B. The upgrade must be done in-place.

C. The cluster verification utility cluvfy.sh can verify that the cluster is ready for an upgrade.

D. The oracle home environment variable must be set to the Grid Infrastructure home directory in the installation owner's environment.

E. The oracle SID environment variable must be set to the SID of the ASM instance in the installation owner's environment.

F. The upgrade must be done out-of-place.

G. The cluster verification utility cluvfy.sh can generate fixup scripts to run on all nodes of the cluster.

정답: A,C,D,G

문제2

문제3

Which statement is true concerning the installation of an Oracle Grid Infrastructure 19c patchset and its status during the installation?

A. When performing rolling patches, crsctl query crs softwareversion always displays the earliest version of the software running anywhere in the cluster.

B. When performing rolling patches, the vips for the node being patched are relocated to another node.

C. They can be applied in-place.

문제4

Secure Cluster Communication protects the cluster interconnect from common security threats when used together with Single Network Support. Secure Cluster Communication includes message digest mechanisms, protection against fuzzing, and uses Transport Layer Security (TLS) to provide privacy and data integrity between the cluster members.
Which statement is true about securing cluster interconnect communication?

A. Security for the cluster interconnect is invoked by auto-generated server certificates that will be assigned to each cluster node as part of a new Oracle Grid Infrastructure 19c deployment or an upgrade to Oracle Grid Infrastructure 19c.

B. Security for the cluster interconnect is invoked automatically as part of a new Oracle Grid Infrastructure 19c deployment or an upgrade to Oracle Grid Infrastructure 19c using an auto-generated encryption key that is stored locally on each node of the cluster in an Oracle Wallet and Database administrators or cluster administrators must provide a valid path for the Wallet file.

C. Security for the cluster interconnect is invoked automatically as part of a new Oracle Grid Infrastructure 19c deployment or an upgrade to Oracle Grid Infrastructure 19c and Database administrators or cluster administrators do not need to make any configuration changes for this feature.

D. Database administrators or cluster administrators must provide an encryption key during new Oracle Grid Infrastructure 19c deployment or an upgrade to Oracle Grid Infrastructure 19c to secure the interconnect communication.

E. Database administrators or cluster administrators must provide a valid server certificate and an Oracle Wallet for each node during new Oracle Grid Infrastructure 19c deployment or an upgrade to Oracle Grid Infrastructure 19c to secure the interconnect communication.

정답: C

문제5

B. Grid Infrastructure must be installed on all cluster nodes.

C. Grid Infrastructure must be installed on all cluster nodes where the Database software will be installed.

D. The Clusterware stack must be up on all cluster nodes where the Database software will be installed.

E. ssh user equivalence for the Oracle software owner must be configured on all cluster nodes where the Database software will be installed.

F. The Clusterware stack must be up on all cluster nodes.

정답: B,E

문제6

B. Each leaf node must be connected to storage shared across all leaf nodes.

C. Each leaf node must be connected to storage shared across all cluster nodes.

D. Leaf nodes require direct access to the voting disks.

E. Each hub node must be connected to storage shared across all hub nodes.

F. Hub nodes require direct access to the OCR file.

정답: A,E,F
