Question: 2 
What is the purpose of the Netezza External Tables feature? 
A. To store large unstructured data files. 
B. To import/export data between Netezza and external systems. 
C. To enable parallel execution of SQL statements in Netezza. 
D. To provide real-time streaming data processing capabilities. 
E. 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.

Question: 3 
Which statement accurately describes the purpose of Netezza Zone Maps? 
A. Zone maps are used for data replication across Netezza clusters. 
B. Zone maps enable parallel execution of SQL statements in Netezza. 
C. Zone maps store query plans for optimizing query performance. 
D. Zone maps provide statistical information for data distribution in Netezza. 
E. 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.

Question: 5 
Which Netezza component is responsible for executing user queries? 
A. Snippet processor 
B. Query optimizer 
C. Host database 
D. SPU (Snippet Processing Unit) 
E. 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? 
A. Zone maps are used to store metadata about database objects. 
B. Zone maps store statistical information about table data distribution. 
C. Zone maps are used for data encryption in Netezza. 
D. Zone maps are utilized for query optimization in Netezza. 
E. 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? 
A. To store user data in a structured format. 
B. To maintain metadata about the Netezza system and its objects. 
C. To provide a graphical user interface for system administration. 
D. To handle system-level security and access control. 
E. 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.
