A datalink can best be described as______.
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.

A user brian is configured to use the bash shell. His home directory is /export/home/brian, and contains a .profile and a .bashrc file.
In the -profile, there are these lines:
genius =ritchie
export genius
In the .bashrc us this line:
genius=kernighan
In /etc/profile are these lines:
genius=thompson
export genius
When brian logs in and asks for the value of genius, what will he find, and why?
On localSYS, your SPARC based server, you back up the root file system with recursive snapshots of the root pool. The snapshots are stored on a remote NTS file system.
This information describes the remote system where the snapshots are stored:
Remote system name: backupSYS
File system whore the snapshots are stored: /backups/localSYS
Mounted file system on localSYS: /rpool/snaps
Most recent backup name: rpool-1202
Disk c0t0d0 has failed in your root pool and has been replaced. The disk has already been part< and labeled and now you need to restore the root file system. Which procedure would you follow to restore the ZFS root file system on localSYS?
How to Recreate a ZFS Root Pool and Restore Root Pool Snapshots
In this scenario, assume the following conditions:
* ZFS root pool cannot be recovered
* ZFS root pool snapshots are stored on a remote system and are shared over NFS
* The system is booted from an equivalent Solaris release to the root pool version so that the Solaris release and the pool version match. Otherwise, you will need to add the -o version=version-number property option and value when you recreate the root pool in step 4 below.
All steps below are performed on the local system.
1.
Boot from CD/DVD or the network.
On a SPARC based system, select one of the following boot methods:
ok boot net -s
ok boot cdrom -s
If you don't use -s option, you'll need to exit the installation program.
2.
Mount the remote snapshot dataset.
For example:
# mount -F nfs remote-system:/rpool/snaps /mnt
3.
Recreate the root pool.
For example:
# zpool create -f -o failmode=continue -R /a -m legacy -o cachefile=/etc/zfs/zpool.cache rpool c1t0d0s0
4.
Restore the root pool snapshots.
This step might take some time. For example:
# cat /mnt/rpool.0311 | zfs receive -Fdu rpool
Using the -u option means that the restored archive is not mounted when the zfs receive operation completes.
5.
Set the bootfs property on the root pool BE.
For example:
# zpool set bootfs=rpool/ROOT/osolBE rpool
6.
Install the boot blocks on the new disk.
On a SPARC based system:
# installboot -F zfs /usr/platform/`uname -i`/lib/fs/zfs/bootblk /dev/rdsk/c1t0d0s0
Your mentor suggests using the dladm rename-link command to rename the network datalinks.
What are the two advantages of following this advice?
Note: dladm rename-link [-R root-dir] link new-link
Rename link to new-link. This is used to give a link a meaningful name, or to associate existing link configuration such as link properties of a removed device with a new device.
You need to install the gzip software package on your system. Which command would you use to find the software package in the configured repository?
Use the pkg search command to search for packages whose data matches the specified pattern.
Like the pkg contents command, the pkg search command examines the contents of packages. While the pkg contents command returns the contents, the pkg search command returns the names of packages that match the query.
