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

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

Native VLAN ID

Unused VLAN ID

Management VLAN ID

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

Management

Default

Native

Data

What is the benefit of using VLANs?

End user satisfaction

Security, Cost reduction

A reduction in the number of trunk links

Improved IT staff efficiency

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 network printer

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 client PC

What is a characteristic of legacy inter-VLAN routing

Only one VLAN can be used in the topology

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

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

The Router requires one Ethernet link for each VLAN

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

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 VLAN

To the SVI

To the sub-interface

To the interface

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

Delete vlan.dat

No switchport access vlan 20

Delete flash:vlan.dat

No vlan 20

10.

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

Does not scale well beyond 50 VLANs

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

Does not support VLAN-tagged packets
