Your system administrator reports an amber, non-blinking light on one of your Exadata storage disks. You immediately execute the 'LIST PHYSICALDISK WHERE diskType=HardDisk AND status=failed DETAIL' command on the Exadata storage system and the specified disk is indeed reported as failed. Platinum Support has not been enabled for this system. Enterprise Manager Cloud Control is monitoring the system.
What is the next step that you should perform before you do anything else?
ACall Oracle Support and make an appointment so that the drive can be replaced.
BDownload and run the latest exadiag tool.
CWait for the email of the failure that Exadata or Enterprise Manager will send.
DWait for a blue light to appear on the disk.
EAsk the system administrator to replace the broken disk with a spare.

Which two statements are true about enabling write-back flash cache? (Choose two.)
ABefore write-back flash cache is enabled, you need to drop the Flash Cache first.
BWrite-back Flash Cache cannot be used on Extreme Flash Storage Servers.
CWhen enabling write-back flash cache in a rolling manner, DBCLI should be used to inactivate the grid disks on all cells first.
DWhen enabling write-back flash cache in a non-rolling manner, you need to drop the Persistent Memory Commit Accelerator (PMEMLog) first.
EWrite-back flash cache is on by default for High Capacity Storage Servers in High Redundancy configurations.
You are updating your Exadata X9M-2 Elastic Database Machine with 6 database servers and 12 High Capacity Storage Servers. You will be using patchmgr to apply updates across the entire machine while still maintaining database availability.
Assuming you are driving patchmgr from an external server, which statement is true about the execution phase?
Apatchmgr will apply patches in component groups consisting of 1 database server and 2 storage servers to minimize disruption.
Bpatchmgr must be invoked with the --rolling argument. Each component type must be upgraded independently of the other.
Cpatchmgr cannot apply updates in a rolling manner, you must manually apply patches with the dbnodeudpate and cellupdate tools if high availability is required.
Dpatchmgr must be invoked with the --rolling argument with all database and storage servers listed in a single input file.
An Exadata storage server physical disk on an X9M-2 high-capacity full rack entered the predictive failure state.
Which two steps must you perform to replace this failed physical disk? (Choose two.)
ACreate a new celldisk and new griddisks on the replaced physical disk.
BReplace the failed physical disk.
CIdentify the griddisks located on the failed physical disk and drop them from the associated ASM diskgroups.
DAdd the griddisks back into the ASM diskgroup they used to be a member of.
ERebalance the data on the effected griddisks before performing a manual drop command.
FVerify that the griddisks located on the physical disk have been successfully dropped from the associated ASM diskgroups.
Which statement is TRUE about the Persistent Memory Commit Accelerator?
APersistent Memory Commit Accelerator contains logging information from all tiers of the software stack for rapid triage and diagnostics.
BPersistent Memory Commit Accelerator reduces redo log write latency by using Persistent Memory and RDMA before flushing to Flash then disk.
CPersistent Memory Commit Accelerator tracks changes to Persistent Memory Data Accelerator to ensure duplicate blocks are not written to Flash.
DPersistent Memory Commit Accelerator copies redo log data from disk for faster redo apply on Data Guard Standby Databases.
EPersistent Memory Commit Accelerator allows the database to issue one-way RDMA writes to PMEM, FLASH, and Disks concurrently, thereby reducing redo fog write latency.
