Hitachi Vantara HQT-4420 Exam - Topic 1 Question 11 Discussion

Actual exam question for Hitachi Vantara's HQT-4420 exam

Question #: 11
Topic #: 1

In the event of a SAN-attached G10 node failure, which LUN configuration will maintain access to a given set of data LUNs?

AData Protection Level 2

BHCP LUN replicator

CZero Copy Failover

DDynamic multi-pathing

Show Suggested Answer

Suggested Answer: A, C

When performing a six-drive upgrade on an HCP G10 with local storage:

RAID level and Virtual Disks will be created automatically (A): This is correct. The system automatically handles the RAID configuration and creation of virtual disks to ensure that the new drives are correctly integrated into the existing storage structure.

The node is online during this procedure (C): This is also correct. The upgrade can be performed while the node remains online, minimizing disruption to the system's operation and ensuring continuous availability. These procedures are documented in the 'HCP G10 Maintenance and Upgrade Guide,' which outlines the steps for online upgrades and automatic RAID configuration.

Data Protection Level 2? Not sure that’s enough for failover.

Zero Copy Failover sounds interesting, but does it really work?

I think HCP LUN replicator is the way to go.

Dynamic multi-pathing is key for access!

Dynamic multi-pathing seems like it could help with access during a node failure, but I’m not confident if it’s the best choice here.

Zero Copy Failover sounds familiar, but I can't recall if it's specifically for SAN failures or just general failover.

I feel like we practiced a question similar to this, and I think HCP LUN replicator was mentioned as a good option for redundancy.

I think I remember something about Data Protection Level 2 being important for maintaining access, but I'm not entirely sure.

I think the answer is C - Zero Copy Failover. That sounds like the best way to maintain access to the data LUNs if a node fails. I'm fairly confident in that, but I'll double-check the details just to be sure.

I'm a bit confused by the terminology in this question. Can someone explain what a "SAN-attached G10 node" is and how that relates to the LUN configuration options? I want to make sure I fully understand the context.

Okay, let's see. I'm pretty sure the key here is understanding how the different data protection and failover mechanisms work. I'll need to carefully consider each option.

Hmm, this seems like a tricky one. I'll need to think through the different LUN configuration options and how they relate to maintaining access in a node failure scenario.

Okay, I think I've got this. The key is to minimize federal estate taxes while ensuring the wife gets the income and the sons get the remaining assets. I'll go with option C - bypass trust plus QTIP trust.
