QSFP+ is a type of connector that should be used to connect a server to a switch that uses 40G network connectivity. QSFP+ (Quad Small Form-factor Pluggable Plus) is a compact, hot-pluggable transceiver module that supports data rates up to 40 Gbps. QSFP+ modules can be used for various network protocols and media types, such as Ethernet, Fibre Channel, InfiniBand, or optical fiber. QSFP+ modules have a 38-pin edge connector and can be inserted into a QSFP+ port on a switch or a server. SFP+ (Small Form-factor Pluggable Plus) is a type of connector that supports data rates up to 10 Gbps, but not 40 Gbps. SFP+ modules have a 20-pin edge connector and can be inserted into an SFP+ port on a switch or a server. GBIC (Gigabit Interface Converter) is an older type of connector that supports data rates up to 1 Gbps, but not 40 Gbps. GBIC modules have an SC duplex connector and can be inserted into a GBIC port on a switch or a server. SFP (Small Form-factor Pluggable) is another older type of connector that supports data rates up to 1 Gbps or 4 Gbps, but not 40 Gbps. SFP modules have an LC duplex connector and can be inserted into an SFP port on a switch or a server. References:

Out-of-band console is a tool that can be used to command a remote shutdown of a physical Linux server. Out-of-band console is a method of accessing a server’s console through a dedicated management port or device that does not rely on the server’s operating system or network connection. Out-of-band console can be used to power cycle, reboot, update firmware, monitor performance, and perform other tasks remotely even if the server is unresponsive or offline. Crash cart is a mobile unit that contains a keyboard, monitor, mouse, and other tools that can be used to troubleshoot a server on-site, but it requires physical access to the server. IP KVM (Internet Protocol Keyboard Video Mouse) switch is a hardware device that allows remote access to multiple servers using a web browser or a client software, but it requires network connectivity and may not work if the SSH connection is lost. RDP (Remote Desktop Protocol) is a protocol that allows remote access to a Windows server’s graphical user interface, but it does not work on Linux servers and requires network connectivity.

The best backup methods to use to support the management’s priorities are differential and incremental. A backup is a process of copying data from a source to a destination for the purpose of restoring it in case of data loss or corruption. There are different types of backup methods that vary in terms of speed, efficiency, and storage requirements. Differential and incremental backups are two types of partial backups that only copy the data that has changed since the last full backup. A full backup is a type of backup that copies all the data from the source to the destination. A full backup provides the most complete and reliable restore option, but it also takes the longest time and requires the most storage space. A differential backup copies only the data that has changed since the last full backup. A differential backup provides a faster restore option than an incremental backup, but it also takes more time and requires more storage space than an incremental backup. An incremental backup copies only the data that has changed since the last backup, whether it was a full or an incremental backup. An incremental backup provides the fastest and most efficient backup option, but it also requires multiple backups to restore the data completely.

A core installation is a type of installation method that is best suited to meet the company policy that states no one is to log in directly to the server. A core installation is a minimal installation option that is available when deploying some editions of Windows Server. A core installation includes most but not all server roles and features, but does not include a graphical user interface (GUI). A core installation can only be managed remotely using command-line tools such as PowerShell or Windows Admin Center, or using graphical tools such as Server Manager or Remote Desktop from another computer. This reduces the attack surface, resource consumption, and maintenance requirements of the server. A GUI installation is a type of installation method that includes a graphical user interface (GUI) and allows local or remote management using graphical tools or command-line tools. A virtualized installation is a type of installation method that involves creating and running one or more virtual machines on a physical host using a hypervisor such as Hyper-V or VMware. A clone installation is a type of installation method that involves creating an exact copy of an existing server’s configuration and data on another server using tools such as Sysprep or Clonezilla.
