FC0-U71 Applications and Software Practice Test 8 — 15 Questions

Question 1

A user wants to install a locally compiled C program on a Linux system so that it becomes available system-wide to all users. Which command should the user run from the source directory after compilation?

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

Accepted Answer

sudo make install. Installing locally compiled software on Linux requires copying the built artifacts into system directories, which is exactly what the make install target does. Because standard install locations such as /usr/local/bin are owned by root, the operation must be elevated with sudo. Compiling with make alone or merely changing permissions does not make the program available system-wide.

Answer

chmod +x program

Answer

sudo apt-get install ./program

Answer

make

Question 2

A technician is preparing a workstation for a user who needs to work with several document types. The technician wants to confirm which file extensions are commonly associated with word-processing documents and which are commonly associated with spreadsheets. Which TWO file extensions are typically used for spreadsheet files? (Choose two.)

Accepted Answer

.csv. Spreadsheet applications work with row-and-column data, and the extensions most closely tied to that model are .xlsx for native workbooks and .csv for plain-text tabular data. Word-processing, presentation, and portable document formats serve different content types and open in different applications, so they are not spreadsheet extensions. Recognizing these associations helps a technician map file types to the right software.

Answer

.pdf

Answer

.pptx

Answer

.docx

Question 3

A user wants to open a spreadsheet file, edit some cells, and then save the changes in a format that preserves formulas and formatting. Which type of application should the user open?

Accepted Answer

A spreadsheet application. A spreadsheet application is the correct tool because it is purpose-built for cell-based data entry, formula calculation, and formatted workbooks. Word processors, presentation tools, and database managers each serve different content types and cannot preserve spreadsheet formulas and cell formatting in the way the user requires.

Answer

A word processing application

Answer

A database management application

Answer

A presentation application

Question 4

A software development team is using a version control system to manage their codebase. They want to create an isolated copy of the main codebase to develop a new feature without affecting the main line of development. Which Git operation should they use?

Accepted Answer

git branch. git branch is the correct operation because it creates a new branch, which is an isolated line of development. This allows the team to work on the feature without affecting the main branch. git commit records changes, git merge combines branches, and git clone copies a repository. Only branching provides the required isolation for feature development.

Answer

git merge

Answer

git commit

Answer

git clone

Question 5

A technician is explaining the concept of software licensing to a client. The client wants to install a single copy of an application on multiple computers within their small business. Which type of license should the technician recommend?

Accepted Answer

Site license. A site license grants an organization the right to install and use a software application on multiple computers at a single physical location, such as a small business. It is the most cost-effective and legal way to cover all employees at that site. Other license types typically restrict installation to a single computer or have terms that do not fit a multi-computer business environment.

Answer

Single-user license

Answer

Freeware license

Answer

Open-source license

Question 6

A spreadsheet user needs to display the text from cell A2 in all uppercase letters in cell B2, without altering the original value in A2. Which function should be entered in B2?

Accepted Answer

=UPPER(A2). The UPPER function is the correct tool because it returns an uppercase copy of the referenced text without modifying the source cell. Functions like LOWER and PROPER change case in different ways, and CONCATENATE only joins strings. Only UPPER converts every character in A2 to uppercase while leaving the original data intact.

Answer

=LOWER(A2)

Answer

=CONCATENATE(A2)

Answer

=PROPER(A2)

Question 7

A user is evaluating database concepts while building a small inventory system. Which TWO statements accurately describe a relational database? (Choose two.)

Accepted Answer

Data is organized into tables with rows and columns.. A relational database organizes data into tables of rows and columns and links those tables through primary and foreign keys. Those two properties define the model. Storing each table on separate hardware, using unlabeled flat files, or requiring JavaScript for queries are all inconsistent with how relational databases actually work.

Answer

Each table must be stored on a separate physical server.

Answer

Records are stored as unlabeled values in a single flat file.

Answer

Queries are written only in JavaScript.

Question 8

A user reports that a database-backed inventory application is extremely slow when generating monthly reports, but normal data entry remains responsive. The technician observes that the report queries scan entire tables and that adding an index on the date column dramatically reduces report time. Which software concept explains why the index improved performance?

Accepted Answer

The index provides a faster lookup path so the database can locate matching rows without scanning every record. An index is an auxiliary structure that lets the database engine seek to matching rows rather than reading the whole table. When report queries filter on a date column, an index on that column converts a full scan into a targeted lookup, which explains the large speedup. Data entry stayed responsive because it operates on individual rows and does not depend on scanning the entire table.

Answer

The index rewrites the report query into a simpler form that the database executes more efficiently

Answer

The index caches the report results so subsequent runs return the same data instantly

Answer

The index compresses the table so it occupies less disk space during report generation

Question 9

A small business wants employees to use a cloud-based office suite so that multiple people can edit the same document at the same time and see each other's changes immediately. Which characteristic of the cloud-based suite makes this possible?

Accepted Answer

The suite stores documents on a central server and supports real-time co-authoring.. Real-time collaboration in a cloud-based office suite depends on central document storage plus continuous synchronization between participants. That combination lets several employees edit one shared document and see each other's changes as they happen. Local installation, email handoffs, and manual saving do not provide that simultaneous shared editing experience.

Answer

The suite is installed locally on each employee's computer.

Answer

The suite saves the document only when the user manually clicks Save.

Answer

The suite requires each employee to email the document to the next editor.

Question 10

A developer is writing a program that must handle multiple tasks simultaneously, such as downloading files while updating a user interface. Which programming concept allows the program to execute multiple sequences of instructions concurrently?

Accepted Answer

Multithreading. Multithreading allows a single program to execute multiple threads simultaneously, each performing a different task. This is ideal for scenarios like downloading files in the background while keeping the user interface responsive. Other concepts like recursion, OOP, or event-driven programming do not inherently provide concurrent execution of multiple instruction sequences.

Answer

Recursion

Answer

Event-driven programming

Answer

Object-oriented programming

Question 11

A user installs an open-source image editor on a personal laptop. The software is distributed with source code, and the user is allowed to modify and redistribute it under the same license terms. Which licensing characteristic best describes this software?

Accepted Answer

Open-source license permitting modification and redistribution under the same terms. Providing source code together with permission to modify and redistribute under the same license terms is the hallmark of an open-source license, particularly a copyleft one. Proprietary, freeware, and shareware models all restrict modification, redistribution, or both, and none of them align with the rights described. The defining factor is the granted freedom to use, study, change, and share the software.

Answer

Proprietary license with per-seat activation

Answer

Shareware license with a trial period before purchase

Answer

Freeware license that permits unlimited personal use

Question 12

A user is choosing a backup strategy for a laptop that contains important documents. The user wants copies of files stored in a second location and wants to be able to restore an earlier version of a file that was accidentally modified. Which TWO actions should the user perform? (Choose two.)

Accepted Answer

Copy important files to an external USB drive regularly.. A sound backup strategy needs both a second copy in a different location and the ability to recover earlier file versions. Copying to an external USB drive provides redundancy, while File History automatically maintains versioned backups on a separate drive. Maintenance tasks such as Disk Cleanup and defragmentation do not create backups, and a ZIP archive on the same drive offers neither off-device protection nor version history.

Answer

Run Disk Cleanup to remove temporary files from the system drive.

Answer

Defragment the hard drive to improve file access speed.

Answer

Create a compressed ZIP archive of the files on the same drive.

Question 13

A user receives a file with the extension .exe from an unknown sender. Before running it, the user wants to verify whether the file is safe. Which action best helps the user evaluate the risk?

Accepted Answer

Scan the file with updated antivirus software and check its reputation before running it.. The safest way to evaluate an unexpected executable is to scan it with updated antivirus protection and review its reputation or digital signature before running it. Opening, renaming, or forwarding the file either executes it, fails to neutralize it, or spreads the danger. Scanning and reputation checks provide evidence the user can act on.

Answer

Forward the file to coworkers so they can test it first.

Answer

Rename the file to .txt and then run it.

Answer

Open the file immediately to see what it does.

Question 14

A user is preparing a budget spreadsheet and wants to apply the same currency format, bold header row, and column widths to twelve monthly sheets inside one workbook. The user wants each sheet to update automatically if the header text changes. Which feature should the user apply?

Accepted Answer

A group of sheets selected together so edits apply to all at once. The goal is to make identical formatting and header edits across many sheets in one action. Selecting multiple worksheets into a group causes formatting, typing, and column-width changes to be applied to every sheet in the group at once. Macros replay actions without linking content, cell styles affect only appearance, and pivot tables analyze rather than format, so grouping is the only option that meets all stated needs.

Answer

A cell style applied individually to each sheet's header row

Answer

A macro that records the formatting steps and replays them on each sheet

Answer

A pivot table built from a consolidated range of all twelve sheets

Question 15

A technician is preparing a Windows workstation for a user who needs to run a legacy line-of-business program that requires specific runtime libraries and direct access to a hardware security key. The technician must choose installation and configuration steps that support these requirements. Which TWO actions are appropriate? (Choose two.)

Accepted Answer

Install the required runtime libraries before launching the legacy application.. The legacy program requires specific runtime libraries and access to a hardware security key. Installing the runtime libraries first ensures the application can load, and installing the key's driver and middleware enables the application to communicate with the hardware. Compatibility mode, disabling User Account Control, and changing the file system do not meet those two specific requirements.

Answer

Configure the application to run in compatibility mode for an older version of Windows.

Answer

Convert the system drive to a different file system before installing the application.

Answer

Disable User Account Control for all users on the workstation.
