Which commands must you use to determine the cluster node type (role) of racdbnode2 and change the role to Leaf node of the same node?
A. [GRID]>srvct1 config vip -node racdbnode2
[GRID]>crsct1 get node role config
#Change to root
#u
password: XXXX
[GRID]>crsct1 config -i node role leaf
B. [GRID]>srvct1 config vip -node racdbnode2
[GRID]>crsct1 get node role config
[GRID]>crsct1 set node role leaf
[GRID]>crsct1 stop crs
[GRID]>crsct1 start crs
C. [GRID]>srvct1 config vip -node racdbnode2
[GRID]>crsct1 get node role config
#Change to root
#u
password: XXXX
[GRID]>crsct1 set node role leaf
[GRID]>crsct1 stop crs
[GRID]>crsct1 start crs
D. [GRID]>srvct1 set vip -node racdbnode2
[GRID]>crsct1 modify node role config
#Change to root
