Select 3A technology company plans to migrate its on-premises data center to Oracle Cloud Infrastructure. The environment includes a mix of Windows and Linux VMs hosting mission-critical applications, as well as Oracle Database instances and associated services. To ensure a seamless transition, the migration team wants to discover all relevant resources and their interdependencies. Which THREE actions below are recommended practices to accurately identify resource utilization and dependencies during the on-premises discovery phase?
- A
Deploy an agent-based or agentless discovery tool to collect performance and utilization data from each server.
- B
Estimate average CPU and memory usage by reviewing the monthly electricity bills for the data center.
- C
Use network and endpoint scanning to identify systems that are communicating with the target workloads.
- D
Rely exclusively on outdated technical documentation last updated three years ago.
- E
Interview application owners and technical teams to map out dependencies, communication flows, and performance peaks.
Show answer and explanation
Correct answers: A, C, E
Explanation
When performing source discovery, Oracle Cloud Infrastructure best practices emphasize using comprehensive methods�such as automated discovery tools, network scanning, and interviews with stakeholders�to gather accurate data on resource usage and application dependencies. This multi-pronged approach is recommended in Oracle� migration guidelines, ensuring no hidden or outdated information impacts the migration plan.
- A. Correct.
Correct: Automated discovery tools provide detailed metrics on CPU, memory, disk, and network usage. Oracle best practices recommend thorough data collection using methods such as agent-based discovery for consistent and accurate assessment.
- B. Incorrect.
Incorrect: While power consumption can reflect overall activity, it provides no meaningful detail on individual server resource usage or application dependencies. This approach can lead to imprecise estimation.
- C. Correct.
Correct: Network scans help uncover devices and services communicating with the target environment, ensuring that hidden dependencies or external connections are accounted for before migration.
- D. Incorrect.
Incorrect: Relying solely on outdated documentation introduces significant risk because system configurations, application topologies, and hardware allocations may have changed over time.
- E. Correct.
Correct: Engaging application teams is crucial to identify complex dependencies, service communication patterns, and critical performance windows that might not be evident from automated reports alone.
