Demo Questions

Question 1
Which statement is true about instance caging setup?

  • A: The initialization parameter resource_manager_plan should be set.
  • B: For a system with 16 threads, the sum of cpu_count for all databases should not be higher than 32 to prevent oversubscribing.
  • C: Database instances need to be restarted to make changes to cpu_count effective.
  • D: The CPU Resource Manager and IORM need to be enabled to make instance caging to work as expected.
  • E: Instance caging is the right approach to make sure that database instances are not stealin memory from one another.

Question 2
Which three tools can be used on a freshly re-imaged Exadata system to create, resize, or delete ACFS filesystems? (Choose three.)

  • A: SQL*Plus and ASMCMD
  • B: ASMCA
  • C: Enterprise Manager Express
  • D: Enterprise Manager Cloud Control
  • E: RMAN
  • F: OUI

Question 3
Your government customer has purchased a full rack of Exadata. The customer has two departments that would like to share the Exadata Database Machine but the concern is that department A will be able to see data from department B. 
Which architecture would you suggest to solve this deployment issue?

  • A: Split the configuration by using Oracle Nimbula's cloud software so that four database servers and seven cells can be used by department A and the rest can be used by department B.
  • B: Split the configuration and use ASM-Scoped Security so that four database servers and seven cells can be used by department A and the rest can be used by department B.
  • C: Set up instance caging to ensure that department A has access only to four database servers and seven cells and department B has access to the rest.
  • D: Define the split by setting up database services that are specific to department A and department B.

Question 4
There are many different ways to load data into database tables. 
Which method does Oracle strongly recommend?

  • A: generic connectivity via ODBC or JDBC
  • B: database gateways to open systems and mainframes
  • C: Oracle GoldenGate
  • D: Oracle Data Pump
  • E: SQL*Loader import
  • F: data loading via external tables

Question 5
Which options does not benefit from storage offload processing?

  • A: indexes that rely on B-Tree pointers
  • B: column filtering
  • C: joins and aggregation
  • D: table scans
  • E: incremental backups with block change tracking

Question 6
Your customer would like to configure monitoring capabilities alongside ASR on the stand-alone server that was set aside to run ASR Manager. 
What configuration would you set up for the customer?

  • A: Enterprise Manager, SQL Developer Server, and ASR Manager on the stand-alone server because ASR needs SQL Developer to gain SQL access to the database server
  • B: ASR Manager inside the firewall to ensure that root access to Exadata Database Machine is not compromised
  • C: ASR Manager with SNMP traps configured to listen for specific alerts triggered by Exadata Database Machine
  • D: Enterprise Manager (Ops Center) and ASR Manager on the stand-alone server because ASR is not a monitoring tool

Question 7
Identify three customer options for hosting the Platinum Services Advanced Support Gateway. (Choose three.)

  • A: Purchase the recommended x86 64-Bit gateway hardware from Oracle.
  • B: Install in Oracle Virtual Machine with required hardware.
  • C: Install on Exadata Engineered System.
  • D: Provide individual x86 64-Bit gateway hardware.
  • E: Install on Oracle Database Appliance.

Question 8
Which two statements are true about metrics in the DBMCLI utility? (Choose two.)

  • A: Metric values are computed and stored in memory, and then permanently stored on disk.
  • B: DBMCLI can be used to report on Exadata storage server metrics.
  • C: Metrics are reported as one of four types: cumulative, instantaneous, rate, or transition.
  • D: Fields in AlertHistory cannot be modified.
  • E: DBMCLI reported metrics are informational only and cannot be used to trigger alerts or reported events.

Question 9
What happens in an Exadata Database Machine when the DUPLICATE sub-clause of the INMEMORY attribute is specified?

  • A: The DUPLICATE sub-clause enables parallel execution NUMA support.
  • B: Each In-Memory Compression Unit in the IM column store will have a mirrored copy placed on another node in the RAC cluster.
  • C: The command allows the current instance to exceed DRAM limits and expand across memory, flash, and disk.
  • D: The command creates an in-memory snapshot for write_only access.
  • E: The In-Memory Compression Unit will have a mirrored copy placed on every other node in the RAC cluster.

Question 10
Which statement explains the difference between Normal and High redundancy ASM failure groups?

  • A: Normal redundancy protects the DATA diskgroup, whereas High redundancy protects the RECO diskgroup.
  • B: Normal redundancy (best practice) provides protection against two simultaneous disk failures, whereas High redundancy provides protection against a single disk failure or an entire storage server failure.
  • C: High redundancy gives more usable storage, whereas Normal redundancy provides better I/O performance.
  • D: Normal redundancy protects from disk failure when a cell is offline or being updated, whereas High redundancy protects the system when all the cells are offline.
  • E: Normal redundancy tolerates a single cell failure, whereas High redundancy tolerates a two-cell failure.
