Free Teradata Random Questions and Answers

Question 1

What part is in charge of input conversion?

Accepted Answer

PE

Answer

The Parsing Engine (PE) is responsible for input conversion—it receives SQL requests, parses them, and handles data type conversion before dispatching work. The AMP manages data storage and retrieval, BYNET handles inter-component communication, and CLI is the client interface, so none of those performs input conversion.

Question 3

Which will only ever return one Row?

Accepted Answer

Both

Answer

Explanation:
Both UPI (Unique Primary Index) and USI (Unique Secondary Index) can return at most one row for a given value.

Question 4

Because of _____, a uniqueness value is necessary to provide a unique Row ID.

Accepted Answer

Both Answers

Answer

A uniqueness value is needed for the Row ID in both cases: duplicate values in a NUPI (Non-Unique Primary Index) and hash synonyms (different values that hash to the same value) can produce identical hash results, so Teradata adds a uniqueness value to distinguish the rows. Since both scenarios require it, 'Both Answers' is correct.

Question 5

Accepted Answer
