1.Which three statements are true about Automatic Hard Disk Scrubbing and repair on high-capacity storage servers in an X5 Database Machine? A. Disk repair is made immediately from Smart Flash Cache for corruption on disk when the corresponding data is clean in the Smart Flash Cache. B. Hard disks are scanned every two weeks by default but only when disks are idle. C. Hard disks are scanned every two weeks by default in all situations. D. Disk repair is made immediately from Smart Flash Cache for corruption on disk when the corresponding data is dirty in the Smart Flash Cache. E. Disk repair may be made from another mirror copy if the corrupt area is part of a Normal or High Redundancy Disk Group. Answer: A,C,E

2.You plan to migrate a database supporting an OLTP workload to your new X5 Database Machine.The current database instance supports a large number of short duration sessions and a very high volume of short transactions.Which three X5 Database Machine features can improve performance for this type of workload? A. An improved highly efficient undo and redo architecture B. Faster optimization due to an Exadata-specific optimizer C. Reduced I/O latency for writes due to writeback flashcache on all Exadata X5 and later models D. Ultra high I/O performance for reads and writes when using Exadata Extreme Flash in X5 and later models E. Reduced I/O latency for reads due to read flashcache on all Exadata X5 and later models Answer: A,C,D

3.Your X6 Exadata Database Machine is running Oracle Database 12c, and has a large database with some very large tables supporting OLTP workloads.High-volume insert applications and high-volume update workloads access the same tables.You wish to compress these tables without causing unacceptable performance overheads to the OLTP workload.Which three are true regarding this requirement? A. Compression is performed on database servers when using row store compress advanced in an Exadata environment. B. Using row store compress advanced will compress the data more than if using column store compress for archieve low. C. The compression method column store compress for archive high is the worst fit for this requirement. D. Compression is performed on Exadata Storage Servers when using row store compress advanced in an Exadata environment. E. Using row store compress advanced will compress the data less than if using column store compress forquery low. Answer: A,B,D

4.You plan to migrate a database supporting both DSS and OLTP workloads to your new X5 Database machine.The workloads contain many complex aggregating functions and expensive joins on large partitioned tables in the DSS workload and indexed access for OLTP workloads.Which three benefits accrue as a result of this migration? A. Superior compression capability designed specifically for OLTP workloads B. Columnar storage capability for data in row major data blocks that is held in flash cache C. Superior compression capability designed specifically for data warehouse tables D. Superior compression capability designed specifically for archival data E. Superior flash cache compression technique F. Cell offload processing for indexed-organized table access Answer: A,C,D

5.Which four are true about Exadata features? A. Storage Indexes persist across Exadata storage server reboots. B. Data Warehouse workloads will benefit from Smart Flash Cache configured in Write-Through mode. C. Hybrid Columnar Compressed tables can be compressed and decompressed on Exadata storage servers. D. Hybrid Columnar Compressed tables can be compressed and decompressed on the database servers. E. OLTP workloads will benefit from Smart Flash Cache configured in Write-Back mode. F. Storage Indexes persist across database server reboots. Answer: C,D,E,F

6.Which two must be true for a Smart Scan to occur on a table? A. Sessions querying the table must set cell_offload_processing = true. B. It must be stored in an ASM diskgroup with a 4MByte AU size. C. It must be heap organized. D. It must be accessed using direct path reads. E. The table must not be compressed. Answer: A,D

7.Which three must be true for a Smart Scan to occur for a table? A. cell_offload_processing must be true in sessions issuing SQL statements that access the table. B. The query must be executed serially. C. The query must be executed in parallel. D. Direct path reads must be used at run time. E. The ASM diskgroup containing the table’s tablespace must have a 4 Mbyte AU size. F. The ASM diskgroup containing the table’s tablespace must have cell.smart_scan_capable set to true. Answer: A,D,F

8.A file contains a script with several EXACLI commands that must be executed on each cell in an X5 full rack.The script must run on each cell simultaneously.How would you achieve this? A. Copy the script to all cells using the DCLI command and manually execute it on each cell using the DCLI command. B. Copy the script to the cells using the EXACLI command and execute the script on all cells using the EXACLI command. C. Execute it on all cells using the EXADCLI command specifying the file name containing the EXACLI script. D. Copy the script to all cells using the CELLCLI command and execute it on all cells in parallel using the CELLCLI command. E. Execute it on all cells using the DBMCLI command specifying the file name containing the EXACLI script. Answer: C
