FC0-U71 Practice Exam 58 — 20 Questions

Question 1

A user reports that a desktop application crashes every time it tries to save a file to a network drive. Other applications work fine. Which is the MOST likely cause?

Accepted Answer

Insufficient permissions on the network share. The most likely cause is insufficient permissions on the network share (D). When a desktop application crashes specifically during a save operation to a network drive, but other applications work fine, it often indicates that the application lacks the necessary write permissions to the target folder or file. This can trigger an unhandled exception in the application's save routine, leading to a crash, whereas other applications may handle the permission denial gracefully or use different access methods.

Answer

Outdated network driver

Answer

Insufficient local disk space

Answer

Corrupted application installation

Question 2

A team is using version control for a software project. A developer accidentally committed a buggy change to the main branch. Which action should the team take to fix this while preserving the commit history?

Accepted Answer

Use the revert command to create a new commit that undoes the changes.. The `git revert` command creates a new commit that undoes the changes introduced by a previous commit, effectively fixing the buggy code while preserving the full commit history. This is the standard, safe approach in Git for undoing changes on a shared branch like main, as it does not rewrite history or require force-pushing.

Answer

Ask all developers to manually undo the changes in their local copies.

Answer

Delete the repository and start over.

Answer

Force delete the commit from history.

Question 3

A small business wants to use a CRM system. They need to access it from mobile devices and desktops without installing software. Which deployment model fits?

Accepted Answer

Software as a Service (SaaS). Software as a Service (SaaS) delivers the CRM application over the internet, allowing users to access it from any device with a web browser without installing software. This model matches the requirement for mobile and desktop access with zero local installation, as the provider hosts and manages the entire application stack.

Answer

Platform as a Service (PaaS)

Answer

On-premises

Answer

Infrastructure as a Service (IaaS)

Question 4

An office manager needs to replace a printer that will primarily print text documents and has a high monthly page volume. Which type of printer would be MOST cost-effective?

Accepted Answer

Question 5

A company wants to store product catalogs that vary in structure (different attributes per product). Which type of database is best suited?

Accepted Answer

Document database. A document database (NoSQL) is ideal for storing product catalogs with varying structures because it stores data in flexible, schema-less documents (e.g., JSON or BSON). Each product can have different attributes without requiring predefined columns or schema migrations, unlike relational databases. This allows the company to handle heterogeneous product data efficiently.

Answer

Relational database

Answer

Network database

Answer

Hierarchical database

Question 6

Which TWO of the following are types of software licenses? (Select TWO).

Accepted Answer

Proprietary. Proprietary software licenses grant the creator exclusive rights to the software, typically restricting modification, redistribution, and access to the source code. This is the standard model for commercial software like Microsoft Windows or Adobe Photoshop, where users purchase a license to use the software but do not own it.

Answer

Router

Answer

Switch

Answer

Firewall

Question 7

You are the IT administrator for a small company with 50 employees. The company uses a shared network drive for project files. Employees have read/write access to all folders on the drive. Recently, a ransomware attack encrypted many files on the network drive after an employee's workstation became infected. The employee had mapped the drive as a local letter. Backups are available but restoring takes several hours. Management wants to reduce the risk of future ransomware damage to the network drive. You are considering implementing one of the following controls. Which control would be most effective in limiting the spread of ransomware to the network drive?

Accepted Answer

Implement file-level permissions so users only have write access to folders they need.. Implementing file-level permissions with the principle of least privilege restricts users to only write access to folders they need. This limits the number of files a ransomware infection can encrypt, reducing potential damage. Option A is incorrect because disk encryption protects data at rest but does not prevent ransomware from encrypting files. Option C is incorrect because antivirus software may not detect or stop new ransomware variants. Option D is incorrect because a VPN secures remote access but does not protect against internal threats like ransomware.

Answer

Enable disk encryption on the network drive.

Answer

Install antivirus software on all workstations and schedule weekly scans.

Answer

Require all employees to use a VPN when accessing the network drive.

Question 8

An IT administrator applies the software restriction policy shown in the exhibit. What is the intended effect of this policy?

Accepted Answer

Allows executables in Program Files to run, but blocks others.. The software restriction policy shown in the exhibit uses a 'Disallowed' default rule, which blocks all executables by default. It then creates an 'Unrestricted' path rule for `%ProgramFiles%`, which explicitly allows executables in that folder to run. Therefore, executables in Program Files are allowed, while all others (e.g., in Temp, AppData, or Downloads) are blocked.

Answer

Allows executables in the Temp folder to run.

Answer

Blocks executables in Program Files but allows in AppData.

Answer

Blocks all executables on the system.

Question 9

A technician is explaining the difference between volatile and non-volatile memory. Which of the following is an example of volatile memory?

Accepted Answer

RAM. RAM (Random Access Memory) is volatile memory because it requires continuous electrical power to retain data; once the system is powered off, all data stored in RAM is lost. This is in contrast to non-volatile memory, which retains data without power. The question specifically asks for an example of volatile memory, and RAM is the classic example.

Answer

Hard disk drive

Answer

Solid-state drive

Answer

USB flash drive

Question 10

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 11

The correct order to create a new folder on the desktop in Windows 10 is: right-click on an empty area of the desktop, select New from the context menu, then select Folder from the submenu, and finally type a name for the folder and press Enter. This sequence ensures the folder is created before naming it.

Answer

Left-click desktop -> New -> Folder -> Type name and press Enter

Answer

Right-click desktop -> Folder -> New -> Type name and press Enter

Answer

Right-click desktop -> New -> Type name -> Folder

Question 13

A database table contains redundant employee data, leading to update anomalies. Which database design process should be applied to resolve this?

Accepted Answer

Normalization. Normalization is the database design process that eliminates redundant data and ensures data dependencies make sense, thereby resolving update anomalies. By decomposing a table into smaller, related tables and defining relationships through foreign keys, normalization reduces data duplication and maintains consistency during insert, update, and delete operations.

Answer

Indexing

Answer

Denormalization

Answer

Query optimization

Question 14

Which of the following cloud service models is correctly paired with its description?

Accepted Answer

IaaS: Provides virtualized computing resources over the internet. Ly identifies that IaaS provides virtualized computing resources over the internet. Options B and E are incorrect because PaaS provides a platform for application development, not software applications or virtualized resources. Options C and D are incorrect because SaaS delivers software applications, and IaaS does not provide a platform for development.

Answer

PaaS: Provides software applications over the internet

Answer

SaaS: Provides platform and environment for developers to build apps

Answer

IaaS: Provides platform for application development and deployment

Answer

PaaS: Provides virtualized computing resources such as VMs and storage

Question 15

A database includes a table called 'Products' with columns: ProductID, ProductName, Price, and Quantity. Which TWO of the following SQL statements correctly insert a new product into the table? (Select TWO.)

Accepted Answer

INSERT INTO Products (ProductID, ProductName, Price, Quantity) VALUES (1, 'Widget', 9.99, 100). Only the INSERT statements that provide values for all required columns in the correct order are valid. Option C explicitly lists columns and provides correct values. Option E omits column names but provides values for all four columns in the correct order. Option A uses an invalid syntax (SET clause is not standard SQL for INSERT). Option B provides three values but only two column names, causing a mismatch. Option D provides only three values for a four-column table.

Answer

INSERT INTO Products SET ProductID=1, ProductName='Widget'

Answer

INSERT INTO Products (ProductName, Price) VALUES ('Widget', 9.99, 100)

Answer

INSERT INTO Products VALUES (1, 'Widget', 9.99)

Question 16

A developer writes the following pseudocode: for i = 1 to 5, sum = sum + i. What does this code do?

Accepted Answer

It sums the numbers from 1 to 5. The pseudocode initializes a loop that iterates with i taking values 1, 2, 3, 4, and 5. In each iteration, the current value of i is added to the variable sum. After the loop completes, sum holds the total of 1+2+3+4+5, which is 15. This is a standard accumulator pattern used in programming to compute a running total.

Answer

It adds 5 to the sum

Answer

It multiplies numbers from 1 to 5

Answer

It prints the numbers from 1 to 5

Question 17

Which THREE are phases of the software development life cycle? (Choose three.)

Accepted Answer

Planning. The software development life cycle (SDLC) consists of distinct phases that guide the creation of software from initial concept to final deployment and maintenance. Planning is the foundational phase where project goals, scope, resources, and risks are identified, making it a core SDLC phase. Deployment and Coding are also standard phases, with Coding being the phase where source code is written and Deployment being the phase where the finished software is released to production.

Answer

Marketing

Answer

Debugging

Question 18

A user reports that their laptop cannot connect to the corporate Wi-Fi. Other devices are working fine. Which TWO troubleshooting steps should the technician take first? (Choose TWO.)

Accepted Answer

Verify the SSID and password on the laptop.. Verifying the SSID and password is the most basic and common cause of a single device failing to connect to Wi-Fi. If other devices are working, the issue is isolated to the laptop, so checking its wireless configuration is a logical first step. This aligns with the 'isolate the problem' troubleshooting methodology.

Answer

Check the DHCP server for available IP addresses.

Answer

Update the network adapter driver.

Answer

Restart the wireless router.

Question 19

A developer writes a script to calculate the average of a list of numbers. The script uses a loop to sum the numbers and then divides by the count. Which programming concept does this represent?

Accepted Answer

Iteration. The script uses a loop to repeatedly access each number in the list and add it to a running total. This repeated execution of a block of code (the loop body) is the defining characteristic of iteration. Iteration is the correct programming concept because the average calculation depends on cycling through a sequence of elements, which is exactly what a loop provides.

Answer

Selection

Answer

Recursion

Answer

Sequence

Question 20

What is the most likely reason PC1 cannot ping PC2?

Accepted Answer

A firewall on PC2 is blocking ICMP echo requests. A firewall on PC2 can be configured to block ICMP echo requests (ping) while allowing other traffic. Option A is incorrect because the default gateway is only needed for communication outside the subnet; PC1 and PC2 are on the same subnet. Option C is incorrect because if PC2's network interface were disabled, PC1 would be unable to communicate with PC2 for any service, not just ping. Option D is incorrect because a faulty switch port would cause complete loss of connectivity for PC2, not just ping failures.

Answer

The default gateway is incorrect on PC1

Answer

PC2's network interface is disabled

Answer

The switch port for PC2 is faulty
