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

Does not scale well beyond 50 VLANs

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

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

Does not support VLAN-tagged packets

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

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

Delete vlan.dat

Delete flash:vlan.dat

No switchport access vlan 20

No vlan 20

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

What is a characteristic of legacy inter-VLAN routing

Only one VLAN can be used in the topology

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

The Router requires one Ethernet link for each VLAN

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

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 goes back to the default VLAN

The port automatically associates itself with the native VLAN

The port becomes inactive

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 multilayer switch is needed

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

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

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

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

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
