Which three statements are true about the CELLCLI command?
- A. It can execute commands on multiple storage servers in parallel.
- B. It can be executed on storage servers.
- C. It has command-line history.
- D. It can be executed using the DCLI utility.
- E. It requires root privileges to create CELLDISKS and GRIDDISKS.
Answer: B,C,D
Explanation:
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.

NEW QUESTION 39
Which are two valid reasons for executing an X9M-2 Exadata storage server rescue procedure?
- A. the failure of physical disk 1
- B. corruption in a normal or high redundancy ASM diskgroup
- C. moving all disks from one cell to another as part of a chassis-level component failure
- D. the failure of both physical M.2 disks
- E. accidental loss of all data from all griddisks in a storage server
- F. corruption in the / (root) filesystem
- G. the failure of physical disk 0 and 11

Explanation:
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.
