What is a drawback of the local database method of securing device access that can be solved by using AAA with centralized servers?

  • There is no ability to provide accountability.
  • It is very susceptible to brute-force attacks because there is no username.
  • The passwords can only be stored in plain text in the running configuration.
  • User accounts must be configured locally on each device, which is an unscalable authentication solution.
    Answers Explanation & Hints:

    The local database method of securing device access utilizes usernames and passwords that are configured locally on the router. This allows administrators to keep track of who logged in to the device and when. The passwords can also be encrypted in the configuration. However, the account information must be configured on each device where that account should have access, making this solution very difficult to scale.
