A network administrator is configuring an IEEE 802.1Q trunk link between two managed switches to carry traffic for multiple VLANs over a single physical cable. Which of the following statements correctly describe the default operation and frame structure of IEEE 802.1Q trunking? (Select TWO.)
- Frames associated with standard tagged VLANs have a 4-byte header containing the VLAN ID inserted into the Ethernet frame.Cevap
- Frames belonging to the native VLAN are transmitted across the trunk link without an 802.1Q header tag.Cevap
- CTrunking enables hosts on different VLANs to communicate with each other directly at Layer 2 without requiring a router.
- DUntagged frames received on an 802.1Q trunk interface are automatically assigned to VLAN ID 4095.
Cevap
IEEE 802.1Q trunking inserts a 4-byte tag into frames for tagged VLANs and transmits native VLAN frames without an added VLAN header tag.
IEEE 802.1Q trunking operates by inserting a 4-byte header tag into standard Ethernet frames to identify VLAN membership across switches. Traffic belonging to the native VLAN is transmitted untagged by default.
