A. comp – To show valid components with description
B. stage – To list pre and post checks of stages
C. asm – To list valid disks available
D. dbstat – To list number of instances available online
Answer: AB

Explanation:
A: To verify the minimal system requirements on the nodes prior to installing Oracle Clusterware
or Oracle RAC, use the sys component verification command as follows:
cluvfy comp sys [ -n node_list ] -p { crs | database } } [-r { 10gR1 |
10gR2 | 11gR1} ] [ -osdba osdba_group ] [ -orainv orainventory_group ]
[-verbose]
B: To verify whether your system meets all of the criteria for an Oracle Clusterware installation,
use the -pre crsinst command for the Oracle Clusterware installation stage as follows:
cluvfy stage -pre crsinst -n node_list
[ -c ocr_location ] [-r { 10gR1 | 10gR2 | 11gR1} ][ -q voting_disk ]
[ -osdba osdba_group ]
[ -orainv orainventory_group ] [-verbose]

QUESTION 5
You want to set full debugging for the communications and resource management components
for the CRS module on nodes host01 and host03. How can you accomplish this?
A. crsctl set log CRS “CRSCTL: 5, CRSCOMM: 5” -nodelist host01, host03
B. crsctl lsmodules crs set log CRSCTL: 5, CRSCOMM: 5 -nodelist host01, host03
C. srvctl set log -m CRSCTL5, CRSCOMM 5 -n host01, host03
