Which three tasks can be performed using the Compellent vSphere plugin in the vSphere client? (Choose
An engineer is testing controller failover on a newly installed Storage Center.
Which process should the engineer use?
The engineer notices that iSCSI servers are NOT performing as expected. After reviewing the graphics, the
engineer identifies high latency due to an excessive number of retransmits.
What is causing the performance issue?
An engineer is installing an SC4020 with four fibre channel (FC) ports in each controller and two FC switches
configured in a dual fabric. The replication ports on the controller will be used only to replicate data to another
How many fault domains are required in Virtual Port mode?
A Storage Center runs in Legacy Port mode.
How should the Storage Center zone(s) be set up?
A Storage Center system has 6 connections to a FC switch. The Storage Center is in Virtual Port mode.
How many members are in a server zone?
A storage administrator creates a new volume, applies the Recommended Storage Profile, and writes 9 TB of
data to that new volume. This data currently resides in Tier 1, RAID 10. The storage array has three distinct
tiers of drives (SSD, 15K, and 10K). The storage administrator is concerned that Tier 1 space is close to being
fully used and will start to cause performance issues.
When will the storage administrator begin to see volume data move between Tier 1 and Tier 2?
A local Storage Array replicates to a remote Storage Array. A problem occurs on the local Storage Array, which
causes the engineer to failover to the remote Storage Array. Once the problem is fixed, the engineer needs to
fail back to the local Storage Array. When the engineer tries to fail back to the local Storage Array, NO volumes
are available to fail back.
What is the cause of the problem?
An engineer configures a new SC4020. The same day, the engineer receives an alert that all disks are being
seen on only one path.
What are two reasons for this alert? (Choose two.)
