Question #2

Your customer wants you to partition the database and storage grids in his X3-2 fiull rack, creating database clusters and two storage grids.
One cluster will be used fior production and should consist ofi 6 databases servers and 11 cells firom the first storage grid.
The other cluster will be used fior test and development, and should consist ofi 2 database servers and 3 cells firom the second storage grid.
The storage must be partitioned so that the cells are visible only to the appropriate database servers based on the description above.
What must be done to achieve this?

A. Edit the CELLIP.ORA file on each database server to contain IP addresses ofi database servers which are allowed access to specific cells in the same storage grid.

B. Edit the CELLINIT.ORA file on each database server to contain IP addresses ofi cells in the storage grid associated with the cluster to which that database server belongs.

C. Configure Exadata realms using Oracle ASM scoped security mode.

D. Edit the CELLIP.ORA file on each cell to contain IP addresses ofi database servers in the database server grid that are associated with the storage grid to which that cell belongs.

E. Edit the CELLIP.ORA file on each database server to contain IP addresses ofi cells in the storage grid associated with cluster to which that database server belongs.

F. Configure Exadata realms using Database scoped security mode.

A. A query rewrite may occur to a container table stored Exadata, and it will always benefit firom Smart Scan.

B. Some joins can be offloaded to the storage servers.

C. All joins can be offloaded to the storage servers.

D. a query rewrite may occur to a container table stored in Exadata but will never benefit From Smart scan.

E. It is possible to offload single row fiunctions to the storage servers.

Exadata Database Machine on the InfiniBand network so that the cells on the expansion rack are added to the storage
grid?
