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

Delete vlan.dat

No switchport access vlan 20

No vlan 20

Delete flash:vlan.dat

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 returned to VLAN 1

VLAN 30 will be deleted

An error message would be displayed

The FE Port will be shutdown

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

Data

Native

Default

Management

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

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

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

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 interface

To the sub-interface

To the SVI

To the VLAN

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

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

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

Which characteristic matches extended range VLANs?

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

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

CDP can be used to learn and store these VLANs

10.

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 router with at least two LAN interfaces is needed

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

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

A multilayer switch is needed
