VDI (Virtual Desktop Infrastructure) allows users to access a desktop environment that is running on a server in the data center rather than on the local machine. This is particularly useful for employees who need to work remotely on various devices (A), as it provides a consistent and secure environment regardless of the endpoint device. For a bank with security concerns regarding employee activity (D), VDI offers a centralized management of desktops, enhancing security by keeping sensitive data and applications within the data center and not on the local devices, thus reducing the risk of data breaches.

CompTIA A+ Core 1 Exam Objectives Section 4.2: Summarize aspects of client-side virtualization.

In laser printing, the fuser unit is responsible for bonding the toner to the paper using heat and pressure. If the toner is not sticking to the paper, resulting in illegible documents despite trying different brands of paper, it indicates a problem with the fuser unit. It might not be reaching the necessary temperature to melt the toner properly, necessitating its replacement to ensure proper printouts.

CompTIA A+ Core 1 Exam Objectives Section 3.7: Given a scenario, install and replace printer consumables.

In this scenario, running a network cable over a long distance (279ft or 85m) and sharing conduit with a large power cable requires careful consideration of electromagnetic interference (EMI) and the physical distance limitations of the cable type. Fiber optic cables are immune to electromagnetic interference and can support much longer distances than copper-based cables like Cat 5e or Cat 6 without signal degradation. This makes fiber optic the most appropriate choice for this project.

CompTIA A+ Core 1 Exam Objectives Section 3.1: Explain basic cable types and their connectors, features, and purposes.

CompTIA A+ Core 1 Exam Objectives Section 2.2: Compare and contrast common networking hardware.

Routers are designed to connect multiple networks and direct packets to their intended destinations across network segments. This makes them essential for directing packets to networks outside of the LAN, such as the internet or other remote networks.

CompTIA A+ Core 1 Exam Objectives Section 2.2: Compare and contrast common networking hardware.

Upgrading a power supply to add a GPU typically requires more wattage to accommodate the additional power demands. Although the current power supply is 380W, adding a GPU with a six-pin power connector suggests a mid-range graphics card, which would likely need a total system power supply in the range of 450W to ensure adequate power for all components, providing a good balance between capacity and safety margins.

CompTIA A+ Core 1 Exam Objectives Section 3.5: Given a scenario, install or replace the appropriate power supply.

Duplex printing allows printing on both sides of a paper, which can significantly reduce paper consumption and costs associated with buying paper. This makes duplex printing the best feature for cutting costs on consumables.

CompTIA A+ Core 1 Exam Objectives Section 3.6: Given a scenario, deploy and configure multifunction devices/printers and settings.

Liquid cooling is an effective solution for managing the high heat output that can result from overclocking a GPU. It's more efficient than air cooling methods (like larger heat sinks or fan upgrades) and can better maintain lower temperatures under load, reducing the risk of overheating.

CompTIA A+ Core 1 Exam Objectives Section 3.4: Given a scenario, install and configure motherboards, CPUs, and add-on cards.

These answers align with the CompTIA A+ certification objectives and are derived from the official CompTIA A+ Core 1 (220-1101) and Core 2 (220-1102) Exam Objectives documents.

After setting up a RAID 5 array, the next step is to make the storage space usable by the operating system. This involves partitioning the array to define how the storage space is organized and then formatting it with a file system that the operating system can understand, thus making it possible to copy files to the array. Decreasing the number of drives, rebuilding the array, or checking the hot spare status would not address the issue of the array not being ready to store files.

CompTIA A+ Core 1 Exam Objectives Section 3.3: Given a scenario, select and install storage devices.

For setting up a private network, the IP address range should be one that is reserved for private use. The range 172.16.0.0 to 172.31.255.255 falls within the set of IP addresses designated for private networks according to RFC 1918. This range is not routable on the public internet, making it ideal for a private network setup on a retail router.

CompTIA A+ Core 1 Exam Objectives Section 2.5: Given a scenario, install and configure basic wired/wireless SOHO networks.
