Exam DP-203 topic 2 question 57 discussion

AC is correct, there is no point about deletion in source and might be the case that the data should stay in source too.

I think the C option has impact in data transfer, B are incorrect, D is irrelevant for the question, and A is a complement of the task

C & D The question requested a solution that will reduce data transfer between the two systems . The solution is thesame as how can REUNDANCY or Multiple Copies of the data be avoided during copying. Explanation 1.). Deleting the source files after they are copied will keep track of the where to start the next copy . 2.)Filter by the last modified date of the source files; This also helps to keep track of where to resuming file movement from

AC is correct

A. Specify a file naming pattern for the destination: By specifying a file naming pattern for the destination files in the Azure Data Lake Storage Gen2 account, you can ensure that the files are organized and stored in a structured manner. This can help with data management and subsequent processing. C. Filter by the last modified date of the source files: By filtering the source files based on the last modified date, you can select only the files that have been modified on the current day. This reduces the amount of data transferred and improves the efficiency of the data load process.

should be AC

I will go for AC Why not D? Cause they are not mentionned some cost opitmisation

AD are correct ?

The requirement is to minimize the data transfer. If we delete the files in source then there is no need to filter for daily load. So answer C,D is incorrect. Beside, there is no requirement to for minimizing the cost. To my point of view, AC is correct because, even though filter by the modified date will take long time for lot of files, it won't impact the transfer.

Normally we move the files after being processed, so it has to be D.

Shout it be A &D as the requirement is to minimize the process time. Will option C take longer compared to D?

Either C or D can realize daily incremental load. Not sure why need to setup both of them.

should it be C, D?
