Oracle Solaris 11 Advanced System Administration
Question No: 31
Your company requires all nonglobal zones to have a limit on the number of processes. The policy is designed to prevent runaway processes from impacting the global zone and other nonglobal zones. To set a limit on processes, you set the following controls:
You must now enable system logging for the zone.max-processes resource control to record when the limit is exceeded. Which command enables system logging for a resource
Explanation: Global Actions on Resource Control Values
Global actions apply to resource control values for every resource control on the system. You can use the rctladm command to perform the following actions:
Display the global state of active system resource controls
Set global logging actions
Question No: 32
Your colleague is administering the company’s Automated Install server and is using a custom manifest. You now plan to replace the default AI manifest with the custom manifest.
Which installadm subcommand must you use to replace the default AI manifest?
Answer: B Explanation: Explain:
If you want to change the content of a manifest or script that has already been added to an install service, use the installadm update-manifest command. Criteria, default status, and manifest_or_script_name are not changed as a result of the update.
# installadm update-manifest -n s11-x86
-f ./newregion1.xml -m region1
The create-manifest and update-manifest subcommands validate XML manifest files before
adding them to the install service. AI syntactically validates the AI manifests at client installation time.
Note – If an invalid manifest is provided to a client, the automated installation aborts. To investigate the cause of the validation failure, see the /system/volatile/install_log on the client.
Question No: 33
You and an associate named Frank administer a Solaris server. Frank will be responsible for monitoring system resource usage, so you set up a project entry for his account.
Consider the following commands and output:
Which is Frank’s default project?
Question No: 34
You created a virtual network of three zones. One network hosts a web server.
Another hosts an application server used by the web server. The third zone host a video streaming application.
You already configured a flow to prioritize the video traffic over the web server traffic. You now need to continuously monitor the flow.
Which tool must you use to gather the flow data?
the system activity reporter (SAR)
the flowstat command
the kstat utility
Explanation: Gathering Statistics About Network Traffic on Flows
Flow statistics help you evaluate packet traffic on any defined flows on the system. To obtain flow information, you use the flowstat command.
* Display statistics about incoming and outgoing packets on all flows.
This command provides a static display of traffic information on all configured flows.
Not A: In computing, sar (System Activity Report) is a Solaris-derived system monitor command used to report on various system loads, including CPU activity, memory/paging, device load, network.
Question No: 35
Which network component is the default target for IPMP probe-based Failure detection?
the default router
any nongateway system on the same subnet
any group interface with a test address
the first responder to the in.mpathd broadcast request
Explanation: How to Manually Specify Target Systems for Probe-Based Failure Detection
Add a route to a particular host to be used as a target in probe-based failure detection.
$ route -p add -host destination-IP gateway-IP -static
where destination-IP and gateway-IP are IPv4 addresses of the host to be used as a target. For example, you would type the following to specify the target system 192.168.10.137, which is on the same subnet as the interfaces in IPMP group itops0:
$ route -p add -host 192.168.10.137 192.168.10.137 -static
This new route will be automatically configured every time the system is restarted. If you want to define only a temporary route to a target system for probe-based failure detection, then do not use the -p option.
Add routes to additional hosts on the network to be used as target systems.
Question No: 36
You created a role. The role should be able to change the configuration of a zone. How will you assign that privilege to the role?
Modify the zone using the admin resource, set the user property to the role and the auths property to manage.
Assign to the role the zone Management Rights Profile.
Assign to the role the solaris.zones.* authorization.
Assign to the role the zone Security Rights Profile.
Explanation: The Zone Management profile grants the power to manage all of the non- global zones on the system to a user.
Question No: 37
What is true about crash dump configuration?
The minfree value can be to protect a percentage of available disk space.
The default size of the dump device is configurable.
You can use one ZFS volume for both swap and dump.
You can set quota on a ZFS dump device.
When set on the dump device, the minfree value sets the total size of the dump device to be a percentage of the total size of the root pool.
Explanation: See % below.
coredump parameter: -m mink | minm | min%
Create a minfree file in the current savecore directory indicating that savecore should maintain at least the specified amount of free space in the file system where the savecore directory is located. The min argument can be one of the following:
A positive integer suffixed with the unit k specifying kilobytes.
A positive integer suffixed with the unit m specifying megabytes.
A % symbol, indicating that the minfree value should be computed as the specified percentage of the total current size of the file system containing the savecore directory.
The savecore command will consult the minfree file, if present, prior to writing the dump files. If the size of these files would decrease the amount of free disk space below the minfree threshold, no dump files are written and an error message is logged. The administrator should immediately clean up the savecore directory to provide adequate free space, and re-execute the savecore command manually. The administrator can also specify an alternate directory on the savecore command-line.
Not C: Separate ZFS volumes must be used for the swap area and dump devices.
Question No: 38
Which command reports the scheduling class a process falls under?
Question No: 39
Your company decides to store its software packages in one repository. The new repository will include five publishers. How can you configure your pkg clients such that each package is updated from the publisher originally used to install it?
Configure it such that the preferred publisher has the highest rank.
Configure it such that each publisher is added with the -search-first option.
Configure it such that the top tanked publisher is sticky.
Configure it such that all publishers are sticky.
Configure it such that the bottom-ranked publisher is sticky.
Explanation: set-publisher -sticky
With -sticky, specify that updates to packages that were installed from this publisher must also come from this publisher. This is the default behavior.
Question No: 40
Consider the following commands and output on the local server:
Also, consider the following route table entry on a remote system: 192.168.2.0 192.168.1.200 UG 1 1
You must configure a virtual switch to connect over net0 to the remote system. Select two
commands that complete the configuration.
ipadm set-ifprop -p forwarding=on net0
ipadn set-prop -p forwarding=on vnic2
ipacim set-prop -p forwarding=on ipv4
ipadm set-prop -p routing=on net0
routeadm -ue ipv4-forwarding
routeadm -ue ipv4-routing
