TeraData HCIA-Datacom V1.0 Sample Questions (Q28-Q33):

NEW QUESTION # 28
A capacity planner wants to keep a record of the number of rows that are added and deleted from certain tables over time and would like to obtain this information without having to change the application itself.
Which DBQL option should be enabled?

A. USECOUNT
B. EXPLAIN
C. OBJECTS
D. VERBOSE XMLPLAN

Answer: C

Explanation:
The OBJECTS option in DBQL (Database Query Logging) records the tables and other objects that are accessed by queries, including information on how many rows are added, updated, or deleted. This allows the capacity planner to track changes to specific tables without modifying the application itself.
The other options are less relevant to tracking row changes:
USECOUNT records how often specific queries are executed, but not the number of rows affected.
EXPLAIN captures the query execution plan, which doesn't provide details on rows added or deleted.
VERBOSE XMLPLAN gives detailed execution plans in XML format, but it is more focused on query execution and optimization, not tracking row modifications.

NEW QUESTION # 29
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. Disable the expedite option of the workloads in the SLG Tier level 1.
C. Increase the number of AWTs.
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 # 30
There is corruption in a table in the DBC database.
Which action should the Administrator take to restore the table?

A. Perform a SYSINIT, and restore the entire system.
B. Set the corrupted AMP offline, and restore the corrupted table.
C. Set the corrupted AMP offline, and restore the entire system.
D. Perform a SYSINIT, and restore the corrupted table.

Answer: B

Explanation:
If a table in the DBC (Data Dictionary) database is corrupted, the proper approach is to set the corrupted AMP offline to isolate the issue, and then restore the corrupted table from a backup. This limits the scope of the recovery to only the affected AMP and table, minimizing the impact on the rest of the system.
Perform a SYSINIT, and restore the corrupted table: A SYSINIT is a full system initialization and should only be done in extreme cases, as it wipes the entire system. This is too drastic for table-level corruption.
Set the corrupted AMP offline, and restore the entire system: Restoring the entire system is unnecessary if only one table is corrupted.
Perform a SYSINIT, and restore the entire system: This would be an extreme and time-consuming option, only used if the entire system is corrupted.

NEW QUESTION # 31
An Administrator needs to enforce a security policy which prohibits the use of an application's username from being used by certain query clients.
Which workload management feature should the Administrator use?

A. Filter
B. Utility Session
C. Flex Throttle
D. Exception

Answer: A

Explanation:
Filters in Teradata workload management allow the Administrator to define rules that restrict or block certain types of queries or connections based on specific criteria, such as the username, query client, or other attributes. In this case, the Administrator can use a filter to prevent queries from specific clients using the application's username, enforcing the security policy.
Option A (Flex Throttle) is used to manage query concurrency and system resources dynamically but is not designed to enforce security policies like user restrictions.
Option B (Utility Session) controls the number of utility sessions but does not help with filtering query clients based on usernames.
Option C (Exception) handles query workload exceptions based on certain thresholds or behaviors but doesn't directly enforce user or client restrictions.

NEW QUESTION # 32
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 MACRO
B. CREATE PROCEDURE
C. CREATE AUTHORIZATION
D. CREATE TRIGGER

Answer: C

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.
