Ensuring File Server Connectivity with LAN Redundancy

A.

The correct answer is A. NIC teaming.

NIC teaming, also known as network interface card teaming or link aggregation, is a technique used to combine multiple network interface cards (NICs) into a single logical interface. By doing this, NIC teaming provides redundancy and increases the bandwidth available to the file server.

In the event of a port failure on a switch, NIC teaming allows the server to continue to communicate with the LAN by using the remaining functional NICs. The NIC teaming software automatically detects the failed port and redistributes the traffic to the remaining ports, ensuring that the server remains connected to the network.

Load balancers are used to distribute traffic across multiple servers to ensure that no single server becomes overwhelmed. They are not used for redundancy on a file server.

RAID arrays are used to protect against data loss by creating redundant copies of data across multiple hard drives. While RAID can provide some level of redundancy, it does not provide redundancy in the event of a port failure on a switch.

PDUs (power distribution units) are used to distribute power to multiple devices in a data center. They are not used for network redundancy.
