FC0-U71 Timed Practice Test 3 — 10 Questions

Question 1

A help desk technician receives a call from a user who cannot connect to a network share. The user's computer shows a network icon with a red X. The technician asks the user to check the network cable connection. The user reports that the cable is securely connected. The technician then pings the default gateway from their own computer and the ping is successful. Which of the following is the NEXT step the technician should take?

10 minute time limit — choose an answer to begin.

Accepted Answer

Check the IP configuration on the user's computer. The user's computer shows a network icon with a red X, indicating a physical or data-link layer issue, but the cable is reported as securely connected. The technician successfully pings the default gateway from their own computer, proving the network infrastructure (router, switch, cabling) is functional. The next logical step is to check the IP configuration on the user's computer, as a missing or misconfigured IP address (e.g., APIPA 169.254.x.x due to DHCP failure) could prevent connectivity even with a good cable. This isolates the problem to the user's device rather than the network.

Answer

Replace the network cable

Answer

Restart the network share server

Answer

Disable the firewall on the user's computer

Question 2

Which network device converts the signal from an Internet Service Provider (ISP) into a digital signal that a home network can use?

Accepted Answer

Answer

Access point

Answer

Switch

Answer

Router

Answer

Virus

Answer

Ransomware

Answer

Worm

Question 4

Which of the following is the best practice for backing up data according to the 3-2-1 rule?

Accepted Answer

Three copies on two different media types, with one copy stored offsite. The 3-2-1 rule means at least three copies of data, on two different types of storage media, with one copy stored offsite.

Answer

Three copies on three different external hard drives stored in the same building

Answer

Two copies on the same server, one on a different server

Answer

One copy on the same drive, one on an external drive, one in the cloud

Question 5

A security analyst is explaining the difference between a threat and a vulnerability. Which statement accurately describes this difference?

Accepted Answer

A threat is a potential cause of harm, and a vulnerability is a weakness that can be exploited.. A vulnerability is a weakness, while a threat is a potential danger that exploits that weakness.

Answer

Accepted Answer

Biometric door lock. Physical security controls include measures like locks, guards, and biometric scanners to protect physical assets.

Answer

Password policy

Answer

Antivirus software

Answer

Firewall

Question 7

Which type of malware attaches to legitimate files and spreads when those files are executed?

Accepted Answer

Virus. A virus attaches itself to files or programs and replicates when the infected file is executed. Worms spread without a host file; trojans disguise as legitimate software.

Answer

Ransomware

Answer

Worm

Answer

Trojan

Question 8

Which TWO of the following are types of malware? (Select TWO)

Accepted Answer

Ransomware. Ransomware (B) is a type of malware that encrypts a victim's files or locks a system and demands payment for restoration, making it a classic malicious software category. Spyware (E) is also malware, designed to covertly monitor user activity and harvest sensitive information such as credentials or browsing habits. A firewall (A) is a security control that filters network traffic, not malware. Encryption (C) is a legitimate cryptographic technique for protecting data confidentiality, not malicious software. Phishing (D) is a social-engineering attack that tricks users into revealing information, but it is an attack method rather than a malware type.

Answer

Firewall

Answer

Encryption

Answer

Phishing

Question 9

Which data structure is best for storing a collection of key-value pairs?

Accepted Answer

Dictionary. A dictionary (also known as a hash map or associative array) is specifically designed to store key-value pairs, allowing efficient insertion, deletion, and lookup based on a unique key. In computing, this structure uses a hash function to compute an index into an array of buckets, enabling average O(1) time complexity for operations, which is ideal for scenarios like caching or configuration settings.

Answer

Queue

Answer

Array

List

Question 10

A user wants to create a backup of important files stored on a hard drive. Which type of application is most appropriate for this task?

Accepted Answer

File manager. A file manager (such as Windows File Explorer or macOS Finder) is the most appropriate application for creating a backup of important files because it provides direct access to the file system, allowing users to copy, move, and organize files between storage locations. Unlike specialized backup software, a file manager can manually duplicate files to an external drive or cloud-synced folder without additional features like scheduling or compression, but it fully supports the core task of file duplication for backup purposes.
