The M.2 form factor (formerly known as the Next Generation Form Factor, or NGFF) is a more modern type of internally mounted expansion card that replaces the previous mSATA (Mini- SATA) standard. Unlike standard HDDs and SSDs, M.2 drives aren't connected to a motherboard via a cable, they're instead plugged directly into the motherboard using a dedicated M.2 connector slot.

Mobile Device Management (MDM) policies are crucial for companies that allow employees to use personal devices for work duties. MDM enables the company to enforce security policies, manage and secure corporate data on personal devices, and ensure compliance with company standards. It allows for remote management of these devices, including the ability to remotely wipe company data if the device is lost or stolen, without impacting personal data, thereby protecting company information effectively.

When configuring a router for a small business, the first setting a technician should configure is DHCP (Dynamic Host Configuration Protocol). DHCP is responsible for automatically assigning IP addresses to devices on the network, which is essential for enabling communication within the network. Without DHCP, devices would not receive the necessary IP configurations to communicate effectively.

Secure Boot is a feature of UEFI (Unified Extensible Firmware Interface) that prevents unauthorized software from running during the boot process. Secure Boot verifies the digital signature of the boot loader and the operating system, and only allows them to run if they are signed by a trusted authority. However, Secure Boot can also prevent some legitimate software, such as firmware updates, from running if they are not signed or recognized by the system.
Therefore, the technician may need to disable Secure Boot in order to install a firmware update for the system board UEFI from a USB key.

The issue is related to interference from the microwave, which operates at 2.4GHz, the same frequency as some Wi-Fi channels. To avoid this interference, the technician should configure the Wi- Fi access point (AP) to use a 5GHz band, which has more channels and less interference from other devices. Changing the Wi-Fi operation channel may not solve the problem if the microwave interferes with multiple channels. Increasing the power output of the AP may not overcome the interference and may cause more interference to other devices. Changing the SSID to hidden does not affect the interference at all, and may make it harder for users to connect to the network.
