FC0-U71 Practice Test 38 — 15 Questions

Question 1

A small business office has a network where each device is connected to a central switch. If the switch fails, all devices lose connectivity. Which network topology does this describe?

Accepted Answer

Star topology. In a star topology, every device connects to a central device such as a switch or hub, and all traffic passes through that central point. If the central switch fails, every connected device loses connectivity simultaneously, which matches the scenario described. This single point of failure is the defining characteristic of a star topology.

Answer

Bus topology

Answer

Mesh topology

Answer

Ring topology

Question 2

Which of the following is an example of lossy compression?

Accepted Answer

JPEG. JPEG is a lossy compression format that discards some image data to achieve smaller file sizes, making it the correct example. It uses DCT and quantization to reduce detail, especially in high-frequency areas, which is acceptable for photographs but not for text or line art.

Answer

GIF

Answer

PNG

Answer

ZIP

Question 3

Which of the following is an example of application software?

Accepted Answer

Microsoft Word. Microsoft Word is application software because it is a user-facing program designed to perform a specific productivity task (word processing) on top of the operating system. Application software sits above system software and relies on the OS for hardware access, file management, and process scheduling. Windows 10, BIOS, and the Linux kernel are all system-level components, not end-user applications.

Answer

Windows 10

Answer

BIOS

Answer

Linux kernel

Question 4

A small business wants to replace its on-premises email server with a service where the provider manages the servers, patching, and uptime. Employees will access email through a web browser and mobile apps. Which cloud service model is the business adopting?

Accepted Answer

Software as a Service (SaaS). SaaS is the only model where the provider manages the entire application stack, including servers, patching, and uptime, while users consume the software through a browser or app. IaaS and PaaS leave significant management to the customer, and DaaS delivers desktops rather than a managed email application.

Answer

Platform as a Service (PaaS)

Answer

Desktop as a Service (DaaS)

Answer

Infrastructure as a Service (IaaS)

Question 5

A network administrator is documenting the physical topology of a new office. The design uses a central switch with a dedicated cable to every desk, and the administrator wants to describe the strengths of this layout. Which TWO characteristics accurately describe this topology? (Choose two.)

Accepted Answer

A single cable failure affects only the device connected to that cable. A star topology connects every device to a central switch through its own dedicated cable. This design isolates faults to individual links, so one damaged cable affects only that workstation. The trade-off is that the central switch becomes a single point of failure for the whole network. Shared backbones, cable-path interruptions, and looped traffic describe bus and ring topologies instead.

Answer

Adding a new workstation requires breaking the existing cable path

Answer

All devices share a single common backbone cable

Answer

Data travels in one direction around a closed loop

Question 6

A database has a 'Students' table and an 'Enrollments' table. Which type of relationship exists if a student can enroll in multiple courses and each course can have multiple students?

Accepted Answer

Many-to-many. A many-to-many relationship exists when multiple records in one table are associated with multiple records in another table. Here, a student can enroll in multiple courses, and each course can have multiple students, which is the definition of many-to-many.

Answer

Many-to-one

Answer

One-to-many

Answer

One-to-one

Question 7

A programmer is using a version control system. Which THREE are core Git concepts?

Accepted Answer

Repository. Option B (Repository) is correct because a Git repository is the core storage structure that holds all tracked files, history, and metadata in the .git directory. Option C (Branch) is correct because a branch is a movable pointer to a commit, enabling parallel lines of development in Git. Option D (Commit) is correct because a commit is Git's fundamental snapshot object that records a point-in-time state of the repository along with author, message, and parent references. Option A (Variable) is incorrect because variables are programming-language constructs, not Git concepts. Option E (Compilation) is incorrect because compilation is a build-process step performed by compilers, unrelated to Git's version control model.

Answer

Variable

Answer

Compilation

Question 8

A network technician is troubleshooting a connectivity issue and needs to identify the destination MAC address of a frame. Which TWO of the following are true about MAC addresses? (Select TWO.)

Accepted Answer

They are 48 bits in length. MAC addresses are 48-bit (6 bytes) and commonly represented in hexadecimal. They are assigned by manufacturers and are used at the data link layer.

Answer

They are assigned by the operating system

Answer

They are represented in octal

Answer

They are used at the application layer

Question 9

Which TWO data types are considered unstructured? (Select exactly two.)

Accepted Answer

Email messages. Email messages are considered unstructured data because they contain free-form text, attachments, and metadata that do not conform to a predefined data model or schema. Unlike structured data stored in rows and columns, email content lacks a fixed format, making it difficult to query directly using traditional database tools.

Answer

Spreadsheet cells

Answer

Database records

Answer

Relational data

Question 10

An office has a single shared printer connected via USB to a Windows 10 desktop. Other users in the office need to print to this printer from their own computers, which are connected to the same local network. What is the simplest way to share the printer without additional hardware?

Accepted Answer

Enable printer sharing on the desktop and connect from other computers using the network path. Windows 10 includes built-in printer sharing via the SMB protocol, which allows the printer connected via USB to be shared over the local network without any additional hardware. Enabling printer sharing on the desktop and connecting from other computers using the network path (e.g., \desktop-name\printer-name) is the simplest method that leverages existing network infrastructure.

Answer

Set up a print server using a Raspberry Pi

Answer

Install the printer on each computer by connecting it via USB when needed

Answer

Connect the printer directly to the network switch using an Ethernet cable

Question 11

A user connects to a website using its domain name. Which server translates that domain name into an IP address?

Accepted Answer

DNS server. A DNS (Domain Name System) server translates human-readable domain names like www.example.com into IP addresses that computers use to route traffic. When a user types a domain name, the resolver queries DNS servers to resolve the name to an IP address before the connection can be established.

Answer

Proxy server

Answer

Web server

Answer

DHCP server

Question 12

Which THREE of the following are productivity software suites?

Accepted Answer

Google Workspace. Google Workspace (B) is a cloud-based productivity suite bundling Gmail, Docs, Sheets, Slides, and Drive, so it clearly qualifies. Apache OpenOffice (C) is an open-source office suite containing Writer, Calc, Impress, and Base, making it a classic productivity suite. Microsoft 365 (E) is Microsoft's subscription productivity suite combining Word, Excel, PowerPoint, Outlook, and Teams, so it also qualifies. Slack (A) is a team messaging/collaboration tool rather than a full productivity suite, and Zoom (D) is a video-conferencing service, so neither belongs in this category.

Answer

Slack

Answer

Zoom

Question 13

A user receives an email from their bank asking them to click a link and verify their account information. The email contains spelling errors and the sender's address looks suspicious. Which type of social engineering attack is this?

Accepted Answer

Phishing. This is a phishing attack because it is a broad, untargeted email attempting to trick the recipient into clicking a link and providing account information. The presence of spelling errors and a suspicious sender address are classic indicators of phishing. Phishing typically targets many users indiscriminately, unlike spear phishing which is highly targeted.

Answer

Spear phishing

Answer

Pretexting

Answer

Vishing

Question 14

A user's home wireless network is experiencing interference. Which frequency band is more prone to interference from devices like microwaves and cordless phones?

Accepted Answer

2.4 GHz. The 2.4 GHz frequency band is more prone to interference from common household devices like microwaves, cordless phones, and Bluetooth devices because these devices operate in the same unlicensed ISM band. This band is crowded and only has three non-overlapping channels (1, 6, and 11), making it susceptible to signal degradation. In contrast, 5 GHz and 60 GHz bands are less congested and have more channels, reducing interference.

Answer

60 GHz

Answer

5 GHz

Answer

900 MHz

Question 15

An employee receives an email from 'IT Support' asking for his password due to 'system maintenance'. This is an example of:

Accepted Answer

Phishing. Phishing is a social engineering attack where an attacker masquerades as a trusted entity (here, 'IT Support') to trick the victim into revealing sensitive information, such as a password. The email requesting credentials under the pretext of 'system maintenance' is a classic phishing technique, often executed via email (spear phishing if targeted). This directly matches the definition of phishing as an attempt to acquire sensitive data through deceptive electronic communication.

Answer

Baiting

Answer

Tailgating
