* VLAN Tag Translation :
* VLAN tag translation is used to modify VLAN tags in packets as they pass through the OLT.
* The tag-transform parameter determines how VLAN tags are handled during service flow creation.
* Behavior of tag-transform = default :
* When tag-transform is set to default, the OLT applies predefined rules for VLAN tag conversion based on the SVLAN (Service VLAN) attributes.
* These rules vary depending on the SVLAN type (e.g., Common, QinQ, Stacking), resulting in different behaviors.
* Why TRUE?
* The statement accurately reflects the behavior of the tag-transform parameter when set to default. Different SVLAN attributes lead to different tag conversion rules.
Thus, the correct answer is A .
