Which statement is correct about route reflector design?

Selecting the best exit point from the AS is controlled by BGP attributes such as local preference, MED, and AS-path length - not by route reflector placement.

EIGRP unequal cost load balancing is a feature specific to EIGRP and has no relationship to BGP route reflector architecture or placement decisions.

Route reflectors operate purely at the control plane, reflecting BGP routing information between iBGP peers without participating in actual packet forwarding. Placing them on the data path creates unnecessary bottlenecks and single points of failure for traffic. Best practice is to deploy route reflectors on dedicated off-path devices so that a failure does not disrupt both routing information exchange and data forwarding simultaneously.

Finding the closest exit from the AS is a BGP routing policy concept related to hot-potato routing and MED, not a function or benefit of route reflectors.
