1Z0-1072-25 Question 158
Select 2Your organization hosts a globally distributed application running in two OCI regions: Ashburn (primary) and Frankfurt (secondary). Recently, end users have reported increased response times when requests traverse from Ashburn to Frankfurt. You suspect the issue might be related to network path variations or congestion. Which TWO actions can you take to accurately analyze inter-region latency and diagnose potential root causes?
- A
Deploy a small compute instance in each region and run trace-like diagnostic tools (e.g., traceroute) to measure and compare latency over multiple paths.
- B
Use the OCI Network Path Analyzer to visualize the network path between Ashburn and Frankfurt, identifying any potential bottlenecks or routing anomalies.
- C
Increase the shape of the compute instances from Standard to High I/O in the Ashburn region to reduce overall network latency.
- D
Set up an on-premises VPN connection that reroutes all traffic through a local data center before sending it to the Frankfurt region for more detailed monitoring.
Show answer and explanation
Correct answers: A, B
Explanation
To effectively analyze inter-region latency, you need to isolate potential network path anomalies and gather data on routing hops, packet loss, and latency spikes. Using OCI Network Path Analyzer provides a graphical overview of the path and potential bottlenecks, while deploying instances in each region and running diagnostic tools offers real-time visibility of latency metrics. Refer to OCI documentation on Network Path Analyzer and networking best practices (docs.oracle.com/en/oci/) for more detailed guidelines.
- A. Correct.
Correct. Deploying test workloads in each region and running well-known network diagnostic tools provides direct insight into latency, packet loss, and the path taken by traffic. This method helps you pinpoint if the latency is caused by regional routing, peering points, or other network factors.
- B. Correct.
Correct. OCI Network Path Analyzer (within the Observability & Management set of tools) helps visualize and troubleshoot traffic flows between two endpoints. It can identify routing misconfigurations, asymmetric paths, or potential network congestion along the route.
- C. Incorrect.
Incorrect. Merely increasing the compute shape often addresses compute resource constraints (CPU, memory), not network path issues. It won't fix routing or congestion between regions.
- D. Incorrect.
Incorrect. While on-premises VPN can route traffic differently, it would complicate the topology and often increase latency unless there's a known optimized route. This is not a recommended or straightforward way to analyze inter-region latency within OCI.
