Which of the following does not belong to the VLAN type supported by MA5600T/MA5680T?

Question

Options

• AStardard VLAN
• BSmart VLAN
• CSub VLAN
• DMUX VLAN

• A
  4% (2)
• B
  18% (9)
• C
  71% (36)
• D
  8% (4)

Explanation

Sub VLAN is not a VLAN type supported by the MA5600T/MA5680T; these Huawei access devices specifically support three VLAN types: Standard VLAN, Smart VLAN, and MUX VLAN. Standard VLAN (A) is the basic 802.1Q VLAN used for simple traffic separation, and it is fully supported. Smart VLAN (B) is a Huawei-specific type designed to efficiently handle multicast or broadcast services across many users with a single VLAN, and it is also supported. MUX VLAN (D) is used to control whether users within the same VLAN can communicate with each other, and it too is a recognized type on these platforms. Sub VLAN belongs to the VLAN aggregation model found on Huawei routers and switches, where multiple sub VLANs share a single IP gateway via a super VLAN - it is a different concept entirely and not part of the MA5600T/MA5680T VLAN classification.

Memory tip: Remember the three supported types as "SSM" - Standard, Smart, MUX. If a fourth option does not fit that trio, it does not belong.
