Actual Oracle 1Z0-078 Exam Questions

Question 1

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?

ASecurity 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.

BSecurity 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.

CSecurity 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.

DDatabase 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.

EDatabase 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.

Correct answer: A

Question 2

Which two statements are true about resources defined by an administrator and registered with Oracle 19c Clusterware for high availability? (Choose two.)

AAn administrator-managed resource can be started manually using srvct1.

BA policy-managed resource can be started manually using crsct1.

CAn administrator-managed resource can be started manually using crsct1.

DThe action script is automatically set when using a policy-managed resource.

EA policy-managed resource can be started manually using srvct1.

FResource dependencies are automatically set when using a policy-managed resource.

Correct answer: B, C

Question 3

Which three statements are true about ASM Cloud File System (ACFS) auditing? (Choose three.)

Aacfsutil audit read marks audit files to indicate that it is safe to purge them.

Bacfsutil audit init must be run by a system administrator.

Cacfsutil audit purge can be run by an audit manager.

DAudit information gathered by each cluster node can be consolidated into the unified ACFS audit trail.

Eacfsutil audit archive must be used to archive audit files that are larger than 10 MB.

Correct answer: B, C, D

Question 4

Which two statements are true about node listeners in a Grid Infrastructure Cluster using ASM? (Choose two.)

AThey listen only for database instances on the same node.

BThey listen on behalf of any ASM instance and all database instances on the same node.

CThey listen only for the ASM instance on the same node.

DThere can be only one node listener per node.

EThey run from the Grid Infrastructure home by default.

Correct answer: B, E

Question 5

Which two methods exist for enabling the collection of additional resource debugging information for specific resources controlled by Oracle 19c Clusterware? (Choose two.)

AUse the crsct1 set trace res 'resource_name=debugging_level' command.

BUse the crsct1 set log res 'resource_name=debugging_level2' command.

CSet the environment variable _USR_ORA_DEBUG=1 and then stop and restart the resource that requires resource debugging data to be collected.

DUse the cluvfy comp command for the specific resource within a component.

Correct answer: A, C
