The books you mentioned are based on vSphere 5.0 and vSphere Replication has been introduced with vSphere 5.1. What VMkernel traffic is used for is:
- Management
- vMotion
- Fault Tolerance
- vSphere Replication
- Storage networking (e.g, iSCSI)
Note that for storage networking there's no explicit option you need to check/enable, i.e. leave all options unchecked.
