Question No: 45

Which storage profile serves data the fastest for random disk IOPS?

  1. RAID-Z2

  2. RAID-Z3

  3. RAID-1

  4. RAID-ZR

  5. RAID-5

Answer: E

Explanation: Using RAID-5

The conventional wisdom among database professionals is that RAID-5 is evil and should be avoided regardless of the situation. The primary issue with RAID-5 is that in addition to a parity calculation, each logical write requires many physical writes. The performance effects of this are most keenly felt on systems with a high write percentage, and are made worse in cases where there is not enough RAM. It follows that on systems with a low write percentage, and on those with sufficient memory, RAID-5 may not be such a performance killer as many make it out to be. The bottom line is that, depending on the IO profile and the storage implementation, the performance difference between a RAID-5 and a RAID-10 array may not be discernable at all, and the extra costs of a RAID-10 array may be better spent elsewhere.

Question No: 47

Which two maintenance workflows does the Oracle ZFS Storage plug-in for Oracle Enterprise Manager Grid controller provide?

  1. Add agents for Oracle Enterprise Manager Monitoring.

  2. Configure for Oracle Enterprise Manager Monitoring.

  3. Unconfigure for Oracle Enterprise Manager Monitoring.

  4. Assign agents for Oracle Enterprise Manager Monitoring pool.

Answer: B,C

Explanation: The Sun ZFS Storage plug-in for Oracle Enterprise Manager Grid controller provides first-class monitoring to the grid controller environment for the Sun ZFS Storage appliance family with the ability to:

->Monitor Sun ZFS Storage appliances

->Gather storage system information, configuration information and performance information of accessible storage components

->Raise alerts and violations based on thresholds and monitoring information collected by the tool

->Provide out-of-the-box reports that complement analytics

->Support monitoring by remote agents.

Once an appliance is configured to be monitored by the grid controller, analytics worksheets and datasets are created to bridge the grid controller administrator#39;s view to the deeper level of detail provided by the real-time analytics available within the appliance.

The management plug-in is available at the following link: Oracle Technology Network

It is packaged with an installation guide that should be read by both administrators of the grid controller and storage administrators of appliances being monitored.

Included with each appliance are two workflows that are used respectively to prepare a system for monitoring, or to remove the artifacts created for the monitoring environment:

->Configure for Oracle Enterprise Manager Monitoring

->Unconfigure Oracle Enterprise Manager Monitoring
