Oracle Database Administration 2019 Certified Professional — Question 9

Your four-node cluster runs Oracle 19c Clusterware and supports a mix of RAC databases from Oracle 10g Release 2 to Oracle 19c.
All databases have one or more services defined.
The Oracle 10g Release 2 database clients connect to the database instances using the public VIP.
The Oracle 11g Release 2, 12c Release 1, and 19c clients connect to the database instances using the Single Client Access Name (SCAN).
You must change the public VIPs.
Which three actions must be performed to change the VIPs on host01, the first node in the cluster? (Choose three.)

Answer options

Correct answer: A, D, E

Explanation

The correct actions are A, D, and E. Action A is necessary to start the VIP after the change, D is needed to modify the node applications to reflect the new VIP configuration, and E is required to stop the VIP before making changes. Option B is incorrect because oifcfg is not used for starting the VIP, and option C is not relevant as stopping the VIP must occur after the modification is made.
