1z0-070 Free Practice Test

You plan to partition the database and storage grids in an X5-2 full rack, creating two clusters and two storage grids without using virtualization.
One cluster will be used for production and should consist of six database servers and nine storage servers.
The other cluster will be used for test and development, and should consist of two database servers and five storage servers.
The storage must be partitioned so that the storage servers are visible only to the appropriate database servers that are meant to access them.
What must be done to achieve this?

1. A. Configure Exadata realms using Oracle ASM-scoped security mode.
2. B. Configure Exadata realms using Database –scoped security mode.
3. C. Edit the CELLI
4. D. ORA file on each database server to contain IP addresses of storage servers in the storage grid associated with the cluster to which that database server belongs.
5. E. Edit the CELLINI
6. F. ORA file on each database server to contain IP addresses of storage servers in the storage grid associated with the cluster to which that database server belongs.
7. G. Edit the CELLI
8. H. ORA file on each database server to contain IP addresses of database servers which are allowed access to specific storage servers in the same storage grid.
9. I. Edit the CELLI
10. J. ORA file on each storage server on contain IP addresses of database servers in the database server grid that are associated with the storage grid to which that storage server belongs.

Correct Answer: C
The cellinit.ora file is host-specific, and contains all database IP addresses that connect to the storage network used by Oracle Exadata Storage Servers. This file must exist for each
database that connect to Oracle Exadata Storage Servers.
The cellinit.ora file contains the database IP addresses. The cellip.ora file contains the storage cell IP addresses. Both files are located on the database server host.

Identify two valid reasons for executing an X5 Exadata storage server rescue procedure.

1. A. Accidental loss of all data from all griddisks in a storage server
2. B. Corruption in the /(root) filesystem
3. C. Corruption in a normal or high redundancy ASM diskgroup
4. D. The failure of both physical disks 0 and 1
5. E. Only the failure of physical disk 1
6. F. Only the failure of physical disk 0

Correct Answer: BD
The rescue procedure is necessary when system disks fail, the operating system has a corrupt file system, or there was damage to the boot area. If only one system disk fails, then use CellCLI commands to recover. In the rare event that both system disks fail simultaneously, you must use the Exadata Storage Server rescue functionality provided on the Oracle Exadata Storage Server Software CELLBOOT USB flash drive.
