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.

  3. Your home directory is /root.

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

  5. Your UID is 1.

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When you exit the shell,root capabilities are no longer in effect.
