Topic 3
  • PowerScale Hardware Maintenance: Targeted at system administrators, this section focuses on key tasks involved in maintaining PowerScale hardware. It examines candidates' proficiency in completing initial maintenance steps, preparing nodes for operation, and processing Field Replaceable Unit (FRU) and Customer Replaceable Unit (CRU) requests.
Topic 4
  • PowerScale Implementation: Geared towards cluster administrators, this section covers the practical aspects of implementing PowerScale systems. It focuses on creating new clusters, integrating nodes into existing clusters, and applying alternative configurations or accessories to improve performance.

EMC Dell PowerScale Maintenance Exam Sample Questions (Q116-Q121):

NEW QUESTION # 116
When joining a new node to a cluster, why is reformatting or reimaging often required?

  • A. To ensure the node's OS is compatible with the cluster
  • B. To update the node's firmware to the latest version
  • C. To remove any residual data from previous deployments
  • D. To configure the node with the cluster-specific settings

Answer: C


NEW QUESTION # 117
A platform engineer is building a new Dell EMC PowerScale cluster. The configuration wizard prompts to configure int-a.
What is a consideration when configuring int-a?

  • A. Must use the same subnet as groupnet0, subnet0.
  • B. Must be on the same subnet as int-b.
  • C. Must use the same subnet as node 1, ext-1.
  • D. Must be on a separate subnet from int-b.

Answer: D

Explanation:
In a Dell EMC PowerScale cluster, int-a and int-b are internal network interfaces used for back-end communication between nodes. Proper configuration of these interfaces is essential for cluster performance and redundancy.
Considerations:
* Separate Subnets for int-a and int-b:
* Assigning int-a and int-b to separate subnets enhances network redundancy.
* If one subnet experiences issues, the other can continue to handle internal traffic.
* Not on the Same Subnet:
* Placing both interfaces on the same subnet can create a single point of failure.
* It may also cause network conflicts and degrade performance.
Key Points:
* Network Isolation: Separating int-a and int-b ensures that internal communications are robust and fault- tolerant.
* Performance Optimization: This configuration allows for load balancing of internal traffic.
Dell PowerScale References:
* Dell EMC PowerScale OneFS Network Configuration Guide:
* Internal Network Configurationsection recommends using separate subnets for int-a and int-b.
* Explains the benefits of network redundancy and performance.
* Best Practices:
* Plan IP addressing schemes that allocate different subnets for internal interfaces.
* Document network configurations for troubleshooting and maintenance.


NEW QUESTION # 118
Which cluster interface provides the most detailed network traffic statistics and enables file and directory operations on the cluster?

  • A. Platform API
  • B. CLI
  • C. Web console
  • D. Serial console

Answer: B

Explanation:
The Command Line Interface (CLI) provides the most comprehensive and detailed interaction with a Dell PowerScale cluster. Through the CLI, administrators have access to a wide range of commands that offer detailed network traffic statistics, system performance metrics, and the ability to perform granular file and directory operations.
While the Web console offers a user-friendly graphical interface for cluster management, it may not provide the same level of detail or the full set of functionalities available in the CLI. The Serial console is primarily used for initial setup or troubleshooting when network access is unavailable. The Platform API allows for programmatic access but requires additional development effort to utilize.
The CLI is accessible via SSH and provides tools like isi statistics for detailed performance metrics and isi commands for file system operations. This makes it the most powerful interface for administrators needing in- depth information and control over the cluster.

NEW QUESTION # 119
An SSD has failed in Node 1 in a Dell EMC PowerScale F200 cluster. After replacing the drive, which command should be run to ensure the node has finished updating?

  • A. Isi devices device list -node-Inn 1
  • B. Isi status -q
  • C. Isi status -h
  • D. Isi devices -d

Answer: A

Explanation:
After replacing a failed SSD in Node 1 of a Dell EMC PowerScale F200 cluster, it's important to verify that the node has recognized the new drive and has finished any necessary updates or rebuild processes.
Command to Verify Device Status:
* isi devices device list --node-lnn 1:
* This command lists all devices (drives) associated with Node 1.
* It provides detailed information about each device, including status, health, and activity.
Why Option C is Correct:
* Specific to Node 1:
* The --node-lnn 1 parameter targets Node 1 directly.
* Comprehensive Output:
* The device list subcommand displays the status of all devices on the node.
* Verification of Update Completion:
* By reviewing the output, you can confirm that the new SSD is recognized and that any rebuild or update processes have completed successfully.
Why Other Options Are Less Appropriate:
* Option A (isi devices -d):
* This command is incomplete and may not provide the necessary information.
* Option B (isi status -h):
* Provides a high-level cluster status but does not detail individual device statuses.
* Option D (isi status -q):
* Gives a quick summary of cluster status, similar to Option B.
Dell PowerScale References:
* Dell EMC PowerScale OneFS CLI Administration Guide:
* Section on isi devices Commands:
* Explains how to use isi devices device list to view detailed device information.
* Provides options to filter by node, device type, and status.
* Steps to Verify Drive Replacement:
* Run the Command:
bash
Copy code
# isi devices device list --node-lnn 1
* Review Output:
* Look for the new SSD in the list.
* Check that the status is HEALTHY or OK.
* Confirm Rebuild Completion:
* Ensure that there are no active jobs related to data protection or rebuilds.
* Use isi job status to check for running jobs.
* Best Practices:
* After Replacing a Drive:
* Monitor the cluster for any alerts or errors.
* Ensure that data protection levels are restored.
* Documentation:
* Record the replacement in maintenance logs.
* Update any asset tracking systems with the new drive's details.
Additional Commands:
* Check Cluster Health:
arduino
Copy code
# isi status
* List All Devices:
arduino
Copy code
# isi devices list
By using the isi devices device list --node-lnn 1 command, the platform engineer can confidently confirm that Node 1 has recognized the new SSD and that all necessary updates have been completed.


NEW QUESTION # 120
What is the recommended action if a PowerScale node reports inconsistent data?

  • A. Remove the node from the cluster and replace it
  • B. Isolate the node immediately and perform a data integrity scan
  • C. Run a synchronization process with other nodes
  • D. Reboot the node to clear any temporary issues

Answer: B
