Which new key architectural element introduced in WebLogic Server l2c should you take advantage of when designing Disaster Recovery Centers with active - passive mode?（）
A. MAN Clusters, because they would allow you to synchronously replicate state in low latency networks
B. WAN Clusters, because they would allow you to asynchronously replicate state in nonlow latency networks.
C. Transaction Log in the database, because you could avoid synchronizing two replication technologies (database and file)
Data Guard, because it is the most effective way to replicate a state across locations
E. GoldenGate, because it is the most effective way to replicate a state across locatio

A warehouse fact table in your Oracle 12c Database is range-partitioned by month and accessed frequently with queries that span multiple partitions The table has a local prefixed, range partitioned index. Some of these queries access very few rows in some partitions and all the rows in other partitions, but these queries still perform a full scan for all accessed partitions. This commonly occurs when the range of dates begins at the end of a month or ends close to the start of a month. You want an execution plan to be generated that uses indexed access when only a few rows are accessed from a segment, while still allowing full scans for segments where many rows are returned. Which three methods could transparently help to achieve this result?（）
A. Using a partial local Index on the warehouse fact table month column with indexing disabled to the table partitions that return most of their rows to the queries.
B. Using a partial local Index on the warehouse fact table month column with indexing disabled for the table partitions that return a few rows to the queries.
C. Using a partitioned view that does a UNION ALL query on the partitions of the warehouse fact table, which retains the existing local partitioned column.
D. Converting the partitioned table to a partitioned view that does a UNION ALL query on the monthly tables, which retains the existing local partitioned column
E. Using a partial global index on the warehouse fact table month column with indexing disabling for the table partitions that return most of their rows to the queries.
F. Using a partial global index on the warehouse fact table month column with indexing disabled for the table partitions that return a few rows to the queries.
