1 Database Accounting_DB is defined with 5 GB of PERM space. It has a User_Accounts table and 5 views defined in it. While loading 2 GB of data into the empty User_Accounts, the load process failed with a message that there is no more Perm Space in Accounting_DB. Which is a valid reason for the failure?

The Views are getting built, due to the load process.

User_Accounts has a PI defined that it is causing skewing.

The user id used for loading data does not have enough Perm space.

Table is defined with Fallback.

2 The customer is maintaining two identical systems in a Dual Active Data Warehouse environment. Teradata Query Director is being used to route the traffic between these two systems. Which statement is true about this situation?

If one system fails,Teradata Query Director redirects new sessions to the fail over system based on the rules defined in Teradata Query Director.

Teradata Query Director redirects the sessions based on the rules defined for sessions originating from load utilities or business queries to balance the workload across the two systems.

If one system is verybusy,Teradata Query Director will redirect some query sessions to the other system, while load activity will be redirected based on the rules defined in Teradata Query Director.

To useTeradata Query Director, there must be two active Teradata systems installed and in operation.

4 What is a benefit of extrapolated and propagated statistics?

No statistics need to be collected.

Statistics only need to be collected once.

There is less need for frequent statistics collection.

Statistics are automatically collected as a background process.

5 While executing the FastLoad job to load a Fallback table, a database full condition occurs during End Loading Phase (Phase 2). Which action needs to be performed to complete the load?

Assign more space, remove the Begin Loading command from the script, and resubmit the script.

Assign more space, specify the checkpoint number in the Begin Loading command in the script, and resubmit the script.

Assign more space, remove the DEFINE and INSERT commands from the script, and resubmit the script.

Assign more space, remove the End Loading command from the script, and resubmit the script.

6 A system is continually running out of AMP Worker Tasks (AWT) and failing to meet business service level agreements (SLAs). The database administrator determines that the best method to solve the problem is to use TDWM to manage the workload. Which feature in TDWM should be used to limit the number of queries for an application?

Throttles

Events

States

Filters

d

8 Which characteristic is true about AMP Worker Tasks (AWTs)?

They are limited to 64 per AMP.

They can be reserved for special use.

Additional AWTs are created as they are needed.

Currently running AWTs will shutdown if they haven't been used in 20quantums.

9 A data integration job is used to load large amounts of historical data into a single table. The job has failed because there is no more room in the database which contains the target table. The administrator has examined the distribution of the data across AMPs and found that the data is distributed evenly. The administrator cannot get additional Perm Space from any other databases. Which two actions will reclaim Perm Space and allow the data integration job to complete? (Choose two.)

Run PACKDISK.

Remove unnecessary Secondary Indexes from tables in the target database.

Drop unnecessary statistics.

Drop views and macros from the database.

14 A table with 200 GB of data is in an active data warehouse environment. Approximately 20-30% of the data is being updated nightly using BTEQ. Business rules require that this table remain available 24x7 for user access and updates. Space limitations have prevented fallback from being defined for this table. Which two types of data protection are needed to allow continuous user access while ensuring the data can be recovered in the event of data loss or corruption? (Choose two.)

Implement permanent journaling for the table.

Implement AMP clusters for the non-fallback table.

Implement a daily dictionary archive.

Implement a daily online archive.

16 A user USERA has failed with the following error: 2646 No more spool space in USERA. What should be analyzed to identify the possible root cause?

18 A customer has an Active Data Warehouse and restricts database access during financial monthend close, allowing only data loads and a limited number of power users to access the system. Which process should be used to implement the restrictions?

Using the state matrix, define a state that includes a throttle for the power users during the financial month-end period.

Define a throttle rule that limits power users, make it a global rule, and make the power users and data loads bypass users.

Make sure the power users have the same default account string, create a filter, and make it a global rule.

Define a filter with a logon rule that identifies data loads and power users, make it a global rule, and assign it to the financial month-end period.
