TeraData HCIA-Datacom V1.0 Sample Questions (Q35-Q40):

NEW QUESTION # 35
Which benefit is achieved by creating profiles?

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

Answer: D

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 # 36
Which spool threshold can an Administrator set to define workload management exception criteria?

A. Hot AMP Spool
B. Max Spool Space By AMP
C. Maximum Spool Rows
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 # 37
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. 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.
D. Change any workloads that developers match to have a throttle count of 0.

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.

NEW QUESTION # 38
Business users are regularly joining a common set of columns from parquet external data to existing dimension tables. An Administrator needs to improve the performance of these queries where they filter on common columns.
Which strategy can be used to improve performance?

A. Create a foreign server to access the data with column partitioning.
B. Row partition the parquet table on the filter columns.
C. Change the primary index of the foreign server to the filtering columns.
D. Create a multi-table join index to cover the joined data.

Answer: D

Explanation:
A multi-table join index pre-joins data from multiple tables and stores the result, allowing subsequent queries that perform similar joins to access the pre-joined data directly. This can significantly improve query performance, especially when there is a common set of columns frequently joined between parquet external data and dimension tables.
Option A (Row partition the parquet table on the filter columns): While row partitioning might improve some performance aspects, it's more suited for managing large datasets within Vantage tables and not as effective for parquet external data access.
Option B (Change the primary index of the foreign server to the filtering columns): There is no "primary index" on foreign servers. Foreign data (like parquet) doesn't use Vantage primary index concepts, so this option is not applicable.
Option C (Create a foreign server to access the data with column partitioning): Column partitioning is not typically applicable to external parquet data accessed through a foreign server in the same way it is for native tables. While you can optimize column access, a multi-table join index is more effective for query performance involving frequent joins.

NEW QUESTION # 39
An Administrator has set up security constraints on columns holding sensitive data through the use of profiles. A user, with an appropriate profile, then issues a select against this sensitive data.
Which type of privilege is being used?

A. Automatic
B. Inherited
C. Assigned
D. Ownership

Answer: B

Explanation:
Inherited privileges are those that a user acquires based on their membership in a profile or role. In this case, the user has been assigned a profile that grants access to sensitive data, meaning the privilege to access that data is inherited through the profile.
Option B (Ownership) refers to the privileges that the creator (owner) of a database object has over that object, but in this case, the user is accessing data through a profile, not ownership.
Option C (Automatic) would suggest that the privilege is granted automatically without the need for an explicit assignment or inheritance, which doesn't apply here because the privileges are coming from a profile.
Option D (Assigned) refers to direct privileges granted to a user individually, but in this scenario, the user is accessing data through a profile, which means the privileges are inherited rather than directly assigned.
