   Answer: A, E

Explanation: The SQL Extension toolkit package contains various files necessary for extending the functionality of IBM Netezza Performance Server. When extracting the package, you will find the following files:

A. libnetinza-version.tar.gz: This file contains the Netezza libraries required for SQL extension.

E. libnetsqlkit-version.tar.gz: This file contains the SQL Extension toolkit, which includes additional functions, operators, and procedures for Netezza.

Question: 2

What is the purpose of the Netezza External Tables feature?

1. To store large unstructured data files.

2. To import/export data between Netezza and external systems.

3. To enable parallel execution of SQL statements in Netezza.

4. To provide real-time streaming data processing capabilities.

5. To encrypt sensitive data stored in Netezza.
   
   Answer: B

Explanation: The Netezza External Tables feature is used to import and export data between Netezza and external systems. It allows Netezza to access data stored in external sources, such as flat files or remote databases, and load it into Netezza tables or extract data from Netezza tables and export it to external destinations. This feature facilitates data integration and exchange between Netezza and other systems.

Question: 3

Which statement accurately describes the purpose of Netezza Zone Maps?

1. Zone maps are used for data replication across Netezza clusters.

2. Zone maps enable parallel execution of SQL statements in Netezza.

3. Zone maps store query plans for optimizing query performance.

4. Zone maps provide statistical information for data distribution in Netezza.

5. Zone maps are used for data backup and recovery in Netezza.
   
   Answer: D

Explanation: Netezza Zone Maps provide statistical information for data distribution in the system. They store metadata about the distribution of data within tables, allowing the query optimizer to make informed decisions when executing queries. Zone maps help optimize query performance by determining data placement and distribution across the Netezza system.

Question: 4

Which statement accurately describes the purpose of Netezza Replication?

1. Netezza Replication is used for automatic failover and high availability.

2. Netezza Replication enables parallel execution of SQL statements.

3. Netezza Replication provides advanced data compression techniques.

4. Netezza Replication ensures data consistency across multiple Netezza

   servers.

5. Netezza Replication is used for query optimization.
   
   Answer: A

Explanation: Netezza Replication is used for automatic failover and high availability.

Question: 5

Which Netezza component is responsible for executing user queries?

1. Snippet processor

2. Query optimizer

3. Host database

4. SPU (Snippet Processing Unit)

5. Load utility
   
   Answer: D

Explanation: The Snippet Processing Unit (SPU) is the Netezza component responsible for executing user queries. Each SPU is equipped with processing power and memory to handle query execution tasks efficiently. The SPU processes snippets of SQL statements in parallel, enabling high-performance query processing.

Question: 6

Which statement is true about Netezza Zone Maps?

1. Zone maps are used to store metadata about database objects.

2. Zone maps store statistical information about table data distribution.

3. Zone maps are used for data encryption in Netezza.

4. Zone maps are utilized for query optimization in Netezza.

5. Zone maps are used for data compression in Netezza.
   
   Answer: B

Explanation: In Netezza, zone maps store statistical information about table data distribution. They provide valuable metadata that helps optimize query execution by determining data placement and distribution across the system. Zone maps are not used for metadata storage, data encryption, data compression, or query optimization.

Question: 7

What is the purpose of the Netezza Performance Server System Catalog?

1. To store user data in a structured format.

2. To maintain metadata about the Netezza system and its objects.

3. To provide a graphical user interface for system administration.

4. To handle system-level security and access control.

5. To manage data replication across multiple Netezza servers.
   
   Answer: B

Explanation: The Netezza Performance Server System Catalog is used to maintain metadata about the Netezza system and its objects. It stores information about databases, tables, views, indexes, users, privileges, and other system-related details. The System Catalog is essential for managing and administering the Netezza system.
