FC0-U71 Practice Test 32 — 15 Questions

Question 1

A user needs to edit a PDF file that was received as an attachment. What type of application is required?

Accepted Answer

A PDF editor.. A PDF editor is specifically designed to modify the content, structure, and metadata of PDF files, such as adding text, images, or annotations. Unlike a viewer, a PDF editor provides the necessary tools to edit the file directly, which is required when a user needs to make changes to a received PDF attachment.

Answer

A video player.

Answer

A web browser.

Answer

An image editing application.

Question 2

A network administrator wants to restrict access to the wireless network to only approved devices. Which security feature should be enabled on the access point?

Accepted Answer

MAC filtering. MAC filtering allows the access point to permit or deny network access based on the device's MAC address, which is a unique hardware identifier. By creating an allowlist of approved MAC addresses, the administrator can restrict the wireless network to only those devices. This directly addresses the requirement to limit access to approved devices.

Answer

Firewall rules

Answer

Disable SSID broadcast

Answer

WPA2 encryption

Question 3

Which file system is commonly used on external USB drives for compatibility between Windows and macOS?

Accepted Answer

FAT32. FAT32 is the correct answer because it is natively supported by both Windows and macOS for read and write operations, making it the most compatible file system for external USB drives that need to be used across both platforms. Unlike NTFS (which macOS can only read by default) and APFS (which Windows does not natively support), FAT32 has been a universal standard for cross-platform storage since the 1990s, though it has a 4 GB maximum file size limit.

Answer

APFS

Answer

ext4

Answer

NTFS

Question 4

A company needs to connect two separate local area networks (LANs) in different buildings. Which device is required to route traffic between the networks?

Accepted Answer

Router. A router is required to connect two separate LANs because it operates at Layer 3 (Network layer) of the OSI model and uses IP addresses to make forwarding decisions. Unlike switches or bridges, routers can examine the destination IP address, consult a routing table, and forward packets between different subnets or networks, even if they use different data link layer technologies.

Answer

Hub

Answer

Switch

Answer

Bridge

Question 5

A small business needs to share documents among employees and allow real-time collaboration. Which type of application is best suited?

Accepted Answer

Implementing a cloud-based productivity suite.. A cloud-based productivity suite (e.g., Microsoft 365, Google Workspace) stores documents on remote servers and provides real-time co-authoring, version history, and simultaneous editing via web or client applications. This directly meets the requirement for sharing documents and enabling real-time collaboration without the overhead of manual file distribution.

Answer

Using email to send attachments back and forth.

Answer

Using a web browser to access public documents.

Answer

Installing a local office suite on each workstation.

Question 6

A user reports that a program does not start when double-clicking. The technician checks that the computer meets the minimum requirements. Which concept is being applied?

Accepted Answer

System requirements. System requirements define the minimum hardware and software specifications needed for a program to run correctly. By checking that the computer meets these requirements, the technician is verifying compatibility before troubleshooting other issues. This directly applies the concept of system requirements, which include CPU speed, RAM, disk space, and OS version.

Answer

Virtualization

Answer

File compression

Answer

Encryption

Question 7

A technician is troubleshooting a user's inability to access the internet. The user can ping the default gateway but cannot ping external websites. What is the most likely issue?

Accepted Answer

DNS server is not configured or is unreachable. The user can ping the default gateway, which confirms that the local network configuration (IP address, subnet mask, and gateway) is correct and that Layer 3 connectivity to the router is working. However, pinging external websites fails because the DNS server is not configured or unreachable, preventing the resolution of domain names to IP addresses. This is a classic symptom: internal connectivity works, but name resolution fails.

Answer

Firewall is blocking all outbound traffic

Answer

Default gateway is down

Answer

IP address is misconfigured

Question 8

Which type of computer memory loses its data when the power is turned off?

Accepted Answer

RAM. RAM (Random Access Memory) is volatile memory, meaning it requires continuous electrical power to retain data. When the power is turned off, the electrical charges in the memory cells dissipate, causing all stored data to be lost. This is why RAM is used for temporary storage of actively running programs and data.

Answer

HDD

Answer

ROM

Answer

SSD

Question 9

A user reports that their computer is slow when running multiple applications simultaneously. Which component upgrade would best improve performance?

Accepted Answer

RAM. When multiple applications run simultaneously, the operating system uses RAM to store active data for quick access. Insufficient RAM forces the system to rely on the hard drive as virtual memory (paging), which is dramatically slower. Upgrading RAM reduces this paging activity, improving multitasking performance.

Answer

Video card

Answer

CPU

Answer

Hard drive

Question 10

A technician is troubleshooting a computer that won't boot. The system emits a series of beeps. What is the best resource to interpret the beep codes?

Accepted Answer

The motherboard manual. The motherboard manual is the best resource because it contains the specific beep code patterns defined by the BIOS manufacturer for that exact motherboard model. Beep codes are generated by the BIOS during Power-On Self-Test (POST) and vary between BIOS vendors (e.g., AMI, Award, Phoenix), so the motherboard manual provides the authoritative mapping of beep sequences to hardware faults.

Answer

The BIOS manufacturer's website

Answer

The computer case documentation

Answer

The operating system help

Question 11

A small office has five computers connected to a switch, which is connected to a router that provides internet access. The office uses a single printer connected to one computer and shared over the network. The router has built-in DHCP and assigns IP addresses in the 192.168.0.0/24 range. Recently, the office manager added a wireless access point (WAP) to allow guests to access the internet. The WAP is connected to the switch and configured with its own DHCP server handing out addresses in the 192.168.1.0/24 range. The manager notices that some office computers are unable to access the shared printer, while others can. The computers that cannot access the printer have IP addresses in the 192.168.1.0/24 range. The printer's IP address is 192.168.0.50. What is the most likely cause of the issue?

Accepted Answer

The computers with IP addresses in the 192.168.1.0/24 range are on a different subnet than the printer.. The computers with IP addresses in the 192.168.1.0/24 range are on a different subnet than the printer, which has an IP address of 192.168.0.50. Without a router configured to route traffic between these two subnets, devices on the 192.168.1.0/24 network cannot communicate with devices on the 192.168.0.0/24 network. Since the WAP is acting as a separate DHCP server and is not routing between the subnets, the printer remains unreachable from the guest network.

Answer

The WAP's DHCP server is malfunctioning.

Answer

The switch port for the printer is faulty.

Answer

The printer is not powered on.

Question 12

Refer to the exhibit. A user is unable to access the internet but can ping the default gateway. Based on the exhibit, what is the most likely cause?

Accepted Answer

Incorrect DNS server. The user can ping the default gateway, which confirms that Layer 3 connectivity to the local network is working and that the firewall is not blocking ICMP traffic. However, the inability to access the internet (by name or IP) while local connectivity works points to a failure in name resolution. An incorrect DNS server address prevents the client from resolving domain names to IP addresses, which is the most likely cause given the symptoms.

Answer

Firewall blocking traffic

Answer

Duplicate IP address

Answer

Incorrect subnet mask

Question 13

Refer to the exhibit. A user is able to browse the internet using the Ethernet connection but not the Wi-Fi. What is the most likely cause?

Accepted Answer

The Wi-Fi adapter is not connected to any network. The exhibit shows that the Ethernet interface has an IP address (192.168.1.114) and is connected to the internet, while the Wi-Fi interface shows 'Not connected' with no IP address assigned. Since the user can browse the internet via Ethernet but not Wi-Fi, the most likely cause is that the Wi-Fi adapter is not connected to any network, meaning it has not associated with a wireless SSID or obtained an IP address via DHCP.

Answer

The Wi-Fi adapter is disabled

Answer

The DNS suffix is missing

Answer

The default gateway is incorrect

Question 14

A computer has 8 GB of RAM installed, but the operating system reports only 7.9 GB usable. What is the most likely reason for this discrepancy?

Accepted Answer

Some RAM is reserved for hardware devices. The most likely reason is that some RAM is reserved for hardware devices. This is a standard behavior where system resources, such as memory-mapped I/O (MMIO), are allocated to hardware components like the GPU, network adapters, and PCIe devices. This reservation reduces the total usable RAM reported by the operating system, even though 8 GB is physically installed.

Answer

The operating system itself uses too much RAM

Answer

The operating system is 32-bit

Answer

The RAM is not installed in dual-channel mode

Question 15

An IT department is planning a new server deployment. They need to ensure that if one server fails, another can take over with minimal downtime. Which concept describes this requirement?

Accepted Answer

Fault tolerance. The requirement describes a system where a secondary server automatically takes over with minimal downtime upon failure of the primary server. This is the definition of fault tolerance, which uses redundant components (e.g., dual power supplies, RAID, or clustered servers) to ensure continuous operation without interruption. High availability (option C) is related but focuses on maximizing uptime through redundancy and failover, whereas fault tolerance specifically aims for zero or near-zero downtime by masking failures completely.

Answer

Disaster recovery

Answer

Scalability

Answer

High availability
