Oracle Solaris 11 System Administration Free Practice Test — 30 Questions

Question 1

A system administrator is tasked with diagnosing performance issues on a Solaris 11 server that has been reported to be sluggish. After running the `vmstat` command, they observe high values in the \"r\" (run queue) and \"b\" (blocked) columns, while the \"us\" (user CPU time) and \"sy\" (system CPU time) percentages are relatively low. Based on this output, what is the most likely underlying issue affecting the server\'s performance?

Accepted Answer

The server is experiencing a high number of processes waiting for CPU time, indicating potential CPU contention.

Question 2

During an interactive installation of Oracle Solaris 11, an administrator is prompted to configure the network settings. If the administrator opts for a static IP configuration but mistakenly enters an incorrect subnet mask, what is the most likely outcome of this decision?

Accepted Answer

The system will be unable to communicate with devices outside its local subnet.

Question 3

In a situation where a system administrator is troubleshooting a server that has been experiencing random crashes, they decide to check the kernel messages for any clues. After running the `dmesg` command, they notice several entries indicating hardware errors related to a specific disk.
