The command dladm is used to configure data-link interfaces in Sun Solaris. A configured data-link is represented in the system as interface that can be used for TCP/IP. Each data-link relies on either a single network device or an link aggregation device to send & recieve packets. Network interfaces provide the connection between the system and the network. These interfaces are configured over data links, which in turn correspond to instances of hardware devices in the system. In the current model of the network stack, interfaces and links on the software layer build on the devices in the hardware layer. More specifically, a hardware device instance in the hardware layer has a corresponding link on the data-link layer and a configured interface on the interface layer. This one-to-one relationship among the network device, its data link, and the IP interface is illustrated in the figure that follows. Network Stack Showing Network Devices, Links, and Interfaces:
Question 92
View the Exhibit to inspect the boot environment Information displayed within a non global zone on your system. Which two options describe the solaris-1 boot environment?
Correct Answer: A,E
A: The - of the Active Column indicates that this boot environment is inactive, and hence not bootable. Note: The values for the Active column are as follows: R - Active on reboot. N - Active now. NR - Active now and active on reboot. "-" - Inactive. "!" - Unbootable boot environments in a non-global zone are represented by an exclamation point. http://docs.oracle.com/cd/E23824_01/html/E21801/unbootable.html#scrolltoc
Question 93
Which two options are characteristics of a fast reboot?
Correct Answer: C,D
C: To change the default behavior of the Fast Reboot feature on the SPARC platform, so that a fast reboot is automatically performed when the system reboots, see below. The following example shows how to set the property's value to true on the SPARC platform, so that a fast reboot is initiated by default: # svccfg -s "system/boot-config:default" setprop config/fastreboot_default=true # svcadm refresh svc:/system/boot-config:default D: Fast Reboot implements an in-kernel boot loader that loads the kernel into memory and then switches to that kernel. The firmware and boot loader processes are bypassed, which enables the system to reboot within seconds. The Fast Reboot feature is managed by SMF and implemented through a boot configuration service, svc:/system/boot-config. The boot-config service provides a means for setting or changing the default boot configuration parameters. When the config/fastreboot_default property is set to true, the system performs a fast reboot automatically, without the need to use the reboot -f command. This property's value is set to true on the x86 platform. For task-related information, including how to change the default behavior of Fast Reboot on the SPARC platform, see Accelerating the Reboot Process on an x86 Based System. Note: One new feature, called Fast Reboot, will allow the system to boot up without doing the routine set of hardware checks, a move that can make system boot times up to two- and-a-half times faster, Oracle claimed. This feature can be handy in that an administrator applying a patch or software update across thousands of Solaris deployments can reboot them all the more quickly.
Question 94
Your server has a ZFS storage pool that is configured as follows: The server has two spare 146-GB disk drives: c3t5d0 c3t6d0 You need to add more space to the pool1 storage pool. Which command would add more mirrored storage to the pool1 storage pool?
Correct Answer: C
Question 95
You are installing the Solaris 11 Operation System by using the Text Installer. A panel prompts you to create a root password and a user account. Which four describe your options for completing this panel of the Installation?
Correct Answer: A,B,D,G
Explanation/Reference: Explanation: A: You are not required to create a user account. B: You must create a root password. D: If you create a user account in this panel, you need to provide both the user's password and a root password. In this case, root will be a role assigned to the user. G: If you do not create a user account, you still need to provide a root password. In this case, root will be a regular user.
