The administrator wants to have central storage for all files to be stored for each VM. What is used to connect a host to a SAN utilizing a fiber connection?

1. VNIC

2. NIC

3. HBA

4. SCSI adapter

The correct answer is: HBA

The correct option is a Host Bus Adapter (HBA) because it is specifically designed to connect a host system to a Storage Area Network (SAN) using a fiber connection. HBAs serve as the interface between the server and the SAN, allowing data to be transmitted using fiber optic cables, which are favored for their speed and ability to transmit data over long distances without significant loss. In the context of virtualization, using an HBA enables VMs to access centralized storage efficiently, making it easier to manage and backup data. The HBA is vital for achieving high throughput and low latency, which are essential for performance in environments that require substantial data handling capabilities, such as cloud infrastructure. Understanding the function of other options provides context: a Virtual Network Interface Card (VNIC) is used for virtual network connections within a virtualization environment, but it does not manage storage connections. A Network Interface Card (NIC) handles standard networking connections over Ethernet but is not designed for direct connection to a SAN. SCSI adapters are primarily used for connecting SCSI devices over a bus interface; while they may be used for storage as well, they do not facilitate the high-performance connectivity that an HBA provides over fiber optics in SAN environments. Therefore, the most appropriate choice for
