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

Answer: C

Explanation: 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.

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

Answer: D,E
Explanation: 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 thathe can use DTrace to examine kennel datastructures.
B. All that’s required istoassume the “root” role.
C. By using dtrace_procand dtrace_user privileges he can examine his own code, but not the kernel.
D. By addingipc_dac_read and ipc_dac_write privileges to the zone.
E. Changethe zone’s file-mac-profile fromstrict tonone to enable the use of DTrace within thezone.

Answer: C

Explanation: How to Use DTracein a Non-global Zone
global# zonecfg -z my-zone
zonecfg:my-zone> set limitpriv=”default,dtrace_proc,dtrace_user”
zonecfg:my-zone> exit
Note –
Depending on your requirements, you can add either privilege, or both privileges.
Log in to the zone.
global# zlogin my-zone
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.

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. zpoolcreate tank mirror c2t0d0 c2t1d0 log mirrorc2t5d0 c2t8d0
C. zpool c2t0d0 c2t1d0 cachec2t5d0 c2t8d0mirror
D. zpool create tank mirror c2t0d0 c2t1d0 cachec2t5d0 c2t8d0
E. zpool create tankraidz2c2t0d0 c2t1d0 c2t5d0 c2t8d0

Answer: D

Explanation: 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 status tank
pool: tank
state: ONLINE
scrub: none requested
config:
NAME STATE READ WRITE CKSUM
tank ONLINE 0 0 0
mirror-0 ONLINE 0 0 0
c2t0d0 ONLINE 0 0 0
c2t1d0 ONLINE 0 0 0
c2t3d0 ONLINE 0 0 0
cache
c2t5d0 ONLINE 0 0 0
c2t8d0 ONLINE 0 0 0
errors: No known data errors
# 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

QUESTION 2
Which statement describes the default network set upby an Oracle template script?

A. The container is isolated from the network.
B. Avethdevice is added to libvirt’svirbr0bridge.
C. Amacvlandevice enables DHCP from the host’s network.
D. A private interface is routed to Open vSwitch.

Answer: B

Explanation:
By default, the lxc-oracle template script sets up networking by setting up a veth bridge. In this mode, a
container obtains its IP address from the dnsmasq server that libvirtd runs on the private virtual bridge network
(virbr0) between the container and the host. The host allows a container to connect to the rest of the network by
using NAT rules in iptables, but these rules do not allow incoming connections to the container. Both the host
and other containers on the veth bridge have network access to the container via the bridge.

B. The client can use either a local database in the form of a Berkeley DB formatted file in/etc/iscsior a distributed database in the form of Internet StorageNaming Service (iSNS) as its database. It is a decision for the System and StorageAdministration team.
C. The client maintains a local database in the form of a directory tree structure in/var/lib/iscsi.
D. The client maintains a local database in the form of a directory tree structure in/etc/iscsi/db.

Answer: A
