TeraData HCIA-Datacom V1.0 Sample Questions (Q23-Q28):

NEW QUESTION # 23
An Administrator has been given a task to generate a list of users who have not changed their password in the last 90 days.
Which DBC view should be used to generate this list?

  • A. DBC.LOGONOFFV
  • B. DBC.SECURITYDEFAULTSV
  • C. DBC.USERSV
  • D. DBC.ACCESSLOGV

Answer: C

Explanation:
DBC.USERSV contains information about users, including the passwordlastmodified column, which records the date and time the user last changed their password. By querying this view, the Administrator can identify users who have not updated their password within the specified time frame (in this case, 90 days).
Option A (DBC.LOGONOFFV) logs user logon and logoff events, but it does not track password changes.
Option C (DBC.SECURITYDEFAULTSV) contains system-wide security defaults, but it does not track individual user password activity.
Option D (DBC.ACCESSLOGV) logs access control events, like who accessed which database objects, but it doesn't track password changes either.
Therefore, DBC.USERSV is the appropriate view to use for this task.


NEW QUESTION # 24
A Vantage instance includes the following four databases:
Tables Database contains base tables and associated index subtables
Upsert_Database: contains views and other objects to support base table modifications Query Database: contains views and other objects supporting queries and reporting Development_Database: contains objects supporting development of new data applications The Administrator needs to add a new user that will perform batch-level functions.
Which action should the Administrator take to achieve this goal?

  • A. Set the user's profile to one that has the CREATE TABLE privilege on the Tables_Database.
  • B. Grant the CHECKPOINT privilege on the Tables_Database to the new user's account.
  • C. Set the user's default role to one that has the CREATE TABLE privilege on the Tables_Database.
  • D. Grant the CHECKPOINT privilege on the Tables_Database to the new user's profile.

Answer: A

Explanation:
Batch-level functions often involve creating and modifying tables as part of large data loads or updates. To allow the new user to perform these functions, the Administrator should assign them a profile that grants appropriate permissions, such as the CREATE TABLE privilege on the Tables_Database, where base tables are stored.
Profiles are a common way to manage and control resource and security settings for users in Teradata, and assigning a profile with the CREATE TABLE privilege ensures that the user can create tables in the specified database without granting excessive privileges.
Option A (Grant the CHECKPOINT privilege on the Tables_Database): The CHECKPOINT privilege is related to checkpointing transactions, which is not directly relevant to batch-level functions involving table creation or modification.
Option B (Set the user's default role to one that has the CREATE TABLE privilege): While setting a default role can grant privileges, using a profile is a more scalable way to manage user resource and privilege settings, especially if the profile already exists with the necessary permissions.
Option D (Grant the CHECKPOINT privilege on the Tables_Database to the new user's profile): Again, the CHECKPOINT privilege is not directly related to the batch-level activities such as creating tables.


NEW QUESTION # 25
Partition elimination enhances query performance by skipping row partitions that do not contain rows that meet the search conditions of a query. Without collected statistics for some partitioning expressions, the Optimizer assumes a total of 65,535 partitions. This could easily be far more than the number of populated partitions and would adversely affect performance.
Which form of partitioning will cause the Optimizer to make this assumption?

  • A. Partitioning on a character column
  • B. Basing the partitioning expression on a CASE_N function
  • C. Basing the partitioning expression on a RANGE_N character column
  • D. Basing the partitioning expression on two or more numeric columns

Answer: B

Explanation:
CASE_N partitioning is a complex form of partitioning that can result in a large number of potential partitions. When statistics are not collected for the partitioning expressions, the Optimizer assumes the worst-case scenario of 65,535 partitions, which can significantly affect query performance.
Option A (Partitioning on a character column) and Option C (Basing the partitioning expression on two or more numeric columns) could affect performance, but they don't lead to the specific assumption of 65,535 partitions unless more complex functions are involved.
Option D (Basing the partitioning expression on a RANGE_N character column) involves range-based partitioning, which is typically more straightforward and doesn't automatically cause the assumption of 65,535 partitions unless complex expressions like CASE_N are used.


NEW QUESTION # 26
Which benefit is achieved by creating profiles?

  • A. Assigning permanent space for groups of users with similar needs
  • B. Defining spool space for groups of users with similar needs
  • C. Managing user privileges on database objects
  • D. Reducing the growth of the DBC.AccessRights table

Answer: B

Explanation:
Profiles in Teradata are used to manage and enforce resource limits for groups of users. This includes defining spool space, temporary space, and permanent space for users who share similar needs. Spool space is important for query processing, and managing it by profile helps prevent individual users from consuming excessive resources and ensures better overall system performance.
Reducing the growth of the DBC.AccessRights table is not directly related to profiles. Profiles do not reduce access rights or the growth of this table, which tracks individual user privileges.
Managing user privileges on database objects is handled through roles and grants, not profiles. Profiles focus on resource management, not privileges.
Assigning permanent space for groups of users is partially true since profiles can manage some space attributes, but the main focus of profiles is on managing spool space rather than permanent space.


NEW QUESTION # 27
Which view contains privilege checks for user requests?

  • A. DBC.AccessLogV
  • B. DBC.AllRightsVX
  • C. DBC.AccLogRulesV
  • D. DBC.UserRightsV

Answer: A

Explanation:
DBC.AccessLogV contains details regarding access logging, including privilege checks for user requests.
This view provides information about when users' actions are logged, specifically in relation to access attempts and whether these actions are allowed or denied based on their privileges.
