The solution that is used for failover, providing access to all the services currently in use by an organization without having to physically move any servers or employees, is the cloud. The cloud is a term that refers to a network of remote servers that are hosted on the Internet and provide various services, such as storage, computing, networking, and applications. The cloud can be used for failover, which is a backup operation that automatically switches to a standby system or service in case of a failure or disruption of the primary system or service. By using the cloud for failover, an organization can ensure continuous availability and accessibility of its services without requiring any physical relocation or intervention.

CIFS (Common Internet File System) is a protocol that allows file sharing across different operating systems, such as Unix and Windows. It supports read and write access to files and folders on a network share. It is also known as SMB (Server Message Block). Verified References: [CIFS], [File sharing]

P2V (Physical to Virtual) is a method of converting a physical server into a virtual machine that can run on a hypervisor. This method can be used to replace 4U rack servers with VMs without losing any data, as it preserves the configuration and state of the original server. P2V can also reduce hardware costs, power consumption, and space requirements. Verified References: [What is P2V?]

Changing the boot order on the server and restricting console access would prevent unauthorized access attempts via USB devices at startup, as the server would not boot from any external media and only authorized users could access the console. Setting a BIOS/UEFI password on the server would also help, but it could be bypassed by resetting the CMOS battery or using a backdoor password. Configuring the host OS to deny login attempts via USB would not prevent booting from a malicious USB device that could compromise the system before the OS loads. Disabling all the USB ports on the server would limit functionality, as some peripherals or devices may need to use them. References:

A differential backup is a type of backup that copies all the files that have changed since the last full backup. A differential backup requires more storage space than an incremental backup, which only copies the files that have changed since the last backup of any type, but it also requires less time to restore in case of data loss. By combining a full, weekly backup with daily differential backups, the administrator can ensure that only two backup sets are needed to restore a full backup as quickly as possible.

This is the most secure method to access servers located in remote branch offices because MFA stands for multi-factor authentication, which requires users to provide more than one piece of evidence to prove their identity. An out-of-band solution means that one of the factors is delivered through a separate channel, such as a phone call, a text message, or an email. This adds an extra layer of security and prevents unauthorized access even if a password is compromised.References:https://docs.microsoft.com/en-us/azure/active-directory/authentication/concept-mfa-howitworks

Data-at-rest encryption is a method of encrypting data while it is stored on a storage device, such as a hard drive, an SSD, or a tape library. This ensures that if the data is stolen or lost, it will be unreadable without the encryption key. Data-at-rest encryption does not protect data while it is in transit over the network, in use by the CPU or memory, or attached to an email.
