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 characteristic of legacy inter-VLAN routing

The Router requires one Ethernet link for each VLAN

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

Only one VLAN can be used in the topology

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

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

No vlan 20

Delete vlan.dat

Delete flash:vlan.dat

No switchport access vlan 20

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 includes an 8-bit field which specifies the priority of a frame

It is a layer 2 messaging protocol which maintains vlan configurations across network

It modifies the 802.3 frame header and thus requires that the FCS be recomputed

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

The FE Port will be returned to VLAN 1

An error message would be displayed

VLAN 30 will be deleted

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?

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

A multilayer switch is needed

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

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

Management VLAN ID

Data VLAN ID

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

Which of the following statements is TRUE about trunk ports?

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

A trunk port supports a single VLAN

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

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

10.

What happens to a port that is associated with VLAN 10 when the administrator deletes VLAN 10 from Cisco Switch?

The port creates the VLAN again

The port automatically associates itself with the native VLAN

The port goes back to the default VLAN

The port becomes inactive
