Show Answer

Correct Answer: B, D, E

The CellCLI utility supports command-line history.

Each Exadata Storage cell can be monitored, configured, and maintained using the cellcli command line interface.

The dcli utility facilitates centralized management across an Oracle Exadata Storage Server Software realm by automating the execution of CellCLI commands on a set of cells and returning the output to the centralized management location where the dcli utility was run.

Question No. 5

Which are two valid reasons for executing an X9M-2 Exadata storage server rescue procedure?

Athe failure of physical disk 1

Bcorruption in the / (root) filesystem

Cthe failure of both physical M.2 disks

Dthe failure of physical disk 0 and 11

Emoving all disks from one cell to another as part of a chassis-level component failure

Faccidental loss of all data from all griddisks in a storage server

Gcorruption in a normal or high redundancy ASM diskgroup

Show Answer

Correct Answer: B, D

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.
