Huawei H35-210_V2.5 Exam - Topic 4 Question 92 Discussion
Topic #: 4
A school uses the POL networking and has only one campus. During VLAN design, VLANs are divided by service type and services are identified by a single VLAN tag. In this case, which VLAN attribute should be used?
VLAN Attributes :
Common VLAN : Used for standard VLAN tagging, where a single VLAN tag identifies the VLAN.
QinQ VLAN : Adds an additional VLAN tag for double-tagging, typically used in carrier networks.
Sub VLAN : Part of a Super VLAN configuration, used for IP address conservation.
Stacking VLAN : Similar to QinQ, used for double-tagging.
Scenario Analysis :
The school uses a single VLAN tag to identify services by type (e.g., student, faculty, administration).
Since only one VLAN tag is used, the appropriate VLAN attribute is Common .
Why A?
Common VLAN is the simplest and most suitable choice for scenarios requiring single-tag VLAN identification.
Thus, the correct answer is A .
