Q41. You need to migrate a UFS file system named /production_ufs to a ZFS file system named /production_ufs. The /production_ufs file system cannot be taken down or be out of production during the migration, and the current /production_ufs file system must remain active until the /ptoduction_zfs file system is copied and ready.
Which method allows you to meet both requirements?
1. Copy live data from /production_ufs to /production_zfs while /production_ufs is in use.
2. When the copy is complete, /production_zfs will contain an up-to date copy of /production_ufs
A. Create a snapshot of the UFS file system.
Create the new ZFS file system.
Use cpio to copy data from the snapshot to the new ZFS file system.
B. Create a new Boot Environment.
Create the ZFS file system.
Use lucreate -m to copy data from the Current UFS file system to the new ZFS file system.
C. Mirror the existing UFS file system by using SVM.
After both submissions are in sync, migrate one of the submissions to a ZFS file System by using
D. Create the new ZFS file system by using zfs create import to import data from the existing UFS file system into the new ZFS file system
E. Create the new zfs file system by using the zfs create -oshadow.
Q42. Which five statements describe options available for installing the Oracle Solaris 11operating system using the installation media?

Q43. You are setting up a local IPS package repository on your Oracle Solaris11 server:
You want to point the existing local IPS publisher to the new local IPS repository located in /repo.
These are the stops that you have followed:
1. Download and rsync the contents of the Oracle Solaris11 repository ISO image to the /repo directory.
2. Configure the repository server service properties. The svcprop command display, the IPS related properties:
pkg/readonly Boolean true
The 1s command displays the contents of the /repo directory:
The svcs publisher command shows the svc: /application/pkg/server: default service is online.
The pkg publisher command shows the svc: /application/pkg/server: default service is online.
The pkg publisher command still displays:
Which steps needs to be performed to set the local IPS publisher to the local IPS repository/repo?
A. Issue the pkgrepo refresh-s command to refresh the repository.
B. Restart thesvc:/application/pkg/server:default service.
C. pkg set-publisher command to set the new repository location.
D. Issue the pkgrepo rebuild command to rebuild the repository.

B. Internet protocol security
C. Diffie-Kerberos coaxial key encryption
D. Signed cryptographic plugins (providers)
E. Kernel support for signed antivirus plugins
Q45. 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 thezpool.
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 thededupproperty to on for each ZFS file system.
