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 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 network printer

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

Between a switch and a client PC

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

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 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

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

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 SVI

To the VLAN

To the interface

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

What is the benefit of using VLANs?

Improved IT staff efficiency

End user satisfaction

Security, Cost reduction

A reduction in the number of trunk links

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

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

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

A multilayer switch is needed

Which type of VLAN is used to designate which traffic is untagged when crossing a trunk port?

Data

Management

Native

Default

What is a characteristic of legacy inter-VLAN routing

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

Only one VLAN can be used in the topology

10.

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

The port goes back to the default VLAN

The port becomes inactive

The port automatically associates itself with the native VLAN

The port creates the VLAN again
