Question No.101

The core dump configuration in your non global zone is

image

A user is running a process in a non-global zone (testzone) and the process crashes. The process information is:

user126632618017:46:42pts/20:00/usr/bin/bash

When the user#39;s process crashes in testzone, a non-global zone, where will the core dump be saved?

  1. The file will be stored in the non-global zone#39;s directory:

    /var/core/pprocess/core.hash.2663.

  2. The file will be saved in the global zone#39;s directory: /var/core/core.bash.2663.

  3. A core file cannot be generated in a non-global zone because it shares the kernel with the global zone.

  4. The file will be stored in the global zone#39;s directory: /var/core/pprocess/core.bash.2663.

  5. The file will be saved in non-global zone#39;s directory: /var/core/core.bash.2663

Correct Answer: E

Explanation:

The line

init core file pattern: /var/core/core.%f.%p

will be used for the non-global process to determine the destination of the dump file.

Note:

When a process is dumping core, up to three core files can be produced: one in the per-process location, one in the system-wide global location, and, if the process was running in a local (non- global) zone, one in the global location for the zone in which that process was running.

Reference: man coreadm

Question No.102

How should you permanently restrict the non-global zone testzone so that it does not use more than 20 CPU shares while it is running?

  1. While configuring the zone, add this entry: add rct1

    set name = capped.cpu-shares

    add value (priv = privileged, limit = 20, action = none) end exit

  2. While configuring the zone, add this entry: add rct1

    set name= zone.cpu-shares

    add value (priv=privileged, limit=20, action=none) end

    exit

    from command line, enter:

    # dispadmin – d FSS

  3. From the command line enter:

    #prct1 -n zone.cpu-shares – r – v 20 – i zone testzone

  4. From the command line, enter:

#prct1 – n zone.cpu-shares – v 80 – r – i zone global

Correct Answer: C

Explanation:

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.

How to Change the zone.cpu-shares Value in a Zone Dynamically This procedure can be used in the global zone or in a non-global zone.

Be superuser, or have equivalent authorizations.

For more information about roles, see Configuring and Using RBAC (Task Map) in System Administration Guide: Security Services.

Use the prctl command to specify a new value for cpu-shares. # prctl -n zone.cpu-shares -r -v value -i zone zonename idtype is either the zonename or the zoneid. value is the new value.

Note:

project.cpu-shares

Number of CPU shares granted to a project for use with the fair share scheduler Reference: man prtcl

Question No.103

View the Exhibit. The file came from your Automated Installer (AI) install server. The file is

.

image

  1. an AI SC profile for non-global zones

  2. the default AI config file for non-global zones

  3. the default AI manifest for non-global zones

  4. a custom AI manifest

Correct Answer: D

Explanation:

ai_manifest Automated installation manifest file format Synopsis

/usr/share/install/ai.dtd.1

Some customizations have been made, such as the selection of specific locales. Reference:

Oracle Solaris 11 Installation Man Pages

Question No.104

When setting up Automated Installer (AI) clients, an interactive tool can be used to generate a custom system configuration profile. The profile will specify the time zone, data and time, user and root accounts, and name services used for an AI client installation. This interactive tool will prompt you to enter the client information and an SC profile (XML) will be created. Which interactive tool can be used to generate this question configuration?

  1. sys-unconfig

  2. installadm set-criteria

  3. sysconfig create-profile

  4. installadm create-profile

Correct Answer: B

Explanation:

Use the installadm set-criteria command to update the client criteria associated with an AI manifest that you already added to a service using installadm add- manifest.

Use the installadm add-manifest command to add a custom AI manifest to an install service. The value of manifest is a full path and file name with .xml extension. The manifest file contains an AI manifest (installation instructions). The manifest file can also reference or embed an SC manifest (system configuration instructions).

Question No.105

Which three events trigger the automated NWAM configuration? (Choose three.)

  1. a DHCP lease is acquired.

  2. a WLAN card is disconnected.

  3. The DefaultFixed NCP is enabled.

  4. An Ethernet cable is disconnected.

  5. A failed interface card assigned to an IPMP group is replaced.

  6. The dladm create-vnic command is executed to create a virtual network interface.

Correct Answer: ABD

Question No.106

The resource control in your zone is: rcll

name: zone.cpu-shares

value: (pnv=phvJleged,limit=20,aclion=none)

When you boot the zone, this message is displayed:

WARNING: The zone.cpu-shares rctl is set but FSS is not the default scheduling class for this zone. FSS will be used for processes in the zone but to get the full benefit of FSS, it should be the default scheduling class.

Which option will resolve this issue?

  1. in the global zone, run this command to change the process scheduler for the global zone dispadmin -d FSS

  2. in the non-global zone, run this command to change the process scheduler for this specific zone: dispadmin -d FSS

  3. Change the zone resource control to: value: (priv=privileged,limit=20,action=none,default)

  4. Use svccfg to modify the general/scheduler property in the svc:/system/zones: default service: svccfg -s system/zones:default editprop general/scheduler=FSS

Correct Answer: D

Question No.107

For an Oracle Solaris 11 Automated Installation (Al), select the two properties that can be configured using System Configuration profiles (SC profiles). (Choose two.)

  1. IP address of the Al server

  2. passwords for user accounts

  3. target disk slice for installation

  4. NWAM active network configuration profile (NCP)

  5. IP address of the IPS (Image Packaging System) repository

  6. SI_MANIFEST_SCRIPT, which defines the URL of the manifest script

Correct Answer: BF

Question No.108

You are setting up an automated installer (AI) install server and issue the following command:

installadm create-service -n prod_ai -s /repo/prod_ai.iso \ i 192.168.1.100 -c 5 -d /export/repo

Which four options describe the install server that you have configured?

  1. The service name is prod_ai.

  2. DHCP base IP address is 192.168.1.100

  3. The initial IP address for the install clients will be 192.168.1.100. This IP address is temporary. After the client is booted, it will use IP addresses in the following range: 192.168.1.101-105.

  4. Five IP addresses are allocated for DHCP clients, starting with 192.168.1.100.

  5. The Install server will support up to five clients.

  6. The AI net image ISO file is located in /repo/prod and the net image ISO will be unpacked in

    /export/repo.

  7. The AI net image ISO file is located in /repo/repo and is named /repo/prod/_ai.iso.

Correct Answer: ABDF

Explanation:

A: -n lt;svcnamegt;

Uses this install service name instead of default service name.

B: -i lt;dhcp_ip_startgt;

Sets up a new DHCP server. The IP addresses, starting from dhcp_address_start, are set up.

D: -c lt;count_of_ipaddrgt;

Sets up a total number of IP addresses in the DHCP table equal to the value of the count_of_ipaddr. The first IP address is the value of dhcp_ip_start that is provided by the -i option.

F: -s lt;srcimagegt;

Specifies location of AI ISO image to use for setting up the install service. lt;targetdirgt; Required: Specifies location to set up net image.

Reference: man installadm

Question No.109

View the exhibit to inspect the file system configuration on your server.

image

You department#39;s backup policy is to perform a full backup to a remote system disk on Saturday. On each weekday, you are to perform an incremental backup to the same remote system disk.

Each incremental backup will contain only data that has been modified since the previous Saturday backup.

The server file systems must remain available at all times and can never be taken offline.

The backup must not only provide for the recovery of the most recent version of a file, but must also allow recovery of previous versions of a file.

Following your company policy, which two describe the correct procedure to be performed on each weekday for backing up the /data file system to a remote disk named /remote/backup?

  1. Remove the previous daily snapshot. zfs snapshot pool1.data@daily

    zfs send – i pool1/data@sat pool1/data@daily gt; /remote/backup/full

  2. Remove the previous daily snapshot. zfs snapshot pool1.data@daily

    zfs send – i pool1/data#sat pool1/data@daily | zfs recv remote /backup/ `date ` %m%d%#39;

  3. Remove the previous daily snapshot. zfs snapshot pool1.data@daily

    zfs send – i pool1/data@sat pool1/data@daily gt; /remote/backup/daily

  4. Remove the previous daily snapshot.

zfs create – i pool1/data@sat pool1/data@daily zfs send pool1/data@daily | zfs remote/backup

Correct Answer: BC

Explanation:

You can use the zfs send command to send a copy of a snapshot stream and receive the snapshot stream in another pool on the same system or in another pool on a different system that is used to store backup data.

You can send incremental data by using the zfs send -i option. For example:

host1# zfs send -i tank/dana@snap1 tank/dana@snap2 | zfs recv newtank/dana Note that the first argument (snap1) is the earlier snapshot and the second argument (snap2) is the later snapshot. In this case, the newtank/dana file system must already exist for the incremental receive to be successful.

The incremental snap1 source can be specified as the last component of the snapshot name. This shortcut means you only have to specify the name after the @ sign for snap1, which is assumed to be from the same file system as snap2. For example:

host1# zfs send -i snap1 tank/dana@snap2 gt; zfs recv newtank/dana This shortcut syntax is equivalent to the incremental syntax in the preceding example.
