TeraData HCIA-Datacom V1.0 Sample Questions (Q70-Q75):

NEW QUESTION # 70
An Administrator manages a Vantage system that is continually updated. The system is critical to the business and must be available as much as possible. The Administrator decides to use a backup strategy that will allow changes to tables while a backup is in progress.
Which backup strategy should be used?

  • A. Online
  • B. Skip statistics
  • C. Dictionary Only
  • D. Offline

Answer: A

Explanation:
An Online backup strategy allows the database to remain accessible and operational while the backup is taking place. This means that users can continue to modify data, and the system can remain available without requiring downtime. It is a common approach for mission-critical systems that need to maximize uptime.
Offline would require the system or certain tables to be unavailable during the backup process, which is not suitable for a system that needs to remain available.
Skip statistics refers to skipping the backup of statistics on database objects and does not relate to whether the system can be updated during the backup.
Dictionary Only involves backing up only the system catalog or dictionary data, not the actual table data, and would not fulfill the requirement of a comprehensive backup while allowing updates.


NEW QUESTION # 71
A client is having many problems with a poorly written SQL. They have product joins running against large tables, and this is causing severe performance issues. The Administrator needs to help the client avoid the harm to the system that is being caused by running these queries.
Which action should be taken by the Administrator to assist this client?

  • A. Use the Query Spotlight Viewpoint portlet to deprioritize the queries.
  • B. Use a TASM system filter.
  • C. Use the Query Log Viewpoint portlet to identity and abort the harmful queries.
  • D. Use the Flex Throttle option.

Answer: B

Explanation:
Teradata Active System Management (TASM) allows the system administrator to control and manage query workload in real-time. A TASM system filter can be used to prevent or deprioritize certain types of queries, such as product joins or poorly written queries, that are consuming excessive resources. This approach ensures that problematic queries do not harm the overall system performance.
Query Spotlight Viewpoint portlet focuses on identifying and managing individual queries but does not provide the same level of proactive filtering and control as TASM system filters.
Flex Throttle is useful for controlling the concurrency of queries, but it doesn't specifically address preventing or managing product joins in a way that would directly resolve the issue with poorly written SQL.
Query Log Viewpoint portlet would help in identifying and aborting harmful queries, but it's a reactive approach rather than a proactive solution like using TASM system filters.


NEW QUESTION # 72
An Administrator wants to see the list of foreign servers and their parameters in a Teradata QueryGrid configuration for a Vantage system.
Which database shows this information?

  • A. TD_SERVER_DB
  • B. TD_FOREIGN_DB
  • C. SECADMIN
  • D. TD_SYSFNLIB

Answer: A

Explanation:
TD_SERVER_DB contains the metadata for foreign servers and their configurations in a Teradata QueryGrid environment. This includes information about the foreign servers and their associated parameters, which is useful for managing and monitoring QueryGrid connections.
The other options are not directly relevant for this purpose:
TD_SYSFNLIB contains system functions and is unrelated to QueryGrid server configurations.
TD_FOREIGN_DB is not a valid database in the context of QueryGrid configuration.
SECADMIN is related to security and user management but does not contain information about foreign servers in QueryGrid.


NEW QUESTION # 73
The Administrator has received a request to add SELECT rights on the BusinessViews database to end users, developers, and batch accounts in the accounting unit. The following roles are set up for each group:

The Administrator created the AcctShared role and will use it in a role nesting strategy to provide the required access.
Which actions can the Administrator take to fulfill this request?

  • A. Grant SELECT on AcctShared to BusinessViews, then grant AcctUsers, AcctDev, and AcctBatch to AcctShared.
  • B. Grant SELECT on BusinessViews to AcctShared, then grant AcctShared to AcctUsers. AcctDev, and AcctBatch.
  • C. Grant SELECT on BusinessViews to AcctShared, then grant AcctUsers, AcctDev, and AcctBatch to AcctShared.
  • D. Grant SELECT on AcctShared to BusinessViews, then grant AcctShared to AcctUsers. AcctDev, and AcctBatch.

Answer: B

Explanation:
The AcctShared role should be granted SELECT access on the BusinessViews database. This ensures that the role itself has the necessary privileges.
Then, you can nest this role by granting AcctShared to the individual roles of AcctUsers, AcctDev, and AcctBatch. This role nesting strategy allows the users in these groups to inherit the permissions from AcctShared without having to directly grant the privileges to each individual role.
This approach maintains a clean and efficient permission structure using role nesting.


NEW QUESTION # 74
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 DBC;
  • C. GRANT SELECT ON ViewDB.SystemMetrics TO PUBLIC;
  • D. GRANT SELECT ON ViewDB.SystemMetrics TO DEFAULT;

Answer: C

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.
