CAN is multi-master network?

What is multi-master model?
Multi-Master Model A multi-master enabled database, such as the Active Directory, provides the flexibility of allowing changes to occur at any DC in the enterprise, but it also introduces the possibility of conflicts that can potentially lead to problems once the data is replicated to the rest of the enterprise.
How is multi master replication different from master slave replication?
Multi-master replication can be contrasted with master-slave replication, in which a single member of the group is designated as the “master” for a given piece of data and is the only node allowed to modify that data item. Other members wishing to modify the data item must first contact the master node.
Why do you need replication in PostgreSQL multiple slave?
Replication lets you perform analyses without affecting the operations of the master. You can use replication to scale out especially when you have a low number of writes and a high number of reads. In a single master multiple slave scenario, only one server (the master) is allowed to make changes to the data.
Can a slave be a slave to more than one master?
If each Master have a distinct Database that is mutually exclusive from other Master, you could have a Slave be a Slave to just one Master. Then, when all changes are posted, you would stop replication, run CHANGE MASTER TO command to point the Slave at a different Master.
How is multi master replication different from failover clustering?
Multi-master replication can also be contrasted with failover clustering where passive slave servers are replicating the master data in order to prepare for takeover in the event that the master stops functioning. The master is the only server active for client interaction.
