EMC Dell PowerScale Maintenance Exam Sample Questions (Q85-Q90):

NEW QUESTION # 85
What is the rack size of an F600 node?

A. 1U
B. 4U
C. 3U
D. 2U

Answer: A

Explanation:
The Dell PowerScale F600 node occupies 1U of rack space. It is designed to provide high performance and density in a compact form factor, making it suitable for data centers with limited rack space.
* Dell PowerScale F600 Overview:
* Form Factor:The F600 is a 1U rack-mounted node.
* All-Flash Storage:Equipped with NVMe SSDs for high-speed data access.
* Performance:Ideal for workloads requiring low latency and high throughput.
* Rack Space Considerations:
* Efficient Use of Space:The 1U size allows for more nodes to be installed within a standard 42U rack.
* Scalability:Easy to scale out by adding additional 1U nodes to the cluster.
* Benefits of 1U Form Factor:
* Reduced Footprint:Saves physical space in the data center.
* Energy Efficiency:Lower power consumption per node compared to larger form factors.
* Cooling Efficiency:Easier to manage cooling requirements with smaller units.
Dell PowerScale References:
* Dell EMC PowerScale F600 Specification Sheet:
* Lists the physical dimensions, including the 1U rack height.
* Dell EMC PowerScale Technical Overview:
* Provides detailed information on the F600's architecture and benefits.
* Hardware Installation Guides:
* Offer instructions on installing the F600 node in a rack, confirming its 1U size.

NEW QUESTION # 86
Before a PowerScale node can be put into operation after maintenance, what is an essential task?

A. Performing a full system backup
B. Running a system health check
C. Restoring user data
D. Updating the node's firmware

Answer: B

NEW QUESTION # 87
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: D

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.
* Dell EMC PowerScale OneFS Administration Guide
* Knowledge Base Articles:
* Article ID 000123001:"Minimum Requirements for Adding Accelerator Nodes to PowerScale Clusters"

NEW QUESTION # 88
Which network configurations are valid on a Dell PowerScale Gen 6 cluster that uses an Ethernet backend?

A. IPv4 addressing only, 9000 MTU, and 24-bit subnet mask
B. IPv4 addressing only, 1500 MTU, and 48-bit subnet mask
C. IPv4 or IPv6 addressing, 1500 MTU, and 24-bit subnet mask
D. IPv6 addressing only, 1500 MTU, and 48-bit subnet mask

Answer: A

NEW QUESTION # 89
A Dell EMC PowerScale platform engineer is asked to reimage a node.
What should they check before they start the reimage process?

A. Customer has redundant paths to their data.
B. The treedelete job has been run against the node.
C. Node has been SmartFailed and removed from the cluster.
D. SyncIQ job has been run to copy the node data.

Answer: C

Explanation:
Reimaging a node in a Dell EMC PowerScale cluster is a significant operation that requires careful preparation to prevent data loss and maintain cluster integrity.
Pre-Reimage Checklist:
* SmartFail the Node:
* Initiate a SmartFail process to evacuate data from the node to other nodes in the cluster.
* Ensures that no data is lost during the reimage process.
* Remove Node from Cluster:
* After SmartFailing, the node should be properly removed from the cluster configuration.
* Prevents cluster confusion and potential conflicts.
Key Points:
* Data Protection:
* SmartFailing redistributes data, maintaining data protection policies.
* Critical for clusters that do not have full data redundancy.
* Operational Readiness:
* Verify that the cluster is healthy before proceeding.
* Check that there are sufficient resources to accommodate data migration.
Dell PowerScale References:
* Dell EMC PowerScale OneFS Administration Guide:
* Chapter on Node Removal and Replacementoutlines the steps for SmartFailing and reimaging.
* Data Protection Considerationsemphasizes the importance of SmartFailing.
* Best Practices:
* Monitor the SmartFail process to completion before starting reimage.
* Communicate with stakeholders about potential performance impacts during data evacuation.
