B. Under Status > Dashboard > Preferences, select “Make available advanced analytics statistics” and click Apply.
C. No action is required. Advanced Statistics are enabled by default.
D. Under Configuration > Dashboard > Preferences, select “Make available advanced analytics statistics” and click Apply.

The Preferences view for enabling advanced Analytics, which will make many more statistics available.
Question: 2
A storage administrator wants to give an operator the authority to update system software. Which privilege should be assigned to the operator?
A. Hardware
B. System
C. Update
D. Services
E. Users
Answer: C
Explanation:
TABLE, User Available Scopes
Question: 3
With which option would you configure a storage pool to meet the requirement of the highest performance and high availability for random disk IOPS?
A. RAID-5
B. RAID-ZR
C. RAID-1
D. RAID-Z2
E. RAID-Z3
Answer: E
Explanation:
Z3 is triple-disk failure protection within a multiple disk set, where stripe width var pool disk count.
Data is triple mirrored, yielding a very highly reliable and high-performing system (for example, storage for a critical database). This configuration is intended for situations in which maximum performance and availability are required. Compared with a two-way mirror, a three-way mirror adds additional IOPS per stored block and higher level protection against failures.
Question: 4
A storage administrator has completed initial configuration and is going to access the BUI. What should you do to access the BUI?
A. Direct your browser to the system by using the IP address you assigned to the NET-0 port during initial configuration as follows: https://ipaddress:215.
B. Direct your browser to the system by using the IP address you assigned to the NET-1 port during initial configuration as follows: https://ipaddress:215.
C. Direct your browser to the system by using the IP address you assigned to the NET-0 port during initial configuration as follows: https://ipaddress:225.
D. Direct your browser to the system by using the IP address you assigned to the NET-1 port during initial configuration as follows: http://ipaddress:215.
Answer: A
Explanation:
The ZFSSA Browser User Interface (BUI) is the graphical tool for administration of the appliance. The BUI provides an intuitive environment for administration tasks, visualizing concepts, and analyzing performance data. The BUI provides an uncluttered environment for visualizing system behavior and identifying performance issues with the appliance.
Direct your browser to the system using either the IP address or hostname you assigned to the NET-0 The login screen appears.

Question: 5
Which two features are available when ZFS Storage Appliances are clustered?
A. A peer appliance can provide service while repairs are being performed.
B. Load balancing among multiple heads is allowed.
C. Clients are provided with a unified file system namespace across multiple appliances.
D. Rolling upgrade of software is allowed.
Answer: A,D
Explanation:
As an alternative to incurring hours or days of downtime while the head is repaired, clustering allows a peer appliance to provide service while repair or replacement is performed.
Clusters support rolling upgrade of software, which can reduce the business disruption associated with migrating to newer software.
Question: 6
What is the correct path to take a snapshot in a browser user interface (BUI)?
A. Shares > Projects
B. Configuration > Services
C. Maintenance > System
D. Status > Settings
E. Analytics > Datasets
Answer: A
Explanation:
Taking a Snapshot (BUI)
Use the following procedure to take a manual snapshot of a filesystem, LUN, or project.
1. Go to the share or project you want to snapshot.
To take a snapshot of a filesystem, 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.
Question: 7
A storage system has plenty of storage space available. Which storage profile should a storage administrator use when both high performance and high reliability are required?
A. double-parity RAID
B. striped
C. mirrored
D. single-parity RAID, narrow stripes
Answer: A
Explanation:
RAID in which each stripe contains two parity disks. As with triple mirroring, this yields high availability, as data remains available with the failure of any two disks. Double parity RAID is a higher capacity option than the mirroring options and is intended either for high-throughput sequential-access workloads (such as backup) or for storing large amounts of data with low random-read component.
Note: Triple mirrored
Data is triple mirrored, yielding a very highly reliable and high-performing system (for example, storage for a critical database). This configuration is intended for situations in which maximum performance and availability are required. Compared with a two-way mirror, a three-way mirror adds additional IOPS per stored block and higher level protection against failures.
Question: 8
Which four are key attributes to set up a ZFS Storage Appliance for Microsoft Exchange?
A. serial number of ZFS storage appliance
B. read/write SSD configured
C. RAID1
D. block size 4k
E. iSCSI protocol
Answer: A,B,C,E
Explanation:
B: The transactional log and database elements of ZFS send synchronous writes that require acknowledgment from persistent media. For this reason, Write Flash Acceleration SSDs greatly improve the write performance of the ZFS Storage Appliance.
E: The implementation of Exchange 2010 and 2007 on the Sun ZFS Storage 7420 can use both iSCSI and Fibre Channel target modes.
Question: 9
Which three actions are performed to maintain data availability?
A. Software services are set to manually restart in case of software failure.
B. A set of rolling snapshots of two preceding software installs is maintained during software upgrades.
C. A set of rolling snapshots of preceding software installs is maintained during software upgrades.
D. The appliance configuration is backed up and exported.
E. Solaris Live Upgrade is used to minimize software updates and upgrades.
F. Software services are automatically restarted in case of software failure.
Answer: C,D,F
Explanation:
C: The majority of new features and bug fixes introduced in a system update are backward-compatible and allow you to roll back to previous updates without issue. These are applied automatically by the storage management software.
D: The configuration backup function enables the administrator to backup the appliance configuration, consisting of system metadata only (such as the network configuration, local users and roles, service settings, and other appliance metadata).
F: To maximize the availability of your data in production, the ZFSSA includes a complete end-to-end architecture for data integrity, including redundancies at every level of the stack. Key features include the following:
Question: 10
Which four actions must you perform to access Active Directory (AD) in order to create appropriate authentication permissions?
A. Enter the details of a domain administrator who has the authority to allow the Oracle ZFS Storage Appliance to join Active Directory (AD).
B. Enter the object class mappings for posixAccount and shadowAccount.
C. From the Configuration > Services > Active Directory page, click the Join Domain button.
D. Ensure that the clocks on the Oracle ZFS Storage Appliance and Windows Active Directory (AD) domain controllers are synchronized.
E. Ensure that the Domain Name Server (DNS) configuration refers to the same DNS server as the Active Directory servers.
Answer: A,C,D,E
