Dell EMC D-PST-MN-A-24 Dell PowerStore Maintenance Achievement Exam Practice Test

Answer : D

The correct description of the SAS cabling when adding an expansion enclosure to a Dell EMC PowerStore, for each node and expansion enclosure side, is Option D: SAS cabling goes from existing A ports to new B ports. At the last enclosure, SAS cabling returns from the A ports to the alternate node's B ports.

When adding a SAS expansion enclosure to a Dell EMC PowerStore system, the cabling must be done in a specific manner to ensure proper connectivity and performance.

The SAS cabling should start from the existing A ports on the base enclosure and connect to the new B ports on the expansion enclosure1.

At the last expansion enclosure in the chain, the SAS cabling should return from the A ports back to the B ports on the alternate node1.

This cabling method ensures that each node is connected to each expansion enclosure and that the enclosures are daisy-chained correctly for optimal performance and redundancy1.

For detailed cabling instructions and diagrams, it is recommended to consult the Dell PowerStore Installation and Service Guide or contact Dell EMC support for assistance.

Answer : B

The reason for the best practice of leaving 2 Us of space at the bottom of the rack when racking Dell EMC PowerStore systems is to leave room for serviceability.

When installing a Dell EMC PowerStore system, it is recommended to leave 2 Us of space at the bottom of the rack.

This space is not for cooling, wheel clearance, or stability, but rather to ensure that there is enough room for service activities1.

Serviceability involves the ability to access and maintain hardware components easily. The additional space allows for better maneuverability and access to the system for maintenance and repairs.

Following this best practice helps in preventing potential issues that might arise from cramped spaces, which can make it difficult to perform necessary service tasks1.

For more detailed information on installation best practices, refer to the Dell EMC PowerStore Quick Start Guide or the Best Practices Guide21.

Answer : D

When the error ''-bash: pstcli: command not found'' appears after running a PSTCLI command on a Linux host, it typically means that the shell cannot locate the pstcli executable in the directories listed in the PATH environment variable. To resolve this issue, the installation directory of pstcli needs to be added to the PATH variable. This can be done by editing the shell initialization file (such as .bashrc or .bash_profile for Bash shell) and appending the installation directory to the PATH variable.

Here are the steps to resolve the problem:

Locate the installation directory of PSTCLI. If you followed the default installation, it should be in /opt/dellemc/pstcli-version/bin/.

Open the shell initialization file in a text editor. For example, if using Bash, you might edit ~/.bashrc or ~/.bash_profile.

Add the following line to the file: export PATH=$PATH:/opt/dellemc/pstcli-version/bin/. Replace /opt/dellemc/pstcli-version/bin/ with the actual installation directory if it is different.

Save the file and reload the shell configuration by running source ~/.bashrc or source ~/.bash_profile, or simply close and reopen the terminal.

Verify that pstcli can be found by running echo $PATH and ensuring the directory is listed.

Try running the pstcli command again to confirm that the issue is resolved.

By adding the PSTCLI installation directory to the PATH variable, the shell will be able to locate the pstcli executable when the command is run1. It is important to ensure that the PATH variable is correctly set to include all necessary directories for command-line tools to function properly. If the issue persists, it may be necessary to check the installation of PSTCLI or consult the Dell EMC PowerStore documentation for further troubleshooting steps1.

Answer : B

This command is used to inject a temporary root access key into the Dell EMC Data Domain system, allowing the storage administrator to have root access to perform the necessary tasks.

Based on the documentation and available commands for storage administrators, this is the appropriate command for the described scenario.

Answer : C

A data collection in Dell EMC PowerStore Manager can be initiated from the cluster, appliance, and alerts sections within the PowerStore Manager user interface. This process is essential for gathering system logs and other information that can be used for troubleshooting or analysis.

To initiate a data collection, follow these steps:

Log into the PowerStore Manager user interface.

Navigate to the 'Settings' menu.

Go to the 'Support' section.

Select 'Gather Support Materials'.

Choose the scope of the data collection, which can be at the cluster level, for a specific appliance, or related to certain alerts.

Click the 'Gather Support Materials' button to start the collection process.

Monitor the progress in the 'Jobs' section of PowerStore Manager or within the 'Support Materials' section1.

It is important to note that the data collection process may take some time to complete, depending on the amount of data and the system's performance. Once the data collection is finished, the gathered materials can be used by Dell EMC support for further analysis or can be reviewed by the storage administrator to address any issues1. For more detailed instructions on data collection, refer to the Dell EMC PowerStore documentation or the support knowledge base articles provided by Dell23. Following these guidelines ensures that the data is collected correctly and efficiently.

Answer : D

When the license expiration date is within a week, Dell PowerStore generates a warning-level alert. This alert severity level is used to indicate that action should be taken soon to prevent potential service disruptions or limitations on system functionality. A warning alert is not as severe as a major alert, which would indicate immediate attention is required, but it is more critical than an informational alert, which is typically used for general notifications without immediate impact.

The warning alert serves as a proactive reminder to renew or update the license to ensure continuous operation of the PowerStore system. It is important to address these alerts promptly to maintain access to all features and avoid any limitations on system management operations1.

For more information on alert severities and license management in Dell PowerStore, administrators can refer to the PowerStore documentation on License State Alerts and the PowerStore Manager Overview, which provide detailed explanations of the different alert levels and the steps to manage and resolve licensing issues23. Following the guidelines in these documents will help ensure that the storage system remains fully operational and compliant with licensing requirements.

Answer : B

The protocol used for the storage network in Dell PowerStore systems is Fibre Channel (FC). FC is a high-speed network technology primarily used for storage networking. Dell PowerStore utilizes FC as part of its all-NVMe design, which also includes NVMe-over-fabric networking to deliver low latency performance for storage workloads1.

Fibre Channel provides several benefits for storage networks, including:

High throughput and low latency for storage operations.

Support for long-distance networking, which is beneficial for disaster recovery and remote backups.

A mature and widely supported ecosystem with a variety of hardware and software options.

For detailed information on configuring and using FC with Dell PowerStore, administrators should refer to the Dell PowerStore Networking Guide for Storage Services and the Dell PowerStore Best Practices Guide. These documents provide comprehensive instructions on network configurations, including best practices for setting up and managing FC networks within Dell PowerStore environments23. Following these guidelines ensures optimal performance and reliability of the storage network.
