Free Practice Questions for EMC D-PVM-OE-01 Exam

Step by Step Comprehensive Detailed Explanation:

The Dell VSI (Virtual Storage Integrator) vSphere plug-in is a tool that integrates Dell storage management capabilities into the VMware vSphere environment. It allows administrators to manage storage directly from the vSphere client. Within the "Configure Storage" section of the VSI plug-in, you can manage:  

Snapshots:The plug-in allows you to create, delete, and restore snapshots of virtual machines' storage volumes. This provides a convenient way to protect data and revert to previous states if needed.

Why other options are incorrect:

A. Remote replication:While PowerMax supports remote replication (SRDF), this is typically managed through Unisphere or Solutions Enabler, not the VSI plug-in.  

B. Port flags:Port configurations are usually handled through Unisphere or Solutions Enabler.

C. Access control:Access control and security settings are typically managed through Unisphere or other security tools.

We need to terminate a clone session for the storage group named "DATA" in the Unisphere for PowerMax simulator.

Here's a step-by-step guide on how to do this, based on typical Unisphere functionality and the context of the question:

Steps:

1. Launch the Simulator and Navigate to the TimeFinder/Clone 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, based on the provided image).

In the left-hand navigation pane, locate the section related to TimeFinder operations. This is usually found under:

Data Protection

Local Protection

TimeFinder

Expand the relevant sections and click onTimeFinder SnapVXorTimeFinder Clone(the exact wording might vary slightly in the simulator). The goal is to get to the view where you can manage clone sessions.

2. Locate the Clone Session for the "DATA" Storage Group

The TimeFinder/Clone view will display a list of existing clone sessions.

You need to find the session associated with the "DATA" storage group. Look for the following:

Storage Group Name:The "DATA" storage group should be listed as the source of the clone session.

Session Type/Mode:Verify that it's a Clone session (not a SnapVX snapshot or another type of session).

3. Select the Clone Session

Once you've found the correct clone session for the "DATA" storage group, select it.

You can usually do this by:

Clicking a checkbox next to the session.

Clicking on the session itself (if the interface allows it).

4. Terminate the Clone Session

After selecting the clone session, look for an action button or menu option to terminate it. This might be labeled:

"Terminate"

"Delete"

"Remove"

"Fracture"(in some older versions)

"Stop"

Click the appropriate button to initiate the termination process.

Confirmation:You will likely be prompted with a confirmation message to ensure you want to terminate the selected clone session. Verify that you have selected the correct session (the one for the "DATA" storage group) and confirm the termination.

Step by Step Comprehensive Detailed Explanation:

In SRDF (Symmetrix Remote Data Facility), an "update" operation refers to a specific process where changes made on the target (R2) side are copied back to the source (R1) side. This is typically used in disaster recovery scenarios where:

Failover:A failover occurs, and the target (R2) becomes the active production site.

Data Modification:Data is modified or updated on the target (R2) while it's acting as the primary.

Update Operation:An "update" is initiated to synchronize the changes from the target (R2) back to the source (R1), ensuring that the source has the latest data.

This process is crucial for maintaining data consistency and ensuring a smooth transition back to the original production site after a failover event.

Why other options are incorrect:

A. process to retain the data on the target R2 side:This is not specific to an "update" operation. Data retention on the target is a general aspect of SRDF.

B. A process used to return to the original production site after a failover event:While an "update" is part of the failback process, it's not the entire process itself. Failback involves other steps like reversing replication direction and restoring host access.

D. A process that allows separate hosts to access the same data independently:This describes a different SRDF configuration (like Active/Active) and is not related to the "update" operation.

Here's the correct sequence of steps along with explanations:

Correct Order:

Select Data Protection > Device Groups from the navigation pane.

Why:This is the starting point within Unisphere for PowerMax. You need to navigate to the section where device groups are managed and where TimeFinder operations are initiated.

Select a PowerMax array.

Why:In an environment with multiple PowerMax arrays, you must specify the array on which you want to create the clone copy sessions.

Select a group and click Create Pairs.

Why:You are selecting the specific device group that will be the source for the clone operation and choosing the "Create Pairs" action to initiate the clone session creation process. This implies you are creating a clone from an existing group of devices.

Select a source type and a target type.

Why:This step defines the characteristics of the source and target devices for the clone session. This could involve selecting from different storage groups, specifying thin or thick provisioning, or other relevant settings. Note that in a clone context, the "target type" often refers to how the clone will be linked to the source (e.g., a full copy or a linked target).

Click Run Now to run the operation.

Why:After configuring all the settings for the clone session, this action triggers the actual creation of the clone pairs based on the selected source and target types and other parameters.

Click the TimeFinder Clone tab to view the list of clones.

Why:Once the operation has been initiated, this is how you would verify that the clone sessions were created successfully and monitor their status.

Select Data Protection > Device Groups from the navigation pane.

Select a PowerMax array.

Select a group and click Create Pairs.

Select a source type and a target type.

Click Run Now to run the operation.

Click the TimeFinder Clone tab to view the list of clones.

Step by Step Comprehensive Detailed Explanation:

The Dell PowerMax 2500 is a mid-range storage array designed for enterprise environments. It offers a balance of performance, capacity, and scalability.  

Scalability:The PowerMax 2500 scales from a single node pair to a maximum of two node pairs. This allows for increased performance and capacity as needed. Each node pair provides processing power, cache memory, and connectivity.

Why other options are incorrect:

A. Supports up to 16 nodes:This is incorrect. The PowerMax 8500, the higher-end model, supports up to 16 nodes.

B. Supports up to 15 PB of effective capacity:While the PowerMax 2500 offers significant capacity, its maximum effective capacity is lower than 15 PB.

D. Uses Storage Class Memory:Both the PowerMax 2500 and 8500 utilize Storage Class Memory (SCM) for enhanced performance.
