Q111. - (Topic 1)
zone1 is a non-global zone that has been configured and installed.
zone1 was taken down for maintenance,and the following command was run:
zoneadm -z zone1 mark incomplete
The following information is displayed when listing the zones on your system:
Which task needs to be performed before you can boot zone1?
A. The zone needs to be installed.
B. The zone needs to be brought to the ready state.
C. The zone needs to be uninstalled and reinstalled.
D. The zone needs to be brought to the complete state.
Answer: C
Explanation:
If administrative changes on the system have rendered a zone unusable or inconsistent,it is
possible to change the state of an installed zone to incomplete.
Marking a zone incomplete is irreversible. The only action that can be taken on a zone
marked incomplete is to uninstall the zone and return it to the configured state.
Q112. - (Topic 2)
The current ZFS configuration on your server is:
pool1 124K 3.91G 32K /pool1
pool1/data 31K 3.91G 31K /data
You need to create a new file system named /data2. /data2 will be a copy of the /data file system.
You need to conserve disk space on this server whenever possible.
Which option should you choose to create /data2,which will be a read writeable copy of the /data file system,while minimizing the amount of total disk space used in pool1?
A. zfs set mountpoint=/data2 compression=on pool1/data2
B. zfs snapshot pool1/data@nowzfs set mountpoint=/data2,comptession=on pool1/data@now
C. zfs create snapshot pool1/data@nowzfs send pool1/data@now | zfs recv pool1/data2
D. zfs create snapshot pool1/data@nowzfs clone -o mountpoint=/data2 pool1/data@now pool1/data2
E. zfs snapshot pool1/data@nowzfs clone -o mountpoint=/data2 -ocompression=on pool1/data@now pool1/data2
F. zfs snapshot pool1/data@nowzfs clone -o mountpoint=/data2 pool1/data@now pool1/data2
Answer: E Explanation:
zfs snapshot [-r] [-o property=value] ... filesystem@snapname|volume@snapname
Creates a snapshot with the given name. All previous modifications by successful system
calls to the file system are part of the snapshot
zfs clone [-p] [-o property=value] ... snapshot filesystem|volume
Creates a clone of the given snapshot.
Note:
Because snapshots are fast and low overhead,they can be used extensively without great
concern for system performance or disk use .
With ZFS you can not only create snapshot but create a clone of a snapshot.
A clone is a writable volume or file system whose initial contents are the same as the
dataset from which it was created. As with snapshots,creating a clone is nearly
instantaneous,and initially consumes no additional disk space. In addition,you can
snapshot a clone.
A clone is a writable volume or file system whose initial contents are the same as the
original dataset. As with snapshots,creating a clone is nearly instantaneous,and initially
consumes no additional space.
Clones can only be created from a snapshot. When a snapshot is cloned,it creates an
implicit dependency between the parent and child.
Q113. - (Topic 1)
Your users are experiencing delay issues while using their main application that requires connections to remote hosts. You run the command uptime and get the flowing output:
1:07am up 346 day(s),12:03,4 users,load average: 0.02,0.02,0.01
Which command will be useful in your next step of troubleshooting?
A. ipadm
B. traceroute
C. dladm
D. snoop
E. arp
Answer: B
Explanation:
Test the remote connection with traceroute.
The Internet is a large and complex aggregation of network hardware,con-nected together by gateways. Tracking the route one's packets follow (or finding the miscreant gateway that's discarding your packets) can be difficult. traceroute utilizes the IP protocol `time to live' field and attempts to elicit an ICMP TIME_EXCEEDED response from each gateway along the path to some host.
This program attempts to trace the route an IP packet would follow to some internet host by launching UDP probe packets with a small ttl (time to live) then listening for an ICMP "time exceeded" reply from a gateway.
Q114. - (Topic 2)
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 desktop. The GNOME desktop package must he added after you have installed the operating system.
C. The LiveCD Installation cannot be used to install multiple instances of Oracle Solaris.
D. 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.
E. The LiveCD Installer is for x86 platforms only.
F. The GUI installer cannot be used to upgrade your operating system from Solaris 10.
G. 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.
H. The LiveCD installer can be used for SPARC or x86 platforms.
Answer: A,B,D,F,H
Explanation:
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.
Q115. - (Topic 1)
You are planning group names for a new system. You decide to use a numbering convention that includes the year and month the project began,to form the group number and name for work associated with that project.
So,for example,a project targeted to begin in January,2013 would have the number (name):
201301(Pr20l301)
What are the two problems with your plan?
A. Group names may not contain a numeric character
B. Group names may be no longer than 7 characters.
C. Group numbers should not be larger than 60000.
D. Group names should be all lowercase.
Answer: C,D
Explanation:
C: The Group ID (GID) field contains the group's numerical ID. GIDs can be assigned whole numbers between 100 and 60000.
D: Group names contain only lowercase characters and numbers.

Q117. - (Topic 1)
Which network protocol provides connectionless,packet-oriented communication between applications?
A. TCP
B. UDP
C. IP
D. ICMP
E. NFS
F. IPSec
Answer: B
Explanation:
The User Datagram Protocol (UDP) is one of the core members of the Internet Protocol Suite,the set of network protocols used for the Internet. With UDP,computer applications can send messages,in this case referred to as datagrams,to other hosts on an Internet Protocol (IP) network without requiring prior communications to set up special transmission channels or data paths. Compared to TCP,UDP is a simpler message-based connectionless protocol.

The COMSTAR framework provides support for the iSCSI protocol.
Select three options that correctly describe the COMSTAR framework.
A. iSCSI devices can be used as dump devices.
B. SCSI commands are carried over IP networks and enable you to mount disk devices from across the network onto your local system.
C. Large amounts of data can be transferred over an IP network with very little network degradation.
D. COMSTAR allows you to convert any Solaris11 host into a SCSI target device that can be accessed over a storage network.
E. One IP port can handle multiple ISCSI target devices.
Answer: B,D,E
Explanation:
B: By carrying SCSI commands over IP networks,the iSCSI protocol enables you to access block devices from across the network as if they were connected to the local system. COMSTAR provides an easier way to manage these iSCSI target devices.
D: Common Multiprotocol SCSI TARget,or COMSTAR,a software framework that enables you to convert any Oracle Solaris 11 host into a SCSI target device that can be accessed over a storage network by initiator hosts.
E: One IP port can handle multiple iSCSI target devices.
