正解：D
解説：
TheHeadroom graphin SANtricity System Manager shows the remaining performance capability of the physical objects (e.g., disks, SSDs) in the storage system.
This helps in understanding how much additional load the system can handle before reaching its performance limits.
References: NetApp SANtricity System Manager User Guide, which explains the performance monitoring features.

- B. /opt/multipath/multipath.cnf
- C. /etc/kernel/mp.conf
- D. /etc/multipath.conf
正解：D
解説：
The multipath configuration file for Fibre Channel (FC) on Linux systems is typically/etc/multipath.conf.
This file is used to define multipath settings and policies, such as path grouping, path selection, and failover behavior.
References: NetApp E-Series SANtricity Multipath Drivers Guide for Linux.
質問 # 31
You need to run a command from the SANtricity System Manager GUI to mark drives as native by using the CLI tool on an E-Series system that is running System Manager 11.60 or higher.
In this scenario, where would you locate this tool?
- A. Settings -> System -> Addons
- B. Support -> Support Center -> Diagnostics
- C. Modify Existing Storage
- D. Help -> CLI Command Reference
正解：A
質問 # 32
The out-of-band connection is an Ethernet connection from the storage manager host to the LAN, and from the LAN to which location?
- A. port 1 of the controller
- B. port 2 of the ESM
- C. port E of the controller
- D. port 1 of the I/O host
正解：A
質問 # 33
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
正解：C
解説：
* 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.
質問 # 34
You are adding drives to an existing Dynamic Disk Pool (DDP).
In this scenario, which two drive characteristics should you consider when selecting the drives? (Choose two.)

- B. if the drives are the same capacity or larger
- C. if the drives are from the same manufacturer
- D. if the drives have the same firmware level
正解：A、B
解説：
* Check Drive Capacity:
* Step:Ensure that the new drives are of the same capacity or larger than the existing drives in the DDP.
* Reason:Consistent drive capacity ensures optimal performance and utilization.
質問 # 35

質問 # 36
A junior administrator recently made changes to an E-Series system. As a result of these changes, the management host lost the ability to manage the E-Series system through in-band management, but the host still has access to the E-Series data volumes.
In this scenario, what caused this issue?
- A. The ownership of the management host's volumes changed
- B. The access volume was un-mapped
- C. Auto Load Balancing was disabled
- D. The management IPs were changed
正解：B
解説：
If the management host loses the ability to manage the E-Series system through in-band management but still has access to data volumes, the most likely cause is thatthe access volume was un-mapped. The access volume is crucial for in-band management as it provides a path for management commands.
In-band management relies on this special volume to communicate management commands between the host and the storage system. If the access volume is un-mapped, the management interface on the host will no longer be able to send these commands, even though data volumes remain accessible.
