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

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

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

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 interface

To the VLAN

To the sub-interface

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

Routing Information Protocol

Cisco Discovery Protocol

Spanning Tree Protocol

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

VLAN 30 will be deleted

The FE Port will be returned to VLAN 1

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

Native

Default

Management

Data

Which characteristic matches extended range VLANs?

CDP can be used to learn and store these VLANs

VLAN IDs exist between 1006 to 4094 & they are saved in the running-config file by default

VLANs are initialized from flash memory & they are commonly used in small networks

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 shutdown command in interface configuration mode to return it to the default configuration and then configure the port for VLAN 3

Enter the switchport access vlan 3 command in interface configuration mode

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

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

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

Delete vlan.dat

No vlan 20

Delete flash:vlan.dat

No switchport access vlan 20

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

10.

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?

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

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

A Router with at least two LAN interfaces should be used
