At least one device maintains multiple connections to other devices
Correct Answer
Partial MeshExplanation
A partial mesh network is a type of network where at least one device maintains multiple connections to other devices. In this network topology, not all devices are directly connected to each other, but there are some devices that have multiple connections. This allows for redundancy and improved fault tolerance in the network, as there are alternative paths for data transmission if one connection fails. The partial mesh topology strikes a balance between the fully connected mesh network and the less connected star or bus networks.Rate this question:

- B.
IP uses relational addressing
- C.
IP delivers data reliability
- D.
IP operates at Layer 2 of the TCP/IP stack and OSI model
- E.
IP does not provide any recovery functions
- F.
IP delivers data on a best effort basis
Correct Answer(s)
A. IP is a connectionless protocol
E. IP does not provide any recovery functions
F. IP delivers data on a best effort basisExplanation
IP is a connectionless protocol, meaning that it does not establish a dedicated connection before transmitting data. It uses relational addressing to identify devices on a network. However, IP does not provide any recovery functions, so it does not guarantee the delivery of data.
