Dell EMC Exam D-UN-DY-23 Topic 9 Question 15 Discussion

Actual exam question for Dell EMC's D-UN-DY-23 exam

Question #: 15
Topic #: 9

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?

ATwo iSCSI target interfaces must be configured with IP addresses from separate subnets.

BAny single host should connect to any single array using one protocol only.

CA connection must be established between the host iSCSI initiators and Unity iSCSI targets before provisioning the new LUN.

Show Suggested Answer

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.

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?

A: Option C is definitely important. You need that connection in place before adding a new LUN.

Wait, so we have FC HBAs already connected to the storage array, and now we want to set up iSCSI as well? That sounds a bit overkill, don't you think?

I'm not sure about option A. I think option C might be the correct answer because establishing a connection between the host initiators and Unity targets seems like a necessary step before provisioning the new LUN.

I agree with Lelia. Having separate subnets for the iSCSI target interfaces ensures better network segmentation and avoids any potential issues with routing.

I think option B is the correct answer. Using only one protocol per host is a best practice to simplify management and troubleshooting.

But wouldn't it be better to establish the connection first before provisioning the new LUN?
