You need to set up a local package repository to serve 75 client systems. Multiple clients will be accessing the package repository concurrently and you need to ensure that the local repository performs very well under this heavy load, especially during package-intensive operations. Which option would ensure the best performance of the repository during package-intensive operations by multiple clients?

A. Set up multipathing on the package repository server to distribute the network load across multiple network interfaces.

B. Deploy a second instance of the package repository server to run as a read-writable mirror.

C. Deploy a second instance of the package repository server to run as a read-only mirror.

D. Deploy a second instance of the package repository server to run as a clone of the primary repository server

E. Deploy a package repository locally on each client.

You upgraded your server to Oracle bolans 11 and you imported a zpool(pooll) that was created in bolaris

10. You need to create an encrypted ZFS file system in pooll, but first you need to make sure that your server supports ZFS encryption.

Which four statements are true for support of ZFS encryption?

A. The encrypted file system must have been created in Oracle Solaris 11. To encrypt a ZFS file system from a previous version of Solaris, upgrade the zpool and create a new encrypted ZFS file system in that zpool Finally, move or copy the data from the existing ZFS file system into the new encrypted ZFS file system.

B. if you plan to create an encrypted file system in an existing zpool, the zpool must be upgraded to ZFS version 30, minimum.

C. ZFS encryption is integrated with the ZFS command set and no additional packages need to be installed.

D. ZFS encryption requires that the ZFS Dataset Encryption package be installed. E If you plan to create an encrypted file system in an existing zpool, the zpool must be upgraded to ZFS version 21, minimum. D f Encryption is supported at the pool or dataset (file system) level

E. Encryption is supported at the pool level only and every file system in the pool will be encrypted.

F. Encryption is supported at the pool level only and every file system in the pool will be encrypted.

G. You cannot create an encrypted file system in a zpool that was created prior to Oracle Solaris 11. Create a new zpool in Solaris 11, create an encrypted ZFS file system in the new zpool, and move or copy the data from the existing file system into the new encrypted file system.

alice is a user account used by Alice on a Solaris 11 system.

sadmin is a role account on the same system.

Your task is to add the command /usr/sbin/cryptoadm to the Network management profile, so that Alice

can execute it, while assuming the sadmin role.

Select the three activities necessary to accomplish this.

A. To the file /etc/security/prof_attr, add the line: Network Management: solaris:cmd:RO::/usr/sbin/cryptoadm:euid=0

B. To the file /etc/security/auth_attr, add the line: Network Management: solaris:cmd:RO::/usr/sbin/cryptoadm:euid=0

C. To the file /etc/security/exec_attr.d/local-entriies, add the line: Network Management: solaris:cmd:RO::/usr/sbin/cryptoadm:euid=0

D. Run the roles alice to ensure that alice may assume the role sadmin.

E. Run the command profiles sadmin to ensure that the role sadmin includes the network Management profile.

F. Run the command profiles alice to ensure that the Alice has permissions to access the Network management profile.

G. Run the command profiles "Network management" to ensure that the Network management profile includes the sadmin role.

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 create a flash archive of the Solaris 10 global zone on the server named sysA and you name the archive s10-system.flar.

You upgrade the operating system on sysA from Solaris 10 to Oracle Solaris 11.

On sysA, you want to create a Solaris 10 non-global zone and import the flash archive into that zone The flash archive is available on sysA via NFS through the mountpoint;/net/backup_server/backup_server.

Which two options do you choose to create the Solaris 10 zone capable of supporting the Solaris 10 flash archive? (Choose two.)

A. zonecfg -z s 10-zone create-tSYSsolarislO

B. zonecfg -z s 10-zone create setbrand=solaris10

C. zonecfg -z solarisl 0 -t SYSsolarislO

D. zonecfg -z s10-zone install -f/net/backup_setver/s1O-system.flar

The current ZFS configuration on server is:

You need to backup the /data file system while the file system is active.

Select the option that creates a full backup of the /data file system and stores the backup on server in the pool named backup.

A. Mount -F nfs system: /backup / mnt zfs snapshot pool/data@monday>/mnt/Monday

B. Mount -F nfs systemB: /backup/mnt zfs snapshot pool1/data@Monday zfs clone pool1/data@monday/mnt/Monday

C. Zfs send pool1/data@Monday | ssh system zfs recv backup/monday

D. Zfs snapshot pool1/data@Monday | ssh system zfs recv backup/monday
