CompTIA Network+ (N10-007) — Question 474

Which of the following provides redundancy on a file server to ensure the server is still connected to a LAN even in the event of a port failure on a switch?

Answer options

Correct answer: A

Explanation

NIC teaming combines multiple network interface cards to provide redundancy, ensuring that if one port fails, the server remains connected. The other options do not address this specific issue; a load balancer distributes traffic but doesn't provide redundancy for a single server's connection, a RAID array protects data but is unrelated to network connectivity, and PDUs are power distribution units that manage electrical supply, not network connections.
