문제1

The storage administrator is adding several disks to a pool of ASM disks. The current ASM_DISKSTRING parameter is "/dev/sda*", "/dev/sdb*", "/dev/sd*6". There are several hundred disk partitions currently.
The new disks are /dev/sdf1, /dev/sdg1, /dev/sdh1, and /dev/sdd6.
Which ASM_DISKSTRING parameter would perform the best by searching the fewest number of devices for ASM discovery?

A. ASM_DISRSTRING="/dev/sd*"

B. ASM_DISKSTRING="/dev/sda*", "/dev/sdb*", "/dev/sd*6","/dev/sd*1"

C. ASM_DISKSTRING="/dev/sda*", "/dev/sdb*", "/dev/sd*6","/dev/sd*"

D. ASM_DISKSTRING="/dev/sda*", "/dev/sdb*", "/dev/sd*6", "/dev/sdf1", "/dev/sdg1", "/dev/sdh1"

E. ASM_DISKSTRING=""

문제2

You are managing a three-Instance RAC database. In the AWR report, you notice a gc current block busy wait event on one of the database Instances, in the cluster top timed events section.
What are two possible reasons for this wait event?

A. CPU shortages.

B. Access to blocks was delayed by log writes on remote Instance.

C. Access to blocks was delayed as the blocks were pinned In exclusive mode for updates by some sessions.

D. Frequently used select statements are causing high disk Input/output contention.

문제3

Which two statements are true regarding the Automatic Workload Repository (AWR) In a RAC environment?

A. The Manageability Monitor Processes (MMON) process gathers statistics every hour from every instance and creates an AWR snapshot and stores it In the SGA.

B. The AWR includes time model statistics based on time usage for activities displayed In the VSSYS_TIME_MODEL and VSSESS_TIHE_HODEL views.

C. The MMON process gathers statistics from its' own instance and kicks off statistics collection form other instances every hour from other instances and creates an AWR snapshot which is written to the sysaux tablespace.

D. The AWR is controlled by the statistics_level initialization parameter and it must be set to TYPICAL or BASIC
