Google ACE Deploying and implementing a cloud solution Practice Question
This ACE practice question tests your understanding of deploying and implementing a cloud solution. 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.
Which TWO statements are correct about deploying an application with an HTTP(S) load balancer on Compute Engine?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
A network load balancer can be used for UDP traffic.
Option A is correct because a network load balancer (external) operates at Layer 4 and can forward UDP traffic, unlike HTTP(S) load balancers which only handle HTTP/HTTPS at Layer 7. This makes it suitable for UDP-based applications such as DNS, gaming, or streaming.
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.
✓
A network load balancer can be used for UDP traffic.
Internal load balancers are passthrough, no proxy needed.
✓
An HTTP(S) load balancer requires a backend service with a health check.
Why this is correct
Health checks are mandatory for HTTP(S) load balancers.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates confuse the TCP proxy load balancer's ability to handle HTTP traffic with the HTTP(S) load balancer's Layer 7 capabilities, leading them to incorrectly think TCP proxy is restricted to non-HTTP traffic.
Detailed technical explanation
How to think about this question
Under the hood, Google Cloud HTTP(S) load balancers are global, software-defined, and use a proxy-based architecture at the edge (Google Front End servers) to terminate HTTP/HTTPS connections, then forward traffic over internal Google Cloud networks to backend instances. Health checks are mandatory for the backend service to ensure traffic is only sent to healthy instances; without a health check, the load balancer cannot determine instance status and will fail to route traffic correctly. This is enforced at the API level — creating a backend service without a health check returns an error.

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
An e-commerce site experiences heavy traffic on Black Friday and near-zero traffic during off-peak weeks. Rather than provisioning permanent large VMs, the team uses auto-scaling groups that add capacity automatically under load and reduce it overnight. Questions like this test whether you understand elasticity, availability zones, and cloud compute scaling patterns.
