An engineer is designing a disaster recovery solution. In the event of a node failure, the solution should either direct all of the traffic to another node, or load-balance the traffic across the remaining nodes.
Which solution should be implemented in the design?
The active/active solution fits the requirement of either directing all traffic to another node or load-balancing the traffic across the remaining nodes. In an active/active configuration, all nodes are actively handling traffic simultaneously. If one node fails, the remaining active nodes can continue handling the traffic, ensuring high availability and load balancing.
An Active-Passive solution involves a primary node actively handling traffic, and a secondary node in standby mode. If the primary node fails, the secondary node takes over, to either handle all traffic or load-balancing it across other nodes.
