Selected Answer: A
Selective LUN Mapping permite que los LUNs sean accesibles solo a través de las LIFs del nodo que posee el LUN, reduciendo el número de caminos innecesarios y mejorando la eficiencia del acceso. En tu escenario: Cada nodo tiene 4 LIFs. Cada host accede a los LUNs por 2 LIFs por nodo. SLM asegura que los hosts vean solo los caminos relevantes a los LUNs, evitando rutas redundantes y mejorando el rendimiento.
