Referring to the exhibit, what is the minimum number of LSPs required to support all four networks?

    Correct Answer: D

    To support all four networks, you need to establish bi-directional LSPs (Label Switched Paths) between the networks. You have four networks, each one needing a direct or indirect LSP to communicate with the other networks. For a full mesh, the minimal LSPs required are given by the formula n(n-1)/2 for unidirectional LSPs and n(n-1) for bidirectional LSPs, where n is the number of networks. In this case, you can optimize to have one LSP from Network 1 to each of Network 3 and 4, and one LSP from Network 2 to each of Network 3 and 4, resulting in four LSPs. Hence, the minimum number of LSPs required to support all four networks is four.
