Oracle Exadata Database Machine X8M Implementation Essentials Sample Questions (Q32-Q37):

NEW QUESTION # 32
What is the minimum Exadata System Software version required for Exadata X9M?

  • A. 19.3.0.0.0
  • B. 19.2.1 0.0
  • C. 21.3.0.0.0
  • D. 18.1.3.0.0
  • E. 21.2.0.0.0
  • F. 20.1.1.0.0

Answer: E

Explanation:
The minimum Exadata System Software version required to support Oracle Exadata X9M is 21.2.0.0.0. This version introduced various enhancements and capabilities tailored for the X9M series, including optimizations for the RoCE network fabric and support for new hardware components .


NEW QUESTION # 33
Which are two valid reasons for executing an X9M-2 Exadata storage server rescue procedure?

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

Answer: A,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 # 34
Which two statements are true about enabling write-back flash cache?

  • A. Write-back Flash Cache cannot be used on Extreme Flash Storage Servers.
  • B. Before write-back flash cache is enabled, you need to drop the Flash Cache first.
  • C. Write-back flash cache is on by default for High Capacity Storage Servers in High Redundancy configurations.
  • D. When enabling write-back flash cache in a non-rolling manner, you need to drop the Persistent Memory Commit Accelerator (PMEMLog) first.
  • E. When enabling write-back flash cache in a rolling manner, DBCLI should be used to inactivate the grid disks on all cells first.

Answer: B,C

Explanation:
According to the Oracle documentation1, two statements that are true about enabling write-back flash cache are:
Write-back flash cache is on by default for High Capacity Storage Servers in High Redundancy configurations (A). This is because write-back flash cache provides better performance and reliability for data file writes than write-through flash cache.
Before write-back flash cache is enabled, you need to drop the Flash Cache first (D). This is because changing the flash cache mode requires recreating the flash cache with a different configuration.


NEW QUESTION # 35
Assume that the RDBMS and ASM instances are up and you are enabling write-back flash cache in one cell server at a time.
Which step(s) should you perform before executing the following command you your Exadata X9M-8 Database Machine, which will set the cell flash cache mode to write-back?
#cellcli -e alter cell flashCacheMode=WriteBack

  • A. Shut down the CELL5RV service on the cell.
  • B. Disable the storage indexes on the cell.
  • C. Inactivate all the physical disks on the cell.
  • D. Inactivate the grid disks on the cell.
  • E. Drop the existing flash cache on the cell.
  • F. Create a new flash cache on the cell.

Answer: E,F

Explanation:
To enable the write-back flash cache on an Exadata X9M-8 storage cell, the existing flash cache must be removed before transitioning to a new mode. This is because the flash cache configuration-whether set to write-through or write-back-requires a re-initialization of the flash storage to apply the new caching behavior. The steps are as follows:
Drop the Existing Flash Cache: Before altering the cache mode, any existing flash cache on the cell must be dropped. This clears the existing configuration and allows the system to reallocate flash resources under the new mode. The command for this is:
# cellcli -e "drop flashcache"
Create a New Flash Cache in Write-Back Mode: After dropping the existing flash cache, you can create a new flash cache with write-back mode enabled. This step ensures that the flash cache is configured correctly to handle write operations before they reach disk, thus accelerating write-heavy workloads. The relevant command to set write-back mode is:
# cellcli -e "create flashcache all"
This process will reset the flash cache with the write-back mode enabled, thereby caching both read and write operations effectively.


NEW QUESTION # 36
Which statement is true about the Persistent Memory Commit Accelerator?

  • A. Persistent Memory Commit Accelerator tracks changes to Persistent Memory Data Accelerator to ensure duplicate blocks are not written to Flash.
  • B. Persistent Memory Commit Accelerator helps to further reduce redo log write latency by using Persistent Memory and Remote Direct Memory Access (RDMA).
  • C. Persistent Memory Commit Accelerator reduces redo log write latency by using Persistent Memory and RDMA before flushing to Flash then disk.
  • D. Persistent Memory Commit Accelerator copies redo log data from disk for faster redo apply on Data Guard Standby Databases.
  • E. Persistent Memory Commit Accelerator contains logging information from all tiers of the software stack for rapid triage and diagnostics.

Answer: C

Explanation:
Persistent Memory Commit Accelerator reduces redo log write latency by using Persistent Memory and RDMA before flushing to Flash then disk. This helps to further reduce redo log write latency by utilizing the speed and low latency of Persistent Memory, along with the Remote Direct Memory Access (RDMA) protocol, to commit changes to disk faster. This allows the system to quickly commit changes to disk, resulting in improved performance and reduced latency.
