(Each answer is used once.)

答案：

解題說明：

問題 #59
An application is consuming very high I/O on Teradata Vantage. The Administrator has been asked to identify the queries that are consuming more than 100 million IOs and are suspected of completing Full Table Scans or Large Redistribution.
Which metrics should be examined for high values to identify the queries?

A. TOTALIOCOUNT and PJI
B. MAXAMPIO and PJI
C. I/O SKEW % and UII
D. REQPHYSIO and UII

答案：A

解題說明：
TOTALIOCOUNT represents the total number of I/O operations a query performs, which is crucial when trying to identify queries consuming excessive I/O (in this case, more than 100 million IOs). This directly indicates the amount of I/O a query is generating.
PJI (Product Join Index) measures whether a product join is being performed in the query, which is often associated with inefficient joins that result in large redistributions of data. A high PJI value indicates that the query might be performing a product join, leading to a significant performance hit due to large redistributions.
Option A (MAXAMPIO and PJI): MAXAMPIO refers to the maximum I/O performed by a single AMP, but TOTALIOCOUNT is a more direct indicator of the total I/O performed by a query across all AMPs.
Option C (I/O SKEW % and UII): I/O SKEW % indicates uneven distribution of I/O, which can cause performance issues, but it does not directly measure the total I/O consumption like TOTALIOCOUNT does. UII (Utility Impact Index) is relevant but not as important for identifying large I/O queries.
Option D (REQPHYSIO and UII): REQPHYSIO refers to the number of physical I/Os, but it is not as comprehensive as TOTALIOCOUNT, which includes both logical and physical I/O.
Thus, TOTALIOCOUNT (for total I/O) and PJI (to detect potential large redistributions due to product joins) are the key metrics to identify queries with high I/O and large redistributions.

問題 #60
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 OUTPUT command.
C. Execute an Alter METHOD command for
D. Purge the request cache.

答案：A

問題 #61
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. Inherited
B. Automatic
C. Ownership
D. Assigned

答案：A

解題說明：
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.

問題 #62
A business' operating periods are event-driven, and the batch window begins and ends at various times of the evening. The Administrator needs to configure TASM to dynamically trigger the reporting planned environment using an API call issued when the batch window ends.
Which type of event can the Administrator use to meet this requirement?

A. User-Defined Event
B. Period Event
C. API Event
D. System Event

答案：A

解題說明：
User-Defined Event is the appropriate event type in TASM (Teradata Active System Management) for dynamically triggering actions based on custom triggers, such as the completion of an event-driven batch window. This event type allows the administrator to define specific conditions or API calls to trigger changes in the system, such as switching to a reporting planned environment.
The other options:
API Event is not a defined event type in TASM.
System Event is used for events triggered by system-level occurrences, such as system state changes or alerts, but not for custom triggers like batch window completion.
Period Event is based on predefined, fixed time intervals, which wouldn't work for the variable timing of the batch window in this scenario.
