Question 581

Colleagues customized Huawei's primary and backup disaster recovery solutions for customers.

Customers have already selected one set of OceanStor 2600TV2 and one set of third In the storage system of the third party, the two sets of equipment are placed in two data centers to implement the main and backup disaster recovery.

This solution:

Not feasible. Huawei's active and standby disaster recovery solution requires at least a storage system of OceanStor5600 V3 and above to be realized.

Feasible, Huawei's active and standby disaster recovery solution can support the connection of OceanStor 2600T V2 equipment and third-party arrays.

Not feasible. Huawei's active and standby disaster recovery solution requires at least one OceanStor V3 storage system to be implemented.

Question 583

A disaster recovery project adopts the single-choice solution of Huawei's network layer complete space snapshot method, and starts to create a snapshot of the source volume at 9:00, 9:

The snapshot is created at 10 o'clock. During this process, the source volume is being written. Which of the following statements is correct?

The data content of the snapshot volume is the same as the data content of the source volume at 9:00.

The data content of the snapshot volume is the same as the data content of the source volume at 9:10.

The data content of the snapshot volume is the incremental data of the source volume between 9:00 and 3:10.

The snapshot volume is a physical copy of the source volume at 9:00.

Question 586

Which of the following statements about the deployment of Huawei's active-active data center is correct: (multiple choice)

The storage layer does not support one of the heterogeneous takeover of third-party storage, and then use the LUN structure after the takeover and the LUN on the other V3 Create a HyperMetro LUN.

Deploy at least two independent GSLBs at each site at the network layer to achieve load balancing between sites.

When deploying arbitration, the software supports installation on physical servers or virtual machines. The arbitration server uses the IP network to connect to the active-active data Two sets of storage arrays of the heart.

The transmission layer adopts Huawei OptiX OSN series DWDM, and each site deploys 2 sets of WDM equipment.

Question 588

A colleague is working on a dual-active disaster recovery plan. By testing the arbitration server to the storage system at both ends, the bandwidth is 4Mbit/s, and the delay is 4Mbit/s. RTT=40ms, and packet loss rate=1%, then this scheme:

Not feasible, because the active-active disaster tolerance bandwidth must not be less than 10Mbit/s.

Feasible, because it meets the conditions of the active-active disaster recovery plan.

Not feasible, because the packet loss rate of active-active disaster recovery must be =0.1%.

Not feasible, because the delay of active-active disaster recovery RTT=120ms
