TeraData HCIA-Datacom V1.0 Sample Questions (Q40-Q45):

NEW QUESTION # 40
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. Execute an OUTPUT command.
B. Execute an Alter METHOD command for
C. The user should log out and log back in to a new session.
D. Purge the request cache.

Answer: C

NEW QUESTION # 41
There is corruption in a table in the DBC database.
Which action should the Administrator take to restore the table?

A. Perform a SYSINIT, and restore the entire system.
B. Perform a SYSINIT, and restore the corrupted table.
C. Set the corrupted AMP offline, and restore the entire system.
D. Set the corrupted AMP offline, and restore the corrupted table.

Answer: D

Explanation:
If a table in the DBC (Data Dictionary) database is corrupted, the proper approach is to set the corrupted AMP offline to isolate the issue, and then restore the corrupted table from a backup. This limits the scope of the recovery to only the affected AMP and table, minimizing the impact on the rest of the system.
Perform a SYSINIT, and restore the corrupted table: A SYSINIT is a full system initialization and should only be done in extreme cases, as it wipes the entire system. This is too drastic for table-level corruption.
Set the corrupted AMP offline, and restore the entire system: Restoring the entire system is unnecessary if only one table is corrupted.
Perform a SYSINIT, and restore the entire system: This would be an extreme and time-consuming option, only used if the entire system is corrupted.

NEW QUESTION # 42
Which Viewpoint portlet can an Administrator use to track the live progress of a long running QueryGrid query?

A. Query Spotlight
B. Query Monitor
C. Completed Queries
D. Today's Statistics

Answer: B

Explanation:
The Query Monitor portlet provides real-time monitoring of active queries, including QueryGrid queries. It shows the live progress of the query, details about its execution, and allows administrators to monitor long-running queries as they are processed.
Option B (Query Spotlight) is more focused on detailed analysis of query performance issues but is typically used after a query has completed.
Option C (Today's Statistics) shows aggregated statistics and system-level metrics but doesn't provide live tracking of individual query progress.
Option D (Completed Queries) shows details about queries that have already finished, so it wouldn't be suitable for tracking an ongoing query.

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. 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 # 44
An Administrator has been tasked with analyzing previous growth and usage patterns by utilities such as Multiload and FastLoad. The aim is to project the likely resource requirements of the existing loads in the next three to six months.
In the last month, the Administrator team have started using AccountString expansion on all user accounts and have started maintenance jobs to housekeep system data older than seven years. Two years ago, the following command was issued on the system:
BEGIN QUERY LOGGING WITH ALL ON ALL;
No other logging commands have been issued.
Which view contains the utility usage data for the prior months?

A. QryLogUtilityV
B. QryLogV
C. LogOnOffV
D. AMPUsageV

Answer: A

Explanation:
QryLogUtilityV is a specific DBQL (Database Query Logging) view that provides information about utility usage (such as Multiload and FastLoad) on the system. Since the BEGIN QUERY LOGGING WITH ALL ON ALL command was issued two years ago, the DBQL (Database Query Logging) has been tracking various events, including utility usage, which is stored in QryLogUtilityV.
Option A (AMPUsageV) contains AMP (Access Module Processor) level statistics and usage data but not detailed information about utility jobs.
Option B (LogOnOffV) tracks user logon and logoff activities but does not provide information about utility usage.
Option D (QryLogV) logs general query execution data but is not specifically focused on utility usage.
