Question 1

A company has multiple applications running on-premises and plans to migrate them to AWS using Server Migration Service (SMS). They want to replicate multiple applications with minimal downtime. What is the best replication interval for minimizing application downtime?

Correct Answer: 1 hour

For minimal application downtime, AWS SMS allows configuring replication intervals as low as 1 hour. This helps in syncing on-premises applications with the AWS environment more frequently, reducing downtime.

Question 2

A global company is planning to use AWS Server Migration Service (SMS) to migrate its workloads running on multiple VMware environments. They want to ensure that the entire migration process is secure. How is data transferred to AWS during the migration?

Correct Answer: Over SSL and encrypted on S3

During the migration, AWS SMS transfers data over SSL for a secured data transfer, and data is also encrypted on Amazon S3 to add an extra layer of security.

Question 3

A company is using the Server Migration Service (SMS) to migrate its on-premises server infrastructure to AWS. They want to automate the process of validating migrated AMIs using AWS Lambda. How can they trigger Lambda upon completing an AMI replication in SMS?

Correct Answer: Configure AWS SMS to send replication notifications to an SNS topic, then trigger Lambda from the SNS topic

By configuring AWS SMS to send replication notifications to an SNS topic and then triggering the Lambda function from that SNS topic, you can automate the process of validating migrated AMIs with minimal manual intervention.
