Common Questions About Oracle Exadata Database Machine X8M Implementation Essentials

Oracle Exadata Database Machine X8M Implementation Essentials Sample Questions:

Question 1

How do ASM failure groups provide redundancy?

A. Failure groups are created for each grid disk to ensure mirror copies are written to the same storage server for faster recovery after a physical disk failure.
B. Failure groups contain all ASM disks in a single storage server preventing mirror copies being written to the same storage server.
C. They ensure that the ASM Flex instances are enabled on a maximum of two database servers or VMs per cluster.
D. Extended Redundancy mirrors data across data centers providing the highest levels of data protection.

Question 2

Your customer would like to configure monitoring capabilities Auto Service Request (ASR) on the stand-alone server that was set aside to run ASR Manager.
What configuration should you set up for the customer?

A. Enterprise Manager and ASR Manager on the stand-alone server because ASR is not a monitoring tool.
B. ASR Manager with SNMP traps configured to listen for specific alerts triggered by Exadata Intergrated Lights Out Manager (ILOM).
C. Enterprise Manager, Exachk and ASR Manager on the stand-alone server because ASR needs Exachk for continuous Hardware monitoring.
D. ASR Manager inside the firewall along with ExaWatcher to monitor Database and Storage Server performance.

Question 3

Which two statements are true in regards to starting the Exadata Virtual Machine?

A. To streamline the diagnosis of virtual machines, one ISO file is used for multiple Oracle Exadata System Software releases.
B. Use vm_maker boot-from-iso command to boot a virtual machine.
C. Use vm_maker -start-domain to start a virtual machine manually.
D. To see Oracle Linux boot messages during guest startup, use -console option with the vm_maker -start-domain command.
E. Use vm_maker -auto-start command to configure a virtual machine to start automatically when the KVM host is started.

Question 4

Which statement is true about the disks that are used in ASM diskgroups on the Exadata platform?

A. Sparse diskgroups are virtual objects allocated from the DATA diskgroup.
B. The grid disks in ASM diskgroups must have similar performance characteristics in addition lo having the same size.
C. If High redundancy is selected, grid disks from the primary and secondary Exadata Database Machine must be specified.
D. Extreme Flash (EF) and High Capacity (HC) disks can be mixed to any capacity within the same diskgroup.
E. In an Exadata storage server, each disk is placed into a separate failure group.

Question 5

Your system administrator reports an amber, non-blinking light on one of your Exadata storage disks. You immediately execute the 'list physicaldisk where diskType=HardDisk and status=failed DETAIL' command on the Exadata storage system and the specified disk is indeed reported as failed. Platinum Support has not been enabled for this system. Enterprise Manager Cloud Control is monitoring the system.
What is the next step that you should perform before you do anything else?

A. Call Oracle Support and make an appointment so that the drive can be replaced.
B. Wait for the email of the failure that Exadata or Enterprise Manager will send.
C. Ask the system administrator to replace the broken disk with a spare.
D. Wait for a blue light to appear on the disk if the rebalance operation is running.
E. Download and run the latest exadiag tool.
F. Check the database to see if any rebalance operations are active.
