Hi,
Both the courses have a global recognition but still, SAP wins over CCNA with respect to salary and exposure.

For free SAP courses refer open SAP, write open SAP on google window and you will reach to the platform where the option certification is available.

Hello,
The exact amount would depend on the level of understanding you have of the certification and application, as you do not have experience.The general range lies between 25K to 40k for freshers.

Not now. First, grab a job and go through the real production process. SAP comes with different module and you got to decide which one you prefer later.

Hello,
At the risk of my personal pride, I will confess that based on my analysis of how did you get your start in SAP? It appears that Basis (SAP System Administration) and SAP ABAP Programming are the two specialties which are most frequently entered immediately upon graduating with a Bachelor's degree.
This makes sense if you think about it though. These two disciplines require the least amount of "Business" knowledge. Folks who major in Computer Science or something related will have a base skill set which can be easily adapted to Basis and/or programming in ABAP.
Thanks.
