Question #: 90
Topic #: 1
[All 1z0-133 Questions]

Identify two advantages of using a Single Client Access Name (SCAN) when configuring a GridLink data source. (Choose two.)

  • A. The Fast Connection Failover (FCF) pattern, which allows rapid failure detection, is enabled
  • B. The more sophisticated runtime connection load balancing (RLCB) is used; without SCAN, load balancing reverts to a simple round-robin scheme
  • C. SCAN is required for the GridLink data source to use an XA driver
  • D. The database URL is shorter because it contains one SCAN alias and port as opposed to a host and port for each RAC node
  • E. The data source configuration does not need to be updated when new nodes are added to the RAC cluster
