(Choose four)

  A. Use Elastic Load Balancer (ELB) for load distribution, setting backend server weights so that under normal conditions, 100% of traffic is directed to the production center; in case of disaster, 100% of traffic is switched to the disaster recovery center.
  B. Synchronize web services and application servers using the Storage Disaster Recovery Service (SDRS).
  C. Deploy RDS in primary/standby mode across AZs, enabling cross-AZ data synchronization.
  D. Use Intelligent DNS to control traffic routing so that under normal conditions, 100% of user traffic is directed to the production center, and in case of a failure, 100% of traffic is switched to the disaster recovery center.

• Question 353:

  When using HUAWEI CLOUD Object Storage Migration Service (OMS) to migrate data, the migration is listed in lexicographical order by default according to the selected prefix. Whether newly added data can be migrated successfully during the migration process depends on whether the migration task has completed the listing of related objects when they were added.

• Question 354:

  When a large healthcare company deploys some of its services on HUAWEI CLOUD, the public VPC needs to connect to the offline data center through VPN or Direct Connect. Which of the following descriptions about VPN and Direct Connect are correct? (Choose four)

  A. Considering performance, you can use Direct Connect because it provides a high-speed, low-latency, stable, and secure dedicated connection channel.
  B. Considering cost, you can use VPN because it is inexpensive, fast to deploy, and encrypts transmitted data.
  C. Considering redundancy, multiple private network connections (tunnels) can be configured to achieve mutual redundancy, allowing VPN and leased lines to back up each other.
  D. Considering redundancy, mutual redundancy can also be achieved through multiple private network tunnels, supporting multi-line redundancy for private connections.

  A. True
  B. False
  A. True

• Question 356:

  A company initially used ECS services at the beginning of its cloud migration. However, due to recent security compliance checks, the company was required not to deploy its business on the same physical host as non-corporate businesses. Therefore, the company decided to migrate its business to DeH (Dedicated Host).

  Which of the following methods can be used to migrate ECS services to DeH? (Choose three)

  A. Create a private image of the original ECS, release it in DeH, and migrate the content in the ECS to DeH through the SMS Migration Tool.
  B. Purchase data migration services from the HUAWEI CLOUD Marketplace for migration.
  C. On the ECS page, select Migrate ECS from the More options menu to migrate the ECS instance to DeH.

• Question 357:

  Data Express Service (DES) is a massive data transmission solution that supports terabyte- to petabyte-level data migration to the cloud. During the data migration process, the data transmitted by DES is stored in which of the following cloud services?

  A. HUAWEI Cloud Disk
  B. Elastic File Service (SFS)
  C. Cloud Disk (EVS)
  D. Object Storage Service (OBS)

• Question 358:

  A large enterprise is planning to migrate its entire internal business system to HUAWEI CLOUD to reduce overall IT procurement and operational costs. In terms of security, the company has two requirements:

  Administrators frequently travel and need to perform secure remote operations from multiple locations.

  Multiple subsystems are used independently by different departments, and network isolation between subsystems is required.

  Which of the following solutions can meet the company's needs? (Choose four)

  A. Enable the VPN Tunnel service, allowing administrators to use VPN-encrypted communication during operation and maintenance.
  B. Create multiple ECS instances under a VPC to install subsystems used by different departments, assign only private IP addresses to all ECS instances, and place them in unique security groups.
  C. Establish a separate bastion host for remote login and OandM, and authorize the bastion host to access other subsystem ECS instances.
  D. Use the security group function in the VPC to place ECS instances running different subsystems into dedicated security groups.
