A table that contains about two billion records is showing a bad response time for range-based queries on the order date column and frequently projects 10 out of 100 columns. The Administrator decides to convert the table to a column and row partitioned table.
Which resource is constrained?

  1. I/O
  2. CPU
  3. AWT
  4. Space

Answer(s): A

Explanation:

The table contains about two billion records and is exhibiting poor response time for range-based queries on the order date column, along with frequently projecting only 10 out of 100 columns. These factors indicate that the I/O (Input/Output) subsystem is under strain, as large amounts of data are being scanned and retrieved unnecessarily for each query. Row and column partitioning can significantly reduce the amount of data that needs to be read from disk by limiting I/O to only the necessary partitions (rows) and columns, thus improving performance.
CPU might also be involved, but in this case, the primary concern appears to be I/O due to the large volume of data being retrieved and processed inefficiently. AWT (AMP Worker Tasks) and Space are less likely to be the primary issues based on the problem description, as there is no mention of concurrency issues (AWT) or running out of space.



Which privilege category is granted to a user on a newly created object?

  1. Ownership
  2. Explicit
  3. Inherited
  4. Automatic

Answer(s): A

Explanation:

When a user creates an object (such as a table, view, or database), they automatically receive ownership privileges on that object. This means the creator has full control over the object, including the ability to grant or revoke access to other users, modify the object, and drop it if necessary. Option B (Explicit) refers to privileges that are specifically granted by an owner or an administrator, but in this case, the privileges are automatically granted by virtue of object creation. Option C (Inherited) refers to privileges a user inherits through roles or profiles, but that's not relevant to the automatic ownership granted upon object creation. Option D (Automatic) could be misleading here.
While ownership privileges are granted automatically, the correct term for the type of privilege is ownership.



An Administrator is working through a set of tasks to set up a new Vantage system. The current task is to set up alerts to trigger BTEQ scripts to run when certain conditions are met.
Which action should an Administrator take?

  1. Define a delivery setting to run SQL.
  2. Ensure the SMTP host is using TLS.
  3. Configure an action set specifying BTEQ.
  4. Specify BTEQ in a SNMP Trap.

Answer(s): C

Explanation:

Action sets in Teradata Vantage allow the administrator to define a set of actions that should occur when certain conditions (alerts) are triggered. In this case, the action set should be configured to run a BTEQ script when the conditions are met. This approach ensures that specific automated responses (such as running BTEQ scripts) are executed in response to alerts. Option A (Define a delivery setting to run SQL) refers to running SQL commands but does not involve triggering BTEQ scripts, which is what the question requires. Option B (Ensure the SMTP host is using TLS) is related to secure email notifications and is unrelated to running BTEQ scripts.
Option D (Specify BTEQ in a SNMP Trap) refers to Simple Network Management Protocol traps, which are used for network monitoring and not directly for triggering BTEQ scripts.



A group of batch queries that rely on QueryGrid to source data from a cloud Vantage system has failed and requires urgent investigation.
Which Viewpoint portlet should be used to initially investigate the reason for this problem? A group of batch queries that rely on QueryGrid to source data from a cloud Vantage system has failed and requires urgent investigation.
Which Viewpoint portlet should be used to initially investigate the reason for this problem?

  1. Query Spotlight
  2. Alert Viewer
  3. Productivity
  4. Completed Queries

Answer(s): B

Explanation:

The Alert Viewer portlet in Viewpoint is designed to show system alerts and failures. Since the issue is urgent and involves failed queries using QueryGrid, the Alert Viewer is the appropriate place to start the investigation. It will display any alerts or failures related to QueryGrid, system connectivity, or resource constraints, providing insight into what might have caused the batch queries to fail. Option A (Query Spotlight) is more focused on analyzing the performance of individual queries but may not directly highlight system or connection issues related to QueryGrid failures. Option C (Productivity) gives insights into system usage and workload management, but it's not the primary tool for troubleshooting failed queries.
Option D (Completed Queries) shows details about successfully completed queries but is not the best place to start for investigating failed queries that require urgent attention.
