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

  • A. Add agents for Oracle Enterprise Manager Monitoring.
  • B. Configure for Oracle Enterprise Manager Monitoring.
  • C. Unconfigure for Oracle Enterprise Manager Monitoring.
  • D. 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'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

Which are the four key attributes to set up ZFS storage appliance for Microsoft Exchange?

  • A. Blocksize 4k El
  • B. RAID1

Answer : B,C,D,E

Which two items represent the tradeoffs regarding capacity and performance when deduplication is enabled?

  • A. Netbackup backups will use much less space if stored on a deduplicated share, and performance is not impacted because the workload is sequential.
  • B. Netbackup backups will see little benefit in space utilization, but also little impact on performance due to the sequential writes.
  • C. The effective capacity of disk space may be greatly enhanced with deduplication, and the performance impact will be greatly dependent on the amount of data to be written, the blocksize selected, and whether the DDT stays in ARC (memory) or not.
  • D. Video streams, encrypted data, and precompressed data may see little or no capacity benefit with deduplication, and throughput performance will be degraded, perhaps even significantly.


Answer : A,D

When is the password for the Browser User Interface access set?

  • A. During the initial setup through the ILOM connection
  • B. After logging in through the Browser User Interface, during the configuration phase
  • C. Already set because it is the same user that was used for the ILOM connection
  • D. After logging in through the Browser User Interface and after the configuration is complete


Answer : D

Which disk profile setup usually best serves random read workloads?

  • A. DRAM, followed by pool disks

  • C. DRAM, followed by read cache devices (Readzillas)
  • D. Log devices (Logzillas)
  • E. DRAM, followed by log devices (Logzillas)
  • F. Pool disks


Answer : D

Which three statements are correct about Cluster Configuration of ZFS Storage
Appliances?

  • A. To utilize resource of both nodes simultaneously, you need at least two storage pools: one that maps to node1 and another that maps to node2.
  • B. Clusters can be configured in two ways: Active-Active or Active-Passive.
  • C. Only one controller in a Cluster can be assigned resources.
  • D. You can assign networking and storage pool to a controller in a cluster.
  • E. In Cluster environment, both nodes can be owner of each storage pool.
