1Z0-058 Question #114: Real Exam Question with Answer & Explanation

You installed the Oracle Grid Infrastructure on a four-node cluster before discussing the network requirements with the network administrator who was on holiday. You created a single scan named mydb-scan.myclust.example.com by adding this name to the /etc/hosts file. As a result, the Grid Infrastructure has four node listeners and node VIP but only a single SCAN listener and SCAN VIP. The network administrator has returned and modified the corporate DNS server to associate three IP addresses with the mydb-scan.myclust.example.com scan name. The SCAN VIPs are on the same network as the node VIPs. You now must replace the single SCAN VIP and listener with three of each for high availability purposes and make certain that the SCANs and listeners are active. Which procedure will do this properly if run as the root user?
