Answer: Create 200 new hosted zones in the Amazon Route 53 console Import zone files.
## Explanation **Correct Answer: A** - Create 200 new hosted zones in the Amazon Route 53 console Import zone files. **Why this is the correct answer:** 1. **Maximize Availability**: Amazon Route 53 is a highly available and scalable DNS service with a 100% availability SLA. It automatically distributes DNS queries across multiple AWS regions and Availability Zones, providing better availability than self-managed DNS servers. 2. **Minimize Operational Overhead**: Route 53 is a fully managed service, eliminating the need for: - Managing EC2 instances - Configuring Auto Scaling groups - Setting up monitoring and alarms - Patching and maintaining operating systems - Managing DNS server software 3. **Scalability**: Route 53 can easily handle 1 million requests per day (which is approximately 11.6 queries per second) and can scale to handle billions of queries per day. 4. **Zone Management**: Route 53 supports importing zone files, making migration straightforward for the 200 zones. **Why the other options are incorrect:** **B. Launch a single large Amazon EC2 instance**: - Single point of failure (not highly available) - Requires ongoing operational overhead (patching, monitoring, scaling) - Doesn't maximize availability **C. Migrate the servers using AWS SMS**: - This simply lifts and shifts the existing DNS servers to EC2 - Doesn't reduce operational overhead - Doesn't maximize availability (still self-managed servers) **D. Launch EC2 instance in Auto Scaling group**: - While better than option B (with Auto Scaling across AZs), it still requires: - Managing EC2 instances - Configuring and maintaining Auto Scaling policies - Managing DNS software - Operational overhead for monitoring and maintenance - Route 53 is a fully managed service that provides better availability with less operational overhead. **Key AWS Services Mentioned:** - **Amazon Route 53**: AWS's scalable DNS web service - **AWS Server Migration Service (AWS SMS)**: Service for migrating on-premises servers to AWS - **Amazon EC2 Auto Scaling**: Service for automatically scaling EC2 instances - **Amazon CloudWatch**: Monitoring and observability service **Best Practice**: When migrating DNS services to AWS, Route 53 is the recommended solution for maximizing availability and minimizing operational overhead, as it's a fully managed service with built-in high availability and scalability.

A company wants to migrate two DNS servers to AWS. The servers host a total of approximately 200 zones and receive 1 million requests each day on average. The company wants to maximize availability while minimizing the operational overhead that is related to the management of the two servers.
What should a solutions architect recommend to meet these requirements?
A
Create 200 new hosted zones in the Amazon Route 53 console Import zone files.
B
Launch a single large Amazon EC2 instance Import zone tiles. Configure Amazon CloudWatch alarms and notifications to alert the company about any downtime.
C
Migrate the servers to AWS by using AWS Server Migration Service (AWS SMS). Configure Amazon CloudWatch alarms and notifications to alert the company about any downtime.
D
Launch an Amazon EC2 instance in an Auto Scaling group across two Availability Zones. Import zone files. Set the desired capacity to 1 and the maximum capacity to 3 for the Auto Scaling group. Configure scaling alarms to scale based on CPU utilization.
