You are working as a network administrator for an organization. You are to set up a fully-meshed Frame Relay network to connect four remote branch sites. How many PVCs are required in this network?
  1. 12
  2. 16
  3. 6
  4. 8
Explanation
Answer - C - The number of PVCs required to connect four remote branch sites is 6.

Key Takeaway: The formula for calculating the number of links to achieve a full mesh is N (N−1)/2, where N is the number of locations. In this case there are 4 locations, so we will need 4(3)/2 = 6 links for the full mesh.
