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?

No switchport access vlan 20

Delete flash:vlan.dat

Delete vlan.dat

No vlan 20

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

A router with at least two LAN interfaces is needed

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

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 interface

To the SVI

To the VLAN

To the sub-interface

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

Native VLAN ID

Data VLAN ID

Unused VLAN ID

Management VLAN ID

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

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

What is a disadvantage of using RoaS (Router-on-a-Stick) inter-VLAN Routing?

Requires the use of more physical interfaces than legacy inter-VLAN routing

Does not support VLAN-tagged packets

Does not scale well beyond 50 VLANs

Requires the use of multiple router interfaces configured to operate as access links

10.

Which of the following statements is TRUE about trunk ports?

A trunk port supports a single VLAN

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 uses a straight-through Ethernet cable when connecting two switches
