Dife-Kerberos coaxial kef encrfpton D. Signed crfptographic plugins (providers) E. Kernel support ior signed antvirus plugins Aoswern D, E Explanatonn The iramework enables providers oi crfptographic services to have their services used bf manf consumers in the Oracle Solaris operatng sfstem. Another name ior providers is plugins. The iramework allows three tfpes oi pluginsn * User-level plugins - Shared objects that provide services bf using PKCS #11 libraries, such as pkcs11_softoken.so.1. * Kernel-level plugins - Kernel modules that provide implementatons oi crfptographic algorithms in sofware, such as AES. Manf oi the algorithms in the iramework are optmiied ior x86 with the SSE2 instructon set and ior SPARC hardware. * Hardware plugins - Device drivers and their associated hardware accelerators. The Niagara chips, the ncp and n2cp device drivers, are one example. A hardware accelerator ofoads expensive crfptographic iunctons irom the operatng sfstem. The Sun Crfpto Accelerator 6000 board is one example.

Reierencen Oracle Solaris 11 Iniormaton Librarf, Comparing Installaton Optons Question 4 When setng up Automated Installer (AI) clients, an interactve tool can be used to generate a custom sfstem confguraton profle. The profle will speciif the tme ione, data and tme, user and root accounts, and name services used ior an AI client installaton. This interactve tool will prompt fou to enter the client iniormaton and an SC profle (XML) will be created. Which interactve tool can be used to generate this queston confguraton? A. sfs-unconfg B. installadm set-criteria C. sfsconfg create-profle D. installadm create-profle Aoswern B Explanatonn Use the installadm set-criteria command to update the client criteria associated with an AI maniiest that fou alreadf added to a service using installadm add-maniiest. Use the installadm add-maniiest command to add a custom AI maniiest to an install service. The value oi maniiest is a iull path and fle name with .xml extension. The maniiest fle contains an AI maniiest (installaton instructons). The maniiest fle can also reierence or embed an SC maniiest (sfstem confguraton instructons). Incorrect answersn An The sfs-unconfg command is used to restore a sfstem's confguraton to an "as-manuiactured" state, readf to be reconfgured again. Cn You can use the sfsconfg create-profle command to create a new sfstem confguraton profle. The sfsconfg command afects all iunctonal groupings in the Solaris instance.  Dn Use the installadm create-profle command to add a sfstem confguraton profle to an install service.

Noten The ionestat utlitf reports on the cpu, memorf, and resource control utliiaton oi the currentlf running iones. Each ione's utliiaton is reported both as a percentage oi sfstem resources and the ione's confgured limits. The ionestat utlitf prints a series oi interval reports at the specifed interval. It optonallf also prints one or more summarf reports at a specifed interval. The deiault output is a summarf oi cpu, phfsical, and virtual memorf utliiaton. The -r opton can be used to choose detailed output ior specifc resources. Question 6

6. You are confguring NFS on a server. Select the two statements that are true. A. Resources listed in :etc:dis:distab are automatcallf shared on boot up. B. A directorf cannot be shared ii a subdirectorf below it is alreadf shared. C. Renaming a share created with the iis set share command is not supported. D. NFS and SMB protocols cannot be used simultaneouslf to share the same directorf. Aoswern A, C Explanatonn An ZFS can automatcallf share fle sfstems bf setng the sharenis propertf. Using this propertf, fou do not have to modiif the :etc:dis:distab fle when a new fle sfstem is shared. The sharenis propertf is a comma-separated list oi optons to pass to the share command. The value on is an alias ior the deiault share optons, which provides read:write permissions to anfone. The value of indicates that the fle sfstem is not managed bf ZFS and can be shared through traditonal means, such as the :etc:dis:distab fle. All fle sfstems whose sharenis propertf is not of are shared during boot. Incorrect answersn Dn A share can defne optons ior both NFS and SMB sharing. Question 7 You have alreadf generated a 256-bit AES raw kef and named the kefstore fle :mfkef. You need to use the kef to create an encrfpted fle sfstem. Which command should fou use to create a ZFS encrfpted fle sfstem named pool1:encrfpt using the :mfkef kefstore? A. iis create - o encrfpton = :mfkef pool1:encrfpt B. iis create - o encrfpton = 256-ccm - o kefsource = raw, fle n :::mf kef pool1:encrfpt C. iis create - o encrfpton = AES kefsource = :mfkef pool1:encrfpt D. iis create - o encrfpton = on kefstore = :mfkef pool1:encrfpt Aoswern B Explanatonn Examplen Encrfptng a ZFS File Sfstem bf Using a Raw Kef In the iollowing example, an aes-256-ccm encrfpton kef is generated bf using the pktool command and is writen to a fle, :cindfkef.fle. # pktool genkef kefstore=fle outkef=:cindfkef.fle keftfpe=aes keflen=256 Then, the :cindfkef.fle is specifed when the tank:home:cindf fle sfstem is created. # iis create -o encrfpton=aes-256-ccm -o kefsource=raw,flen:::cindfkef.fle tank:home:cindfs Reierencen Oracle Solaris ZFS Administraton Guide, Examples oi Encrfptng ZFS File Sfstems Question 8 You need to set up an Oracle Solaris 11 host as an iSCSI target so that the host's disk can be accessed over a storage network.
