Which AWS service is used for DNS and domain name management?
a) Amazon Route 53
b) Amazon VPC
c) AWS Direct Connect
d) Amazon SNS
Answer:
a) Amazon Route 53
Explanation:
Amazon Route 53 is a scalable Domain Name System (DNS) web service that provides reliable domain name registration, DNS routing, and health checking. It connects user requests to applications running on AWS, such as EC2 instances, S3 buckets, and load balancers.
Route 53 also supports domain registration, allowing users to purchase and manage domain names. It provides low-latency DNS resolution, ensuring that users are directed to the nearest data center for improved performance.
Route 53 integrates with other AWS services and allows users to create highly available and fault-tolerant applications by routing traffic based on health checks and geographical location.
