FC0-U71 Practice Test 23 — 15 Questions

Question 1

A small business needs a printer that can produce high-quality color documents quickly and at a low cost per page. Which type of printer is most suitable?

Accepted Answer

Laser printer. A color laser printer is the best fit because it delivers fast print speeds, sharp text and graphics, and a low cost per page when compared with inkjet for sustained business use. Laser technology uses toner rather than liquid ink, so color documents do not smudge and consumables last much longer. For a small business producing high-quality color output quickly, laser is the standard recommendation.

Answer

Dot matrix printer

Answer

Thermal printer

Answer

Inkjet printer

Question 2

A company's email server is experiencing slow performance. The IT administrator notices high disk I/O wait times. Which component is most likely bottlenecked?

Accepted Answer

Storage. High disk I/O wait times indicate that the storage subsystem is struggling to keep up with read/write requests, causing the CPU to idle while waiting for data from the disk. This is a classic symptom of a storage bottleneck, not a CPU, network, or memory issue.

Answer

CPU

Answer

Network

Answer

RAM

Question 3

A user reports that they can access websites by IP address but not by domain name. Based on the exhibit, which of the following is the MOST likely cause?

Accepted Answer

Incorrect or unreachable DNS server. The user can access websites by IP address but not by domain name, which indicates that IP routing and connectivity are functioning correctly. The failure to resolve domain names points directly to a DNS issue, such as an incorrect or unreachable DNS server. DNS translates human-readable domain names into IP addresses; without a working DNS server, name resolution fails while direct IP access remains unaffected.

Answer

Duplicate IP address on the network

Answer

Incorrect default gateway

Answer

Incorrect subnet mask

Question 4

A user wants to upgrade their laptop's storage to improve boot times and file transfer speeds. The laptop has an available M.2 slot. Which type of drive should the user choose?

Accepted Answer

NVMe M.2 SSD. An NVMe M.2 SSD uses the PCIe bus and the NVMe protocol, delivering far higher sequential and random I/O than SATA-based drives — directly improving boot times and file transfer speeds. Since the laptop has an M.2 slot, an NVMe M.2 drive is the correct high-performance choice. It is also the form factor that maximizes the slot's potential.

Answer

2.5-inch SATA HDD

Answer

SATA M.2 SSD

Answer

External USB 3.0 HDD

Question 5

A database administrator wants to enforce that a column only accepts whole numbers. Which data type should be used?

Accepted Answer

Integer. The INTEGER data type is specifically designed to store whole numbers without fractional components. In database systems, enforcing a column to accept only whole numbers requires a data type that disallows decimal points, which INTEGER does by definition. Using INTEGER ensures data integrity by rejecting any non-integer input, such as 3.14 or 'abc'.

Answer

String

Answer

Boolean

Answer

Float

Question 6

Refer to the exhibit. A user is able to browse the internet using the Ethernet connection but not the Wi-Fi. What is the most likely cause?

Accepted Answer

The Wi-Fi adapter is not connected to any network. The exhibit shows that the Ethernet interface has an IP address (192.168.1.114) and is connected to the internet, while the Wi-Fi interface shows 'Not connected' with no IP address assigned. Since the user can browse the internet via Ethernet but not Wi-Fi, the most likely cause is that the Wi-Fi adapter is not connected to any network, meaning it has not associated with a wireless SSID or obtained an IP address via DHCP.

Answer

The Wi-Fi adapter is disabled

Answer

The DNS suffix is missing

Answer

The default gateway is incorrect

Question 7

A user is selecting a new computer and sees that the CPU has a clock speed of 3.6 GHz and four cores. What does the clock speed of 3.6 GHz indicate?

Accepted Answer

The number of billions of cycles per second. Clock speed (GHz) indicates how many billions of cycles per second the CPU can execute. It does not directly indicate cache size, core count, or power consumption.

Answer

The number of instructions per cycle

Answer

The power consumption of the CPU

Answer

The amount of cache memory available

Question 8

A small business wants to set up a wireless network for employees and guests. The owners are concerned about unauthorized access. Which of the following security measures would be MOST effective to prevent outsiders from connecting?

Accepted Answer

Use WPA2 encryption with a strong passphrase. WPA2 encryption with a strong passphrase is the most effective measure because it encrypts all wireless traffic and requires authentication before a device can join the network. Without the correct pre-shared key (PSK), an attacker cannot decrypt the data or gain access, even if they can see the network. This directly prevents unauthorized outsiders from connecting, unlike the other options which are easily bypassed.

Answer

Enable MAC address filtering

Answer

Disable SSID broadcast

Answer

Disable DHCP on the router

Question 9

A user is trying to install software from an .msi file on a Windows computer. What is the most likely purpose of an .msi file?

Accepted Answer

It is a Microsoft Installer package that automates software installation.. An .msi file is a Microsoft Installer package — a structured database file that contains installation instructions, file manifests, registry entries, and rollback information used by the Windows Installer service (msiexec.exe) to install, modify, or remove software. It is not a simple archive; it drives a transactional installation process.

Answer

It is a compressed archive like a .zip file.

Answer

It is a script that downloads software from the internet.

Answer

It is a configuration file for Windows settings.

Question 10

An administrative assistant is using a spreadsheet application to create a budget report. The assistant needs to add a column that calculates the total of the previous three columns for each row. The assistant is not very experienced with formulas and is unsure how to proceed. The assistant wants to use a built-in function that will automatically sum the values. Which of the following should the assistant do to achieve this?

Accepted Answer

Use the SUM function in a formula to add the three cells.. The SUM function is the correct built-in function in spreadsheet applications (like Microsoft Excel or Google Sheets) to add a range of cells. By using a formula such as =SUM(A2:C2), the assistant can automatically calculate the total of the three columns for each row without manual errors. This directly meets the requirement to sum values efficiently.

Answer

Manually type each cell reference separated by plus signs.

Answer

Use the COUNT function to count the number of cells.

Answer

Use the AVERAGE function to find the average of the values.

Question 11

A computer has 8 GB of RAM installed, but the operating system reports only 7.9 GB usable. What is the most likely reason for this discrepancy?

Accepted Answer

Some RAM is reserved for hardware devices. The most likely reason is that some RAM is reserved for hardware devices. This is a standard behavior where system resources, such as memory-mapped I/O (MMIO), are allocated to hardware components like the GPU, network adapters, and PCIe devices. This reservation reduces the total usable RAM reported by the operating system, even though 8 GB is physically installed.

Answer

The operating system itself uses too much RAM

Answer

The operating system is 32-bit

Answer

The RAM is not installed in dual-channel mode

Question 12

A company is setting up a new office and needs to connect multiple computers within the same building to share files and printers. Which type of network should they implement?

Accepted Answer

LAN. A LAN (Local Area Network) connects devices within a single building or campus to share files, printers, and other resources. The scenario describes multiple computers in one building sharing resources, which is the textbook definition of a LAN. WANs span large geographic areas, PANs are personal-range, and WLANs are wireless-specific.

Answer

WAN

Answer

PAN

Answer

WLAN

Question 13

Which TWO of the following are examples of output devices?

Accepted Answer

Monitor. A monitor is an output device because it receives processed data from the computer's graphics card and displays it visually to the user. Output devices convert electronic signals into human-readable form, such as text, images, or video, which is exactly what a monitor does.

Answer

Scanner

Answer

Keyboard

Answer

Mouse

Question 14

A user wants to install a 32-bit application on a 64-bit version of Windows 10. The application's installer runs but displays an error message stating that the application requires a 32-bit operating system. Which of the following is the most likely cause?

Accepted Answer

The application is designed to only run on a 32-bit operating system.. The error message explicitly states that the application requires a 32-bit operating system. This indicates that the application's code is written to only run on a 32-bit OS, often due to reliance on 16-bit components or kernel-mode drivers that are not supported in the 64-bit Windows environment. Windows 10 64-bit includes WOW64 (Windows 32-bit on Windows 64-bit) to run most 32-bit applications, but some legacy applications are hard-coded to check for a 32-bit OS and will refuse to run on 64-bit.

Answer

The user needs to run the installer in compatibility mode for 32-bit.

Answer

The installer is corrupted and needs to be re-downloaded.

Answer

The application requires drivers that are not available for 64-bit.

Question 15

In which phase of the Software Development Life Cycle (SDLC) are the system requirements gathered and analyzed?

Accepted Answer

Analysis. The Analysis phase (also called Requirements Analysis or Requirements Gathering) is specifically dedicated to eliciting, documenting, and validating stakeholder needs and system requirements. During this phase, business analysts and developers work with stakeholders to define functional and non-functional requirements, often producing artifacts like a Software Requirements Specification (SRS). This is distinct from planning, which focuses on feasibility and project scope, and design, which translates requirements into technical blueprints.

Answer

Implementation

Answer

Design

Answer

Planning
