Question No. 1

Identify the four software components that run only on an Exadata Database Machine Database Server.

Answer: A, C, D, F
 

Question No. 2

You must apply patches and patch bundles in a rolling fashion, if possible, on the components of your Exadata X6 Database Machine.

You use RAC for your databases and also use Data Guard, having standby databases on another Database Machine.

You want to have scripts that contain the appropriate commands to patch your environment.

Your patch bundle is one the first database server and is located at /uo1/stage.

You have downloaded the oplan utility to the first database server and run:

$ORACLE_HOME/oplan/oplan generateApplySteps /u01/stage

Which two statements are true concerning the type of instructions oplan will generate?

Answer: A, C

Oplan generates instructions for all of the nodes in the cluster.

Note:

Question No. 3

You are planning your deployment of Enterprise Manager to monitor all the components of an X5 Database Machine.

A part of the requirement is to provide for high availability of the monitoring infrastructure.

If the host running the agent that has Database Machine targets bound to it fails, the monitoring of these targets must be done by another agent.

Which three statements are true regarding the configuration used to support this requirement?

Answer: B, C, E
 

Question No. 4

You are patching your Exadata X6 Database Machine by applying a new image to the Storage Servers in a rolling fashion.

Your ASM environment on the Database Machine has five diskgroups stored on an unpartitioned Exadata storage grid, with redundancy settings as shown:

1. DATA_DBM1 -- Normal Redundancy

2. RECO_DBM1 -- Normal Redundancy

3. DBFS_DG -- Normal Redundancy

4. DATA2_DBM1 -- High Redundancy

5. DATA3_DBM1 High Redundancy

Which two diskgroups will not suffer from any data loss throughout the patching process even if there is a single disk failure on one of the cells

Answer: D, E

HIGH redundancy provides protection against 2 simultaneous disk failures from 2 distinct storage servers or 2 entire storage servers. HIGH redundancy provides redundancy during Exadata storage server rolling upgrades.

Question No. 5

Which two activities are supported on the storage servers in an Exadata X6 Database Machine?

Answer: A, C
 

Question No. 6

An important application has been migrated to a database on an X5 Database Machine.

You are examining high-load SQL statements from this application, in an attempt to determine which ones will benefit from the Exadata Smart Scan capability.

Which three access paths always generate 'cell single block physical read' or 'cell multiblock physical read' requests?

Answer: A, C, F
 

Question No. 7

You issued these commands to all Exadata Storage Servers in an X6 Exadata Database Machine using dcli:

alter iormplan objective = low_latency

alter iormplan active

There are no database or category plans defined.

You are encountering disk I/O performance problems at certain times, which vary by day and week.

DSS and Batch workloads perform well some of the time.

Further investigation shows that at times, the workloads are all OLTP I/Os, at other times all batch I/Os, and sometimes a bit of each.

You wish to have disk I/O managed so that performance will be optimized for all workloads.

Which statements would you issue to all Exadata Storage Servers to achieve this?

Answer: D

The supported IORM objectives are auto, low_latency, balanced, and high_throughput. The recommended objective option is auto which allows IORM to continuously monitor the workloads, and select the best mode based on the active workloads currently on the cells.

Question No. 8

Which three statements are true about bulk data loading capabilities in an X5 Database Machine environment?

Answer: B, C, D

External tables on DBFS file-systems provide the probably the most high-performance way to bulk load data into your database.

Bulk Data Loading

Describe the various options for staging data to be bulk loading into Database Machine

Configure the Database File System (DBFS) feature for staging input data files

Use external tables based on input data files stored in DBFS to perform high-performance data loads
