New Release SK0-005 CompTIA Server+ Questions

JBOD (Just a Bunch Of Disks) is a storage configuration that combines different types and sizes of hard drives into one logical unit without any RAID level or redundancy. It allows users to see all the drives within the unit as one large storage space. JBOD can utilize all the available capacity of the drives but does not provide any performance or fault tolerance benefits. Verified References: [JBOD], [RAID]

A SD card is a type of flash memory card that can be used to store data and run applications. A SD card can be used to install a Type 1 hypervisor on a server, as it provides fast boot time, low power consumption, and high reliability. A Type 1 hypervisor runs directly on the underlying computer’s physical hardware, interacting directly with its CPU, memory, and physical storage. For this reason, Type 1 hypervisors are also referred to as bare-metal hypervisors. A Type 1 hypervisor takes the place of a host operating system and VM resources are scheduled directly to the hardware by the hypervisor123. A NAS drive (B) is a type of network-attached storage (NAS) device that provides shared access to files and data over a network. A NAS drive cannot be used to install a Type 1 hypervisor on a server, as it requires a network connection and a host operating system to function. A SATA drive © is a type of hard disk drive (HDD) or solid state drive (SSD) that uses the Serial ATA (SATA) interface to connect to a computer. A SATA drive can be used to install a Type 1 hypervisor on a server, but it may have some disadvantages compared to a SD card, such as slower boot time, higher power consumption, and lower reliability. A SAS drive (D) is a type of hard disk drive (HDD) or solid state drive (SSD) that uses the Serial Attached SCSI (SAS) interface to connect to a computer. A SAS drive can also be used to install a Type 1 hypervisor on a server, but it may have similar disadvantages as a SATA drive, and it may also be more expensive and less compatible than a SD card.

Components of a Data Loss Solution

The power supply and the hard drive are two components that can most likely be swapped out while the server is still running, if they support hot swapping or hot plugging. Hot swapping or hot plugging means that the device can be added or removed without shutting down the system. The operating system automatically recognizes the changes that have been made. This feature is useful for minimizing downtime and improving availability. The CPU, the GPU, the cache, and the RAM are not hot swappable and require the system to be powered off before replacing them. References:
