Dell EMC D-PSC-MN-01 Exam - Topic 3 Question 21 Discussion

Actual exam question for Dell EMC's D-PSC-MN-01 exam

Question #: 21
Topic #: 3

A platform engineer is tasked with adding F600 nodes to an existing Dell EMC PowerScale cluster. After racking and stacking the F600 nodes, they determine that the cluster contains X210 and H400 nodes.

What should the platform engineer consider?

AH400 nodes cannot co-exist with the F600 nodes in the same cluster

BThe F600 must use InfiniBand for internal network communication

CF600 nodes cannot co-exist with X210 nodes in the same cluster

DThe cluster must be upgraded to Ethernet back-end topology

Show Suggested Answer

Suggested Answer: D

Adding F600 nodes to an existing cluster requires compatibility in back-end networking.

Key Considerations:

Back-End Networking:

F600 Nodes: Use Ethernet for internal communication.

Existing Nodes (X210 and H400): May be using InfiniBand.

Action Required:

Upgrade the cluster's back-end to Ethernet topology to accommodate F600 nodes.

Why Other Options Are Incorrect:

Option A: H400 nodes can coexist with F600 nodes if back-end networking is compatible.

Option B: F600 nodes do not use InfiniBand.

Option C: F600 nodes can coexist with X210 nodes with the appropriate back-end network.

I agree, but B seems important too. InfiniBand is key for F600.

I think option A is crucial. H400 and F600 can't mix.

D seems a bit extreme, can't we just stick with what we have?

Definitely option D. Upgrading the cluster to Ethernet back-end topology is the way to go. InfiniBand is so last decade!

I'm not sure about that. Shouldn't the platform engineer consider the network topology and ensure compatibility between the different node types?

I believe the cluster might need an upgrade for the back-end topology, but I'm not confident if that's a requirement for adding F600 nodes.

I vaguely remember that F600 nodes have some limitations with other node types, but I can't remember if it's X210 or H400 that they can't coexist with.

I practiced a similar question where we had to consider network communication types. I feel like InfiniBand is important for F600 nodes, but I can't recall the specifics.

Hmm, this is a tricky one. I'm not entirely sure about the compatibility between the different node types. I'll need to review the documentation and potentially consult with a subject matter expert to make sure I select the right answer.

I've got a good feeling about this one. Based on my experience with Dell EMC PowerScale, I believe the correct answer is C. The F600 nodes cannot co-exist with the X210 nodes in the same cluster. I'll double-check the details, but I'm confident in this approach.

Okay, let's think this through step-by-step. The question is asking what the platform engineer should consider when adding F600 nodes to an existing cluster with X210 and H400 nodes. I'll need to analyze each option and see which one best addresses the compatibility concerns.

Option C seems correct, as the question states that the cluster contains X210 and H400 nodes, and the F600 nodes cannot co-exist with the X210 nodes.

Option B is the way to go. InfiniBand is the future, and the F600 nodes will need it for optimal performance. Ethernet is so 2000s.

I'm not sure about this one. The question seems to be testing our knowledge of Dell EMC PowerScale cluster compatibility. I'll need to review the specifications for the different node types to determine the correct answer.
