FC0-U71 Practice Test 12 — 15 Questions

Question 1

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 2

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 3

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 4

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 5

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

Answer

MySQL Community Edition

Question 6

Which tool is commonly used for automated testing in software development?

Accepted Answer

Jenkins. Jenkins. Jenkins is a continuous integration tool that automates testing. Docker (D) is for containerization. Git (B) is for version control. Visual Studio (C) is an IDE, but not specifically for automated testing.

Answer

Git

Answer

Visual Studio

Answer

Docker

Question 7

Which TWO of the following are effective measures to protect against ransomware attacks? (Select two.)

Accepted Answer

Installing the latest software updates and patches. Option B is correct because installing the latest software updates and patches closes known vulnerabilities (e.g., SMBv1/EternalBlue, RDP flaws) that ransomware such as WannaCry and NotPetya exploit to gain initial access and propagate laterally. Option D is correct because regularly backing up important files—ideally following the 3-2-1 rule with offline or immutable copies—allows restoration of data without paying a ransom, neutralizing the extortion leverage even if encryption occurs. Option A is wrong because reusing the same password across accounts enables credential-stuffing and lateral movement, dramatically increasing ransomware blast radius rather than protecting against it. Option C is wrong because disabling the firewall removes network traffic filtering and exposes hosts and services to scanning, exploitation, and command-and-control communication. Option E is wrong because opening attachments from unknown senders is a primary ransomware delivery vector via malicious macros, executables, or exploit-laden documents.

Answer

Using the same password for all accounts

Answer

Disabling the firewall

Answer

Opening email attachments from unknown senders

Question 8

A user reports that their laptop's Wi-Fi connection is slow and frequently drops when they are in the living room, but works fine in the office near the router. The router supports both 2.4GHz and 5GHz bands. Which band should the user connect to for better performance in the living room?

Accepted Answer

2.4GHz. The 2.4GHz band has longer wavelength and better wall penetration, so it maintains a usable signal at greater distances and through obstacles like walls between the office and living room. Although 5GHz offers higher throughput at close range, its shorter wavelength causes faster attenuation through walls, explaining the drops in the living room. For range and obstacle penetration, 2.4GHz is the correct choice.

Answer

Cellular

Answer

5GHz

Answer

Bluetooth

Question 9

A company requires employees to use a one-time code from a smartphone app in addition to their password to log into the corporate VPN. This is an example of:

Accepted Answer

Multi-factor authentication. Using a one-time code from a smartphone app in addition to a password combines two different authentication factors: something you know (the password) and something you have (the smartphone app generating the OTP). This satisfies the definition of multi-factor authentication because it uses two distinct factor categories.

Answer

Single factor authentication

Answer

Two-step verification using the same factor

Answer

Biometric authentication

Question 10

A small business owner wants to create a simple website to display business hours and contact information. The owner has no programming experience and needs to quickly update the content without learning code. A family member suggests using a content management system (CMS) like WordPress. Another suggests using a plain HTML file and editing it manually. The owner is concerned about both ease of use and security. Which solution best addresses the owner's needs while minimizing technical complexity?

Accepted Answer

Use a CMS because it provides a graphical interface for content updates.. A CMS like WordPress provides a graphical user interface that allows non-technical users to easily update content such as business hours and contact information without writing code. It also offers security features and plugins to help mitigate risks, addressing the owner's concern about security while minimizing technical complexity. This makes it the best solution for the owner's needs.

Answer

Hire a developer to create a custom application.

Answer

Use a plain HTML file because it does not require a database.

Answer

Use a static site generator but requires command line knowledge.

Question 11

A company wants to ensure that data on lost laptops cannot be accessed. Which technology should be used?

Accepted Answer

Full disk encryption. Full disk encryption (FDE) encrypts the entire storage volume so that if a laptop is lost or stolen, the data is unreadable without the decryption key (typically tied to a TPM or user credential). This directly addresses the requirement that data on lost laptops cannot be accessed, even if the drive is removed and mounted elsewhere.

Answer

VPN

Answer

Firewall

Answer

Antivirus software

Question 12

A user is creating a report that includes several photographs. After saving, the file size is larger than expected. Which data type is primarily responsible?

Accepted Answer

Images. Images, especially high-resolution photographs, contain a large amount of pixel data (e.g., 24-bit color depth per pixel) and are typically stored in uncompressed or losslessly compressed formats like BMP or PNG, resulting in significantly larger file sizes compared to text. The question explicitly mentions 'several photographs,' making images the primary data type responsible for the unexpectedly large file size.

Answer

Audio

Answer

Text

Answer

Video

Question 13

A company's database administrator notices that queries against a large customer table are running slowly. The table has millions of rows and is frequently filtered by the 'last_name' column. Which of the following is the BEST way to improve query performance without changing the application code?

Accepted Answer

Create an index on the 'last_name' column.. Creating an index on the 'last_name' column allows the database to locate rows matching filter conditions without scanning the entire table. This dramatically reduces I/O and CPU overhead for queries that filter by last_name, directly addressing the performance bottleneck without requiring any changes to application code.

Answer

Partition the table by row count.

Answer

Increase the database server's RAM.

Answer

Denormalize the table to reduce joins.

Question 14

An application is displaying an error message: "Cannot write to file. The file may be read-only or in use by another application." Which of the following is the LEAST likely cause?

Accepted Answer

The file has been deleted.. If the file has been deleted, the error message would typically be 'File not found' or 'The system cannot find the file specified,' not a write failure related to read-only status or another application's lock. The error specifically indicates a write conflict or permission issue, not a missing file. Therefore, a deleted file is the least likely cause among the options.

Answer

The file system is full.

Answer

The file is open in another program.

Answer

The user does not have write permissions.

Question 15

A security policy grants the following permissions: Read and List. Based on the policy, what actions are permitted by this policy?

Accepted Answer

Read and List. The policy explicitly grants both the Read and List actions, as is common in many policy configurations. The trap is that candidates may assume Read alone is granted, but List is a separate permission that must be explicitly included.

Answer

Read only

Answer

Read and Delete

Answer

Write and Read
