FC0-U71 Practice Test 39 — 15 Questions

Question 1

A software tester writes tests to verify that individual functions in a module return correct results when given specific inputs. These tests are isolated from other parts of the system. Which type of testing is being performed?

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

Accepted Answer

Unit testing. Unit testing is the correct answer because it involves testing individual functions or methods in isolation to verify they return correct outputs for specific inputs. This aligns directly with the scenario where the tester is focusing on single modules without dependencies on other system parts, which is the core definition of unit testing in software development.

Answer

Integration testing

Answer

User acceptance testing

Answer

System testing

Question 2

A program needs to display a message based on a user's age. If age is 18 or over, it displays 'Adult'; otherwise, it displays 'Minor'. Which control structure should be used?

Accepted Answer

If-else statement. The if-else statement is the correct control structure because it evaluates a single condition (age >= 18) and executes one block of code if true ('Adult') and another block if false ('Minor'). This is the standard branching mechanism in most programming languages for binary decisions based on a comparison.

Answer

For loop

Answer

Switch-case statement

Answer

While loop

Question 5

Drag and drop the steps to install a printer on Windows 10 via USB into the correct order.

Accepted Answer

Connect USB cable, turn on printer, wait for automatic driver installation, print test page.. The correct sequence for installing a USB printer on Windows 10 is: connect the USB cable, turn on the printer, let Windows automatically detect and install the driver, and then print a test page to confirm. This order ensures that the printer is recognized by the system before driver installation begins. Option A follows this sequence correctly. Option B is incorrect because the printer must be connected via USB before turning it on for Windows to detect it. Option C is incorrect because turning on the printer after driver installation prevents proper detection. Option D is incorrect because printing a test page before driver installation would fail.

Answer

Turn on printer, connect USB cable, wait for automatic driver installation, print test page.

Answer

Connect USB cable, wait for automatic driver installation, turn on printer, print test page.

Answer

Connect USB cable, turn on printer, print test page, wait for automatic driver installation.

Question 6

A graphic designer is working with a large image file in a proprietary software format. The designer needs to send the image to a client who uses a different operating system and does not have the same software. Which of the following is the BEST method to ensure the client can open the file?

Accepted Answer

Export the file to a commonly used format such as JPEG or PNG.. Exporting the file to a commonly used format like JPEG or PNG ensures cross-platform compatibility without requiring the client to have the proprietary software. JPEG and PNG are standardized, universally supported formats that can be opened by any operating system's default image viewer or basic graphics application, solving the problem of different OS and missing software.

Answer

Compress the file into a ZIP archive before sending.

Answer

Email the client the software license so they can install the same application.

Answer

Change the file extension to .jpg without altering the file contents.

Question 7

An employee receives an email with an attachment that claims to be an invoice. The employee is unsure of the sender. What is the best practice?

Accepted Answer

Delete the email and report it to the IT department.. The safest response to an unsolicited email with an attachment from an unknown sender is to delete it and report it to the IT department. This follows the principle of least privilege and zero-trust security, as opening or interacting with the attachment could trigger a malware payload, such as a macro virus or ransomware, that exploits vulnerabilities in the email client or operating system.

Answer

Forward the email to a personal email for later review.

Answer

Reply to the sender requesting confirmation.

Answer

Open the attachment to verify its contents.

Question 8

Two developers have edited the same file and created different versions. To integrate their changes, which Git operation should they perform?

Accepted Answer

git merge. Git merge. Merging combines changes from different branches into a single branch, integrating the work of both developers. git pull (A) fetches changes from a remote repository and merges them into the current branch, but the question specifically asks for the operation to integrate changes from two different versions (branches) locally, which is merge. git rebase (C) rewrites commit history by reapplying commits on top of another base tip, which is not a direct integration of two versions. git commit (D) saves local changes to the repository but does not integrate changes from another source.

Answer

git pull

Answer

git rebase

Answer

git commit

Question 9

A developer writes code to store a collection of employee names in a structure that allows adding names at the end and removing names from the front, following a first-in-first-out (FIFO) order. Which data structure is the developer implementing?

Accepted Answer

Queue. A queue follows FIFO order: elements are added at the rear and removed from the front.

Answer

Tree

Answer

Array

Answer

Stack

Question 10

A database contains a table 'Orders' with columns OrderID, CustomerID, OrderDate, and TotalAmount. Which THREE SQL statements will correctly insert a new row into the table? (Choose THREE.)

Accepted Answer

INSERT INTO Orders VALUES (1, 101, '2023-01-15', 50.00). The standard SQL INSERT syntax is 'INSERT INTO table_name [(column_list)] VALUES (value_list)'. Option B follows this without a column list, assuming values match table column order. Option E explicitly lists columns, also valid. Option C uses the SET clause, which is an alternative syntax accepted in some database systems like MySQL. While not part of the SQL standard, it is considered correct in contexts that support it. Option A incorrectly places the column list before INTO. Option D omits the required INTO keyword. Therefore, options B, C, and E are correct.

Answer

INSERT (OrderID, CustomerID, OrderDate, TotalAmount) INTO Orders VALUES (1, 101, '2023-01-15', 50.00)

Answer

INSERT Orders VALUES (1, 101, '2023-01-15', 50.00)

Question 11

A user is trying to install a new printer driver on a Windows 10 workstation but receives an error stating the driver is not signed. Which security concept is most directly involved?

Accepted Answer

Authentication. Driver signing involves digital signatures that verify the publisher's identity, which is a form of authentication. The error indicates the driver is not signed, meaning the publisher cannot be authenticated. Therefore, authentication is the security concept most directly involved.

Answer

Availability

Answer

Integrity

Answer

Confidentiality

Question 12

A REST API is used by a mobile app to retrieve data. The API returns responses in a specific format. Which THREE of the following are typical characteristics of a REST API?

Accepted Answer

Is stateless between requests. REST APIs are stateless by design, meaning each request from a client to the server must contain all the information needed to understand and process the request. The server does not store any client context between requests, which improves scalability and reliability. This statelessness is a core constraint of the REST architectural style, as defined by Roy Fielding in his doctoral dissertation.

Answer

Uses SOAP for message exchange

Answer

Maintains server-side session state

Question 13

A network technician is configuring a device and needs to enter a MAC address. Which of the following is a valid MAC address in hexadecimal notation?

Accepted Answer

3A:4B:5C:6D:7E:8F. MAC addresses are 12 hexadecimal digits (0-9, A-F), typically displayed in pairs separated by colons, e.g., 3A:4B:5C:6D:7E:8F. Option A uses letters beyond F (G, H, I, J, K, L) which are not hex digits. Option B has only 6 digits (AB:CD:EF), which is too few. Option D uses Z, Y, W which are not valid hex digits. Only option C meets the requirements: 12 hex digits using only 0-9 and A-F.

Answer

1G:2H:3I:4J:5K:6L

Answer

AB:CD:EF

Answer

0X:1Z:2Y:3X:4W:5V

Question 14

A user is working on a presentation for a client meeting. The user has been using Microsoft PowerPoint and has completed the slides. The user now needs to create handouts for the audience so they can follow along. The handouts should show the slides with space for notes. Which of the following is the BEST way to create these handouts?

Accepted Answer

Use PowerPoint's handout feature to print slides with note lines.. PowerPoint's handout feature is specifically designed to create printed handouts that include slide thumbnails and adjacent note lines for audience notes. This built-in functionality (File > Print > Handouts) allows you to select the number of slides per page and automatically adds ruled lines for note-taking, making it the most efficient and correct method for this task.

Answer

Print the presentation with full-page slides.

Answer

Manually copy each slide into a word processing document.

Answer

Take screenshots of each slide and arrange them in a document.

Question 15

A software development team follows a methodology where work is divided into fixed sequential phases: requirements, design, implementation, testing, deployment, and maintenance. Changes to requirements are difficult once a phase is completed. Which development methodology is being used?

Accepted Answer

Waterfall. The Waterfall model is a linear sequential software development methodology where each phase (requirements, design, implementation, testing, deployment, maintenance) must be completed before the next begins. This rigidity makes it difficult to accommodate changes to requirements once a phase is finished, exactly as described in the question.
