質問 # 20
Which network option should be configured to provide the best iSCSI performance on a Dell Unity XT array?
- A. Single VLAN for all traffic
- B. Jumbo frames
- C. Disable flow control
- D. A iSCSI offload
正解：D
解説：
Explanation
iSCSI offload is a network option that can be configured to provide the best iSCSI performance on a Dell Unity XT array. This option offloads iSCSI processing to the network adapter card, reducing the load on the host CPU and improving performance. With iSCSI offload enabled, the network adapter card can handle iSCSI processing tasks such as packet segmentation and reassembly, reducing the CPU overhead associated with iSCSI operations. Other options such as using a single VLAN for all traffic, configuring jumbo frames and disabling flow control may also help to improve iSCSI performance but iSCSI offload would provide the best results. It is important to note that configuring jumbo frames could have a positive impact on performance, but it also depends on the network infrastructure and the NICs support for it. Disabling flow control could cause issues on congested networks, so it's important to test it before disabling it.
質問 # 21
An administrator wants to use NAS Server Mobility to move a NAS server from SPA to SPB on a Dell Unity system What consideration must they be aware of?
- A. The system must be in service mode to complete the move
- B. Any replication sessions must be in a paused state before starting the move
- C. NAS Server Mobility is no longer supported following a software update
- D. DNS configuration will be lost after the move
正解：B
解説：
Explanation
When using NAS Server Mobility to move a NAS server from SPA to SPB on a Dell Unity system, an administrator must be aware that any replication sessions must be in a paused state before starting the move.
This means that any data replication sessions that are configured for the NAS server must be temporarily stopped to avoid data inconsistencies or data loss during the move. Once the move is complete, the replication sessions can be resumed, and data replication will continue as normal. NAS Server Mobility is still supported by Dell Unity, so it's not a concern of the move. The system does not need to be in service mode to complete the move, and the DNS configuration won't be lost after the move, the administrator should make sure that the DNS entries for the NAS server are updated to reflect the new location.
質問 # 22

正解：C
質問 # 24
At what granularity are blocks deduplicated on a Dell EMC PowerStore array?
- A. 32 KB
- B. 4 KB
- C. 64 KB
- D. 8 KB
正解：B
解説：
https://www.delltechnologies.com/resources/en-us/asset/white-papers/products/storage/h18151-dell-emc-powerstore-data-efficiencies.pdf Deduplication uses algorithms to analyze, perform pattern detection, and attempts to store only a single instance of data. In general deduplication can work at the block, bit-level, or file level. In PowerStore, deduplication works at the block level at 4 KB granularity.
質問 # 25
