FC0-U71 Practice Test 41 — 15 Questions

Question 1

A technician is troubleshooting a network connectivity issue on a laptop. The laptop connects to the company's wireless network but cannot access the internet. The technician checks the IP configuration and sees an IP address of 169.254.1.5. What is the most likely cause?

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

Accepted Answer

The DHCP server is unreachable.. An IP address in the 169.254.0.0/16 range is an APIPA (Automatic Private IP Addressing) address, which Windows assigns automatically when a DHCP server cannot be reached to obtain a valid lease. Since the laptop has an APIPA address, it can communicate only on the local link and has no default gateway or DNS, so internet access fails. The most likely cause is that the DHCP server is unreachable — either it is down, the DHCP scope is exhausted, or the client cannot reach it due to a network/VLAN issue.

Answer

The DNS server is down.

Answer

The router is misconfigured.

Answer

The network cable is faulty.

Question 2

Which THREE are common steps in troubleshooting software issues?

Accepted Answer

Test the solution. The three correct steps are A, B, and E because they map to the standard troubleshooting methodology: B (Identify the problem) is the essential first phase where you gather information from the user, reproduce the issue, and determine what changed; A (Test the solution) is the verification phase where you confirm the fix actually resolves the issue and check for side effects before closing the ticket; and E (Document findings) is the final phase where you record the problem, cause, and resolution in the knowledge base or ticketing system so future incidents can be resolved faster. C (Reinstall the operating system) is not a routine troubleshooting step — it is a drastic last-resort remediation that destroys data and configuration, not a diagnostic or verification step. D (Replace hardware) is also not a common software-troubleshooting step; it addresses physical faults and would only be considered after diagnostics point to a hardware failure, not as part of the general software troubleshooting process.

Answer

Reinstall the operating system

Answer

Replace hardware

Question 3

Match each operating system to its common environment.

Accepted Answer

Windows: Personal computers and gaming. Common environments: Windows (personal computing/gaming), Linux (servers/development), macOS (creative work). Android is for mobile, Chrome OS for web-based tasks.

Answer

Android: Servers and development

Answer

Chrome OS: Personal computers and gaming

Question 4

Which of the following is a characteristic of open-source software?

Accepted Answer

The source code is available for modification.. Open-source software is defined by its license, which grants users the right to view, modify, and distribute the source code. This characteristic is the core principle of open-source, as codified by the Open Source Initiative (OSI). The ability to modify the source code allows for customization, auditing, and community-driven improvements.

Answer

Users must pay for a license.

Answer

It requires a subscription.

Answer

It can only be used on one device.

Question 5

A company stores customer data in a flat file. Which of the following is a disadvantage of using a flat file compared to a relational database?

Accepted Answer

Flat files do not support concurrent multi-user access. Flat files store data as a single sequential stream of records with no built-in locking, transaction manager, or record-level access control, so two users writing at the same time can overwrite each other's changes or corrupt the file. A relational database management system (RDBMS) provides concurrency control through locking, MVCC, and transactions, allowing many users to read and write safely. This makes concurrent multi-user access the classic disadvantage of flat files.

Answer

Flat files are slower for sequential reads

Answer

Flat files support complex queries

Answer

Flat files enforce referential integrity

Question 6

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

Accepted Answer

Microsoft Teams. Microsoft Teams (C) is a collaboration application because it combines persistent team chat, channels, threaded conversations, file sharing, and integrated voice/video meetings in a single workspace. Slack (E) is likewise a collaboration application, providing channel-based messaging, direct messages, file sharing, and integrations with third-party services for team communication. The remaining options are not collaboration applications: Microsoft Excel (A) is a spreadsheet productivity application, Google Chrome (B) is a web browser, and Adobe Photoshop (D) is an image editing and graphics application.

Answer

Microsoft Excel

Answer

Google Chrome

Answer

Adobe Photoshop

Question 7

Which file extension is typically associated with a compressed archive?

Accepted Answer

.zip. The .zip file extension is the standard for compressed archives, using algorithms like DEFLATE (RFC 1951) to reduce file size and bundle multiple files into a single container. This makes it the correct answer for identifying a compressed archive format.

Answer

.pdf

Answer

.exe

Answer

.docx

Question 8

Question 11

Which SQL statement would you use to retrieve the names of all products with a price greater than $50 from a table named 'Products'?

Accepted Answer

SELECT Name FROM Products WHERE Price > 50. The correct SQL syntax to filter rows is SELECT ... FROM ... WHERE condition. Option A retrieves the Name column from Products where Price exceeds 50, which is exactly the requested query. WHERE is the standard clause for row-level filtering in a SELECT statement, and the comparison operator > correctly expresses 'greater than.'

Answer

SELECT Name FROM Products HAVING Price > 50

Answer

SELECT * FROM Products IF Price > 50

Answer

GET Name FROM Products WHERE Price > 50

Question 12

A security analyst is evaluating risks to the company's network. According to the risk formula (Risk = Likelihood × Impact), which THREE of the following are considered vulnerabilities?

Accepted Answer

Weak encryption used for data in transit. In the risk formula Risk = Likelihood × Impact, vulnerabilities are internal weaknesses or flaws that can be exploited or triggered by a threat. Option A (weak encryption for data in transit) is correct because using outdated or weak ciphers/protocols such as SSLv3, TLS 1.0, or RC4 is a configuration weakness that exposes data to interception. Option D (employees not trained to recognize phishing emails) is correct because lack of security awareness is a human vulnerability that enables social-engineering attacks like credential harvesting. Option E (unpatched software on the company's web server) is correct because missing security patches leave known CVEs exploitable, a classic technical vulnerability. Option B (a hacker attempting to guess passwords) is a threat actor/action, not a vulnerability, and Option C (a fire in the data center) is a physical threat or hazard, not a vulnerability.

Answer

A hacker attempting to guess passwords

Answer

A fire in the data center

Question 13

A user is trying to choose a web browser. Which TWO features are considered advantages of using a browser with built-in developer tools? (Select TWO).

Accepted Answer

Ability to test how a website displays on different screen sizes. Option C is correct because built-in developer tools include responsive design mode (device emulation), which lets you simulate various viewport sizes and device pixel ratios to test how a site renders on different screen sizes. Option E is correct because developer tools provide DOM/CSS inspectors and a JavaScript console that allow you to view, edit, and experiment with a page's HTML, CSS, and scripts in real time. Options A, B, and D are not advantages specific to developer tools: bookmark synchronization is a browser account feature, pop-up and tracker blocking is a privacy feature, and improved page loading speed is a performance characteristic unrelated to the dev tools themselves.

Answer

Automatic synchronization of bookmarks across devices

Answer

Enhanced privacy through blocking of pop-ups and trackers

Answer

Improved page loading speed

Question 14

Which TWO of the following are characteristics of a client-server network? (Choose two.)

Accepted Answer

Clients can be desktop computers, laptops, or smartphones. Client-server networks are designed to support a variety of client devices, including desktop computers, laptops, and smartphones, which all connect to a centralized server to request resources or services. Option B is correct because the defining characteristic of a client-server network is the presence of a centralized server that manages resources, such as file storage, authentication, or database access, and controls access to those resources for all clients.

Answer

All devices are directly connected to each other

Answer

Every device can act as both client and server

Answer

Each device has equal authority and control

Question 15

A user wants to upgrade their desktop computer's RAM for better performance. The motherboard supports dual-channel memory. Which configuration will provide the best performance?

Accepted Answer

Two 8 GB DDR4 modules in paired slots. Dual-channel memory requires matched pairs of identical modules installed in the correct paired slots (often color-coded, e.g., slots 1 and 3 or 2 and 4). Two 8 GB DDR4 modules in paired slots gives 16 GB total with both memory channels active, effectively doubling memory bandwidth compared to single-channel operation. This is the optimal configuration for performance.

Answer

Three 4 GB DDR4 modules

Answer

One 16 GB DDR4 module

Answer

Two 8 GB DDR4 modules in the same channel
