After Oracle Grid Infrastructure has been installed, you should take a few moments to verify the installation. Which two actions would be useful in verifying the installation?
A.
Run the crsctl status resource �t command to confirm that all necessary cluster resources are online.
B.
Use the operating system utilities to verify that your SCAN addresses are being properly resolved.
C.
Start Oracle Enterprise Manager and check all monitored targets.
D.
Run the cluvfy comp nodecon �n all �verbose command to verify the entire Grid Infrastructure installation.
A and B are the correct ones
you should check SCAN addresses resolving before installation, so D looks like right choice….but why not C …
in “D60488GC11 Oracle 11g: RAC and Grid infrastructure administration accelerated” materials find that A and B looks like right answers..
I think “A” and “D” are right answer. Because “crsctl” with “status resource -t” is usefull to verify cluster resource status that they are running properly. And “cluvfy” is used to verify system configuration to all nodes of cluster for per-installation and post-installation.
As far as I remembered, SCAN is checked due to running “cluvfy”.
