Which connection type should a technician use to connect a server to a NAS?

To connect a server to a Network Attached Storage (NAS) device, Ethernet is the most commonly used connection type. This is because NAS systems typically operate over standard networking protocols, making Ethernet an efficient choice for both speed and ease of integration into existing network infrastructures. Ethernet allows for a straightforward and scalable connection, utilizing existing Ethernet networks without the need for special hardware configurations or complex setups.

In addition, Ethernet supports a range of bandwidth options—from Fast Ethernet (100 Mbps) to Gigabit Ethernet (1 Gbps) and even higher speeds—which can accommodate the data transfer needs of various applications. This flexibility is particularly beneficial when scaling storage solutions as network demands increase.

Although other options like HBA (Host Bus Adapter) and Fiber Fabric could be valid for connecting to different types of storage solutions, they are primarily used in more complex or high-performance environments, such as SAN (Storage Area Network) setups. A multiplexer typically serves a different function in networking and is not directly used for connecting servers to NAS devices. Thus, Ethernet stands out as the practical and widely adopted solution for this particular scenario.
