• C.CELLSRV: The Cell Server is responsible for servicing disk I/O and predicate processing offload.
• D.RS: The Restart Server is responsible for CELLSRV and MS monitoring and restart.
• E.MS: The Management Server is responsible for starting a local Enterprise Manager agent.
• F.MS: The Management Server is responsible for storage cell management and configuration.

Which three statements are true about Automatic Degree of Parallelism (Auto DOP) on Exadata?

• A.Auto DOP is disabled by default and must be enabled before SQL statements can take advantage of its features.
• B.Auto DOP is an exclusive feature in Exadata, which allows the database optimizer to evaluate each statement and run it in parallel without special hints.
• C.Oracle's Auto DOP algorithms calculate the Degree ofParallelism based on the table's block counts.
• D.Auto DOP is enabled by default on Oracle 11gR2, allowing full use of its features.
• E.SQL statements that take advantage of Auto DOP am be identified by using data from Oracle Automatic Workload Repository (AWR) or Enterprise Manager's Monitored SQL Executions page.

Which three statements accurately describe update of software on Exadata Database Machine?

• A.The Oracle Database software on Exadata is updated using standard OPatch and the Oracle Universal Installer.
• B.Storage server updates require access to an Unbreakable Linux Network (ULN) based repository.
• C.Rolling patching is faster than non-rolling patching, but database down time is longer.
• D.The Oracle Database patchset software (for example, 11.2.0.3) requires the Exadata-specific version.
• E.Running Exadata with different storage server software versions is supported, but should be minimized to rolling patching scenarios.
• F.The database server operating system software (other than kernel and OFED) may be installed or updated from non-Exadata sources
