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

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

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

A Router with at least two LAN interfaces should be used

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

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

A high school uses VLAN15 for the laboratory network and VLAN30 for the faculty network. What is required to enable communication between these two VLANs while using the RoaS (Router-on-a-Stick) approach?

A switch with a port that is configured as a trunk is needed when connecting to the router

A multilayer switch is needed

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

A router with at least two LAN interfaces is needed

Which characteristic matches extended range 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

CDP can be used to learn and store these VLANs

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

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

Native

Default

Management

Data

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

Delete flash:vlan.dat

No switchport access vlan 20

No vlan 20

Delete vlan.dat

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

Routing Information Protocol

802.1q

Spanning Tree Protocol

Cisco Discovery Protocol

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
