Oracle Solaris 11 Installation and Configuration Essentials
Question No: 31
What is the relevance of the quot;-cquot; argument in the output below?
the location of thecache directory used by NFS cache
the location ofthe cache directory used during an interrupted download process
the location of theclassdirectory containing various IPS class files needed by Java
the location of the Images containing the MD5 checksum information
the location ofall configured clients and their Install criteria
Answer: B Explanation: pkgrecv
– Image Packaging System content retrieval utility Options include:
The path to a directory that will be used to cache downloaded content. If this directory is not supplied, the client automatically selects a cache directory. In the case where a download is interrupted, and a cache directory was automatically chosen, use this option to resume the download. See the “Environment Variables” section below for details about how to set the location used for temporary data storage.

Which service must be enabled in order to create an iSCSI LUN?
Explanation: How to Enable the STMF Service
COMSTAR uses SMF to store its current, persistent configuration, such as logical unit mapping, host group definitions, and target group definitions. When the service is enabled during boot or when using the svcadm command, it clears any stale configuration data inside the kernel framework, and then reloads the configuration from the SMF repository into the driver.
The COMSTAR target mode framework runs as the stmf service. By default, the service is disabled. You must enable the service to use COMSTAR functionality. You can identify the service with the svcs command. If you have not rebooted the server since installing the group/feature/storage-server package, the service might not be enabled correctly.
*You can set up and configure a COMSTAR Internet SCSI (iSCSI) target and make it available over the network. The iSCSI features can work over a normal Internet connection (such as Ethernet) using the standard iSCSI protocol. The iSCSI protocol also provides
naming and discovery services, authentication services using CHAP and RADIUS, and centralized management through iSNS.

Question No: 33
You are implementing three workloads, one in each of three zones. Which five factors should you consider when configuring networking?
Are VLANs in use
The quantity of physical NICs in the system.
The network bandwidth needs of the workloads.
Which layer 4 protocol family is in use: TCP or UDP?
The range ofIP addresses that each zone can use.
The amount ofprocessing capacity needed to handle network interrupts for each zone.
Answer: A,B,C,E,F Explanation:
*Modern computing environments have to provide a flexible response to the varying workloads that are generated by different applications on a system. A workload is an aggregation of all processes of an application or group of applications. If resource management features are not used, the Oracle Solaris operating system responds to workload demands by adapting to new application requests dynamically. This default response generally means that all activity on the system is given equal access to resources.
Question No: 34
A zone fails to boot, and zoneadm produces the following message:
Which two approaches might resolve the problem and enable the zone to boot?
Change the network link, that will be used by that zone.
Use quot;dladm disable net0quot; in the global zone to bring the NIC net0down.
Convert the zone to use shared-IP networking.
Usequot;dladm rename-linknet0net9quot; in the global zone.
Usequot;netconfig disable net0quot;in the global zone.
Explanation: C:When you assign a network to a global zone, you must define the mode of the network, either Shared IP or Exclusive IP:
In Shared IP mode, the network interface is used by more than one zone. You define the network interface when you you assign the global zone to the network.
In Exclusive IP mode, the network interface is dedicated to the zone. An exclusive network must be declared for the global zone when you assign network to the global zone. Then you configure the IP configuration for the non-global zone.
Not B: There is no command dladm disableto disable a network interface. Not D: There is no command netconfig disable to disable a network interface.
Question No: 35
When upgrading to Oracle Solaris 11 from Oracle Solaris 10, the Live Upgrade utilities are
enhanced to automatically use js2ai and convert jumpstart rules to AI profiles and criteria
not available because there is no upgrade method from Oracle Solaris 10 to Oracle Solaris 11
available in a separate SVR4 package that you have to install onto Oracle Solaris 10 first
only available to you if you have a support agreement in place with Oracle
Explanation: TheJumpStart Migration Utility (js2ai)is used to convert Oracle Solaris 10 JumpStart rules and profiles to a format that is compatible with AI manifest entries.
*There are no upgrade methods or tools available to transition from Oracle Solaris 10 to Oracle Solaris 11. You cannot use an installer to upgrade from Oracle Solaris 10 to Oracle Solaris 11. You must perform a fresh installation of Oracle Solaris 11.
Question No: 36
With which three link types do the dladm set-linkprop and show-linkprop subcommands work?
Answer: A,B,D Explanation:
*virtual local area networks (VLANs), link aggregations, and IP tunnels can be assigned administratively-chosen names and then configured by referring to those names.
*VNICs are pseudo interfaces that you create on top of datalinks. A VNIC has an automatically generated MAC address. Depending on the network interface in use, you can explicitly assign to a VNIC a MAC address other than the default address, as described in the dladm(1M) man page. You can create as many VNICs over a datalink as you require.
*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 becomeindependent 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.
*The basic link aggregation topology involves a single aggregation that contains a set of physical interfaces. You might use the basic link aggregation in the following situations:
For systems that run an application with distributed heavy traffic, you can dedicate an aggregation to that application#39;s traffic.
For sites with limited IP address space that nevertheless require large amounts of bandwidth, you need only one IP address for a large aggregation of interfaces.
For sites that need to hide the existence of internal interfaces, the IP address of the aggregation hides its interfaces from external applications.

Question No: 38
Which command would result in safely detaching a disk or disks from a mirrored pool to create another identical pool?
zfs split tank1 tank2
zpool create tank mirror clt0d0 c2t0d0
zpool split tank1 tank2
zpool detach tank clt0d0
zpool replace tank clt1d0 c2t0d0
Explanation: Use the zpool split command to split a mirrored storage pool, which detaches a disk or disks in the original mirrored pool to create another identical pool.
Question No: 39
You are performing an initial AI Installation of Oracle Solaris 11. You have not identified a target disk for the root pool and your installation fails. What are the two possible disk based reasons for this failure?
You need to specifythe dump and swap partitions in the AI manifest to perform a successful OracleSolaris11Installation.
The disk does not have an SMI label.
You have not specified a mirrored dataset for the root pool.
Thedisk or slice does not match or meet the recommended size parameters of approximately 13GB.
ZFSrequires thedisk to be partitioned first and the root partition must be active.
Explanation: B: The disk intended for the root pool must have an SMI label. Otherwise, the installation will fail.
D:The default target location for the installation is the first disk found on each client that meets the size requirement. If the size of a disk is greater than or equal to the recommended size, the installer selects that disk as the installation target. If the size of the disk is less than the recommended size, the installer checks the next disk. If no disk is found that meets the size requirement, the automated installation fails for that client.
*If you do not specify a target location on a client for installing the Oracle Solaris OS, AI selects a default target.
not A:lt;swapgt; and lt;dumpgt; – Optional. You can use AI to configure swap and dump during the automated install.
Not C: A mirrored dataset for the root pool is not required.

Assuming that a user called quot;operatorquot; exists on the system and is configured to use a profile shell, what is the impact of the following sequence of commands?
The quot;operatorquot; account willbe able to configure NTP properties.
The quot;operatorquot; account willbeable to restart the NTP service.
The quot;operatorquot; account willnot be able to log in using SSH.
The quot;operatorquot; account willnot be impacted by these changes.
The quot;operatorquot; account willonly beaccessibleusing quot;suquot;
Explanation: The Stop rights profile is the simplest way to create a restricted shell. The authorizations and rights profiles that are assigned in the policy.conf file are not consulted. In the default configuration, the role or user is not assigned the Basic Solaris User rights profile, the Console User rights profile, or the solaris.device.cdrw authorization.
Assign the Desktop Applets rights profile and the Stop rights profile to the user.
# usermod -P quot;Desktop Applets,Stopquot; username
This user does not have the Basic Solaris User rights profile or the Console User rights profile. Therefore, no commands other than the commands in the Desktop Applets rights profile can be run by this user.
*The usermod utility modifies a user#39;s login definition on the system. It changes the definition of the specified login and makes the appropriate login-related system file and file system changes.
usermod [-u uid [-o]] [-g group] [-G group [, group…]]
[-d dir [-m]] [-s shell] [-c comment] [-l new_name] [-f inactive] [-e expire]
[-A authorization [, authorization]]
[-P profile [, profile]] [-R role [, role]] [-K key=value] login
One or more comma-separated rightsprofiles defined in prof_attr.
