Which two statements are true about resources defined by an administrator and registered with Oracle 12c Clusterware for high availability?
A.
A policy-managed resource can be started manually using crsctl.
B.
A policy-managed resource can be started manually using srvctl.
C.
Resource dependencies are automatically set when using a policy-managed resource.
D.
An administrator-managed resource can be started manually using crsctl.
E.
An administrator-managed resource can be started manually using srvctl.
F.
The action script is automatically set when using a policy-managed resource.
Explanation:
A: With policy-based management, administrators specify the server pool (excluding the Generic and Free pools) in which the servers run. For example, a
database administrator uses SRVCTL to create a server pool for servers hosting a database or database service. A clusterware administrator uses CRSCTL to
create server pools for non-database use, such as creating a server pool for servers hosting an application.
E: Administrator-managed resources refer to databases. You must use SRVCTL to create server pools that host Oracle databases. You must use CRSCTL to
create server pools that host non-database resources such as middle tiers and applications.

A,D correct answers
An administrator-managed & Policy-managed resource can be started manually using CRSCTL
I think that “E” is wrong because of this: “To configure ”Oracle resources”, use the server control utility, SRVCTL, which provides you with all configurable options.”
https://docs.oracle.com/database/121/CWADD/crschp.htm#CWADD91281
And if i’m speaking about application resources…
The page in the link above has 73 references to crsctl and only 5 references to srvctl.

9 – Making Applications Highly Available Using Oracle Clusterware
“A” This is right!
“B” and “D” is wrong, srvctl is for “Oracle resources” not “application features”…
“E” this is right!
“C” and “F” I did not find anything like this in the documentation
“Notes:
Oracle Clusterware commands prefixed with crs_ are deprecated with this release. CRSCTL commands replace those commands. See Appendix E, “Oracle Clusterware Control (CRSCTL) Utility Reference” for a list of CRSCTL commands and their corresponding crs_ commands.
Do not use CRSCTL commands on any resources that have names prefixed with ora (because these are Oracle resources), unless My Oracle Support directs you to do so.
To configure Oracle resources, use the server control utility, SRVCTL, which provides you with all configurable options.”
“Server Pools and Policy-Based Management
With policy-based management, administrators specify the server pool (excluding the Generic and Free pools) in which the servers run. For example, a database administrator uses SRVCTL to create a server pool for servers hosting a database or database service. A clusterware administrator uses CRSCTL to create server pools for non-database use, such as creating a server pool for servers hosting an application.”
“How Server Pools Work
…
You manage server pools that contain Oracle RAC databases with the Server Control (SRVCTL) utility. Use the Oracle Clusterware Control (CRSCTL) utility to manage all other server pools. Only cluster administrators have permission to create top-level server pools.
Database administrators use the Server Control (SRVCTL) utility to create and manage server pools that will contain Oracle RAC databases. Cluster administrators use the Oracle Clusterware Control (CRSCTL) utility to create and manage all other server pools, such as server pools for non-database applications. Only cluster administrators have permission to create top-level server pools.”
“Starting Application Resources
Start and stop resources with the crsctl start resource and crsctl stop resource commands. Manually starting or stopping resources outside of Oracle Clusterware can invalidate the resource status. In addition, Oracle Clusterware may attempt to restart a resource on which you perform a manual stop operation.
To start an application resource that is registered with Oracle Clusterware, use the crsctl start resource command. For example:
$ crsctl start resource myApache”
So you mean A and D are correct?
