A alternativa correta é a letra A: "LSAs são usados para armazenar a topologia completa do segmento de rede em cada roteador". As LSAs (Link State Advertisements) são usadas pelo protocolo OSPF (Open Shortest Path First) para compartilhar informações de topologia entre os roteadores em uma rede. Cada roteador OSPF mantém um banco de dados de LSAs que contém informações sobre os links de rede e os roteadores vizinhos. As LSAs tipo 1 (LSA de roteador) contêm informações sobre os links diretamente conectados ao roteador, enquanto as LSAs tipo 2 (LSA de rede) contêm informações sobre a rede em si. Juntas, essas LSAs permitem que cada roteador OSPF construa uma imagem completa da topologia da rede e calcule as rotas mais curtas para cada destino.
