Why would a Page Route Map be defined?

Why would a Page Route Map be defined?

1 . To redirect users to a Service Portal login page

2 . To redirect users to a Service Portal after they login

3 . To specify what Search Sources a Service Portal should use

4 . To automatically redirect users from one page to another

Hi @Samiksha_12 

Again, why are you posting these questions?
If it is to get answers to a test or something like that, then just please don't...

It won't help you in your career if you just know the answers of the questions, but do not know why.

If your intent of these questions is completely different, then please give some more explanation.
