Question 43

Which command should you choose to display the current parameters for the FSS scheduler?

A. dispadmin - c FSS

B. prionctl -c FSS

C. dispadmin -c FSS -g

D. priocntl -c FSS -g

Correct Answer:C
The dispadmin command displays or changes process scheduler parameters while the system is running.
-c class
Specifies the class whose parameters are to be displayed or changed. Valid class values are: RT for the real-time class, TS for the time-sharing class, IA for the inter-active class, FSS for the fair-share class, and FX for the fixed-priority class. The time-sharing and inter- active classes share the same scheduler, so changes to the scheduling parameters of one will change those of the other.
-g
Gets the parameters for the specified class and writes them to the standard output.

Question 44

You have a ZFS file system named /dbase/oral and you want to guarantee that 10 GB of storage space is available to that dataset for all data, snapshots, and clones.
Which option would you choose?

A. zfs set refreservation=10g dbase/oral

B. zfs set quota=10g dbase/oral

C. zfs set refquota=10g dbase/oral

D. zfs set reservation=10g dbase/oral

Correct Answer:D
A ZFS reservation is an allocation of disk space from the pool that is guaranteed to be available to a dataset. As such, you cannot reserve disk space for a dataset if that space is not currently available in the pool. The total amount of all outstanding, unconsumed reservations cannot exceed the amount of unused disk space in the pool. ZFS reservations can be set and displayed by using the zfs set and zfs get commands. For example:
# zfs set reservation=5G tank/home/bill
# zfs get reservation tank/home/bill NAME PROPERTY VALUE SOURCE
tank/home/bill reservation 5G local

Question 45

Which two are true about accounts, groups, and roles in the Solaris user database?

A. All Solaris user accounts must have a unique UID number.

B. A Solaris account name may be any alphanumeric string, and can have a maximum length of 8 characters.

C. Account UID numbers 0-09 are system-reserved.

D. The GID for an account determines the default group ownership of new files created by that account.

E. The groups that an account is a member of are determined by the entries in the/etc/group file.

Correct Answer:AB
A: Solaris uses a UID (User ID) to identify each user account. The UID is a unique number assigned to each user. It is usually assigned by the operating system when the account is created.
B: In Solaris the account name can include any alphanumeric string (and . _ -). The maximum length is 8 characters.

Question 46

You want the system to generate an email notification each time one of the services has changed its state. Which option would send an email message to the system administrator whenever a service changes to the maintenance state?

A. Use the setsc command in ALOM to enable the mail alerts to be sent to a specified email address whenever the fault management facility detects a service change to the maintenance state.

B. Make an entry in the /etc/syslog.conf file to instruct syslogd to send an email alert when it receives a message from the SMF facility that a service has changed to the maintenance state.

C. Use the svccfg setnotify command to create a notification and send an email when a service enters the maintenance state.

D. Use the scvadm command to enable the notification servic

E. Set the –g maintenance option on the netnotify service to send an email when a service enters the maintenance state.

Correct Answer:C
This procedure causes the system to generate an email notification each time one of the services or a selected service has a change in state. You can choose to use either SMTP or SNMP. Normally, you would only select SNMP if you already have SNMP configured for some other reason.
By default, SNMP traps are sent on maintenance transitions. If you use SNMP for monitoring, you can configure additional traps for other state transitions.
1. Become an administrator or assume a role that includes the Service Management rights profile.
2. Set notification parameters.
Example:
The following command creates a notification that sends email when transactions go into the maintenance state
# /usr/sbin/svccfg setnotify -g maintenance mailto:sysadmins@example.com

Question 47

User jack, whose account is configured to use the korn shell, logs in and examines the value of his PATH environment variable:
1Z0-821 dumps exhibit
What will happen, and why?

A. He will get a "file not found" error, because the current directory is not in his seaech path.

B. He will get a "file not found" error, because his home directory is not in his search path.

C. The useradd script will execute, because jack is in the same directory that the script is located in.

D. The command /user/sbin/useradd will execute, because it is the last match in the search path.

E. The command /user/sbin/useradd will execute, because it is the first match in the search path.

Correct Answer:D

Question 48

Which five statements describe options available for installing the Oracle Solaris 11operating system using the installation media?

A. You can perform a text or LiveCD installation locally or over the network.

B. The text Installer does not install the GNOME deskto

C. The GNOME desktop package must he added after you have installed the operating system.

D. The LiveCD Installation cannot be used to install multiple instances of Oracle Solaris.

E. The LiveCD installer cannot be used if you need to preserve a specific Solaris Volume Table of Contents (VTOC) slice in your current operating system.

F. The LiveCD Installer is for x86 platforms only.

G. The GUI installer cannot be used to upgrade your operating system from Solaris 10.

H. If you are installing Oracle Solaris 11 on an x86-based system that will have more than one operating system installed in it, you cannot partition your disk during the installation process.

I. The LiveCD installer can be used for SPARC or x86 platforms.

Correct Answer:ABDFH
A: If the network is setup to perform automated installations, you can perform a text installation over the network by setting up an install service on the network and selecting a text installation when the client system boots.
B: After a fresh install of Solaris 11 express, only the console mode is activated. To add Gnome, simply do :
$ sudo pkg install slim_install
This will install additional packages that are not installed by default. D: The text installer advantages over the GUI installer include:
* In addition to modifying partitions, the text installer enables you to create and modify VTOC slices within the Solaris partition.
F: How do I upgrade my Solaris 10 or lower systems to Solaris 11?
Unfortunately, you CAN'T. There is no direct upgrade installer or other tool that will allow you to upgrade from earlier releases of Solaris to Solaris 11. This is primarily due to the vast changes in the packaging mechanism in Solaris 10.
