第8题：

The system administrator notices that there is an I/O bottleneck on one of three disks in datavg volume group. This problem disk contains the JFS log， loglv00 and one filesystem， /mydatabase.  There are no other logical volumes on this disk.  Which of the following options would be the best solution？（）

• A、 Increase the size of the JFS log logical volume so more transacations can be written to this log.
• B、 Create a second， additional JFS log and have the /mydatabase logical volume point to both JFS logs.
• C、 Migrate the JFS log device to another physical disk in the same volume group.
• D、 Only one JFS log device for each volume group can be used.  Use the migratepv command to move the JFS log device to an empty disk in another volume group.

第10题：

What is the objective of the superstrict option that can be used when creating mirrors?（）

• A、Allows the mirror partitions to spread across a maximum number of disks.
• B、Allows the copy of a partition to be on the same physical volume as the mirrored partition.
• C、Prevents partitions allocated to one logical volume mirror from sharing a physical volume with partitions from another logical volume mirror.
• D、Forces copies of logical partitions to be housed on different physical volumes, while allowing a single physical volume to be shared by logical volume mirrors.
