View the Exhibit exhibit1 to examine the series of SQL commands. View the Exhibit exhibit2 to examine the plans available in the SQL plan baseline. The baseline in the first row of the Exhibit is created when OPTIMIZER_MODE was set to FIRST_ROWS.Which statement is true if the SQL query in exhibit1 is executed again when the valueof OPTIMIZER_MODE is set to FIRST_ROWS?()
A. The optimizer uses a new plan because none of the plans in the exhibit2 are fixed plans.
B. The optimizer uses the plan in the second row of the exhibit2 because it is an accepted plan.
C. The optimizer uses the plan in the first row of the exhibit2 because it is the latest generated plan.
D. The optimizer uses the plan in the first row of the exhibit2 because OPTIMIZER_MODE was set to FIRST_ROW during its creation.

In which two environments would intra-partition parallelism be used? ()
第5题:
A database administrator wants to design a multi-partition database that can take advantage of both intra-partition parallelism and inter-partition parallelism. Which configuration will allow the use of these types of parallelism while using the least number of hardware components (servers, processors)? ()
第6题:
Examine the parameter for your database instance:You generated the execution plan for the following query in the plan table and noticed that the nested loop join was done. After actual execution of the query, you notice that the hash join was done in the execution plan:Identify the reason why the optimizer chose different execution plans.()
A. The optimizer used a dynamic plan for the query.
B. The optimizer chose different plans because automatic dynamic sampling was enabled.
C. The optimizer used re-optimization cardinality feedback for the query.
D. The optimizer chose different plan because extended statistics were created for the columns used.

第8题:
You perform the following activities during the database upgrade from Oracle Database 10g to Oracle Database 11g:1. Capture plans for a SQL workload into a SQL Tuning Set (STS) before upgrade.2. Load these plans from the STS into the SQL plan baseline immediately after the upgrade.What is the reason for performing these activities? ()
A. to minimize plan regression due to the use of a new optimizer version
B. to completely avoid the use of new plans generated by a new optimizer version
C. to prevent plan capturing when the SQL statement is executed after the database upgrade
D. to keep the plan in the plan history so that it can be used when the older version of the optimizer is used

During Company.com planning session,Company.com presents the details of the current Network design. The network design serves four separate company facilities, each on as separate subnet. As part of a disaster recovery plan, the customer is evaluating the use of HACMP. Specifically, the have reviewed IPAT via IP aliasing and are questioning the number of IP subnets required. Given the customer’s current configuration,what is the recommended minimum number of IP subnets that would be required?()
