You have already generated a 256-bit AES raw key and named the keystore file /mykey. You need to use the key to create an encrypted file system.

Which command should you use to create a ZFS encrypted file system named pool1/encrypt using the /mykey keystore?

A.

zfs create - o encryption = /mykey pool1/encrypt

B.

zfs create - o encryption = 256-ccm - o keysource = raw, file : ///my key pool1/encrypt

C.

zfs create - o encryption = AES keysource = /mykey pool1/encrypt

D.

zfs create - o encryption = on keystore = /mykey pool1/encrypt

You are using this rule file with the Basic Audit Reporting Tool (BART) to detect inappropriate file system changes.

Identify three options that describe the new Oracle Solaris 11 zone features.

A.

There are boot environments for zones.

B.

Administrators can delegate common administration tasks by using RBAC.

C.

Oracle Solaris 11 supports Solaris 8, 9, and 10 branded zones.

D.

You can migrate a physical Solaris 10 system and its non-global zones to a solaris10 branded zone running on an Oracle Solaris 11 system.

E.

It is possible to change the host ID of a zone.

Review the zonestat command:

zonestate - q physical - memory -R high -z -p -p “zones” 10 24h 60m

Select the option that correctly describes the information that is displayed by this command.

A.

It is a sample of dbzone’s physical memory usage taken every hour over a 24-hour period.

Only the top 10 samplings of peak memory usage are displayed.

All other utilization data is eliminated.

B.

It is a sample of dbzone’s CPU, virtual memory, and networking utilization.

Physical memory is executed from the report.

The sampling is taken every 10 minutes over a 24-hour period and peak utilization id displayed each hour.

C.

It is a sample of dbzone’s CPU, virtual memory, and networking utilization.

Physical memory is executed from the report.

The sampling is taken every 10 minutes over a 24-hour period and displayed each hour.

D.

It is a sample of dbzone’s physical memory usage taken every 10 seconds and 24-hour period.

Only peak virtual memory usage and CPU utilization are displayed each hour.

All other Utilization data is eliminated.

E.

It is a sample of dbzone’s physical memory usage taken every 10 seconds and 24-hour period.

Only peak memory usage is displayed each hour.

All other utilization data is eliminated.

The resource control in your zone is:

rcll

name: zone.cpu-shares

value: (pnv=phvJleged,limit=20,aclion=none)

When you boot the zone, this message is displayed:

WARNING: The zone.cpu-shares rctl is set but FSS is not the default scheduling class for this zone. FSS will be used for processes in the zone but to get the full benefit of FSS, it should be the default scheduling class.

Which option will resolve this issue?

A.

in the global zone, run this command to change the process scheduler for the global zone dispadmin -d FSS

B.

in the non-global zone, run this command to change the process scheduler for this specific zone: dispadmin -d FSS

C.

Change the zone resource control to:

value: (priv=privileged,limit=20,action=none,default)

D.

Use svccfg to modify the general/scheduler property in the svc:/system/zones:default service:

svccfg -s system/zones:default editprop general/scheduler=FSS

You have been tasked with creating a dedicated virtual network between two local zones within a single system. In order to isolate the network traffic from other zones on that system.

To accomplish this, you will create__________.

A.

An ether stub

B.

A virtual router

C.

A virtual switch

D.

A virtual bridge.

E.

A virtual network interface

F.

Nothing because a virtual switch is automatically created then the virtual network interfaces are created.

(Choose tnree.)

A.

Publish to a local file-based repository.

B.

Publish as an SVR4 package.

C.

Publish to a remote HTTP-based repository.

D.

Convert to a p5p package archive.

E.

Convert to a SVR4 package archive.

F.

Publish as a tar archive.

G.

Publish as a directory on a USB or DVD drive.

Which two accurately describe the Image Packaging System (IPS) components? (Choose two.)

A.

Every package is represented by an FMRI, consisting of a publisher, a name, and a version, with the scheme.

B.

Every package is represented by a manifest, consisting of a publisher, a name, and a version, with the scheme.

C.

A publisher is an entity that develops and constructs packages.

D.

a repository is an entity that publishes and provides access to packages.

You are setting up a local IPS package repository on your Oracle Solaris 11 server; solans example.com

You want to point the existing local IPS publisher to the new local IPS repository located in /repo. These are the steps that you have followed:

1 Download and rsync the contents of the Oracle Solaris 11 repository ISO image to the /repo directory.

2. Configure the repository server service properties. The svcprop command displays the IPS-related properties:

pkg/inst_root astnng /repo pkg/readonly boolean true

The Is command displays the contents of the /repo directory:

#ls /repo

pkg5 repository publisher

The svcs command shows the svc:/application/pkg/server:default service is online.

The pkg publisher command still displays:

PUBLISHERTYPESTATUSURI solarisoriQinonlinehttp://DkQ.Qracle.conVsolaris/release/

Which step 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 the svc:/application/pkg/server:default service.

C.

issue the pkg set-publisher command to set the new repository location.

D.

issue the pkgrepo rebuild command to rebuild the repository.

E.

issue the pkgrepo set command to set the new repository location-

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.
