Question 190
An HPE Aruba Networking engineer faces this wired-network scenario: Two switches must exchange VLAN 20 and VLAN 30 but a user in VLAN 30 cannot cross the uplink. Which implementation action BEST addresses the requirement?
Explanation
Correct Answer
A trunk forwards only VLANs permitted by its effective membership. The targeted implementation is to configure the trunk's allowed VLANs and native VLAN deliberately on both ends. The deployment succeeds when a tagged VLAN 30 test passes across the inter-switch uplink.
Incorrect Answers
This implementation choice fits a different situation: A department wants multiple 6300 access switches to behave as one manageable stack. It does not resolve the stated failure mode. For this case, the decisive implementation choice is to configure the trunk's allowed VLANs and native VLAN deliberately on both ends.
This implementation choice fits a different situation: A link aggregation group contains two ports but only one member forwards traffic. It does not resolve the stated failure mode. For this case, the decisive implementation choice is to configure the trunk's allowed VLANs and native VLAN deliberately on both ends.
This implementation choice fits a different situation: Two aggregation switches use VSX, but a downstream dual-homed LAG drops on peer failure. It does not resolve the stated failure mode. For this case, the decisive implementation choice is to configure the trunk's allowed VLANs and native VLAN deliberately on both ends.
