Oracle 1Z0-064 Exam Questions

?

01. Database Replay can be used to determine the overall performance change for a variety of situations. Which of the following performance tests is NOT a proper use of Database Replay?

Option a) A change in operating system versions b) A workload applied to a different database version

c) A workload from a single instance applied to RAC database d) A set of SQL statements between database versions

ANSWER d) A set of SQL statements between database versions

02. Which two statements are true about ADDM or RealTime ADDM? (Choose two.)

Option a) ADDM can be run manually by selecting any range of AWR snapshots available within the AWR retention period, provided they do not cover a time period when the instances were restarted. b) ADDM runs in Partial mode to analyze any hung database issues. c) Real-Time ADDM can proactively detect and diagnose transient performance issues that last for a few seconds. d) Real-Time ADDM is automatically invoked by ADDM at the end of every hour.

ANSWER a) ADDM can be run manually by selecting any range of AWR snapshots available within the AWR retention period, provided they do not cover a time period when the instances were restarted. c) Real-Time ADDM can proactively detect and diagnose transient performance issues that last for a few seconds.

03. Every database tuning session has some common steps. Which of the following is not a tuning step?

Option a) Comments b) Literals

c) Variables d) Identifiers e) Delimiters

ANSWER d) Identifiers

04. In which three situations can dynamic statistics be used? (Choose three.)

Option a) when the sampling time is a small fraction of the total time for a query b) when an execution plan is suboptimal because of complex predicates

c) when extended statistics are not available for SQL statements that use complex predicates d) when a query is on a partitioned table with a global index e) when index statistics are missing on a column that is used in SQL statements with highly selective filters

ANSWER a) when the sampling time is a small fraction of the total time for a query b) when an execution plan is suboptimal because of complex predicates c) when extended statistics are not available for SQL statements that use complex predicates

05. Which two statements are true about gathering statistics? (Choose two.)

Option a) If an application has only SQL statements with bind variables, it is better to drop existing histograms, disable creation of histograms, and allow the optimizer to select the best execution plans.

b) If end users query newly inserted data, it is possible to get a suboptimal execution plan even if the automatic statistics gathering job is enabled. c) If concurrent statistics gathering is done by using parallel execution, the Resource Manager should be used for efficient resource management. d) For each session that is accessing a global temporary table, the optimizer uses only the shared statistics.

ANSWER b) If end users query newly inserted data, it is possible to get a suboptimal execution plan even if the automatic statistics gathering job is enabled. c) If concurrent statistics gathering is done by using parallel execution, the Resource Manager should be used for efficient resource management.
