FC0-U71 Practice Test 30 — 15 Questions

Question 1

Which TWO of the following are advantages of server virtualization? (Select TWO.)

Accepted Answer

Easier backup and recovery using snapshots. Server virtualization allows administrators to take snapshots of virtual machines (VMs) at a specific point in time. These snapshots capture the entire VM state, including disk, memory, and power state, enabling quick and consistent backup and recovery without the complexity of traditional physical server backups.

Answer

Increased security by isolating VMs

Answer

Eliminates the need for operating system licenses

Answer

Improved performance over physical servers

Question 2

An IT administrator is setting up a virtualization server to run multiple operating systems. The server will host critical business applications and requires maximum performance and reliability. Which type of hypervisor should the administrator choose?

Accepted Answer

Type 1 hypervisor, such as VMware ESXi. A Type 1 (bare-metal) hypervisor like VMware ESXi runs directly on the host hardware without an underlying OS, giving it direct access to CPU, memory, and I/O resources. This architecture delivers the lowest virtualization overhead, highest performance, and best reliability — critical for hosting business-critical applications. Type 1 hypervisors also offer advanced features like vMotion, HA, and resource pools that enterprises rely on.

Answer

Hosted hypervisor like VirtualBox

Answer

Containerization platform like Docker

Answer

Type 2 hypervisor, such as VMware Workstation

Question 3

During the SDLC, testing is performed at different levels. Which TWO of the following are recognized levels of testing? (Select TWO.)

Accepted Answer

Integration testing. Integration testing (C) is a recognized level of testing in the SDLC, sitting between unit and system testing, where individual modules are combined and tested as a group to verify interfaces and interactions between components. Unit testing (D) is also a recognized level, focusing on verifying the smallest testable parts of an application, such as individual functions or methods, in isolation. These two are standard levels in the classic testing hierarchy (unit, integration, system, acceptance). Maintenance (A) is an SDLC phase that follows deployment, not a testing level. Code review (B) is a static verification technique or peer-review activity, not a defined test level. Deployment (E) is a release/implementation phase, not a testing level.

Answer

Maintenance

Answer

Code review

Answer

Deployment

Question 4

Which TWO of the following are types of optical disc storage? (Select exactly two.)

Accepted Answer

DVD. DVD (Digital Versatile Disc) is a type of optical disc storage that uses a laser to read and write data on a reflective plastic disc. It is a standard optical media format, distinct from magnetic or solid-state storage technologies.

Answer

SSD

Answer

HDD

Answer

Flash drive

Question 5

A cloud database service is being considered for a startup to avoid hardware maintenance and allow automatic scaling. Which type of service is this?

Accepted Answer

Database as a Service (DBaaS). DBaaS (Database as a Service) is the correct answer because it specifically describes a managed cloud service where the provider handles database engine installation, patching, backups, replication, and scaling, while the customer simply consumes the database. The scenario explicitly mentions avoiding hardware maintenance and enabling automatic scaling of a database — the defining characteristics of DBaaS. DBaaS is a specialized subset of PaaS focused on database workloads.

Answer

Software as a Service (SaaS)

Answer

Infrastructure as a Service (IaaS)

Answer

Platform as a Service (PaaS)

Question 6

A technician is selecting a storage solution for a home server that requires fast access speeds and redundancy against a single drive failure. Which TWO technologies should be considered?

Accepted Answer

SSD. SSD (Solid State Drive) provides fast access speeds due to its use of NAND flash memory, which eliminates mechanical seek times and rotational latency found in HDDs. This makes it ideal for a home server requiring rapid data retrieval. RAID 1 (mirroring) writes identical data to two drives, offering redundancy against a single drive failure by allowing the system to continue operating if one drive fails.

Answer

Cloud storage

Answer

HDD

Answer

RAID 0

Question 7

A junior developer is creating a script to generate reports for each of 10 departments. The script should run the report generation code exactly 10 times. Which control structure should be used?

Accepted Answer

for loop. A `for` loop is the correct control structure when the number of iterations is known in advance, such as iterating exactly 10 times over a list of departments. It provides a concise way to repeat a block of code a fixed number of times.

Answer

while loop

Answer

if-else

Answer

switch

Question 8

A company is setting up a new branch office. The network administrator needs to choose a wireless standard and a frequency band. Which TWO of the following options would provide the fastest speeds and least interference? (Select TWO.)

Accepted Answer

5GHz. Option A (5GHz) is correct because the 5GHz band offers more non-overlapping channels and is far less congested than 2.4GHz, which directly reduces interference in a branch office environment. Option C (802.11ax) is correct because Wi-Fi 6 (802.11ax) delivers the highest throughput and best spectral efficiency of the listed standards, using OFDMA, MU-MIMO, and 1024-QAM to provide the fastest speeds. Option B (2.4GHz) is not selected because it is heavily congested by neighboring networks, Bluetooth, and microwaves, causing more interference and lower speeds. Option D (802.11ac) is not selected because, while fast, it is an older Wi-Fi 5 standard that is slower and less efficient than 802.11ax. Option E (Bluetooth) is not selected because it is a short-range personal area network technology with very low throughput, not a WLAN standard for branch office connectivity.

Answer

2.4GHz

Answer

802.11ac

Answer

Bluetooth

Question 9

Which of the following is an example of system software?

Accepted Answer

Linux operating system. System software includes the operating system and utilities that manage hardware. Linux is an operating system, hence system software. Word processor, web browser, and spreadsheet are application software.

Answer

Spreadsheet

Answer

Web browser

Answer

Word processor

Question 10

Which THREE of the following are characteristics of a relational database?

Accepted Answer

Data is stored in tables with rows and columns. Option B is correct because a relational database organizes data into relations (tables) composed of tuples (rows) and attributes (columns), which is the defining structural characteristic of the relational model. Option C is correct because relational databases are queried and manipulated using SQL, the standard declarative language for defining schemas (DDL) and retrieving/modifying data (DML). Option E is correct because referential integrity is enforced through foreign keys, which constrain a column's values to match primary key values in a referenced table, preventing orphaned records. Option A does not belong because schema-less, flexible design describes NoSQL databases such as MongoDB, not relational systems, which require a predefined schema. Option D does not belong because a document-based JSON model is characteristic of document stores like CouchDB or MongoDB, not relational databases, which use normalized tables rather than embedded documents.

Answer

Schema-less design allows flexible data structures

Answer

Uses a document-based model like JSON

Question 11

Which of the following best describes the principle of least privilege?

Accepted Answer

Users should have the minimum permissions needed to do their job. The principle of least privilege (PoLP) states that a user, process, or system should be granted only the minimum access rights necessary to perform its legitimate function, and nothing more. Option B captures this exactly: minimum permissions needed to do the job. This limits the blast radius of compromised accounts, insider misuse, and accidental misconfiguration, and is a foundational control in frameworks like NIST SP 800-53 AC-6 and CIS Controls.

Answer

Users should have all permissions by default

Answer

Users should use multi-factor authentication

Answer

Users should change passwords every 30 days

Question 12

A university database includes tables: 'Professors' (ProfessorID, Name, Department) and 'Courses' (CourseID, Title, ProfessorID). Which THREE statements about this design are correct?

Accepted Answer

The primary key of Professors is ProfessorID.. Option B is correct because ProfessorID uniquely identifies each row in the Professors table, making it the natural primary key. Option D is correct because Courses.ProfessorID stores the value of the Professors primary key, so it is a foreign key referencing Professors.ProfessorID, enforcing referential integrity between the two tables. Option E is correct because a single professor's ProfessorID can appear in many Courses rows, so one professor can be associated with multiple courses. Option A is wrong because CourseID belongs to the Courses table, not Professors. Option C is wrong because the design is one-to-many: each course has one ProfessorID, so it is not many-to-many.

Answer

The primary key of Professors is CourseID.

Answer

The relationship between Professors and Courses is many-to-many.

Question 13

A developer is troubleshooting an issue where a user can list the files in a shared folder but cannot download any of them. Based on the exhibit, what is the most likely cause?

Accepted Answer

The Deny statement on read explicitly denies file retrieval.. The exhibit shows an explicit Deny statement for read access, which overrides any Allow statements due to access control evaluation logic. Even if the user has list permission, the Deny on read prevents downloading files. This is the most likely cause because Deny statements are absolute and cannot be overridden by Allow statements.

Answer

The user lacks permissions to list the folder.

Answer

The Allow statement on list also allows downloads.

Answer

The policy is malformed and causes an error.

Question 14

A developer is debugging a program that unexpectedly crashes. Which TWO tools or techniques are commonly used to identify the cause of the crash? (Select the two correct answers.)

Accepted Answer

Breakpoints. Breakpoints (C) are correct because they let a developer pause program execution at a specific line or condition, inspect variables, call stack, and memory state at the moment before the crash, which directly reveals the faulty logic or invalid value causing the failure. Logging (D) is correct because strategically placed log statements (or a logging framework) record runtime events, error messages, and stack traces leading up to the crash, allowing post-mortem analysis of the sequence of operations that triggered it. Code compilation (A) only translates source into executable code and would surface syntax or type errors at build time, not the runtime cause of a crash. Refactoring (B) restructures existing code to improve readability or design without diagnosing the crash, and code review (E) is a static, human inspection of source that may catch defects but does not observe the program's actual runtime behavior during the crash.

Answer

Code compilation

Answer

Refactoring

Answer

Code review

Question 15

What is the primary purpose of a network firewall?

Accepted Answer

To block unauthorized network traffic based on rules. A network firewall's primary purpose is to control incoming and outgoing network traffic by comparing packets against a set of predefined security rules. It acts as a barrier between trusted internal networks and untrusted external networks (like the internet), allowing or denying traffic based on criteria such as IP addresses, ports, and protocols. This rule-based filtering is the core function that distinguishes a firewall from other security tools.

Answer

To prevent malware infections by scanning files

Answer

To encrypt data transmitted over the network

Answer

To provide wireless network access
