문제 #1

Which three statements are true regarding ASM on a four-node cluster? (Choose three.)

A. A database instance on a node uses an ASM instance as an I/O server when requesting I/O to diskgroups.
B. A database instance on a node can be a client of an ASM instance running on any node.
C. A database instance on a node can only be a client of an ASM instance running on the same node.
D. An ASM instance and database instances can coexist on the same node.
E. ASM Cluster File System (ACFS) can be deployed on any nodes.
F. A database instance on a node cannot be a client of an ASM instance running on other nodes.

문제 #2

A Java application using thick JDBC connections will soon be deployed, and you must configure a RAC database to support highly available connections.
Broken connections must be re-established as quickly as possible.
Which feature will support this requirement?

A. Fast Connection Failover (FCF)
B. Transparent Application Failover (TAF)
C. Fast Connection Failover (FCF) with Transparent Application Failover (TAF)
D. Transparent Application Failover (TAF) using Fast Application Notification (FAN)

문제 #3

Your four-node cluster runs Oracle 19c Clusterware and supports a mix of RAC databases from Oracle 10g Release 2 to Oracle 19c.
All databases have one or more services defined.
The Oracle 10g Release 2 database clients connect to the database instances using the public VIP.
The Oracle 11g Release 2, 12c Release 1, and 19c clients connect to the database instances using the Single Client Access Name (SCAN).
You must change the public VIPs.
Which three actions must be performed to change the VIPs on host01, the first node in the cluster? (Choose three.)

A. Use oifcfg setif to stop the VIP on host01.
B. Use srvctl modify nodeapps to change the VIP on host01.
C. Use srvctl start vip to start the VIP on host01.
D. Use srvctl stop vip to stop the VIP on host01.
E. Use oifcfg setif to start the VIP on host01.

문제 #4

Which two statements are true concerning Oracle 19c Clusterware-managed application VIPs? (Choose two.)

A. An application VIP is created on the interconnect network by the crsccl utility.
B. An application VIP can be created with the crsccl utility.
C. An application VIP is created on the default network by the appvipcfg utility.
D. Application VIPs do not fail over to surviving cluster nodes when the node hosting the VIP fails.
E. If an application sends messages to be displayed and sets the display variable, then an application VIP is required.

문제 #5

Which four statements are true concerning the upgrading of Oracle Grid Infrastructure 19c? (Choose four.)

A. The cluster verification utility cluvfy.sh can generate fixup scripts to run on all nodes of the cluster.
B. The upgrade must be done out-of-place.
C. The oracle home environment variable must be set to the Grid Infrastructure home directory in the installation owner's environment.
D. The oracle SID environment variable must be set to the SID of the ASM instance in the installation owner's environment.
E. The upgrade must be done in-place.
F. Upgrade validation may be done using the Oracle Universal Installer which in turn invokes the built-in cluster verification utility.
G. The cluster verification utility cluvfy.sh can verify that the cluster is ready for an upgrade.
