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

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

A multilayer switch is needed

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

What is the benefit of using VLANs?

Security, Cost reduction

End user satisfaction

A reduction in the number of trunk links

Improved IT staff efficiency

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

Data VLAN ID

Unused VLAN ID

Native VLAN ID

Management VLAN ID

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 two switches that utilize multiple VLANs which do not have any common vlan

Between a switch and a server that has an 802.1Q NIC

Between a switch and a network printer

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

Does not scale well beyond 50 VLANs

Does not support VLAN-tagged packets

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

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

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 sub-interface

To the VLAN

To the SVI

To the interface

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?

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

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

10.

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 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

Enter the no shutdown command in interface configuration mode to return it to the default configuration and then configure the port for VLAN 3
