Answer: Use an Aurora global database for physical cross-Region replication.Use Amazon S3 with cross-Region replication for static content and resources.Deploy the web and application tiers in Regions across the world., Introduce Amazon Route 53 with latency-base routing and Amazon CloudFront distributions.Ensure the web and application tiers are each in Auto Scaling groups.
The correct answers are D and E. Here's the explanation: 1. **D. Use an Aurora global database for physical cross-Region replication. Use Amazon S3 with cross-Region replication for static content and resources. Deploy the web and application tiers in Regions across the world.** - **Aurora Global Database:** This option addresses the requirement for optimal performance by ensuring fast local reads and low latency through cross-Region replication of the Aurora MySQL database. Aurora Global Databases can provide fast recovery and low-latency global reads since the data is physically replicated across multiple AWS regions. - **Amazon S3 with Cross-Region Replication:** By storing static content in Amazon S3 and enabling cross-Region replication, content can be served from the nearest region to users, reducing latency and improving load times for a global audience. - **Deploying Web and Application Tiers Globally:** This improves performance by ensuring that users are served from the closest server, reducing latency and response times. Deploying in multiple regions also helps in handling the expected spike in traffic. 2. **E: Introduce Amazon Route 53 with latency-based routing and Amazon CloudFront distributions. Ensure the web and application tiers are each in Auto Scaling groups.** - **Amazon Route 53 Latency-Based Routing:** This ensures that users are directed to the region that provides the lowest latency, thereby optimizing performance worldwide. - **Amazon CloudFront:** Using CloudFront can cache static and dynamic content at edge locations globally, reducing load on the origin servers and speeding up responses for viewers by delivering content more quickly. - **Auto Scaling Groups for Web and Application Tiers:** This ensures that the infrastructure can automatically scale in response to traffic spikes, maintaining performance and availability during the anticipated surge. These steps help in achieving low latency, high performance, and availability for the global audience during the launch period.

An online magazine will launch its latest edition this month .This edition will be the first to be distributed globally .The magazine's dynamic website currently uses an Application Load Balancer in front of the web tier, a fleet of Amazon EC2 instances for web and application servers and Amazon Aurora MySQL. Portions of the website include static content and almost all traffic is read-only The magazine is expecting a significant spike in internet traffic when the new edition is launched Optimal performance is a top priority for the week following the launch. Which combination of steps should a solutions architect take to reduce system response times for a global audience? (Select TWO.)
A
Use logical cross-Region replication to replicate the Aurora MySQL database to a secondary Region. Replace the web servers with Amazon S3. Deploy S3 buckets in cross Region replication mode.
B
Ensure the web and application tiers are each in Auto Scaling groups. Introduce an AWS Direct Connect connection.Deploy the web and application tiers in Regions across the world.
C
Migrate the database from Amazon Aurora to Amazon RDS for MySQL. Ensure all three of the application tiersweb,application, and database are in private subnets.
D
Use an Aurora global database for physical cross-Region replication.Use Amazon S3 with cross-Region replication for static content and resources.Deploy the web and application tiers in Regions across the world.
E
Introduce Amazon Route 53 with latency-base routing and Amazon CloudFront distributions.Ensure the web and application tiers are each in Auto Scaling groups.
