| Question ID 16033 | In a switched environment, what does the IEEE 802.1Q standard describe?
|
| Option A | the operation of VTP
|
| Option B | a method of VLAN trunking
|
| Option C | an approach to wireless LAN communication
|
| Option D | the process for root bridge selection
|
| Option E | VLAN pruning
|
| Correct Answer | B |
Explanation Explanation: A broadcast domain must sometimes exist on more than one switch in the network. To accomplish this, one switch must send frames to another switch and indicate which VLAN a particular frame belongs to. On Cisco switches, a trunk link is created to accomplish this VLAN identification. ISL and IEEE 802.1Q are different methods of putting a VLAN identifier in a Layer 2 frame. The IEEE 802.1Q protocol interconnects VLANs between multiple switches, routers, and servers. With 802.1Q, a network administrator can define a VLAN topology to span multiple physical devices. Cisco switches support IEEE 802.1Q for FastEthernet and Gigabit Ethernet interfaces. An 802.1Q trunk link provides VLAN identification by adding a 4-byte tag to an Ethernet Frame as it leaves a trunk port.
| Question ID 16034 | Refer to the exhibit.
A network technician is asked to design a small network with redundancy. The exhibit
represents this design, with all hosts configured in the same VLAN. What conclusions can
be made about this design?
|
| Option A | This design will function as intended.
|
| Option B | Spanning-tree will need to be used.
|
| Option C | The router will not accept the addressing scheme.
|
| Option D | The connection between switches should be a trunk.
|
| Option E | The router interfaces must be encapsulated with the 802.1Q protocol.
|
| Correct Answer | C |
Explanation Explanation: Each interface on a router must be in a different network. If two interfaces are in the same network, the router will not accept it and show error when the administrator assigns it.
