A company needs to implement a managed file system to host Windows file shares for users on premises. Resources in the AWS Cloud also need access to the data on these file shares. A SysOps administrator needs to present the user file shares on premises and make the user file shares available on AWS with minimum latency.
What should the SysOps administrator do to meet these requirements?

1. A. Set up an Amazon S3 File Gateway.
2. B. Set up an AWS Direct Connect connection.
3. C. Use AWS DataSync to automate data transfers between the existing file servers and AWS.
4. D. Set up an Amazon FSx File Gateway.

Correct Answer: D
Amazon FSx provides a fully managed file system that is optimized for Windows-based workloads and can be used to create file shares that can be accessed both on premises and in the AWS Cloud. The file shares that are created in Amazon FSx are highly available and can be accessed with low latency. Additionally, Amazon FSx supports Windows-based authentication, making it easy to integrate with existing Windows user accounts.

A company has an application that customers use to search for records on a website. The application's data is stored in an Amazon Aurora DB cluster. The application's usage varies by season and by day of the week.
The website's popularity is increasing, and the website is experiencing slower performance because of increased load on the DB cluster during periods of peak activity. The application logs show that the performance issues occur when users are searching for information. The same search is rarely performed multiple times.
A SysOps administrator must improve the performance of the platform by using a solution that maximizes resource efficiency.
Which solution will meet these requirements?

1. A. Deploy an Amazon ElastiCache for Redis cluster in front of the DB cluste
2. B. Modify the application to check the cache before the application issues new queries to the databas
3. C. Add the results of any queries to the cache.
4. D. Deploy an Aurora Replica for the DB cluste
5. E. Modify the application to use the reader endpoint for search operation
6. F. Use Aurora Auto Scaling to scale the number of replicas based on loa
7. G. Most Voted
8. H. Use Provisioned IOPS on the storage volumes that support the DB cluster to improve performance sufficiently to support the peak load on the application.
9. I. Increase the instance size in the DB cluster to a size that is sufficient to support the peak load on the applicatio
10. J. Use Aurora Auto Scaling to scale the instance size based on load.
