Which of the following is the maximum transmission speed for iSCSI?
The correct answer is C. Equal to the speed of the link. iSCSI's transmission speed is not fixed at a specific rate but rather depends on the underlying network infrastructure it utilizes. It can operate at the maximum speed supported by the Ethernet link it's configured on.

Why each option
iSCSI's transmission speed is not fixed at a specific rate but rather depends on the underlying network infrastructure it utilizes. It can operate at the maximum speed supported by the Ethernet link it's configured on.
1Gbps is a common speed for older or less demanding iSCSI implementations but is not the maximum possible speed.
2Gbps Full-Duplex is not a standard Ethernet speed for iSCSI and does not represent its maximum capability.
iSCSI leverages standard Ethernet networks for data transmission, meaning its maximum speed is directly tied to the capabilities of the network interface cards (NICs), switches, and cabling in use. If the underlying network supports 10Gbps, 25Gbps, or even 100Gbps Ethernet, iSCSI can operate at those speeds, effectively matching the link's maximum throughput.
100Mbps is a very slow legacy Ethernet speed and significantly below what modern iSCSI implementations are capable of.
