Your customer has 10 web servers that generate logs at any given time. The customer would like to consolidate and load this data as it is generated into HDFS on the Big Data
Appliance.
Which option should the customer use?

• A.Set up a zookeeper agent to capture the transactions and write them to HDFS.
• B.Set up an hbase agent to capture the transactions and write them to HDFS.
• C.Set up a web server agent in Apache Oozie to write the data to HDFS.
• D.Write a hive query to listen for new logs and save them in a Hive table.
• E.Set up a flume agent to capture the transactions and write them to HDFS.

Your customer has three XML files in HDFS with the following contents. Each XML file contains comments made by users on a specific day. Each comment can have zero or more "likes" from other users. The customer wants you to query this data and load it into the Oracle Database on Exadata.
How should you parse this data?

• A.by using the built-in functions for reading JSON in the Oracle XQuery for Hadoop
  Connector
• B.by configuring the Oracle SQL Connector for HDFS and parsing by using SerDe
• C.by using the XML file module in the Oracle XQuery for Hadoop Connector
• D.by creating a table in Hive and using MapReduce to parse the XML data by column

Your customer uses Active Directory to manage user accounts. You are setting up Hadoop
Security for the customer's Big Data Appliance.
How will you integrate Hadoop and Active Directory?

• A.Set up Kerberos' Key Distribution Center to be the Active Directory keystore.
• B.Set up a one-way cross-realm trust from the Active Directory realm to the Kerberos realm.
• C.Configure Active Directory to use Kerberos' Key Distribution Center.
• D.Set up a one-way cross-realm trust from the Kerberos realm to the Active Directory realm.

You are helping your customer troubleshoot the use of the Oracle Loader for Hadoop
Connector in online mode. You have performed steps 1, 2, 4, and 5.
STEP 1: Connect to the Oracle database and create a target table.
STEP 2: Log in to the Hadoop cluster (or client).
STEP 3: Missing step
STEP 4: Create a shell script to run the OLH job.
STEP 5: Run the OLH job.
What step is missing between step 2 and step 4?

• A.Copy the table metadata to the Hadoop system.
• B.Diagnose the job failure and correct the error.
• C.Create an OLH metadata file.
• D.Create an XML configuration file.
• E.Query the table to check the data.

Your customer has a Big Data Appliance and an Exadata Database Machine and would like to extend security. Select two ways that security works in Big Data SQL. (Choose two.)

• A.On the Big Data Appliance, Hadoop's native security is used.
• B.On the Big Data Appliance, Oracle Identity Management is used.
• C.On the Big Data Appliance, data is encrypted by using Oracle Transparent Data
  Encryption (TDE).
• D.On the Exadata Database Machine, Oracle Advanced Security is used for fine-grained access control.
• E.On the Big Data Appliance, Oracle Advanced Hadoop Security is used for fine grained access control.
