application.. A file format defines the encoding and structure that applications use to store and retrieve data. In the scenario, the new format organizes spreadsheet data more efficiently, which explains the faster load time. The other choices describe storage capacity, universal compatibility, or encryption, none of which define what a file format fundamentally does.

Answer

It determines the maximum size of the storage drive that can hold the file.

Answer

It guarantees that the file can be opened by any application on any operating system.

Answer

It encrypts the file contents to prevent unauthorized access by other users.
