What is a VLAN?

• A VLAN is a type of physical network switch.
• A VLAN is a Virtual Local Area Network that segments a network into distinct broadcast domains.
• A VLAN is a protocol for internet communication.
• A VLAN is a wireless network standard.

Multiple Choice

VLANS can segment a network; what does segmentation mean?

• Segmentation is the process of encrypting network data.

Multiple Choice

VLANS are flexible because

• VLANS require physical changes to the network infrastructure.
• VLANS are flexible because they enable network segmentation and can be easily configured.
• VLANS are only used for wireless networks.
• VLANS are inflexible and cannot be configured easily.

Multiple Choice

Each VLAN is assigned a

• VLAN Name
• VLAN Type
• VLAN Protocol
• VLAN ID

Multiple Choice

Each device is a ______ of a VLAN.

• member
• group
• segment
• component

Multiple Choice

Packets are _____with the VLAN ID to route only through that VLAN.

• untagged
• tagged
• broadcasted
• isolated

Multiple Choice

In order for one VLAN to communicate with another, WHAT needs to be enabled?

• Broadcasting must be enabled for all devices.
• Switching must be configured on all ports.
• VLAN tagging must be disabled.
• Inter-VLAN routing must be enabled.

Multiple Choice

This is a method of marking data packets with a VLAN ID.

• Network segmentation
• Port tagging

• Packet filtering
• VLAN identification

Multiple Choice

These types of ports are configured to receive and understand packets that have a VLAN ID.

• access ports
• management ports
• hybrid ports
• tagged ports

Multiple Choice

These type of ports are set to receive data without a VLAN ID.

• Untagged ports

• Trunk ports
• Router ports
• Hybrid ports

Multiple Choice

Another name for TAGGED ports is

• access ports
• hybrid ports
• static ports
• trunk ports

Multiple Choice

Another name for UNTAGGED ports are

• routing ports
• access ports
• hybrid ports
• trunk ports

Multiple Choice

The default VLAN ID is usually

• 100
• 1
• 2
• 10

Multiple Choice

VLAN ID 1 should or should not be used?

• can be used in some cases
• should not be used
• should be used
• is recommended for default settings

Multiple Choice

What could happen if the Native VLAN is VLAN1?

• Improved VLAN segmentation and isolation.
• Security vulnerabilities and potential data leaks.
• Enhanced compatibility with all devices.
• Increased network speed and performance.

Multiple Choice

Why are voice VLANs important?

• Voice VLANs are important because they ensure high-quality voice communication by prioritizing voice traffic and separating it from data traffic.
• Voice VLANs reduce the need for network security measures.
• Voice VLANs are only necessary for video traffic.
• Voice VLANs are used to increase data transfer speeds.

Multiple Choice

A VLAN connected to critical systems and is isolated from user data traffic is known as

• Community VLAN
• Public VLAN
• Management VLAN
• Private VLAN

Multiple Choice

When multiple switches need to move VLAN packets from one switch to another, what needs to be enabled for it work?

• Disable VLAN Trunking Protocol (VTP) and configure access ports.
• Use static routing between switches instead of VLANs.
• Enable Spanning Tree Protocol (STP) without configuring trunk ports.
• Enable VLAN Trunking Protocol (VTP) and configure trunk ports.

Multiple Choice

VIDs are defined by what IEEE standard?

• IEEE 802.15
• IEEE 802.3
• IEEE 802.11
• IEEE 802.1Q

Multiple Choice

Since VLANS and switches work at layer 2, data that needs to be routed usually works at layer 3. Because of this VLAN IDs need to be on THIS DEVICE for it to work.

• Firewall
• Router or Layer 3 switch
• Layer 1 switch
• Hub

Multiple Choice

Which is the LIE?

• Each device in a VLAN is assigned a unique VLAN ID. 

• Untagged ports are set to receive data without a VLAN identifier.

• A Native VLAN receives all untagged frames.
