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 characteristic matches extended range VLANs?

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

VLAN IDs exist between 1006 to 4094 & they are saved in the running-config file by default

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

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

Does not support VLAN-tagged packets

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

Does not scale well beyond 50 VLANs

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

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 creates the VLAN again

The port becomes inactive

The port automatically associates itself with the native 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 SVI

To the sub-interface

To the interface

To the VLAN

Which protocol is used in redundant network topologies to avoid receiving multiple copies of the same frame?

Routing Information Protocol

Spanning Tree Protocol

Cisco Discovery Protocol

802.1q

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

Management

Data

Native

Default

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

Native VLAN ID

Unused VLAN ID

Management VLAN ID

10.

A network administrator is determining the best placement of VLAN trunk links. Which two types of point-to-point connections utilize VLAN trunking?

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

Between a switch and a network printer

Between a switch and a client PC

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