FC0-U71 Practice Test 38 — 15 Questions

Question 1

A security analyst is reviewing user permissions and discovers that several users have been granted more privileges than necessary to perform their job functions. The analyst wants to apply the principle of least privilege. Which TWO actions should the analyst take? (Choose TWO.)

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

Accepted Answer

Audit current permissions to identify unnecessary privileges. Auditing current permissions (Option B) is the first step in applying least privilege because it identifies exactly which users have excessive rights. Creating RBAC groups (Option C) then allows the analyst to assign permissions based on job functions, ensuring users only have the access necessary to perform their roles. Together, these actions systematically reduce privilege levels without disrupting operations.

Answer

Grant full administrative access to a single IT administrator

Answer

Allow users to request temporary elevation of privileges for specific tasks

Answer

Remove all permissions from users and add them back only when requested

Question 2

A home user wants to connect a desktop computer to the internet using a wireless connection. The computer does not have built-in Wi-Fi. What is the simplest and most cost-effective solution? The user has a wireless router already installed and working.

Accepted Answer

Install a wireless network adapter (USB or PCIe). A wireless network adapter (USB or PCIe) adds Wi-Fi capability to a desktop that lacks it, directly connecting to the existing wireless router. This is the simplest and most cost-effective solution because it requires no new infrastructure or cabling, and USB adapters are plug-and-play with minimal setup.

Answer

Use a powerline adapter to extend the network

Answer

Replace the computer with a laptop that has Wi-Fi

Answer

Run an Ethernet cable from the router to the computer

Question 3

A user reports that their computer is running slowly and the hard drive activity light is constantly on. The technician checks Task Manager and sees that disk usage is at 100%. What is the most likely cause?

Accepted Answer

Insufficient RAM causing the system to use the hard drive as virtual memory excessively. When RAM is insufficient, the operating system compensates by using a portion of the hard drive as virtual memory (the page file). This causes constant swapping of data between RAM and the disk, resulting in 100% disk usage and a continuously active hard drive light. Task Manager would show high disk usage even if the CPU and memory percentages appear moderate.

Answer

Malware infection that is encrypting files in the background

Answer

A failing hard drive that needs to be replaced immediately

Answer

The hard drive is almost full and needs to be defragmented

Question 4

Which TWO of the following are common characteristics of compiled programming languages?

Accepted Answer

The resulting executable is platform-specific.. Compiled languages produce machine code that is specific to the target operating system and processor architecture. This platform-specific executable cannot run on a different OS or CPU without recompilation, which is a defining characteristic of compiled languages like C or C++.

Answer

The code is executed line-by-line by an interpreter.

Answer

Variables do not need to be declared before use.

Answer

The source code is compiled every time the program runs.

Question 5

A technician is troubleshooting a computer that will not power on. Which of the following should be checked FIRST?

Accepted Answer

Whether the power cable is plugged in. The most fundamental requirement for a computer to power on is a stable electrical connection. Checking whether the power cable is plugged in is the first step in the troubleshooting methodology because it eliminates the simplest and most common cause of a no-power condition before moving to more complex diagnostics. Without verifying the power source, any other troubleshooting is premature.

Answer

The network connection

Answer

The operating system version

Answer

The amount of free disk space

Question 6

Which TWO of the following are examples of operating systems?

Accepted Answer

Windows 10. Windows 10 is a graphical operating system developed by Microsoft that manages hardware resources, runs applications, and provides a user interface. It is classified as an operating system because it handles process scheduling, memory management, and device I/O operations, which are core OS functions.

Answer

Adobe Photoshop

Answer

Google Chrome

Answer

Microsoft Office

Question 7

A program crashes with a 'division by zero' error. Which of the following is the most likely cause?

Accepted Answer

An unvalidated user input that results in a zero divisor. A 'division by zero' error occurs when a program attempts to divide a number by zero, which is mathematically undefined and typically raises a runtime exception. The most likely cause is unvalidated user input that supplies a zero as the divisor, because the program does not check or sanitize the input before performing the arithmetic operation.

Answer

A misspelled variable name

Answer

An infinite loop

Answer

An array index out of bounds

Question 8

A developer sees the above error message. What type of error is this?

Accepted Answer

Runtime error. D is correct because a runtime error occurs when a program is executing and encounters an unexpected condition, such as division by zero, null pointer dereference, or an unhandled exception. The error message shown (not provided here but implied) typically appears during program execution, not during compilation or syntax checking. Runtime errors are distinct from compile-time errors because they only manifest when the code is actually running.

Answer

Syntax error

Answer

Compile error

Answer

Logic error

Question 9

Which network topology connects all devices to a single central cable?

Accepted Answer

Bus. A bus topology uses a single central cable, often called a backbone or trunk, to which all devices are connected via drop lines or taps. Data transmitted by any device travels along the entire cable, and each device checks the destination address to determine if it should accept the data. This contrasts with other topologies that use different physical or logical connection methods.

Answer

Ring

Answer

Star

Answer

Mesh

Question 10

A company is choosing collaboration software. Which TWO of the following are examples of collaboration applications? (Select 2)

Accepted Answer

Microsoft Teams. Slack and Microsoft Teams are collaboration tools for communication and teamwork.

Answer

Microsoft Excel

Answer

Google Chrome

Answer

Adobe Photoshop

Question 11

Match each network type to its description.

Accepted Answer

LAN: Local Area Network. Network types are classified by geographic scope: LAN (local), WAN (wide), MAN (metropolitan), PAN (personal). Common confusions involve swapping LAN and WAN definitions.

Answer

LAN: Wide Area Network

Answer

WAN: Local Area Network

Question 12

Which THREE of the following are common phases in the software development life cycle (SDLC)?

Accepted Answer

Requirements gathering. Requirements gathering is the foundational phase in the SDLC where stakeholders and developers define what the software must accomplish. This phase produces a Software Requirements Specification (SRS) document that guides all subsequent phases. Without accurate requirements, the entire project risks building the wrong product, leading to costly rework.

Answer

Release

Answer

Coding

Question 13

A team of developers is collaborating on a mobile app using Git. One developer, Alice, is working on a new feature in a branch called "new-feature". Bob, another developer, has pushed several bug fixes to the main branch. Alice now wants to incorporate Bob's bug fixes into her feature branch. Which sequence of Git commands should Alice use to achieve this with minimal disruption?

Accepted Answer

git checkout new-feature, git merge main, then resolve conflicts if any.. Merging the main branch into the feature branch (git checkout new-feature, git merge main) brings the fixes into Alice's branch. The opposite (merging feature into main) would add unfinished work to main. Rebasing with force push is dangerous. Creating a new branch doesn't bring in fixes.

Answer

git fetch, git rebase new-feature onto origin/main, then force push.

Answer

git checkout -b new-feature, git push.

Answer

git checkout main, git pull, git merge new-feature, then push.

Question 14

Accepted Answer

Customer collaboration. Customer collaboration is a core value of the Agile Manifesto, which prioritizes direct, ongoing communication with the customer over rigid contract negotiation. This ensures the development team can adapt to evolving requirements and deliver software that truly meets the customer's needs, rather than just following a predefined specification.

Answer

Strict adherence to a fixed plan

Answer

Emphasis on documentation over working software
