Identify two options that can be selected when customizing the Status Dashboard performance graphs.
NFSv4 - ops/sec
CPU - Average Wait I/O Time
Which two properties are available when creating alerts based on statistics from Analytics?
Timing: for at least
Which two options describe the data services Oracle ZFS Storage Appliances provide?
The iSCSI service supports discovery, management, and configuration using the iSNS protocol.
For shadow migrations, in order to properly migrate data, the source file system or directory must be read-only.
Which three are good reasons to have multiple pools configured?
There are multiple workload types sharing the same ZFS Storage Appliance.
There is a need to separate different storage environments from each other (that is, production, development).
There is a need to have multiple pools of the same Raid level.
The ZFS Storage Appliance has the ability to archive data sets (statistics)_________.
For one month at one second granularity, and then 12 months at one hour granularity
Which factor has the maximum impact on performance in sequential read environments?
The number of Write-Optimized SSDs
A storage administrator is configuring the ZFS Storage Appliance for applications with large block random read and write I/O and mixed block size of sequential read and write I/O. What should be the optimal record size?
Identify the proper procedure to power up the ZFS Storage Appliance.
Connect cords to power supply 0 and power supply 1, and wait for 2 minutes.
What happens to a shadow migration job if a pool is failed over in a cluster, or both system disks fail and a new head node is required when using shadow migration feature?
All data necessary to continue shadow migration without interruption is kept with the storage pool.
What is the effect of a snapshot rollback on a clone?
If the clone was promoted prior to the snapshot rollback, no impact will be noticed.
A storage administrator needs to restore data from a snapshot. Identify three valid solutions.
Mount the snapshot LUN and copy the data back.
Mount the share, change directories into the .zfs directory of the share, find the snapshot (time sequenced), and copy the data.
Backup and restore the data from tape.
Which storage profile serves data the fastest for random disk IOPS?
A storage administrator has identified that the storage system has plenty of storage space available. Which storage profile should be used when both high performance and high reliability are required?
Which three statements are true about Cluster Configuration of ZFS Storage Appliances?
In Cluster environment, only one node at a time can be the owner of each storage pool.
To utilize resource of both nodes simultaneously, you need at least two storage pools: one that maps to node1 and another that maps to node2.
In Cluster environment, only one controller can be assigned resources.
Which tool must you use to identify single or multiple devices at 100% utilization, minimum and maximum device utilization, and device utilization balance, all over time (performance analysis)?
A heat map showing quantized distribution
When is the password for the Browser User Interface access set?
After logging in through the Browser User Interface and after the configuration is complete
Which two groups' tasks become easier when a share is published?
Users who are using the Find feature of the Start menu to find remote shares based on identifier or description
Users trying to find shares in large Active Directory environments
Which two protocols are required when implementing HCC?
In which section of the Browser User Interface (BUI) can a storage administrator create snapshots?
What happens when the Thin Provisioning property is set for a LUN?
This property allows the volume size to exceed the amount of available space.
How do you disable a specific version of NFS in ZFS storage appliance?
Disable the NFSv4 delegation.
Which feature should be enabled to secure communications between the ZFS Storage Appliance and an LDAP server?
A storage administrator wants to configure the "Cache Profile". Which is a valid configuration type?
Which interface port is typically used to conduct the initial system configuration?
Which is a definite performance issue for clients of the ZFS storage appliance?
high CPU percent utilization
Identify the three levels of upgrades that are available.
Micro: Designed to fix bugs within 24 to 48 hours
Minor: Designed to add new features
Major: Big feature revisions
Identify two items for file-sharing deployments.
Identify the two ways in which the ZFS Storage Appliance provides data integrity.
ZFS operations are copy-on-write transactions, so the on-disk state is always valid.
Every block is checksummed in server memory to prevent silent data corruption.
The storage administrator wants to configure a snapshot in the ZFS storage ZS3. Which option must the administrator use to ensure application consistency?
Quiesce, sync, or shut down the application and then take a snapshot of the master LUN.
Streaming read workloads are usually best served from___________.
DRAM, followed by read cache devices
Which two things should be considered for site planning?
The total airflow requirements of all equipment installed in the rack to ensure that the equipment is operated within its specified temperature range
The temperature in the rack does not exceed the controller's maximum ambient rated temperature
Which configuration provides maximum availability and performance?
Identify the rack configuration that is not compatible for installing the ZFS Storage Appliance.
Two post-EIA compliant cabinet
Which two capabilities are available when ZFS Storage Appliances are clustered?
Allows a peer appliance to provide service while repair is performed
Allows rolling upgrade of software
Which is the most effective metric for identifying performance issues?
What should be the difference between the Domain Controller and appliance clocks to cause the ZFS Storage Appliance to not properly join an Active Directory domain?
A storage administrator is configuring replication for a share. Identify the two required fields that must be specified.

The target storage pool
Hybrid Columnar Compression is unique to Oracle Storage. How many times can you get better compression with HCC versus competitive options?
Which option is true when allocating and verifying storage?
In general, half JBODs are the preferred unit for managing storage, but quarter JBODs can be used where storage needs are small.
