In STP, each port on a network switch has an associated cost, and this cost is based on the speed of the link. The faster the link, the lower the cost. The cost values are standardized by the IEEE. Here are some common cost values:
10 Mbps (Ethernet): Cost = 100
100 Mbps (Fast Ethernet): Cost = 19
1 Gbps (Gigabit Ethernet): Cost = 4
10 Gbps (10 Gigabit Ethernet): Cost = 2
So answ is C
In IEEE Spanning Tree Protocol (STP) calculations, the link cost for a Fast Ethernet interface is typically set to 19. Therefore, the correct answer is:
C. 19
STP uses link costs to determine the best path in a network topology to prevent loops. Fast Ethernet has a default link cost of 19, while Gigabit Ethernet has a default link cost of 4. The link cost is used to determine the root bridge and the best path for data traffic within the spanning tree topology.
vceUP says its 100. "The IEEE standard for link cost for a Fast Ethernet interface is 100, and for a Gigabit Ethernet interface is 19. These values are based on the bandwidth of the interface, with lower values indicating a higher-bandwidth interface."
chatGPT says its 19. "In Spanning Tree Protocol (STP) calculations, the IEEE link cost for a Fast Ethernet interface is typically 19. The link cost is a value assigned to each port on a network switch based on the speed of the interface. It is used by STP to determine the path cost and select the best path to the root bridge.
Here are the link cost values commonly used in STP calculations:
10 Mbps Ethernet: 100
100 Mbps Fast Ethernet: 19
1 Gbps Gigabit Ethernet: 4
10 Gbps 10 Gigabit Ethernet: 2
40 Gbps 40 Gigabit Ethernet: 1
100 Gbps 100 Gigabit Ethernet: 1
So, for a Fast Ethernet interface (100 Mbps), the IEEE link cost is 19."
For a Fast Ethernet interface, the IEEE (Institute of Electrical and Electronics Engineers) has assigned a link cost of 100. This means that, when calculating the optimal path through the network, STP will favor slower links over Fast Ethernet links because they have a lower cost.
