FC0-U71 Practice Test 39 — 15 Questions

Question 1

A technician is cleaning up a Windows workstation that has accumulated many installed programs. The technician wants to remove applications that were installed as part of a bundled package and also wants to free disk space consumed by leftover installation files. Which TWO actions should the technician perform? (Choose two.)

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

Accepted Answer

Run Disk Cleanup and select the temporary files and Windows Update cleanup categories. Removing bundled applications requires invoking each program's registered uninstaller, which is exposed through Programs and Features, so that associated files and registry entries are removed together. Reclaiming space from leftover installation files is a separate task handled by Disk Cleanup categories such as temporary files and Windows Update cleanup. Manually deleting Program Files, disabling the installer service, or relocating the pagefile do not accomplish either goal.

Answer

Disable the Windows Installer service in Services.msc

Answer

Delete the contents of the Program Files directory

Answer

Move the pagefile to a different drive

Question 2

A junior developer is tasked with fixing a bug where a variable is unexpectedly undefined. The developer suspects the variable is not within scope. Which programming concept describes where a variable can be accessed?

Accepted Answer

Scope. Scope is the programming concept that defines the region of code where a variable is accessible. If a variable is unexpectedly undefined, it is often because it was declared outside the current block or function, making it out of scope. In JavaScript, for example, variables declared with `let` or `const` inside a block are not accessible outside that block.

Answer

Loop

Answer

Data type

Answer

Function

Question 3

A user has just installed a new word-processing application on their laptop. When the user tries to open the application for the first time, a window appears asking for a product key. The user purchased the software online and received an email with the product key. Where should the user enter the product key to activate the software?

Accepted Answer

Enter the product key into the activation window that appeared.. The activation window that appears when launching the application is the standard interface for entering a product key. This window is generated by the application itself, not the operating system, and is the intended mechanism to validate the license before full functionality is granted.

Answer

Look for the product key field in the application's 'File' menu.

Answer

Open the operating system's settings and navigate to 'Activation'.

Answer

Close the activation window and try to use the software without activation.

Question 4

A company is deploying software to multiple workstations without user interaction. Which TWO installation methods are considered silent installations?

Accepted Answer

Running setup.exe /quiet. Option B is correct because running setup.exe /quiet invokes the installer's silent mode, suppressing the user interface and requiring no interaction, which is exactly what unattended deployment needs. Option C is correct because msiexec /i package.msi /qn installs the MSI package with the /qn switch, which sets the Windows Installer UI level to "no UI," producing a fully silent installation. Option A is not silent since double-clicking setup.exe and clicking Next requires manual user input at each wizard step. Option D is not a silent installation method because app store installations typically involve user-driven prompts and account interaction. Option E is not silent because downloading from a website and manually running the installer requires user action to initiate and complete the install.

Answer

Double-clicking setup.exe and clicking Next each time

Answer

Using an app store to install

Answer

Downloading from a website and manually running the installer

Question 5

An IT instructor is teaching about binary arithmetic operations. Which TWO of the following are correct results of a logical XOR operation on the binary inputs 1 and 0? (Select TWO.)

Accepted Answer

0 XOR 1 = 1. XOR outputs 1 whenever the two input bits differ, and here 0 and 1 are different. Option D (1 XOR 0 = 1) is also correct for the same reason: the inputs 1 and 0 are unequal, so the XOR result is 1. The unmarked options do not belong: A (1 XOR 0 = 0) and E (0 XOR 1 = 0) incorrectly claim a 0 result for differing inputs, while C (1 XOR 1 = 1) incorrectly claims a 1 result for equal inputs, since XOR of identical bits is always 0.

Answer

1 XOR 0 = 0

Answer

1 XOR 1 = 1

Answer

0 XOR 1 = 0

Question 6

You are an IT support specialist for a mid-sized company. A user in the accounting department, Jane, reports that her accounting software (QuickBooks 2021) crashes every time she tries to export a report to PDF. The crash occurs immediately after clicking 'Export to PDF' and displays the error: 'The application has stopped working.' Jane's workstation runs Windows 10 Pro with 8GB RAM and an SSD. She has sufficient disk space. Other users in the same department using the same software version do not experience this issue. Jane recently installed a free PDF printer driver for personal use. What is the most likely cause and the best course of action?

Accepted Answer

Remove the recently installed PDF printer driver and test the export again.. The most likely cause is the recently installed free PDF printer driver, which conflicts with QuickBooks' PDF export functionality. QuickBooks relies on its own PDF generation engine or system PDF printers, and a third-party PDF driver can intercept or corrupt the export process, causing the crash. Removing the driver and testing is the best first step because it isolates the change without affecting other software or system files.

Answer

Reinstall QuickBooks 2021 using the original installation media.

Answer

Reinstall Windows 10 because the operating system is corrupted.

Answer

Update all printer drivers to the latest versions.

Question 7

A small e-commerce company uses a monolithic web application hosted on a single server. During peak shopping hours, the server becomes overloaded, causing slow page loads and occasional timeouts. The development team wants to improve scalability and maintainability. They are considering breaking the application into smaller, independent services that can be developed, deployed, and scaled separately. Which approach should the team adopt?

Accepted Answer

Migrate to a microservices architecture.. Microservices architecture decomposes a monolithic application into small, independently deployable services, each owning its own data and scaling independently. This directly addresses the stated goals: improve scalability (scale only the hot services) and maintainability (smaller, focused codebases with independent deployment cycles). The scenario explicitly describes breaking the app into smaller, independent services.

Answer

Move the application to a serverless computing platform.

Answer

Implement a service-oriented architecture (SOA) with an enterprise service bus.

Answer

Containerize the existing monolithic application.

Question 8

Which of the following is a valid SQL statement to retrieve all records from a table named 'Employees'?

Accepted Answer

SELECT * FROM Employees. The correct SQL statement to retrieve all records from a table named 'Employees' is SELECT * FROM Employees. The SELECT clause specifies the columns to return, and the asterisk (*) is a wildcard meaning all columns. The FROM clause specifies the table to query. This is standard SQL syntax defined by ANSI/ISO and supported by all major relational database management systems (RDBMS) such as MySQL, PostgreSQL, SQL Server, and Oracle.

Answer

GET * FROM Employees

Answer

FETCH * FROM Employees

Answer

READ * FROM Employees

Question 9

A user reports that when they try to open a PDF file attached to an email, nothing happens. Which of the following is the most likely cause?

Accepted Answer

There is no software installed that can open PDF files.. If no software is installed that can handle PDF files, the operating system has no default handler to open the file. When a user clicks on a PDF attachment in an email client, the system attempts to launch the associated application (e.g., Adobe Acrobat Reader, a web browser with PDF support). If no such application is present, nothing happens—the file simply does not open, and no error message may appear depending on the email client's configuration.

Answer

The file permissions are set to read-only.

Answer

The antivirus software has quarantined the file.

Answer

The network connection is down.

Question 10

Which THREE of the following are examples of multi-factor authentication? (Select three.)

Accepted Answer

A smart card and a PIN. Multi-factor authentication (MFA) requires combining factors from different categories: something you know (password, PIN), something you have (smart card, phone, token), and something you are (biometrics such as fingerprint or retina scan). Option A is correct because a smart card (something you have) plus a PIN (something you know) combines two distinct factor types. Option B is correct because a password (something you know) plus a fingerprint scan (something you are) also mixes two different factor categories. Option E is correct because a one-time code sent to a phone (something you have) plus a password (something you know) likewise draws on two separate factor types. Option C does not qualify because a retina scan and a fingerprint scan are both biometrics, i.e., two instances of the same 'something you are' factor. Option D does not qualify because a username and password are both 'something you know' and represent a single authentication factor.

Answer

A retina scan and a fingerprint scan

Answer

A username and password

Question 11

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 12

A company implements a policy requiring employees to use a password and a one-time code sent to their mobile phone when logging into the corporate network. Which security concept is being employed?

Accepted Answer

Multi-factor authentication. Multi-factor authentication (MFA) requires two or more verification factors to gain access, such as a password (something you know) and a one-time code sent to a mobile phone (something you have). This combination enhances security by adding a layer beyond just a password.

Answer

Role-based access control

Answer

Single sign-on

Answer

Biometrics

Question 13

A technician is setting up a small office network. Which device should be used to connect multiple computers and allow them to communicate with each other?

Accepted Answer

Switch. A switch operates at Layer 2 of the OSI model and uses MAC addresses to forward frames only to the specific port where the destination device is connected. This allows multiple computers on the same local network to communicate directly with each other without unnecessary traffic, making it the correct device for interconnecting computers in a small office LAN.

Answer

Router

Answer

Modem

Answer

Hub

Question 14

A software development team is using Scrum. During a sprint, the product owner introduces a new high-priority requirement that was not in the sprint backlog. The team has already committed to the current sprint's goals. According to Scrum principles, what should the team do?

Accepted Answer

Include the new requirement in the next sprint planning. In Scrum, the sprint backlog is frozen once the sprint starts; new requirements should be added to the product backlog for future sprints.

Answer

Ask the development team to work overtime to accommodate the new requirement

Answer

Hold an emergency sprint planning meeting to adjust the sprint backlog

Answer

Add the new requirement to the current sprint and remove a lower-priority item

Question 15

A company wants to prevent unauthorized physical access to its server room. Which control is best?

Accepted Answer

Biometric lock. A biometric lock is the best control for preventing unauthorized physical access to a server room because it authenticates individuals based on unique physiological traits (e.g., fingerprint, iris scan), directly securing the physical entry point. Unlike logical or data-level controls, it addresses the physical security domain by restricting who can enter the room, not what data they can access.

Answer

Firewall

Answer

Antivirus

Answer

Encryption
