NEW QUESTION # 36
Which two Exadata security features would you configure to control which databases can access which griddisks, when multiple databases share space on your storage servers in an unpartitioned storage grid?
- A. File permissions on the griddisks in each storage server
- B. Exadata storage realms using database-scoped security mode
- C. Exadata storage realms using ASM-scoped security mode
- D. File permissions on the griddisks in each database server
- E. Using EXADCLI instead of CELLCLI to create the griddisks
Answer: B,C
Explanation:
Exadata storage realms using ASM-scoped security mode allows you to control which database can access which griddisks by creating realms at the ASM level, thereby allowing you to limit the access of each database to the griddisks that it needs to access. This is covered in section 3.15.2 of the Oracle Exadata Database Machine X9M Implementation Essentials Official Text Book and Resources [1].

NEW QUESTION # 41
How do ASM failure groups provide redundancy?
- A. 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.
- B. Extended Redundancy mirrors data across data centers providing the highest levels of data protection.
- C. Failure groups contain all ASM disks in a single storage server preventing mirror copies being written to the same storage server.
- D. They ensure that the ASM Flex instances are enabled on a maximum of two database servers or VMs per cluster.
Answer: C
Explanation:
In an Automatic Storage Management (ASM) environment, failure groups are used to provide redundancy for the storage disks. Failure groups are used to group together a set of disks and ensure that no two copies of the same data are stored on the same physical disk or storage server. This way, if a disk or storage server fails, the data can still be accessed from the other copy.
For example, if the disks in a failure group are mirrored, one copy of the data is stored on one set of disks, and the other copy is stored on another set of disks. This way, if a disk or storage server fails, the data can still be accessed from the other copy.
ASM failure groups also provide the option to spread the data across different storage servers, this way, even if a storage server fails, data can still be accessed from the other storage servers in the group. This will improve the availability of the data.
NEW QUESTION # 42
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 reduces redo log write latency by using Persistent Memory and RDMA before flushing to Flash then disk.
- 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: B
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.

- C. 6, 1, 2, 7, 5, 8
- D. 6, 2, 1, 8, 4, 5
Answer: D
Explanation:
The steps and the order in which they should be executed to create an ACFS Filesystem for use as a staging area for data loads are:
asmcrad volcreate -G data -s 1024G acfs_dataload_vol : This command creates a new volume in the data diskgroup, with a size of 1024 GB, and named acfs_dataload_vol.
asmcmd vol info -G data acfs_dataload_vol | grep Device: This command will show the device name of the newly created volume
/usr/sbin/mkfs -t acfs /dev/asm/ac:fs_dataload_vol-123: This command creates a new ACFS filesystem on the volume created in step 1 sudo /u01/app/19.0.0.0/grid/bin/srvctl start filesystem -device /dev/asn/acfs_dataload_vol-123: This command starts the filesystem created in step 3 sudo chovn -R oracle:dba /mnt/acfs_dataload_vol: This command changes the ownership of the /mnt/acfs_dataload_vol to the oracle:dba user.
/sbin/acfsutil snap create -v data_load /mnt/acfs_dataload_vol: This command creates a snapshot of the filesystem to be used as a staging area.
acfsutil size +2S0G -d /dev/asm/acfs_dataload_vol-123 /mnt/acfs_dataload_vol/ : This command increases the size of the filesystem by 2GB

NEW QUESTION # 46
You are adding a disk expansion kit to a running Exadata X8M Database Machine's Database Servers, and have a filesystem layout that includes:
After running the following commands, which command needs to be run to add 20G of space to the filesystem mounted on /u01?
- A. # lvextend -L +20G -verbose /dev/mapper/VGExaDb-LVDbOral
- B. # lvextend -L +20G -verbose /dev/VGExaDb/LVDbOral
- C. # xfs_growfs /uOl +20G
- D. # resize2fs +20G /dev/VGExaDb/LVDbOral
Answer: A
Explanation:
After running the commands above, the filesystem mounted on /u01 is on the logical volume /dev/mapper/VGExaDb-LVDbOral. So, to add 20G of space to the filesystem mounted on /u01, the command that needs to be run is:
lvextend -L +20G --verbose /dev/mapper/VGExaDb-LVDbOral
This command will extend the logical volume /dev/mapper/VGExaDb-LVDbOral by 20 GB of space. It is important to note that the option --verbose is used to display the progress of the operation.

NEW QUESTION # 50
How do ASM failure groups provide redundancy?
- A. 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.
- B. Extended Redundancy mirrors data across data centers providing the highest levels of data protection.
- C. Failure groups contain all ASM disks in a single storage server preventing mirror copies being written to the same storage server.
- D. They ensure that the ASM Flex instances are enabled on a maximum of two database servers or VMs per cluster.
Answer: C
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 # 51
