1Z0-1072-25 Question 157
Single answerYour organization has deployed an e-commerce platform across two OCI regions�Ashburn and Tokyo. Recently, end users have reported slower checkout times during peak hours. You suspect high inter-region network latency is contributing to the delay. Which approach is recommended to accurately measure and analyze real-time latencies between these two regions?
- A
Configure database replication logs in each region and compare data transfer times
- B
Use OCI Network Path Analyzer or Health Checks under Observability and Management to directly measure round-trip times
- C
Enable VCN flow logs in both regions and rely on the log timestamps for latency insights
- D
Rely exclusively on aggregated network usage metrics in the console to infer latency peaks
Show answer and explanation
Correct answer: B
Explanation
To accurately analyze inter-region latency, leverage OCI� Observability and Management tools such as Network Path Analyzer and Health Checks. These services provide detailed round-trip time measurements and help you visualize traffic flows between regions. They are more accurate than relying on replication logs, flow logs, or aggregated metrics, which either focus on different aspects of network and database performance or lack sufficient granularity for effective real-time latency troubleshooting. Refer to the official Oracle Cloud Infrastructure documentation for Observability & Management to learn how to set up and interpret metrics from these tools.
- A. Incorrect.
Incorrect. While replication logs can show how long it takes for database changes to propagate, they are not designed to provide granular real-time latency metrics for network analysis. They primarily capture replication timelines rather than detailed inter-region latency patterns.
- B. Correct.
Correct. OCI� Network Path Analyzer and Health Checks are specifically designed to measure network latency between regions. They provide deeper visibility into the path and round-trip times, allowing you to pinpoint bottlenecks and make data-driven decisions about optimizing traffic flow.
- C. Incorrect.
Incorrect. VCN flow logs provide information about IP traffic flow within a VCN, useful for troubleshooting security rules or connection issues. However, they are not intended for precise inter-region latency measurement because they don�t capture real-time round-trip network data.
- D. Incorrect.
Incorrect. Aggregated network usage metrics can show overall bandwidth utilization or packet rates. These high-level metrics alone do not accurately depict the hop-by-hop latency or the real-time latencies you need to diagnose peak hour slowdowns.
