1.Yes 2.No Refer - https://docs.microsoft.com/en-us/azure/frontdoor/front-door-caching ,You don’t need to purge the cache assets. Here the issue is that the file size needs to be less than 8MB 3.Yes

By default, Frontdoor supports Brotli for html but Frontdoor doesn't support Brotli for XML, so A is incorrect.

To whom is "inbound" the received file? - Is it file uploaded from the customer browser? - Or is it response received from the backend behind Frontdoor? - Or is it inbound from backend to Front door?

Copilot: Q -> (...) 1. The file MIME type is supported by the service 2. Edge nodes must be purged of all cached assets 3. The compression type is supported I need you to give me a YES/NO answer for each of the above sentences (1-3). Provide a simplified and short explanation for each of your answers. A -> 1. YES - Azure Front Door Service supports file compression for a variety of MIME types, and XML files typically have a MIME type that is supported for compression1. 2. NO - Purging the edge nodes of all cached assets is not necessarily related to the issue of XML files not being compressed. This action is usually taken to clear outdated or corrupted content from the cache1. 3. YES - Brotli compression is supported by Azure Front Door Service, and it can be used to compress files on the fly at the POP servers1.

1.Yes 2. No 3. Yes

This was on the exam (9th August 2023). Went with proposed. Scored 910.

1. No 2. Yes 3. Yes

IMHO, Yes/No answers should be based on the details provided in the question, hence: 1. Yes - application/xml is supported 2. No - if we will purge cache it will still not compress the file 3. Yes - statement is about compression type and Brotli is supported

Was on my exam today (3rd of Jan 2023), went with given answer

Why are the admins not correcting the answers having gone thru the highly voted discussion comments!!!

Yes No Yes

Yes No Yes

https://docs.microsoft.com/en-us/azure/frontdoor/standard-premium/how-to-compression In Azure Front Door, only eligible files are compressed. To be eligible for compression, a file must: Be of a MIME type Be larger than 1 KB Be smaller than 8 MB These profiles support the following compression encodings: gzip (GNU zip) brotli If the request supports more than one compression type, brotli compression takes precedence. I guess the root cause is because xml is 9MB in size. 1. YES : xml = MIME type 2. NO : I don't think purging cache is necessary.. 3. YES - brotli is supported

1. Yes 2. No 3. Yes

1. NO - the file must be of a MIME type to be eligible for compression. application/xml or text/xml are not supported. 2. Yes - size should be in 1- 8MB chunks. ( 9 MB divides into 8MB chunk and 1 MB chunk ) 3. Yes - Brotli Compression method is supported.
