In a full mesh topology with 7 nodes, how many direct connections are required?
Correct Answer:
C. 21
Explanation:
In a full mesh topology, every node is directly connected to every other node in the network. To determine the total number of direct connections (links) required for a network with n nodes, the formula is n(n-1)/2. For a network with 7 nodes, the calculation is 7(7-1)/2, which equals 7(6)/2 or 42/2. Therefore, 21 direct connections are required to ensure every node has a dedicated point-to-point link to all other nodes.
