FC0-U71 Practice Test 5 — 25 Questions

Question 1

A user wants to ensure data is not lost in the event of a drive failure. Which storage configuration provides redundancy?

Accepted Answer

RAID 1. RAID 1 (mirroring) writes identical data to two or more drives simultaneously, so if one drive fails, the data remains accessible from the other drive(s). This provides fault tolerance and ensures no data loss during a single drive failure, meeting the user's requirement for redundancy.

Answer

JBOD

Answer

RAID 0

Answer

Single drive

Question 2

Which of the following best describes the function of a CPU cache?

Accepted Answer

It provides temporary storage for data the CPU needs quickly.. CPU cache is a small, high-speed memory area that stores frequently used data and instructions so the processor can access them faster than fetching from RAM. It sits between the CPU and main memory to reduce latency. This is why cache size and hierarchy significantly affect performance.

Answer

It connects the CPU to the motherboard.

Answer

It stores the operating system permanently.

Answer

It performs arithmetic calculations.

Question 3

A testing team is verifying a new version of an e-commerce website. They run a set of pre-existing test cases to ensure that recent changes have not broken any previously working functionality. What type of testing is this?

Accepted Answer

Regression testing. Regression testing re-runs previously passing test cases after code changes to confirm that new modifications have not broken existing functionality. The scenario describes exactly this: pre-existing test cases are executed to verify that recent changes did not introduce defects in working features. It is a core part of continuous integration pipelines.

Answer

Unit testing

Answer

System testing

Answer

Integration testing

Question 4

A developer needs to track changes to source code over time, collaborate with other developers, and maintain a history of all modifications. Which tool is specifically designed for these tasks?

Accepted Answer

Git. Git is a version control system that tracks changes, enables collaboration, and maintains a history. An IDE is for writing code, a debugger finds errors, and a text editor edits text files but lacks version control features.

Answer

Text editor

Answer

Integrated Development Environment (IDE)

Answer

Debugger

Question 5

A network administrator wants to restrict access to the wireless network to only approved devices. Which security feature should be enabled on the access point?

Accepted Answer

MAC filtering. MAC filtering allows the access point to permit or deny network access based on the device's MAC address, which is a unique hardware identifier. By creating an allowlist of approved MAC addresses, the administrator can restrict the wireless network to only those devices. This directly addresses the requirement to limit access to approved devices.

Answer

Firewall rules

Answer

Disable SSID broadcast

Answer

WPA2 encryption

Question 6

A graphic designer needs to choose a software for vector illustration. Which of the following is best suited?

Accepted Answer

Question 8

Which file system is commonly used on external USB drives for compatibility between Windows and macOS?

Accepted Answer

FAT32. FAT32 is the correct answer because it is natively supported by both Windows and macOS for read and write operations, making it the most compatible file system for external USB drives that need to be used across both platforms. Unlike NTFS (which macOS can only read by default) and APFS (which Windows does not natively support), FAT32 has been a universal standard for cross-platform storage since the 1990s, though it has a 4 GB maximum file size limit.

Answer

APFS

Answer

ext4

Answer

NTFS

Question 9

A user cannot connect to the internet. Which step is most appropriate to start troubleshooting?

Accepted Answer

Check the network cable connection. The most appropriate first step in troubleshooting a network connectivity issue is to check the physical layer (Layer 1 of the OSI model). A loose or unplugged network cable is a common cause of connectivity loss, and verifying the cable connection is quick, non-invasive, and follows the principle of starting with the simplest possible cause before escalating to more complex solutions.

Answer

Update the graphics driver

Answer

Replace the router

Answer

Reinstall the operating system

Question 10

A company needs to store an organizational chart showing reporting relationships. Which database model is most appropriate?

Accepted Answer

Hierarchical. A hierarchical database model is most appropriate for storing an organizational chart because it naturally represents parent-child relationships, such as manager-subordinate reporting lines, in a tree-like structure. This model allows each record to have a single parent and multiple children, directly mirroring the one-to-many relationships in a reporting hierarchy.

Answer

Relational

Answer

Document

Answer

Graph

Question 11

Which cloud service model provides users with access to software applications over the internet without managing the underlying infrastructure?

Accepted Answer

SaaS. SaaS (Software as a Service) delivers fully functional applications over the internet, with the provider managing all underlying infrastructure — servers, storage, networking, and the application itself. The user simply accesses the software via a browser or client, with no responsibility for patching, scaling, or maintaining the platform. Examples include Microsoft 365, Salesforce, and Google Workspace.

Answer

PaaS

Answer

IaaS

Answer

DaaS

Question 12

An attacker gains physical access to a secure area by following an authorized employee through a door that requires a badge. This social engineering technique is known as:

Accepted Answer

Tailgating. Tailgating (or piggybacking) is when an unauthorized person follows an authorized person into a restricted area without proper authentication.

Answer

Pretexting

Answer

Phishing

Answer

Baiting

Question 13

A company needs to connect two separate local area networks (LANs) in different buildings. Which device is required to route traffic between the networks?

Accepted Answer

Router. A router is required to connect two separate LANs because it operates at Layer 3 (Network layer) of the OSI model and uses IP addresses to make forwarding decisions. Unlike switches or bridges, routers can examine the destination IP address, consult a routing table, and forward packets between different subnets or networks, even if they use different data link layer technologies.

Answer

Hub

Answer

Switch

Answer

Bridge

Question 14

A web developer is creating a weather application that retrieves data from a third-party service. The service requires an identifier to track usage and authenticate requests. The developer includes this identifier in the HTTP header of each request. What is this identifier called?

Accepted Answer

API key. An API key is a unique identifier issued by a service provider to authenticate and track a client's usage of its API. It is typically passed in an HTTP header (such as `X-API-Key` or `Authorization`) with each request. This matches the scenario of a weather service requiring an identifier for usage tracking and request authentication.

Answer

JWT

Answer

Session ID

Answer

OAuth token

Question 15

Which of the following is an example of an absolute file path?

Accepted Answer

C:\Users\John\Documents\file.txt. An absolute file path specifies the complete location from the root of the filesystem, leaving no ambiguity about where the file resides. C:\Users\John\Documents\file.txt starts at the drive root (C:\) and walks the full directory tree, so it is absolute on Windows.

Answer

file.txt

Answer

Folder\file.txt

Answer

..\Folder\file.txt

Question 16

A user is selecting a web browser for everyday use. Which of the following is NOT a web browser?

Accepted Answer

Microsoft Teams. Microsoft Teams is a collaboration and unified communications platform, not a web browser. It provides chat, meetings, calling, and file sharing, and although it has a web client, that client runs inside a browser rather than being one. Safari, Firefox, and Chrome are all dedicated web browsers that render HTML, execute JavaScript, and manage HTTP/HTTPS sessions.

Answer

Apple Safari

Answer

Mozilla Firefox

Answer

Google Chrome

Question 17

Which of the following is an example of open-source software license?

Accepted Answer

GPL. The GNU General Public License (GPL) is a widely used free software license that guarantees end users the freedom to run, study, share, and modify the software. It is a classic example of an open-source license because it requires that any modified versions distributed must also be licensed under the GPL, ensuring the software remains open source. Other options like freeware, shareware, and freemium are not open-source licenses; they are distribution models that may not provide source code or the freedom to modify and redistribute.

Answer

Freeware

Answer

Shareware

Answer

Freemium

Question 18

A developer creates a new branch in a version control system to work on a new feature. After completing the feature, the developer wants to combine the changes from the feature branch back into the main branch. What is this process called?

Accepted Answer

Merging. Merging is the process of combining changes from one branch into another — here, taking the completed feature branch and integrating its commits into the main branch. Git performs this via git merge, which either fast-forwards or creates a merge commit.

Answer

Committing

Answer

Forking

Answer

Branching

Question 19

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 20

A database administrator needs to choose a database for an e-commerce application that requires high availability and automatic scaling. Which TWO options are cloud database services?

Accepted Answer

Google Cloud SQL. Google Cloud SQL (B) is a fully managed, cloud-hosted relational database service on Google Cloud Platform that supports MySQL, PostgreSQL, and SQL Server, making it a cloud database service suitable for high availability and scaling needs. Amazon RDS (E) is AWS's managed relational database service that automates provisioning, patching, backups, and Multi-AZ failover, directly matching the e-commerce requirement for high availability and automatic scaling. By contrast, SQLite (A) is an embedded, serverless file-based library, not a cloud service. Microsoft SQL Server Express (C) is a free on-premises edition of SQL Server with size and resource limits, and MySQL Community Edition (D) is a self-managed open-source database typically deployed on your own infrastructure, so neither is a managed cloud database service.

Answer

SQLite

Answer

Microsoft SQL Server Express
