    A company is hosting its production environment on its on-premises servers. Most of the applications are packed as Docker containers that are manually run on self-managed virtual machines. The web servers are using the latest commercial Oracle Java SE suite which costs the company thousands of dollars in licensing costs. The MySQL databases are installed on separate servers configured on a >>>>>>> master-slave <<<<<<< setup for high availability. The company wants to migrate the whole environment to AWS Cloud to take advantage of its flexibility and agility, as well as use OpenJDK to save licensing costs without major changes in its applications.

    Which of the following application migration strategies meet the above requirement?

    I believe using “Master-Slave” is very non-inclusive. Maybe change this to “Primary-Secondary”? 🙂

    Same for question 36, option C….

    Purchase Reserved Amazon EC2 instances for the application instance and database instances to save costs. Create an EC2 Auto Scaling group with Multi-AZ configuration behind a load balancer for the application tier. Implement a >>>>> master-slave <<<<< setup for your database tier. Use Logical Volume Management on the database instances to easily attach new EBS volumes and expand the file system.

    Hi Andre,

    Thanks for the feedback.

    The official MySQL blog has updated the terms they use for “master-slave”.

    We’ll follow their recommendation to use “source-replica” wording for our questions.

    You should see the changes as soon as our team uploads the question update.

    Hope this helps.
