Dell PowerStore Deploy v2
Exam
2 / 10
1.An engineer is planning management and iSCSI storage networking for a PowerStore T appliance
using the documented Gen 1/Gen 2 deployment workflow. The approved switch design permits both
networks to use VLAN 110. The management network must remain 10.40.10.0/24 on VLAN 110. Routing
and physical connectivity have been validated separately.
Which storage-network entry satisfies PowerStore's subnet-separation requirement while retaining the
approved shared VLAN?
A. Subnet 10.40.10.0/24; VLAN 120.
B. Subnet 10.40.20.0/24; VLAN 110.
C. Subnet 10.40.10.0/24; VLAN 110.
D. Subnet 10.40.20.0/24; VLAN 120.
Answer: B.
Explanation:
B keeps the approved VLAN while giving storage a subnet distinct from management. PowerStore
permits the two networks to share a VLAN, but their subnets must differ.
2.An engineer must add two existing host objects to the iSCSI host group HG-APP on PowerStore. The
five candidates are configured as follows. Their initiators are registered correctly, and there are no
additional eligibility restrictions.
Host Transport
Existing volume
mappings
Current host-group
membership
app-a iSCSI None None
app-b FC None None
app-c iSCSI
One directly mapped
volume
None
app-d iSCSI None None
app-e iSCSI None HG-OTHER
Which two hosts can be added immediately without changing their current configuration?
A. app-a
B. app-b
C. app-c
D. app-d
E. app-e
Answer: A and D.
Explanation:
app-a and app-d use the group's transport, have no existing volume mappings, and do not belong to
another host group.
3.A PowerStore agentless block import session is in Ready To Enable Destination Volume. Import
compatibility, source connectivity, and destination host configuration have already been validated. The
application is still using the source volume.
3 / 10
Place the following actions in the order needed to reach Copy In Progress. Treat each item as one
completed action. Use every StepID once. Cutover is outside the scope of this question.
Items
- S1: Select Start Copy for the import session.
- S2: Shut down the application accessing the source volume.
- S3: Enable the destination volume and ensure the application's source-volume mappings are removed,
by the orchestrator or manually as appropriate, while preserving PowerStore's access needed for import.
- S4: Rescan the host, reconfigure the application to use the PowerStore destination volume, and bring
the application back up.
Write the ordered StepID sequence.
Answer: S2 → S3 → S4 → S1.
Explanation:
Stop the source application before enabling its destination. During destination enablement, handle
removal of the application's source mappings using the applicable orchestrated or manual path.
Preserve the access PowerStore requires to import data.
Once the session reaches Ready to Start Copy, rescan the host, reconfigure the application to the
destination, and bring it up. Then select Start Copy.
4.A storage administrator must configure automatic local snapshots for the standalone block volume
ENG-REPORTS in PowerStore Manager. Use the documented snapshot-rule and protection-policy
workflow. This is a written workflow exercise; no live system is provided.
Initial State
- ENG-REPORTS is not a volume-group member and has no protection policy.
- The cluster is healthy; administrative access, capacity, and snapshot-limit headroom have been
checked.
- An existing rule named Shared-Daily is used by other production policies. Its settings and all objects
using it must remain unchanged.
- The required new rule and policy names are available.
- Standard local snapshots are required; remote replication, remote backup, and secure snapshots are
not requested.
Task
Describe how you would create protection that takes a snapshot every four hours on every day of the
week and retains each automatically created snapshot for 48 hours. Include the target-resource
assignment and the evidence you would inspect after deployment. You may create the rule separately or
while creating the new policy.
Expected Outcome
ENG-REPORTS receives the requested automatic local protection. Existing production rules and policies
remain unchanged. Your answer must distinguish configuration checks from evidence that the schedule
actually ran.
Answer:
1. Confirm the target identity and standalone status, and recheck that no policy has been assigned since
planning. Use new objects rather than editing Shared-Daily.
2. In Protection > Protection Policies > Snapshot Rules, create a new rule such as ENG-4H-48H. Select
every day, an interval of four hours, and a retention of 48 hours (two days). Leave secure snapshots
4 / 10
unselected.
3. Create a new protection policy such as ENG-LOCAL. Include the new snapshot rule without
replication or remote-backup rules.
4. Under Storage > Volumes, select ENG-REPORTS and use Protect > Assign Protection Policy to apply
ENG-LOCAL.
5. Verify the configuration and subsequently observe scheduled results as described below.
Creating the snapshot rule inside the new-policy workflow is equally valid. Assigning the policy from the
volume's protection view is also valid. Equivalent object names earn full credit. Merely creating the rule
and policy, without assignment, does not protect the volume.
Validation
Check that ENG-REPORTS shows the intended policy, its policy includes the intended rule, and that rule
has all days, the four-hour interval, and 48-hour retention. Confirm Shared-Daily and its existing
assignments remain unchanged.
After scheduled runs, inspect automatically created snapshots for ENG-REPORTS, including creation
and expiration timestamps. Observe multiple scheduled results to assess the configured cadence; do not
treat an immediate manually created snapshot as proof that the automatic schedule ran. Retention
should be assessed relative to each snapshot's creation time, rather than the policy-creation time.

Award only the points supported by the answer; the split entries allow partial credit. Valid equivalent GUI
paths are accepted. An answer that modifies Shared-Daily, omits assignment, or specifies the wrong
schedule/retention does not meet the task, even if it earns partial points. No execution success is
claimed by this written exercise.
5 / 10
5.During post-deployment validation, a PowerStore asynchronous volume-replication session repeatedly
misses its required 15-minute RPO. Initial synchronization has finished. The business has not approved
a longer RPO.
The engineer collects these observations during the affected period:
Observation Result
Replication session Running, not administratively paused
Source and destination No relevant resource alerts; destination capacity is sufficient
Changed-data workload
Sustained demand exceeds measured replication
throughput
Shared WAN link
Saturated during competing transfers; packet loss is
observed
Replication progress Backlog keeps growing
Which action best addresses the observed problem while retaining the required protection objective?
A. Increase the alert threshold and check that warnings stop, leaving the replication transport
unchanged.
B. Increase the RPO to 60 minutes and check that subsequent synchronization finisheswithout a
compliance warning.
C. Increase local snapshot frequency and check that new recovery points are created on the source
volume.
D. Improve replication bandwidth and packet loss, then check that the backlog drains and the required
RPO is met.
Answer: D.
Explanation:
The measurements point to a sustained network-throughput shortfall. Addressing WAN contention,
available bandwidth, and packet loss targets that bottleneck. The engineer must then confirm that the
backlog drains and replication meets the unchanged RPO.
6.In the documented PowerStore Gen 1/Gen 2 base-enclosure architecture, which component provides
the appliance's compute capability?
A. The drive carrier.
B. The power supply unit.
C. The node.
D. The midplane.
Answer: C.
Explanation:
The node contains the processors and memory used for appliance computation. A base enclosure
contains two nodes.
7.An engineer skipped VMware integration during initial configuration and is now connecting a
PowerStore cluster to vCenter through PowerStore Manager. No previous vCenter connection exists.
6 / 10
The approved accounts are vc-integrator, a vCenter account with the required vCenter privileges, and
ps-vasa, a PowerStore account with VM Administrator privileges. Both accounts are valid. Network
access and certificate prerequisites have been verified.
Which credential assignment follows the documented Connect workflow?
A. Use vc-integrator for both vCenter Server Configuration and VASA Registration.
B. Use vc-integrator for vCenter Server Configuration and ps-vasa for VASA Registration.
C. Use ps-vasa for vCenter Server Configuration and vc-integrator for VASA Registration.
D. Use ps-vasa for both vCenter Server Configuration and VASA Registration.
Answer: B.
Explanation:
The vCenter connection fields require the vCenter user's credentials. The VASA Registration fields
require a PowerStore user with VM Administrator privileges. Connecting after initial configuration is
supported.
8.During the initial installation of a new PowerStore 1200T base enclosure with a supported NVMe
expansion enclosure, which prerequisite does the installation guide specify before powering on the base
enclosure?
A. Complete cabling of the expansion enclosure.
B. Register a vCenter Server connection.
C. Assign a snapshot policy to the first volume.
D. Complete host-volume mapping for a production host.
Answer: A.
Explanation:
When an expansion enclosure is part of the initial installation, its cabling must be completed before the
base enclosure is powered on. Connecting the base enclosure's power cables to an energized source
starts it automatically, so this prerequisite matters before that connection.
9.An engineer will add one uninitialized PowerStore 1200T to a healthy, single-appliance cluster. Both
appliances run the same approved PowerStoreOS 4.4 build. Model and deployment-mode compatibility,
management-network connectivity, credentials, and physical link health have been verified. Existing
production IP assignments must remain intact.
The engineer reviews the following configuration. The three rows shown are the entire management-
address pool currently available for the expansion workflow.
Resource Observed configuration
Management address 10.60.10.30 Unused
Management address 10.60.10.31 Unused
Management address 10.60.10.32 Assigned to an existing node
Existing appliance clustering link aggregation
Native VLAN 410; tagged VLANs 410 and 411
allowed
7 / 10
Resource Observed configuration
New appliance clustering link aggregation
Native VLAN 411; tagged VLANs 410 and 411
allowed
Switching between appliances
No translation between native VLANs 410 and
411
Which two changes address the unmet expansion prerequisites without disrupting the existing cluster?
Choose two answers.
A. Add at least one additional valid, unused management IP address to the expansion pool.
B. Permit tagged VLAN 410 on the new clustering links while retaining their native VLAN 411.
C. Align the new clustering links with the existing cluster's native VLAN 410 end to end.
D. Mark 10.60.10.32 as unused and allocate it to the new appliance.
E. Reinitialize the existing appliance so its assigned management addresses become available.
Answer: A and C.
Explanation:
Only two listed addresses are unused; expansion needs at least three. A supplies the missing address
without reusing a production assignment.
The clustering link aggregations must communicate on the same native VLAN. C aligns the new
appliance with the existing cluster. Merely allowing the same tagged VLANs does not establish the
required native-VLAN connectivity.
10.An engineer is validating infrastructure services for a new PowerStore T deployment. The
management IP configuration and routing are correct. The approved time server is 10.80.0.20; its
upstream clock and NTP service are healthy. The former time server at 10.80.0.10 no longer offers NTP.
The following are synthetic test observations, not appliance command output.
Test or configuration Observation
Configured NTP endpoint ntp.storage.example
DNS response used by the PowerStore nodes ntp.storage.example resolves to 10.80.0.10
Ping from the node management network to
10.80.0.20
Successful
NTP test from an authorized administration
workstation to 10.80.0.20
Valid UDP response received
Node NTP traffic sent directly to 10.80.0.20
during a diagnostic test
UDP request denied by the intervening firewall
Firewall rules for node management sources to
10.80.0.20
ICMP and TCP permitted; the observed NTP
UDP flow is denied
Which two changes together address the observed blockers before time-synchronization validation is
repeated? Choose two answers.
A. Retain the current endpoint because the approved server responds to ping.
8 / 10
B. Replace the configured NTP endpoint with the approved server's IP address, 10.80.0.20.
C. Add a rule permitting TCP to 10.80.0.20 while keeping the observed UDP flow denied.
D. Increase replication bandwidth while leaving the endpoint and firewall rules unchanged.
E. Permit the observed node-to-server NTP UDP flow and its return traffic through the firewall.
Answer: B and E.
Explanation:
The configured name directs requests to the retired server. B selects the approved server without
depending on that stale DNS result. A valid repair of the DNS record could also solve this endpoint
problem, but it is not offered among the choices.
E removes the independently observed UDP transport block. The workstation's successful test does not
prove that traffic from the PowerStore nodes is permitted.
11.An engineer is completing the Initial Configuration Wizard for a new, uninitialized PowerStore 1200T.
Hardware and networking prerequisites have been verified. This single appliance must provide iSCSI
volumes immediately and native NFS file storage next quarter. The customer will not approve factory
reinitialization after production data is loaded.
Which deployment choice meets the complete requirement?
A. Select Block Optimized now, then enable native NFS without changing the deployment mode.
B. Select Block Optimized now, then expose its vVol resources as native PowerStore NFS file storage.
C. Select Block Optimized now, then convert to Unified while the production configuration remains
online.
D. Select Unified now, retaining native file capability for the scheduled NFS workload.
Answer: D.
Explanation:
Unified supports both block and file resources. Selecting it during initial configuration accommodates the
planned NFS requirement while supporting the immediate iSCSI workload.
12.Match each observation to the PowerStore management interface the administrator is directly using.
Identify the administrator-facing interface, rather than a transport or API that another tool may use
internally.
Items
SourceID Observation
S1
The administrator runs the installed pstcli client in a terminal to manage
the cluster.
S2
An application sends an HTTPS management request using an HTTP
method and exchanges JSON directly with the cluster API.S3
The administrator uses PowerStore Manager's HTML5 web interface to
select Storage > Volumes.
Targets
- T1: PowerStore Manager graphical interface
- T2: PowerStore CLI
- T3: PowerStore REST API
9 / 10
Use each TargetID exactly once. Write a complete SourceID-to-TargetID mapping.
Answer: S1 → T2; S2 → T3; S3 → T1.
Explanation:
S1 names the installed command-line client, so its administrator-facing interface is PowerStore CLI. S2
describes direct HTTP/JSON interaction with the REST API. S3 explicitly uses the Manager web
interface and its navigation.
13.An engineer will move eligible storage resources from appliance A to appliance B within the same
PowerStore T cluster. Both appliances are healthy and compatible, capacity and migration workspace
are sufficient, and the engineer has the required privileges. Every mapped host is a supported Linux
host. None of the listed block resources is a boot-from-SAN volume or contains one. Existing host I/O
must remain available.
The following synthetic checks were completed. A “verified” path includes the applicable host
connectivity, registered initiators and host rescan. Resources are currently on A.

Which two resources are eligible to start the documented internal migration to B now? Choose two
answers.
A. VG-ORDERS
B. VOL-LOG
C. VOL-REPORT
D. VOL-IMPORT
E. FS-ARCHIVE
Answer: A and C.
Explanation:
The entire volume group VG-ORDERS and standalone volume VOL-REPORT are supported resource
types. Their mapped hosts have verified access to both appliances, and neither resource is in an active
import or migration session.

14.A PowerStore multiprotocol file system uses the Native access policy. A Linux application accesses it
through NFSv3 with AUTH_SYS; a Windows user accesses the same files through SMB. The engineer
collects these synthetic observations:
Check Result
NFS client and effective UNIX identity
Client 10.91.30.21; UID 2001, primary GID 2001; no
supplementary groups; credentials verified at the NAS
server
Client's NFS export access
Matching host entry allows Read/Write; export is
mounted and NFSv3 is enabled
Parent directories Search access permitted; no additional ACL restrictions
control.txt
Owner UID 2001, group GID 2001, mode 0600; the
application reads it successfully over NFS
dataset.csv
Owner UID 1001, group GID 1001, mode 0600; the
same application receives a permission denial when
reading it over the same NFS export
SMB access to dataset.csv
The Windows user's SMB ACL grants read access; an
actual SMB read succeeds
GID 2001 is an approved application-only group. The existing owner must retain read/write access, the
application's NFS identity must gain read access without write access, and other UNIX identities must
gain no access. Preserve the Native policy, export configuration and existing SMB ACL.
Which targeted change meets these constraints?
A. Change this client's export access to Read-Only, keeping dataset.csv's owner, group and mode
unchanged.
B. Change dataset.csv's owner to UID 2001, retaining group 1001, mode 0600 and the existing SMB
ACL.
C. Change dataset.csv's group to GID 2001 and mode to 0640, retaining owner UID 1001 and the
existing SMB ACL.
D. Change dataset.csv's mode to 0644, retaining its existing owner, group and SMB ACL.
Answer: C.
Explanation:
The successful control read rules out a general inability of this client to use the export. For dataset.csv,
the effective UID is not the owner, and mode 0600 grants no group or other access. Under Native, an
SMB ACL grant does not supply the NFS permission that is missing.
C keeps the owner's read/write bits, grants the application-only group read permission, and leaves
others with no permission. Its group-read bit is 0040, giving mode 0640 with the existing owner-
read/write bits. With no additional ACLs, changing this NFS permission set does not rewrite the separate
SMB ACL under Native. Retest both protocols and confirm that the application's NFS write attempt
remains denied.
