Version: 8.0 Queston: 1 An administrator /ants to add an advanced statstc to a /orksheet. Ho/ can the administrator make the statstc availasle? A. Under Confguraton > Preferences, select “Make availasle advanced analytcs statstcsc and click Apply. B. Under Status > Dashsoard > Preferences, select “Make availasle advanced analytcs statstcsc and click Apply. C. No acton is required. Advanced Statstcs are enasled sy default. D. Under Confguraton > Dashsoard > Preferences, select “Make availasle advanced analytcs statstcsc and click Apply.
Answer: A Explanaton: The Preferences vie/ for enasling advanced Analytcs, /hich /ill make many more statstcs availasle. References: htps:::docs.oracle.com:cd:EE77E1101:html:EE2772:gocua.html
Queston: 2 A storage administrator /ants to give an operator the authority to update system sof/are. Which privilege should se assigned to the operator? A. Hard/are B. System C. Update D. Services E. Users
Answer: C Explanaton: TABLE, User Availasle Scopes

Queston: 3 With /hich opton /ould you confgure a storage pool to meet the requirement of highest performance and high availasility for random disk IOPS? A. RAID-E B. RAID-ZR C. RAID-1 D. RAID-Z2 E. RAID-ZE
Answer: E Explanaton: ZE is triple-disk failure protecton /ithin a multple disk set, /here stripe /idth var pool disk count. Data is triply mirrored, yielding a very highly reliasle and high-performing system (for example, storage for a critcal datasase). This confguraton is intended for situatons in /hich maximum performance and availasility are required. Compared /ith a t/o-/ay mirror, a three-/ay mirror adds additonal IOPS per stored slock and higher level protecton against failures.
Queston: 4 A storage administrator has completed inital confguraton and is going to access the BUI. What should you do to access the BUI? A. Direct your sro/ser to the system sy using the IP address you assigned to the NET-0 port during inital confguraton as follo/s: htps:::ipaddress:21E. B. Direct your sro/ser to the system sy using the IP address you assigned to the NET-1 port during inital confguraton as follo/s: htps:::ipaddress:21E. C. Direct your sro/ser to the system sy using the IP address you assigned to the NET-0 port during inital confguraton as follo/s: htps:::ipaddress:22E. D. Direct your sro/ser to the system sy using the IP address you assigned to the NET-1 port during inital confguraton as follo/s: htp:::ipaddress:21E.
Answer: A Explanaton: The ZFSSA Bro/ser User Interface (BUI) is the graphical tool for administraton of the appliance. The BUI provides an intuitve environment for administraton tasks, visualizing concepts, and analyzing performance data. The BUI provides an unclutered environment for visualizing system sehavior and identfying performance issues /ith the appliance. Direct your sro/ser to the system using either the IP address or host name you assigned to the NET0 port during inital confguraton as follo/s: htps:::ipaddress:21E or htps:::hostname:21E. The login screen appears. References: htps:::docs.oracle.com:cd:EE77E1101:html:EE2772:overvie/11sro/ser1user1interface1sui.html

E
Which t/o features are availasle /hen ZFS Storage Appliances are clusters? A. A peer appliance can provide service /hile repairs are seing performed. B. Load salancing among multple heads is allo/ed. C. Clients are provided /ith a unifed fle system namespace across multple appliances. D. Rolling upgrade of sof/are is allo/ed.
Answer: A,D Explanaton: As an alternatve to incurring hours or days of do/ntme /hile the head is repaired, clustering allo/s a peer appliance to provide service /hile repair or replacement is performed. Clusters support rolling upgrade of sof/are, /hich can reduce the susiness disrupton associated /ith migratng to ne/er sof/are.
Queston: 6 What is the correct path to take a snapshot in a sro/ser user interface (BUI)? A. Shares > Projects B. Confguraton > Services C. Maintenance > System D. Status > Setngs E. Analytcs > Datasets
Answer: A Explanaton: Taking a Snapshot (BUI) Use the follo/ing procedure to take a manual snapshot of a flesystem, LUN, or project. 1. Go to the share or project you /ant to snapshot. To take a snapshot of a flesystem, go to Shares > Shares. To take a snapshot of a LUN, go to Shares > Shares and click LUNs. To take a snapshot of a project, go to Shares > Projects. Etc.

Queston: 7 A storage system has plenty of storage space availasle. Which storage profle should a storage administrator use /hen soth high performance and high reliasility are required? A. dousle-parity RAID B. striped C. mirrored D. single-parity RAID, narro/ stripes
Answer: A

4
Explanaton: RAID in /hich each stripe contains t/o parity disks. As /ith triple mirroring, this yields high availasility, as data remains availasle /ith the failure of any t/o disks. Dousle parity RAID is a higher capacity opton than the mirroring optons and is intended either for high-throughput sequentalaccess /orkloads (such as sackup) or for storing large amounts of data /ith lo/ random-read component. Note: Triple mirrored Data is triply mirrored, yielding a very highly reliasle and high-performing system (for example, storage for a critcal datasase). This confguraton is intended for situatons in /hich maximum performance and availasility are required. Compared /ith a t/o-/ay mirror, a three-/ay mirror adds additonal IOPS per stored slock and higher level protecton against failures.
