Oracle Database 10g R2: Administering RAC 認定 1Z0-048 試験問題:

1. View the Exhibit.
You are required to support your Oracle RAC configuration using ASM and RAID technology. You plan to discuss the storage configuration with the storage technology team. They have proposed a configuration as shown in the exhibit with a separate set of LUNs for the data disk group and the flash recovery area disk group and a 500 KB stripe size in line with other non-Oracle LUNs. The Data disk group has four250G LUNs and the FRA disk group has four500G LUNS, both of which are mirrored.

A) I/O to the flash recovery area disk group for backups may cause performance issues when full table scans are occurring during batch workloads.
B) The LUNs are not aligned with ASM Allocation Units, which may lead to I/O bottlenecks.
C) Retention policies that require backups to be kept for long time periods may cause wasted space due to large allocation units.
D) Index Range Scans would cause I/O to many different physical disks.

2. In a RAC environment, you see a steep increase for enq:HW- contention and gc current grant wait events. What would you do to fix this issue?

A) Increase the cache size of sequences.
B) Reduce the number of updates causing locks on tables accessed by multiple instances.
C) Use larger uniform extent sizes for objects.
D) Reduce the time of transactions by committing more often.

3. When do you get the first notification after you execute the following command on instance
RDBA1?
execDBMS_SERVER_ALERT.SET_THRESHOLD(-
METRICSJD => dbms_server_alert.elapsed_time_per_call,
WARNINGJDPERATOR => dbms_server_alert.operator_ge,
WARNING_VALUE => 500000',
CRITICAL_OPERATOR => dbms_server_alert.operator_ge,
CRITICAL_VALUE => 750000',
OBSERVATION_PERIOD => 15,
CONSECUTIVEJDCCURRENCES => 3,
INSTANCE_NAME => 'RDBA1',
OBJECT_TYPE => dbms_server_alert.object_type_service,
OBJECT_NAME =>'ERP");

A) when the average elapsed time per call for the ERP service over a 45-minute period exceeds
0.75 seconds
B) when the average elapsed time per call for the ERP service over a 15-minute period exceeds
0.5 seconds three consecutive times
C) when the average elapsed time per call for the ERP service over a 15-minute period exceeds
0.75 seconds three consecutive times
D) when the average elapsed time per call for the ERP service over a 45-minute period exceeds
0.5 seconds

4. According to the Maximum Availability Architecture, which case is best?

A) Run two identical sites with a primary RAC database on the first site, and only a RAC logical standby database on the second site.
B) Run two identical sites with a primary RAC database on the first site, and only a RAC physical standby database on the second site.
C) Run two identical sites with a primary RAC database on the first site, and RAC physical and logical standby databases on the second site.
D) Run two identical sites with a primary RAC database on the first site, and non-RAC physical and logical standby databases on the second site.

5. Several steps must be followed to successfully add a new node to your cluster database. Assuming that a UNIX platform is used, which of the three steps below are correct? (Choose three.)

A) Add the RAC software to the new node using addnode.sh from ORA_CRS_HOM
B) Configure the OS and hardware for the new node.
C) Reconfigure listeners for the new node with netca.
D) Add instances using OUI.
E) Add the node to the cluster using the addnode.sh script run from ORA_CRS_HOME.
