Question 1
A VM was set up to deny access to the host computer and any network resources. Which of the following describes this scenario?
Answer : A
A sandbox is an isolated environment created for testing or running code without affecting the host system or other network resources. In this scenario, the virtual machine (VM) is set up to deny access to the host computer and any network resources, effectively creating a contained and secure space where actions within the VM do not impact the rest of the system or network. This is a key feature of sandbox environments used for testing and security purposes.
Question 2
A user's computer frequently freezes and requires multiple hard restarts to recover functionality. A technician confirms the hardware components have not been recently upgraded or replaced. Which of the following should the technician do first to troubleshoot the issue?
Answer : C
When a computer frequently freezes and requires hard restarts, the first step a technician should take, especially when hardware components have not been recently changed, is to read the event logs. Event logs can provide critical insights into what is causing the system to freeze, including errors and warnings that precede the freeze. This information is essential for diagnosing software or operating system issues that might be causing instability. Checking the temperature or updating drivers might be subsequent steps based on findings from the event logs.

Question 3
A technician receives a call from a user about a new USB 3.1 docking station. The user claims that their laptop does not charge when connected to the dock. The user confirms that the AC adapter for the dock is plugged in. Which of the following is the most likely cause?
Answer : A
If a laptop does not charge when connected to a USB 3.1 docking station despite the AC adapter being plugged in, the most likely reason is that the dock is not designed to provide power passthrough. This means that the dock's primary function is connectivity for peripherals rather than power delivery to the laptop. The other options are possible but less likely if the sole issue is the absence of charging functionality when the dock and its power supply are properly connected.

Question 4
A technician is upgrading a user's laptop from an HDD to an SSD. The user's laptop only has a single bay for a hard drive. Which of the following characteristics of the SSD is the most important in this scenario?
Answer : C
When upgrading a laptop's storage from an HDD to an SSD, especially in laptops with only a single bay for a hard drive, the most critical characteristic to consider is the form factor. The form factor must match the physical dimensions and interface of the original HDD to ensure that the SSD can fit into the bay and connect properly. Storage size (B) is important for capacity reasons, transfer speed (D) affects performance, and partition type (A) is a software configuration aspect, but the form factor (C) is crucial for the physical compatibility of the SSD with the laptop.

Question 5
Which of the following differentiates PAN from LAN?
Answer : A
A Personal Area Network (PAN) is designed to connect devices in close proximity, typically within a few meters, often using wireless technologies like Bluetooth. This allows for the interconnection of smart devices such as smartphones, tablets, and wearables within an individual's personal space. Unlike a Local Area Network (LAN), which covers a larger geographical area such as a home or office building and can support wired and wireless connections, a PAN specifically facilitates wireless connections between personal devices.

Question 6
A user reports that files are taking hours to transfer from a device to an external USB drive. The technician confirms that the device's cables are connected and the correct USB port is being used. Which of the following steps should the technician take next when troubleshooting the issue?
Answer : B
When a device is experiencing slow file transfers to an external USB drive and the physical connections are confirmed to be correct, the next step is to update the device drivers. Outdated or corrupt drivers can cause suboptimal performance and slow transfer speeds. Updating the drivers can resolve these issues and improve the device's communication with the USB drive, leading to faster file transfers.
A user reports that a laser printer's toner does not stick to the paper. The user has tried multiple brands of paper and is unable to print legible documents. Which of the following should be replaced to ensure proper printouts?
Answer : A
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.
