What will happen if the router cannot find a startup configuration during startup?

  1. It will not boot.

  2. It will boot from RAM.

  3. You'll be prompted for a TFTP server.

  4. You'll be prompted to start the setup dialog.

Show answer
Correct Option: D
Explanation:

If the router cannot locate a configuration file (on a new router for example) it will start setup and it will ask if you want to enter the initial configuration dialog, if you answer with No, you'll be taken to the command prompt and you'll be able to configure the router manually. If you answer with Yes, you'll be taken through a list of questions allowing you to configure the router e.g. set a hostname, enable password and enable secret, configure routed and routing protocols and interface addressing. You can also initiate this configuration dialog using the command: setup.

The network on which the application server is located has been experiencing occasional outages that the network team believes may be related to recent routing changes. Network and application teams have been notified to work on their respective issues. Which statement applies to this situation?

  1. Only results from the software package should be tested as the network is designed to accommodate the proposed software platform.

  2. Scheduling will be easy if the network and software teams work independently.

  3. It will be difficult to isolate the problem if two teams are implementing changes independently.

  4. Results from changes will be easier to reconcile and document if each team works in isolation.

Show answer
Correct Option: C
