Huawei's end-to-end active-active data center solution is divided into six logical layers, namely, storage, computing, application, network, transmission, and security layers.
Which are key points in designing these layers? (Multiple Choice)

• A.The computing layer uses virtualization platforms such as FusionSphere and VMware to provide cross-data-center clustering, thereby enabling multiple mission-critical applications to run in active-active mode.
• B.The transmission layer employs optimization approaches such as dispersion compensation to ensure the minimum latency on the transmission layer.
• C.The storage layer uses the FastWrite function to reduce two round trips to one for each standard write I/O, thereby improving the write performance.
• D.The security layer uses Huawei USG series to provide security protection functions such as FW and IDS for data centers.

• A.Data in the snapshot volume is the same as that in the source volume at 09:10 am.
• B.Data in the snapshot volume is the incremental data generated during 9:00 am to 9:10 am in the source volume.
• C.Data in the snapshot volume is the same as that in the source volume at 9:00 am,
• D.The snapshot volume is a physical copy of the source volume generated at 9:00 am.
