FC0-U71 Practice Exam 57 — 20 Questions

Question 1

A technician is building a virtualization host that will run multiple virtual machines simultaneously. The host needs to support hardware-assisted virtualization and provide the best performance for VMs that require direct access to peripheral devices. Which of the following CPU features should the technician verify is enabled in the BIOS/UEFI?

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

Accepted Answer

Intel VT-x or AMD-V. Hardware-assisted virtualization extensions, such as Intel VT-x and AMD-V, are fundamental for running virtual machines efficiently. They enable the hypervisor to execute privileged instructions directly on the CPU and are a prerequisite for advanced features like PCI passthrough, which grants VMs direct access to peripherals. Verifying that these are enabled in BIOS/UEFI ensures optimal VM performance and functionality.

Answer

Execute Disable Bit (XD) or No-eXecute (NX)

Answer

Intel Turbo Boost or AMD Precision Boost

Answer

Simultaneous Multithreading (SMT) or Hyper-Threading

Question 2

A help desk technician is setting up a new laptop for a remote employee. The employee needs to copy a 6 GB video file onto the laptop, which has a 256 GB solid-state drive. Which of the following storage interfaces would provide the fastest transfer speed for an external drive connected to this laptop?

Accepted Answer

USB 3.2 Gen 2. USB 3.2 Gen 2 delivers up to 10 Gbps, making it the fastest among the listed interfaces. For transferring a large 6 GB video file, speed is critical. USB 2.0, eSATA, and FireWire 800 are all slower and less practical for modern laptops. Therefore, USB 3.2 Gen 2 is the best choice.

Answer

FireWire 800

Answer

USB 2.0

Answer

eSATA

Question 3

A small business owner needs to connect three desktop computers, a network laser printer, and a broadband router in a single office. The budget is tight, and the owner wants the simplest possible wired setup that allows all devices to communicate on the same local network. Which of the following should the owner install?

Accepted Answer

An unmanaged Ethernet switch. The office needs a central device to interconnect wired computers, a printer, and a router. An unmanaged Ethernet switch fulfills this by offering multiple ports and automatic operation with no configuration. It is cost-effective and simple, matching the owner's budget and ease-of-use requirements. Other options either provide security, wireless access, or cable management but not the essential wired connectivity.

Answer

A wireless access point

Answer

A hardware firewall appliance

Answer

A patch panel

Question 4

A small office wants wireless devices to connect to the corporate network without running cables to each desk. The administrator must choose a technology that provides wireless local area network connectivity using radio frequencies. Which technology should be selected?

Accepted Answer

Wi-Fi. Wi-Fi, standardized under IEEE 802.11, is the technology built specifically for wireless local area networking over radio frequencies. It provides the range, client density, and throughput that an office needs, unlike Bluetooth and NFC, which serve short-range personal connections, or infrared, which requires direct line of sight and offers limited bandwidth.

Answer

NFC

Answer

Bluetooth

Answer

Infrared

Question 5

A small business wants to centralize data storage so that employees on both Windows and macOS systems can access shared files with permissions. The company has a limited budget and wants to avoid recurring cloud subscription fees. Which of the following should the technician implement?

Accepted Answer

A network-attached storage (NAS) device. A NAS device is designed for centralized file sharing on a local network, supports permissions, and works with both Windows and macOS clients. It avoids recurring cloud fees and is more affordable and manageable than a SAN. The other options either do not provide network-wide shared access, are too complex, or violate the no-subscription requirement.

Answer

A direct-attached storage (DAS) enclosure

Answer

A storage area network (SAN)

Answer

A cloud storage subscription

Question 6

A technician is documenting the physical networking hardware in a small office wiring closet and needs to distinguish devices that forward data between network segments from devices that only regenerate signals. Which TWO of the following devices actively forward frames or packets between network segments? (Choose two.)

Accepted Answer

Switch. Switches and routers both inspect addressing information and make forwarding decisions, with switches operating on MAC addresses within a local network and routers operating on IP addresses between networks. Hubs, media converters, and patch panels lack that decision-making logic, either repeating signals, translating media, or simply organizing cabling.

Answer

Media converter

Answer

Hub

Answer

Patch panel

Question 7

A small business wants its staff to create documents, spreadsheets, and presentations without installing any software on their laptops. Staff must be able to open the files from any company device and see edits made by coworkers within seconds. Which software delivery model best meets this requirement?

Accepted Answer

Cloud-based productivity suite accessed through a web browser. The requirement combines zero local installation with near-real-time multi-user editing across devices. Only a browser-accessed cloud productivity suite delivers both natively, because the application and the documents live in the provider's environment and synchronization is handled by the service. Locally installed, portable, and virtualized desktop options all keep execution on or near the endpoint and lack native simultaneous co-editing.

Answer

Virtual desktop infrastructure hosting a published desktop with office applications

Answer

Open-source office suite installed from a portable USB drive

Answer

Locally installed proprietary productivity suite licensed per seat

Question 8

A user is compiling a report and needs to combine text, a chart, and a table from three separate files into one document while preserving the original formatting of each element. Which productivity application feature is designed for this task?

Accepted Answer

Object linking and embedding (OLE). Object linking and embedding lets a document host content created in other applications while preserving that content's original formatting, which is exactly what combining a chart and a table from separate files requires. Mail merge, Track Changes, and macros serve different purposes and do not provide embedded, format-preserving objects.

Answer

Macros

Answer

Mail merge

Answer

Track Changes

Question 9

A technician must install a critical security update on 150 Windows 11 computers overnight without visiting each desk. The update is distributed as an .msi package, and the organization already uses Active Directory Domain Services. Which method should the technician use?

Accepted Answer

Group Policy software installation. Group Policy software installation is the built-in Active Directory mechanism for silently deploying .msi packages to many domain-joined computers at once. Manual USB installation requires physical access, the Microsoft Store only handles Store apps, and Windows Update for Business only manages Microsoft updates, so Group Policy is the only method that meets all constraints.

Answer

Windows Update for Business

Answer

Microsoft Store automatic updates

Answer

Manual installation from a USB drive

Question 10

A small business wants to connect its office to a fiber internet service. The ISP provides an optical network terminal (ONT) that converts the fiber signal to Ethernet. The business needs a device that will route traffic between the internal LAN and the ISP, perform NAT, and provide DHCP to internal clients. Which device should the technician install between the ONT and the LAN switch?

Accepted Answer

A router. The device between an ONT and an internal switch must route packets, translate private addresses to the public address, and assign IP configuration to clients. A router provides all three functions at Layer 3. Switches, access points, and media converters operate at lower layers or serve different purposes and cannot fulfill the routing and NAT requirements of this scenario.

Answer

A media converter

Answer

A Layer 2 switch

Answer

A wireless access point

Question 11

A small retail company stores customer orders in a relational database. The IT administrator wants each order record to automatically receive a unique number without manual entry when a new order is inserted. Which database feature should be configured to meet this requirement?

Accepted Answer

Set the OrderID column as an AUTO_INCREMENT (or IDENTITY) column.. The requirement is automatic generation of a unique number for each new order. An AUTO_INCREMENT or IDENTITY column is the standard relational database feature that produces a sequential unique value on insert, removing manual entry and preventing duplicates. Other options either require manual input, only validate data, or enforce referential integrity without generating values.

Answer

Add a CHECK constraint that verifies the OrderID is numeric.

Answer

Define a foreign key on the OrderID column referencing the CustomerID column.

Answer

Create a stored procedure that prompts the user to enter the next order number.

Question 12

A junior developer is writing a program that must repeatedly ask the user for a password until the correct password is entered. The developer needs a programming construct that will keep running the same block of code while a condition remains true. Which programming concept should the developer use?

Accepted Answer

A loop. The requirement is repetition based on a condition, which is the definition of a loop. A loop checks its condition and repeats the enclosed statements until the condition becomes false, so placing the password prompt inside a loop that continues while the password is incorrect achieves the desired behavior. Other constructs such as functions, variables, and conditional statements control structure or storage but do not inherently repeat code.

Answer

A conditional statement

Answer

A function

Answer

A variable

Question 13

A junior developer is asked to write a program that reads a user's age and determines whether the user is eligible to vote. The program must compare the age to 18 and display one of two messages. Which programming construct is the most appropriate to use for this decision-making step?

Accepted Answer

An if-else statement. The task requires selecting one of two outcomes based on whether the age meets a threshold, which is exactly what conditional branching provides. An if-else statement evaluates a Boolean expression and routes execution to the appropriate block. Loops, variable declarations, and function definitions support other concerns such as repetition, storage, and reuse, but none of them performs the required true-or-false decision.

Answer

A for loop

Answer

A function definition

Answer

A variable declaration

Question 14

A development team is choosing a version control workflow for a project with multiple contributors. They want to keep the main branch stable and allow each developer to work independently before changes are reviewed and integrated. Which THREE of the following are characteristics of a typical branch-based version control workflow? (Choose three.)

Accepted Answer

Developers create separate branches to isolate work on features or fixes.. A branch-based workflow isolates work by letting developers create branches for features or fixes, supports parallel development without disturbing others, and integrates changes into main only after review. Direct commits to main and permanently unsynchronized repository copies do not fit this model because they either bypass review or prevent effective integration and collaboration.

Answer

Each developer maintains a completely separate copy of the repository that never syncs.

Answer

All developers commit directly to the main branch without review.

Question 15

A programmer is writing a function that must decide whether a customer qualifies for a discount. The function checks if the customer's total purchases are greater than 500. If true, it returns a discount rate; otherwise, it returns zero. Which programming construct is most appropriate for making this decision?

Accepted Answer

A conditional statement such as if-else.. The requirement is a single decision with two possible outcomes based on whether total purchases exceed 500. A conditional statement such as if-else evaluates the condition and selects the appropriate result. Loops repeat actions, variable declarations store data, and function calls retrieve values, but none of those directly perform the branching decision needed here.

Answer

A function call that returns the customer's total purchases.

Answer

A variable declaration that stores the discount rate.

Answer

A loop that repeats the check until the value changes.

Question 16

A junior database administrator is reviewing the structure of a relational database used by a library. The database contains a Books table, a Members table, and a Loans table that records which member borrowed which book and the loan date. Which TWO of the following statements accurately describe the role of the Loans table in this database? (Choose two.)

Accepted Answer

It contains foreign keys that reference the primary keys of both the Books and Members tables.. The Loans table is a junction table that resolves the many-to-many relationship between Books and Members by containing foreign keys to both. It does not duplicate book details, does not remove the need for primary keys, and is not a NoSQL document store. These characteristics are fundamental to relational database design and normalization.

Answer

It is an example of a NoSQL document store.

Answer

It stores the complete details of each book, including title, author, and ISBN.

Answer

It eliminates the need for a primary key in the Books table.

Question 17

A user is choosing a backup strategy for a laptop that contains important documents. The user wants copies of files stored in a second location and wants to be able to restore an earlier version of a file that was accidentally modified. Which TWO actions should the user perform? (Choose two.)

Accepted Answer

Copy important files to an external USB drive regularly.. A sound backup strategy needs both a second copy in a different location and the ability to recover earlier file versions. Copying to an external USB drive provides redundancy, while File History automatically maintains versioned backups on a separate drive. Maintenance tasks such as Disk Cleanup and defragmentation do not create backups, and a ZIP archive on the same drive offers neither off-device protection nor version history.

Answer

Run Disk Cleanup to remove temporary files from the system drive.

Answer

Defragment the hard drive to improve file access speed.

Answer

Create a compressed ZIP archive of the files on the same drive.

Question 18

A user needs to retrieve only the 'ProductName' and 'Price' columns from a table named 'Products' where the 'Category' is 'Electronics'. Which SQL statement should the user execute?

Accepted Answer

SELECT ProductName, Price FROM Products WHERE Category = 'Electronics';. The SQL SELECT statement retrieves data from a table. To get specific columns, you list them after SELECT. To filter rows, you use the WHERE clause. The correct statement selects ProductName and Price from Products and filters where Category equals 'Electronics'. This precisely meets the user's need to view only electronics products with their names and prices.

Answer

SELECT ProductName, Price FROM Products HAVING Category = 'Electronics';

Answer

SELECT * FROM Products WHERE Category = 'Electronics';

Answer

SELECT ProductName, Price FROM Products ORDER BY Category = 'Electronics';

Question 19

A user receives a document created in a word processor that the user does not own. The sender wants the user to be able to read the text and view the layout, but the user does not need to edit or save changes. Which action allows the user to view the document content most reliably?

Accepted Answer

Open the file in a free viewer or reader application that supports the format. To view a document reliably without owning the authoring application, the user needs software that understands the file format and can render it faithfully. A viewer or reader application is designed for exactly this purpose, displaying text, images, and layout while typically restricting editing. Text editors strip formatting, renaming extensions does not convert content, and printing sacrifices the digital advantages of the file.

Answer

Change the file extension to match a format the user's software supports

Answer

Request that the sender print the document and mail a physical copy

Answer

Open the file in a plain text editor

Question 20

A team is preparing to release a software product and wants to automate checks that run whenever code is committed. They are selecting practices that belong to continuous integration. Which two of the following are core continuous integration practices? (Choose two.)

Accepted Answer

Automatically building the application after each commit to detect integration errors early. Continuous integration means developers integrate work into a shared mainline frequently and verify each integration automatically. Automated builds catch compile and integration errors immediately, and automated tests confirm that existing behavior still works. Together these practices provide fast feedback. Long-lived branches, manual quarterly releases, and disabled tests all work against that goal by delaying or removing the checks that make frequent integration safe.

Answer

Requiring developers to keep feature branches open for months before merging

Answer

Manually deploying the application to production once per quarter

Answer

Disabling automated tests on the main branch to speed up builds
