FC0-U71 Practice Questions

Question 1

Which of the following is an example of a PAN (Personal Area Network) technology?

Accepted Answer

Bluetooth. Bluetooth is a short-range wireless technology designed to connect devices within a person's immediate vicinity (typically 10 meters or less), which is the defining characteristic of a Personal Area Network (PAN). It operates in the 2.4 GHz ISM band using frequency-hopping spread spectrum and is used for peripherals like headsets, keyboards, and smartphones. This makes it the textbook example of PAN technology.

Answer

Cellular

Answer

Wi-Fi

Answer

Ethernet

Question 2

A home user wants to connect a desktop computer to the internet using a wireless connection. The computer does not have built-in Wi-Fi. What is the simplest and most cost-effective solution? The user has a wireless router already installed and working.

Accepted Answer

Install a wireless network adapter (USB or PCIe). A wireless network adapter (USB or PCIe) adds Wi-Fi capability to a desktop that lacks it, directly connecting to the existing wireless router. This is the simplest and most cost-effective solution because it requires no new infrastructure or cabling, and USB adapters are plug-and-play with minimal setup.

Answer

Use a powerline adapter to extend the network

Answer

Replace the computer with a laptop that has Wi-Fi

Answer

Run an Ethernet cable from the router to the computer

Question 3

A network administrator wants to automatically assign IP addresses to all devices on the network. Which service should be configured on the server?

Accepted Answer

DHCP. Dynamic Host Configuration Protocol (DHCP) is the correct service because it automatically assigns IP addresses, subnet masks, default gateways, and other network configuration parameters to devices on a network. This eliminates the need for manual static IP configuration and ensures each device receives a unique IP address from a defined pool, preventing address conflicts.

Answer

DNS

Answer

HTTP

Answer

NAT

Question 4

A small accounting firm's wireless network currently uses WPA2-Personal with a shared passphrase that all 20 employees know. The office manager reports that a former contractor who was given the passphrase can still connect to the Wi-Fi from the parking lot. The firm wants each user to authenticate with their own unique credentials and wants to be able to revoke access for one person without disrupting everyone else. Which wireless security method should the firm implement?

Accepted Answer

WPA2-Enterprise with 802.1X authentication against a RADIUS server. The firm needs two things a shared passphrase cannot provide: distinct credentials per person and the ability to cut off one account without rekeying the whole office. WPA2-Enterprise pairs 802.1X with a RADIUS server so each login is validated individually against a directory, and disabling the contractor's account instantly blocks that person. Personal modes, MAC filtering, and WPS all rely on a network-wide secret or device identifiers rather than user identity.

Answer

MAC address filtering on the wireless access point

Answer

Wi-Fi Protected Setup (WPS) with push-button configuration for each employee

Answer

WPA3-Personal with Simultaneous Authentication of Equals (SAE)

Question 5

A developer is writing pseudocode for a program that calculates the average of a list of numbers. Which THREE of the following are valid components that would likely appear in the pseudocode? (Select THREE.)

Accepted Answer

Initialize sum to 0. Initializing a variable (like sum) to a starting value (0) is a fundamental step in accumulation algorithms. Without this initialization, the sum would contain an undefined or garbage value, leading to incorrect results. This is a standard practice in pseudocode and real programming languages alike.

Answer

Define a class named Calculator

Answer

Execute SQL query to retrieve numbers from database

Question 6

Question 7

Refer to the exhibit. A developer wrote this BASIC program. What will happen if the user presses Enter without typing a name?

Accepted Answer

The program will print "Hello, " with no name.. The program shown in the exhibit likely uses a simple INPUT statement to read a name, followed by a PRINT statement that outputs 'Hello, ' and the entered value. If the user presses Enter without typing anything, the INPUT statement reads an empty string into the name variable. Consequently, the program prints 'Hello, ' with nothing after it. There is no validation to re‑prompt or check for an empty input, so no error occurs and the program does not loop.

Answer

The program will display an error message.

Answer

The program will prompt for input again.

Answer

The program will end with no output.

Question 8

A user runs a query on a database table and notices that the results contain duplicate rows. Which SQL keyword would eliminate these duplicates?

Accepted Answer

DISTINCT. The DISTINCT keyword in SQL is used within a SELECT statement to remove duplicate rows from the result set. When a query returns multiple identical rows, DISTINCT filters them out so that only unique combinations of column values are displayed. This directly addresses the user's requirement to eliminate duplicate rows.

Answer

GROUP BY

Answer

WHERE

Answer

ORDER BY

Question 9

Which of the following are advantages of using a cloud database service (DBaaS) compared to an on-premises database? (Select TWO.)

Accepted Answer

Managed maintenance and updates. DBaaS provides managed maintenance and automatic scalability without hardware management. High availability is inherent, and initial cost is lower (pay-as-you-go).

Answer

Full control over underlying hardware

Answer

Requires dedicated IT staff for database administration

Answer

Higher initial capital expenditure

Question 10

Which TWO factors should be considered when choosing a software license?

Accepted Answer

Number of users. Option C (Number of users) is correct because software licenses are frequently priced and scoped per-seat, per-device, or per-concurrent-user, so the count of users directly determines which license tier or volume agreement is required. Option E (Cost) is correct because licensing cost is a primary procurement factor, encompassing the purchase price, subscription or maintenance fees, and total cost of ownership that must fit the organization's budget. The remaining options do not belong: brand name (A) is a marketing consideration rather than a licensing term, font style (B) and interface color (D) are cosmetic design attributes unrelated to license rights, restrictions, or pricing.

Answer

Brand name

Answer

Font style

Answer

Color of interface

Question 11

A company wants to secure its wireless network. Which of the following is the BEST practice?

Accepted Answer

Change the default administrator password. Changing the default administrator password is the best practice because default credentials are widely known and easily exploited, providing an attacker with full administrative access to the wireless access point or router. This action directly mitigates unauthorized configuration changes, which is a fundamental security measure. In contrast, the other options either weaken security or have no significant protective effect.

Answer

Broadcast the SSID

Answer

Disable MAC filtering

Answer

Use WEP encryption

Question 12

A university database includes a table named 'Students' and a table named 'Enrollments'. The 'Enrollments' table has a foreign key column 'StudentID' that references the 'StudentID' primary key in the 'Students' table. The university policy requires that when a student withdraws (i.e., their record is deleted from the 'Students' table), all of their associated enrollment records must be automatically removed to maintain data consistency. The database administrator wants to enforce this rule at the database level. Which referential action should be applied when creating the foreign key constraint on the 'Enrollments' table?

Accepted Answer

ON DELETE CASCADE. (ON DELETE CASCADE) is correct because it automatically deletes all child rows in the 'Enrollments' table when the corresponding parent row in the 'Students' table is deleted. This enforces the university policy of removing associated enrollment records upon student withdrawal, maintaining referential integrity at the database level without manual intervention.

Answer

ON DELETE SET NULL

Answer

ON DELETE NO ACTION

Answer

ON DELETE RESTRICT

Question 13

A company needs to manage and secure a fleet of employee smartphones used for work. Which technology should they implement?

Accepted Answer

Answer

DNS

Answer

NAC

Answer

VPN

Question 14

A technician is explaining the difference between volatile and non-volatile memory to a trainee. Which TWO of the following are examples of volatile memory? (Select TWO.)

Accepted Answer

DDR4 RAM. Volatile memory loses data when power is off. RAM (including DDR4 and DDR5) and cache memory (L1/L2/L3) are volatile. ROM and SSDs are non-volatile.

Answer

ROM

Answer

BIOS firmware

Answer

SSD

Question 15

A user reports that the company's customer relationship management (CRM) application is slow after a recent network upgrade. What could be the cause?

Accepted Answer

The network firewall is blocking certain CRM traffic.. A network firewall can introduce latency or block traffic if its rules are misconfigured after an upgrade. If the CRM application relies on specific ports or protocols (e.g., HTTPS on TCP 443, or a proprietary port like TCP 8080), the firewall might be inspecting, throttling, or dropping packets, causing perceived slowness. This is a common post-upgrade issue when ACLs or stateful inspection rules change.

Answer

The application has too many users.

Answer

The user's password has expired.

Answer

The user is entering data too quickly.
