The correct answers are A and C.

OBJ-3.8: According to CompTIA, the five main things you need to include for network-attached storage (NAS) devices are (1) media streaming capabilities, (2) file-sharing capabilities, (3) Gigabit NIC, (4) RAID array, and (5) hard drives. Based on the options provided, you should pick the RAID 5 and Gigabit NIC for this device’s configuration. The RAID 5 will provide both speed and redundancy to the NAS device, whereas the RAID 0 would provide only speed without redundancy. The Gigabit NIC will provide 1 Gbps (1000 Mbps) of network speed instead of the 100 Mbps provided by a FastEthernet NIC. For a NAS device, you should use multiple hard disk drives in a RAID, not a single 1 TB HDD or 1 TB SSD. For a NAS, it is preferred to choose hard drives over solid-state drives because of the increased storage capacity and lower cost.
