For which three entities can the “what-if” command evaluation be used to determine the impact of clusterware management operations in Oracle 12c Clusterware? (Choose three.)
A.
Pluggable Databases (PDBs)
B.
administrator-defined resources
C.
local resources
D.
database transactions
E.
cluster resources
I think Correct: A, B, E
Using the crsctl eval command, application administrators can perform what-if command evaluation to test the effect of starting, stopping, relocating, modifying, or adding cluster resources.
What-If response plans available for Resources, Server Pools, Servers, Policies, and Server Categories
I can’t find administrator-defined resources in Oracle document.
Clusterware admin class material says:
There are three resource types, local resource, cluster resource, and generic application.
I pick ACE, but not too sure on A Pluggable Databases.
I think its ABE

https://www.toadworld.com/platforms/oracle/w/wiki/11724.oracle-clusterware-12c-what-if-command-evaluation-part-ii
for me the correct answer should be B,C,E
what-if command is about clusterware resources, PDBs and database transaction are not part of oracle clusterware…
Administrators can use the Oracle Clusterware 12c What-If command
to predict Oracle Clusterware’s response to a hypothetical planned or unplanned event. Oracle
Clusterware 12c has the ability to react to events in the system and produce a response action plan.
This action plan consists of a series of resource state transitions and/or server pool reconfigurations.
What-If response plans are available for the following event categories

E correct
“TYPE == cluster_resource”: This filter limits Oracle Clusterware to relocate only resources of cluster_resource type
Correct: A, B and E
