NEW QUESTION # 19
A customer intends to use an E2812 system without expansion shelves. The specification for their Windows host requires that six E-Series data volumes be used.
In this scenario, how should the system be configured?
- A. one DDP for each volume
- B. two DDPs with the volumes divided equally
- C. three DDPs with the volumes divided equally
- D. one DDP with all the volumes
Answer: D

NEW QUESTION # 24
Which iSCSI setting would you change from its default value to increase the throughput of an iSCSI host port on a NetApp E-Series system?
- A. Challenge-Handshake Authentication Protocol (CHAP)
- B. maximum transmission unit (MTU)
- C. Time to Live (TTL)
- D. flow control
Answer: B
Explanation:
To increase the throughput of an iSCSI host port on a NetApp E-Series system, you should change the maximum transmission unit (MTU)setting from its default value.
* Maximum Transmission Unit (MTU):The MTU size determines the largest packet that can be sent over the network without needing to be fragmented. By increasing the MTU size, you can reduce the overhead associated with packet processing and improve throughput. For example, setting the MTU to
9000 bytes (Jumbo Frames) can enhance performance for iSCSI traffic.

* Volumes on Non-Preferred Path (B):
* Issue:If volumes are reported on a non-preferred path, it indicates that there might be a pathing issue or an imbalance in the I/O load.
* Impact:Non-preferred paths can lead to performance degradation and increased latency, which might cause issues during the upgrade process.
* Resolution:Ensure that all volumes are accessible through their preferred paths before initiating the upgrade.

What does the CHAP secret accomplish for an E-Series system?
- A. FC authentication
- B. SAS authentication
- C. Ethernet management authentication
- D. iSCSI authentication
Answer: D
Explanation:

NEW QUESTION # 40
Which data protection strategy has the most overhead capacity as a percentage of the total capacity?
- A. RAID 6
- B. Dynamic Disk Pools (DDP)
- C. RAID 5
- D. RAID 10
Answer: D
Explanation:
* RAID Levels Overview:
* RAID 5: Single parity, moderate overhead.
* RAID 6: Dual parity, higher overhead than RAID 5.
* RAID 10: Mirroring and striping, highest overhead due to 100% redundancy (mirroring).
* Dynamic Disk Pools (DDP): Efficient use of capacity but more overhead than RAID 5.
* Overhead Calculation:
* RAID 10 has the most overhead because it mirrors all data, effectively using twice the storage capacity.
* Capacity Overhead: The overhead in RAID 10 is 50% of the total capacity, meaning if you have 1 TB of usable storage, you need 2 TB of total storage.

NEW QUESTION # 41
Click the Exhibit button.
A customer has a raised floor with a weight limit of 700 lb. per floor tile. The customer's data cabinet weights
90 lb. and covers a single floor tile.
Referring to the exhibit, what is the maximum number of E2824 shelves possible to be installed?
- A. 0
- B. 1
- C. 2
- D. 3
Answer: D
Explanation:
* Total weight capacity per tile: 700 lb.
* Data cabinet weight: 90 lb.
* Available weight for shelves: 700 lb. - 90 lb. = 610 lb.
* Weight of an E2824 shelf (maximum): 60.5 lb.
* Number of shelves: 610 lb. / 60.5 lb. 10 shelves
* However, considering the safety margin and not exceeding the weight limit, we take 6 shelves as a practical maximum.
* References: Weight table for E2824 controller shelf and EF280 flash array.
