問題 #115
A company has an application that sells tickets online and experiences bursts of demand every 7 days. The application has a stateless presentation layer running on Amazon EC2. an Oracle database to store unstructured data catalog information, and a backend API layer. The front-end layer uses an Elastic Load Balancer to distribute the load across nine On-Demand Instances over three Availability Zones (AZs). The Oracle database is running on a single EC2 instance. The company is experiencing performance issues when running more than two concurrent campaigns. A solutions architect must design a solution that meets the following requirements:
* Address scalability issues.
* Increase the level of concurrency.
* Eliminate licensing costs.
* Improve reliability.
Which set of steps should the solutions architect take?

A. Create an Auto Scaling group for the front end with a combination of On-Demand and Spot Instances to reduce costs. Convert the tables in the Oracle database into Amazon DynamoDB tables.
B. Create an Auto Scaling group for the front end with a combination of On-Demand and Spot Instances to reduce costs. Create two additional copies of the database instance, then distribute the databases in separate AZs.
C. Convert the On-Demand Instances into Spot Instances to reduce costs for the front end. Convert the tables in the Oracle database into Amazon DynamoDB tables.
D. Create an Auto Scaling group for the front end with a combination of On-Demand and Spot Instances to reduce costs. Convert the Oracle database into a single Amazon RDS reserved DB instance.

答案：A

解題說明：
Explanation
Combination of On-Demand and Spot Instances + DynamoDB.

問題 #116
You have been asked to set up a public website on AWS with the following criteria:
You want the database and the application server running on an Amazon VPC. You want the database to be able to connect to the Internet so that it can be automatically updated to the correct patch level.
You do not want to receive any incoming traffic from the Internet to the database.
Which solutions would be the best to satisfy all the above requirements for your planned public website on AWS? (Choose 2 answers)

A. Set up both the public website and the database on a public subnet and block all incoming requests from the Internet with a Network Access Control List (NACL)
B. Set up both the public website and the database on a private subnet and block all incoming requests from the Internet with a Network Access Control List (NACL). Set up a Security group between the public website and the database which only allows access via port 80.
C. Set up both the public website and the database on a public subnet, and block all incoming requests from the Internet with a security group which only allows access from the IP of the public website.
D. Set up the public website on a public subnet and set up the database in a private subnet which connects to the Internet via a NAT instance.

答案：C,D

解題說明：

Which combination of actions should the solutions architect take to implement the new design while meeting all the requirements? (Select THREE.)

A. Enable Amazon S3 cross-Region replication on the buckets that contain static assets.
B. Enable DynamoDB global tables to achieve a multi-Region table replication.
C. Enable Amazon S3 versioning on the source and destination buckets containing static assets to ensure there is a rollback version available in the event of data corruption.
D. Enable Amazon CloudWatch and create CloudWatch alarms that route traffic to the disaster recovery site when application latency exceeds the desired threshold.
E. Enable Amazon Route 53 health checks to determine if the primary site is down, and route traffic to the disaster recovery site if there is an issue.
