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?

Delete flash:vlan.dat

No switchport access vlan 20

No vlan 20

Delete vlan.dat

What is the benefit of using VLANs?

A reduction in the number of trunk links

Improved IT staff efficiency

Security, Cost reduction

End user satisfaction

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

Which one of these is a characteristic of the 802.1Q protocol?

It modifies the 802.3 frame header and thus requires that the FCS be recomputed

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 is used exclusively for tagging vlan frames and does not address network re-convergence following switched network topology changes

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

Management

Default

Native

Data

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

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

Cisco Discovery Protocol

Spanning Tree Protocol

Routing Information Protocol

802.1q

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 at least two LAN interfaces should be used

A Router with one VLAN interface is needed to connect to the SVI on a switch

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
