TeraData HCIA-Datacom V1.0 Sample Questions (Q22-Q27):

NEW QUESTION # 22
A role, TestingSprint, was created and assigned to members of a testing unit. This role is temporary in nature and will be dropped after the sprint ends. The manager of the testing unit is also assigned to the role and wants to drop it once work is complete.
Which option can the Administrator use to fulfill this request?

  • A. Grant the DROP ROLE privilege to the TestingSprint role.
  • B. Grant the DROP ROLE privilege to a newly created role, and then grant that role to the manager.
  • C. Re-grant the TestingSprint role to the manager, specifying the WITH GRANT OPTION.
  • D. Re-grant the TestingSprint role to the manager, specifying the WITH ADMIN OPTION.

Answer: D

Explanation:
Granting a role with the WITH ADMIN OPTION allows the recipient (in this case, the manager) to not only use the role but also manage it. This includes the ability to drop the role when it is no longer needed, as requested by the manager.


NEW QUESTION # 23
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 # 24
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. Assigned
  • B. Automatic
  • C. Ownership
  • D. Inherited

Answer: D

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.


NEW QUESTION # 25
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 PROCEDURE
  • B. CREATE AUTHORIZATION
  • C. CREATE MACRO
  • D. CREATE TRIGGER

Answer: B

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.


NEW QUESTION # 26
A customer is complaining that the creation of a large table in the lab environment is getting stuck in the merge step. The customer is using the following command to create the table:
CREATE TABLE ... AS (SELECT * ...) WITH DATA
Which recommendation will help the merge step?

  • A. Users of the lab may have lower priority than other workloads, so the creation of the table should be moved to off-peak hours.
  • B. The table should be created with "CREATE TABLE ... AS (SELECT *...) WITH NO DATA", and afterwards, "INSERT ... SELECT *" should be used to fill the table.
  • C. The MERGEBLOCKRATIO should be specified for the table to improve the data block merge operation.
  • D. A column that provides good distribution should be specified as PRIMARY INDEX.

Answer: B

Explanation:
Merge step issues often occur when a large amount of data is being processed during the table creation, especially if the system is trying to simultaneously create the table and insert data.
By using "WITH NO DATA", the table structure is created first, without the actual data being inserted during the table creation process. The *"INSERT ... SELECT " command can then be used afterwards to populate the table in a more controlled way, reducing the load on the system during the creation phase and potentially improving the efficiency of the merge step.
Specifying a good distribution for the primary index can help overall performance, but it doesn't directly address the issue with the merge step in this scenario.
Specifying the MERGEBLOCKRATIO isn't typically a solution for this specific problem; the merge block ratio is more about the optimization of data block merges rather than the creation of tables.
Moving the creation to off-peak hours may help if the environment is busy, but it doesn't directly address the core issue of the merge step getting stuck.
