The correct answer is "switchport port-security maximum 10." This command sets the maximum number of MAC addresses allowed on a switchport to 10. This helps to prevent unauthorized devices from connecting to the network by limiting the number of devices that can be connected to a specific port.

To span multiple switches with multiple VLANs, a trunk is required. A trunk is a network link that carries traffic for multiple VLANs between switches. It allows for the transmission of VLAN-tagged frames across switches, ensuring that each switch can correctly identify and forward traffic to the appropriate VLAN. Trunks use protocols such as IEEE 802.1Q to tag VLAN information onto Ethernet frames, enabling the switches to differentiate between VLANs and maintain their integrity across the network. Without a trunk, VLANs would be isolated to individual switches, limiting their ability to communicate with each other.

When you delete a VLAN from a VTP domain, you should perform the change on a switch in VTP server mode. This is because VTP server mode is responsible for managing and propagating VLAN information to other switches in the domain. By deleting the VLAN on a switch in VTP server mode, the change will be communicated to all other switches in the VTP domain, ensuring that the VLAN is removed from their configurations as well.

STP provides a loop-free network by placing some ports in the blocking state. This means that certain ports on the switches are temporarily disabled, preventing them from forwarding traffic. By selectively blocking ports, STP ensures that there are no loops in the network, which can cause broadcast storms and degrade network performance. The blocked ports are only activated when there is a failure in the network, ensuring that redundant paths are available if needed, but without creating loops.

The "show vian" command displays the names of the VLANs and the ports assigned to those VLANs. This command provides information about the VLAN configuration on a network device, allowing administrators to see which VLANs are configured and which ports are assigned to each VLAN.

The "show vtp status" command would be used to determine if the switch is in VTP transparent mode. This command displays the VTP configuration information, including the VTP mode. By checking the mode, you can determine if the switch is in transparent mode, which means it does not participate in VTP updates and does not synchronize its VLAN configuration with other switches.

STP (Spanning Tree Protocol) selects the designated port on a segment based on the lowest-cost path to the root bridge. The root bridge is the bridge with the lowest bridge ID in the network. By selecting the lowest-cost path to the root bridge, STP ensures that the designated port is on the most efficient path for forwarding traffic. This helps to prevent loops and ensures that the network operates with optimal performance.

The state of a root port in STP is forwarding. In Spanning Tree Protocol (STP), the root port is the port on a non-root bridge that offers the shortest path to the root bridge. It is responsible for forwarding data packets towards the root bridge. The forwarding state allows the port to actively send and receive data packets, ensuring efficient communication within the network.

A broadcast storm refers to the excessive flooding of broadcast packets in a network, causing a loop and overwhelming the network's resources. This can result in degraded network performance and can even lead to a network outage.

The correct answer is one because a switch can only belong to a single VTP (VLAN Trunking Protocol) domain at a time. VTP allows for the synchronization of VLAN information across multiple switches in a network, but each switch can only be part of one domain.

The correct answer is "show spanning-tree." This command is used to display the spanning-tree configuration status of the ports on a Cisco Catalyst 2960 Series Switch. It provides information about the spanning-tree protocol, including the root bridge, port roles, and port states. This command is commonly used for troubleshooting and monitoring the spanning-tree topology on the switch.

The correct answer is "vtp mode transparent" because this command is used to configure a switch in transparent mode in the VTP domain "switchlab". In transparent mode, the switch does not participate in VTP updates and does not advertise its VLAN configuration to other switches. This mode is typically used when you want to manually configure VLANs on a switch without affecting the VTP domain.

A VMPS (VLAN Membership Policy Server) maps to VLAN assignments based on MAC addresses. This means that the VMPS uses the MAC address of a device to determine which VLAN it should be assigned to. By associating MAC addresses with specific VLANs, the VMPS can effectively manage VLAN membership and ensure that devices are placed in the correct VLAN based on their MAC address.

The command "Router(config-if) # encapsulation dot1Q 50" correctly assigns a subinterface to VLAN 50 using 802.1Q trunking. This command specifies the encapsulation type as dot1Q, which is the standard for VLAN tagging, and assigns the VLAN ID as 50.

The default VTP mode on a Cisco Catalyst switch is "server". In this mode, the switch can create, modify, and delete VLANs and share this information with other switches in the VTP domain. It also synchronizes VLAN information received from other switches and can advertise this information to other switches in the domain. The server mode is typically used in larger networks where multiple switches need to be managed and configured centrally.

A nondesignated port in STP is in the blocking state. This means that the port is not part of the active network path and does not forward any frames. It is essentially "blocked" from participating in the network communication to prevent loops and ensure a stable network topology. The blocking state helps in preventing network congestion and ensures that only designated ports are actively forwarding traffic.

STP automatically reconfigures switch or bridge ports when the network topology changes. This means that when there is a change in the way the devices are interconnected or when a new device is added or removed from the network, STP will dynamically adjust the forwarding paths to prevent loops and ensure a stable network. This automatic reconfiguration is essential for maintaining network stability and preventing broadcast storms or other network issues that can arise from changes in the topology.

In the listening state, a port in Spanning Tree Protocol (STP) is able to receive and process Bridge Protocol Data Units (BPDUs) to determine the network topology. However, it does not yet populate its MAC table, which means it does not learn or store MAC addresses. The listening state is a transitional state before the learning state, where the port starts populating its MAC table. Therefore, the correct answer is that the port is able to check for BPDUs, but not yet populate its MAC table.

VTP (VLAN Trunking Protocol) minimizes misconfigurations and configuration inconsistencies in a switched network. It does this by allowing for centralized management of VLAN configurations, ensuring that all switches in the network have consistent VLAN information. This helps to prevent errors and inconsistencies that can occur when manually configuring VLANs on individual switches. By minimizing misconfigurations and inconsistencies, VTP improves network reliability and reduces the chances of network issues caused by incorrect VLAN configurations.

The lowest-cost path from the nonroot bridge to the root bridge is through the root port. The root port is the port on the nonroot bridge that offers the shortest path to reach the root bridge. It is the port that receives the best BPDU (Bridge Protocol Data Unit) information from the root bridge, indicating the lowest cost path. This port is responsible for forwarding traffic towards the root bridge.

Unicast frames are not flooded to all ports except the source port on a switch. Frames with a known destination address are not flooded either, as they can be forwarded directly to the intended recipient. However, multicast frames, broadcast frames, and frames with an unknown destination address are flooded to all ports except the source port to reach all potential recipients.

802.1Q is used to allow switches to share a trunk link with nontrunking clients, which means that multiple VLANs can be transmitted over a single physical link. It also provides trunking between Cisco switches and other vendor switches, allowing for interoperability between different network equipment.

The term that describes multiple copies of a frame arriving on different ports of a switch is "broadcast storm". A broadcast storm occurs when a switch receives a broadcast frame and forwards it out of all its ports, causing each switch in the network to receive and forward the same frame again. This can lead to network congestion and performance issues. Spanning Tree Protocol (STP) helps prevent broadcast storms by blocking redundant paths in a network.
