Oracle Cloud Infrastructure 2019 Developer Associate — Question 35

You have an external facing web server running in the Oracle Cloud Infrastructure (OCI) London region. You are notified that customers in North America and
Australia are facing high latency while connecting to your web server.
Which services are available on OCI that can help you get current latency statistics to your web server from these markets?

Answer options

• A. Use DNS Zone Management service to check latency over that connection
• B. Setup an IPsec VPN with customers in those markets and check latency over that connection
• C. Use the Internet Intelligence tool. Run tests using the web server's public IP address review traceroute details from different vantage points
• D. Setup a FastConnect with customers in those markets and check latency over that connection

Correct answer: A

Explanation

The correct answer is A because the DNS Zone Management service can provide insights into the latency experienced by customers when connecting to your web server by analyzing DNS resolution times. Options B and D involve setting up private connections, which do not provide real-time latency metrics for external users. Option C, while useful for testing, does not directly utilize OCI's services to get latency statistics from the mentioned markets.
