FC0-U71 Practice Test 11 — 15 Questions

Question 1

Which of the following best describes the function of an operating system?

Accepted Answer

Controls hardware and provides a user interface. The operating system (OS) is system software that manages computer hardware, software resources, and provides common services for computer programs. Its core functions include process management, memory management, device management, and providing a user interface (such as a command-line interface or graphical user interface) for interaction. Without an OS, a user cannot directly control hardware or run application software.

Answer

Encrypts all data on the computer

Answer

Manages only file storage

Answer

Provides internet connectivity

Question 2

Accepted Answer

Tailgating. Tailgating occurs when an unauthorized person follows an authorized person into a restricted area. Option A is wrong because shoulder surfing involves looking at someone's screen or keystrokes. Option B is wrong because phishing is a deceptive message or email. Option D is wrong because malware is malicious software.

Answer

Shoulder surfing

Answer

Phishing

Answer

Malware

Question 3

Refer to the exhibit. Which of the following components would be used to physically connect the desktop computer to the network?

Accepted Answer

Switch. A switch is the correct component because it operates at Layer 2 of the OSI model, using MAC addresses to forward frames between devices on the same local area network (LAN). The desktop computer's Ethernet NIC connects via a twisted-pair cable to a switch port, which provides the physical and data-link layer connectivity required for network communication.

Answer

Laptop

Answer

Network printer

Answer

Router

Question 4

Which TWO of the following are common types of network cables used in wired Ethernet networks?

Accepted Answer

Cat5e. Cat5e (Category 5 enhanced) is a twisted-pair copper cable standard that supports Gigabit Ethernet (1000BASE-T) up to 100 meters. It is one of the most common cable types for wired Ethernet networks because it provides sufficient bandwidth (up to 1000 Mbps) and is backward compatible with older 10/100 Mbps standards.

Answer

HDMI

Answer

Coaxial

Answer

USB

Question 5

Which TWO of the following are examples of security software? (Choose TWO.)

Answer

Media player

Answer

Web browser

Answer

Text editor

Question 6

A programmer writes code to run a block of instructions repeatedly until a condition is met. Which programming concept is being used?

Accepted Answer

Loop. A loop (for, while) repeats code. Functions are reusable blocks, conditionals make decisions, variables store data.

Answer

Conditional

Answer

Function

Answer

Variable

Question 7

A company uses a software license that allows anyone to view, modify, and distribute the source code, provided that any distributed modifications are also made available under the same license. Which type of license is this?

Accepted Answer

GNU General Public License (GPL). This describes a copyleft open-source license, such as the GNU General Public License (GPL), which requires derivative works to be distributed under the same license.

Answer

MIT License

Answer

Freeware

Answer

Shareware

Question 8

A company uses a web-based application that runs in a browser and stores data on a remote server. Which of the following best describes this type of application?

Accepted Answer

Web application. Web applications are accessed via a browser and have server-side processing and storage. Desktop applications are installed locally, mobile apps run on mobile devices, and hybrid apps combine web and native elements but are not purely browser-based.

Answer

Desktop application

Answer

Mobile app

Answer

Hybrid app

Question 9

A company is evaluating different software licenses for a new project. Which THREE of the following are characteristics of open-source licenses such as the MIT License or Apache License? (Select THREE.)

Accepted Answer

Users can modify the source code.. Open-source licenses grant users the freedom to use, modify, and distribute the software. The MIT and Apache licenses are permissive, meaning they allow proprietary derivative works (no copyleft requirement). They do not require payment.

Answer

Users must keep their modifications private.

Answer

Users must pay a fee to use the software.

Question 10

Which of the following best describes the function of a web API?

Accepted Answer

It allows different software applications to communicate and exchange data.. A web API (Application Programming Interface) allows different software applications to communicate and share data over the internet. It is not a user interface, security tool, or database language.

Answer

It encrypts data transmitted between a web browser and server.

Answer

It is a programming language used to query databases.

Answer

It provides a graphical user interface for web applications.

Question 11

A web developer wants to identify why a web page is loading slowly. Which built-in browser tool is most appropriate to analyze network requests?

Accepted Answer

Developer Tools. Developer Tools (F12) include a Network tab that captures all HTTP/HTTPS requests made by the page, showing timing details (DNS lookup, TCP handshake, TLS negotiation, time to first byte, content download) and response sizes. This allows the developer to pinpoint slow resources, such as large images, unoptimized scripts, or server delays, making it the correct tool for analyzing network performance.

Answer

Password manager

Answer

Download manager

Answer

Bookmark manager

Question 12

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. Merging combines changes from one branch into another. Committing saves changes locally, branching creates a new line of development, cloning copies a repository.

Answer

Branch

Answer

Commit

Answer

Clone

Question 13

Which of the following is a key difference between a web application and a desktop application?

Accepted Answer

Web applications run inside a browser and process data on a server; desktop applications run directly on the OS and have direct hardware access.. Web applications run in a browser and rely on server-side processing, while desktop applications are installed locally and can directly access hardware resources.

Answer

Desktop applications are stored on a remote server; web applications are installed locally.

Answer

Web applications require an internet connection to run; desktop applications do not.

Answer

Desktop applications require a subscription; web applications are free.

Question 14

A company needs to store customer orders, where each order can contain multiple items. Which database design is most appropriate?

Accepted Answer

Two tables: Orders and OrderItems, linked by an OrderID foreign key.. It uses a normalized relational design with two tables: Orders (holding order-level data) and OrderItems (holding individual item details per order). The OrderID foreign key in OrderItems creates a one-to-many relationship, allowing each order to contain multiple items without data redundancy or update anomalies. This design ensures referential integrity and efficient querying, which is the standard approach for transactional order systems.

Answer

Three tables: Orders, Customers, and Items, with no direct link.

Answer

A single table storing all data in a JSON column.

Answer

A single table with columns for order details and repeated item information.

Question 15

Which TWO concerns are most critical when selecting a backup method? (Select exactly two.)

Accepted Answer

Recovery time objective. Recovery time objective (RTO) is critical because it defines the maximum acceptable downtime after a failure, directly influencing the choice of backup method (e.g., full vs. incremental) and storage medium (e.g., local disk vs. cloud). A shorter RTO requires faster restoration, often necessitating more frequent backups or technologies like snapshots or replication.

Answer

Network topology

Answer

Display resolution

Answer

Operating system version
