Actual exam question for Dell EMC's D-UN-DY-23 exam
Question #: 15
Topic #: 9
[All D-UN-DY-23 Questions]

A company has an ESXi host installed with FC HBAs that is connected to a Dell Unity XT storage array. A 500 GB LUN is provisioned to this host from the Unity array and is in production. The VMware administrator has configured a new vSwitch with the NICs on the server intended for iSCSI traffic. The storage administrator is asked to configure software iSCSI and provision a new 1 TB LUN from the storage array using iSCSI.

What is a consideration when satisfying this request?

Suggested Answer: B

The maximum number of drives on a traditional RAID group depends on the RAID type and the drive type. For RAID 5 and RAID 6, the maximum number of drives is 16 for all drive types.For RAID 1/0, the maximum number of drives is 32 for SAS and NL-SAS drives, and 16 for SSD drives.Reference: Dell EMC Unity: Best Practices Guide2, page 17.

Seems like a lot of setup for just one LUN.

I think option B sounds right, but I’m not completely confident. It seems like a common practice to stick to one protocol for a host and array.

I feel like we discussed the importance of having multiple iSCSI target interfaces, but I can't recall if they need to be on separate subnets.

I'm not entirely sure, but I think there was a practice question about using different protocols for the same host and array. Could that apply?

I remember something about needing to establish connections between initiators and targets before provisioning. That might be important here.

Good point, Silvana. I'm leaning towards A as well. We need to make sure the iSCSI interfaces are on separate subnets to ensure proper connectivity.

Hmm, I'm not sure about that. Wouldn't we also need to consider the subnet configuration for the iSCSI interfaces? I think A might be the right answer.

Okay, let's think this through step-by-step. We need to configure the iSCSI connection between the host and the storage array, and then provision the new LUN.

Hmm, I'm a bit confused here. The file is on the user's desktop, so I'm not sure if changing the access rights is the right solution. Maybe we need to look into a more dynamic way to locate the file.

If the attachment point is 130% of $2,000,000, that might be $2,600,000, so it seems like we'd need to factor that into what Longview actually pays.

A good strategy here would be to think through some real-world cloud scenarios and how a successful attack could impact multiple consumers. That should help me arrive at the right answer.

Ah, the age-old question of FC vs. iSCSI. It's like the battle of the storage protocols - may the best one win! Or maybe they can just hold hands and share the storage, who knows?

I'm going with B. Mixing protocols is like trying to speak French and Spanish at the same time - it's just gonna end in a linguistic disaster.

Option C seems like the way to go. Gotta establish that connection first before you can provision the new LUN. Otherwise, it's just not gonna work, right?
