3.3 Explain high availability and disaster recovery concepts and summarize which is the best solution Flashcards
Name the method of fault tolerance used when a group of servers, consisting of redundant nodes, prevents disruption of network services.
Link aggregation
Clustering
Load balancing
NIC teaming
A cluster is a group of servers, each of which is referred to as a node, that provides redundancy and fault tolerance for critical applications.
A load balancer can switch client traffic to alternative processing nodes, reducing bottlenecks and allowing for failover services in the event of a host or network route going down.
Link aggregation is a method of fault tolerance that involves combining two or more separate cabled links into a single logical channel.
Link aggregation signifies combining two or more separate cabled links into a single logical channel. When done from the host end, this is called NIC teaming.
