EMC Dell PowerScale Maintenance Exam Sample Questions (Q45-Q50):

NEW QUESTION # 45
What status is an engineer trying to test if they run the isi_hwmon -scommand?

  • A. DIMM
  • B. Sensor
  • C. CPU
  • D. Battery
  • E. System

Answer: B

Explanation:
The command isi_hwmon -s is used on Dell PowerScale systems to display the status of various hardware sensorswithin a node. This command helps engineers monitor and test the operational status of different sensors that report on hardware conditions such as temperature, voltage, fan speeds, and other critical environmental parameters.
* Purpose of isi_hwmon Command:
* The isi_hwmon utility is a hardware monitoring tool specific to Dell PowerScale (formerly Isilon) systems.
* It provides real-time data and status of hardware components via sensors.
* Understanding the -s Option:
* The -s flag with isi_hwmon stands for "sensors."
* Running isi_hwmon -s lists the current readings and status of all hardware sensors in the node.
* This includes temperature sensors, voltage sensors, fan speed sensors, and more.
* Use Cases:
* Monitoring System Health:
* Engineers use this command to ensure that all hardware components are operating within normal parameters.
* Troubleshooting:
* Helps in diagnosing issues related to overheating, power supply fluctuations, or fan failures.
* Preventive Maintenance:
* Regular checks can prevent hardware failures by identifying abnormal readings early.
* Sample Output:
* The command outputs a list of sensors along with their current readings and status indicators (e.
g., OK, Warning, Critical).
* Why Other Options Are Incorrect:
* A. DIMM:
* While isi_hwmon can display information about memory modules, the -s option specifically targets sensors, not DIMMs directly.
* C. CPU:
* CPU status may be part of sensor readings (like temperature), but the command focuses on sensors rather than the CPU as a standalone component.
* D. Battery:
* Battery status can be monitored, but again, it falls under the umbrella of sensor data.
* E. System:
* The term "System" is too broad; isi_hwmon -s specifically targets sensor data.
Dell PowerScale References:
* Dell EMC PowerScale OneFS Command-Line Reference Guide:
* Provides detailed information on the isi_hwmon command and its options.
* Dell EMC PowerScale OneFS Administration Guide:
* Discusses hardware monitoring and the importance of sensor data in maintaining system health.
* Knowledge Base Articles:
* Articles detailing how to interpret sensor data and troubleshoot hardware issues using isi_hwmon.


NEW QUESTION # 46
What security mechanism is used in the OneFS API to encrypt communications?

  • A. SED
  • B. OpenSSH
  • C. HTTPS
  • D. RBAC

Answer: C

Explanation:
The OneFS API usesHTTPS(HyperText Transfer Protocol Secure) to encrypt communications, ensuring secure data transfer between clients and the PowerScale cluster.
* OneFS API and Security:
* OneFS API:
* Provides a RESTful interface for programmatically managing and interacting with the PowerScale cluster.
* Security Importance:
* Protects sensitive data and configuration information transmitted via the API.
* Use of HTTPS:
* Encryption:
* HTTPS uses TLS (Transport Layer Security) to encrypt data in transit.
* Prevents eavesdropping and man-in-the-middle attacks.
* Authentication:
* Supports certificate-based authentication to verify the identity of the server.
* Standard Protocol:
* Widely accepted and supported for secure web communications.
* Why Other Options Are Less Suitable:
* Option A (SED):
* Self-Encrypting Drives (SEDs) encrypt data at rest, not communications.
* Option B (RBAC):
* Role-Based Access Control (RBAC) manages user permissions and authorization, not encryption.
* Option D (OpenSSH):
* OpenSSH provides secure shell access, not used for the OneFS API communications.
* Implementing HTTPS with OneFS API:
* Default Behavior:
* OneFS API endpoints are accessed via HTTPS by default on port 8080 or 8080.
* Certificate Management:
* Administrators can install custom SSL certificates to ensure secure connections.
* API Calls:
* Applications interacting with the OneFS API must support HTTPS requests.
Dell PowerScale References:
* Dell EMC PowerScale OneFS API Reference Guide:
* Details on API usage and security considerations.
* Dell EMC PowerScale OneFS API Reference Guide
* Dell EMC PowerScale OneFS Security Configuration Guide:
* Provides information on configuring HTTPS and managing certificates.
* Dell EMC PowerScale OneFS Security Guide
* Knowledge Base Articles:
* Article ID 000123006:"Securing OneFS API Communications with HTTPS"
* Article ID 000123007:"Configuring SSL Certificates for OneFS API Access"


NEW QUESTION # 47
What is the required minimum number of PowerScale P100 and Bl 00 Accelerator nodes to add to a PowerScale cluster?

  • A. 0
  • B. 1
  • C. 2
  • D. 3

Answer: C

Explanation:
The required minimum number of Dell PowerScaleP100andB100accelerator nodes that can be added to a PowerScale cluster is2.
* Understanding Accelerator Nodes:
* P100 and B100 Nodes:
* TheP100(Performance Accelerator) andB100(Backup Accelerator) nodes are designed to enhance specific functionalities within a PowerScale cluster.
* P100nodes improve performance by providing additional CPU and RAM resources.
* B100nodes are used to accelerate backup operations.
* Minimum Node Requirements:
* High Availability:
* Dell PowerScale requires a minimum oftwo accelerator nodesto ensure high availability and redundancy.
* If one node fails, the other can continue to provide services without interruption.
* Cluster Integration:
* Adding at least two nodes allows the cluster to distribute workloads effectively and maintain balanced performance.
* Dell PowerScale Best Practices:
* Fault Tolerance:
* Deploying a minimum of two nodes prevents a single point of failure.
* Scalability:
* Starting with two nodes allows for future expansion as performance or capacity needs grow.
* Why Other Options Are Incorrect:
* Option B (4):
* Four nodes exceed the minimum requirement; while acceptable, they are not the minimum.
* Option C (1):
* A single node does not provide redundancy or high availability.
* Option D (3):
* Three nodes also exceed the minimum requirement.
Dell PowerScale References:
* Dell EMC PowerScale Network Design Considerations:
* Outlines the requirements for deploying accelerator nodes.
* Dell EMC PowerScale Network Design Considerations
* Dell EMC PowerScale OneFS Administration Guide:
* Provides information on node types and deployment best practices.

* Knowledge Base Articles:
* Article ID 000123001:"Minimum Requirements for Adding Accelerator Nodes to PowerScale Clusters"


NEW QUESTION # 48
When maintaining Customer Replaceable Units (CRUs) in a PowerScale node, what is important to ensure?

  • A. The cluster is in maintenance mode.
  • B. Proper static electricity discharge procedures are followed.
  • C. All CRUs are tested individually before installation.
  • D. The firmware is updated post-installation.

Answer: B


NEW QUESTION # 49
A platform engineer has created a cluster of 8 F200 nodes. A requirement is for each power supply on each node to supply power to the respective node equally.
What must the platform engineer do to meet the requirement?

  • A. Use the iDRAC settings on each node to disable the hot spare feature
  • B. Cable each node power connection to a different PDU in the rack
  • C. Run the isi config and change the settings in the config subsystem
  • D. Run the isi set -n command to change the power supply behavior

Answer: A

Explanation:
By default, the Power Supply Hot Spare feature may cause one power supply to run while the other is idle.
Steps to Ensure Equal Power Supply Loading:
* Access iDRAC Interface:
* Log into the iDRAC for each F200 node.
* Disable Hot Spare Feature:
* Navigate to Power Management settings.
* Disable the Power Supply Hot Spare option.
* Result:
* Both power supplies will share the load equally.
Dell PowerScale References:
* Dell EMC PowerScale F200 Hardware Guide:
* Power Supply Configuration:
* Instructions on adjusting power supply settings via iDRAC.
* Best Practices:
* Ensure redundancy by connecting power supplies to separate PDUs.
* Monitor power usage to confirm balanced loading.
