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

An FE Port on a Cisco Switch is assigned to VLAN 30. If the command no switchport access vlan 30 is entered on this FE interface, what will happen?

The FE Port will be shutdown

An error message would be displayed

The FE Port will be returned to VLAN 1

VLAN 30 will be deleted

A network administrator is determining the best placement of VLAN trunk links. Which two types of point-to-point connections utilize VLAN trunking?

Between a switch and a client PC

Between a switch and a server that has an 802.1Q NIC

Between two switches that utilize multiple VLANs which do not have any common vlan

Between a switch and a network printer

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 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

Enter the switchport access vlan 3 command in interface configuration mode

Which type of VLAN is used to designate which traffic is untagged when crossing a trunk port?

Native

Management

Default

Data

Which command is used to remove only VLAN 20 from a Cisco Switch?

No vlan 20

Delete vlan.dat

No switchport access vlan 20

Delete flash:vlan.dat

Which one of these is a characteristic of the 802.1Q protocol?

It is a layer 2 messaging protocol which maintains vlan configurations across network

It includes an 8-bit field which specifies the priority of a frame

It modifies the 802.3 frame header and thus requires that the FCS be recomputed

It is used exclusively for tagging vlan frames and does not address network re-convergence following switched network topology changes

Which of the following statements is TRUE about trunk ports?

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

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

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

Data VLAN ID

Unused VLAN ID

Management VLAN ID

Native VLAN ID

10.

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

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

Does not support VLAN-tagged packets

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

Does not scale well beyond 50 VLANs
