A. Volume recovery is fast: no data relocation is required, and the volume is restored from the snapshot recovery 1S (the traditional SAN is at the hour level).

B. Theoretically supports unlimited snapshots.

C. FusionStorage snapshot mechanism saves the user volume data at a certain point in time and can be used to export data and restore data.

D. FusionStorage snapshot data uses the ROW (Redirect-On-Write) mechanism during storage. The snapshot does not cause the performance of the original volume to decrease.

A. In order to meet the requirements of Level 3 of information security, all types of security devices must be deployed. For example, NGFW, Anti-DDoS, IPS, CIS, LogCenter, UMA, etc. must be deployed.

B. IDS is usually deployed side by side in the data center, because it is considered to avoid single point of failure, and it is also considered that the direct path deployment will cause all traffic to be detected by the device and cause network delay.

C. Because the firewall is a comprehensive device that combines IPS and anti-virus capabilities, you can replace all IPS devices with NGFW to save costs.

D. The degree of network security in the data center depends mainly on the performance of the equipment and the security capabilities of the vendors. Therefore, careful consideration should be given to product procurement.

A. Business-driven -> Service Assurance -> Service Sustainability Improvement -> Service Recovery

B. Service Assurance -> Service Recovery -> Service Sustainability Improvement -> Business-driven

C. Service Recovery -> Service Assurance -> Service Sustainability Improvement -> Business-driven

D. Service Sustainability Improvement -> Service Assurance -> Service Recovery -> Business-driven

A. MDC

B. FusionStorage Agent

C. OSD

D. FusionStorage Manager

A. Cloud platform creates a router.

B. The virtual router is automatically generated on AC-DCN.

C. The physical device sends and receives VPC configurations.

D. The cloud platform creates a VPC.

A. System performance will be improved through Session persistence management.

B. Through Session persistence, each application server re-creates and maintains the session information, which can avoid the loss of the session as much as possible.

C. Session persistence management means that all subsequent requests from the customer are distributed to the same application server.

D. An HTTP Session is a series of requests that a user makes to the server on the same browser.

A. Manage network

B. Cloud platform management domain

C. Storage domain

D. Copy the network
