Microsoft AZ-204 Exam - Topic 5 Question 12 Discussion

Actual exam question for Microsoft's AZ-204 exam

Question #: 12
Topic #: 5

You are developing an ASP.NET Core website that uses Azure FrontDoor. The website is used to build custom weather data sets for researchers. Data sets are downloaded by users as Comma Separated Value (CSV) files. The data is refreshed every 10 hours.

Specific files must be purged from the FrontDoor cache based upon Response Header values.

You need to purge individual assets from the Front Door cache.

Which type of cache purge should you use?

Asingle path

Bwildcard

Croot domain

Show Suggested Answer

Suggested Answer: A

These formats are supported in the lists of paths to purge:

Single path purge: Purge individual assets by specifying the full path of the asset (without the protocol and domain), with the file extension, for example, /pictures/strasbourg.png;

Wildcard purge: Asterisk (*) may be used as a wildcard. Purge all folders, subfolders, and files under an endpoint with /* in the path or purge all subfolders and files under a specific folder by specifying the folder followed by /*, for example, /pictures/*.

Root domain purge: Purge the root of the endpoint with '/' in the path.

Root domain purge seems too broad for this case.

Wildcard could be useful too, but not for individual assets.

Wait, can you really purge just one file? Sounds too good to be true.

Totally agree, single path makes sense for targeted cache clearing.

I think a single path purge is the way to go for specific files.

I feel like we practiced a similar question, and I might have chosen wildcard then, but that seems more for broader purging, right?

I think using a single path makes sense for purging individual assets, especially since we need to target specific files based on their headers.

I remember we discussed cache purging in our last class, but I'm not entirely sure which option is best for purging specific files.

I’m leaning towards the root domain option, but I’m not confident it would work for individual files. I need to double-check that.

Hmm, I'm a bit unsure about this one. The question mentions that the logging configurations are already in place, so I'll need to focus on identifying the right line of code to add the custom category debug logging.
