   A FreeBSD system has a SCSI disk that is not responding. The administrator wants to check if the disk is still present on the SCSI bus and possibly rescan the bus to re-detect it. Which command sequence is most appropriate?

   • ARun `camcontrol devlist` to check the device list, then `camcontrol rescan all` to rescan the bus.
   • BRun `atacontrol list` to check the device list, then `atacontrol reinit` to rescan.
   • CRun `kldstat` to check the device list, then `kldunload` and `kldload` the driver.
   • DRun `pciconf -l` to check the device list, then `kldload` to reload the driver.

   A company standardizes on FreeBSD for its servers but is evaluating OpenBSD for a new security-focused appliance. The appliance requires a specific network driver that is available as a kernel module on FreeBSD. The administrator needs to determine if the same driver can be loaded on OpenBSD. What is the most accurate assessment?

   • AThe driver may need to be recompiled for OpenBSD, and the loading command will be `modload` instead of `kldload`.
   • BOpenBSD does not support loadable kernel modules, so the driver must be compiled into the kernel.
   • CThe driver must be loaded with `kldload` on OpenBSD as well.
   • DThe driver will work as-is because both are BSD systems.

   A system administrator manages both FreeBSD and OpenBSD servers. On the FreeBSD server, they use `kldload` to load a network driver module. On the OpenBSD server, they need to load a similar driver module at runtime. What is the correct approach on OpenBSD?

   • ARebuild the kernel with the driver compiled in.
   • BUse `camcontrol load` to load the module.
   • CUse `modload` to load the module at runtime.
   • DUse `kldload` as it is the standard across all BSDs.
