Question 1

You want to change an existingOracle Clusterware standard Cluster to an Oracle Flex Cluster Thereis Grid Naming Service (GNS) and Flex ASM configured right now.In what order do you need to take the following steps?
1.StopOracle Clusterware 2.Determine the current mode of thecluster 3.Ensure that the GNSisconfigured with a fixed VIP. 4.Change the mode of the cluster to be an Oracle Flex Cluster. 5.Use theOracle Automatic Storage Management Configuration Assistant (ASMCA) to
enable Oracle Flex ASMinthe cluster 6.Start Oracle Clusterware

A. 1, 2,3, 4,5,6

B. 1,2,3,5,4,6

C. 2,3,5, 4, 1,6

D. 2,3,4,5,1,6

Correct Answer: D

Question 2

What device path do you have to specify in ASM, if you want to use the multipath device?
/dev/sdd = first path
/dev/sdd = second path
/dev/multipatha = path of the multipath OS driver

A. /dev/sdc as disk group and /dev/sdd as failure group.

B. Only /dev/multipatha is enough.

C. You need to specify all the three devices and only then ASM will know this is a multipath device.

D. Only /dev/sdc is enough, because asmlib knows it is a multipath device.

Correct Answer: B
