FC0-U71 Practice Test 37 — 15 Questions

Question 1

A developer is using Git and wants to integrate changes from a feature branch into the main branch. Which Git operation should be performed?

Accepted Answer

Merge. The 'git merge' command integrates changes from one branch into another, typically merging a feature branch into the main branch. It combines the commit histories and creates a merge commit if necessary, preserving the context of both branches.

Answer

Branch

Answer

Commit

Answer

Clone

Question 2

Refer to the exhibit. A technician is investigating a computer that randomly restarts. Based on the log, what should the technician check?

Accepted Answer

Power supply and connections. The log shows a 'Kernel-Power' event (ID 41) with no clear error before the restart, which typically indicates an unexpected loss of power. This points directly to a failing power supply or loose connections, as the system cannot maintain stable voltage under load. Checking the power supply and its connections is the first step in diagnosing random restarts caused by power instability.

Answer

CPU cooling fan for proper operation

Answer

Recently installed device drivers

Answer

Memory modules for errors

Question 3

A system administrator needs to deploy a software update to 500 computers without user interaction. Which installation method should be used?

Accepted Answer

Run the installer with the /quiet or /silent switch. Running the installer with /quiet or /silent switches performs a silent installation, which requires no user interaction and can be scripted or pushed to many machines. This is the correct method for deploying an update to 500 computers unattended. The other options either require user action or are impractical at scale.

Answer

Email the installer to each user and ask them to run it

Answer

Copy the program files manually to each computer

Answer

Install from an app store

Question 4

A digital image is stored in a file that retains all original data without any loss. Later, the file is compressed using a technique that discards some data to reduce file size, but the image quality is lower. Which type of compression was applied?

Accepted Answer

Lossy compression. Lossy compression permanently discards some data to achieve smaller file sizes, and the resulting image quality is reduced — which matches the scenario where the file was originally lossless but then compressed with quality loss. The question explicitly states that data is discarded and quality is lower, which is the defining characteristic of lossy compression.

Answer

Archive compression

Answer

Lossless compression

Answer

File compression

Question 5

A user downloads a software installer from the internet. On Windows, which file extension is most likely to be used for the installer?

Accepted Answer

.exe. On Windows, the standard file extension for executable programs and software installers is .exe (executable). When a user downloads an installer for Windows, it is typically an .exe file that can be run to install the application. The other extensions are associated with different operating systems: .pkg and .dmg are used on macOS, and .deb is used on Debian-based Linux distributions.

Answer

.pkg

Answer

.deb

Answer

.dmg

Question 6

An IT administrator needs to install software on multiple company computers without user interaction. Which installation method should the administrator use?

Accepted Answer

Silent installation. A silent installation runs the installer with no user interaction, using command-line switches (e.g., /quiet, /silent, /S) so it can be deployed unattended across many machines. This is the standard method for mass deployment without user involvement. Network installation refers to installing from a shared network location, but it can still prompt the user; silent installation specifically addresses the no-interaction requirement.

Answer

App store installation

Answer

Interactive installation

Answer

Network installation

Question 7

A junior programmer is reviewing a piece of pseudocode written by a teammate. The pseudocode contains the line: total = total + item. The programmer wants to know what type of operation this line performs in the algorithm. Which of the following best describes this line?

Accepted Answer

It assigns the sum of total and item back to total.. The statement total = total + item is an assignment that adds the current value of total to item and stores the result back into total. This accumulator pattern is used to keep a running sum while processing items in a loop. It is not a comparison, declaration, or output statement, so the correct description is that it assigns the sum back to total.

Answer

It outputs the value of total and item to the user.

Answer

It declares total as a new variable of type item.

Answer

It performs a comparison between total and item.

Question 8

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 9

A small business has a single server that hosts a customer database. The owner wants to ensure the database remains available if the server's primary power supply fails. Which component should the technician install to meet this need?

Accepted Answer

A redundant power supply. The owner needs the server to stay online if its power supply fails, which is exactly what a redundant power supply provides. Extra CPU, RAM, or storage improves performance or capacity but leaves the server vulnerable to a single power failure. Only a second power supply removes that single point of failure.

Answer

A larger hard drive

Answer

Additional RAM

Answer

A second CPU

Question 10

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 11

A user reports that a laptop battery no longer holds a charge and the laptop shuts down immediately when unplugged. The laptop is several years old and the user wants to keep using it. Which of the following is the most appropriate replacement component?

Accepted Answer

A new laptop battery compatible with the model. A battery that no longer holds a charge and causes immediate shutdown when unplugged is failing and should be replaced with a compatible unit. Power adapters, motherboards, and RAM do not address battery capacity loss. Replacing the battery is the correct, targeted repair that restores portable use.

Answer

A higher-wattage power adapter

Answer

An additional RAM module

Answer

A replacement motherboard

Question 12

A developer is debugging a program that crashes with an error. Which THREE of the following are common debugging techniques?

Accepted Answer

Stepping through code line by line. Option A (Stepping through code line by line) is correct because executing code one statement at a time in a debugger lets the developer observe the exact instruction where the crash occurs and trace the control flow leading up to it. Option D (Setting breakpoints to pause execution) is correct because breakpoints halt the program at a chosen line or condition, allowing the developer to examine the program state at the critical moment before the error manifests. Option E (Inspecting variable values during execution) is correct because examining variables, registers, and memory at runtime reveals incorrect values, null references, or out-of-range data that explain the crash. Option B (Ignoring the error and continuing) is not a debugging technique since it provides no diagnostic information and typically lets the fault propagate or recur. Option C (Recompiling the entire program without changes) is not a debugging technique because rebuilding identical source produces the same binary behavior and yields no new insight into the defect.

Answer

Ignoring the error and continuing

Answer

Recompiling the entire program without changes

Question 13

A technician must install an internal storage drive in a desktop that will hold the operating system and needs the fastest practical boot performance. The motherboard supports NVMe and has an available M.2 slot wired for PCIe. Which drive should the technician select?

Accepted Answer

An M.2 NVMe SSD. The M.2 slot is wired for PCIe, so an NVMe drive can use those lanes directly and deliver the highest throughput available in this system. SATA-based options, whether 2.5-inch or M.2 form factor, are capped by the slower SATA protocol, and a mechanical disk is slower still.

Answer

A 7200 RPM SATA hard disk

Answer

A 2.5-inch SATA SSD

Answer

An M.2 SATA SSD

Question 14

A user complains that their laptop battery drains rapidly even while plugged into a docking station that supports USB Power Delivery. The dock is connected with a cable that fits the USB-C port. Which of the following is the MOST likely cause?

Accepted Answer

The dock provides less power than the laptop requires under its current workload.. USB Power Delivery allows a charger and device to agree on a wattage both support. When the dock's maximum output is lower than what the laptop consumes during demanding tasks, the shortfall is drawn from the battery, so the charge level falls even though the dock is connected. Checking the dock's rated wattage against the laptop's power adapter rating reveals the mismatch.

Answer

The docking station is using the USB 2.0 protocol instead of USB 3.2.

Answer

The laptop's battery is failing and can no longer hold a charge.

Answer

The USB-C cable is a charge-only cable and cannot carry data.

Question 15

A company is virtualizing several physical servers onto one host. The administrator wants to isolate each virtual machine so that a crash or resource spike in one does not affect the others, while still sharing the physical CPU and memory. Which technology should the administrator rely on?

Accepted Answer

A hypervisor. Virtual machines share a host's CPU and memory through a hypervisor, which enforces isolation so one VM's crash or resource spike does not disrupt the others. RAID, switches, and load balancers serve storage, networking, and traffic distribution roles respectively, but none of them virtualizes compute resources.

Answer

A load balancer

Answer

A RAID controller

Answer

A network switch
