Explanation
Dropping a smartphone can damage the digitizer, which is the component responsible for sensing touch input.
This can cause issues with tapping and swiping on the screen, as well as other touchscreen-related issues.

Explanation
The most secure way to implement fingerprint readers would be to restrict device access to only the user to whom the laptop is assigned. This ensures that only authorized personnel have access to the device, reducing the risk of unauthorized access and data breaches.

Explanation
This is because a docking station can connect multiple monitors to a laptop without using USB ports, which are disabled in this scenario. A splitter cable would only allow two monitors to be connected, not three. A discrete graphics card would require opening the laptop and installing hardware, which may not be feasible or allowed in a high-security environment. An HDMI switch would only allow one monitor to be active at a time, not all three simultaneously.

Explanation
RAID 10 array is often used for server virtualization as it provides both redundancy and performance benefits.
It uses a combination of mirroring and striping to provide both fault tolerance and improved I/O performance.
An optical disk drive or eMMC storage device would not provide enough storage or performance for a VM host server, while a 15,000rpm drive may provide good performance but would not provide redundancy for fault tolerance. Therefore, a RAID 10 array is the best option for cost-effective storage that will be used for all VMs that run from the server.

Explanation
The 802.11n wireless networking standard supports Multiple Input Multiple Output (MIMO) technology.
MIMO technology uses multiple antennas on both the transmitting and receiving devices to improve wireless performance by increasing the amount of data that can be transmitted simultaneously. 802.11a, 802.11b, and
802.11g do not support MIMO technology. References: CompTIA A+ Certification Exam: Core 1 - Objective
