A combinação de ajustes de arquitetura que a empresa deve implementar para alcançar alta disponibilidade são: A. Adicionar a instância NAT a um grupo de dimensionamento automático do EC2 que abrange várias Zonas de Disponibilidade. Atualizar as tabelas de roteamento. B. Criar instâncias adicionais do EC2 que abranjam várias Zonas de Disponibilidade. Adicionar um Balanceador de Carga de Aplicativo para dividir a carga entre elas. Essas duas opções fornecerão redundância e distribuição de carga para garantir alta disponibilidade do sistema.
