Question 77

A user on the system has started a process, but it needs to be terminated.
The process ID was determined as follows:
pgrep userprogram
l5317
The user attempted to terminate the program as follows:
pkill 15317
This command runs without an error message, and the process continues to run.
What is the issue?

Correct Answer: B
Explanation/Reference:
Explanation:
You can use the pgrep and pkill commands to identify and stop command processes that you no longer want to run. These commands are useful when you mistakenly start a process that takes a long time to run.
To terminate a process:
Type pgrep to find out the PID(s) for the process(es).
Type pkill followed by the PID(s).
You can kill any process that you own. Superuser can kill any process in the system except for those processes with process IDs of 0, 1, 2, 3, and 4. Killing these processes most likely will crash the system.

Question 78

You have installed software updates to a new boot environment (BE) and have activated that the booting to the new BE, you notice system errors. You want to boot to the last known good configuration.

How to Activate an Existing Boot Environment beadm activate beName
beName is a variable for the name of the boot environment to be activated.
Note the following specifications.
beadm activate beName activates a boot environment by setting the bootable pool property, bootfs, to the value of the ROOT dataset of the boot environment that is being activated.
beadm activate sets the newly activated boot environment as the default in the menu.lst file.
The newly activated boot environment is now the default on the x86 GRUB menu or SPARC boot menu.

Question 80

Which four can the SMF notification framework be configured to monitor and report?

Correct Answer: A,E,F,G
Note 1: State Transition Sets are defined as:
to<state>
Set of all transitions that have <state> as the final state of the transition.
form-<state>
Set of all transitions that have <state> as the initial state of the transition.
< state>
Set of all transitions that have <state> as the initial state of the transitional.
Set of all transitions. (A)
Valid values of state are maintenance, offline (G), disabled (E), online and degraded. An example of a transitions set definition: maintenance, from-online, to-degraded.
F: In this context, events is a comma separated list of SMF state transition sets or a comma separated list of FMA (Fault Management Architecture) event classes. events cannot have a mix of SMF state transition sets and FMA event classes. For convenience, the tags problem- {diagnosed, updated, repaired, resolved} describe the lifecycle of a problem diagnosed by the FMA subsystem - from initial diagnosis to interim updates and finally problem closure.
Note 2:
SMF allows notification by using SNMP or SMTP of state transitions. It publishes Information Events for state transitions which are consumed by notification daemons like snmp-notify(1M) and smtp-notify(1M). SMF state transitions of disabled services do not generate notifications unless the final state for the transition is disabled and there exist notification parameters for that transition. Notification is not be generated for transitions that have the same initial and final state.
