View the data relocation progress between tiers.

Enable scheduled data relocation for a specific pool.

Exclude pool from the data relocation schedule.

Modify data relocation schedule at the system level.

NO.16 For managing VMware datastore storage resources, which protocols are supported by Dell Unity systems?

iSCSI and NFS

SMB only

NVMe over Fabrics

Fibre Channel and FCoE

NO.17 Describe the process for managing NAS client access to SMB and NFS file storage resources.

Requires a separate NAS server for each protocol

Unified NAS server can serve both SMB and NFS clients

Access based on IP whitelisting only

Integration with Active Directory for SMB and NFSv4

NO.18 A storage administrator is tasked with configuring a density-based Host I/O policy based on the following requirements:
– Resource Size: 400 GB LUN
– Density Limit: 15 IOPS
What is the total IOPS set by this policy?

4000

6500

8000

6000

NO.19 When managing Dell Unity XT support, which of the following functionalities are available?

Automated support notifications (Proactive Assist)

Manual case creation

Remote system diagnostics

Live chat support

NO.20 When performing snapshot operations on storage resources, what capabilities are available?

Creating read-only and read-write snapshots

Automatically deleting old snapshots based on policies

Snapshots consuming additional storage only when data changes

Limiting the number of snapshots per LUN to 10

NO.21 Refer to the exhibit. Which ports are used to connect DAEs to a Unity XT storage array?

NO.22 What are four constraints defined in a VMware Capability Profile?

Protocol Endpoint, Drive Type, RAID Level, and VM UUID

Capacity, Drive Type, RAID Level, and Data Reduction

Service Level, Drive Type, RAID Level, and Space Efficiency

Service Level, Access, Protocol, and Space Efficiency

NO.23 Which two vVol object types can have a snapshot? (Select 2)

Mem

Data

Config

Swap

NO.24 A company has an ESXi host installed with FC HBAs that is connected to a Dell Unity XT storage array. A 500 GB LUN is provisioned to this host from the Unity array and is in production. The VMware administrator has configured a new vSwitch with the NICs on the server intended for iSCSI traffic. The storage administrator is asked to configure software iSCSI and provision a new
1 TB LUN from the storage array using iSCSI.
What is a consideration when satisfying this request?

Two iSCSI target interfaces must be configured with IP addresses from separate subnets.

A connection must be established between the host iSCSI initiators and Unity iSCSI targets before provisioning the new LUN.

Any single host should connect to any single array using one protocol only.

NO.25 A storage administrator has configured an SMB share with the Pool Automatic Deletion retention policy. With default settings applied, what will happen when the pool crosses 95%? A The default setting is that no snapshots will be deleted automatically.

The Dell Unity system will delete snapshots until 85% pool space is reached.

When the snapshot reaches 25% of the pool size, snapshots will be deleted until 20% of the pool size is reached.

The Dell Unity system will only delete the oldest snapshot of the configured schedule.

NO.26 A storage administrator is tasked with creating a DR solution for block and file storage resources on a Dell Unity XT 680F system at a primary production site.
The company has two other campus locations:
– Campus A is located 50 km (31 mi) away and has a Dell Unity XT 480 Hybrid system.
– Campus B is located 200 km (124 mi) away and has a Dell UnityVSA system.
What should the storage administrator do to provide the best protection of storage resources while meeting recommended latency levels?
