Question#1

An Administrator received reports that a high priority business intelligence (BI) report is failing. This report is a large transaction comprised of multiple SQL statements. Analysis revealed that a TASM filter is rejecting one of the SQL statements in the transaction, and this is causing the entire report to fail.
Which workload management adjustment could the Administrator take to prevent this report from failing?

A. Add the application ID for the report to the filter Bypass list.

B. Define a new workload for the high priority report.

C. Enable prevent mid-transaction throttle delay.

D. Add exclusion criteria for multistatement requests to the filter.

Explanation:
By adding the application ID for the high-priority report to the filter Bypass list, the TASM (Teradata Active System Management) filter will no longer reject any SQL statements from this specific report. This ensures that the entire report can execute successfully without one of its statements being blocked, thereby preventing the report from failing.

Question#2

Which spool threshold can an Administrator set to define workload management exception criteria?

A. Maximum Spool Rows

B. Spool Skew

C. Hot AMP Spool

D. Max Spool Space By AMP

Explanation:
Spool Skew is a threshold that an Administrator can set in workload management to detect and manage uneven distribution of spool space usage across AMPs (Access Module Processors). When spool skew exceeds a certain threshold, it can trigger exception handling or corrective actions, helping to prevent performance degradation caused by unbalanced resource utilization.
The other options are less commonly used for defining workload management exception criteria:
Maximum Spool Rows: This is not a standard threshold for workload management.
Hot AMP Spool: While this refers to uneven spool space usage on a specific AMP, spool skew is the more appropriate term and metric used for setting thresholds.
Max Spool Space By AMP: This isn't a standard workload management threshold. Spool space limits are generally applied system-wide or per user, not by AMP.

Question#3

An Administrator notices that a system appears to be near capacity and needs to access a dictionary to assess that AMPs are entering into flow control.
Which dictionary should be accessed for this purpose?

A. DB

B. SessionInfoV

C. DB

D. ResUsageSawt

E. DB

F. AMPUsage

G. DB

H. ResUsageSldv

Explanation:
The DBC.ResUsageSawt view provides detailed information about the resource usage of AMP Worker Tasks (AWTs), including whether AMPs are experiencing flow control. Flow control occurs when AMPs are overwhelmed and need to throttle the workload, and this view tracks metrics related to AWT usage and system resource contention, which would indicate when AMPs are under strain.
Option A (DBC.SessionInfoV) provides information about current user sessions but does not provide insights into AMP-level flow control or resource usage.
Option C (DBC.AMPUsage) provides general statistics about AMP usage but doesn't give detailed information about flow control or AWT usage.
Option D (DBC.ResUsageSldv) tracks statistics related to logical disk usage but isn't focused on AMP flow control.

Question#4

A customer is complaining that the creation of a large table in the lab environment is getting stuck in the merge step. The customer is using the following command to create the table: CREATE TABLE ... AS (SELECT * ...) WITH DATA
Which recommendation will help the merge step?

A. A column that provides good distribution should be specified as PRIMARY INDE

B. The MERGEBLOCKRATIO should be specified for the table to improve the data block merge operation.

C. The table should be created with "CREATE TABLE ... AS (SELECT *...) WITH NO DATA", and afterwards, "INSERT ... SELECT *" should be used to fill the table.

D. Users of the lab may have lower priority than other workloads, so the creation of the table should be moved to off-peak hours.

Explanation:
Merge step issues often occur when a large amount of data is being processed during the table creation, especially if the system is trying to simultaneously create the table and insert data.
By using "WITH NO DATA", the table structure is created first, without the actual data being inserted during the table creation process. The *"INSERT ... SELECT " command can then be used afterwards to populate the table in a more controlled way, reducing the load on the system during the creation phase and potentially improving the efficiency of the merge step.
Specifying a good distribution for the primary index can help overall performance, but it doesn't directly address the issue with the merge step in this scenario.
Specifying the MERGEBLOCKRATIO isn't typically a solution for this specific problem; the merge block ratio is more about the optimization of data block merges rather than the creation of tables.
Moving the creation to off-peak hours may help if the environment is busy, but it doesn't directly address the core issue of the merge step getting stuck.

Question#5

The Administrator has just created a new database object on a Vantage system.
Which privilege is NOT automatically granted to that database on itself?

A. CREATE AUTHORIZATION

B. CREATE MACRO

C. CREATE PROCEDURE

D. CREATE TRIGGER

Explanation:
When a new database object is created in Teradata Vantage, certain object creation privileges (such as CREATE MACRO, CREATE PROCEDURE, and CREATE TRIGGER) are typically granted automatically to the database or user who created the object.
However, the CREATE AUTHORIZATION privilege, which allows a user to create an authorization object (used for external authentication to external systems, such as a cloud storage service), is not automatically granted. This privilege requires an explicit grant.
