最新的 Qlik Replicate QREP 免費考試真題 (Q52-Q57):

問題 #52
In addition to connection string, username/password. and permission to the database, which element must be present to add a new source endpoint in Qlik Replicate?

A. Access to database server
B. Database client
C. Transactional logs
D. File access

答案：C

解題說明：
To add a new source endpoint in Qlik Replicate, in addition to the connection string, username/password, and permission to the database, the presence of transactional logs is essential. Transactional logs are crucial because they record all changes made to the database, which Qlik Replicate uses to capture the data changes that need to be replicated.
Here's the process of adding a new source endpoint:
Access to the system: You must have access to the system where the endpoint resides.
Connection information: Provide the connection string, which includes the network address and other parameters needed to connect to the source database.
User credentials: Supply the username and password that have the necessary permissions to access the database.
Transactional logs: Ensure that transactional logs are available and accessible because Qlik Replicate uses these logs to track changes in the source database for replication purposes.
The requirement for transactional logs is consistent with the nature of Qlik Replicate's operation, which relies on change data capture (CDC) technology to detect and replicate database changes12.
It's important to note that while the database client (option A) and access to the database server (option D) are also important components in the overall setup, they are not specifically required to add a new source endpoint in the context of this question. File access (option B) is not directly related to the addition of a source endpoint in Qlik Replicate.

問題 #53
Theconnection to the source endpoint is unavailable over several days. The log files contain only 2 hours of data before being deleted. Which Is the safest way to create a consistent state in the target endpoint?

A. Resume task and ignore warnings
B. Use Reload Target Run option
C. Start processing changes from a fixed date and time
D. Recover from a locally stored checkpoint

答案：B

解題說明：
When the connection to the source endpoint is unavailable for an extended period, and the log files are limited to only 2 hours of data before being deleted, the safest way to ensure a consistent state in the target endpoint is to use theReload Target Run option (A). This approach is recommended because it allows for a complete refresh of the target data, ensuring that it is in sync with the source once the connection is re-established.
TheReload Target Run optionis designed to handle situations where the replication logs are not sufficient to recover the replicated state due to extended outages or log retention policies. Byreloading the target, you can be confident that the data reflects the current state of the source, without relying on potentially incomplete change logs.
Starting processing from a fixed date and time (B) or recovering from a locally stored checkpoint would not be reliable if the logs do not cover the entire period of the outage. Resuming the task and ignoring warnings (D) could lead to inconsistencies due to missed changes.
Therefore, theReload Target Run optionis the safest method to create a consistent state in the target endpoint under these circumstances1.

問題 #54
The Apply batched changes to multiple tables concurrently option in a Qlik Replicate task is enabled Which Information can be stored in the attrep_apply_exceptlon Control table?

A. Information about Task_Name, Table_Name, Warning_Time, Statement, Error_description
B. Information about Task_Name. Table_Name. Error_Time. Statement. Error
C. Zero information are stored
D. Information about Task_Name. Table_Name. Warnlng_Tlme. Statement. Error

答案：B

問題 #55
Which is the minimum role permission that should be selected for a user that needs to share status on Tasks and Server activity?

A. Designer
B. Admin
C. Viewer
D. Operator

答案：C

解題說明：
To determine the minimum role permission required for a user to share status on Tasks and Server activity in Qlik Replicate, we can refer to the official Qlik Replicate documentation. According to the documentation, there are four predefined roles available: Admin, Designer, Operator, and Viewer. Each role has its own set of permissions.
The Viewer role is the most basic role and provides the user with the ability to view task history, which includes the status on Tasks and Server activity.This role does not allow the user to perform any changes but does allow them to share information regarding the status of tasks and server activity1.
Here is a breakdown of the permissions for the Viewer role:
View task history: Yes
Download a memory report: No
Download a Diagnostics Package: No
View and download log files: No
Perform runtime operations (such as start, stop, or reload targets): No Create and design tasks: No Edit task description in Monitor View: No Delete tasks: No Export tasks: No Import tasks: No Change logging level: No Delete logs: No Manage endpoint connections (add, edit, duplicate, and delete): No Open the Manage Endpoint Connections window and view the following endpoint settings: Name, type, description, and role: Yes Click the Test Connection button in the Manage Endpoint Connections window: No View all of the endpoint settings in the Manage Endpoint Connections window: No Edit the following server settings: Notifications, scheduled jobs, and executed jobs: No Edit the following server settings: Mail server settings, default notification recipients, license registration, global error handling, log management, file transfer service, user permissions, and resource control: No Specify credentials for running operating system level post-commands on Replicate Server: No Given this information, the Viewer role is sufficient for a user who needs to share status on Tasks and Server activity, making it the minimum role permission required for this purpose1.

問題 #56
Using Qlik Replicate, how can the timestamp shown be converted to unlx time (unix epoch - number of seconds since January 1st 1970)?

A. strftime('%s*,SAR_H_COMMIT_TIMESTAMP) - <code>datetime.datetime</code>('%s','1970-01-01
00:00:00')
B. strftime*'%s,,SAR_H_COMMIT_TIMESTAMP) - strftime('%s','1970-01-01 00:00:00')
C. Time.now.strftime(%s','1970-01-01 00:00:00')
D. SELECT datetime<1092941466, 'unixepoch*, 'localtime');
E. SELECT datetime(482340664, 'localtime', 'unixepoch');

答案：B

解題說明：
The goal is to convert a timestamp to Unix time (seconds since January 1, 1970).
Thestrftimefunction is used to format date and time values.
To get the Unix epoch time, you can use the command:strftime('%s',SAR_H_COMMIT_TIMESTAMP) - strftime('%s','1970-01-01 00:00:00').
This command extracts the Unix time from the timestamp and subtracts the Unix epoch start time to get the number of seconds since January 1, 1970. This is consistent with the Qlik Replicate documentation and SQL standard functions for handling date and time conversions.
To convert a timestamp to Unix time (also known as Unix epoch time), which is the number of seconds since January 1st, 1970, you can use thestrftimefunction with the%sformat specifier in Qlik Replicate. The correct syntax for this conversion is:
strftime('%s', SAR_H_COMMIT_TIMESTAMP) - strftime('%s','1970-01-01 00:00:00') This function will return the number of seconds between theSAR_H_COMMIT_TIMESTAMPand the Unix epoch start date. Here's a breakdown of the function:
strftime('%s', SAR_H_COMMIT_TIMESTAMP)converts theSAR_H_COMMIT_TIMESTAMPto Unix time.
strftime('%s','1970-01-01 00:00:00')gives the Unix time for the epoch start date, which is0.
Subtracting the second part from the first part is not necessary in this case because the Unix epoch time is defined as the time since1970-01-01 00:00:00. However, if the timestamp is in a different time zone or format, adjustments may be needed.
The other options provided do not correctly represent the conversion to Unix time:
Options A and B usedatetimeinstead ofstrftime, which is not the correct function for this operation1.
Option C incorrectly includes<code>datetime.datetime</code>, which is not a valid function in Qlik Replicate and seems to be a mix of Python code and SQL1.
Option E usesTime.now.strftime, which appears to be Ruby code and is not applicable in the context of Qlik Replicate1.
Therefore, the verified answer isD, as it correctly uses thestrftimefunction to convert a timestamp to Unix time in Qlik Replicate1.
