Which three statements are correct about rip version 2?

RIP version 2 (RIPv2) is a distance-vector routing protocol that supports classless routing, allowing for the use of variable-length subnet masking (VLSM). It includes the ability to send routing updates via multicasting to reduce unnecessary load on the network. Additionally, RIPv2 incorporates authentication features to enhance security compared to its predecessor, RIPv1, which does not support these capabilities. Lastly, RIPv2 has a maximum hop count of 15, similar to RIPv1, which limits the size of networks it can effectively manage.
