A company is using Route 53 for a web application that experiences sudden traffic spikes. They want to ensure that DNS responses are fast and that the application can handle the load. What should they do?

Use a high TTL value to reduce the number of DNS queries.

Use a traffic flow policy to route traffic based on health checks.

Use an alias record to an Amazon CloudFront distribution.

Use a low TTL value for the record to allow quick changes during traffic spikes.

A company runs a web application on EC2 instances in two AWS regions. They want to distribute traffic evenly between the two regions, but they also want to automatically stop sending traffic to a region if its health check fails. They use Route 53. What should they do?

Create a failover routing policy with one region as primary and the other as secondary.

Create a geolocation routing policy with health checks for both regions.

Create a latency-based routing policy with health checks for both regions.

Create a weighted routing policy with equal weights for both regions and associate health checks with each record.

A financial services company is required to protect its public DNS zone from DNS spoofing and cache poisoning. They use Amazon Route 53 as their DNS provider. What should they do to meet this requirement?

Use Route 53 Resolver DNS Firewall to block malicious domains.

Enable DNSSEC signing on the hosted zone and configure the domain registrar to use the DS records.

Create a traffic flow policy to route traffic based on health checks.

Enable logging on the hosted zone and send logs to CloudWatch Logs.
