Correct Answer: A, DBefore migrating to a 2-node switched cluster using Broadcom BES-53248 switches in an existing 2-node switchless AFF A220 cluster, two key conditions must be met. Firstly, all cluster logical interfaces (LIFs) must be in the up state and on their home ports in order to ensure that the network is correctly configured and functioning properly. Secondly, the existing 2-node switchless configuration must be properly set up and functioning to ensure a smooth and error-free transition to a switched environment. These prerequisites ensure operational stability and seamless integration during the migration process.
