NEW QUESTION # 27
Click the Exhibit button.
A customer's host is running a Red Hat Enterprise Linux 7.6 server with dm-mp configured for ALUA and is connected to a single volume on the EF280 system that is shown in the exhibit.
In this scenario, how many active/optimized paths are available to the volume?
- A. 0
- B. 1
- C. 2
- D. 3
Answer: C
Explanation:
Based on the exhibit provided and the scenario where a Red Hat Enterprise Linux 7.6 server is configured with Device Mapper Multipathing (dm-mp) for Asymmetric Logical Unit Access (ALUA) and connected to a single volume on the EF280 system, there are4 active/optimized pathsavailable to the volume.
In ALUA configurations, paths are classified as active/optimized or active/non-optimized. Each controller on the EF280 system will have two active/optimized paths to the volume, leading to a total of four such paths.
This setup ensures high availability and optimal performance for data access.

NEW QUESTION # 35
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. Time to Live (TTL)
- C. flow control
- D. maximum transmission unit (MTU)
Answer: D
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.
