Oracle Cloud Infrastructure 2025 Migration Architect Professional. Professional level, Oracle. Free question with the correct answer and a full explanation.

1Z0-1123-25 Question 38

Select 2

You are tasked with migrating a multi-tier application from on-premises servers to Oracle Cloud Infrastructure (OCI). You decide to use the Oracle Cloud Migrations service to discover existing on-premises resources and plan the migration. Which two actions must you take to ensure successful discovery and inclusion of your on-premises environment in a migration plan?

  1. A

    Deploy the Oracle Cloud Migrations agent or configure agentless connectivity for your on-premises servers so the service can collect data.

  2. B

    Provide valid credentials and register your on-premises infrastructure as a source in the Oracle Cloud Migrations console.

  3. C

    Reassign all on-premises network interfaces to ephemeral public IP addresses prior to discovery.

  4. D

    Disable any local or host-based firewalls in your data center until you complete the migration.

  5. E

    Migrate your local DNS records to Oracle Cloud DNS before running any discovery jobs.

Show answer and explanation

Correct answers: A, B

Explanation

To use Oracle Cloud Migrations, you must ensure that your on-premises environment is accessible through agent-based or agentless discovery and that the service has valid credentials to connect and gather information. While network access and credential setup are crucial, reassigning IP addresses, disabling all firewalls, or migrating DNS records ahead of time are not required steps for basic discovery. For more details on configuring source environments and the discovery process, see the Oracle Cloud Migrations documentation and best practices guides on the Oracle Help Center.

  • A. Correct.

    Option 1 is correct. You must either install the Oracle Cloud Migrations agent or configure an agentless connection from your on-premises servers to OCI. This allows the service to collect configuration data and inventory details during discovery.

  • B. Correct.

    Option 2 is correct. You must provide valid credentials to the Oracle Cloud Migrations service and define your on-premises environment as a source. This process authorizes OCI to connect to your environment and gather information about target workloads for migration planning.

  • C. Incorrect.

    Option 3 is incorrect. There is no requirement to switch to ephemeral public IP addresses before discovery. The Oracle Cloud Migrations service can discover on-premises servers through existing internal IP addresses and configured connectivity, such as a VPN or FastConnect, as long as it has proper network access.

  • D. Incorrect.

    Option 4 is incorrect. Completely disabling firewalls is not recommended; instead, you should configure rules to allow inbound/outbound traffic for discovery. Disabling all firewalls could introduce security risks.

  • E. Incorrect.

    Option 5 is incorrect. Migrating DNS records to Oracle Cloud DNS is not an essential prerequisite for discovery. The Oracle Cloud Migrations service can discover resources through the existing DNS setup as long as network connectivity and credentials are properly configured.
