FC0-U71 Practice Test 27 — 15 Questions

Question 1

An IT administrator is configuring a virtualized environment on a single server. The administrator needs to allocate resources to multiple virtual machines. Which THREE of the following are resources that can be allocated to a VM? (Select THREE.)

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

Accepted Answer

Virtual storage. Virtual storage (A) is a resource that can be allocated to a VM, since the hypervisor presents virtual disks (VMDK, VHDX, qcow2) backed by datastores or storage pools to each guest. vCPU (B) is correct because virtual CPUs are assigned to a VM from the host's physical cores/threads, defining its compute capacity. vRAM (D) is correct because memory is a core allocatable resource, with each VM configured for a specific amount of guest RAM. Physical GPU (C) is not a standard allocatable VM resource in a basic single-server setup; GPUs require passthrough or vGPU technologies and are not a general resource like CPU, RAM, or storage. Hypervisor license (E) is not a resource allocated to a VM; it is a software licensing concern for the host platform, not a consumable assigned to guests.

Answer

Physical GPU

Answer

Hypervisor license

Question 2

Which element of the CIA triad is primarily concerned with ensuring that data is not accessed by unauthorized individuals?

Accepted Answer

Confidentiality. Confidentiality is the CIA triad element that ensures data is only accessible to authorized individuals, typically enforced through encryption, access controls, and authentication mechanisms. It directly addresses the concern of preventing unauthorized access or disclosure. Integrity concerns data accuracy, and availability concerns uptime — neither addresses unauthorized access.

Answer

Authentication

Answer

Availability

Answer

Integrity

Question 3

Which cloud service model provides the customer with the ability to run and manage applications on a cloud infrastructure but does NOT give control over the underlying operating system?

Accepted Answer

PaaS. PaaS (Platform as a Service) provides a platform allowing customers to develop, run, and manage applications without the complexity of building and maintaining the underlying infrastructure. The customer controls the deployed applications and possibly configuration settings for the application-hosting environment, but does not manage the operating system, servers, or virtualization. This matches the question's requirement exactly.

Answer

SaaS

Answer

DaaS

Answer

IaaS

Question 4

A company stores product data in a MongoDB database. Each product document contains fields like 'name', 'price', and 'tags' (an array). What type of NoSQL database is MongoDB?

Accepted Answer

Document store. MongoDB is a document store because it stores data in flexible, JSON-like documents (BSON) where each document can have a different structure. The example product document with fields like 'name', 'price', and 'tags' (an array) is a classic document-oriented model, allowing nested data and arrays without a fixed schema. This contrasts with other NoSQL types that organize data differently.

Answer

Wide-column store

Answer

Graph database

Answer

Key-value store

Question 5

Which of the following is a best practice for creating a strong password?

Accepted Answer

Using a long passphrase that includes symbols and numbers. A long passphrase that includes symbols and numbers is considered a best practice because it increases both length and complexity, making it significantly harder for attackers to crack using brute-force or dictionary attacks. Length is the most critical factor in password strength, and adding symbols and numbers further expands the search space. This approach aligns with guidance from NIST and other security organizations, which recommend passphrases over short, complex passwords.

Answer

Using a password with 8 characters including letters and numbers

Answer

Reusing the same password across multiple sites

Answer

Using your pet's name as a password

Question 6

Which of the following is a key difference between a vulnerability and a threat in cybersecurity?

Accepted Answer

A vulnerability is a weakness, while a threat is a potential danger. A vulnerability is a weakness or flaw in a system (e.g., unpatched software, misconfiguration) that could be exploited, while a threat is any potential danger or actor that could exploit that weakness (e.g., a hacker, malware, or natural disaster). Option C correctly captures this weakness-versus-danger distinction. Understanding the difference is essential for risk assessment, since risk = threat × vulnerability × impact.

Answer

A vulnerability is a potential harm, while a threat is a weakness

Answer

A vulnerability is always present, while a threat is actively exploited

Answer

A vulnerability can be patched, but a threat cannot be mitigated

Question 7

You are the IT administrator for a small company with 50 employees. The company uses a shared network drive for project files. Employees have read/write access to all folders on the drive. Recently, a ransomware attack encrypted many files on the network drive after an employee's workstation became infected. The employee had mapped the drive as a local letter. Backups are available but restoring takes several hours. Management wants to reduce the risk of future ransomware damage to the network drive. You are considering implementing one of the following controls. Which control would be most effective in limiting the spread of ransomware to the network drive?

Accepted Answer

Implement file-level permissions so users only have write access to folders they need.. Implementing file-level permissions ensures that users only have write access to the folders they need, which limits the scope of encryption if ransomware infects a user's workstation. Since the ransomware typically propagates using the user's credentials, restricting write access prevents it from encrypting files in folders the user cannot modify. This control directly reduces the attack surface on the network drive.

Answer

Enable disk encryption on the network drive.

Answer

Install antivirus software on all workstations and schedule weekly scans.

Answer

Require all employees to use a VPN when accessing the network drive.

Question 8

Refer to the exhibit. Which of the following components would be used to physically connect the desktop computer to the network?

Accepted Answer

Switch. A switch is the correct component because it operates at Layer 2 of the OSI model, using MAC addresses to forward frames between devices on the same local area network (LAN). The desktop computer's Ethernet NIC connects via a twisted-pair cable to a switch port, which provides the physical and data-link layer connectivity required for network communication.

Answer

Laptop

Answer

Network printer

Answer

Router

Question 9

Which TWO of the following are best practices for creating and managing passwords?

Accepted Answer

Enable multi-factor authentication where available. Option C is correct because enabling multi-factor authentication (MFA) adds a second verification factor (such as a TOTP code, push approval, or hardware security key) beyond the password, so a stolen or guessed password alone is insufficient to compromise the account. Option D is correct because using a unique password for each online account prevents credential-stuffing and password-spraying attacks from spreading: a breach at one site cannot be leveraged to access other accounts. The remaining options are poor practices: sharing passwords (A) destroys individual accountability and widens the attack surface, reusing passwords every 90 days (B) still allows one breach to compromise many accounts and ignores that forced periodic rotation without cause weakens security, and writing passwords on a sticky note near the computer (E) exposes credentials to anyone with physical or visual access.

Answer

Share passwords with colleagues in the same department to improve collaboration

Answer

Reuse passwords every 90 days

Answer

Write down passwords on a sticky note and keep it near the computer

Question 10

Answer

Linking

Answer

Debugging

Question 11

A network technician is troubleshooting a slow wireless connection in a crowded office. The office uses many Wi-Fi networks and devices. Which Wi-Fi standard would be best to minimize interference and provide faster speeds?

Accepted Answer

802.11ax (Wi-Fi 6). 802.11ax (Wi-Fi 6) is the best choice because it operates on both 2.4 GHz and 5 GHz (and 6 GHz in Wi-Fi 6E) and introduces OFDMA, MU-MIMO, BSS Coloring, and Target Wake Time. BSS Coloring specifically reduces interference in dense environments by allowing overlapping BSSs to distinguish each other's frames, and OFDMA improves spectral efficiency for many simultaneous clients. These features directly address the crowded-office scenario.

Answer

802.11g

Answer

802.11n (Wi-Fi 4)

Answer

802.11ac (Wi-Fi 5)

Question 12

A company wants to implement a private network for devices within a single building. Which type of network should they use?

Accepted Answer

LAN. A LAN (Local Area Network) is the correct choice because it is designed to cover a single building or a limited geographic area such as an office, home, or campus floor. It provides high-speed connectivity among devices within that scope and is the standard classification for intra-building networks. WAN, MAN, and PAN describe larger or smaller scopes, respectively.

Answer

WAN

Answer

MAN

Answer

PAN

Question 13

A database has a table 'Orders' with columns OrderID (primary key), CustomerID, OrderDate, and TotalAmount. Which SQL statement will delete all orders placed before January 1, 2023?

Accepted Answer

DELETE FROM Orders WHERE OrderDate < '2023-01-01'. DELETE FROM Orders WHERE OrderDate < '2023-01-01' is the correct SQL syntax for removing rows that match a condition. DELETE is the standard DML statement for row-level removal, and the WHERE clause filters which orders are affected. The date literal '2023-01-01' is compared against OrderDate to remove all orders placed before that date.

Answer

DROP FROM Orders WHERE OrderDate < '2023-01-01'

Answer

DELETE OrderDate < '2023-01-01' FROM Orders

Answer

REMOVE FROM Orders WHERE OrderDate < '2023-01-01'

Question 14

Which SQL statement is used to retrieve all columns from a table named 'Customers' where the city is 'London'?

Accepted Answer

SELECT * FROM Customers WHERE city = 'London';. SELECT * FROM Customers WHERE city = 'London'; is the correct SQL statement to retrieve all columns from the Customers table where the city is London. SELECT * specifies all columns, FROM identifies the table, and WHERE filters rows based on the city condition. The semicolon terminates the statement.

Answer

RETRIEVE * FROM Customers WHERE city = 'London';

Answer

SELECT * FROM Customers HAVING city = 'London';

Answer

GET * FROM Customers WHERE city = 'London';

Question 15

Which of the following is an example of an output device?

Accepted Answer

Monitor. An output device receives processed data from a computer and presents it to the user in a human-readable or usable form. A monitor is a classic output device because it displays visual information such as text, images, and video generated by the computer's GPU. It does not send data into the computer; it only presents data outward to the user.

Answer

Scanner

Answer

Mouse

Answer

Keyboard
