In a fresh installation of Oracle Solaris 11, default datalinks are named with a genetic naming convention, and they increment as you add interfaces. What is the default name?
Correct Answer:B
When you install this Oracle Solaris release on a system for the first time, Oracle Solaris automatically provides generic link names for all the system's physical network devices. This name assignment uses the net# naming convention, where the # is the instance number. This instance number increments for each device, for example, net0, net1, net2, and so on.
Note:
Network configuration in Oracle Solaris 11 includes
* Generic datalink name assignment – Generic names are automatically assigned to datalinks using the net0, net1, netN naming convention, depending on the total number of network devices that are on the system
Consider the following commands:
What is displayed when this sequence of commands is executed using the bash shell?
Correct Answer:B
First line (rm file1) deletes/removes file1. Second line captures the text into file2.
The first part of line 3 (cat file1) fails as the file1 does not exist.
The && (AND) operator will ensure that the third line fails. The result of line 3 will be the result of first part of line 3 (cat file1).
Note: cat - concatenate files and print on the standard output
Note #1: A list is a sequence of one or more pipelines separated by one of the operators ‘;’, ‘&’, ‘&&’, or ‘||’, and optionally terminated by one of ‘;’, ‘&’, or a newline.
Of these list operators, ‘&&’ and ‘||’ have equal precedence, followed by ‘;’ and ‘&’, which have equal precedence.
AND and OR lists are sequences of one or more pipelines separated by the control operators ‘&&’ and ‘||’, respectively. AND and OR lists are executed with left associativity.
An AND list has the form command1 && command2
command2 is executed if, and only if, command1 returns an exit status of zero.
An OR list has the form command1 || command2
command2 is executed if, and only if, command1 returns a non-zero exit status.
The return status of AND and OR lists is the exit status of the last command executed in the list.
Note #2 (on exit status): Zero means command executed successfully, if exit status returns non-zero value then your command failed to execute.
This iron is displayed on the desktop of a laptop computer, which is running Oracle Solaris 11.
Which two statements describe the Information conveyed by this Icon?
Correct Answer:BC
B: The Network Status notification icon is only displayed on the desktop if you are using NWAM to automatically configure your network.
C: All online (Wireless)
Indicates all manually enabled connections in the enabled network profile are online and that the required number of connections in the enabled profile group (if such a group exists) are online. The required number is the same as those described for the All online (Wired) status.
Note that at least one online connection is wireless.
User1 is attempting to assist user2 with terminating user2's process 1234. User1 entered the following: kill -9 1234
Why does the process continue to run?
Correct Answer:B
Kill -9
Kill (terminates without cleanup)
Only works if issued by process owner or super user (root) The program cannot respond to this signal; it must terminate
Note: Unix provides security mechanisms to prevent unauthorized users from killing other processes. Essentially, for a process to send a signal to another, the owner of the signaling process must be the same as the owner of the receiving process or be the superuser.
