Select the five tasks that need to be performed on the Automated Installer (AI) install server before setting up the client.
- A. Install the AI installation tools.
- B. 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.
- C. 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.
- D. Set up a IP address on the AI install server.
- E. Download the text install image into the IPS repository.
- F. Create a local IPS repository on the AI Install server and start the repository server service, the publisher origin to the repository file.
- G. 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.
- H. Create the AI install service. Specify the path to the AI network boot image ISO file and the path to the IPS repository.
- I. The DHCP server must be enabled on the install server and must provide the DHCP service for the clients.
Answer: A,D,E,G,H
Explanation:
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.
NEW QUESTION 50
You run the command dlstat show-link -r.
Select the two correct statements regarding the information displayed in the INTRS column.
- A. A value of 0 is listed for virtual interfaces and ether stubs.
- B. The number of Interrupts is listed,which indicates network efficiency.
- C. A number equal to the number of transmitted Ethernet frames is listed for physical links.
- D. No value is listed for virtual network interfaces.
- E. The number of packets that were interrupted by a collision is listed,which may indicate hardware problems.
Answer: B,E
Explanation:
In this output,the statistics for interrupt (INTRS) are significant. Low interrupt numbers indicate greater efficiency in performance. If the interrupt numbers are high,then you might need to add more resources to the specific link.
Example: # dlstat -r -i 1 LINK IPKTS RBYTES INTRS POLLS CH<10 CH10-50 CH>50 e1000g0 101.91K 32.86M 87.56K 14.35K 3.70K 205 5 nxge1 9.61M 14.47G 5.79M 3.82M 379.98K 85.66K 1.64K vnic1 8 336 0 0 0 0 0 e1000g0 0 0 0 0 0 0 0 nxge1 82.13K 123.69M 50.00K 32.13K 3.17K 724 24 vnic1 0 0 0 0 0 0 0

NEW QUESTION 51
You log in to the system as user1, then switch user to root by using the su - command. After entering the correct password, yon enter the following commands:
whoami;who am i;id
Which option correctly represents the output?
- A. Option D
- B. Option C
- C. Option A
- D. Option B

* The whoami utility displays your effective user ID as a name.
Here this would be root.
* who am i
The command who shows who is logged on.
Here this would be:
user1 console Dec 30 20:20
* The id utility displays the user and group names and numeric IDs, of the calling process, to the standard output. If the real and effective IDs are different, both are displayed, otherwise only the real ID is displayed.
Here this would be:
uid=0(root) gid=0(root)
Note:
Each UNIX proces has 3 UIDs associated to it. Superuser privilege is UID=0.
Real UID
--------
This is the UID of the user/process that created THIS process. It can be changed only if the running process has EUID=0.
Effective UID
-------------
This UID is used to evaluate privileges of the process to perform a particular action. EUID can be change either to RUID, or SUID if EUID!=0. If EUID=0, it can be changed to anything.
Saved UID
---------
If the binary image file, that was launched has a Set-UID bit on, SUID will be the UID of the owner of the file.
Otherwise, SUID will be the RUID.
