Zorluk: KolayRoute 53 Routing Policies and DNS Failover Strategies

A solutions architect is configuring an active-passive disaster recovery (DR) strategy for a simple web application using Amazon Route 53. The primary endpoint is located in the us-east-1 Region, and the secondary backup endpoint is located in the us-west-2 Region. Which two configurations are required to set up this active-passive failover? (Select TWO.)

  1. Create a primary failover record pointing to the primary endpoint in us-east-1 and associate a Route 53 health check with itCevap
  2. Create a secondary failover record pointing to the secondary endpoint in us-west-2Cevap
  3. C
    Create latency routing records pointing to both endpoints to handle failover based on the lowest network latency
  4. D
    Associate a Route 53 health check directly with an RDS read replica in the secondary Region to automatically promote it to primary
  5. E
    Configure the secondary failover record with an automated action to boot and scale up the backup EC2 instances upon failover detection

Cevap

To configure Route 53 active-passive failover, you must create a primary failover record pointing to the primary endpoint in us-east-1 and associate a Route 53 health check with it, and also create a secondary failover record pointing to the secondary endpoint in us-west-2.
For an active-passive failover configuration, a primary failover record pointing to the primary endpoint must be created and linked to a Route 53 health check. This health check monitors the primary site. A secondary failover record pointing to the standby endpoint must also be configured. When the health check determines the primary site is down, Route 53 stops sending traffic to the primary record and starts resolving queries to the secondary record.

Adım Adım Çözüm

1
Identify the primary active endpoint and the backup standby endpoint for the disaster recovery strategy.
The primary active endpoint is in us-east-1, and the secondary standby endpoint is in us-west-2.
This establishes the active-passive relationship where all normal traffic goes to us-east-1, and traffic only switches to us-west-2 during a disaster.
2
Create and configure a primary failover record in Route 53.
A record pointing to the us-east-1 endpoint with its routing policy set to Failover and failover type set to Primary, associated with a Route 53 health check.
Route 53 needs a health check associated with the primary record to monitor its availability and determine when to trigger failover.
3
Create and configure a secondary failover record in Route 53.
A record pointing to the us-west-2 endpoint with its routing policy set to Failover and failover type set to Secondary.
This record serves as the backup target. Route 53 only resolves queries to this record when the primary endpoint is determined to be unhealthy.
