FC0-U71 Practice Exam 64 — 20 Questions

Question 1

A technician needs to connect a new desktop computer to a wired network in an office where the wall jack is active and the network uses DHCP. The computer has an integrated RJ45 port. Which of the following should the technician do to enable network connectivity?

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

Accepted Answer

Connect an Ethernet cable from the wall jack to the computer's RJ45 port. With an active wall jack, an integrated RJ45 port, and DHCP in place, the only required action is to connect a standard Ethernet cable between the jack and the computer. DHCP will handle IP configuration automatically. Wireless, static addressing, and Internet Connection Sharing are either unnecessary or incorrect for this wired scenario.

Answer

Assign a static IP address in the same subnet as the gateway

Answer

Install a wireless network adapter and configure the SSID

Answer

Enable Internet Connection Sharing on the computer

Question 2

A technician is connecting a desktop PC directly to a cable modem to provide internet access. The PC needs to receive a public IP address automatically from the ISP. Which protocol should the technician ensure is enabled on the PC's network adapter?

Accepted Answer

DHCP. The PC must obtain a public address from the ISP without manual entry, which is the role of DHCP. The ISP's DHCP server leases the address along with gateway and DNS details. DNS, SMTP, and SNMP serve naming, email, and management functions respectively and cannot assign an address to the adapter.

Answer

DNS

Answer

SNMP

Answer

SMTP

Question 3

A technician is configuring a laptop for a user who frequently travels and needs to connect to both wired and wireless networks. The laptop has an RJ45 port and supports Wi-Fi 6. Which statement accurately describes the role of the network interface card (NIC) in this scenario?

Accepted Answer

The NIC provides the physical and data link layer connection for both wired and wireless communication.. The NIC is responsible for the physical and data link layer functions, enabling the laptop to communicate over Ethernet and Wi-Fi. Modems convert digital to analog, DHCP servers assign IP addresses, and routers route packets between networks, so those roles belong to other devices.

Answer

The NIC assigns IP addresses to other devices on the network.

Answer

The NIC converts digital signals to analog for transmission over the internet.

Answer

The NIC routes packets between different networks.

Question 4

A developer is writing a program that must handle multiple tasks simultaneously, such as downloading files while updating a user interface. Which programming concept allows the program to execute multiple sequences of instructions concurrently?

Accepted Answer

Multithreading. Multithreading allows a single program to execute multiple threads simultaneously, each performing a different task. This is ideal for scenarios like downloading files in the background while keeping the user interface responsive. Other concepts like recursion, OOP, or event-driven programming do not inherently provide concurrent execution of multiple instruction sequences.

Answer

Recursion

Answer

Event-driven programming

Answer

Object-oriented programming

Question 5

A technician is troubleshooting a computer that randomly reboots during use. The technician suspects a hardware issue. Which of the following tools would be MOST appropriate to monitor the system's temperature and voltage readings in real time?

Accepted Answer

Hardware monitoring software. Hardware monitoring software is designed to track system temperatures and voltages in real time, making it ideal for diagnosing random reboots potentially caused by overheating or power issues. A multimeter, loopback plug, and POST card serve different purposes and cannot provide continuous monitoring of these parameters.

Answer

Loopback plug

Answer

POST card

Answer

Multimeter

Question 6

A technician is preparing a desktop workstation for a user who needs to run several virtual machines locally for software testing. The host must have enough resources to keep the virtual machines responsive while the desktop remains usable. Which TWO hardware upgrades would most directly support this workload? (Choose two.)

Accepted Answer

A CPU with more cores. Running multiple virtual machines locally consumes processor cores and memory above what the host operating system needs. More cores let guests execute in parallel, and additional RAM prevents the host from paging virtual machine memory to disk. Graphics, power, and optical drive upgrades do not address the core resource demands of this workload.

Answer

A discrete graphics card

Answer

A larger power supply

Answer

A faster optical drive

Question 7

A help desk technician receives a call from someone claiming to be a company vice president who is traveling and urgently needs their password reset over the phone. The caller's number matches an internal extension. Which action should the technician take FIRST?

Accepted Answer

Verify the caller's identity using the organization's established out-of-band procedure.. Urgency and a spoofable phone number are classic pretexting indicators. The technician should first confirm the caller's identity through the organization's out-of-band verification procedure, such as calling back a number from the directory or using a shared challenge. Only after verification should any password reset occur, which protects high-value accounts while still serving legitimate users.

Answer

Provide a temporary password that expires in one hour and end the call.

Answer

Reset the password immediately to avoid delaying the executive.

Answer

Ask the caller to email the request from their company address instead.

Question 8

A technician is assembling a desktop PC for a video editor. The editor frequently transfers large project files to and from external drives and wants the fastest currently available consumer interface. Which interface should the technician prioritize on the motherboard?

Accepted Answer

Thunderbolt 4. The editor needs the fastest consumer external interface for large project files, and Thunderbolt 4 delivers up to 40 Gbps over USB-C. USB 2.0, eSATA, and FireWire 800 are all far slower and largely legacy, so they cannot meet the performance requirement. Thunderbolt 4 is the only listed option that provides current top-tier throughput.

Answer

FireWire 800

Answer

eSATA

Answer

USB 2.0

Question 9

A small business wants to set up a network where employees can share files and a printer without a dedicated server. The budget is limited, and the network should be easy to set up. Which type of network model is most appropriate?

Accepted Answer

Peer-to-peer. A peer-to-peer network lets computers share files and printers directly without a dedicated server, matching the small business's budget and simplicity requirements. Client-server needs a server, a VPN is for secure remote access, and a SAN is enterprise storage infrastructure.

Answer

Client-server

Answer

Storage area network

Answer

Virtual private network

Question 10

A technician is preparing a workstation for a user who needs to work with several document types. The technician wants to confirm which file extensions are commonly associated with word-processing documents and which are commonly associated with spreadsheets. Which TWO file extensions are typically used for spreadsheet files? (Choose two.)

Accepted Answer

.csv. Spreadsheet applications work with row-and-column data, and the extensions most closely tied to that model are .xlsx for native workbooks and .csv for plain-text tabular data. Word-processing, presentation, and portable document formats serve different content types and open in different applications, so they are not spreadsheet extensions. Recognizing these associations helps a technician map file types to the right software.

Answer

.pdf

Answer

.pptx

Answer

.docx

Question 11

A user needs to create a document that includes complex mathematical equations, automatic table of contents, and collaborative editing with change tracking. Which type of application is most appropriate?

Accepted Answer

Word processor. A word processor is specifically built for creating documents that require advanced formatting, such as mathematical equations, automatic table of contents, and collaborative editing with change tracking. These features are standard in applications like Microsoft Word and Google Docs, which are designed for text-centric tasks. The other application types focus on different data types and lack these capabilities.

Answer

Database management system

Answer

Presentation software

Answer

Spreadsheet

Question 12

A small business wants to deploy a new customer relationship management (CRM) application. The company has no in-house IT staff and wants to minimize upfront infrastructure costs. They also need to access the CRM from any device with a browser. Which of the following deployment models best fits these requirements?

Accepted Answer

Software as a Service (SaaS). SaaS is the correct choice because it provides a fully managed application accessible via a web browser, with no need for local infrastructure or IT staff. The subscription model aligns with minimizing upfront costs. PaaS and IaaS require more technical management, and on-premises demands significant capital and maintenance, making them unsuitable for this scenario.

Answer

Infrastructure as a Service (IaaS)

Answer

On-premises

Answer

Platform as a Service (PaaS)

Question 13

A user reports that their laptop display looks extremely dim even though the image is visible and the operating system is running normally. The screen becomes readable when a flashlight is aimed at it. Which component has most likely failed?

Accepted Answer

The inverter or backlight. The telltale sign of a failed backlight or inverter is an image that is present but nearly invisible until external light strikes the screen. The panel and signal path still function, so the fault lies with the illumination subsystem rather than the GPU, cable, or digitizer.

Answer

The digitizer

Answer

The graphics processing unit

Answer

The display cable

Question 14

A user is configuring backup software on a workstation. The user wants the backup job to run automatically every night, capture only files that changed since the last run, and avoid re-copying files that have not been modified. The backup destination is a local external drive. Which backup type should the user select?

Accepted Answer

Incremental backup. The requirement is to capture only data that changed since the previous backup while skipping untouched files. Incremental backups track the last backup of any kind and copy only newly modified files, keeping each nightly run minimal. Full backups duplicate everything, differential backups re-copy all changes since the last full backup, and mirror backups replicate the current state without version history, so none of those match the stated goals.

Answer

Mirror backup

Answer

Differential backup

Answer

Full backup

Question 15

A small business owner wants to secure the wireless network at a retail store. The owner wants customers to have internet access without needing a password, but also wants to keep the internal point-of-sale (POS) network separate and protected. Which of the following should the owner configure?

Accepted Answer

Set up a guest network with SSID isolation and client isolation enabled.. The requirement is to give customers open internet access while keeping the POS network protected. A separate guest network with client isolation achieves this by segmenting traffic and preventing guests from reaching internal devices. Other options either require credentials, do not segment traffic, or rely on easily bypassed controls.

Answer

Enable WPA3-Personal on the main network and share the passphrase only with employees.

Answer

Configure MAC address filtering to allow only known customer devices on the wireless network.

Answer

Disable SSID broadcasting on the wireless access point.

Question 16

A help desk technician is comparing storage capacity specifications for two laptops. One specification lists the SSD as 512 GB and the other lists it as 512 GiB. The technician needs to explain to a customer why the operating system reports a lower usable capacity than the advertised number. Which of the following best explains this difference?

Accepted Answer

GB uses powers of 1000 while GiB uses powers of 1024, so the same physical capacity is reported as a smaller number when measured in GiB. The apparent capacity loss occurs because manufacturers advertise decimal gigabytes based on powers of 1000, while many operating systems report binary gibibytes based on powers of 1024. Since a gibibyte is about 7.4 percent larger than a gigabyte, the same physical drive shows a smaller number in GiB. Recognizing this unit distinction lets the technician explain the discrepancy accurately.

Answer

The operating system reserves part of the drive for the file system, so the missing capacity is always exactly the formatting overhead

Answer

GiB measures only the cache portion of the drive while GB measures the full platter area available to the user

Answer

GB is used for solid-state drives and GiB is used for magnetic hard drives, so the two laptops are using different storage technologies

Question 17

A developer is writing the first version of a program that calculates an employee's weekly pay. Before writing any code, the developer writes a numbered list of steps in plain English: get hours worked, get hourly rate, multiply hours by rate, display the result. Which software development concept does this numbered list represent?

Accepted Answer

An algorithm. The plain-English, ordered steps that describe how to compute weekly pay constitute an algorithm, which is a finite sequence of instructions that transforms input into output. Writing the algorithm before coding helps the developer verify the logic and translate it into a programming language later. Compilers translate code, variables store values, and databases store data, so none of those describe the full procedure.

Answer

A variable

Answer

A database

Answer

A compiler

Question 18

A technician is explaining the concept of cloud computing to a new employee. Which TWO of the following are characteristics of cloud computing as defined by NIST? (Choose two.)

Accepted Answer

On-demand self-service. The NIST definition of cloud computing includes five essential characteristics: on-demand self-service, broad network access, resource pooling, rapid elasticity, and measured service. On-demand self-service and broad network access are two of these. Dedicated hardware, manual provisioning, and limited scalability are not characteristics of cloud computing.

Answer

Manual provisioning of resources

Answer

Limited scalability

Answer

Dedicated physical hardware for each customer

Question 19

A technician is explaining data representation to a trainee. The trainee asks which of the following statements correctly describe how bits and bytes are used in computing. (Choose two.)

Accepted Answer

A bit is the smallest unit of data and can have a value of 0 or 1.. A bit is the smallest unit of data, holding a 0 or 1, and a byte is 8 bits, capable of representing 256 values. These two statements accurately describe fundamental data representation. The other options incorrectly describe bit capacity, byte size, or binary-to-decimal mapping, so they are not correct.

Answer

A bit can represent decimal numbers directly without conversion.

Answer

A byte is always equal to 10 bits in modern computing systems.

Answer

A bit can store multiple characters, while a byte stores only one.

Question 20

A small business stores customer orders in a relational database. The Orders table has a foreign key column named CustomerID that references the Customers table. A developer needs to prevent any order from being inserted if the CustomerID does not already exist in the Customers table. Which database feature should be used?

Accepted Answer

A referential integrity constraint. Referential integrity is the relational database rule that a foreign key must reference an existing primary key. It blocks inserts or updates that would create an order with a nonexistent CustomerID. Unique constraints, default values, and indexes serve different purposes and do not validate the relationship between the Orders and Customers tables.

Answer

A unique constraint on the CustomerID column in the Orders table

Answer

A default value of 0 for the CustomerID column

Answer

An index on the CustomerID column in the Orders table
