TeraData HCIA-Datacom V1.0 Sample Questions (Q62-Q67):

NEW QUESTION # 62
An Administrator has created a new view, ViewDB.SystemMetrics, that combines and aggregates several key system metrics. The data is non-secure in nature, and the intent is for all Vantage users to have SELECT access to it.
Which statement can the Administrator execute to meet this goal?

  • A. GRANT SELECT ON ViewDB.SystemMetrics TO ALL;
  • B. GRANT SELECT ON ViewDB.SystemMetrics TO PUBLIC;
  • C. GRANT SELECT ON ViewDB.SystemMetrics TO DEFAULT;
  • D. GRANT SELECT ON ViewDB.SystemMetrics TO DBC;

Answer: B

Explanation:
PUBLIC is a special keyword in Teradata that refers to all users on the system. Granting privileges to PUBLIC will automatically apply those privileges to every user, including future users, without the need to grant permissions individually.
Option A (GRANT SELECT ON ViewDB.SystemMetrics TO ALL) is not valid because ALL is not a recognized keyword for granting privileges to all users in Teradata.
Option C (GRANT SELECT ON ViewDB.SystemMetrics TO DBC) would grant the privilege to the DBC user (the system database user), but this would not provide access to all users.
Option D (GRANT SELECT ON ViewDB.SystemMetrics TO DEFAULT) is not a valid syntax in Teradata for granting privileges.
GRANT SELECT ON ViewDB.SystemMetrics TO PUBLIC; will allow all users to have SELECT access to the view.


NEW QUESTION # 63
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. Cast column data types to appropriate values in a view of the foreign table.
  • B. Use a more generic LOCATION string in the USING clause.
  • C. Collect statistics on all payload attributes.
  • D. Keep the original VARCHAR data types in JSON or CSV for columns.

Answer: A

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 # 64
An Administrator is configuring an alert service on a Vantage system and must define threshold levels and triggers for the alerts.
Match the Administrator's portlet to the correct use definition.
(Each answer is used once.)

Answer:

Explanation:


NEW QUESTION # 65
The Administrator has dropped a profile which was associated with a group of users.
What will happen when one of the users from the group logs on to the database?

  • A. The system will show a warning message.
  • B. The default profile setting for the user will be reset to NULL.
  • C. Password attributes defined at the system level in DBCSecurityDefaultsV will apply
  • D. SPOOL and DEFAULT DATABASE specifications for the dropped profile will still apply to the user.

Answer: C

Explanation:
When a profile is dropped, the users who were associated with that profile will no longer have the specific resource and configuration settings defined by that profile. Instead, the system-level default settings, such as those specified in DBC.SecurityDefaultsV, will apply to the users. This includes password attributes and other system-wide settings.
Option A (The default profile setting for the user will be reset to NULL) is not accurate, as the system will revert to the default settings rather than leaving values unset.
Option C (The system will show a warning message) does not typically occur when a profile is dropped. The system will manage the transition without user-facing warnings at login.
Option D (SPOOL and DEFAULT DATABASE specifications for the dropped profile will still apply to the user) is incorrect because once the profile is dropped, its settings no longer apply to the users who were associated with it.
Thus, the correct outcome is that system-level attributes defined in DBC.SecurityDefaultsV will govern the users' settings moving forward.


NEW QUESTION # 66
A user runs a number of large, complex queries that regularly generate insufficient memory errors. The Administrator increases the value of the MaxParseTreeSegs DBS control field in order to allocate more parse tree segments to the parser for parsing requests.
Which action must be taken before the queries will run without memory errors?

  • A. The user should log out and log back in to a new session.
  • B. Execute an Alter METHOD command for
  • C. Purge the request cache.
  • D. Execute an OUTPUT command.

Answer: A
