Oracle ZFS Storage Appliance Implementation Essentials

1.

Which connection should you use for the initial configuration of a ZFS Storage Appliance in order to monitor progress on the console?

serial SP connection network SP connection cluster I/O connection PCIe connection SAS-3 HBA connection

2.

Which two actions make a statistic into an archived data set?

monitoring the statistic in Analytics > Open Worksheet for more than one hour clicking the archive (tape) icon in Analytics > Open Worksheet using "Add statistic saving the statistic in a Worksheet zooming out to more than one hour, and then pausing the statistic

3.

Which is the most effective metric for identifying performance issues?

IOPS latency throughput percent utilization capacity

4.

What is the interface of the ZFS Storage Appliance to access the Oracle Storage Cloud Service?

Snap Management tool Upload CLI tool Java Library RESTful management API

5.

Which four factors must you consider for implementing remote data replication between two ZFS Storage Appliances?

enough storage space to receive the replica in the target site Write ordering and write consistency in maintained at the granularity of the replicated component. Synchronous mode is not supported. business processes, such as service-level agreements (SLA) the number of concurrent users in the target site

6.

A customer requests a software upgrade of ZFS storage cluster pairs without any down time. Which option meets this requirement?

an upgrade that rolls together all preceding updates an upgrade that is rolled out to both controllers simultaneously clustered controllers that are upgraded one at a time ("rolling" from one to the next) such that, at any given time, the controller being upgraded controls noresources cluster controllers that are rolled through software upgrades one by one, keeping both controllers at the same version at all times in case of failover

7.

You encounter an error while starting data replication on a remote ZFS appliance. Which four must you ensure to troubleshoot this problem?

Data replication is in synchronous mode. Each head in the source can ping the other head in the target. The target has been set up properly. The replication service has been enabled on both the source and the target. The replication action has been set up properly.

8.

You want to configure a LUN on a ZFS Storage Appliance by using the browser user interface (BUI). In which two ways can you configure multiple initiator groups per LUN?

Go to Configuration > Storage. Click the plus sign next to available Pools. Enter a new pool name and click APPLY. Go to Shares > LUN > Edit> Protocols. Edit the initiator group LUN number, and select multiple initiator groups to the given LUN. Go to Shares > LUNs. Click the plus sign to create a new LUN. Then select multiple initiator group(s) by pressing the Ctrl key. Go to Configuration > SAN > Fibre Channel. Click the plus sign to create a new initiator. Then enter the World Wide Name (WWN) of the FC Initiator.

9.

Which two actions would you take if a rolling upgrade procedure fails with an unexpected error?

Retry the failed upgrade by using the CLI or BUI in case of a transient error. Contact the storage administrator or support provider. Factory-reset both the controllers. Perform a series of takeovers and failbacks until the cluster operates normally. Use the operating system shell to manually restart the upgrade.

10.

After you set up a network connection between a host and ZFS Storage Appliance, the connection is set to half duplex. What are two possible causes of this problem?

Multiple IP addresses are linked to the host. There are duplicate IP addresses on the same network. There is a broken cable or NIC port. The network switch is not set to auto-negotiation.
