Select all that apply.

• A

  When the production site fails, switch the primary and standby database status, and modify DNS resolution so that traffic distribution is 0% to the production site and 100% to the disaster recovery site.

• B

  Configurations, logs, snapshots, and backups generated by the production and disaster recovery centers are synchronized across regions through VBS (Volume Backup Service).

• C

  Service sharing between the two regions can be achieved through DNS, and the disaster recovery center only handles services in the event of a disaster.

• D

  When an AZ failure occurs at the production site, the business system switches to another AZ, and the database performs an active/standby switchover.

• E

  Deploy RDS DB instances in both the production and disaster recovery centers, where the database maintains a 1:1:1 relationship and supports active-standby mode.
