Hitachi Vantara HQT-4420 Exam - Topic 4 Question 17 Discussion

Posted by Claudio on Feb 07, 2025 at 08:03 AM

A customer is using a four-node HCP G10 cluster and they would like to upgrade to eight nodes.

Which two node models can be used to upgrade the cluster? (Choose two.)

Suggested Answer: A, C

For the HCP G10 SSD option:

Two SSD disks are installed at the rear of the server (A): This is correct. The SSDs in the HCP G10 server are typically installed at the rear of the server to provide fast access to critical system data, such as metadata and indexes.

Software RAID1 is used to mirror the disks (C): This statement is also correct. Software RAID1 provides mirroring of the SSD disks, ensuring redundancy and data protection in case of a disk failure. RAID1 is chosen for its simplicity and reliability in providing redundancy without requiring additional hardware. Details can be found in the 'HCP G10 Hardware Configuration and Maintenance Guide.'

S10 won't fit, just G10 and G11.

Wait, can G11 really work with G10 clusters?

Totally agree, G10 is compatible!

G10 and G11 are the right choices for the upgrade.

I’m leaning towards the G10 and G11 for the upgrade, but I wish I had reviewed more about the Compute Rack models.

I feel like the S10 might not work with the G10 cluster, but I can't recall the specifics.

I remember practicing a question about node upgrades, and I think the Compute Rack 210H was mentioned as a possible option.

I think the G10 nodes are definitely compatible since they’re from the same generation, but I’m not sure about the G11.

This seems pretty straightforward. Based on the information provided, I think the G11 and S10 node models are the two that can be used to upgrade the cluster from four to eight nodes. I'll double-check, but I'm feeling pretty good about those choices.

I'm a bit confused by the node model options. I'm not familiar with all of these models, so I'll need to do some quick research to understand the differences between them before I can confidently select the two correct answers.

Okay, let me think this through. The question says the current cluster is four nodes, and they want to upgrade to eight nodes. So I'll need to find two node models that can be used to expand the cluster from four to eight nodes.

Hmm, this looks like a straightforward question about upgrading an HCP cluster. I'll need to carefully review the node model options to determine the two correct answers.

Hold up, are we sure the Compute Rack 210H is not a valid option? I mean, it's a rack, so it could fit more nodes, right? *winks*

Yup, B) G10 and C) G11 are the ones. I wonder if the customer is looking to boost their storage capacity or just increase the processing power. Either way, those models should do the trick.
