I have CA salesperson license - when to get broker's license?

[Andrew Smith]

I obtained my California Real Estate Salesperson License in June 2017. At that time, my understanding was that the license was valid for 2 years, and then I would need to take another test to obtain the California Broker's License. But while researching this subject a few minutes ago, it looks like the license may actually be valid for 4 years, not 2 as I had thought?

I have not been working as a broker since June 2017, but am probably going to accept an offer to work as a junior broker at a reputable commercial brokerage firm in the very near future.

My questions:

1) Is my California Real Estate Salesperson License valid for 2 years or 4 years?

2) If it is only valid for 2 years, do I need to take the California Broker's test by June 2017 in order to work as a junior broker? Or can I just pay a fee and renew my Salesperson license? What other steps do I need to take in order be properly licensed after the 2 year mark passes in June?
