What type of VLAN is used to carry VoIP

• Native

• Voice

• Data

• Default

Answer explanation

The correct VLAN type used to carry VoIP is 'Voice'. This VLAN is specifically designated for VoIP traffic.

What is the purpose of a VLAN?

• Segmenting a network

• Encrypting data

• Increasing internet speed

• Blocking websites

Answer explanation

The purpose of a VLAN is to segment a network, separating traffic into different virtual networks for improved security and efficiency.

What is the main advantage of using VLANs in a large network?

• Reduced network congestion

• Increased hardware cost

• Slower data transmission

• More network complexity

Answer explanation

The main advantage of using VLANs in a large network is reduced network congestion, as it helps segregate traffic and improve overall network performance.

Which protocol is commonly used for VLAN trunking?

• FTP

• SSH

• 802.1Q

• SMTP

Answer explanation

802.1Q is commonly used for VLAN trunking, allowing multiple VLANs to be carried over a single trunk line.

Which of the following commands can be used to verify inter-vlan routing? (Choose 2)

• show vlan

• ping

• show ip interface brief

• Show route

• tracert

Answer explanation

The commands 'ping' and 'tracert' can be used to verify inter-vlan routing by testing connectivity and tracing the route between VLANs.

What is the maximum number of VLANs supported by IEEE 802.1Q?

• 1000

• 4096

• 500

• 2000

Answer explanation

IEEE 802.1Q supports a maximum of 4096 VLANs, making the correct answer choice 4096.

What is a VLAN Trunk used for?

• WAN Link between two networks devices that carries ONLY one VLAN

• WAN Link between two networks devices that carries more than one VLAN

• point-to-point link between two network devices that carries more than one VLAN

• point-to-point link between two network devices that carries ONLY one VLAN

Answer explanation

A VLAN Trunk is a point-to-point link between two network devices that carries more than one VLAN, allowing multiple VLANs to pass through the connection.

What is inter-VLAN routing?

• Inter-VLAN routing allows communication between devices in different VLANs within the same network.

• Inter-VLAN routing is a security feature that blocks communication between VLANs.

• Inter-VLAN routing is a physical device that connects VLANs.

• Inter-VLAN routing is used for communication within the same VLAN only.

Answer explanation

Inter-VLAN routing allows communication between devices in different VLANs within the same network.

What is the purpose of VLAN tagging?

• Identifying different VLANs

• Increasing firewall security

• Enhancing wireless connectivity

• Improving server performance

Answer explanation

The purpose of VLAN tagging is to identify different VLANs, allowing for network segmentation and management.

What is added to a frame when traversing through a trunk link?

• OSI Framework

• IP Address

• MAC Address

• VLAN Tags

Answer explanation

When traversing through a trunk link, VLAN Tags are added to a frame to identify the VLAN the frame belongs to.
