Multiple choice technology databases

  1. Which of the following are two architectural attributes of a Teradata System?

  1. Disk space associated with an AMP is divided into three areas: system, permanent and spool

  2. Parallelism is achieved through operating system time slicing

  3. The AMP’s access data from their associated vdisks as required.

  4. The PE’s communicate with the AMP’s across the BYNET

C,D Correct answer
Explanation

Teradata's architecture uses AMPs (Access Module Processors) that each own a portion of data on their associated vdisks - they access this data independently when queries require it. The PEs (Parsing Engines) handle query parsing and send requests to AMPs through the BYNET, which is the high-speed interconnect that enables communication between components. Option A describes disk areas but isn't an architectural attribute, while option B is incorrect because Teradata uses hardware parallelism, not OS time-slicing.
