Question 1

When setting Host I/O Limits on a Storage Group, what are the available dynamic I/O distribution modes?

Accepted Answer

A

Explanation: When configuring Host I/O Limits (a Quality of Service feature) for a Storage Group on a Dell EMC PowerMax array, there are three specific modes to control how the I/O limit is distributed across the front-end directors. These modes are: Never: The I/O limit is statically divided among the available front-end directors. The allocation does not change. OnFailure: The limit is statically divided, but if a director fails, its share of the I/O limit is dynamically redistributed among the remaining active directors. Always: The I/O limit is continuously and dynamically balanced across all active directors based on their real-time workload, ensuring optimal resource utilization.

Question 2

What are the two configuration rules that apply to SRDF groups and connections during Non- Disruptive Migrations'?

Accepted Answer

C, E

Explanation: During a Non-Disruptive Migration (NDM), specific SRDF groups, known as Data Migration (DM) RDF groups, are automatically created to manage the data transfer. The configuration of these groups and their underlying connections follows specific rules. NDM supports both Fibre Channel (RF) and GigE (RE) director ports for SRDF connectivity. However, if both port types are available between the source and target arrays, the NDM process will prioritize and select the RF ports, typically due to their lower latency and higher performance. Furthermore, for replication to occur, it is a fundamental requirement that each automatically configured DM RDF group must have at least one valid and operational path between the arrays.

Question 3

A systems administrator plans to use Non-Disruptive Migration (NDM) to migrate data (rom a VMAX array running Enginuity 5876 to a PowerMax running PowerMaxOS 5978 Which NDM mode is used?

Accepted Answer

B

Explanation: Non-Disruptive Migration (NDM) establishes a temporary SRDF relationship between the source VMAX (Enginuity 5876) and the target PowerMax (PowerMaxOS 5978). During the copy phase NDM forces that SRDF link to run in Adaptive Copy Disk (ACD) mode so the entire source device is copied in the background without host impact and without the write-latency requirements of synchronous mode. Once the adaptive-copy transfer is complete, the pairs are briefly switched to synchronous for cut-over, but the NDM “mode” that characterises the migration process is Adaptive Copy.

Question 4

What function does the storsrvd daemon support?

Accepted Answer

D

Explanation: The storsrvd daemon is the core Dell EMC Solutions Enabler server process. Its primary function is to run on a management host and listen on a designated TCP/IP port for incoming connections from SYMAPI clients. These clients can be local or remote symcli commands or any application built using the SYMAPI library. Once a session is established, storsrvd receives, authenticates, and processes these management requests, forwarding them to the appropriate PowerMax/VMAX storage array for execution. It acts as the central service broker for all SYMAPI-based storage management activities.

Question 5

DRAG DROP Place the steps to create a snapshot in Unisphere for PowerMax in the correct order https://kxbjsyuhceggsyvxdkof.supabase.co/storage/v1/object/public/file-images/Dell_EMC_D-PVM-OE-01/page_36_img_1.jpg

Accepted Answer

Explanation: The correct sequence outlines the logical workflow within the Unisphere for PowerMax GUI to create a secure snapshot of a storage group. The process begins by navigating to the specific storage group that needs protection. The "Protect" action initiates a wizard, where the user first selects the snapshot technology (SnapVX). Subsequently, the user configures the snapshot's basic and advanced settings, such as enabling Secure Snaps. The final step in any wizard-driven process is to review the summary of selected options and then execute the job either immediately or by scheduling it.

Question 6

DRAG DROP Place the steps to set Host Flags using the Create Host wizard in the correct order

Accepted Answer

Explanation: To configure Host Flags, the administrator must follow the hierarchical workflow of the Unisphere interface: Context: First, the specific storage array must be selected from the system dashboard or selector to ensure the configuration applies to the correct appliance. Navigation: Next, the user accesses the host management view by selecting Hosts from the main menu, followed by the Hosts object/option within that category. Action: The Create button is clicked to launch the "Create Host" wizard. Configuration: Finally, within the wizard (typically in the Initiator or Attributes step), the user clicks the Set Host Flags button. This opens the settings to override default port flags (e.g., enabling SC3 or SPC2 bits) required for the host's operating system.

Question 7

DRAG DROP Place the steps in the correct order for performing a Non-Disruptive Migration https://kxbjsyuhceggsyvxdkof.supabase.co/storage/v1/object/public/file-images/Dell_EMC_D-PVM-OE-01/page_6_img_1.jpg

Accepted Answer

Explanation: The correct sequence follows the standard lifecycle of a storage migration project. The process begins with preparation , which involves setting up the migration environment (e.g., zoning, connectivity) and then creating the specific migration session where source storage is discovered and target storage is provisioned. The execution phase follows, where data is synchronized in the background, followed by a non-disruptive cutover that redirects host I/O to the new array. Once the cutover is complete and validated, the migration is finalized by committing the changes, which makes the move permanent. Finally, the cleanup phase involves removing the now-redundant migration infrastructure.

Question 8

SIMULATION A company is setting up a multi-tenant environment where multiple departments share the same storage array with SID 1762. The IT department requires 2 TB of storage to be available on the ESXi1 host. Use "ESXi1_SG" for the storage group name, create a port group with Dir- Ports "OR-1C:0 and OR-2C:0," and leave all other settings at their default. Using the simulator, provision the storage required with a single volume using auto-provisioning groups.

Accepted Answer

SEE THE

Explanation: The "Provision Storage" wizard in Unisphere for PowerMax is the standard, automated method for provisioning storage to a host. This process correctly follows the requirements by creating a single 2 TB volume and placing it in a new storage group named ESXi1SG. It then creates a new port group with the specified director ports. Finally, the wizard automatically creates a masking view, which is the essential construct that links the storage group (what), the initiator group (who), and the port group (where) to grant the ESXi1 host access to the newly created volume.

Question 9

SIMULATION A customer has an existing host with two 100 GB volumes that are assigned from existing PowerMax storage. They would like to add three additional volumes of 100 GB each and change the service level that is assigned to the storage group from Gold to Platinum to support the current application SLO requirements.

Accepted Answer

SEE THE

Explanation: The scenario requires modifying an existing storage group to add three new volumes and change its Service Level. The provided image displays the final "Summary" screen of the "Modify Storage Group" wizard within Unisphere for PowerMax. This screen appears after the administrator has configured all the required changes: increasing the volume count from two to five (adding three new 100 GB volumes) and changing the Service Level from Gold to Platinum. To commit these changes and have the system execute the provisioning task, the final step is to click the "Run Now" button. This action submits the job to the PowerMax array.

Question 10

SIMULATION The web application server web_host_1 is deprecated. Remove all resources associated with the host to clean up the environment. Using the simulator, complete the task.

Accepted Answer

SEE THE

Explanation: To remove a deprecated host and its associated resources from the PowerProtect Data Manager environment, the correct procedure is to delete the asset from the inventory. The Infrastructure > Assets page provides the interface to manage all discovered resources. Selecting the specific application host (webhost1) and using the "Delete" action unregisters it from the system. Note that an asset cannot be deleted if it is currently included in a protection policy; it must be removed from the policy first. This action effectively cleans up the environment as requested.
