Select the correct statement(s) regarding "full and "partial" mesh networks.

a. Adding new nodes to a full mesh network is simpler than adding new nodes to a partial mesh network

b. When designing a partial mesh network, the user's availability and reliability requirements help to determine the number of links needed between nodes

c. Every node in a partial network is a single point of failure, therefore most service providers avoid implementing partial mesh networks

d. Implementing partial mesh networks requires that links from a node connect to every other node in the network
