The /etc/hosts file can be best described as .

1. A. a local database of host names for rlogin, rsh, and rep
2. B. the configuration file for the host name of the system
3. C. a local database of information for the uname command
4. D. the configuration file for the Domain Name Service (DNS)
5. E. a local database of host names and their associated IP addresses

Correct Answer: E
As your machine gets started, it will need to know the mapping of some hostnames to IP addresses before DNS can be referenced. This mapping is kept in the /etc/hosts file. In the absence of a name server, any network program on your system consults this file to determine the IP address that corresponds to a host name.

You are installing the Solaris 11 Operation System by using the Text Installer. A panel
prompts you to create a root password and a user account.
Which four describe your options for completing this panel of the Installation?

1. A. Creating a user account is optional.
2. B. The root password must be set and cannot be blank.
3. C. The root password can be left blank.
4. D. If you provide a username, that user is assigned the root role.
5. E. If you provide a username, that user is given root privileges.
6. F. If you provide a username, root is an account rather than a role and is set to expire immediately.
7. G. If you do not provide a username, root is an account rather than a role and is set to expire immediately.

Correct Answer: ABDG
A: You are not required to create a user account. B: You must create a root password.
D: If you create a user account in this panel, you need to provide both the user's password and a root password.
In this case, root will be a role assigned to the user.
G: If you do not create a user account, you still need to provide a root password. In this case, root will be a regular user.

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?

1. A. You need to run the pkill command with the process name.
2. B. You need to switch to super user to kill the process.
3. C. You need to run the ps command to get more information.
4. D. You need to run the prstat command to get more information.

Correct Answer: B
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.

Review the ZFS dataset output that is displayed on your system:

Which four correctly describe the output?

1. A. /data/file4 has been added.
2. B. The link /data/file3 has been added.
3. C. /data/file3 has been renamed to /data/file13.
4. D. /data/file4 has been modified and is now larger.
5. E. /data/file1 has been deleted.
6. F. /data/file1 has been modified and is now smaller.
7. G. /data/file5 has been modified.
8. H. /data/file3 (a link) has been removed.

Correct Answer: ACEG
A: + Indicates the file/directory was added in the later dataset
C: R Indicates the file/directory was renamed in the later dataset E: - Indicates the file/directory was removed in the later dataset
G: M Indicates the file/directory was modified in the later dataset
Note: Identifying ZFS Snapshot Differences (zfs diff)
You can determine ZFS snapshot differences by using the zfs diff command.
The following table summarizes the file or directory changes that are identified by the zfs diff command.
File or Directory Change Identifier
* File or directory is modified or file or directory link changed M
* File or directory is present in the older snapshot but not in the newer snapshot
—
* File or directory is present in the newer snapshot but not in the older snapshot
+
* File or directory is renamed R

Identify three differences between the shutdown and init commands.

1. A. Only shutdown broadcasts a final shutdown warning to all logged-in users.
2. B. init does not terminate all services normall
3. C. The shutdown command performs a cleaner shutdown of all services.
4. D. The shutdown command can only bring the system to the single-user mileston
5. E. The init command must be used to shut the system down to run level 0.
6. F. Only shutdown sends a shutdown message to any systems that are mounting resources from the system that is being shut down.
7. G. The shutdown command will shut the system down and turn off power; init will only shut the system down.
