문제6

You plan to monitor the status of the motherboard, memory, power, fans, and network cards on the database nodes in your Exadata Database Machine using Enterprise Manager.
Where must you set the thresholds for these hardware components and why, to assure that sensor readings, faults, and any related alerts, are visible in Enterprise Manager?

A. Set thresholds only in ILOM because they are not preset anywhere but need to be set only in ILOM.

B. No thresholds need to be set because they are preset in the ILOM and these are sufficient for monitoring.

C. No thresholds need to be set because they are preset in the ILOM and in Enterprise Manager

D. Set thresholds in ILOM and in Enterprise Manager because they are not preset anywhere and must be set in both places.

문제7

You want to monitor how a large production table is accessed. Especially, you are interested to see how the access on that particular table leverages the benefits of the Exadata Platform.
Which two actions are NOT appropriate for that purpose?

A. You run the CellCli-command list activerequest , filtering for the attributes ioReason and objectNumber, that you specify as 'Smart Scan' and the Object ID of your table from DBA_OBJECTS.

B. You query v$segment_statistics and filter for the Object ID of your table from dba_objects and the the column STATISTIC_NAME='optimized physical reads'.

C. YOU query VSSYSTEM_EVENTS and filter for the event 'cell physical IO interconnect bytes returned by smart scan', associated to your table.

D. You query v$SYSTAT and filter for the statistic 'cell smart table scan', associated to your table.

문제9

How is Exadata Secure RDMA Fabric isolation used in X9M-2 with virtualization enabled?

A. With Secure Fabric isolation, each Storage Server runs multiple KVM guests each dedicated to a Database VM cluster using a dedicated network partition and VLAN ID. This provides security and isolation between multiple tenants or VM clusters.

B. With Secure Fabric isolation, each Database VM Cluster uses a dedicated network partition and VLAN ID for Data Guard networking between the primary and disaster recovery Exadata racks. This improves security by isolating data guard traffic onto an encrypted network between data centers.

C. With Secure Fabric isolation, each Database VM Guest uses a dedicated network partition and VLAN ID for client networking between application servers. This improves security by preventing man in the middle attacks.

D. With Secure Fabric isolation, each Database VM cluster uses a dedicated network partition and VLAN ID for cluster networking between the database servers in the VM Cluster. This provides security and isolation between multiple tenants or VM clusters.
