You are attempting to troubleshoot an event that should have made an entry into the messages log. This event happened about two weeks ago. Which file should you look at
first?

1. A. /var/adm/messages
2. B. /var/adm/messages.0
3. C. /var /adm/messagas.1
4. D. /var/adm/messages.2
5. E. /var/adm/messages.3

Correct Answer: A
The /var/adm/messages is the file to which all the messages printed on the console are logged to by the Operating System. This helps to track back check the console messages to troubleshoot any issues on the system.
Syslog daemon also writes to this /var/adm/messages file.
The /var/adm/messages file monitored and managed by newsyslog and its configuration file is /usr/lib/newsyslog.
This script runs as the roots cron job everyday, checks the /var/adm/messages file and copies/moves it to /var/adm/messages.0, 1, 2, 3, 4, 5, 6, 7. In other words, it does the Log Rotation for the /var/adm/messages.
In an event the /var file system is running out of space, these files needs to checked and can be removed (not the actual /var/adm/messages itself) to free up space on the file system.
However, care has to be taken, if you decide to empty the /var/adm/messages itself for any reason. This process is called Truncation.

View the Exhibit to inspect the boot environment Information displayed within a non global zone on your system.

Which two options describe the solaris-1 boot environment?

1. A. The solaris-1 boot environment is not bootable.
2. B. The solaris-1 boot environment is incomplete.
3. C. The solaris-1 boot environment was created automatically when the non global zone was created.
4. D. The solaris-1 boot environment was created in the non-global zone using the beadm create command.
5. E. The solaris-1 boot environment is associated with a non active global zone boot environment.

Correct Answer: AE
A: The – of the Active Column indicates that this boot environment is inactive, and hence not bootable.
Note: The values for the Active column are as follows: R – Active on reboot.
N – Active now.
NR – Active now and active on reboot. “-” – Inactive.
“!” – Unbootable boot environments in a non-global zone are represented by an exclamation point.

You created an IP address for interface not.3 with the following command, which executed successfully:
ipadm create-addr –T static –a 192.168.0.100/24 net3/v4
You then ran: ipadm show–if
The result indicated that the interface was down.
You then ran:
ipadm delete-addr net3/v4
ipadm create-addr –T static –a 192.168.0.101/24 net3/v4 ipadm show-if
The last command indicated that the interface was up.
Why did it work with the second address specified, but not the first?

1. A. The 192.168.0.100 address is reserved for broadcast messages.
2. B. Another device exists on the network, using the 192.168.0.100 address.
3. C. The network interface card does not support the address 192.168.0.100.
4. D. The address 192.168.0.100 is at a boundary and may not be configured in Oracle Solaris 11.
5. E. 192.168.0.100 is a DHCP address and may not be statically configured in Oracle Solaris 11.

Correct Answer: B
The first IP address is already in use.

You have set up the task.max-lwps resource control on your Solaris 11 system.
Which option describes how to configure the system so that syslogd notifies you when the resources control threshold value for the task.max-lwps resource has been exceeded?

1. A. Use the rctladm command to enable the global action on the task.max-lwpa resource control.
2. B. Modify the /etc/syslog.conf file to activate system logging of all violations of task.max- lwps and then refresh then svc: /system/system-log:default service.
3. C. Activate system logging of all violations of task.max-lwpp in the /etc/rctldm.conf file and then execute the rctladm-u command.
4. D. Use the prct1 command to set the logging of all resource control violations at the time the task.max-lwps resource control is being setup.
5. E. Use the setrct1 command to set the logging of all resource control violations for the task.max-lwps resource control.

Correct Answer: A
rctladm - display and/or modify global state of system resource controls
The following command activates system logging of all violations of task.max-lwps.
# rctladm -e syslog task.max-lwps
