1.	A subset of a network that includes all the routers but contains no loops is called ________(a) spanning tree(b) spider structure(c) spider tree(d) special treeThe question was posed to me during an interview for a job.My question is taken from Network Layer topic in portion OSI Model of Computer Network
Answer» Right option is (a) spanning tree Best explanation: Spanning tree protocol (STP) is a network protocol that creates a LOOP free logical topology for ethernet networks. It is a LAYER 2 protocol that runs on bridges and switches. The MAIN purpose of STP is to ENSURE that you do not create loops when you have redundant PATHS in your network.
