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
