|
| (a) All frames of VLAN A and VLAN B will be tagged when traversing the hybrid link. 當傳輸於混合鏈路時,所有 VLAN A 和 VLAN B的訊框都會貼上標籤 | |
| (b) All frames of VLAN A, VLAN B and VLAN C will be tagged when traversing the hybrid link. 當傳輸於混合鏈路時,所有VLAN A、VLAN B和VLAN C的訊框都會貼上標籤 | |
| (c) All frames of VLAN C will be untagged when traversing the hybrid link. 當傳輸於混合鏈路時,所有 VLAN C 的訊框都不會貼上標籤 | |
| (d) All frames of VLAN B and VLAN C will be untagged when traversing the hybrid link. 當傳輸於混合鏈路時,所有 VLAN B 和VLAN C 的訊框都不會貼上標籤 | |
| (e) All frames of VLAN C will be tagged when traversing the hybrid link. 當傳輸於混合鏈路時,所有 VLAN C 的訊框都會貼上標籤 |

5.14. Which of the following statements about the relationship between VLAN and spanning tree are correct ? 下列哪些關於虛擬區域網路與擴張樹關聯性的敘述是正確的 ? |
| (a) The set of paths to connect the members of a VLAN is a subset of the spanning tree of the bridged LAN. 連接虛擬區域網路成員的路徑集合是此橋接網路上擴張樹的子集合 | |
| (b) The set of paths to connect the members a VLAN always is identical to the spanning tree of the bridged LAN. 連接虛擬區域網路成員的路徑集合與此橋接網路上擴張樹的路徑完全相同 | |
| (c) The set of paths to connect the members of a VLAN is fixed. 連接虛擬區域網路成員的路徑集合是固定不變的 | |
| (d) The set of paths to connect the members of a VLAN is dynamic. 連接虛擬區域網路成員的路徑集合是動態改變的 | |
| (e) The set of paths to connect the members of different VLANs may be different. 不同虛擬區域網路的成員路徑集合可能會不同 |
