TeraData HCIA-Datacom V1.0 Sample Questions (Q39-Q44):

NEW QUESTION # 39
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 default profile setting for the user will be reset to NULL.
B. SPOOL and DEFAULT DATABASE specifications for the dropped profile will still apply to the user.
C. The system will show a warning message.
D. Password attributes defined at the system level in DBCSecurityDefaultsV will apply

Answer: D

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 # 40
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 BusinessViews to AcctShared, then grant AcctUsers, AcctDev, and AcctBatch to AcctShared.
B. Grant SELECT on AcctShared to BusinessViews, then grant AcctShared to AcctUsers. AcctDev, and AcctBatch.
C. Grant SELECT on BusinessViews to AcctShared, then grant AcctShared to AcctUsers. AcctDev, and AcctBatch.
D. Grant SELECT on AcctShared to BusinessViews, then grant AcctUsers, AcctDev, and AcctBatch to AcctShared.

Answer: C

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 # 41
After a recent migration, a request has started to take significant time to complete. Upon a detailed investigation of the EXPLAIN plan, it is found that an accidental unconstrained product join on a very uniformly-distributed large table was the prime reason for the issue. The Administrator needs to use workload management to detect when this request is running.
Which criteria should the Administrator select for this issue?

A. CPU Utilization
B. CPU Skew
C. CPU Disk Ratio
D. AWT Wait Time

Answer: B

Explanation:
CPU Skew is a metric that measures the uneven distribution of CPU usage across AMPs (Access Module Processors). In the case of an accidental unconstrained product join on a large, uniformly distributed table, certain AMPs may handle significantly more work than others, leading to high CPU Skew. This skew occurs because the product join results in an inefficient execution plan, where data from the large table is unnecessarily compared row-by-row with another table.
Option A (AWT Wait Time) refers to the time queries spend waiting for available AMP Worker Tasks, but it is not directly related to detecting the inefficiencies caused by product joins.
Option C (CPU Disk Ratio) measures the relationship between CPU usage and disk I/O. While it could indicate inefficiency, it doesn't directly pinpoint product join issues like CPU Skew does.
Option D (CPU Utilization) reflects overall CPU usage but doesn't indicate imbalance across AMPs, which is critical for detecting issues like product joins.

NEW QUESTION # 42
How can an Administrator monitor the data volume that is transferred for a Data Mover job via Viewpoint?

A. By accessing the Completed Queries portlet and selecting the Data Mover job
B. By submitting the datamove status -job_name command in the remote console
C. By using the Data Mover portlet accessing the log tab
D. By viewing the job statistics tab of the Performance Data Collection portlet

Answer: C

Explanation:
The Data Mover portlet in Viewpoint provides specific functionality for managing and monitoring Data Mover jobs. By accessing the log tab within the Data Mover portlet, the Administrator can review detailed logs, including the data volume that was transferred during the job execution.
Option A (Completed Queries portlet) focuses on monitoring and analyzing completed queries but does not provide detailed insights into Data Mover jobs.
Option C (Performance Data Collection portlet) is used for monitoring system performance but is not directly related to Data Mover job details or data transfer volumes.
Option D (datamove status command) is a CLI (Command-Line Interface) method to check job status, but it is not related to monitoring the data volume within the Viewpoint environment.

NEW QUESTION # 43
Which spool threshold can an Administrator set to define workload management exception criteria?

A. Hot AMP Spool
B. Max Spool Space By AMP
C. Spool Skew
D. Maximum Spool Rows

Answer: C

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.
