Oracle Exadata Database Machine X8M Implementation Essentials Sample Questions (Q75-Q80):

NEW QUESTION # 75
Which statement is true about the Persistent Memory Commit Accelerator?

  • A. Persistent Memory Commit Accelerator reduces redo log write latency by using Persistent Memory and RDMA before flushing to Flash then disk.
  • B. Persistent Memory Commit Accelerator tracks changes to Persistent Memory Data Accelerator to ensure duplicate blocks are not written to Flash.
  • C. Persistent Memory Commit Accelerator helps to further reduce redo log write latency by using Persistent Memory and Remote Direct Memory Access (RDMA).
  • 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: A

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.
This is according to the Oracle Exadata Database Machine X9M Implementation Essentials Official Text Book and Resources [1][2]. The Persistent Memory Commit Accelerator uses Persistent Memory and Remote Direct Memory Access (RDMA) technology to write redo log data to Flash and disk, resulting in improved latency and higher throughput. Additionally, the Accelerator tracks changes to Persistent Memory Data Accelerator to ensure duplicate blocks are not written to Flash [1], further reducing latency.


NEW QUESTION # 76
How is Exadata Secure RDMA Fabric isolation used in X9M-2 with virtualization enabled?

  • A. With Secure Fabric isolation, each Database VM cluster uses a dedicated network partition and VLAN ID for cluster networking between the database servers in the VM Cluster. This provides security and isolation between multiple tenants or VM clusters.
  • B. With Secure Fabric isolation, each Database VM Cluster uses a dedicated network partition and VLAN ID for Data Guard networking between the primary and disaster recovery Exadata racks. This improves security by isolating data guard traffic onto an encrypted network between data centers.
  • C. With Secure Fabric isolation, each Storage Server runs multiple KVM guests each dedicated to a Database VM cluster using a dedicated network partition and VLAN ID. This provides security and isolation between multiple tenants or VM clusters.
  • D. With Secure Fabric isolation, each Database VM Guest uses a dedicated network partition and VLAN ID for client networking between application servers. This improves security by preventing man in the middle attacks.

Answer: A


NEW QUESTION # 77
Which two sections of the AWR report shows statistics for X9M Persistent Memory Cache?

  • A. PMEM Cache section within Memory Statistics
  • B. PMEM Cache section within Exadata Smart Statistics
  • C. PMEM Pool cache Read Hits in the Cache Sizes portion of the Report Summary
  • D. PMEM Pool Misses in the Exadata Outlier Summary
  • E. cell PMEM cache Read Hits in the Database IOs portion of the Performance Summary

Answer: B,E

Explanation:
Option C shows the number of read hits from PMEM cache on storage servers which indicates how much data was served from PMEM instead of flash or disk1.
Option E shows detailed information about PMEM cache such as size, utilization, hit ratio, read latency and write latency2.


NEW QUESTION # 78
Which of the following is NOT a requirement when validating, receiving, unpacking, and planning access route and space requirements for Exadata Database Machine?

  • A. A conditioned space is required to remove the packaging material to reduce particles before entering the data center.
  • B. 914mm of space required above the rack height is required for maintenance access.
  • C. Oracle Exadata Rack may only be installed on raised floor environments.
  • D. The incline of any access route ramp must be less than or equal to 6 degrees.
  • E. All four leveling and stabilizing feet should be raised and out of the way prior to moving the rack.
  • F. The entire access route to the installation site should be free of raised-pattern flooring that can cause vibration.

Answer: C

Explanation:
Exadata Database Machine is a pre-configured and pre-tuned hardware and software system designed to run Oracle Database, it can be installed on raised floor environments, but also on concrete or tile floors Oracle Exadata Database Machine X9M Implementation Essentials states that Exadata racks are designed to be installed on flat surfaces, not raised floor environments. It is not required to install the rack on raised floor environments. Additionally, the other options listed are all requirements for validating, receiving, unpacking, and planning access route and space requirements for Exadata Database Machine.

NEW QUESTION # 79
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. the failure of physical disk 0 and 11
  • C. the failure of physical disk 1
  • 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. moving all disks from one cell to another as part of a chassis-level component failure

Answer: D,F

Explanation:
The two valid reasons are:
corruption in the / (root) filesystem . According to 1, this is one of the scenarios that requires a storage server rescue procedure , because it prevents the storage server from booting up normally . The rescue procedure will re-image the root filesystem with a fresh copy of the operating system and restore the configuration files from a backup1.
the failure of both physical M.2 disks . According to 2, each Exadata Storage Server X9M-2 has two physical M.2 disks that store the operating system and configuration files for the storage server . If both M.2 disks fail , then the storage server cannot boot up or function properly . The rescue procedure will replace the failed M.2 disks with new ones and re-image them with the operating system and configuration files2.
