FC0-U71 Practice Test 35 — 15 Questions

Question 1

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.. It accurately captures the architectural distinction: web applications execute within a browser's sandboxed environment and typically rely on remote servers for data processing and storage, while desktop applications are installed on the local machine, run natively on the operating system, and can directly access hardware resources like the file system, GPU, and peripherals. This difference in execution environment and resource access is the fundamental technical differentiator between the two application models.

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 2

Which TWO of the following are examples of NoSQL database types?

Accepted Answer

Document store. A document store (D) is a NoSQL database type that stores semi-structured data as JSON-like documents (e.g., MongoDB, CouchDB), allowing flexible, schema-less records. A key-value store (E) is also a NoSQL type that maps unique keys to values for fast lookups (e.g., Redis, DynamoDB), which is a core category of NoSQL databases. Spreadsheets (A) are productivity tools, not database types, and lack the querying and scaling characteristics of databases. A relational database (B) is the SQL model using tables, rows, and columns with fixed schemas, so it is not NoSQL. A flat file (C) is a simple file format for storing data, not a NoSQL database category.

Answer

Spreadsheet

Answer

Relational database

Answer

Flat file

Question 3

A web application needs to send user registration data to a server. Which HTTP method should be used?

Accepted Answer

POST. The POST method is designed to submit data to be processed to a specified resource, such as creating a new user registration record on a server. Unlike GET, which appends data to the URL, POST sends the registration data in the request body, making it suitable for non-idempotent operations where each submission creates a new resource or triggers server-side processing.

Answer

PUT

Answer

DELETE

Answer

GET

Question 4

A security guard notices an individual following closely behind an employee through a secured door without swiping a badge. This scenario is an example of which type of security threat?

Accepted Answer

Tailgating. Tailgating is the physical security breach where an unauthorized person follows an authorized individual through a secured entry point without presenting their own credentials. In this scenario, the individual closely follows an employee through a secured door without swiping a badge, which exactly matches the definition of tailgating. This threat exploits human politeness or inattention and does not require technical hacking.

Answer

Shoulder surfing

Answer

Phishing

Answer

Malware

Question 5

A company wants to protect its network from unauthorized external access. Which of the following devices should be configured to filter traffic based on port and protocol?

Accepted Answer

Network firewall. A network firewall is specifically designed to inspect and filter traffic traversing the network perimeter based on rules that match port numbers, protocols (TCP/UDP/ICMP), and source/destination IP addresses. It sits between the internal network and external networks, making it the correct device to block unauthorized external access at the network boundary.

Answer

Host-based firewall

Answer

VPN concentrator

Answer

Antivirus software

Question 6

Which of the following is the strongest password?

Accepted Answer

MyD0g!sF1d0. MyD0g!sF1d0 is the strongest because it is the longest option (11 characters) and combines uppercase, lowercase, digits, and special characters in a non-dictionary phrase. Length is the primary driver of password strength, and this password avoids common words or predictable substitutions like 'P@ssw0rd'. It would take significantly longer to crack via brute force or dictionary attacks than the other options.

Answer

12345678

Answer

P@ssw0rd

Answer

password

Question 7

A developer is writing a program that processes whole numbers only. Which data type should be used?

Accepted Answer

Integer. (Integer) because the program processes whole numbers only, and the integer data type is specifically designed to store non-fractional numeric values without decimal points. In most programming languages, integers are stored as 32-bit or 64-bit binary values, making them efficient for arithmetic operations on whole numbers.

Answer

Float

Answer

String

Answer

Boolean

Question 8

A developer is testing a piece of code that calculates discounts. The code should give 10% off for orders over $100, and 5% off for orders between $50 and $100. Which test input set would best verify boundary conditions?

Accepted Answer

$49.99, $50.00, $99.99, $100.00, $100.01. It tests the exact boundary values for the discount tiers: $49.99 (just below $50, no discount), $50.00 (5% threshold), $99.99 (still 5%), $100.00 (boundary between 5% and 10%), and $100.01 (10% threshold). This set validates both the lower and upper edges of each range, ensuring the code handles floating-point comparisons correctly.

Answer

$50, $100, $150

Answer

$0, $50, $100, $200

Answer

$50.00, $100.00

Question 9

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 10

Which TWO of the following are types of desktop applications?

Accepted Answer

Web browser. A web browser (D) is a classic desktop application because it is installed locally on a workstation's operating system (Windows, macOS, Linux) and runs as a native GUI process on that machine. A media player like VLC (E) is likewise a desktop application: it is installed locally and executes on the user's own computer to play audio/video files. By contrast, a mobile app from Google Play (A) is packaged for Android/iOS mobile platforms, not desktop operating systems. A server-side script (B) executes on a server (e.g., PHP, ASP.NET, Node.js) rather than on the user's desktop. A web-based email client (C) runs in the browser and is delivered from a remote web server, so it is a web application, not a desktop application.

Answer

Mobile app from Google Play

Answer

Server-side script

Answer

Web-based email client

Question 11

Refer to the exhibit. PC1 (192.168.1.10) cannot communicate with PC2 (192.168.2.10). What is the most likely cause?

Accepted Answer

Router1 lacks a route to the 192.168.2.0/24 network. Router1 lacks a route to the 192.168.2.0/24 network, so when PC1 sends traffic to PC2, Router1 does not have a destination network entry in its routing table to forward the packets. Without a route, the router drops the packets and may send an ICMP Destination Unreachable message back to PC1. This is the most likely cause because PC1 can reach its default gateway (Router1), but Router1 cannot forward traffic to the remote subnet.

Answer

PC2 has an incorrect default gateway

Answer

Switch1 is not routing between VLANs

Answer

PC1 has an incorrect subnet mask

Question 12

Answer

1110

Question 15

A company issues smartphones to employees and needs to enforce security policies such as remote wipe and mandatory encryption. Which technology should the IT department implement?

Accepted Answer

MDM. Mobile Device Management (MDM) is the correct technology because it provides centralized policy enforcement for smartphones, including remote wipe, mandatory encryption, passcode requirements, and app management. MDM agents on the device check in with the MDM server (e.g., Intune, Jamf, Workspace ONE) and apply configuration profiles that enforce these controls. This directly matches the stated requirements.
