Actual exam question for Oracle's 1Z0-821 exam

Question #: 69
Topic #: 11

Identify three differences between the shutdown and init commands.

AOnly shutdown broadcasts a final shutdown warning to all logged-in users.

Binit does not terminate all services normally. The shutdown command performs a cleaner shutdown of all services.

CThe shutdown command can only bring the system to the single-user milestone. The init command must be used to shut the system down to run level 0.

DOnly shutdown sends a shutdown message to any systems that are mounting resources from the system that is being shut down.

EThe shutdown command will shut the system down and turn off power; init will only shut the system down.

Suggested Answer: D, E

n Oracle Solaris 11, you can use the deduplication (dedup) property to remove redundant data from your ZFS file systems. If a file system has the dedup property enabled, duplicate data blocks are removed synchronously. The result is that only unique data is stored, and common components are shared between files.

Hah, imagine if init was like 'Alright, I'm out. Figure it out yourselves!' That would be a mess.

But init is needed to shut the system down to run level 0, right?

Yes, that's true. Shutdown also sends a message to systems mounting resources.

I think the main difference is that shutdown broadcasts a final warning to all users.

I'm not sure about the single-user milestone thing, but the power-off option with shutdown is pretty neat. init just quits, how boring.

The shutdown command seems to have more features than init, like broadcasting warnings and shutting down mounters. I like the cleaner shutdown of services too.
