The customer is still not convinced about the advantages of using node VIPs. Which is the most
important point that will convince him about why VIPs are used in Oracle RAC 12cR1 environments?

A.
It is very convenient as whenever a node/interface/network related to the node VIP falls, the VIP
can fail to another node and the failed over VIP can start accepting connections from the new node
avoiding connection failures.

B.
This is needed as whenever a node/interface/network related to the node VIP fails, clients that
attempt to connect to the VIP address receive a rapid connection-refused error Instead of waiting
for TCP connect timeout messages. This helps for a quicker failure detection and resolution.

C.
It is needed as whenever the node/interface/network related to the VIP fails, nothing happens
and node VIP never fails to any other node and stays stable.

D.
Configuring VIP is optional and not needed in an Oracle RAC 12cR1 configuration.

If a node fails, then the VIP address fails over to another node on which the VIP address can accept TCP connections, but it does not accept connections to the Oracle database. Clients that attempt to connect to a VIP address not residing on its home node receive a rapid connection refused error instead of waiting for TCP connect timeout messages.
