Jack is working in an organization as an IT specialist. The company’s web server is undergoing a process of security and redundancy enhancement. Hence, the server is now backed up with multiple power supplies and spike protection. Which of the following would strengthen the server in terms of a high uptime?
  1. Upgrading all the switches in the network to Gigabit
  2. Upgrading the outbound NIC to a gigabit card
  3. Installing an additional Router
  4. Installing additional NICs on the server
Explanation
Answer: D - Redundancy refers to the availability of a component to substitute for a failed component. Adding extra NICs can make it fault tolerant in terms of the network connectivity.

Key Takeaway: To increase the uptime of the server, add some more NICs with power backup systems. This ensures that a working NIC can be available at times of NIC failure.
