What does this interface command accomplish？（）A、 Causes the interface to apply ISL framing for traffic on VLAN 7B、 Configures the trunking interface to forward traffic from VLAN 7C、 Configures the interface to be a trunking port and causes traffic on VLAN 7 to be 802.1q taggedD、 Configures the trunking interface to send traffic from VLAN 7 untaggedE、 None of the other alternatives apply
What is the effect of applying the switchport trunk encapsulation dot1q command to a port on a Cisco Catalyst switch？（）A、By default， native VLAN packets going out this port will be tagged.B、Without an encapsulation command， 802.1Q will be the default encapsulation if DTP fails to negotiate a trunking protocol.C、The interface will support the reception of tagged and untagged traffic.D、If the device connected to this port is not 802.1Q-enabled， it will not be able to handle 802.1Q packets.
You have configured a Cisco Catalyst switch to perform Layer 3 routing via an SVI and have assigned that interface to VLAN 20. To check the status of the SVI， you issue the show interfaces vlan 20 command at the CLI prompt. You see from the output display that the interface is in an "up/up" state. What must be true in an SVI configuration to bring the VLAN and line protocol up？（）A、The port must be physically connected to another Layer 3 device.B、At least one port in VLAN 20 must be active.C、The Layer 3 routing protocol must be operational and receiving routing updates from neighboring peer devices.D、Because this is a virtual interface， the operational status will always be in an "up/up" state.
