A process is required for a telecoms company to work cases supplied via a daily Excel file. Although the file will only contain around 1000 rows, the average case time is such that the workload is far too big for one machine to complete in a day, so the solution has been designed with multiple machines in mind. One machine will load the work queue while the others wait, then once the queue is ready all machines will work it together.
The requirements state that the input file is machine generated, has a known format, is generally clean but may contain exceptions - rows with an empty cell, partial phone numbers, or accounts that don't exist.
What should the solution do to combat this problem?

• A. The solution should apply a filter to the Excel file to hide any row with empty cells and only load the complete rows.
• B. The solution read the file and then loop through the resulting collection and discard any row with either missing, incomplete or invalid data. Then the 'clean' collection should then be loaded into the queue.
• C. The solution should read the file and load the queue without validating the data. The data validation should be the first step in working a queue item, with invalid cases marked as exceptions.
• D. The solution should open the file and delete any row with either missing, incomplete or invalid data.
  Then the 'clean' file should be read and the resulting collection added to the queue.
• E. The solution should validate the data and check that the accounts exist in the target applications beforehand, so that only clean cases are loaded into the queue.

VivaBank have an account closure process that can take up to three days to close an account. All requests within the bank's core system to close an account take place overnight during batch processing. There are two scenarios:

The timings relate to the expected automation time.
All requests will arrive in a Blue Prism work queue from multiple channels using either web services or other Blue Prism processes.
The following detail from the Functional Requirement Questionnaire must be considered:
* Cases must be processed on the same day if they come in between 08:00 and 22:00 Monday to Friday
* Exception cases are to be emailed to the manual team during processing as and when they occur.
* It is expected that up to 200 cases can be expected per day.
The Blue Prism solution consists of four processes and four Blue Prism Work Queues.

Cases come into the Account Closures Work Queue and are processed by the Account Closure process which determines if they are "Nil Balance" or "Balance to Transfer" scenarios. Before adding the case to the relevant work queue, a check is made to see if an identical key has been added to the work queue today. If so the case is not added.
The Transfer Balance process work its queue and, for each successfully processed case, adds case to the Close Account queue.
The Close Account process works its queue and, for each successfully processed case, adds a case to the Confirm Closure queue with the case deferred to 08:00 the next day.
The Confirm Closure process completes the sequence by confirming that the account is finally closed.
A scheduler has been created to start all four processes at 08:00. Each process shall be configured to finish accordingly:

Please select from the statements below the ones you consider to be correct. (Choose two.)

• A. There should be a separate work queue for each channel feeding the process.
• B. Exception cases should not be distributed whilst the processes are running and instead should be distributed when each process has completed.
• C. As an alternative the solution could use just one queue instead of four.
• D. The Confirm Closure process should work until 22:00.
• E. All processes should be merged into one process to optimize licenses.
