QUESTION 25
User brian changes the permissions for db_data this command:
chmod 4755 db_data
What is true?

 db_data now has permissions rwsr-xr-x and can be deleted only by user brian.

 db_data now has permissions rwsr-xr-x and,if executed,will inn with the permissions of user brian.

 db_data now has permissions rwxr-sr-x and can be deleted only by members of the group owning it.

 The permissions for db_data cannot be determined,because the permissions prior to the change have not been specified.

 db_data must be an ordinary file,because special permissions cannot be set on a directory.

Use the chmod command to change permissions for a file or directory. You must be the
owner of a file or directory,or have root access,to change its permissions.
Here we do not know if brian owns db_data.

QUESTION 26
You start to execute a program by using the following command:
~ /bigscript &
You then determine that the process is not behaving as expected, and decide that you need to terminate the process.
Based on the information shown below, what is the process number you should terminate?

 15163

 15156

 15166

 15165

From the output exhibit we can deduce that the shell has id 15156.
It has spawned three subprocesses:
grep: id 15166
ps -aef 15165
The remaining 15163 must be the subshell (see note below).
This is the id of the process which should be terminated.

 The IP address.

 The name service.

 The time zone.

 A default user account.

 The terminal type.

 The root password.

 The host name.

Explanation/Reference:
Explanation:
IP address and name service (such as a DNS server) are provided by the DHCP server.

QUESTION 28
Identify the correct description of an IPS image.

 an ISO image of the Solaris media DVD

 an IPS repository

 a depot location or source where Solaris packages can be installed from

 a location where packages can be installed, for example, your Solaris instance

An image is a location where packages can be installed.
An image can be one of three types:
*Full images are capable of providing a complete system.
*Partial images are linked to a full image (the parent image), but do not provide a complete system on their own.
*User images contain only relocatable packages.

QUESTION 29
Subnets are created by using________.

 subnet

 netmask

 unicast

 broadcast

The process of subnetting involves the separation of the network and subnet portion of an address from the host identifier. This is performed by a bitwise AND operation between the IP address and the (sub)network prefix. The result yields the network address or prefix, and the remainder is the host identifier.
The routing prefix of an address is written in a form identical to that of the address itself. This is called the network mask, or netmask, of the address. For example, a specification of the most-significant 18 bits of an IPv4 address, 11111111.11111111.11000000.00000000, is written as
255.255.192.0.
Reference: Subnetwork

QUESTION 30
To assist in examining and debugging running processes, Solaris 11 has a utility that returns pro arguments and the names and values of environment variables.
What is the name of this utility?

 ppgsz

 pargs

 pmap

 pgrep

Explanation/Reference:
Explanation:
The pargs utility examines a target process or process core file and prints arguments, environment variables and values, or the process auxiliary vector.

QUESTION 31
You need to install the gzip software package on your system. Which command would you use to find the software package in the configured repository?

 pkg search gzip

 pkg info gzip

 pkg contents gzip

 pkginfo gzip

 yum list gzip

Explanation/Reference:
Explanation:
Use the pkg search command to search for packages whose data matches the specified pattern.
Like the pkg contents command, the pkg search command examines the contents of packages. While the pkg contents command returns the contents, the pkg search command returns the names of packages that match the query.

QUESTION 32

QUESTION 33
Choose three options that describe the features associated with a Live Media installation.

 does not allow the root user to log in to the system directly from the console (or any terminal)

 provides a “hands free” installation

 installs the desktop based packages

 can be used to install only x86 platforms

 installs the server-based set of packages only

 allows both automatic and manual configuration of the network

 installs both the server-based and desktop-based package

The graphical installer is officially known as the “Live Media.” This means that Oracle Solaris can be booted into RAM, causing zero impact on your existing operating system.
After it is loaded, you are free to experiment with Oracle Solaris to determine whether it is something you would like to install to your system.
You can download Oracle Solaris 11 Live Media for x86, which is an approximately 800 MB image file, and use a DVD burner to create the disk, or you can use the ISO image directly in a virtual machine or through the Oracle Integrated Lights Out Manager (ILOM) Remote Console.
The Live Media is not intended for long-term use. For example, any changes that you make to the system are lost when the system is shut down. Therefore, the next logical step is to install Oracle Solaris on the system, which the Live Media makes easy by placing an Install Oracle Solaris icon right on the desktop. But before we head down that road, let’s step back a bit and consider the installation options.
Note: The Live Media provides administrators with an opportunity to explore the Oracle Solaris 11 environment without installing it on a system. The system boots off the media directly allowing administrators to start the installer should they choose to install it to a system.

QUESTION 34
You are setting up an automated installer (AI) install server and issue the following command:
installadm create-service -n prod_ai -s /repo/prod_ai.iso
-i 192.168.1.100 -c 5 -d /export/repo
Which four options describe the install server that you have configured?

 The service name is prod_ai.

 DHCP base IP address is 192.168.1.100

 The initial IP address for the install clients will be 192.168.1.100. This IP address is temporary. After the client is booted, it will use IP addresses in the following range: 192.168.1.101-105.

 Five IP addresses are allocated for DHCP clients, starting with 192.168.1.100.

 The Install server will support up to five clients.

 The AI net image ISO file is located in /repo/prod and the net image ISO will be unpacked in /export/repo.

 The AI net image ISO file is located in /repo/repo and is named /repo/prod/_ai.iso.

A: -n <svcname>
Uses this install service name instead of default service name.
B: -i <dhcp_ip_start>
Sets up a new DHCP server. The IP addresses, starting from dhcp_address_start, are set up.
D: -c <count_of_ipaddr>
Sets up a total number of IP addresses in the DHCP table equal to the value of the count_of_ipaddr. The first IP address is the value of dhcp_ip_start that is provided by the -i option.
F: -s <srcimage>
Specifies location of AI ISO image to use for setting up the install service.
<targetdir>
Required: Specifies location to set up net image.

QUESTION 35
A user jack, using a korn shell, requests a directory listing as follows:
jack@solaris:/export/home/jack $ 1s
file filea Filea fileb Fileb filec Filec
Which two statements are correct?

 The pattern [?i]*a will expand to fileaFilea.

 The pattern [fF]*a? will expand to [fF] *a?.

 The pattern [gfe] * will expand to file filea fileb filec.

 The pattern [g-e] * will expand to file filea fileb filec.

 The pattern [fF] [a-zA-z]i*e will expand to file.

A:starting withone singlecharacter,second character must be letter i,any characters,
ending with letter a.
C: starting with letter e, f, or g, followed by anything.

QUESTION 36
You have been tasked with creating a dedicated virtual network between two local zones within a single system. In order to isolate the network traffic from other zones on that system.
To accomplish this, you will create__________.

 An ether stub

 A virtual router

 A virtual switch

 A virtual bridge.

 A virtual network interface

 Nothing because a virtual switch is automatically created then the virtual network interfaces are created.

Etherstubs are pseudo ethernet NICs which are managed by the system administrator. You can create VNICs over etherstubs instead of over physical links. VNICs over an etherstub become independent of the physical NICs in the system. With etherstubs, you can construct a private virtual network that is isolated both from the other virtual networks in the system and from the external network. For example, you want to create a network environment whose access is limited only to your company developers than to the network at large. Etherstubs can be used to create such an environment.
Note: Oracle Solaris 11 introduces a new and powerful network stack architecture which includes:
* Networking virtualization with virtual network interface cards (VNICs) and virtual switching (etherstubs)
* Tight integration with zones
* Network resource management – efficient and easy to manage integrated quality of service (QoS) to enforce bandwidth limit on VNICs and traffic flows

QUESTION 37
You enter dladm show-phys, which provides the following output:

You then enter: ipadm create-ip net3 What is the output?

 ipadm: cannot; create interface net3: Operation failed.

 ipadm: cannot create interface net3: Interface already exists.

 ipadm: cannot create interface net3: IP address object notspecified.

 No_response,The command was successful.

According to the exhibit the interface already exists.
The command ipadm create-ip net3
is supposed to create a new interface net3.

QUESTION 38
Your server has a ZFS storage pool that is configured as follows:

The server has two spate 140-GB disk drives: c3t5d0 c3t6d0
Which command would add redundancy to the pool1 storage pool?

 zpool attach pool1 c3t5d0 c3t6d0

 zpool attach pool1 c3t3d0 c3c5d0; zpoo1 attach pool1 c3t4d0 c3t6d0

 zpool mirror pool1 c3t5d0 c3t6d0

 zpool add pool1 mirror c3t5d0 c3t6d0

 zpool add raidz pool1 c3t5d0 c3t6d0

Explanation/Reference:
Explanation:
You can convert a non-redundant storage pool into a redundant storage pool by using the zpool attach command.
Note: zpool attach [-f] pool device new_device
Attaches new_device to an existing zpool device. The existing device cannot be part of a raidz configuration. If device is not currently part of a mirrored configuration, device automatically transforms into a two-way mirror of device and new_device. If device is part of a two-way mirror, attaching new_device creates a three-way mirror, and so on. In either case, new_device begins to resilver immediately.

QUESTION 39
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?

 You can kill a process only if you are root.

 You can kill only a process that you own.

 You can killthe process only with the pkillcommand.

 You need to kill the process with a stronger kill signal.

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.
Reference: Solaris Common Desktop Environment: User’s Guide,Sending Kill Signals to a Process

QUESTION 40
You have been asked to do an orderly shutdown on a process with a PID of 1234, with the kill command.
Which command is best?

 kill -2 1234

 kill -15 1234

 kill -9 1234

 kill -1 1234

Explanation/Reference:
Explanation:
On POSIX-compliant platforms, SIGTERM is the signal sent to a process to request its termination. The symbolic constant for SIGTERM is defined in the header file signal.h. Symbolic signal names are used because signal numbers can vary across platforms, however on the vast majority of systems, SIGTERM is signal #15.
SIGTERM is the default signal sent to a process by the kill or killall commands. It causes the termination of a process, but unlike the SIGKILL signal, it can be caught and interpreted (or ignored) by the process.
Therefore, SIGTERM is akin to asking a process to terminate nicely, allowing cleanup and closure of files.
For this reason, on many Unix systems during shutdown, init issues SIGTERM to all processes that are not essential to powering off, waits a few seconds, and then issues SIGKILL to forcibly terminate any such processes that remain.

QUESTION 41
You run the command dlstat show-link -r.
Select the two correct statements regarding the information displayed in the INTRS column.

 No value is listed for virtual network interfaces.

 A value of 0 is listed for virtual interfaces and ether stubs.

 The number of Interrupts is listed, which indicates network efficiency.

 A number equal to the number of transmitted Ethernet frames is listed for physical links.

 The number of packets that were interrupted by a collision is listed, which may indicate hardware problems.

In this output, the statistics for interrupt (INTRS) are significant. Low interrupt numbers indicate greater efficiency in performance. If the interrupt numbers are high, then you might need to add more resources to the specific link.
Example:
# dlstat -r -i 1
LINK IPKTS RBYTES INTRS POLLS CH<10 CH10-50 CH>50
