• Question 41:

  Identify the correct description of an IPS image.

  A. An ISO image of the Solaris media DVD
  B. An IPS repository
  C. A depot location or source where Solaris packages can be installed from
  D. A location where packages can be installed, for example, your Solaris instance
  D. A location where packages can be installed, for example, your Solaris instance

  ---

  An image is a location where packages can be installed. An image can be one of three types:

  *

  Full images are capable of providing a complete system.

  *

  Partial images are linked to a full image (the parent image), but do not provide a complete system on their own.

  *

  User images contain only relocatable packages.

• Question 42:

  Which four can the SMF notification framework be configured to monitor and report?

  A. all service transition states
  B. service dependencies that have stopped or faulted
  C. service configuration modifications
  D. legacy services that have not started
  E. services that have been disabled
  F. service fault management events
  G. processes that have been killed
  A. all service transition states
  E. services that have been disabled
  F. service fault management events
  G. processes that have been killed

  ---

  Note 1: State Transition Sets are defined as:

  to

  Set of all transitions that have as the final state of the transition.

  form-

  Set of all transitions that have as the initial state of the transition.

  Set of all transitions that have as the initial state of the transitional.

  Set of all transitions. (A)

  Valid values of state are maintenance, offline (G), disabled (E), online and degraded. An example of a transitions set definition: maintenance, from-online, to-degraded.

  F: In this context, events is a comma separated list of SMF state transition sets or a comma separated list of FMA (Fault Management Architecture) event classes. events cannot have a mix of SMF state transition sets and FMA event classes.

  For convenience, the tags problem- {diagnosed, updated, repaired, resolved} describe the lifecycle of a problem diagnosed by the FMA subsystem - from initial diagnosis to interim updates and finally problem closure.

  Note 2:

  SMF allows notification by using SNMP or SMTP of state transitions. It publishes Information Events for state transitions which are consumed by notification daemons like snmp-notify(1M) and smtp-notify(1M). SMF state transitions of disabled

  services do not generate notifications unless the final state for the transition is disabled and there exist notification parameters for that transition. Notification is not be generated for transitions that have the same initial and final state.

• Question 43:

  In order to display the IP addresses of network interfaces, what command would you use?

  A. dladm
  B. ipconfig
  C. sves
  D. ipadm
  E. ipaddr
  D. ipadm

  ---

  'ipadm show-addr' displays all the configured addresses on the system. Example:

  # ipadm show-addr ADDROBJ TYPE STATE ADDR lo0/v4 static ok 127.0.0.1/8 lo0/v6 static ok ::1/128

• Question 44:

  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
  E. zfs snapshot pool1/data@nowzfs clone -o mountpoint=/data2 -ocompression=on pool1/data@now pool1/data2

  ---

  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.

• Question 45:

  Review the boot environments displayed on your system:

  

  Which option describes the solaris-1 BE?

  A. It is active on the next reboot.
  B. It is active now.
  C. It is inactive.
  D. It is unbootable.
  E. It is active now and on reboot.
  F. It has been removed and will no longer be available after the next reboot.
  E. It is active now and on reboot.

  ---

  In the below output, NR (now running) means the BE is active now and will be the active BE on reboot.

  Example:

  Display your existing BE information.

  # beadm list

  BE Active Mountpoint Space Policy Created

  solaris NR / 12.24G static 2011-10-04 09:42

• Question 46:

  You are asked to determine user jack's default login directory. Which command would provide you with useful information?

  A. cat /etc/passwd | grep jack
  B. cat /etc/group | grep jack
  C. cat /etc/shadow | grep jack
  D. cat /etc/default/passwd | grep jack
  A. cat /etc/passwd | grep jack

  ---

  The /etc/passwd contains one entry per line for each user (or user account) of the system. All fields are separated by a colon (:) symbol. Total seven fields as follows.

  1.

  Username: It is used when user logs in. It should be between 1 and 32 characters in length.

  2.

  Password: An x character indicates that encrypted password is stored in /etc/shadow file.

  3.

  User ID (UID): Each user must be assigned a user ID (UID). UID 0 (zero) is reserved for root and UIDs 1-99 are reserved for other predefined accounts. Further UID 100-999 are reserved by system for administrative and system accounts/ groups.

  4.

  Group ID (GID): The primary group ID (stored in /etc/group file)

  5.

  User ID Info: The comment field. It allow you to add extra information about the users such as user's full name, phone number etc. This field use by finger command.

  6.

  Home directory: The absolute path to the directory the user will be in when they log in. If this directory does not exists then users directory becomes /

  7.

  Command/shell: The absolute path of a command or shell (/bin/bash). Typically, this is a shell. Please note that it does not have to be a shell.

• Question 47:

  A. NWAM will be used to configure the network interface.
  B. The network/physical service is offline.
  C. You cannot log in from the console as root. You must first log in as a user and then su to root account.
  D. The root user can log in from the console login.
  E. You will be prompted to configure the network interface after the initial login.
  B. The network/physical service is offline.
  D. The root user can log in from the console login.

• Question 48:

  Select the five tasks that need to be performed on the Automated Installer (AI) install server before setting up the client.

  A. Create a local IPS repository on the AI Install server and start the repository server service, the publisher origin to the repository file.
  B. Set up a IP address on the AI install server.
  C. The DHCP server must be enabled on the install server and must provide the DHCP service for the clients.
  D. DHCP must be available on the network for the Install server and the clients, but the install server does not need to be the DHCP server.
  E. Download the AI boot image. The image must be the same version as the Oracle Solaris OS that you plan to install on the client.
  F. Download the text install image into the IPS repository.
  G. Install the AI installation tools.
  H. Create the AI install service. Specify the path to the AI network boot image ISO file and the path where the AI net image ISO file should be unpacked.
  I. Create the AI install service. Specify the path to the AI network boot image ISO file and the path to the IPS repository.
  B. Set up a IP address on the AI install server.
  D. DHCP must be available on the network for the Install server and the clients, but the install server does not need to be the DHCP server.
  F. Download the text install image into the IPS repository.
  G. Install the AI installation tools.
  I. Create the AI install service. Specify the path to the AI network boot image ISO file and the path to the IPS repository.

  ---

  B: Configure the AI install server to use a static IP address and default route.

  D: The create-service command can set up DHCP on the AI install server. If you want to set up a separate DHCP server or configure an existing DHCP server for use with AI. The DHCP server must be able to provide DNS information to the

  systems to be installed.

  E: An automated installation of a client over the network consists of the following high-level steps:

  1.

  The client system boots over the network and gets its network configuration and the location of the install server from the DHCP server.

  2.

  The install server provides a boot image to the client.

  3.

  Characteristics of the client determine which installation instructions and which system configuration instructions are used to install the client.

  4.

  The Oracle Solaris 11 OS is installed on the client, pulling packages from the package repository specified by the installation instructions in the AI install service.

  G: Install the AI tool set.

  Use the installadm create-service command to create an AI install service. Give the service a meaningful name, and specify the path where you want the service created. Specify the source of the network boot image (net image) package or

  ISO file.

  installadm create-service [-n svcname]

  [-s FMRI_or_ISO] [-d imagepath]

  -d imagepath

  The imagepath is the location of the new install service. The install-image/solaris-auto- install package is installed to this location, or the specified ISO file is expanded at this location.

• Question 49:

  You are going to use the- Automated installer (AI) to install a non global zone named zone1. You have created a custom manifest for the non-global zone and named it zone1manifest Which command will you use to add this custom manifest to the s11-sparc install service and associate this custom manifest with the non-global zone?

  A. installadm create-profile -n s11-sparc -f /tmp/zone1manifest.xml - c
  B. installadm create-manifest -n s11-sparc -f /tmp/zone1manifest.xml -m
  C. installadm create-client -n s11-sparc -f /tmp/zone1manifest.xml -m zone1manifest -c zonename= "zone1"
  D. installadm create-service - n s11-sparc -f /tmp/zone1manifest.xml -m zone1manifest - c zonename="zone1"
  B. installadm create-manifest -n s11-sparc -f /tmp/zone1manifest.xml -m

  ---

  installadm add-manifest

  Associates manifests with a specific install service, thus making the manifests available on the network, independently from creating a service. When publishing a non-default manifest, it is required to associate criteria either via criteria entered on the command line (-c) or via a criteria XML file (-C).
