Cloud Digital Leader Why Cloud Technology Can Transform Business Practice Question
A global e-commerce company is moving its user-facing application to Google Cloud to improve performance for customers worldwide. They need low-latency content delivery and fast DNS resolution. Which TWO Google Cloud services should they use? (Choose 2)
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Cloud CDN
Cloud CDN uses Google's global edge cache to deliver content with low latency. Cloud DNS provides fast, reliable DNS resolution. Cloud Load Balancing distributes traffic but does not cache content; Cloud Armor is for security; Cloud Interconnect is for hybrid connectivity.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Cloud CDN
Why this is correct
Cloud CDN caches static and dynamic content at Google's global edge points of presence, so users retrieve data from a location geographically close to them. This reduces round-trip time, decreases latency, and unloads the origin server, directly improving the performance of a global e-commerce application's page loads and media delivery.
- ✓
Cloud DNS
Why this is correct
Cloud DNS uses anycast routing with servers distributed worldwide to provide low-latency, authoritative DNS resolution. By quickly resolving a domain to the nearest healthy backend IP, it shortens the time to establish the initial connection, which is critical for global users experiencing a fast and responsive e-commerce site.
- ✗
Cloud Interconnect
Why it's wrong here
Cloud Interconnect establishes dedicated physical connections between an on-premises network and Google Cloud, ensuring reliable throughput and lower packet loss for hybrid workloads. However, it does not place content closer to global end users or accelerate public internet traversal, so it has minimal impact on reducing user-facing latency for a geographically distributed e-commerce audience.
- ✗
Cloud Armor
Why it's wrong here
Cloud Armor is a security service that provides DDoS protection and web application firewall rules to filter malicious traffic. While it can inspect requests and enforce policies at Google's edge, it does not cache content, shorten network paths, or resolve DNS faster, so it is not a performance optimization service for global application speed.
- ✗
Cloud Load Balancing
Why it's wrong here
Cloud Load Balancing distributes incoming traffic across multiple backend instances or regions, improving availability and preventing overload on any single resource. However, it does not cache content at edge locations nor accelerate DNS resolution; it only routes existing requests, so by itself it cannot reduce the latency that global users experience when fetching static assets or connecting to the application.
