B. Replication is controlled by using sqlplus while you are logged in as SYSASM.
C. Replication is controlled by using the acfsutil command-line tool.
D. Replication of ACFS filesystems for non-database files on Exadata is not supported.
E. Replication is controlled by using the exacli command-line tool.
Your customer is implementing a storage consolidation strategy on their existing Exadata.
Which step represents the Oracle recommended action that the customer should take in their approach?
A. Do not use IORM because it will interfere with the shared database functionality on Exadata.
B. Use ASM to create separate diskgroups for each database instance that is running on Exadata.
C. Use IORM to distribute disk bandwidth among the databases.
D. Set up Oracle Grid Infrastructure to use multiple clusters per hardware pool.
E. Set up a resource consumer group within each database instance and manage it individually.
Your government customer has purchased a full rack of Exadata. The customer has two departments that would like to share the Exadata Database Machine but the concern is that department A will be able to see data from department B.
Which architecture would you suggest to solve this deployment issue?
A. Split the configuration by using Oracle Nimbula's cloud software so that four database servers and seven cells can be used by department A and the rest can be used by department B.
B. Split the configuration and use ASM-Scoped Security so that four database servers and seven cells can be used by department A and the rest can be used by department B.
C. Set up instance caging to ensure that department A has access only to four database servers and seven cells and department B has access to the rest.
D. Define the split by setting up database services that are specific to department A and department B.
Which three mandatory tasks must be performed when configuring the Auto Service Request (ASR) Manager? (Choose three.)
A. verifying the ASR configuration
B. registering the ASR Manager
C. activating a node on the ASR Manager
D. installing the ASR software on each database server
E. setting up ASR SNMP traps in Enterprise Manager
Your customer wants to load source information into a database. The source files are generated on a remote HP-UX system and need to be written to the Exadata system. The ideal solution would be to use a remote file system where an ACFS file system is exported to the HP-UX system.
Which three options are supported using ACFS on Exadata 12.1.0.2 and later?
A. SAMBA
B. NFS
C. HANFS
D. DBFS
E. ACFS is not supported on Exadata
Which three options describe the flash memory capabilities of the Exadata X6-2 database and storage servers? (Choose three.)
A. no flash storage on the database server
B. 4 x 3.2 TB NVMe flash cards on the HC storage server
C. 8 x 3.2 TB NVMe flash cards on the EF storage server
D. 4 x 3.2 TB NVMe flash cards on the database server
E. 8 x 3.2 TB NVMe flash cards on the HC storage server
Which two statements are true about CellCLI? (Choose two.)
A. CellCLI can be used to back up the Exadata storage cells or make a bootable disk to restore the cell.
B. With a simple CellCLl command, you can synchronize changes to all the storage cells in the Exadata realm.
C. Using CellCLI, you can stop and start the ASM instances that are using the grid disks on the Exadata storage cell.
D. Using a CellCLI command, you can change the SNMP subscribers or add multiple SNMP subscribers.
E. Using a CellCLI command, you can see whether grid disks are being used by ASM or not.
Storage indexes are unique to Exadata Database Machine and their primary goal is to reduce the amount of I/O required to service I/O requests for Exadata Smart Scan. Put the following steps in order:
1.
The Exadata cell services software conducts I/O requests on 1 MB storage regions.
2.
cellsrv checks the high and low values, and determines that the storage region does not contain any values that meet the predicate.
3.
The database is started.
4.
Physical I/O to the region is bypassed if the query selection falls outside the high/low storage index storage.
5.
A query is issued against the MYOBJ_CTRL table that has a predicate OBJECT_ID=1500.
6.
A subsequent query is issued against the MYOBJ_CTRL table that has a predicate OBJECT_ID=2234.
7.
The MYOBJ_STATE’S region index is populated with high and low values for the OBJECT_ID column during the l/O request.
A. 3, 5, 1, 7, 6, 2 and 4
B. 3, 7, 1, 5, 6, 2, and 4
C. 3, 7, 5, 2, 1, 6, and 4
D. 3. 6, 1, 7, 2, 5, and 4
E. 3, 5, 2, 1, 6, 7, and 4
Which two statements are true about the two types of Exadata storage servers, the HC storage server and the EF storage server?
A. The EF storage servers contain 8 X 3.2TB PCIe flash cards.
B. The HC storage servers contain 12 X 8TB hard disks and 4 X 3.2TB PCI flash cards.
C. The HC storage server is an all disk storage server with no flash containing 12 X 8TB hard disk.
D. The EF storage server contains 8 X 3.2TB PCI flash card and can be upgraded with 4 more a total of
12.
E. The EF storage server contain 8 X 3.2TB PCI flash cards and 4 X 8TB disk drives.
Your customer would like to install security software on all systems that are hosted out of their datacenter. Which statement correctly identifies Oracle guide line on where security software can be installed on Exadata?
A. The security software can be installed on the database server or a storage cells as long as the software is certified for Oracle enterprise Linux.
B. The security software can be installed on the database server or storage cells as required.
C. The security software can be installed on database server but not on the storage cell.
D. The security software can be installed on database server but not on the storage cells unless the software is explicitly certified for Oracle enterprise Linux.
