Explanation
Default Behavior of ONUs: By default, ONUs (Optical Network Units) connected to the same PON port of a Huawei OLT are isolated at Layer 2. This isolation ensures that ONUs cannot communicate directly with each other, even if they belong to the same service VLAN. The statement incorrectly claims that ONUs can communicate with each other at Layer 2 by default. In reality, Layer 2 isolation is a security feature designed to prevent unauthorized communication between ONUs. Enabling Communication: If Layer 2 communication between ONUs is required, it must be explicitly enabled through configuration (e.g., by disabling Layer 2 isolation). Thus, the correct answer is B.
