COURSE 3 – MIGRATING TO THE CLOUD QUIZ ANSWERS

1. What is an example of rehosting an application?

Before moving an application to the cloud, the application is rewritten in a new programing language.
During a migration, older applications are discovered. They are no longer needed and can be turned off.
A containerized application can be moved from on premises to the cloud without making any changes.
All on-premises applications and resources can be easily moved to the cloud except for the load balancers. The existing load balancers are replaced by Elastic Load Balancing (ELB) load balancers.

Explanation: In the process of rehosting an application, the program is moved from one environment to another without any substantial modifications being made to its actual design. To put it another way, it is the same as taking the application and transferring it to a different hosting environment. An example of this would be moving a conventional application that is hosted on-premises to a cloud architecture such as Amazon Web Services or Microsoft Azure. A significant portion of the program has not been altered; nevertheless, it is now operating in a new hosting environment, which allows it to take use of cloud features such as scalability and flexibility.

8. What is a requirement for doing an agentless installation of the AWS Application Discovery Service Agent?

Using VMware vCenter
Using Lambda functions
Using serverless servers on premises
Using Amazon Elastic Compute Cloud (Amazon EC2) instances

Explanation: The most important prerequisite for an agentless installation of the Amazon Web Services Application Discovery Service Agent is that your servers must be using a version of the Windows Management Instrumentation (WMI) service that is capable of supporting the installation. An agent does not need to be installed on each server in order for the AWS Application Discovery Service to gather information about your servers, apps, and dependencies. This is accomplished via the usage of Windows Management Instrumentation (WMI).

9. Which networking service transfers large, ongoing amounts of data between a customer’s data center and the cloud?

AWS Direct Connect
AWS Snowmobile
Virtual private network (VPN)
Internet gateway

10. What is a task that is performed by AWS Application Discovery Service?

Launch replacement applications
Expand the size of Amazon Simple Storage Service buckets
Organize instances into application groups
Remove unwanted resources

Explanation: The service will map the dependencies between apps and servers, as well as identify servers that are present in your on-premises infrastructure. To generate a complete perspective of how various components interact with one another, it gathers information on network connections, communication patterns, and resource use.

For you to carry out this job, the Amazon Web Services Application Discovery Service assists you in gaining insights about your current infrastructure. These insights help plan migrations to the Amazon Web Services cloud. Having a better knowledge of the linkages and dependencies across apps is made possible by the data gathered, which in turn makes the migration process more accessible and more informed.

11. What is a task that is performed by AWS Application Migration Service?

Create test environments for an application
Migrate databases to Amazon Relational Database Service (Amazon RDS)
Create a map of application dependencies
Migrate applications into containers

Explanation: During the migration process, it is essential to do this action in order to guarantee that the server images stored in the AWS cloud will continue to be synced with the servers located on-premises. After the replication has been established, you can use AWS SMS to coordinate and automate the transfer of these server images to AWS EC2 instances. This will streamline the migration process and reduce the amount of time that the resources are unavailable.
