Dell EMC D-PST-DY-23 Exam Questions Instant Access

Question 1

Which two statements are true regarding host group configurations? (Choose two.)

AAllows mixed protocol type hosts within the same host group.

BMaps volumes to all hosts in the host group.

CAllows mapping volumes to individual hosts in the host group.

DVolume-related operations are made across all hosts in the group.

Answer : B, D

Operations like snapshots, replication, or volume resizing affect all hosts in the group because the volume is shared across them. This ensures consistency and simplifies management in clustered or shared-storage environments.

Question 2

Which network does the PowerStore use for communication to the cluster database?

AStorage

BManagement

CICM

DICD

Answer : C

Question 3

SIMULATION

You're absolutely right! I apologize for my previous response. I can definitely try to extract the text from the image.

Here's the "Task" as written in the image:

A storage administrator must provision local storage resources for his database as per the below requirements:

Create a new "Database" storage resource as a capacity of 5TB

PowerStore under load must prioritize this workload

ESXi host called "ESXi3" is using iSCSI connectivity

The ESXi host must use the LUN number of 101

Use the simulator to make this configuration change.

ASee explanation below

Answer : A

1. Create the Host

Navigate to Compute > Hosts.

Click Add Host.

Enter the host name: ESXi3

Select iSCSI as the protocol.

Click Next.

Select the appropriate Network and Port Group for iSCSI connectivity.

Click Add.

2. Create the Volume

Navigate to Storage > Volumes.

Click Add Volume.

Enter the volume name: SQL_Datastore

Set the volume size to 5 TB.

Important: Under 'Advanced Settings,' locate the 'Performance' section and set the Workload Type to Database. This will prioritize the volume's performance for database operations.

Click Add.

3. Map the Volume to the Host

On the Volumes page, locate the newly created SQL_Datastore volume.

Click the More Actions button (three vertical dots) and select Map to Host.

Choose the ESXi3 host.

Important: In the 'LUN ID' field, enter 101 to assign the desired LUN number.

Click Map.

Verification

After completing these steps, go back to the Hosts page and select ESXi3.

Click the Volumes tab to confirm that the SQL_Datastore volume is mapped to the host with the correct LUN ID (101).

Key Considerations

iSCSI Network Configuration: Ensure that your iSCSI network is properly configured with the necessary VLANs and IP addresses.

Host Connectivity: Make sure that the ESXi3 host has the correct iSCSI initiator configuration to connect to the PowerStore appliance.

By following these steps, you'll successfully provision the local storage resources for the database on your new ESXi host, meeting all the specified requirements.

Question 4

Which two methods would a customer use to migrate their legacy block thick and thin clones to PowerStore? (Choose two.)

AMirrorview

BVM Import

CNon-disruptive Import

DSAN Copy

EAgentless Import

Answer : C, E

Question 5

SIMULATION

Use the simulator to assign a protection policy to the virtual machine ''VM1''. Use the following settings:

Snapshots on Monday through Friday at 10:00 PM Eastern Time

Retention of 10 days

When you have finished, continue to the next question.

ASee the Explanation below for complete solution

Answer : A

Navigate to the virtual machine management section where VMs are listed, usually under the 'Compute' or 'VM' section.

Locate 'VM1' from the list of virtual machines.

Access the settings or properties of 'VM1'.

Look for the 'Protection' or 'Protection Policies' section within the VM settings.

Select the option to create a new policy or assign an existing one.

In the policy settings, configure the snapshot schedule:

Set the frequency to weekly on Monday, Tuesday, Wednesday, Thursday, and Friday.

Set the time to 10:00 PM Eastern Time.

Configure the retention period for the snapshots to be 10 days.

Save the policy and ensure it is correctly associated with 'VM1'.

Question 6

An administrator is connecting a Linux host to a PowerStore appliance and must know which storage network interface to use.

Which nvme subcommand should be used?

Aconnect

Bid-ccrl

Cattach-ns

Ddiscover

Answer : D

Understanding NVMe-oF and the nvme Utility

NVMe over Fabrics (NVMe-oF): This technology allows NVMe storage to be accessed over a network fabric, such as Ethernet or InfiniBand. It provides high performance and low latency for demanding applications. PowerStore supports NVMe-oF, enabling efficient connectivity for Linux hosts.

nvme Utility: Linux systems use the nvme command-line utility to manage and interact with NVMe devices, including those accessed over a network. This utility provides various subcommands for tasks like discovering targets, connecting to them, and managing namespaces.

Why nvme discover is Essential

Discovering NVMe-oF Targets: The nvme discover subcommand is crucial for identifying the available NVMe-oF targets (like your PowerStore appliance) on the network. It scans the network based on the specified parameters (transport type, address range) and returns information about the discovered targets.

Identifying Storage Network Interfaces: The output of nvme discover includes details about the target's network interfaces, such as their addresses, transport types (e.g., TCP, RDMA), and NQN (NVMe Qualified Name). This information is essential for the administrator to determine the correct network interface to use when connecting the Linux host to the PowerStore appliance.

Example Usage

Bash

nvme discover -t tcp -a 192.168.1.0/24

This command would discover NVMe-oF targets that are accessible over TCP within the specified subnet. The output might look something like this (simplified):

Discovery Log Number of Records 1, Generation counter 2

=====Discovery Log Entry 0======

trtype: TCP

adrfam: IPv4

treq: not specified

portid: 8009

trsvcid: 4420

subnqn: nqn.2014-08.org.nvmexpress:uuid:01234567-89ab-cdef-0123-456789abcdef

traddr: 192.168.1.10

This output shows the target's NQN, transport type (TCP), IP address (192.168.1.10), and the port used for communication (8009).

Dell PowerStore Reference

While the nvme discover command is a general Linux utility, here are some Dell PowerStore resources that provide context for connecting Linux hosts:

PowerStore Host Configuration Guide: This guide provides comprehensive information about configuring different types of hosts, including Linux hosts, to connect to PowerStore. It covers various connectivity options and best practices. You can find the latest version of this guide on the Dell Support site.

By using nvme discover, the administrator can gather the necessary information about the PowerStore appliance's network interfaces and ensure proper connectivity for the Linux host.

Question 7

Which two pieces of information are required to create a new remote system connection? (Choose two.)

AIP address of local system

BNetwork Latency

CIP address of remote system

DRemote PowerStore name

ERemote domain name

Answer : B, C

In the Add Remote System slide-out panel, configure the following fields:

- Remote system type - Select PowerStore.

- Management IP address

- Description (optional)

- Network latency
