Explanation:
Redundant network switches protect against network and switch failures and improve network performance.
Requirement: Requires redundant network connections.
1. Distribute redundant network connections across multiple switches.
2. Connect switches to links with sufficient inter-switch bandwidth.
Incorrect Answers:
B, D: The minimum network configuration is a single-point-of-failure configuration. A network interface failure, control module failure, or network or switch failure causes the member and any volumes with data to go offline until you correct the problem. If it is the only member in the group, the group becomes inaccessible from the network.
To increase performance and availability, Dell recommends that you expand the minimum network configuration
