To solve this question, the user needs to know the characteristics of a peer-to-peer network.
The statement "Peer-to-Peer network are not flexible" is not entirely true. Peer-to-peer networks are actually flexible in nature since they are decentralized and do not rely on a central server. Each node in a peer-to-peer network can act as both a client and a server, allowing for greater flexibility in terms of sharing resources and data. Moreover, peer-to-peer networks can also be easily expanded or reduced in size, making them more adaptable to changes in network traffic.
