Refer to the exhibit. A customer must ensure that the interface on a switch has enough resources to sustain the line rate traffic during peak load. Which action meets this requirement?

Changing the interface's rate mode to 'dedicated' ensures that the port receives its full, guaranteed bandwidth and associated hardware resources, preventing resource contention with other ports. This configuration allows the port to consistently sustain line rate traffic even under peak load conditions, which is crucial for performance-sensitive applications requiring predictable throughput.

Setting Transmit B2B (Buffer-to-Buffer) credit to 16 is a Fibre Channel flow control parameter to manage buffer utilization, not a direct mechanism to allocate overall port resources to sustain line rate traffic.

Changing the port mode to NL (Node Loop) configures the Fibre Channel port to connect to arbitrated loop devices, which is a specific connectivity type and does not address the general requirement of ensuring resources for line rate traffic on a switch interface.

Increasing the data field size to 9000 bytes refers to enabling jumbo frames for Ethernet, which optimizes efficiency for large data transfers but does not ensure the underlying dedicated bandwidth or processing resources for the interface to handle line rate traffic.
