FC0-U71 Infrastructure Practice Test 2 — 15 Questions

Question 1

A database administrator is configuring a virtual machine (VM) to run a high-performance database. The hypervisor is VMware ESXi. Which THREE resources should the administrator allocate to the VM to ensure optimal performance?

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

Accepted Answer

Virtual CPU (vCPU). Option A, Virtual CPU (vCPU), is correct because a high-performance database needs dedicated processing capacity, and allocating the appropriate number of vCPUs directly determines the VM's compute throughput for query execution and transaction processing. Option C, Virtual RAM (vRAM), is correct because databases rely heavily on memory for buffer pools, caching, and sorting operations, so sufficient vRAM minimizes disk I/O and dramatically improves performance. Option D, Virtual hard disk (vHDD), is correct because the database's data files, log files, and tempdb must reside on storage, and the vHDD's size, type (e.g., thick-provisioned, paravirtual SCSI), and datastore backing directly affect I/O latency and throughput. Option B, Virtual GPU (vGPU), is not appropriate because databases are CPU-, memory-, and storage-bound workloads that do not benefit from GPU acceleration in typical configurations. Option E, Virtual NIC, while necessary for network connectivity, is not one of the three primary resource allocations that determine database performance and is not marked correct.

Answer

Virtual GPU (vGPU)

Answer

Virtual NIC

Question 2

A user is printing a large document at home. The printer is an inkjet model. Which TWO consumables will need to be replaced periodically?

Accepted Answer

Print head. Inkjet printers use liquid ink, so the ink cartridge (E) is a consumable that must be replaced periodically as the ink is depleted during printing. The print head (D) is also a periodic replacement item on many inkjet models because it can clog, wear out, or become permanently damaged, and on some printers it is integrated with the ink cartridge while on others it is a separate user-replaceable assembly. Drum units (A) and fuser units (B) are electrophotographic laser-printer components, not inkjet consumables, and toner cartridges (C) contain dry toner powder used by laser printers rather than the liquid ink an inkjet requires.

Answer

Drum unit

Answer

Fuser unit

Answer

Toner cartridge

Question 3

A technician is selecting a monitor for a graphic designer. The designer needs accurate color representation and smooth motion. Which THREE specifications are most important to consider?

Accepted Answer

High refresh rate (144Hz). Option A (High refresh rate, 144Hz) is correct because a 144Hz refresh rate refreshes the screen 144 times per second, which produces noticeably smoother motion for animations, video editing, and scrolling than a standard 60Hz panel. Option B (IPS panel technology) is correct because IPS panels deliver superior color accuracy, wider viewing angles, and more consistent color reproduction than TN panels, which is essential for a graphic designer needing accurate color representation. Option C (4K resolution, 3840x2160) is correct because the higher pixel density provides sharper detail and more on-screen workspace, allowing designers to view fine image details and full-resolution assets accurately. Option D (Large screen size, 32 inches) is not among the marked answers because screen size alone does not determine color accuracy or motion smoothness, and a smaller high-quality panel can outperform a larger inferior one. Option E (Fast response time, 1ms) is not among the marked answers because 1ms response times are typically a TN-panel gaming feature, and while low response time reduces ghosting, it is less critical here than color accuracy and refresh rate for a designer's workflow.

Answer

Large screen size (32 inches)

Answer

Fast response time (1ms)

Question 4

A technician is setting up a small office network with five workstations and a file server. Which TWO of the following are essential hardware components for this network to function? (Select TWO).

Accepted Answer

Switch. A switch (A) is essential because it provides the central wired connectivity for the five workstations and file server, forwarding frames by MAC address within the local LAN. A router (B) is essential because it connects this local network to other networks (such as the internet or another subnet) and performs Layer 3 routing between them. A hub (C) is not required since it is an obsolete, half-duplex shared-medium device that a switch replaces. A firewall (D) is a security appliance, not a functional requirement for basic LAN communication. A modem (E) is only needed for a specific WAN medium (e.g., cable/DSL), not for the internal network to function.

Answer

Hub

Answer

Firewall

Answer

Modem

Question 5

A technician is configuring a SOHO router for a small business. The owner wants wireless devices to be able to connect without manually entering long, complex passwords, while still keeping the network secure. Which of the following should the technician enable to meet this requirement?

Accepted Answer

WPS. WPS is designed to simplify connecting devices to a wireless network without manually entering a long password, which matches the owner's request. It maintains security by using the existing encryption protocol. The other options either do not simplify the connection process or are unrelated to wireless authentication. Therefore, WPS is the appropriate feature to enable.

Answer

SSID broadcast disabled

Answer

Port forwarding

Answer

MAC filtering

Question 6

A small business is setting up a new wireless network. The office has many walls and the network must penetrate them effectively while providing good range. Which wireless standard and frequency band should the technician choose?

Accepted Answer

802.11n on the 2.4 GHz band. The 2.4 GHz band is better at penetrating walls and providing broader coverage, which is essential in an office with many walls. 802.11n is a reliable standard that supports 2.4 GHz and offers decent speeds for a small business. Other options pair higher frequency bands that reduce range or an invalid standard-band combination.

Answer

802.11g on the 5 GHz band

Answer

802.11ax on the 5 GHz band

Answer

802.11ac on the 5 GHz band

Question 7

A technician is configuring a new laptop for a user. The user needs to connect to a projector for presentations and also requires a wired network connection for secure data transfers. The laptop has only USB-C ports available. Which of the following should the technician use to meet these requirements?

Accepted Answer

A USB-C to HDMI adapter and a USB-C to Ethernet adapter. Using separate USB-C to HDMI and USB-C to Ethernet adapters directly addresses both needs: video output for the projector and a wired network connection. This approach is simple and avoids potential compatibility issues with docking stations. The other options either lack Ethernet or use incorrect connectors.

Answer

A USB-C docking station with HDMI and Ethernet ports

Answer

A USB-C to VGA adapter and a USB-C to USB-A adapter

Answer

A USB-C to DisplayPort adapter and a USB-C to RJ-11 adapter

Question 8

A technician is upgrading a desktop computer's storage to improve performance. The computer currently has a traditional hard disk drive (HDD) and supports SATA III. The technician wants to install a solid-state drive (SSD) that will provide faster boot times and application loading. Which TWO of the following factors will most directly affect the performance improvement? (Choose two.)

Accepted Answer

The computer's SATA version (e.g., SATA II vs. SATA III). The interface type and the SATA version are the two factors that most directly determine the maximum speed achievable from an SSD upgrade. The interface sets the protocol and potential bandwidth, while the SATA version caps the actual throughput. Other factors like capacity, form factor, and RAM do not directly limit the performance gain from switching to an SSD.

Answer

The amount of RAM installed in the computer

Answer

The SSD's form factor (2.5-inch vs. M.2)

Answer

The SSD's storage capacity

Question 9

A technician is configuring a new all-in-one printer for a small office. Users need to print from Windows laptops, macOS desktops, and mobile phones on the same wireless network. Which of the following should the technician enable to allow printing without installing vendor-specific drivers on each device?

Accepted Answer

Internet Printing Protocol (IPP) with driverless support. IPP with driverless extensions, often branded as IPP Everywhere or Mopria, lets clients discover the printer and obtain its capabilities automatically. Windows, macOS, Linux, iOS, and Android all support this model, so users can print without installing vendor-specific drivers. The other protocols are either tied to one platform, legacy, or designed for file sharing rather than driverless printing.

Answer

Server Message Block (SMB) direct printing

Answer

Line Printer Daemon (LPD)

Answer

AirPrint

Question 10

A small business uses a cloud-based file sharing service. The owner wants to ensure that only authorized employees can access sensitive files, even if an employee's laptop is stolen and the thief tries to access the files offline. Which of the following should be implemented?

Accepted Answer

Full-disk encryption. Full-disk encryption ensures that all data on the laptop's drive is encrypted, making it inaccessible without proper authentication. This protects cached cloud files even when the device is offline and stolen. MFA, file-level permissions, and VPNs address other aspects of security but do not prevent offline access to local copies. Thus, FDE is the correct solution.

Answer

Multi-factor authentication

Answer

VPN connection

Answer

File-level permissions

Question 11

A technician is setting up a new desktop computer for a user. The user needs to connect a monitor that supports both digital video and audio over a single cable. Which of the following ports should the technician use?

Accepted Answer

HDMI. HDMI is designed to carry both digital video and audio over a single cable, making it suitable for a monitor that requires both. VGA and DVI do not support audio in standard implementations. While DisplayPort also supports audio and video, HDMI is the more common and direct answer for this scenario. Therefore, HDMI is the correct port.

Answer

DVI

Answer

DisplayPort

Answer

VGA

Question 12

A technician is upgrading a desktop computer's memory. Which component would the technician most likely replace to improve system performance using dual-channel architecture?

Accepted Answer

RAM. RAM is correct because dual-channel architecture requires installing memory modules in matched pairs in specific slots on the motherboard, which doubles the memory bandwidth. Upgrading RAM by adding a second matching module enables dual-channel operation, improving system performance for memory-intensive tasks. The question asks which component to replace to improve performance using dual-channel architecture, and RAM is the only component that directly relates to dual-channel memory.

Answer

GPU

Answer

Storage drive

Answer

CPU

Question 13

A company issues smartphones to employees and needs to enforce security policies such as remote wipe and mandatory encryption. Which technology should the IT department implement?

Accepted Answer

MDM. Mobile Device Management (MDM) is the correct technology because it provides centralized policy enforcement for smartphones, including remote wipe, mandatory encryption, passcode requirements, and app management. MDM agents on the device check in with the MDM server (e.g., Intune, Jamf, Workspace ONE) and apply configuration profiles that enforce these controls. This directly matches the stated requirements.

Answer

Antivirus software

Answer

VPN

Answer

Firewall

Question 14

A network administrator is setting up a small office network with 20 computers. The network must be easy to troubleshoot and resilient to a single cable failure affecting only one device. Which topology is most appropriate?

Accepted Answer

Star. Star topology connects each device to a central switch. If one cable fails, only that device is affected, making it easy to troubleshoot. It is the most common for modern networks.

Answer

Ring

Answer

Bus

Answer

Mesh

Question 15

A user's laptop has a SATA SSD, and they want to upgrade to a faster storage solution. Which interface technology would provide the most significant performance improvement?

Accepted Answer

NVMe M.2. NVMe M.2 provides the most significant performance improvement because it communicates over PCIe lanes rather than the SATA bus, bypassing the AHCI controller and its ~600 MB/s ceiling. NVMe drives routinely exceed 3,000 MB/s and support deep parallel command queues (up to 64K queues with 64K commands each), dramatically reducing latency.

Answer

Hybrid drive (SSHD)

Answer

External USB 3.0 SSD

Answer

SATA M.2
