Which two statements are true about CellCLI?

Which two statements are true about CellCLI?

A.
Using a CellCLI command, you can change the SNMP subscribers or add multiple SNMP
subscribers.

B.
Using CellCLI, you can stop and start the ASM instances that are using the grid disks on the
Exadata storage cell.

C.
With a simple CellCLI command, you can synchronize changes to all the storage cells in the
Exadata realm.

D.
Using a CellCLI command, you can see whether grid disks are being used by ASM or not.

E.
You cannot use CellCLI to gather the serial numbers of physical disks.

Explanation:
B:
* Making a grid disk inactive effectively offlines its associated ASM disk.
CellCLI> alter griddisk PRORECO_CD_11_cell01 inactive
GridDisk PRORECO_CD_11_cell01 successfully altered
* The command will wait until the ASM disk becomes offline. If you want the prompt to come back
immediately without waiting, you can use nowait clause.
CellCLI> alter griddisk PRORECO_CD_11_cell01 inactive nowait
You can make it active again:
CellCLI> alter griddisk PRORECO_CD_11_cell01 active
GridDisk PRORECO_CD_11_cell01 successfully altered
Incorrect:
not E: CellCLI> list physicaldisk detail
output include:
physicalSerial: XXXXXX
