PCDOE Optimizing service performance Practice Question
This PCDOE practice question tests your understanding of optimizing service performance. 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 DevOps team wants to serve static content from a Cloud Storage bucket with low latency globally. They also need TLS termination. Which load balancer type should they use?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
External HTTP(S) Load Balancer
External HTTP(S) Load Balancer is the correct choice because it provides global anycast IP addresses, TLS termination at the Google Front End (GFE), and integrates directly with Cloud Storage buckets as a backend. This enables low-latency content delivery worldwide while offloading SSL decryption to the load balancer.
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.
✗
External Network Load Balancer
Why it's wrong here
Network LB does not support backend buckets or TLS termination.
✗
SSL Proxy Load Balancer
Why it's wrong here
SSL proxy is for TCP traffic with SSL offload, not for HTTP static content.
✗
Internal HTTP(S) Load Balancer
Why it's wrong here
Internal load balancer is for VPC internal traffic, not global access.
✓
External HTTP(S) Load Balancer
Why this is correct
External HTTP(S) LB supports backend buckets, global anycast IP, and TLS termination.

Common exam traps
Common exam trap: answer the scenario, not the keyword
Google Cloud often tests the misconception that any load balancer with 'SSL' or 'Proxy' in its name can serve web content to Cloud Storage, but only the External HTTP(S) Load Balancer provides the necessary HTTP protocol support and global anycast routing for static content delivery.
Detailed technical explanation
How to think about this question
The External HTTP(S) Load Balancer uses Google's global anycast IP addresses to route traffic to the nearest GFE, which terminates TLS and forwards requests to Cloud Storage via HTTPS. Under the hood, it leverages Google's front-end infrastructure and supports features like Cloud CDN integration, custom headers, and URL-based routing, making it ideal for serving static assets globally.
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 media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.
