Oracle Solaris 11 Advanced System Administration
Question No: 61
The following command is issued: pkg set-publisher -P publisher2
What is the impact on your system?
makes the specified publisher sticky
makes the specified publisher the highest-ranked publisher
displays information about the specified publisher
moves the specified publisher one step higher in the search order
With -P or -search-first, set the specified publisher first in the search order. When installing new packages, this publisher is searched first. Updates to already installed packages come from the same publisher that originally provided the package as long as that publisher remains sticky. When -P or -search-first is used with -p, only added publishers are placed first in search order.
Question No: 62
You configured IPMP on the system:
Based on this information, select the correct conclusion.
No default route is configured.
in.mpathd cannot identify failed interfaces.
There are no active interfaces in the group.
There are three standby interfaces in the group.
The property transitive-probing is false.
Explanation: Disabled in the MODE column means that all probe-based failure detection is disabled.
You must enable transitive probing to use this failure detection method that does not require test addresses.
display IPMP subsystem status
The ipmpstat command concisely displays information about the IPMP subsystem.
The -t option identifies the probe targets that are associated with each IP interface in an IPMP group.
Target mode displays IPMP probe target information. The following output fields are supported:
The IP interface name associated with the information.
The probe target discovery mode:
Probe targets found by means of the routing table.
Probe targets found by means of multicast ICMP probes.
All probe-based failure detection is disabled.
Failure detection is by means of transitive probing, where the health of the IP interface is determined by probing other active interfaces in the group.
The source address used in outgoing probes. Active interfaces that are being used for data traffic, as well as interfaces that have been explicitly configured with NOFAILOVER test addresses, will have the hostname (or IP address) that is used for sending and receiving the ICMP probes. All other interfaces in the group will display the name of the interface from which the probes are sent. Note that if an active IP interface is configured with both
IPv4 and IPv6 test addresses, probe target information will be displayed separately for each test address.
A space-separated list of probe target hostnames (or IP addresses) for ICMP probes, or target interfaces for transitive probes. The IP targets will be listed in firing order, and, if no probe targets could be found, this field will be empty.
Question No: 63
Resource constraints have been placed on a particular project. Which command would you use to view the constraints that have been placed on that project?
Answer: B Explanation: prctl
get or set the resource controls of running processes, tasks, and projects.
The prctl utility allows the examination and modification of the resource controls associated with an active process, task, or project on the system. It allows access to the basic and privileged limits and the current usage on the specified entity.
not A: ipcs provides information on the ipc facilities for which the calling process has read access.
not D: rctladm
– display or modify global state of system resource controls Not E: prstat – report active process statistics
In the Oracle Solaris operating system, the concept of a per-process resource limit has been extended to the task and project entities.
Question No: 64
Consider the following command: dispadmin -c IA -g -r 1000000
Which statement correctly describes the result?
The quantum will be reported in milliseconds.
The quantum will be output every 1000000 milliseconds.
The quantum will be reported in microseconds.
The quantum will be output every 1000000 microseconds.
Question No: 65
Your company wants to incorporate a legacy script that runs once during the boot cycle as an SMF service. What appropriate setting for the duration attribute in the startd property group for this service?
Answer: A Explanation: Example:
The default service model is contract, but may be modified. For this example, we are going to start the service with svc.startd. As a transient service, it will be started once and not restarted by adding the following lines to the manifest:
lt;property_group name=#39;startd#39; type=#39;framework#39;gt;
lt;propval name=#39;duration#39; type=#39;astring#39; value=#39;transient#39;
svc.startd provides three models of service, which are
Transient services-These are often configuration services, which require no long- running processes to provide service. Common transient services take care of boot-time cleanup or load configuration properties into the kernel. Transient services are also sometimes used to overcome difficulties in conforming to the method requirements for contract or wait services. This is not recommended and should be considered a stopgap measure.
Contract services-These are the standard system daemons. They require processes which run forever once started to provide service. Death of all processes in a contract service is considered a service error, which will cause the service to restart.
Wait services-These services run for the lifetime of the child process, and are restarted when that process exits.
Question No: 66
You are asked to configure your system to save crash dump information. While choosing a directory to save the dump data, you consider protecting a minimum amount of free space. What is the default minimum free space in a crash dump directory?
By default, the minimum free space is 10% of the size of the dump volume.
By default, no minimum free space is set.
By default, the minimum free space is 1 MB.
By default, the space is determined by the amount of swap space.
By default, the space is determined by the amount of memory installed in the system.
Explanation: Dump Parameter: minimum free space
Minimum amount of free space required in the savecoredirectory after
saving crash dump files. If no minimum free space has been configured, the default is one Mbyte.
Question No: 67
You are about to configure resource controls for a nonglobal zone. You want to first examine settings as well as the system limits for those controls.
Which command fetches this information?
Explanation: zonecfg subcommand info:
info zonename | zonepath | autoboot | brand | pool | limitpriv info [resource-type [property-name=property-value]*]
Display information about the current configuration. If resource-type is specified, displays only information about resources of the relevant type. If any property-name value pairs are specified, displays only information about resources meeting the given criteria. In the resource scope, any arguments are ignored, and info displays information about the resource which is currently being added or modified.
Not A: priocntl- process scheduler control
The priocntl() function provides for control over the scheduling of an active light weight process (LWP).
Not C: rctladm- display and/or modify global state of system resource controls.
The rctladm command allows the examination and modification of active resource controls on the running system.
Not D: prctl
– get or set the resource controls of running processes, tasks, and projects
The prctl utility allows the examination and modification of the resource controls associated
with an active process, task, or project on the system. It allows access to the basic and privileged limits on the specified entity.
Question No: 68
You have assigned rights profiles directly to the uses frank and now you want to add another profile. Which command enables you to list profiles directly assigned to frank?
userattr profiles frank
profiles -p frank
useratter -p frank
Explanation: Example: Displaying Information About the System Administrator Rights Profile
Use the profiles command to display information about a specific rights profile. In the following example, information about the System Administrator rights profile is displayed:
$ profiles -p quot;System Administratorquot; info name=System Administrator
desc=Can perform most non-security administrative tasks
profiles=Install Service Management,Audit Review,Extended Accounting Flow Etc.
Question No: 69
You want to configure an anonymous IPMP group. Which method lets you enable this behavior?
Set the config/transitive-probing property to true in the svc:/network/imp:default service.
Use the ipadm set-ifprop command to set the anonymous property to true for the IPMP
Edit the /etc/default./mpathd file and set TRACK_INTERFACES_ONLY_WITH GROUPS=no.
Set the config/anonymous property to true in the svc:/network/ipmp:default service.
Explanation: * /etc/default/mpathd
Contains default values used by the in.mpathd daemon.
By default, in.mpathd limits failure and repair detection to IP interfaces that are configured as
part of a named IPMP group. Setting TRACK_INTERFACES_ONLY_WITH_GROUPS to no enables failure and repair detection on all IP interfaces, even if they are not part of a named IPMP group. IP interfaces that are tracked but not part of a named IPMP group are considered to be part of the “anonymous” IPMP group. In addition to having no name, this IPMP group is
special in that its IP interfaces are not equivalent and thus cannot take over for one another in
the event of an IP interface failure. That is, the anonymous IPMP group can only be used for
failure and repair detection, and provides no high-availability or load-spreading
