TeraData HCIA-Datacom V1.0 Sample Questions (Q11-Q16):

NEW QUESTION # 11
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?

A. Space
B. AWT
C. I/O
D. CPU

Answer: C

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.

NEW QUESTION # 12
How can an Administrator monitor the data volume that is transferred for a Data Mover job via Viewpoint?

A. By accessing the Completed Queries portlet and selecting the Data Mover job
B. By using the Data Mover portlet accessing the log tab
C. By submitting the datamove status -job_name command in the remote console
D. By viewing the job statistics tab of the Performance Data Collection portlet

Answer: B

Explanation:
The Data Mover portlet in Viewpoint provides specific functionality for managing and monitoring Data Mover jobs. By accessing the log tab within the Data Mover portlet, the Administrator can review detailed logs, including the data volume that was transferred during the job execution.
Option A (Completed Queries portlet) focuses on monitoring and analyzing completed queries but does not provide detailed insights into Data Mover jobs.
Option C (Performance Data Collection portlet) is used for monitoring system performance but is not directly related to Data Mover job details or data transfer volumes.
Option D (datamove status command) is a CLI (Command-Line Interface) method to check job status, but it is not related to monitoring the data volume within the Viewpoint environment.

NEW QUESTION # 13
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. DBC.AMPUsage
B. DBC.ResUsageSldv
C. DBC.SessionInfoV
D. DBC.ResUsageSawt

Answer: D

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.

NEW QUESTION # 14
An Administrator has been presented with these performance metrics from the DBQLOGTBL table for four queries:

The Administrator needs to identify which query is suspected to be causing a full table scan or large redistribution.
Which query is producing this result?

A. QRY_D because of CPU SKEW
B. QRY_C because of UII
C. QRY_B because of IO SKEW
D. QRY_A because of PJI

Answer: C

NEW QUESTION # 15
Which spool threshold can an Administrator set to define workload management exception criteria?

A. Maximum Spool Rows
B. Max Spool Space By AMP
C. Hot AMP Spool
D. Spool Skew

Answer: D

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.
