Question
A network administrator is shipping a Cisco ASA to a remote retail site. The administrator wants to ensure that the device configuration cannot be accessed by someone at the site with physical access and a console cable. Which command must be used to mitigate this risk?
Options
- Aaaa authentication console
- Bconfig-register 0x00000041
- Cno service password-recovery
- Dno service sw-reset-button

Why each option
To prevent unauthorized physical access to the configuration of a Cisco ASA via a console cable and password recovery mechanisms, the `no service password-recovery` command must be used.
`aaa authentication console` configures authentication for the console line but does not prevent someone from using the password recovery process to bypass it if `service password-recovery` is enabled.
`config-register 0x00000041` is a Cisco IOS command (not ASA specific usually in this exact format) used to change the configuration register, often to ignore the startup configuration or boot into ROMMON, which could facilitate password recovery if not explicitly disabled.
The `no service password-recovery` command disables the password recovery mechanism on a Cisco ASA, which typically allows a user with physical access to bypass authentication and reset the configuration. By disabling this, it prevents an unauthorized person with a console cable from gaining access to or altering the device's configuration. This command helps enforce stronger physical security.
`no service sw-reset-button` might be relevant for some devices with a physical reset button, but it is not the standard or primary command on a Cisco ASA to disable console-based password recovery.
