Question 4

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. Type 1 hypervisors run directly on hardware without a host OS, providing better performance and reliability for server workloads.

Answer

Hosted hypervisor like VirtualBox

Answer

Containerization platform like Docker

Answer

Type 2 hypervisor, such as VMware Workstation

Question 5

A network technician is troubleshooting intermittent Wi-Fi dropouts in a crowded office building. The office uses 2.4 GHz and 5 GHz dual-band access points. Users report better range but more interference on one band. Which frequency band is likely experiencing more interference?

Accepted Answer

2.4 GHz. 2.4 GHz has longer range but more interference from devices like microwaves and Bluetooth, and has fewer non-overlapping channels.

Answer

Both experience equal interference

Answer

5 GHz

Answer

Neither band experiences interference

Question 6

A user wants to upgrade their desktop's storage from a traditional hard drive to a faster drive that connects directly to the motherboard without cables. Which storage interface should they choose?

Accepted Answer

NVMe M.2. NVMe M.2 drives connect directly to the motherboard via M.2 slot, offering faster speeds than SATA SSDs.

Answer

External USB drive

Answer

SATA SSD

Answer

SATA hard drive

Question 7

A user is setting up a new wireless router at home. During configuration, they see options for Wi-Fi 5 (802.11ac) and Wi-Fi 6 (802.11ax). Which standard offers faster speeds and better performance in congested environments?

Accepted Answer

Wi-Fi 6. Wi-Fi 6 is the newer standard with higher data rates, improved efficiency, and better handling of multiple devices.

Answer

Neither affects speed

Answer

Both are identical in speed

Answer

Wi-Fi 5

Question 8

A technician is choosing expansion cards for a new workstation. The workstation will be used for high-end gaming and video editing. Which TWO cards are most essential for these tasks?

Accepted Answer

Graphics card (GPU). A dedicated GPU is essential for gaming and video editing, and a sound card provides high-quality audio.

Answer

Network interface card (NIC)

Answer

TV tuner card

Answer

USB expansion card

Question 9

A company is deploying mobile devices for its sales team. The devices need to access corporate email and calendars securely. Which THREE features are most important for managing these devices centrally?

Accepted Answer

Remote wipe capability. MDM enables remote management, remote wipe protects data if lost, and GPS tracking helps locate devices.

Answer

NFC for mobile payments

Answer

High-resolution camera

Question 10

A network administrator is redesigning a small office network with 20 computers, two servers, and three printers. The network must be reliable and easy to troubleshoot. Which TWO network topologies should the administrator consider?

Accepted Answer

Star. Star topology is most common for office networks due to easy troubleshooting and expansion. Mesh provides high reliability but is expensive; for a small office, star is practical, and mesh could be considered if high fault tolerance is needed, but the question asks for two topologies to consider. Typically, star is the best; bus and ring are outdated. However, the administrator might consider star and mesh (for critical links). But given the options, star is correct, and mesh is also a valid consideration for resilience. However, the exam expects star as primary, and perhaps hybrid? But the options: bus, ring, star, mesh, hybrid. The best two for reliability and troubleshooting are star and mesh (though mesh costly). But in ITF+ context, star is recommended; mesh is for high-availability. I'll go with star and mesh. Explanation: Star is easy to troubleshoot, mesh provides redundancy.

Answer

Hybrid

Answer

Ring

Answer

Bus

Question 11

A user wants to synchronize files across multiple devices, including an iPhone, a Windows laptop, and an Android tablet. Which TWO cloud services would be most effective for this cross-platform syncing?

Accepted Answer

OneDrive. iCloud works well across Apple devices and Windows, but not Android easily. Google Drive works on all platforms. OneDrive works on all platforms too. But the question asks for TWO. iCloud and Google Drive are cross-platform, but iCloud has limited Android support. Actually, iCloud does not sync with Android directly. Google Drive works on all. OneDrive works on all. So the best two are Google Drive and OneDrive. However, the stem includes iPhone, so iCloud is native but not Android. So the answer should be Google Drive and OneDrive. But I'll reconsider: Many users use iCloud and Google Drive. However, iCloud on Android is not as seamless. The ITF+ likely expects common cloud services: iCloud, Google Drive, OneDrive. But for cross-platform, Google Drive and OneDrive are better. I'll choose Google Drive and OneDrive. Explanation: Both work on iOS, Windows, and Android.

Answer

Bluetooth file transfer

Answer

iTunes sync

Answer

iCloud

Question 12

An IT technician is setting up a home office network. The technician needs to connect multiple devices to the internet and ensure they can communicate with each other. Which THREE devices are essential for this setup?

Accepted Answer

Modem. A modem connects to the ISP, a router routes traffic between devices and the internet, and a switch connects multiple wired devices within the LAN. A hub is outdated and not essential; a firewall is often integrated into the router.

Answer

Hub

Answer

Firewall appliance

Question 13

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?

Accepted Answer

Virtual CPU (vCPU). vCPU provides processing power, vRAM provides memory, and vHDD provides storage. vGPU is not typical for database servers, and virtual NIC is needed for network but not directly for performance of the database itself.

Answer

Virtual GPU (vGPU)

Answer

Virtual NIC

Question 14

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 ink cartridges and print heads that wear out. Toner is for laser printers. Paper is consumable but not unique to inkjet.

Answer

Drum unit

Answer

Fuser unit

Answer

Toner cartridge

Question 15

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). 4K resolution provides high detail, high refresh rate (e.g., 144Hz) ensures smooth motion, and IPS panel technology offers better color accuracy. Response time is less critical for design, and size is secondary.

Answer

Large screen size (32 inches)

Answer

Fast response time (1ms)
