Q71. - (Topic 2)
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?
A. boot cdrom -smount -f nfs backup_server:/rpool/snaps /rmtzpool create rpool c0t0d0s0cat /mnt/rpool.1202 | zfs receive -Fdu rpoolzpool set bootfs=rpool/ROOT/solaris rpoolRecreate swap and dump devices.Reinstall the bootblock on c0t0d0.
B. boot cdrom -smount -f nfs backup_server:/rpool/snaps /mntzpool create rpool c0t0d0s0zfs create -o mountpoint=/ rpool/ROOTcat /mnt/rpool.1011 | zfs receive -Fdu rpoolzpool set bootfs=rpool/ROOT/solaris rpoolRecreate swap and dump devices.Reinstall the bootblock on c0t0d0.
C. boot cdrom -smount -F nfs backup_server:/rpool/snaps /mntcat /mnt/rpool.1011 | zfs receive -Fdu rpoolzpool set bootfs=rpool/ROOT/solaris rpool c0t0d0s0Reinstall the bootblock on c0t0d0s0
D. boot cdrom -smount -f nfs backup_server:/rpool/snaps /rmtzpool create rpool c0t0d0s0zfs receive -Fdu /mnt/rpool.1011zpool set bootfs=rpool/ROOT/solaris rpoolReinstall the bootblock on c0t0d0.
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.
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.
Mount the remote snapshot dataset.
# mount -F nfs remote-system:/rpool/snaps /mnt
Recreate the root pool.
# zpool create -f -o failmode=continue -R /a -m legacy -o cachefile=/etc/zfs/zpool.cache rpool c1t0d0s0
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.
Set the bootfs property on the root pool BE.
# zpool set bootfs=rpool/ROOT/osolBE rpool
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
Q72. - (Topic 2)
You have been asked to terminate a process that appears to be hung and will not terminate. The process table is shown below:
root 15163 15156 0 12:51:15 pts/3 0:00 hungscript
What command will terminate the process?
A. kill -9 15163
B. kill -1 15163
C. kill -15 15163
D. kill -2 15163
Here we should use SIGTERM to terminate the process.
Note: When no signal is included in the kill command-line syntax,the default signal that is used is –15 (SIGKILL). Using the –9 signal (SIGTERM) with the kill command ensures that the process terminates promptly. However,the –9 signal should not be used to kill certain processes,such as a database process,or an LDAP server process. The result is that data might be lost.
Tip - When using the kill command to stop a process,first try using the command by itself,without including a signal option. Wait a few minutes to see if the process terminates before using the kill command with the -9 signal.
Q73. - (Topic 2)
You are troubleshooting the Oracle Solaris11 Automated Installer (AI),which is not connecting with the IPS software repository.
Which three steps will help determine the cause of DNS name resolution failure?
A. Verify the contents of /etc/resolve.conf.
B. Run netstat -nr to verify the routing to the DNS server.
C. Ping the IP address of the IPS server to verify connectivity.
D. On the installation server,verify that the menu.1st file for the client points to a valid boot arc hive.
E. Run df -k to verify that the boot directory containing the boot archive is loopback mounted under /etc/netboot.
F. Run the command /sbin/dhcpinfo DNSserv to ensure that the DHCP server providing the DNS server information.
(A) Check whether DNS is configured on your client by verifying that a non-empty /etc/resolv.conf file exists.
(F) If /etc/resolv.conf does not exist or is empty,check that your DHCP server is providing DNS server information to the client: # /sbin/dhcpinfo DNSserv If this command returns nothing,the DHCP server is not set up to provide DNS server information to the client. Contact your DHCP administrator to correct this problem.
(B) If an /etc/resolv.conf file exists and is properly configured,check for the following possible problems and contact your system administrator for resolution:
** The DNS server might not be resolving your IPS repository server name. ** No default route to reach the DNS server exists.

View the Exhibit and review the zpool and ZFS configuration information from your system.
Identify the correct procedure for breaking the /prod_data mirror,removing c4t0d0 and c4t2d0,and making the data on c4t0d0and c4t2d0 accessible under the dev_data mount point.
A. zpool split pool1 pool2 c4t0d0 c4t2d0zpool import pool2zfs set mountpoint = /dev_data pool2/prod_data
B. zpool detach pool1 pool2zpool attach pool2zfs set mountpoint=/dev_data pool2/prod_data
C. zpool split pool1/prod_data -n pool2/dev_datazfs set mountpoint = /dev_data pool2/prod_data
D. zpool split pool1 pool2 c4t0d0 c4t2d0zpool import pool2
In this Solaris release,you can use the.zpool split.command to split a mirrored storage pool,which detaches a disk or disks in the original mirrored pool to create another identical pool. After the split operation,import the new pool.
Q75. - (Topic 2)
You are creating a non-global zone on your system.
Which option assigns a zpool to a non-global zone,and gives the zone administrator permission to create zfs file system in that zpool?
A. While creating the non-global zone,make the following entry: add deviceset match=/dev/rdsk/c4t0d0endBoot the zone and log in the zone as root. Create the zpool: zpool create pool2 c4t0d0In the non-global zone,root can now create ZFS file system in the pool2 zpool
B. In the global zone,create the zpool: global# zpool create pool2 c4t1d0While creating the no-global zone,make the following entry: add datasetset name=pool2endadd fsset dir=pool1set special=pool1settype=zfspool1endBoot the zone,log in the zone as root,and create the zfs file system in the pool2 zpool.
C. In the global zone,create the zpool:global#zpool create pool2 c4t1d0While creating the global zone,make the following entry: add datasetset name=pool2endBoot the zone,log in to the zone as root and create the zfs file systems in the pool2 zpool.
D. In the global zone,create the zpool and the ZFS file systems that you want to use in the non-global zone: global#zpool create pool2 c4t1d0global#zfs create pool2/dataWhile creating the non-global zone,make the following entry for each ZFS file system that you want to make available in the zone: add fsset dir=/dataset special=pool2/dataset type=zfsend
E. Create the zpool in the global zone: global#zpool create pool2 c4t1d0Boot the non-global zone,log in to the zone as root,and issue this command to delegate ZFS permissions to root: non-global zone# zfs allow root create,destroy,mount pool2Log in to the non-global zone create ZFS file systems in the pool2 zpool.
You can add a ZFS file system to a non-global zone by using the zonecfg command's add fs subcommand.
In the following example,a ZFS file system is added to a non-global zone by a global zone administrator from the global zone:
# zonecfg -z zion zonecfg:zion> add fs zonecfg:zion:fs> set type=zfs zonecfg:zion:fs> set special=tank/zone/zion zonecfg:zion:fs> set dir=/export/shared zonecfg:zion:fs> end

Q80. - (Topic 1)
You want the system to generate an email notification each time one of the services has changed its state. Which option would send an email message to the system administrator whenever a service changes to the maintenance state?
A. Use the setsc command in ALOM to enable the mail alerts to be sent to a specified email address whenever the fault management facility detects a service change to the maintenance state.
B. Make an entry in the /etc/syslog.conf file to instruct syslogd to send an email alert when it receives a message from the SMF facility that a service has changed to the maintenance state.
C. Use the svccfg setnotify command to create a notification and send an email when a service enters the maintenance state.
D. Use the scvadm command to enable the notification service. Set the –g maintenance option on the netnotify service to send an email when a service enters the maintenance state.
This procedure causes the system to generate an email notification each time one of the services or a selected service has a change in state. You can choose to use either SMTP or SNMP. Normally,you would only select SNMP if you already have SNMP configured for some other reason.
By default,SNMP traps are sent on maintenance transitions. If you use SNMP for monitoring,you can configure additional traps for other state transitions.
Become an administrator or assume a role that includes the Service Management rights profile.
Set notification parameters.
Example: The following command creates a notification that sends email when transactions go into the maintenance state
# /usr/sbin/svccfg setnotify -g maintenance mailto:email@example.com
