To configure the VLAN trunking protocol to communicate VLAN information between two switches, what two requirements must be met? (Choose two)
- Each end of the trunk line must be set to IEEE 802.1E encapsulation.
- The VTP management domain name of both switches must be set the same.
- All ports on both the switches must be set as access ports.
- One of the two switches must be configured as a VTP server.
- A rollover cable is required to connect the two switches together.
- A router must be used to forward VTP traffic between VLANs.
Explanation: In Cisco switches there are two encapsulations: 802.1q and ISL so we can set two ends to ISL instead -> A is not correct.
The ports between two switches must be set to trunk ports so that they can exchange VLAN information through VTP -> C is not correct.
To connect two switches we can use cross-over cable or straight-through cable (because modern Cisco switches can “auto-sense”) but not rollover cable -> E is not correct.
To forward traffic in the same VLAN (between two or more switches) we can use switches only. If we want to forward VTP traffic between different VLANs we can use either a router or a Layer 3 switch -> F is not correct.
Two switches can only communicate when they are set to the same VTP domain name (and the same VTP password) -> B is correct.
One of the two switches must be set to VTP Server so that it can create VTP updates and advertise its VLAN information.
