A company observes an increase in Amazon EC2 costs in its most recent bill The billing team notices unwanted vertical scaling of instance types for a couple of EC2 instances A solutions architect needs to create a graph comparing the last 2 months of EC2 costs and perform an in-depth analysis to identify the root cause of the vertical scaling

How should the solutions architect generate the information with the LEAST operational overhead?

A. Use AWS Budgets to create a budget report and compare EC2 costs based on instance types

B. Use Cost Explorer's granular filtering feature to perform an in-depth analysis of EC2 costs based on instance types

C. Use graphs from the AWS Billing and Cost Management dashboard to compare EC2 costs based on instance types for the last 2 months

D. Use AWS Cost and Usage Reports to create a report and send it to an Amazon S3 bucket Use Amazon QuickSight with Amazon S3 as a source to generate an interactive graph based on instance types.

Cuando ponga in depth es decir un analysis profundo es mejor usar cost explorer granular analisis. La opción C es demasiado generalista.

A solutions architect is designing a two-tiered architecture that includes a public subnet and a database subnet. The web servers in the public subnet must be open to the internet on port 443. The Amazon RDS for MySQL D6 instance in the database subnet must be accessible only to the web servers on port 3306.

Which combination of steps should the solutions architect take to meet these requirements? (Select TWO.)

A. Create a network ACL for the public subnet Add a rule to deny outbound traffic to 0 0 0 0/0 on port 3306

B. Create a security group for the DB instance Add a rule to allow traffic from the public subnet CIDR block on port 3306

C. Create a security group for the web servers in the public subnet Add a rule to allow traffic from 0 0 0 O'O on port 443

D. Create a security group for the DB instance Add a rule to allow traffic from the web servers' security group on port 3306

E. Create a security group for the DB instance Add a rule to deny all traffic except traffic from the web servers' security group on port 3306

A company has an application that generates a large number of files, each approximately 5 MB in size. The files are stored in Amazon S3. Company policy requires the files to be stored for 4 years before they can be deleted Immediate accessibility is always required as the files contain critical business data that is not easy to reproduce. The files are frequently accessed in the first 30 days of the object creation but are rarely accessed after the first 30 days

Which storage solution is MOST cost-effective?

A. Create an S3 bucket lifecycle policy to move Mm from S3 Standard to S3 Glacier 30 days from object creation Delete the Tiles 4 years after object creation
