What is an active-active?
Also known as Dual Active Clustering, Active/Active clustering means that independent nodes in a networked server cluster have access to their own replicated database server. Since the databases are replicated, it mimics having only one instance of the application, allowing data to stay in sync.
What is active-active disaster recovery?

What are the two configurations of failover system?
The most common high availability (HA) configurations are active-active and active-standby or active-passive. These implementation techniques both improve reliability, but each achieves failover in a different way.

How does active/active firewall work?
Active/Active — Both firewalls in the pair are active and processing traffic and work synchronously to handle session setup and session ownership. Both firewalls individually maintain session tables and routing tables and synchronize to each other. Active/active HA is supported in virtual wire and Layer 3 deployments.
How do you check if the cluster is active-active or active-passive?
Like the active-active cluster configuration, an active-passive cluster also consists of at least two nodes. However, as the name “active-passive” implies, not all nodes are going to be active. In the case of two nodes, for example, if the first node is already active, the second node must be passive or on standby.

What is the difference between failover and high availability?
High Availability and Failover. A part of high availability is failover which we define as the ability for client connections to migrate from one server to another in event of server failure so client applications can continue to operate. …

What is active active database?
