Dell EMC Dell PowerMax Operate v.2 D-PVM-OE-01 Exam Practice Test

Answer : A

We need to create a secure snapshot named 'Stor1' from the storage group 'StorGroup1' in the Unisphere for PowerMax simulator, and the snapshot should be protected from deletion for two days.

Here's a step-by-step guide on how to do this, based on typical Unisphere functionality:

Steps:

1. Launch the Simulator and Navigate to the Storage Groups Section

Open Unisphere for PowerMax in your web browser.

Log in to the simulator (you should already be logged in with the array SID 1762 selected).

In the left-hand navigation pane, click on Storage and then select Storage Groups.

2. Locate and Select 'StorGroup1'

In the Storage Groups view, you'll see a list of all storage groups on the array.

Find the storage group named 'StorGroup1'.

Click on the name 'StorGroup1' to open its details view.

3. Initiate the Snapshot Creation Process

Within the 'StorGroup1' details view, look for an option related to creating snapshots or protecting the storage group. This might be a button labeled:

'Protect'

'Create Snapshot'

'SnapVX'

Or an icon representing snapshot creation.

Click the appropriate button or icon to start the snapshot creation process.

4. Configure Snapshot Settings

A new window or panel will appear, allowing you to configure the snapshot settings.

Snapshot Name: Enter Stor1 as the snapshot name.

Snapshot Technology: Select SnapVX (or a similar option) as the snapshot technology.

Secure Snapshot: This is crucial. Look for an option labeled 'Secure Snapshot,' 'Enable Secure Snap,' 'Secure Snap,' or something similar. Check this option.

Retention/Expiration: You need to set the retention period for the secure snapshot. This will define how long the snapshot cannot be deleted. There are usually a few ways to configure this:

Expiration Time: Set an explicit expiration date and time that is two days from now.

Retention Period: Specify a retention period of 2 days.

No Expiry: This option is not what we want here. We want the snap to be secure for 2 days.

Choose the appropriate option to make the snapshot undeletable for two days.

Other Settings: Review any other available settings. You might be able to choose between creating a new snapshot or linking to an existing one. Select the option to create a new snapshot.

5. Create the Snapshot

After configuring all the snapshot settings, review them carefully to ensure they are correct.

Click the button to create the snapshot. This button might be labeled:

'Run Now'

'OK'

'Create'

'Finish'

6. Verify Snapshot Creation (Optional)

After the snapshot creation operation completes, you can verify that the snapshot was created successfully:

Go back to the 'StorGroup1' details view.

Look for a tab or section related to snapshots (e.g., 'Snapshots,' 'TimeFinder,' 'Local Replication').

You should see the 'Stor1' snapshot listed there, and its status should indicate that it's a secure snapshot with the correct retention period (2 days).

Answer : D

The storsrvd daemon is a critical component of the Solutions Enabler (SYMCLI) software suite used to manage Dell PowerMax and VMAX storage arrays. Its primary function is to:

Listen for SYMAPI Sessions: It acts as a communication endpoint, listening for incoming SYMAPI sessions from clients or management tools like Unisphere.

Handle Management Requests: When a client connects, storsrvd receives and processes SYMAPI commands and requests, forwarding them to the appropriate components within Solutions Enabler for execution.

Essentially, storsrvd acts as an intermediary between SYMCLI clients and the storage array, facilitating communication and management operations.

Why other options are incorrect:

A . Manages Composite Groups and Device Groups: This is handled by other components within Solutions Enabler.

B . Provides centralized gatekeeper device management: While storsrvd plays a role in device management, it's not the sole component responsible for it.

C . Provides replication consistency protection: This is a function of SRDF (Symmetrix Remote Data Facility) and related components.

Non-Disruptive Migration (NDM) is a feature in PowerMax that allows you to migrate data between storage arrays without any downtime or disruption to host applications. During NDM, SRDF (Symmetrix Remote Data Facility) is used to replicate data between the source and target arrays. Here are the configuration rules that apply to SRDF groups and connections during NDM:

A . The source and target arrays are at most one hop away from the control host: The control host, which manages the NDM process, must have direct connectivity to both the source and target arrays. This ensures efficient communication and control during the migration.

E . DM RDF groups are configured with a minimum of one path: SRDF groups used for NDM (DM RDF groups) must have at least one active path between the source and target arrays. This ensures that data can be replicated continuously during the migration.

Why other options are incorrect:

B . Two DM RDF groups are created per SG migration session: This is not a strict requirement. The number of DM RDF groups may vary depending on the configuration and the specific NDM operation.

C . RF and RE ports are supported, with RF ports being selected if both types are available: While RF and RE ports are supported for SRDF, there's no specific preference for RF ports during NDM. The choice of ports depends on the overall network configuration and availability.

D . A single array cannot have multiple DM RDF groups: An array can have multiple DM RDF groups if needed for different NDM operations or configurations.

Unisphere for PowerMax offers different deployment options to manage PowerMax storage arrays. Based on the exhibit, we can identify the following:

Separate SYMAPI Server: The diagram shows a dedicated SYMAPI server. SYMAPI (Symmetrix Application Programming Interface) is a command-line interface used to manage PowerMax and VMAX storage arrays. This indicates that the Unisphere server is not directly connected to the storage arrays.

Unisphere Server Connected to SYMAPI Server: The Unisphere server is shown to be connected to the SYMAPI server. This means that the Unisphere server relies on the SYMAPI server to communicate with the PowerMax arrays.

No Direct Connection to Arrays: The Unisphere server does not have a direct connection to the PowerMax arrays.

Considering these points, the deployment option depicted in the exhibit is a remote deployment. In a remote deployment, the Unisphere server is installed on a separate host and communicates with the PowerMax arrays through a SYMAPI server. This allows for centralized management of multiple arrays from a single Unisphere instance.

Why other options are incorrect:

A . Embedded: In an embedded deployment, the Unisphere software runs directly on the PowerMax array itself. This eliminates the need for a separate Unisphere server.

B . Either remote or local: While the diagram could technically represent a local deployment with a dedicated SYMAPI server, the presence of the separate SYMAPI server and the lack of direct connection to the arrays strongly suggest a remote deployment.

D . Local: In a local deployment, the Unisphere server is typically installed on the same host as Solutions Enabler, which has direct connectivity to the storage arrays.

A Gatekeeper in PowerMax is a small, dedicated device used for communication between the storage array and Solutions Enabler (SYMCLI), the command-line management interface. The default size of a Gatekeeper on a PowerMax array is 3 cylinders.

While the size can technically be specified in kilobytes (KB), the traditional and preferred unit for Gatekeeper size is cylinders. This is because cylinders represent a specific number of blocks on the physical disks, and using cylinders helps ensure consistent sizing across different disk types and configurations.

Why other options are incorrect:

A . 3 KB, C. 6 KB: These sizes are too small to be practical for a Gatekeeper.

Answer : C

The symsan command in Solutions Enabler is used for various SAN (Storage Area Network) management tasks. One of its functions is to scan the SAN environment to discover and verify the configuration of devices and paths.

When used in the context of an Open Replicator Migrator for Dell EMC (O-MDM) session, the symsan command specifically:

Verifies SAN Configuration: It checks the connectivity and configuration of the SAN fabric to ensure that the source and target devices are accessible and properly configured for the migration.

Non-Disruptive: It performs this verification without disrupting any applications or host I/O operations on the remote host. This is crucial for maintaining business continuity during the migration planning phase.

Why other options are incorrect:

A . Temporarily stops the remote application to verify the SAN configuration: symsan does not stop applications; it performs a non-disruptive scan.

B . Verifies the SAN configuration and creates an ORS session on the remote host: symsan only verifies the SAN; it doesn't create ORS (Open Replicator Solutions) sessions.

D . Temporarily stops the remote application and creates an ORS session: Again, symsan doesn't stop applications or create ORS sessions.

Okay, I understand. We need to perform a system health check and review the compliance status for a PowerMax array with SID ending in 1762 using the Unisphere simulator, then generate and download a compliance report.

Here's how you would do it in the Unisphere for PowerMax simulator, based on the provided image and common Unisphere functionality:

Steps:

1. Launch the Simulator and Access the System Health View

Open Unisphere for PowerMax in your web browser.

You should already be logged in to the simulator, with the PowerMax array with SID 1762.

The initial Overview page (as shown in the image) provides a good starting point for a health check.

2. Analyze the Overview Page

Health: The 'Health' section displays the overall health status of the array. In the image, it shows '100' with a green checkmark, which indicates that the array is currently healthy.

Alerts: The 'Alerts' section will show if there are any active alerts. In the image, it shows a green checkmark and 'All alerts have been acknowledged,' meaning no unacknowledged alerts. You can click 'View all Alerts' to see the alert history.

Capacity: The 'Capacity' section indicates whether storage resource pools are within their capacity thresholds. The green checkmark and 'All storage resource pools are within their capacity thresholds' message indicate that capacity is currently healthy. You can click 'View Report' for more details.

Performance: The 'Performance' section is not detailed in the image, but it would typically provide a quick overview of the array's performance.

Updates: The 'Updates' section shows the system's PowerMaxOS code level and whether any updates are overdue. In the image, it shows that the system is 'Up to Date.'

3. Navigate to the Compliance Section

In the left-hand navigation pane, click on Data Protection to expand it.

Click on Compliance under Data Protection.

4. Review Compliance Status

The Compliance view will show you the overall compliance status of your storage groups against the defined compliance policies.

Review the compliance status for each Storage Group.

Look for any storage groups that are marked as 'Non-Compliant.'

5. Generate the Compliance Report

Click on 'Generate Report' (or a similarly worded button) within the Compliance view. This might also be represented as an icon in the simulator.

Select all Storage Groups Since we need to generate the report for all storage groups.

Report Format: Choose the desired report format. Common options are usually PDF, CSV, or HTML. For this simulation, let's assume PDF is available and select it.

Download the Report: Once the report is generated, there will typically be a 'Download' or similar option to save the report to your local system. Click it to download the compliance report.

6. Further Health Checks (Optional):

Detailed Performance Metrics: You can navigate to the Performance section in the left navigation pane (under 'Dashboard') to view more detailed performance metrics for various components of the array.

Hardware Status: You can typically find a 'Hardware' section (or similarly named section) that provides information about the physical components of the array (e.g., DAEs, directors, ports).
