LinkedIn Connections cost

Summary:

Hello, Does anyone know whether there is a cost associated with the implementation/use of LinkedIn Connections? Also, can we use LinkedIn Connections independently from LinkedIn Apply (i.e. not implement LinkedIn Apply and only use Connections)?

Content (required):

Trying to understand what LinkedIn functionality is available without added cost of implementation or use from a candidate's perspective not a recruiter and whether the 2 options of LinkedIn Apply and Connections must be implemented together or whether one can be used without the other. Thank you in advance!
