    Hi Justin,
    Thanks for the feedback.
    Since the questions are shuffled, your Set 4, Question 9 is different from mine.
    Is this the question you are referring to?

    A legal consulting firm is running a WordPress website on EC2 instances deployed across multiple Availability Zones with a Multi-AZ RDS MySQL database instance. Their website is designed to use an eventual consistency model and performs a high number of read and write operations. There is a growing number of people who are reporting that the website is slow and after checking, the root cause is due to the slow read processing in your database tier.

    Which of the following options would solve this issue? (Select THREE.)

    > I understand that the question indicates high number of read and writes to to the database. However, the main issues identified on the question is the slow read processing in the database tier.
    Therefore, three options are related to increasing read performance.
    – Adding RDS read replicas
    – Adding an Elasticache tier for caching
    – Adding CloudFront for caching of static contents and choosing proper EC2 sizing.
    If there are any static assets in the database, it could be beneficial to de-couple them and have their own caching on CloudFront. As for the EC3 sizes, some small EC2 instance sizes have slower network throughput compared to larger instances. We need to make sure that there is no bottleneck on the EC2 instances to enhance the performance of the web application.

    Hope this helps.
