Switching Ch 3 -4

VLAN tagging using the 802.1Q protocol is used to achieve the separation between different VLANs as they cross a trunk link. This protocol adds a tag to the Ethernet frame, which includes information about the VLAN ID. This allows switches to distinguish between different VLANs and properly route the traffic to the correct VLANs. By using VLAN tagging, multiple VLANs can be transmitted over a single trunk link, ensuring the separation and isolation of traffic between VLANs.

Since each VLAN contains 12 users, and there are 4 VLANs (Marketing, Sales, Production, and Admin), we need to have 4 different subnetworks to address each VLAN separately. Therefore, the correct answer is 4.

When Host C sends out an ARP request, it broadcasts the request to all hosts on the network. Host B, being on the same network as Host C, will receive the ARP request. Therefore, only Host B will see the message.

Switch SW 1 tags the frame with VLAN ID 10 and floods the frame to all hosts on switch SW 2 that are members of VLAN 10. This is because the hosts on both switches are configured with the VLAN membership shown. By tagging the frame with VLAN ID 10, switch SW 1 ensures that the frame is only forwarded to hosts on switch SW 2 that are part of VLAN 10, preventing unnecessary flooding to hosts on other VLANs.

The correct answer is that VLAN 1 has all ports as members by default and is also the default management VLAN. This means that all ports on the switch are automatically assigned to VLAN 1 unless they are manually assigned to a different VLAN. VLAN 1 is also used as the default VLAN for managing the switch, allowing for remote access and configuration.

The command "show vlan" is used to display detailed information about all VLANs on the switch. It provides a comprehensive view of the VLAN configuration, including the VLAN ID, name, and associated ports. This command is useful for troubleshooting VLAN-related issues and verifying the VLAN setup on the switch.

The correct answer is "Each port is associated with a specific VLAN," "Manual config for port assignments required," and "Requires admin interaction when users move." This is because in a static VLAN, each port is manually assigned to a specific VLAN, requiring manual configuration for port assignments. Additionally, when users move, the admin needs to interact and make necessary changes to the VLAN configuration. This results in less administrative overhead when users are moved, but also requires admin interaction for these changes.

Port security cannot be configured on trunk interfaces because port security is used to restrict access to a specific MAC address on an interface, which is not applicable to trunk interfaces that carry multiple VLANs. The native VLAN must be the same on both ends of the trunk to ensure proper communication between the switches. If the native VLANs are different, it can cause VLAN mismatch issues.

The ports are inactive because the Marketing VLAN has been deleted, so there is no VLAN configuration on those ports. However, the ports will remain part of the Marketing VLAN until they are reassigned to another VLAN.

The correct answers for this question are "Less Admin overhead when users are moved," "Config based on database," and "Ports work out their own config."

"Less Admin overhead when users are moved" refers to the fact that with dynamic VLANs, the VLAN assignment for a user can be automatically updated when they move to a different physical location, reducing the need for manual intervention by network administrators.

"Config based on database" means that the VLAN configuration information is stored in a database, making it easier to manage and update the VLAN assignments for different ports.

"Ports work out their own config" indicates that the ports in the network can dynamically determine the appropriate VLAN configuration based on the information stored in the database, without requiring manual configuration for each individual port.

The normal range of VLANs, which is from 1 to 1005, includes reserved VLANs for Token Ring and FDDI. This means that these VLANs are specifically designated for use with Token Ring and FDDI networks. Additionally, the normal range includes all ports by default, meaning that all ports on a device are automatically members of VLANs within this range. The answer provided correctly identifies both of these characteristics of the normal range of VLANs.

Based on the given information, Host 1 has an IP address of 192.168.1.22/28 and is connected to port 0/4. Host 2 has an IP address of 192.168.1.33/28 and is connected to port 0/5. Host 3 has an IP address of 192.168.1.30/28 and is connected to port 0/6.

Since all three hosts have IP addresses in the same subnet (192.168.1.0/28), they should be able to communicate with each other. Therefore, Host 1 can ping Host 3 successfully. However, Host 1 and Host 2 have different IP addresses and are not connected directly, so Host 1 cannot ping Host 2. Similarly, Host 2 cannot ping Host 3 as they are not directly connected.

The VLAN range 1006-4094 is considered the extended range, which means it is used for special purposes and is not learned by VTP (VLAN Trunking Protocol). This range is not included in the default management VLAN and does not contain any reserved VLANs for Token Ring and FDDI. Additionally, all ports are a member of this VLAN range by default.
