A. update hdfs set D as ‘./output’;
B. store D into ‘./output’;
C. place D into ‘./output’;
D. write D as ‘./output’;
E. hdfsstore D into ‘./output’;

Answer: B

Explanation:
Use the STORE operator to run (execute) Pig Latin statements and save (persist) results to the file system. Use STORE
for production scripts and batch mode processing.
Syntax: STORE alias INTO 'directory' [USING function];
Example: In this example data is stored using PigStorage and the asterisk character (*) as the field delimiter.
A = LOAD 'data' AS (a1:int,a2:int,a3:int);
DUMP A;
(1,2,3)
(4,2,1)
(8,3,4)
(4,3,3)
(7,2,5)
(8,4,3)
STORE A INTO 'myoutput' USING PigStorage ('*');

QUESTION 2
The Hadoop NameNode is running on port #3001, the DataNode on port #4001, the KVStore agent on port #5001, and
the replication node on port #6001. All the services are running on localhost.
What is the valid syntax to create an external table in Hive and query data from the NoSQL Database?

A. CREATE EXTERNAL TABLE IF NOT EXISTSMOVIE( id INT,original_tit1e STRING,overview
STRING)STORED BY 'oracle.kv.hadoop.hive.table.TableStorageHandler'TBLPROPERTIES
("oracle.kv.kvstore"="kvscore","oracle.kv.hosts"="localhost:3001","oracle.kv.hadoop.hosts"
="localhost","oracle.kv.tableName"= MOVIE");

B. CREATE EXTERNAL TABLE IF NOT EXISTSMOVIE( id INT,original_title STRING,overview
STRING)STORED BY 'oracle.kv.hadoop.hive.table.TableStorageHandler'TBLPROPERTIES ("oracle.kv.kvstore "="
kvstore ","oracle.kv.hosts"="localhost:5001","oracle.kv.hadoop.hosts"="localhost","oracle.kv.tab1eN ame"="MOVIE");
C. CREATE EXTERNAL TABLE IF NOT EXISTSMOVIE( id INT,original_title STRING,overview
STRING)STORED BY
'oracle,kv.hadoop.hive.table.TableStorageHandler'TBLPROPERTIES
("oracle.kv.kvstore"="kvstore","oracle.kv.hosts"="localhost:4001","oracle.kv.hadoop.hosts"=
"localhost","oracle.kv.tab1eName"="MOVIE");

D. CREATE EXTERNAL TABLE IF NOT EXISTSMOVIE( id INT,original_title STRING,overview
STRING)STORED BY 'oracle,kv.hadoop.hive.table.TableStorageHandler'TBLPROPERTIES
("oracle.kv.kvstore"="kvstore","oracle.kv.hosts"="localhost:6001","oracle.kv.hadoop.hosts"=
"localhost","oracle.kv.tab1eName"="MOVIE");

Answer: C

Explanation:
The following is the basic syntax of a Hive CREATE TABLE statement for a Hive external table over an Oracle NoSQL table:
CREATE EXTERNAL TABLE tablename colname coltype[, colname coltype,...]
STORED BY 'oracle.kv.hadoop.hive.table.TableStorageHandler'
TBLPROPERTIES (
"oracle.kv.kvstore" = "database",
"oracle.kv.hosts" = "nosql_node1:port[, nosql_node2:port...]",
"oracle.kv.hadoop.hosts" = "hadoop_node1[,hadoop_node2...]",
"oracle.kv.tableName" = "table_name");
Where oracle.kv.hosts is a comma-delimited list of host names and port numbers in the
Oracle NoSQL Database cluster. Each string has the format hostname:port.
Enter multiple names to provide redundancy in the event that a host fails.

QUESTION 3
You need to create an architecture for your customer’s Oracle NoSQL KVStore. The customer needs to store clinical and non-clinical data together but only the clinical data is mission critical.
How can both types of data exist in the same KVStore?

A. Store the clinical data on the master node and the non-clinical data on the replica nodes.
B. Store the two types of data in separate partitions on highly available storage.
C. Store the two types of data in two separate KVStore units and create database aliases to mimic one KVStore.
D. Store the two types of data with differing consistency policies.

Answer: B

Explanation:
The KVStore is a collection of Storage Nodes which host a set of Replication Nodes. Data is spread across the Replication Nodes.
Each shard contains one or more partitions. Key-value pairs in the store are organized according to the key. Keys, in turn,
are assigned to a partition. Once a key is placed in a partition, it cannot be moved to a different partition. Oracle NoSQL
Database automatically assigns keys evenly across all the available partitions.
Note: At a very high level, a Replication Node can be thought of as a single database which contains key-value pairs.
Replication Nodes are organized into shards. A shard contains a single Replication Node which is responsible for
performing database writes, and which copies those writes to the other Replication Nodes in the shard.

QUESTION 4
Your customer is spending a lot of money on archiving data to comply with government regulations to retain data for 10 years.
How should you reduce your customer’s archival costs?

A. Denormalize the data.
B. Offload the data into Hadoop.
C. Use Oracle Data Integrator to improve performance.
D. Move the data into the warehousing database.

Answer: B

Explanation:
Extend Information Lifecycle Management to Hadoop
For many years, Oracle Database has provided rich support for Information Lifecycle Management (ILM). Numerous capabilities are available for data tiering – or storing data in different media based on access requirements and storage cost considerations.

These tiers may scale from
1) in-memory for real time data analysis,
2) Database Flash for frequently accessed data,
3) Database Storage and Exadata Cells for queries of operational data and
4) Hadoop for infrequently accessed raw and archive data:

QUESTION 5
Your customer keeps getting an error when writing a key/value pair to a NoSQL replica.
What is causing the error?

A. The master may be in read-only mode and as result, writes to replicas are not being allowed.
B. The replica may be out of sync with the master and is not able to maintain consistency.
C. The writes must be done to the master.
D. The replica is in read-only mode.
E. The data file for the replica is corrupt.

Answer: C

Explanation:
Replication Nodes are organized into shards. A shard contains a single Replication Node which is responsible for
performing database writes, and which copies those writes to the other Replication Nodes in the shard. This is called the
master node. All other Replication Nodes in the shard are used to service read-only operations.
Note: Oracle NoSQL Database provides multi-terabyte distributed key/value pair storage that offers scalable throughput
and performance. That is, it services network requests to store and retrieve data which is organized into key-value pairs.
