A small advertising company has a web server that provides critical business service. The company connects to the Internet through a leased line service to an ISP. Which approach best provides cost effective redundancy for the Internet connection?

  • Add a second NIC to the web server.
  • Add another web server to prepare failover support.
  • Add a connection to the Internet via a DSL line to another ISP.
  • Add multiple connections between the switches and the edge router.
    Answers Explanation & Hints:

    With a separate DSL connection to another ISP, the company will have a redundancy solution for the Internet connection, in case the leased line connection fails. The other options provide other aspects of redundancy, but not the Internet connection. The options of adding a second NIC and adding multiple connections between the switches and the edge router will provide redundancy in case one NIC fails or one connection between the switches and the edge router fails. The option of adding another web server provides redundancy if the main web server fails.
