1Z0-1072-25 Question 159
Single answerYour organization hosts an e-commerce platform across two Oracle Cloud Infrastructure (OCI) regions for high availability and fault tolerance. Recently, users have reported slow response times when accessing the application from certain parts of the world. You suspect that inter-region network latency may be affecting overall performance. Which action would best help you accurately measure and analyze inter-region latency so you can optimize your multi-region design?
- A
Collect custom metrics using OCI Monitoring from a single region and infer the latency from application logs
- B
Set up OCI Health Checks with latency probes from multiple strategic vantage points to each region
- C
Use operating system commands (ping, traceroute) from your on-premises environment only to measure network paths
- D
Deploy a multi-region Autonomous Database, which automatically handles latency between regions
Show answer and explanation
Correct answer: B
Explanation
Using multiple global vantage points in OCI Health Checks or other distributed monitoring tools is critical to accurately gauge inter-region latency. By gathering round-trip metrics across different geographic locations, you can identify which segment of the network path contributes most to latency and take steps to optimize (e.g., choosing a closer region, using FastConnect, or leveraging Traffic Management with OCI DNS). Refer to the Oracle Cloud Infrastructure documentation under 'Health Checks and Diagnostics' to learn how to configure and interpret latency tests for multi-region deployments.
- A. Incorrect.
Option 1: Incorrect. Collecting custom metrics from only one region and using application logs can miss critical network paths and regions of interest. Without distributed vantage points, you only get partial insights and may not accurately measure inter-region latency.
- B. Correct.
Option 2: Correct. OCI Health Checks allow you to configure latency probes from multiple vantage points around the world. By testing endpoints in each region, you gain a clear understanding of round-trip times and can pinpoint potential latency bottlenecks or regional network issues.
- C. Incorrect.
Option 3: Incorrect. While ping and traceroute from on-premises can provide some data, relying solely on these local tests may not capture the entire path between the two OCI regions. You need vantage points that are located closer to or within the respective regions for accurate measurement.
- D. Incorrect.
Option 4: Incorrect. Deploying a multi-region Autonomous Database does not automatically resolve network latency issues between regions. It can simplify some aspects of data replication, but the underlying physical or network distance still affects latency, which must be measured and reduced through networking best practices.
