Which three statements are true about Server Categorization in Oracle 12c Clusterware?
A.
All server attributes that may be used to determine the server category are discovered automatically by
Oracle Clusterware.
B.
Different Hub nodes in a flex cluster may belong to separate administrator-defined categories.
C.
All hub nodes in a flex cluster belong to the same Oracle-supplied category.
D.
A server may be added to only one category using the crsctl utility.
E.
All leaf nodes in a flex cluster belong to the same Oracle-supplied category.
F.
All server attributes used for categorization are administrator modifiable.
Explanation:
CE: The SERVER_CATEGORY is the name of a registered server category, used as part of server
categorization. Oracle Clusterware standard Clusters and Oracle Flex Clusters have default categories of hub
and leaf.
F: Server Category Attributes
You define servers into named categories, and assign attributes that define servers as members of that
category. Some attributes that you can use to define members of a category describe the state conditions for
the server, and others describe the physical characteristics of the server. You can also create your own
characteristics to define servers as members of a particular category.
