[All NS0-516 Questions]

Which iSCSI setting would you change from its default value to increase the throughput of an iSCSI host port on a NetApp E-Series system?

Amaximum transmission unit (MTU)

Bflow control

CChallenge-Handshake Authentication Protocol (CHAP)

DTime to Live (TTL)

Show Suggested Answer

Suggested Answer: A

To increase the throughput of an iSCSI host port on a NetApp E-Series system, you should change the maximum transmission unit (MTU) setting from its default value.

Maximum Transmission Unit (MTU): The MTU size determines the largest packet that can be sent over the network without needing to be fragmented. By increasing the MTU size, you can reduce the overhead associated with packet processing and improve throughput. For example, setting the MTU to 9000 bytes (Jumbo Frames) can enhance performance for iSCSI traffic.

I’m leaning towards MTU as well. I saw a similar question where adjusting MTU helped with performance, but I’m a bit confused about the other options.

I remember practicing a question about iSCSI settings, and I feel like flow control was mentioned as important for managing traffic, but I can't recall if it directly affects throughput.

I think it might be the maximum transmission unit (MTU) since larger packets can improve throughput, but I'm not entirely sure.
