Your server hangs intermittently and you believe it may be due to either faulty hardware or a driver. The support technician has told you to generate a live core dump of all memory pages for further analysis Your dump configuration is:

Dump content: kernel pages

Dump device: /dev/zvol/dsk/rpool/dump (dedicated)

Savecore directory: /var/crash

Savecore enabled: yes

Save compressed: on

You don't have enough space on the current dump device, so you need to store the dump on /dev/zvol/ dsk/pool2/dump

Which option would you select to change the dump location for the next core dump and capture the content of all memory pages as requested by the support technician?

A. dumpadm -d /dev/zvol/dsk/pool2/dump

B. dumpadm -d /dev/zvol/dsk/pool2/dump -c all

C. dumpadm -d /dev/zvol/dsk/pool2/dump -c curproc

D. dumpadm -s /dev/zvol/dsk/pool2/dump -c all

E. dumpadm -s /dev/zvol/dsk/pool2/dump

You are going to create live zones on you server. Disk space is critical on this server so you need to reduce the amount of disk space required for these zones. Much of the data required for each of these zones is identical, so you want to eliminate the duplicate copies of data and store only data that is unique to each zone.

Which two options provide a solution for eliminating the duplicate copies of data that is common between all of these zones?

A. Create the zones by using sparse root zones.

B. Set the dedup property to on and the dedupratio to at least 1.5 for the zpool. Create a separate ZFS file system for each zone in the zpool.

C. Put all of the zones in the same ZFS file system and set the dedupratio property for the ZFS file system to at least 1.5.

D. Put all of the zones in the same ZFS file system and set the dedup property for the file system to on.

E. Put each zone in a separate ZFS file system within the same zpool. Set the dedup property to on for each ZFS file system.

Your department's backup policy is to perform a full backup to remote system disk on Saturday.

On each weekday, you are to perform an incremental backup to the same remote system disk. Each incremental backup will contain only data that has been modified since the previous Saturday backup.

The server file systems must remain available at all times and can never be taken offline. The backup must not only provide for the recovery of the most recent version of a file, but must also allow recovery of previous versions of a file.

Following your company policy, which two describe the correct procedure to be performed on Saturday for backing tip the /data file system to a remote disk named /remote/backup?

A. On Saturday: zfs snapshot pool1/data@sat zfs send pool1/data@sat > /remote/backup/full

B. On Saturday: zfs create snapshotpool1/data@sat zfs send pool1/data@sat | zfs recv remote/backup/ `date' `+%m%d%y'

C. On Saturday: zfs create snapshotpool1/data@sat zfs send pool1/data@sat > /remote/backup/full

D. On Saturday: zfs create snapshotpool1/data@sat zfs send pool1/data@sat | zfsrecv remote/backup

ServerA contains two ISO images of a package repository named so1.repo.iso-a and so1.repo.iso-b respectively. You need to create a single local package repository on server that clients can connect to. The package repository will be stored on the /export/IPS file system and named repo. The preferred publisher will be named solaris and the publisher URL will be http://serverA.example.com.

Which is the correct procedure to perform on ServerA to create the local Package repository?

A. cat so1.repo.iso-a sol.repo.iso-b > so1.full.iso Mount the ISO image and use the rsync command to extract the contents of the ISO file to the /export/ IPS file system. Set the pkg/inst_root property to /export/IPS/repo and the pkg/readonly property to true. Set the preferred publisher by using pkg set-publisher -G http://pkg.oracle.com/solaris/release/ \ -g http"//serverA.example.com/ solaris

B. cat so1.repo.iso-a so1.repo.iso-b > /export/IPS/repo Set the pkg/inst_root property to true and the pkg/ readonly property to /export/IPS Set the preferred publisher by using pkg set-publisher -G http:// serverA.example.com/ \ -g http://pkg/oracle.com/solaris/rekease/solaris

C. cat so1.repo.iso-a so1.repo.iso-b > so1.full.iso Mount the ISO image and use the rsync command to extract the contents of the ISO file to /export/IPS/ repo Set the pkg/inst_root property to /export/IPS/repo and the pkg/readonly property to true Set the preferred publisher by using pkg set-publisher solaris \ -g http://pkg.oracle.com/

D. cat so1.repo,iso-a so1.repo.iso-b > /export/IPS/repo.iso Mount the ISO image and copy the repo directory from the ISO image to /export/IPS/repo set the pkg/inst_root property and the pkg/readonly property to /export/IPS/repo set the preferred pkg/inst_root property by using pkg set-publisher - G http://serverA.example.com/ \

-g http://pkg.oracle.com/solaris.com/release/- p solaris
