NEW QUESTION # 25
You are concerned about the operating temperature of the database servers in your Exadata Full Rack and want to be alerted if the server exceeds 30C.
What command should use use to generate alerts for such an event?

  • A. dbmcli -e "create threshold ds_temp comparison='>', critical=30" on each database server
  • B. dbmcli -e "set alert ds_temp> 30" on each database server
  • C. dbmcli -e "alert metriccurrent ds_temp where metricValue > 30" on each database server
  • D. dbmcli -e "set threshold ds_temp comparison=' >', critical=30" on each database server

Answer: A

Explanation:
The correct command to generate alerts for an event when the temperature of the database servers in an Exadata Full Rack exceeds 30C is "dbmcli -e "create threshold ds_temp comparison='>', critical=30" on each database server". The dbmcli is the command-line interface for the Oracle Database Management Agent (DMA), which allows you to perform various management tasks on the Exadata servers. This command creates a threshold for the ds_temp metric with a comparison operator of ">" (greater than), and a critical value of 30. The threshold is set on all database servers in the Exadata Full Rack, so when the server temperature exceeds 30C, an alert will be generated.


NEW QUESTION # 26
Which are two valid reasons for executing an X9M-2 Exadata storage server rescue procedure?

  • A. corruption in a normal or high redundancy ASM diskgroup
  • B. accidental loss of all data from all griddisks in a storage server
  • C. corruption in the / (root) filesystem
  • D. the failure of physical disk 1
  • E. the failure of both physical M.2 disks
  • F. moving all disks from one cell to another as part of a chassis-level component failure
  • G. the failure of physical disk 0 and 11

Answer: B,C

Explanation:
Reason B, corruption in the / (root) filesystem, is a valid reason for executing a storage server rescue procedure. If the root filesystem is corrupted, the storage server will no longer be able to boot and will need to be rescued.
Reason F, accidental loss of all data from all griddisks in a storage server, is also a valid reason for executing a storage server rescue procedure. If all data is accidentally lost from the griddisks in a storage server, the server will need to be rescued in order to recover the data.

NEW QUESTION # 29
How do ASM failure groups provide redundancy?

  • A. They ensure that the ASM Flex instances are enabled on a maximum of two database servers or VMs per cluster.
  • B. Failure groups contain all ASM disks in a single storage server preventing mirror copies being written to the same storage server.
  • C. Failure groups are created for each grid disk to ensure mirror copies are written to the same storage server for faster recovery after a physical disk failure.
  • D. Extended Redundancy mirrors data across data centers providing the highest levels of data protection.

Answer: B

Explanation:
According to Oracle's documentation12, ASM failure groups provide redundancy by storing mirror copies of data on different disks or storage servers. When ASM allocates an extent for a normal redundancy file, ASM allocates a primary copy and a secondary copy. ASM chooses the disk on which to store the secondary copy so that it is in a different failure group than the primary copy1. This way, if one disk or storage server fails, ASM can still access the data from another failure group2.
Therefore, the statement that is true about how ASM failure groups provide redundancy is:
Failure groups contain all ASM disks in a single storage server preventing mirror copies being written to the same storage server.

NEW QUESTION # 33
Which two statements are true about the initial storage configuration after the standard (non-virtualized) deployment of a new Exadata Database Machine with High Capacity storage servers?

  • A. There is free space available on flashdisks inside the Exadata storage servers for possible use for storage indexes.
  • B. There is free space available on flashdisks inside the Exadata storage servers to configure Exadata Smart Flash Logs.
  • C. The DATA_<DBM_Name> and RECO_<DBM_NAME> ASM diskgroups are built on with DATA on the outer-most tracks and RECO on the inner-most tracks of the physical disk.
  • D. The sparse_<DBM_NAME> diskgroup is created automatically.
  • E. There is free space available on the hard disks inside the database servers for possible extension of the /uoi file system.

Answer: A,B

Explanation:
According to the Oracle Exadata Database Machine Technical Architecture1, the initial storage configuration after the standard (non-virtualized) deployment of a new Exadata Database Machine with High Capacity storage servers includes two ASM disk groups: DATA_<DBM_Name> and RECO_<DBM_NAME>. These disk groups are built on hard disks and flash disks inside the Exadata Storage Servers1.
The correct statements about this configuration are:
Option D: There is free space available on flashdisks inside the Exadata storage servers for possible use for storage indexes. Storage indexes are a feature of Exadata Storage Software that can improve query performance by avoiding unnecessary I/O operations. Storage indexes use a small amount of flash memory to store metadata about data blocks stored on disk1.
Option E: There is free space available on flashdisks inside the Exadata storage servers to configure Exadata Smart Flash Logs. Exadata Smart Flash Logs are another feature of Exadata Storage Software that can improve database performance by using flash memory as an extension of the database redo log buffer. This can reduce latency and increase throughput for redo log writes1.
