A web server has to be available all the time. It has its own redundant power source and uninterruptible power supply (UPS). Which of the following actions will provide additional fault tolerance?
The correct answer is D. Add a second NIC. To provide additional fault tolerance for a web server beyond power redundancy, network redundancy is essential.

Why each option
To provide additional fault tolerance for a web server beyond power redundancy, network redundancy is essential.
Adding a second DVD drive does not enhance the operational fault tolerance of a web server, as DVD drives are typically not critical for its continuous service delivery.
Adding a second NIC (Network Interface Card) provides network fault tolerance by creating redundancy for the server's network connection. If one NIC fails, the server can still communicate over the network using the other, ensuring continuous availability for web services.
