質問 3：
Identify the root cause of Enqueue: CF - Contention inthis scenario.

A. Root cause is blocked LGWR due to SCAN_LISTENERS(s) droppingclient connections during DoS event
B. Root causeis a blocked LGWR due to LGWR waits for enqueue:CF - contention, which may be held by another background process.Background process may hold a CF enqueue whileupdating the control file
C. Root causeis blocked LGWR due to LGWR waits LGWR waits ENQUEUE:CF contentionisasymptom of the db file scattered reads and excessive ITL waits
D. Root causeis a stalled LGWR due to LGWR waits Enqueue:CF contention is caused by the db filesequential reads
正解：B

質問 4：
Which statementaccurately describes the benefit of the policy-managed database feature with OracleRAC12cR1?
A. Itprotects against cascade failures due to network usage. It migratesworkload isolation to specific pools. Less important workloads shut down immediately.
B. It protects against cascade failures due to load. It ensures that workload isolation is balanced between pools. Less important workloads start transactionally
C. It protects against cascade failures due to load.It ensures workloads are not isolated between pools.Less important workloads shut downtransactionally.
D. Itprotects against cascade failures due to load.It ensures workload isolation between pools.Less important workloads shut down transactionally
E. It protects against cascade failures due to load.It ensures workload isolation between pools. Less important workloads shut down and start uniformly.
正解：D

質問 5：
Which statement best describes the interaction between an Oracle ASM instance and the Oracle Database?
A. An Oracle Database must use Oracle ASM in a high availability configuration.
B. Oracle ASM provides an access path between a database instance and storage.
C. A database instance uses an extent map provided by Oracle ASM to access data files
D. Oracle ASM provides storage services only and does not interact with the database.
正解：C

質問 6：
If you upgrade to ASM 12cR1 and implement Flex ASM, do you need to upgrade all the databases to 12cR1?
A. No.You cannot upgrade your database instance to 12cR1
B. No.You can run in a mixed 11.2 database instance and a 12cR1 database instance, but the 11.2 instance willfail if the local Flex ASM instanceis moved to another server
C. No.You can run in a mixed 11.2 database instance and a 12cR1 database instance.The
11.2 instance will use the Flex ASM instance of the other server.
D. Yes.Allthe databases need to be upgraded to 12cR1
正解：B
