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

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

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

Does not support VLAN-tagged packets

A small college uses VLAN 10 for the classroom network and VLAN 20 for the office network. What is needed to enable communication between these two VLANs while using legacy inter-VLAN routing?

A Router with at least two LAN interfaces should be used

A Switch with a port that is configured as trunk is needed to connect to a router

Two groups of switches are needed, each with ports that are configured for one VLAN

A Router with one VLAN interface is needed to connect to the SVI on a switch

Which of the following statements is TRUE about trunk ports?

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

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

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

A trunk port supports a single VLAN

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

Management

Default

Data

Native

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 no vlan 2 and vlan 3 commands in global configuration mode

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

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

802.1q

Routing Information Protocol

Cisco Discovery Protocol

Spanning Tree Protocol

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

Unused VLAN ID

Native VLAN ID

Data VLAN ID

Management VLAN ID

What is the benefit of using VLANs?

Security, Cost reduction

End user satisfaction

Improved IT staff efficiency

A reduction in the number of trunk links

10.

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 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

Between a switch and a client PC
