TeraData HCIA-Datacom V1.0 Sample Questions (Q58-Q63):

NEW QUESTION # 58
An Administrator is required to load sensor data from cloud storage. This store contains many numeric columns.
Which strategy should the Administrator use to optimize the data load?

  • A. Collect statistics on all payload attributes.
  • B. Cast column data types to appropriate values in a view of the foreign table.
  • C. Keep the original VARCHAR data types in JSON or CSV for columns.
  • D. Use a more generic LOCATION string in the USING clause.

Answer: B

Explanation:
When loading sensor data, especially if it involves many numeric columns, casting the data to appropriate types (like INT, FLOAT, etc.) in a view can significantly improve query performance and reduce storage overhead. This approach ensures that the numeric data is handled efficiently, avoiding unnecessary conversions or using inefficient data types such as VARCHAR.


NEW QUESTION # 59
An application is consuming very high I/O on Teradata Vantage. The Administrator has been asked to identify the queries that are consuming more than 100 million IOs and are suspected of completing Full Table Scans or Large Redistribution.
Which metrics should be examined for high values to identify the queries?

  • A. I/O SKEW % and UII
  • B. MAXAMPIO and PJI
  • C. TOTALIOCOUNT and PJI
  • D. REQPHYSIO and UII

Answer: C

Explanation:
TOTALIOCOUNT represents the total number of I/O operations a query performs, which is crucial when trying to identify queries consuming excessive I/O (in this case, more than 100 million IOs). This directly indicates the amount of I/O a query is generating.
PJI (Product Join Index) measures whether a product join is being performed in the query, which is often associated with inefficient joins that result in large redistributions of data. A high PJI value indicates that the query might be performing a product join, leading to a significant performance hit due to large redistributions.
Option A (MAXAMPIO and PJI): MAXAMPIO refers to the maximum I/O performed by a single AMP, but TOTALIOCOUNT is a more direct indicator of the total I/O performed by a query across all AMPs.
Option C (I/O SKEW % and UII): I/O SKEW % indicates uneven distribution of I/O, which can cause performance issues, but it does not directly measure the total I/O consumption like TOTALIOCOUNT does. UII (Utility Impact Index) is relevant but not as important for identifying large I/O queries.
Option D (REQPHYSIO and UII): REQPHYSIO refers to the number of physical I/Os, but it is not as comprehensive as TOTALIOCOUNT, which includes both logical and physical I/O.
Thus, TOTALIOCOUNT (for total I/O) and PJI (to detect potential large redistributions due to product joins) are the key metrics to identify queries with high I/O and large redistributions.


NEW QUESTION # 60
The data science team reports that they do not have enough memory to run in-database Python scripts when the scripts operate simultaneously.
Which workload management feature should the Administrator use to resolve this issue?

  • A. Planned environments to specify periods when data scientists can run Python scripts
  • B. Exceptions to place Python scripts consuming too much memory into a penalty box
  • C. Throttles to limit the concurrency of Python scripts
  • D. Virtual partitions to assign separate memory space to each Python script

Answer: C

Explanation:
Using throttles in workload management allows the Administrator to limit the concurrency of Python scripts running in the system. By controlling the number of Python scripts that can run simultaneously, you can prevent memory exhaustion and ensure that enough resources are available for each script to execute without causing failures due to memory constraints.


NEW QUESTION # 61
An Administrator has been asked to improve the response time of the workloads in the tactical tier. Workloads are in all tiers of TASM. They are at CPU and I/O capacity, and they have AWT reserved for tactical. The Administrator begins by analyzing the data and the workload prioritization.
Which action should the Administrator take?

  • A. Increase the relative weight of the tactical tier.
  • B. Increase the number of AWTs.
  • C. Disable the expedite option of the workloads in the SLG Tier level 1.
  • D. Adjust the limits of awt concurrency in the tactical tier using DBS control.

Answer: A

Explanation:
In a TASM (Teradata Active System Management) environment, the relative weight of different tiers (such as tactical, SLG, or background) determines the amount of CPU and I/O resources allocated to each tier. Increasing the relative weight of the tactical tier would prioritize these workloads, giving them more resources relative to other tiers and improving their response time.
Option B (Disable the expedite option of the workloads in the SLG Tier level 1) might alleviate some resource pressure from SLG Tier 1 workloads, but it doesn't directly improve the prioritization or resource allocation for tactical workloads.
Option C (Increase the number of AWTs) is not applicable because the system already has reserved AWTs for tactical workloads, and AWT (AMP Worker Task) availability is likely not the bottleneck here. Simply increasing the number of AWTs without addressing the core CPU and I/O resource allocation will not improve tactical workload response.
Option D (Adjust the limits of AWT concurrency in the tactical tier using DBS control) might provide marginal improvements but won't have a significant impact on overall resource prioritization. It focuses more on concurrency management than directly improving workload performance through resource allocation.


NEW QUESTION # 62
An Administrator needs to restrict developers from accessing the Vantage system during the night, between 11:00PM and 05:00AM, but they are permitted to have limited access during the rest of the day.
How should the Administrator accomplish this goal?

  • A. Create a system filter that matches the developers accountstring, and include a classification criteria time window between 11:00PM and 05:00AM.
  • B. Create a Planned Environment that will throttle to zero the concurrency of the developers between 11:00PM and 05:00AM.
  • C. Change any workloads that developers match to have a throttle count of 0.
  • D. Create a health condition that will check which user id is accessing the system, and abort any request that is received between 11:00PM and 05:00AM.

Answer: B

Explanation:
A Planned Environment in Teradata Workload Management allows the Administrator to configure different system behaviors based on time windows. By throttling the concurrency of developer workloads to zero between 11:00 PM and 05:00 AM, the Administrator effectively restricts developers from running queries or jobs during that period. Outside of that time window, you can configure a limited concurrency for the developers.
Option A (Create a system filter): A filter can be used to restrict access based on the accountstring, but it isn't the most efficient way to handle time-based restrictions.
Option B (Create a health condition): This would involve more manual intervention and isn't designed for consistent, scheduled access control like Planned Environments.
Option C (Change workloads to have a throttle count of 0): While throttling the workload could work, Planned Environments provide a more flexible and scheduled approach for handling time-based restrictions.
