Exam Description

QUESTION 1
What information would the "beadm list -ds" command output?
A. a list of all Bes
B. a list of the datasets and snapshot information for the active BE
C. a list of the datasets and snapshot information for all Bes
D. a list of the default sets
E. a list of BEs in machine readable format
Correct Answer: C
Explanation
Explanation/Reference:
You can display information about snapshots, boot environments, and datasets that were created by the
beadm command by using the beadm list subcommand. The beadm list command output also displays boot
environments that are created by the pkg command.
The beadm list command syntax is:
Syntax: beadm list [-a | [-ds] [-H] [BeName] The command lists information about the existing boot
environment. To view information for a specific boot environment, replace BeName with a boot environment
name. If a specific boot environment is not specified, the command lists information about all boot
environments. The default is to list boot environments without additional information.
-a Lists all available information about the boot environment. This information includes subordinate datasets
and snapshots.
-d Lists information about all subordinate datasets that belong to the boot environment.
-s Lists information about the snapshots of the boot environment.
-H Prevents listing header information. Each field in the output is separated by a semicolon.
Reference: Oracle Solaris 11 Information Library, Listing Existing Boot Environments and Snapshots
QUESTION 2
What two entries could complete the following command from the directory listing below?
A. inetboot.SUN4U.Solaris_10-1
B. inetboot.SUN4V.Solaris_l0-1
C. nbp.
D. pxegrub.I86PC.Solaris_10-1
E. sllgrub.i86pc
Correct Answer: DE
Explanation
Explanation/Reference:
As per exhibit these are the two files in the netboot directory.
Note:
*Missing argument is:
file=wanbootCGI-URL Specifies the URL of the wanboot-cgi program on the web server * During the
installation, WAN boot refers to the contents of the /etc/netboot hierarchy on the web server for instructions
about how to perform the installation. This directory contains the configuration information, private key, digital
certificate, and certificate authority required for a WAN boot installation. During the installation, the wanboot-cgi
program converts this information into the WAN boot file system. The wanboot-cgi program then transmits the
WAN boot file system to the client.
QUESTION 3
A developer wants to use DTrace in a zone to examine the kernel. What are his options?
A. Modify the zone so that he can use DTrace to examine kennel data structures.
B. All that's required is to assume the "root" role.
C. By using dtrace_proc and dtrace_user privileges he can examine his own code, but not the kernel.
D. By adding ipc_dac_read and ipc_dac_write privileges to the zone.
E. Change the zone's file-mac-profile from strict to none to enable the use of DTrace within the zone.
Correct Answer: C
Explanation
Explanation/Reference:
How to Use DTrace in a Non-global Zone 1. Use the zonecfg limitpriv property to add the dtrace_proc and
dtrace_user privileges.
global# zonecfg -z my-zone zonecfg:my-zone> set limitpriv="default,dtrace_proc,dtrace_user" zonecfg:myzone>
exit Note Depending on your requirements, you can add either privilege, or both privileges.
2. Boot the zone.
3. global# zoneadm -z my-zone boot Log in to the zone.
global# zlogin my-zone 4. Run the DTrace program.
my-zone# dtrace -l Note:
* Oracle Solaris DTrace is a comprehensive, advanced tracing tool for troubleshooting systemic problems in
real time.
* DTrace helps you understand a software system by enabling you to dynamically modify the operating system
kernel and user processes to record additional data that you specify at locations of interest, called probes.

Solaris Zones, Using DTrace in a Non-Global Zone
QUESTION 4
Your system has two disk devices, c2t0d0 and c2t1d0, and two flash devices, c2t5d0 and c2t8d0.
Which command would you to create a storage pool named "tank," which mirrors the disks and adds the two
flash devices as "cache"?
A. zpool create tank mirror c2t0d0 c2t1d0 mirror c2t5d0 c2t8d0
B. zpool create tank mirror c2t0d0 c2t1d0 log mirror c2t5d0 c2t8d0
C. zpool c2t0d0 c2t1d0 cache c2t5d0 c2t8d0 mirror
D. zpool create tank mirror c2t0d0 c2t1d0 cache c2t5d0 c2t8d0
E. zpool create tank raidz2 c2t0d0 c2t1d0 c2t5d0 c2t8d0
Correct Answer: D
Explanation
Explanation/Reference:
Creating a ZFS Storage Pool with Cache Devices You can create a storage pool with cache devices to cache
storage pool data. For example:
# zpool create tank mirror c2t0d0 c2t1d0 c2t3d0 cache c2t5d0 c2t8d0 Note:
* Creating a Basic Storage Pool The following command creates a new pool named tank that consists of the
disks c1t0d0 and c1t1d0:
# zpool create tank c1t0d0 c1t1d0 These whole disks are found in the /dev/dsk directory and are labelled
appropriately by ZFS to contain a single, large slice. Data is dynamically striped across both disks.
* Creating a Mirrored Storage Pool To create a mirrored pool, use the mirror keyword, followed by any number
of storage devices that will comprise the mirror. Multiple mirrors can be specified by repeating the mirror
keyword on the command line. The following command creates a pool with two, two-way mirrors:
# zpool create tank mirror c1d0 c2d0 mirror c3d0 c4d0 Reference: Solaris ZFS Administration Guide, Creating
a ZFS Storage Pool with Cache Devices
QUESTION 5
The "pkg update" command will ______.
A. update all packages that have updates available including the kernel
B. update all packages that have updates available excluding the kernel
C. update only the kernel image
D. update the global zone packages and non-global zone packages
E. update all packages and the kernel, and then automatically reboot the system
Correct Answer: A
Explanation
Explanation/Reference:
Updating all of the packages on your installed system To update all of the packages on your system that have
available updates, use the pkg update command, as follows:
# pkg update Running this command updates packages that you might not otherwise consider updating, for
example, kernel components and other low-level system packages.
QUESTION 6
What three items are true with regard to network planning in a Solaris 11 environment?
A. Hardware and network topology should be planned in advance of installation.
B. Subnetting needs to be considered when implementing IPv6 networks.
C. IPv4 and IPv6 network addressing cannot co-exist on the same server.
D. Solaris 11 enables the use of local files, NIS, DNS, or LDAP for name services.
E. The physical network topology will determine if you need routers, not all networks require routers.
Correct Answer: ACD
Explanation
Explanation/Reference:
The following table lists different tasks for planning the network configuration.
* (A) Identify the hardware requirements of your planned network topology.
Determine the types of equipment that you need for your network site.
*(C) Determine the type of IP addresses to use and obtain registered IP addresses.
Select whether you are deploying a purely IPv4 network, an IPv6 network, or a network that uses both types of
IP addresses. Obtain unique IP addresses to communicate to public networks in the Internet.
* (D) Determine a naming scheme to identify the hosts in the network as well as the name service to use.
Create a list of names to assign to the systems on the network and decide whether to use NIS, LDAP, DNS, or
the network databases in the local /etc directory.
* If necessary, establish administrative subdivisions and design a strategy for subnets.
Decide if your site requires that you divide your network into subnets to service administrative subdivisions *
Determine where to place routers in the network design.
If your network is large enough to require routers, create a network topology that supports them.
* Decide whether to create virtual networks in the overall network configuration scheme.
You might need to create virtual networks within a system to reduce the hardware footprint of your network.
