Explanation
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. Common VLAN is the simplest and most suitable choice for scenarios requiring single-tag VLAN Thus, the correct answer is A.
