Block level operations are performed against populated tables by which utility?

  1. Tpump

  2. BulKLoad

  3. FastLoad

  4. MultiLoad


Correct Option: D

AI Explanation

To answer this question, you need to understand the utility used for block level operations against populated tables.

Option A) Tpump - This option is incorrect because Tpump is a Teradata utility used for continuous data loading and updating.

Option B) BulKLoad - This option is incorrect because there is no Teradata utility named BulKLoad.

Option C) FastLoad - This option is incorrect because FastLoad is a Teradata utility used for fast loading of data into empty tables.

Option D) MultiLoad - This option is correct because MultiLoad is a Teradata utility used for block level operations against populated tables. It allows for efficient loading, updating, and deleting of data from tables.

The correct answer is D) MultiLoad. This option is correct because MultiLoad is the utility used for block level operations against populated tables.

  1. All data rows are copied into temporary space

  2. Each data block for a table is read

  3. Each data row is accessed only one

  4. A random set of data blocks for a table is read


Correct Option: B,C
  1. When choosing a primary index you should pick a column with a severely limited value set

  2. If distribution is skewed an all-AMP operation will take longer than if all AMPs were evenly utilized

  3. Selecting a NUPI for storing data provides for maximum efficiency and makes the best use of the parallel features of Teradata

  4. The degree of uniqueness is not critical ot efficiency.


Correct Option: B

Which are two exclusive features of Teradata? (Choose two)

  1. Mature optimizer

  2. Industry standard access language(SQL)

  3. Concurrent users

  4. Parallel architecture


Correct Option: A,D
  1. Teradata Manager

  2. BTEQ

  3. Teradata SQL Assistant

  4. TDQM


Correct Option: D

You are an administrator at CertKiller.com. CertKiller.com has a Teradata system with 100 GB of permanent space, of which 50 GB is reserved for spool space. The system currently has 30 GB of user data. What is the total available spool space for user queries?

  1. 70 GB

  2. 50GB

  3. 30 GB

  4. 80 GB


Correct Option: A

AI Explanation

To calculate the total available spool space for user queries, we need to subtract the amount of user data from the reserved spool space.

Given information:

  • Total permanent space = 100 GB
  • Reserved spool space = 50 GB
  • Current user data = 30 GB

To calculate the available spool space, we subtract the current user data from the reserved spool space: Available spool space = Reserved spool space - Current user data

Substituting the given values: Available spool space = 50 GB - 30 GB Available spool space = 20 GB

Therefore, the total available spool space for user queries is 20 GB.

  1. It is based on the Secondary Index

  2. It is based on the primary key of the table

  3. It is on the partitioning column

  4. It is based on the Primary Index of the table


Correct Option: D

A Partitioned Primary Index should be used for what two reasons? (Choose two)

  1. It is the Primary Key of the table, which guarantees uniqueness

  2. It allows instantaneous dropping of old data and rapid addition of new data

  3. It avoids full table scans without the overhead of a secondary index.

  4. It places all data in a specific range on the same AMP.


Correct Option: C,D

  2. creating a report show how much credit can be extended to a customer

  3. creating a report that shows the top ten selling items across all stores for one year

  4. updating a checking account to reflect a deposit


Correct Option: D

You are an administrator at CertKiller.com. CertKiller.com has a Teradata system with 100 GB of permanent space and creates User A with 30 GB permanent space. How much spaces will User A have, if User A creates User B with 20 GB permanent space?

  1. 70GB

  2. 80GB
