最新的 Vantage Master TDVAN5 免費考試真題 (Q20-Q25):

問題 #20
An Administrator needs to perform a cleanup task on the LOAD_ISOLATED table Employee_Address, which has grown in size.
Which lock is placed on the table when the Administrator performs clean up of the logically deleted rows?

A. ROW ACCESS
B. EXCLUSIVE
C. IREAD
D. WRITE

答案：D

解題說明：
When performing cleanup tasks such as deleting logically deleted rows, the WRITE lock is typically applied. This lock ensures that the Administrator can modify the data in the table (such as removing logically deleted rows) while preventing other users from accessing the table for write operations. However, it allows other users to read from the table.
Other lock types:
ROW ACCESS allows reading specific rows without blocking other access, which is not suitable for cleanup tasks.
EXCLUSIVE locks the entire table for both reading and writing, which is generally too restrictive for this kind of operation.
READ only allows read access and does not permit any modifications, which would prevent the cleanup task from being performed.

問題 #21
An Administrator is working through a set of tasks to set up a new Vantage system. The current task is to set up alerts to trigger BTEQ scripts to run when certain conditions are met.
Which action should an Administrator take?

A. Define a delivery setting to run SQL.
B. Ensure the SMTP host is using TLS.
C. Configure an action set specifying BTEQ.
D. Specify BTEQ in a SNMP Trap.

答案：C

解題說明：
Action sets in Teradata Vantage allow the administrator to define a set of actions that should occur when certain conditions (alerts) are triggered. In this case, the action set should be configured to run a BTEQ script when the conditions are met. This approach ensures that specific automated responses (such as running BTEQ scripts) are executed in response to alerts.
Option A (Define a delivery setting to run SQL) refers to running SQL commands but does not involve triggering BTEQ scripts, which is what the question requires.
Option B (Ensure the SMTP host is using TLS) is related to secure email notifications and is unrelated to running BTEQ scripts.
Option D (Specify BTEQ in a SNMP Trap) refers to Simple Network Management Protocol traps, which are used for network monitoring and not directly for triggering BTEQ scripts.

問題 #22
An Administrator notices that a system appears to be near capacity and needs to access a dictionary to assess that AMPs are entering into flow control.
Which dictionary should be accessed for this purpose?

A. DBC.SessionInfoV
B. DBC.ResUsageSldv
C. DBC.AMPUsage
D. DBC.ResUsageSawt

答案：D

解題說明：
The DBC.ResUsageSawt view provides detailed information about the resource usage of AMP Worker Tasks (AWTs), including whether AMPs are experiencing flow control. Flow control occurs when AMPs are overwhelmed and need to throttle the workload, and this view tracks metrics related to AWT usage and system resource contention, which would indicate when AMPs are under strain.
Option A (DBC.SessionInfoV) provides information about current user sessions but does not provide insights into AMP-level flow control or resource usage.
Option C (DBC.AMPUsage) provides general statistics about AMP usage but doesn't give detailed information about flow control or AWT usage.
Option D (DBC.ResUsageSldv) tracks statistics related to logical disk usage but isn't focused on AMP flow control.

問題 #23
What is the maximum payload size for CSV and JSON data formats that the NOS_READ function can read, when it is based on the LATIN character set?

A. 16 MB
B. 32 MB
C. 8 GB
D. 2 GB

答案：B

解題說明：
When using the NOS_READ function in Teradata to read data in CSV and JSON formats based on the LATIN character set, the maximum payload size that can be read is 32 MB. This limit ensures efficient processing and handling of large datasets, while also maintaining performance.

問題 #24
Which view contains privilege checks for user requests?

A. DBC.UserRightsV
B. DBC.AccessLogV
C. DBC.AllRightsVX
D. DBC.AccLogRulesV

答案：B

解題說明：
DBC.AccessLogV contains details regarding access logging, including privilege checks for user requests.
This view provides information about when users' actions are logged, specifically in relation to access attempts and whether these actions are allowed or denied based on their privileges.
