質問 1：
An Exadata storage server physical disk on an X5 high-capacity full rack entered the predictive failure state.
Identify the two steps that you must perform to replace this failed physical disk.
A. Add the griddisks back into the ASM diskgroup they used to be a member of.
B. Replace the failed physical disk.
C. Create a new celldisk and new griddisks on the replaced physical disk.
D. Verify that the griddisks located on the physical disk have been successfully dropped from the associated ASM diskgroups.
E. Identify the griddisks located on the failed physical disk and drop them from the associated ASM diskgroups.

質問 2：
Which two statements are true about backup performance when using Recovery Manager (RMAN) on an X5 Database Machine?
A. Backups are fast, because all data blocks are read from the Exadata Smart Flash Cache.
B. Backups are fast because the Infiniband network is faster than fiber channel storage, so RMAN read I/O operations are faster than in traditional storage networks.
C. Backups are fast, because data blocks are read from the Database Flash Cache.
D. Backups are fast, because physical I/Os operations are reduced by the use of the Storage Index by cellsrv.
E. For incremental backups using Block Change Tracking, cellsrv filters blocks and returns only those that have changed since the last backup.

質問 3：
Your X6 Exadata Database Machine is running Oracle Database 12c, and has a large database with some very large tables supporting OLTP workloads.
High-volume insert applications and high-volume update workloads access the same tables.
You wish to compress these tables without causing unacceptable performance overheads to the OLTP workload.
Which three are true regarding this requirement?
A. Using row store compress advanced will compress the data less than if using column store compress for query low.
B. Compression is performed on database servers when using row store compress advanced in an Exadata environment.
C. Compression is performed on Exadata Storage Servers when using row store compress advanced in an Exadata environment.
D. Using row store compress advanced will compress the data more than if using column store compress for archive low.
E. The compression method column store compress for archive high is the worst fit for this requirement.

質問 4：
Which two statements are true about Database Server Metrics and Alerts on an X5 Database Machine?
A. Database Server Threshold Alerts may be forwarded by the MS process as SNMP traps.
B. Database Server Metrics are collected my MMON.
C. Database Server Metrics are collected by the RS process.
D. Database Server hardware sensor alerts are detected by the MS process on the database server.
E. Database Server Metrics are collected by the MS process and stored in an internal disk-based repository.
正解：A,E

質問 5：
Which three statements are true regarding the configuration of Auto Service Request (ASR) on an X5 Database Machine?
A. Oracle Solaris must be used on the server where ASR Manager is installed.
B. ASR Manager must be installed on one of the database servers.
C. ASR Manager may be installed on any type of server running Oracle Solaris.
D. Oracle Linux must be used on the server where ASR Manager is installed.
E. HTTPS connectivity must be enabled from the ASR Manager host to the Internet.
F. SMTP must be enabled on at least one database server.
G. ASR Manager may be installed on any type of server running Oracle Linux.

質問 6：
You are patching your Exadata X6 Database Machine by applying a new image to the Storage Servers in a rolling fashion.
Your ASM environment on the Database Machine has five diskgroups stored on an unpartitioned Exadata storage grid, with redundancy settings as shown:
1. DATA_DBM1 - Normal Redundancy
2. RECO_DBM1 - Normal Redundancy
3. DBFS_DG - Normal Redundancy
4. DATA2_DBM1 - High Redundancy
5. DATA3_DBM1 High Redundancy
Which two diskgroups will not suffer from any data loss throughout the patching process even if there is a single disk failure on one of the cells
A. RECO_DBM1
B. DBFS_DG
C. DATA_DBM1
D. DATA3_DBM1
E. DATA2_DBM1

質問 7：
Identify three facilities that can use X5 Extreme Flash Exadata Storage Server flashdisk space.
A. Database Smart Flash Cache
B. cell boot flash image
C. Exadata Smart Flash Cache
D. Cell System Area
E. Exadata Smart Flash Log
正解：B,C,E

質問 8：
Which two statements are true about RMAN incremental level-1 backups for a database running on an X5 Database Machine?
A. cellsrv returns all blocks that have been or might have been changed since the last backup, and RMAN filters the blocks that do not require backup.
B. cellsrv filters blocks and returns only those that have changed since the last backup, for databases in archivelogmode.
C. Block Change Tracking (BCT) is not needed for databases in an X5 Database Machine, because change tracking is done by cellsrv.
D. cellsrv filters blocks and returns only those that have changed since the last backup, for databases in noarchivelogmode.
E. Block Change tracking (BCT) is not needed for databases in an X5 Database Machine, because ASM automatically does block change tracking when diskgroups are built from griddisks.
