FC0-U71 Practice Exam 61 — 20 Questions

Question 1

A school's computer lab has 25 computers, each running a specific educational software suite. The IT department needs to update the software on all machines to the latest version. The update is a large file, and downloading it separately on each machine would consume too much bandwidth and time. The network has a server that can host the installation files locally. Which of the following is the MOST efficient method to update the software on all computers?

Choose an answer to begin — your selection is scored in the full session.

Accepted Answer

Download the update to the server and install it over the network to all computers.. It leverages a local server to host the update file, allowing all 25 computers to install the software over the local network. This approach minimizes internet bandwidth usage and speeds up the deployment by using a single download, then distributing the update via a network share or deployment tool (e.g., Group Policy, SCCM, or a simple file copy over SMB). It is the most efficient method for large-scale updates in a LAN environment.

Answer

Install the update from a single USB flash drive on each computer.

Answer

Install the software from the original installation media on each computer.

Answer

Have each computer download the update directly from the internet at different times.

Question 2

A user needs to create a document that includes a table of contents, footnotes, and a bibliography. Which TWO application types are suitable for this task? (Choose TWO.)

Accepted Answer

Desktop publishing software.. Desktop publishing software (D) is suitable because it provides advanced layout and typography controls, including automatic generation of tables of contents, footnotes, and bibliographies, making it ideal for complex documents like books or reports. Word processing software (E) is also suitable as it includes built-in tools for inserting and managing tables of contents, footnotes, and bibliographies, which are standard features in applications like Microsoft Word or Google Docs.

Answer

Presentation software.

Answer

Database software.

Answer

Spreadsheet software.

Question 3

Which THREE are valid primitive data types in most programming languages? (Choose three.)

Accepted Answer

Character. (Character) is correct because a character is a primitive data type that stores a single alphanumeric symbol, such as 'A' or '7', typically using 1 or 2 bytes depending on encoding (e.g., ASCII or Unicode). In most programming languages like Java, C, or Python, primitive types are the most basic data types provided by the language, not composed of other types.

Answer

String

Answer

Array

Question 4

Refer to the exhibit. A user sees this error when using an application. What is the most likely cause?

Accepted Answer

The application does not have permission to write to the folder.. The error message indicates the application cannot write to the specified folder. This is most commonly caused by insufficient file system permissions, such as the user account lacking Write or Modify access to the directory. Without the correct NTFS or share permissions, the application cannot create or modify files, resulting in a write failure.

Answer

Antivirus software is blocking the application.

Answer

The data file is corrupted.

Answer

The hard drive is full.

Question 5

A database table contains repeating groups of fields for multiple phone numbers per customer. Which normal form is being violated?

Accepted Answer

First Normal Form. First Normal Form (1NF) requires that each column in a table contains atomic (indivisible) values and that there are no repeating groups of columns. Storing multiple phone numbers per customer in a single row, such as Phone1, Phone2, Phone3, violates 1NF because it creates a repeating group of fields. To comply with 1NF, the phone numbers should be stored in a separate child table with one row per phone number per customer.

Answer

Second Normal Form

Answer

Third Normal Form

Answer

No violation

Question 6

Refer to the exhibit. A user cannot access the internet. What is the most likely issue based on the configuration shown?

Accepted Answer

The default gateway is missing. The exhibit shows an IP address of 192.168.1.10 with a subnet mask of 255.255.255.0, but no default gateway is configured. Without a default gateway, the device can communicate within its local subnet (192.168.1.0/24) but cannot route traffic to any external network, including the internet. The default gateway is the router's IP address that provides the next-hop path for all off-subnet traffic.

Answer

The DNS server is not configured

Answer

The IP address is invalid

Answer

The subnet mask is incorrect

Question 7

A user can access the internet and other computers on the network but cannot print to a network printer that is on the same subnet. The printer's IP is 192.168.1.100. What is the most likely cause?

Accepted Answer

The printer is powered off. If the printer is powered off, it cannot respond to print jobs, yet the user can still access the internet and other computers on the network since those services are independent of the printer. The printer's IP address (192.168.1.100) being on the same subnet means that connectivity to it relies solely on the printer being powered on and operational at Layer 2 (Ethernet) and Layer 3 (IP). A powered-off printer will not respond to ARP requests or TCP connections, causing print jobs to fail while other network functions remain unaffected.

Answer

The router is not forwarding print jobs

Answer

The user's computer has a wrong subnet mask

Answer

The printer's DNS is misconfigured

Question 8

Which THREE of the following are primary functions of a network router?

Accepted Answer

Forwarding packets based on IP addresses. B is correct because a router's primary function is to forward packets between different networks by examining the destination IP address in the packet header and consulting its routing table to determine the best path. This Layer 3 (Network Layer) operation is fundamental to routing, distinguishing it from switches that operate at Layer 2.

Answer

Providing wireless access to clients

Answer

Connecting devices within the same local network

Question 9

Based on the exhibit, which type of attack is most likely occurring?

Accepted Answer

Brute force attack. The exhibit shows repeated login attempts with different passwords (e.g., 'password1', 'password2', 'password3') against a single user account. This pattern of systematically trying many passwords to guess credentials is the hallmark of a brute force attack. Unlike a denial-of-service or phishing attack, the goal here is to gain unauthorized access by exhausting possible password combinations.

Answer

Denial-of-service attack

Answer

Phishing attack

Answer

Man-in-the-middle attack

Question 10

A hospital's IT team manages a virtualized server hosting a patient records database. The server has one physical processor with 6 cores, 32 GB of RAM, and a RAID 5 array of three 1 TB HDDs. The virtual machine (VM) running the database is configured with 2 vCPUs, 8 GB RAM, and a 500 GB virtual disk stored on the RAID array. Users report that database queries are taking much longer than usual. The host server shows CPU utilization at 20%, memory at 60%, and the disk queue length frequently stays above 5. Which of the following is the most likely cause of the performance issue?

Accepted Answer

Disk I/O bottleneck. The disk queue length consistently exceeding 5 indicates that I/O requests are waiting for the storage subsystem, which is a classic sign of a disk I/O bottleneck. The RAID 5 array of three 1 TB HDDs provides limited IOPS compared to SSDs, and the single virtual disk on this array cannot keep up with the database workload. Even though CPU and memory utilization are moderate, the high queue length shows the disks are the limiting factor.

Answer

Network bandwidth limitation

Answer

Insufficient memory

Answer

Insufficient CPU resources

Question 11

Refer to the exhibit. What does this event log entry indicate?

Accepted Answer

A power outage or unexpected shutdown occurred. The event log entry indicates a system shutdown that was not expected or planned, as shown by the 'unexpected' keyword and the event ID 41 in the System log, which corresponds to the Kernel-Power source. This typically occurs when the system loses power or crashes without a clean shutdown process, such as during a power outage or hardware failure.

Answer

A virus infected the system

Answer

A software update was installed

Answer

A scheduled restart took place

Question 12

A user cannot connect to the internet. Which step is most appropriate to start troubleshooting?

Accepted Answer

Check the network cable connection. The most appropriate first step in troubleshooting a network connectivity issue is to check the physical layer (Layer 1 of the OSI model). A loose or unplugged network cable is a common cause of connectivity loss, and verifying the cable connection is quick, non-invasive, and follows the principle of starting with the simplest possible cause before escalating to more complex solutions.

Answer

Update the graphics driver

Answer

Replace the router

Answer

Reinstall the operating system

Question 13

A database manager is designing a new table to store customer information for a retail company. The table needs to store a unique identifier for each customer, the customer's first and last name, email address, phone number, and date of birth. The manager also wants to ensure that the email address is always provided and that no two customers have the same email. Which of the following SQL constraints should be applied to the email column?

Accepted Answer

UNIQUE and NOT NULL. The email column must be both unique (to prevent duplicate email addresses) and NOT NULL (to ensure an email is always provided). The UNIQUE constraint enforces that no two rows have the same value, and NOT NULL guarantees that the column cannot be left empty. Together, they satisfy the requirement that every customer has a distinct, mandatory email address.

Answer

INDEX

Answer

FOREIGN KEY

Answer

PRIMARY KEY

Question 14

A company's email server is experiencing slow performance. The IT administrator notices high disk I/O wait times. Which component is most likely bottlenecked?

Accepted Answer

Storage. High disk I/O wait times indicate that the storage subsystem is struggling to keep up with read/write requests, causing the CPU to idle while waiting for data from the disk. This is a classic symptom of a storage bottleneck, not a CPU, network, or memory issue.

Answer

CPU

Answer

Network

Answer

RAM

Question 15

A user reports that they can access websites by IP address but not by domain name. Based on the exhibit, which of the following is the MOST likely cause?

Accepted Answer

Incorrect or unreachable DNS server. The user can access websites by IP address but not by domain name, which indicates that IP routing and connectivity are functioning correctly. The failure to resolve domain names points directly to a DNS issue, such as an incorrect or unreachable DNS server. DNS translates human-readable domain names into IP addresses; without a working DNS server, name resolution fails while direct IP access remains unaffected.

Answer

Duplicate IP address on the network

Answer

Incorrect default gateway

Answer

Incorrect subnet mask

Question 16

A small business owner wants to protect sensitive customer data stored on a laptop that is frequently used on public Wi-Fi networks. The owner is considering implementing a security control that ensures data remains confidential even if the laptop is stolen. Which of the following is the BEST control for this scenario?

Accepted Answer

Implement full-disk encryption. Full-disk encryption (FDE) protects data at rest by encrypting the entire storage volume, typically using AES-128 or AES-256. Even if the laptop is stolen, the encrypted data remains unreadable without the decryption key, ensuring confidentiality. This directly addresses the requirement for data protection after physical theft.

Answer

Use a VPN when connected to public Wi-Fi

Answer

Install antivirus software

Answer

Require a strong password for user login

Question 17

A software company uses a development model where work is divided into 2-week sprints. Each sprint begins with a planning meeting, includes daily standups, and ends with a review and retrospective. A product owner prioritizes features, and a scrum master facilitates the process. Which methodology is being used?

Accepted Answer

Scrum. Scrum is an agile framework that uses sprints, daily standups, sprint reviews, and specific roles (product owner, scrum master, development team).

Answer

Answer

Extreme Programming (XP)

Question 18

A user wants to ensure that a document cannot be edited by others. Which file property should be set?

Accepted Answer

Read-only. The read-only property prevents users from modifying or deleting the file's contents, as it restricts write access to the file. When set, any attempt to edit and save the document will result in an error unless the file is saved with a new name or the property is cleared. This is the standard file attribute used in Windows and other operating systems to enforce write protection at the file system level.
