第 19 号 Which two actions guarantee that time is synchronized properly on all nodes in a cluster after installing Oracle Grid Infrastructure 19c? (Choose two.)

第 21 号 Examine these descriptions of ASM instance shutdown behavior:
1) The ASM instance shuts down immediately without an orderly dismount of disk groups.
2) Active SQL statements are allowed to complete before an orderly dismount of all disk groups occurs and then the ASM instance shuts down without waiting for connected sessions to disconnect. If any ASM clients are connected to the instance, then the shutdown returns an error.
3) Active SQL statements are allowed to complete before an orderly dismount of all of disk groups occurs and then the ASM instance shuts down after waiting for connected sessions to disconnect. If any ASM clients are connected to the instance, then the shutdown returns an error.

第 24 号 Which two statements are true concerning diagnostic components and requirements of Oracle 19c Clusterware? (Choose two.)

The clusterware log files are stored inside the Grid Infrastructure Management Repository database used by the cluster health monitor

The diagcolleccion.pl script must be run from the Grid home directory as the arid infrastructure owner.

There is one ologgerd service for the cluster health monitor (CHM) on each cluster node regardless of cluster size.

The oclumon utility may be used to get and set parameters for the cluster health monitor (CHM) repository.

There is one osysmond service for the cluster health monitor (CHM) on each cluster node regardless of cluster size.

NO.25 Which two statements are true about server categorization in Oracle 19c Clusterware? (Choose two.)

Different nodes in a cluster may belong to separate administrator-defined categories.

All nodes in a cluster belong to the same Oracle-supplied category.

A server may be added to only one category using the crsctl utility.

All server attributes that may be used to determine the server category are discovered automatically by Oracle Clusterware.

All server attributes used for categorization are administrator modifiable.

Server categories can only be used for nodes running an application server.

NO.26 Examine this command executed on the first node of a four-node cluster:
$ < DATABASE_ORACLE_HOME >/OPatch/opatch apply 33575673
What does this command do?

It applies a patch to one oracle home only on the first cluster node.

It applies a patch to one database ORACLE home on alll cluster nodes.
