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

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?

VLAN 30 will be deleted

The FE Port will be shutdown

An error message would be displayed

The FE Port will be returned to VLAN 1

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

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 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

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 no vlan 2 and vlan 3 commands in global configuration mode

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

Enter the switchport access vlan 3 command in interface configuration mode

What is a characteristic of legacy inter-VLAN routing

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

Only one VLAN can be used in the topology

The Router requires one Ethernet link for each VLAN

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

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

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

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

When a Cisco switch receives untagged frames on a 802.1Q trunk port, which VLAN ID is the traffic switched to by default?

Management VLAN ID

Data VLAN ID

Native VLAN ID

Unused VLAN ID

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

10.

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

No switchport access vlan 20

No vlan 20
