1Z0-593 Question #46: Real Exam Question with Answer & Explanation

The correct answer is C. One per node in the cluster. Oracle Clusterware requires a cluster interconnect configured for inter-node communication. The Oracle Clusterware interconnect is a non-traditional interconnect and should be considered, in shared global cache applications, such as Oracle RAC, to be an I/O subsystem for inter-no

Question

How many Oracle Clusterware interconnect networks are required and why?

Options

AOnly one; minimum requirement
BTwo; redundancy is required
COne per node in the cluster
DOne per database in the cluster

Explanation

Oracle Clusterware requires a cluster interconnect configured for inter-node communication. * The Oracle Clusterware interconnect is a non-traditional interconnect and should be considered, in shared global cache applications, such as Oracle RAC, to be an I/O subsystem for inter-node global cache buffer transfers with the latency and bandwidth requirements of high performance cluster computing. * The interconnect network is a private network using a switch (or multiple switches) that only the nodes in the cluster can access. Oracle Clusterware requires that you connect the nodes in the cluster to a private network by way of a private interconnect. The private interconnect is a separate network that you configure between cluster nodes. The interconnect used by Oracle RAC is the same interconnect that Oracle Clusterware uses. This interconnect should be a private interconnect, meaning it is not accessible to nodes that are not members of the cluster.
