FC0-U71 Practice Exam 63 — 20 Questions

Question 1

A company is setting up a new branch office. The network administrator needs to connect 20 computers and 2 network printers to the local network. The branch also needs a connection to the internet via a cable modem. The administrator has a 24-port switch and a wireless router. The cable modem is already provided by the ISP. Which configuration should the administrator use?

Accepted Answer

Connect the cable modem to the wireless router's WAN port, then connect the switch to one of the router's LAN ports, and connect all devices to the switch. The wireless router must be placed between the cable modem and the switch to perform Network Address Translation (NAT) and routing. The cable modem connects to the router's WAN port, which obtains a public IP from the ISP. The router then provides private IP addresses via DHCP to the switch and all connected devices, enabling internet access for the 20 computers and 2 printers through a single public IP.

Answer

Connect the cable modem to the switch, and then connect the wireless router to the switch using its WAN port

Answer

Connect the cable modem directly to the switch, then connect all devices to the switch

Answer

Connect the cable modem to one computer, then bridge that computer's network connection to the switch

Question 2

Which security best practice is being demonstrated?

Accepted Answer

Using a private DNS server. Using a private DNS server enhances security by allowing an organization to control DNS resolution internally, preventing external interception or manipulation of DNS queries. This practice helps protect against DNS spoofing and ensures that internal resources are resolved using trusted, local records rather than relying on potentially compromised public DNS servers.

Answer

Using a public DNS server

Answer

Using a static IP address

Answer

Using a dynamic IP address

Question 3

Match each operating system to its common environment.

Accepted Answer

Windows: Personal computers and gaming. Common environments: Windows (personal computing/gaming), Linux (servers/development), macOS (creative work). Android is for mobile, Chrome OS for web-based tasks.

Answer

Android: Servers and development

Answer

Chrome OS: Personal computers and gaming

Question 4

A user wants to install a 32-bit application on a 64-bit version of Windows 10. The application's installer runs but displays an error message stating that the application requires a 32-bit operating system. Which of the following is the most likely cause?

Accepted Answer

The application is designed to only run on a 32-bit operating system.. The error message explicitly states that the application requires a 32-bit operating system. This indicates that the application's code is written to only run on a 32-bit OS, often due to reliance on 16-bit components or kernel-mode drivers that are not supported in the 64-bit Windows environment. Windows 10 64-bit includes WOW64 (Windows 32-bit on Windows 64-bit) to run most 32-bit applications, but some legacy applications are hard-coded to check for a 32-bit OS and will refuse to run on 64-bit.

Answer

The user needs to run the installer in compatibility mode for 32-bit.

Answer

The installer is corrupted and needs to be re-downloaded.

Answer

The application requires drivers that are not available for 64-bit.

Question 5

Answer

Smoke testing

Answer

Alpha testing

Question 7

Which THREE of the following are common methods for securing a wireless network?

Accepted Answer

Implementing MAC address filtering. MAC address filtering is a common method for securing a wireless network because it allows the administrator to create an allowlist of specific MAC addresses that are permitted to connect to the access point. This prevents unauthorized devices from associating with the network, even if they know the SSID and password. However, it is not foolproof, as MAC addresses can be spoofed using tools like `macchanger`.

Answer

Enabling WEP encryption

Answer

Changing the default IP address range

Question 8

Drag and drop the steps to open the Task Manager in Windows 10 into the correct order.

Accepted Answer

One common way to open it in Windows 10 is to press Windows key + R to open the Run dialog, type 'taskmgr', and press Enter. The correct order ensures the dialog is open before entering the command and executing it.

Answer

Type 'taskmgr', then press Windows key + R, then press Enter

Answer

Press Windows key + R, then press Enter, then type 'taskmgr'

Answer

Press Enter, then press Windows key + R, then type 'taskmgr'

Question 9

Which SQL statement would you use to retrieve the names of all products with a price greater than $50 from a table named 'Products'?

Accepted Answer

SELECT Name FROM Products WHERE Price > 50. The SELECT statement is used to query data; the WHERE clause filters rows. The correct syntax is SELECT column FROM table WHERE condition.

Answer

SELECT Name FROM Products HAVING Price > 50

Answer

SELECT * FROM Products IF Price > 50

Answer

GET Name FROM Products WHERE Price > 50

Question 10

A computer has 8 GB of RAM. If the operating system and applications are using 3.2 GB, how much RAM is available for other processes?

Answer

11.2 GB

Answer

5.8 GB

Answer

3.2 GB

Question 11

A technician is explaining the difference between lossy and lossless compression to a colleague. Which of the following file formats uses lossy compression?

Question 12

A user notices their computer is running slowly and has many applications open. Which TWO hardware components are most likely to impact the speed at which multiple applications can run simultaneously? (Select TWO).

Question 18

A user reports that they cannot print to a network printer. Other users can print to the same printer. Which of the following should the technician check FIRST?

Accepted Answer

The printer driver on the user's computer. Since other users can print to the same network printer, the printer itself, its network connectivity, and its IP address are all functioning correctly. The issue is isolated to the single user's computer, making the printer driver on that machine the most likely cause. A corrupted, missing, or incorrect driver would prevent that specific user from sending print jobs while others remain unaffected.

Answer

The printer's IP address

Answer

The network switch port

Answer

The printer's power cable

Question 19

A software developer is writing a script that needs to run a set of instructions repeatedly until a condition is met. Which programming construct should be used?

Accepted Answer

While loop. A while loop is the correct construct because it repeatedly executes a block of code as long as a specified condition remains true. This is ideal for scenarios where the number of iterations is not known in advance and depends on a dynamic condition, such as waiting for a file to appear or a network response.

Answer

For loop

Answer

If-else statement

Answer

Function definition
