[All 1z0-599 Questions]

A customer has a web application with HTTP Sessions that need to be replicated to a backup site that is more than 100 miles away from the primary site, connected over the Internet.
Which type of session replication in WebLogic is recommended?

  • A. MAN Replication
  • B. WAN Replication
  • C. Synchronous Replication
  • D. Asynchronous Replication
  • E. Database Replication

Suggested Answer: D 🗳️
WAN HTTP Session State Replication
Resources in a wide area network (WAN) are frequently spread across separate geographical regions. In addition to requiring network traffic to cross long distances, these resources are often separated by multiple routers and other network bottle necks. Network communication in a WAN generally has higher latency and slower interconnect.
Slower network performance within a WAN makes it difficult to use a synchronous replication mechanism like the one used within a MAN. WebLogic Server provides failover across clusters in WAN by using an asynchronous data replication scheme.
Note:

HTTP Session State Replication -
Weblogic Server uses two methods for replicating HTTP session state across clusters: in-memory replication
* Using in-memory replication, WebLogic Server copies a session state from one server instance to another. The primary server creates a primary session state on the server to which the client first connects, and a secondary replica on another WebLogic Server instance in the cluster. The replica is kept up-to-date so that it may be used if the server that hosts the servlet fails.
* JDBC-based persistence
In JDBC-based persistence, WebLogic Server maintains the HTTP session state of a servlet or JSP using file-based or JDBC-based persistence.
JDBC-based persistence is also used for HTTP session state replication within a Wide Area Network (WAN).
