TeraData HCIA-Datacom V1.0 Sample Questions (Q14-Q19):

NEW QUESTION # 14
After a recent migration, a request has started to take significant time to complete. Upon a detailed investigation of the EXPLAIN plan, it is found that an accidental unconstrained product join on a very uniformly-distributed large table was the prime reason for the issue. The Administrator needs to use workload management to detect when this request is running.
Which criteria should the Administrator select for this issue?

  • A. CPU Disk Ratio
  • B. CPU Skew
  • C. CPU Utilization
  • D. AWT Wait Time

Answer: B

Explanation:
CPU Skew is a metric that measures the uneven distribution of CPU usage across AMPs (Access Module Processors). In the case of an accidental unconstrained product join on a large, uniformly distributed table, certain AMPs may handle significantly more work than others, leading to high CPU Skew. This skew occurs because the product join results in an inefficient execution plan, where data from the large table is unnecessarily compared row-by-row with another table.
Option A (AWT Wait Time) refers to the time queries spend waiting for available AMP Worker Tasks, but it is not directly related to detecting the inefficiencies caused by product joins.
Option C (CPU Disk Ratio) measures the relationship between CPU usage and disk I/O. While it could indicate inefficiency, it doesn't directly pinpoint product join issues like CPU Skew does.
Option D (CPU Utilization) reflects overall CPU usage but doesn't indicate imbalance across AMPs, which is critical for detecting issues like product joins.


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

  • A. Max Spool Space By AMP
  • B. Maximum Spool Rows
  • 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.


NEW QUESTION # 16
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. Use a more generic LOCATION string in the USING clause.
  • C. Cast column data types to appropriate values in a view of the foreign table.
  • D. Keep the original VARCHAR data types in JSON or CSV for columns.

Answer: C

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 # 17
A role, TestingSprint, was created and assigned to members of a testing unit. This role is temporary in nature and will be dropped after the sprint ends. The manager of the testing unit is also assigned to the role and wants to drop it once work is complete.
Which option can the Administrator use to fulfill this request?

  • A. Grant the DROP ROLE privilege to a newly created role, and then grant that role to the manager.
  • B. Re-grant the TestingSprint role to the manager, specifying the WITH GRANT OPTION.
  • C. Grant the DROP ROLE privilege to the TestingSprint role.
  • D. Re-grant the TestingSprint role to the manager, specifying the WITH ADMIN OPTION.

Answer: D

Explanation:
Granting a role with the WITH ADMIN OPTION allows the recipient (in this case, the manager) to not only use the role but also manage it. This includes the ability to drop the role when it is no longer needed, as requested by the manager.


NEW QUESTION # 18
There is a call center application that repetitively sends tactical queries to Vantage These queries use a few small tables that are joined on the primary index column.
The following maps are defined in the system:
* TD_GlobalMap
* TD_Map1
* TD_DataDictionaryMap
* TD_1AmpSparseMap_1Node
What can be done to optimize these queries?

  • A. Assign these tables to TD_Map1 using the same colocation name for every table.
  • B. Assign these tables to TD_1AmpSparseMap_1Node using different colocation names for each table.
  • C. Assign these tables to TD_1AmpSparseMap_1Node using the same colocation name for every table
  • D. Assign these tables to TD_Map1 using different colocation names for each table.

Answer: C

Explanation:
Example:
TD_1AmpSparseMap_1Node is a sparse map that assigns the data to a single AMP (or a few AMPs), and using the same colocation name ensures that the tables are collocated on the same AMP. This helps in efficient joining because no data redistribution is required between AMPs when tables are joined on the primary index.
Using different colocation names for each table (options A and D) would place the tables on different AMPs, leading to less efficient joins since data would need to be shuffled between AMPs.
TD_Map1 is a predefined map in the system but does not specifically optimize small, frequently accessed tables in the same way that TD_1AmpSparseMap_1Node does, which is more suitable for these scenarios.
Thus, using the same colocation name within the TD_1AmpSparseMap_1Node ensures that the joins are AMP-local, optimizing the repetitive tactical queries.
