802.1Q Protocol Quiz (Online) - Networkwalks Academy

IEEE 802.1Q (sometimes referred to as 1Q or DOT1Q) is an industry standard based implementation of carrying traffic for multiple VLANs on a single trunking interface between two Ethernet switches like Cisco or Huawei switches

Which protocol is used in redundant network topologies to avoid receiving multiple copies of the same frame?

Routing Information Protocol

Spanning Tree Protocol

802.1q

Cisco Discovery Protocol

What is a characteristic of legacy inter-VLAN routing

The user VLAN must be the same ID number as the management VLAN

The Router requires one Ethernet link for each VLAN

Only one VLAN can be used in the topology

Inter-VLAN routing must be performed on a switch instead of a router

When configuring a Router as part of a RoaS (Router-on-a-Stick) inter-VLAN Routing topology, where should the IP address be assigned?

To the SVI

To the VLAN

To the sub-interface

To the interface

What is a disadvantage of using RoaS (Router-on-a-Stick) inter-VLAN Routing?

Does not support VLAN-tagged packets

Requires the use of multiple router interfaces configured to operate as access links

Requires the use of more physical interfaces than legacy inter-VLAN routing

Does not scale well beyond 50 VLANs

What happens to a port that is associated with VLAN 10 when the administrator deletes VLAN 10 from Cisco Switch?

The port becomes inactive

The port creates the VLAN again

The port automatically associates itself with the native VLAN

The port goes back to the default VLAN

Which of the following statements is TRUE about trunk ports?

A trunk port uses 802.1q to identify traffic from different VLANs

A trunk port uses a straight-through Ethernet cable when connecting two switches

A trunk port supports a single VLAN

A trunk port connects an end-user workstation to a switch

When a Cisco switch receives untagged frames on a 802.1Q trunk port, which VLAN ID is the traffic switched to by default?

Native VLAN ID

Data VLAN ID

Management VLAN ID

Unused VLAN ID

10.

On a Cisco Switch, what must the network administrator do to remove a Fast Ethernet port from VLAN 2 and assign it to VLAN 3?

Enter the switchport access vlan 3 command in interface configuration mode

Enter the switchport trunk native vlan 3 command in interface configuration mode

Enter the no shutdown command in interface configuration mode to return it to the default configuration and then configure the port for VLAN 3

Enter the no vlan 2 and vlan 3 commands in global configuration mode
