Question 266 of 507
Scaling with Google Cloud operationshardMultiple ChoiceObjective-mapped

Quick Answer

The answer is Cloud CDN, which caches video content at Google’s global edge Points of Presence to serve viewers from the nearest location and reduce latency. This works because Cloud CDN intercepts viewer requests and delivers cached video from the closest edge PoP, eliminating the need for every request to travel all the way to the origin servers in us-central1. By offloading the origin and shortening the network path for viewers in Asia and Europe, Cloud CDN directly addresses high latency without requiring server replication or bandwidth upgrades. On the Google Cloud Digital Leader exam, this scenario tests your understanding of how edge caching solves global content delivery challenges, often appearing as a trap where candidates might mistakenly choose a regional load balancer or additional compute instances. Remember the key distinction: load balancers distribute traffic across servers, but only a CDN caches content at the edge to minimize round trips. Memory tip: think “CDN = Cache at the Doorstep, Not the Warehouse.”

Cloud Digital Leader Scaling with Google Cloud operations Practice Question

This GCDL practice question tests your understanding of scaling with google cloud operations. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.

A digital media company hosts video content globally. They want to reduce origin server load and deliver content faster to viewers worldwide. Their current architecture routes all viewer requests directly to the origin servers in `us-central1`, causing high latency for viewers in Asia and Europe. Which Google Cloud networking capability addresses this?

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

Enable Cloud CDN to cache video content at Google's global edge PoPs, serving viewers from the nearest location.

Cloud CDN uses Google's global edge Points of Presence (PoPs) to cache video content closer to viewers, reducing latency and offloading origin servers. When a viewer requests content, Cloud CDN serves it from the nearest edge cache if available, avoiding a direct trip to the origin in us-central1. This directly addresses the high latency for viewers in Asia and Europe without requiring server replication or bandwidth increases.

Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

  • Deploy identical origin servers in every Google Cloud region globally.

    Why it's wrong here

    Replicating full origin servers in every region is operationally expensive and complex to synchronize. CDN achieves the same performance benefit by caching at edge PoPs without full origin replication.

  • Enable Cloud CDN to cache video content at Google's global edge PoPs, serving viewers from the nearest location.

    Why this is correct

    Cloud CDN caches video content at edge PoPs globally. Asian viewers receive content from nearby PoPs (not us-central1), reducing latency significantly and offloading origin servers.

    Related concept

    Read the scenario before looking for a memorised answer.

  • Use Cloud VPN to route viewer traffic through a direct tunnel to the origin servers.

    Why it's wrong here

    VPN creates encrypted tunnels between networks — it doesn't cache content or improve CDN-style performance. VPN adds overhead rather than reducing latency.

  • Increase the origin servers' network bandwidth to handle more simultaneous viewer connections.

    Why it's wrong here

    More bandwidth on the origin doesn't reduce geographic latency for distant viewers. CDN fundamentally solves the distance problem by moving content closer to users.

Common exam traps

Common exam trap: answer the scenario, not the keyword

Cisco often tests the misconception that 'more bandwidth' or 'replicating servers' is the primary solution for global latency, when in fact edge caching (Cloud CDN) is the correct, cost-effective approach for static and dynamic content delivery.

Detailed technical explanation

How to think about this question

Cloud CDN leverages Google's global edge network with over 200 PoPs, using HTTP/2 and QUIC for efficient content delivery. It supports cache modes like CACHE_ALL_STATIC and FORCE_CACHE_ALL, and respects cache-control headers for TTL management. In a real-world scenario, a video platform streaming to users in Tokyo and London would see latency drop from 200ms+ to under 20ms by serving cached segments from edge nodes in Tokyo and London, while the origin in us-central1 only handles cache misses.

KKey Concepts to Remember

  • Read the scenario before looking for a memorised answer.
  • Find the constraint that changes the correct option.
  • Eliminate answers that are true in general but not in this case.

TExam Day Tips

  • Watch for words such as best, first, most likely and least administrative effort.
  • Review why wrong options are wrong, not only why the correct option is correct.

Key takeaway

Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Real-world example

How this comes up in practice

A healthcare organisation deploys an application with a public-facing web tier and a private database tier. The database subnet has no public IP and only accepts connections from the web tier's security group. Questions like this test whether you can design cloud network isolation using VNets/VPCs, subnets, and security group rules.
