NEW QUESTION 9
To which bus is the Dell EMC Unity 880F DPE connected?

• A. 49
• B. 89
• C. 99

Answer: D

Explanation:
The DPE on 480/F, 680/F, and 880/F systems is internally connected to Bus 99 which is a separate bus than the first SAS expansion port that is connected to Bus 0. Therefore, the DPE is recognized by the system as Bus 99 Enclosure 0 while the first DAE connected to the first SAS expansion port would be Bus 0 Enclosure 0. This is different than X00/F, X50F, and 380/F systems. Furthermore, this means that the twenty-five drives in front of the DPE for 480/F, 680/F, and 880/F systems are internally recognized as Bus 99 Enclosure 0 Drive 0 – Bus 99 Enclosure 0 Drive 24. In Unisphere, the drives are seen DPE Drive 0 –DPE Drive 24

What is a consequence of using an 800 GB drive and five 400 GB drives in a Dell EMC Unity XT dynamic pool?

• A. Extents 9 – 14 are used to create a RAID Group
• B. Unisphere short strokes the 800 GB drive to 8 extents
• C. Extents 9 – 14 are marked unavailable until more 800 GB drives are added
• D. Extents 9 – 14 are marked unavailable and can never be recovered

Answer: C

Explanation:
The entire capacity of a particular drive size is only available when the drive count within the drive partnership group for the drive in question matches or exceeds the stripe width plus one drive. It is not recommended to mix different size drives of the same type for this reason, unless an adequate number of drives are available to meet or exceed the stripe width plus one drive requirement
