Hi Sanjana,

Mode of recording comes into picture if you are unable perform correlation. If you are not getting any info in one type of recording, then switch to other type of recording.

Regarding architecture, it is always good to know about the architecture. Architecture knoewledge reveals your maturity and confidence level for any tester.

I hope this helps. Let me know if you need any further clarifications.

Thank you,
