SG0-001 · Question #442

Which of the following is an advantage of an iSCSI SAN over a FC SAN?

The correct answer is D. Lower implementation costs. An iSCSI SAN's primary advantage over a Fibre Channel (FC) SAN is its significantly lower implementation costs.

Why each option

An iSCSI SAN's primary advantage over a Fibre Channel (FC) SAN is its significantly lower implementation costs.

AHigher performance

Fibre Channel SANs generally offer higher performance and lower latency due to their dedicated, lossless protocol and network infrastructure.

BHigher scalability

While both can scale, Fibre Channel often provides greater scalability for very large, high-performance enterprise environments.

CLower latency

Fibre Channel SANs typically exhibit lower latency because they operate over a dedicated network using a native storage protocol, avoiding the overhead of TCP/IP.

DLower implementation costsCorrect

iSCSI SANs utilize standard Ethernet networking components, such as NICs, switches, and cabling, which are generally less expensive and more readily available than the specialized Fibre Channel HBAs, switches, and fiber optic cabling required for FC SANs. This allows organizations to leverage existing IP infrastructure and expertise, reducing overall deployment and maintenance expenses.
