Q24. Which two software components are central to providing the performance benefits delivered by an Exalogic machine?
A. WebLogic Server
B. Coherence
C. SOA Suite
D. Oracle Database
E. Oracle VM
Answer: A,B
Explanation: Coherence provides replicated and distributed (partitioned) data management and caching services on top of a reliable, highly scalable peer-to-peer clustering protocol. Coherence has no single points of failure; it automatically and transparently fails over and redistributes its clustered data management services when a server becomes inoperative or is disconnected from the network. When a new server is added, or when a failed server is restarted, it automatically joins the cluster and Coherence fails back services to it, transparently redistributing the cluster load. Coherence includes network-level fault tolerance features and transparent soft re-start capability to enable servers to self-heal.
