1Z0-1123-25 Question 142
Select 2You are designing a migration plan for a mission-critical Oracle Database running on-premises, which handles high-volume transactions and must meet strict performance SLAs. As the migration architect, you begin by analyzing the current environment and planning how to transition to Oracle Cloud Infrastructure with minimal operational risk. Which two actions should you incorporate as part of your analysis to ensure a successful database migration plan?
- A
A. Collect baseline performance metrics and forecast growth trends to determine the required compute and storage resources in OCI.
- B
B. Migrate large volumes of production data to the cloud environment without testing, to shorten migration timelines.
- C
C. Assess networking and bandwidth requirements, including the potential use of data transfer services to optimize data movement.
- D
D. Ignore compliance requirements for data encryption and assume that the default cloud security settings are sufficient.
- E
E. Identify potential dependency on external systems or applications to plan for synchronized downtime or phased migration.
Show answer and explanation
Correct answers: A, C
Explanation
When analyzing and designing a database migration plan, it is key to study the current database environment to determine performance, resource, and network requirements. Oracle Cloud Infrastructure best practices recommend running performance baselines, forecasting growth, and assessing network needs before migrating. Compliance and security requirements, such as encryption and regulatory adherence, must also be factored in. These steps reduce migration risks, align resources accurately, and help meet strict SLAs in the target cloud environment. Refer to Oracle's documentation on Planning a Database Migration (docs.oracle.com) for detailed guidance on baseline collection, network considerations, and compliance best practices.
- A. Correct.
A. Correct. Gathering current performance metrics (e.g., CPU utilization, I/O throughput, memory usage) and projecting future growth are crucial to sizing your target environment in OCI correctly. This helps avoid over- or under-provisioning and ensures that the migrated database can handle anticipated workloads.
- B. Incorrect.
B. Incorrect. Migrating large volumes of data without proper pre-production testing or proof-of-concept increases the risk of downtime and performance bottlenecks. Proper testing in a staging environment is a best practice.
- C. Correct.
C. Correct. Thoroughly assessing networking requirements, such as bandwidth, latency, and data transfer options, is essential for a successful migration. Sometimes, Oracle Cloud services like Data Transfer Appliance or FastConnect are needed to handle large data sets and maintain performance.
- D. Incorrect.
D. Incorrect. Compliance requirements for encryption (at rest and in transit) cannot be overlooked, especially for critical and sensitive data. Relying solely on default settings may not meet certain regulatory or organizational standards, leading to security and compliance risks.
- E. Incorrect.
E. Incorrect. While understanding external dependencies is important, this option alone does not ensure success in the analysis phase if you do not also plan for resource utilization, performance, or compliance aspects. It is a factor, but on its own, it does not constitute a primary action to ensure a successful migration in this scenario.
