An enterprise is migrating a 50 TB Oracle database to Amazon Aurora PostgreSQL. The migration must have near-zero downtime. The source database uses complex stored procedures and proprietary Oracle features. How should the Solutions Architect execute this migration?

A company is migrating a critical application to AWS. The application consists of 50 VMs running on VMware. The business requires that the migration be completed with near-zero downtime. The IP addresses of the servers must change during the migration. Which AWS service is BEST suited for this migration?

A company is migrating a large-scale data warehouse to Amazon Redshift. The on-premises data warehouse is 100 TB. They have a 10 Gbps AWS Direct Connect connection. They want to migrate the historical data and then set up continuous replication for ongoing changes until the final cutover. Which combination of services should they use? (Select TWO)

The on-premises internet connection is 1 Gbps, but only 200 Mbps can be allocated for the migration. The migration must be completed within 3 weeks. Which data transfer strategy is feasible and MOST cost-effective?

An enterprise is migrating 500 VMware virtual machines from their on-premises data center to AWS. They want to minimize downtime during the cutover. The VMs run a mix of Windows and Linux. The company wants a tool that continuously replicates the VMs to AWS and allows for non-disruptive testing before the final cutover. Which service is BEST suited for this migration?

An enterprise is migrating its analytics platform to AWS. They have 10 PB of historical data currently stored on an on-premises NAS. The data must be migrated to Amazon S3. Once in S3, the data will be queried by Amazon Athena. The data contains sensitive PII that must be encrypted at rest using keys managed by the enterprise. The migration must be completed within 2 months. Which combination of actions should the Architect take? (Select THREE)

A company is migrating a large monolithic application to AWS. The application uses a hardcoded IP address to connect to an on-premises legacy mainframe. The mainframe cannot be updated to use a new IP address. The company plans to migrate the mainframe to AWS in the future, but for now, the application running in AWS must be able to reach the mainframe using the exact same hardcoded IP address. How can the Architect achieve this?

An enterprise is migrating a large Oracle database to Amazon Aurora PostgreSQL. The database contains complex PL/SQL stored procedures. The migration must be completed with minimal downtime. Which combination of AWS tools should the Architect use to perform this migration?

A company is migrating 500 VMware virtual machines to AWS. They want to use a lift-and-shift approach with minimal downtime. They need to continuously replicate the VMs to AWS and perform cutovers during small maintenance windows. Which FOUR steps should the architect include in the migration plan? (Select FOUR)

An enterprise is migrating a massive on-premises data archive (2 Petabytes) to Amazon S3. Their internet connection is 1 Gbps, which is heavily utilized by production traffic. They need to migrate the data securely within 30 days. Which FOUR actions should the architect take? (Select FOUR)

A company wants to migrate a 50 TB on-premises NFS file share to Amazon EFS. The migration must be done securely over the internet, as there is no Direct Connect or VPN. The data changes frequently, so a final sync is required just before cutover. Which AWS service is BEST suited for this migration?

A company is migrating a large PostgreSQL database to Amazon Aurora PostgreSQL. The database is currently 15 TB. The company wants to minimize downtime during the cutover.
