    You are setting up a local IPS package repository on your Oracle Solaris11 server: solaris.example.com.

    You want to point the existing local IPS publisher to the new local IPS repository located in

    /repo.

    These are the stops that you have followed:

    1. Download and rsync the contents of the Oracle Solaris11 repository ISO image to the

      /repo directory.

    2. Configure the repository server service properties. The svcprop command display,the IPS related properties:

      pkg/inst_root astring/repo pkg/readonly Boolean true

      The 1s command displays the contents of the /repo directory:

      #ls/repo

      Pkg5.repository publisher

      The svcs publisher command shows the svc: /application/pkg/server: default service is online.

      The pkg publisher command shows the svc: /application/pkg/server: default service is online.

      The pkg publisher command still displays: PUBLISHERTYPESTATUSURI

      solarisoriginonlinehttp://pkg.oracle.com/solaris/release/

      Which steps needs to be performed to set the local IPS publisher to the local IPS repository/repo?

      1. Issue the pkgrepo refresh -s command to refresh the repository.

      2. Restart the svc:/application/pkg/server:default service.

      3. pkg set-publisher command to set the new repository location.

      4. Issue the pkgrepo rebuild command to rebuild the repository.

      5. Issue the pkgrepo set command to set the new repository location.

Answer: C Explanation:

Set the Publisher Origin To the File Repository URI

To enable client systems to get packages from your local file repository,you need to reset the origin for the solaris publisher. Execute the following command on each client:

Example:

# pkg set-publisher -G #39;*#39; -M #39;*#39; -g /net/host1/export/repoSolaris11/ solaris

Question No: 154 – (Topic 2)

The line

set noexec_user_stack= l

should be added to the /etc/system file to prevent an executable stack while executing user programs. What is the purpose of this?

  1. help prevent core dumps on program errors

  2. help programs to execute more quickly by keeping to their own memory space

  3. log any messages into the stack log

  4. help make buffer-overflow attacks more difficult

Answer: D Explanation:

How to Disable Programs From Using Executable Stacks Purpose: Prevent executable stack from overflowing.

You must be in the root role.

Edit the /etc/system file,and add the following line: set noexec_user_stack=1

Reboot the system.

# reboot

Question No: 157 – (Topic 2)

You need to set up a local package repository to serve 75 client systems. Multiple clients will being the package repository concurrently and you need to ensure that the local repository performs very well under this heavy load,especially during package intensive operations.

Which option would ensure the best performance of the repository during package- intensive rations by multiple clients?

  1. Set up multipathing on the package repository server to distribute the network load multiple network interfaces.

  2. Deploy a second instance of the package repository server to run as a read writable mirror.

  3. Deploy a second instance of the package repository server to run as a read-only mirror.

  4. Deploy a second instance of the package repository server to run as a clone of the primary repository server.

  5. Deploy a package repository locally on each client.

Answer: A

Question No: 158 – (Topic 2)

You want to deploy Oracle Solaris 11 with the Automated Installer (AI). You need to make sure that your server and network meet the requirements for using AI.

Identify two requirements for using AI.

  1. You should set up DHCP. The DHCP server and AI install server can be the same machine or two different machines.

  2. You can create only one manifest per install service. If you need more than one manifest,you should create multiple install services.

  3. The minimum requirement to operate as an AI install server is 1 GB of memory.

  4. If two client machines have different architectures and need to be installed with the same version of the Oracle Solaris 11 OS,then you should create two AI manifests and a single install service.

Answer: A,D Explanation:

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

Step 1. The client system boots over the network and gets its network configuration and the location of the install server from the DHCP server.

Step 2: The install server provides a boot image to the client. Etc.

D: If two client machines need to be installed with the same version of the Oracle Solaris 11 OS but

need to be installed differently in other ways,then create two AI manifests for the AI install service. The different AI manifests can specify different packages to install or a different slice as

the install target,for example.

Question No: 159 – (Topic 2)

You are logged in to a Solaris 11 system as user jack. You issue the following sequence of commands:

Identify two correct statements.

  1. You have the effective privilege of the account root.

  2. Your GID is 10.

  3. Your home directory is /root.

  4. You are running the shell specified for the account root.

  5. Your UID is 1.

Answer: A,B Explanation:

Oracle Solaris provides predefined rights profiles. These profiles,listed in the

/etc/security/prof_attr,can be assigned by the root role to any account. The root role is assigned all privileges and all authorizations,so can perform all tasks,just as root can when root is a user.

To perform administrative functions,you open a terminal and switch the user to root. In that terminal,you can then perform all administrative functions.

$ su – root

Password: Type root password

#

When you exit the shell,root capabilities are no longer in effect.

Question No: 160 – (Topic 2)
