15. A network administrator establishes a connection to a switch via SSH. What characteristic uniquely describes the SSH connection?

  • out-of-band access to a switch through the use of a virtual terminal with password authentication
  • remote access to the switch through the use of a telephone dialup connection
  • on-site access to a switch through the use of a directly connected PC and a console cable

  • HTTP

25. A small company has only one router as the exit point to its ISP. Which solution could be adopted to maintain connectivity if the router itself, or its connection to the ISP, fails?

  • Activate another router interface that is connected to the ISP, so the traffic can flow through it.
  • Have a second router that is connected to another ISP.
  • Purchase a second least-cost link from another ISP to connect to this router.
  • Add more interfaces to the router that is connected to the internal network.
