What is the supported speed and frame size on the cluster interconnect?
The correct answer is D. 10 Gb / 9000 mtu. The NetApp cluster interconnect network requires 10 Gb Ethernet with jumbo frames (9000 MTU) to support high-throughput, low-latency inter-node communication.

Why each option
The NetApp cluster interconnect network requires 10 Gb Ethernet with jumbo frames (9000 MTU) to support high-throughput, low-latency inter-node communication.
1 Gb speed is insufficient for cluster interconnect, and 1500 MTU is standard Ethernet without jumbo frames - neither meets the requirement.
1 Gb is insufficient bandwidth for cluster interconnect traffic even though 9000 MTU is correct for jumbo frames.
10 Gb speed is correct, but 1500 MTU (standard frames) is not supported - jumbo frames at 9000 MTU are required.
NetApp specifies 10 GbE as the required speed for cluster interconnect ports, combined with a 9000-byte MTU (jumbo frames) to maximize efficiency for the high-volume internal traffic - such as data mirroring and storage failover - that flows between cluster nodes. Using jumbo frames reduces per-packet overhead, which is critical for cluster health and performance.
Specific speed and MTU requirements do exist and are mandated by NetApp for cluster interconnect ports; there is no flexibility on these values.
