Google PCA Manage and provision cloud infrastructure Practice Question
This PCA practice question tests your understanding of manage and provision cloud infrastructure. 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 true about Cloud Load Balancing?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Regional load balancing supports TCP/UDP traffic.
Regional load balancing supports TCP and UDP traffic because it operates at Layer 4, using the regional forwarding rule to direct packets based on IP protocol, port, and optional session affinity. This allows it to handle non-HTTP workloads such as DNS, VoIP, or gaming traffic that require UDP or raw TCP connections.
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.
✗
All load balancers require a regional forwarding rule.
Why it's wrong here
Global load balancers use global forwarding rules.
✓
Regional load balancing supports TCP/UDP traffic.
Why this is correct
Regional external load balancers (e.g., Network Load Balancer) support TCP and UDP.

✗
Global load balancing supports only HTTP/S traffic.
Internal load balancing is only for traffic within the same VPC.
Why it's wrong here
Internal load balancing is for traffic from the same VPC, but it can also work across peering.
✓
Load balancers can be associated with instance groups in multiple regions.
Why this is correct
Global load balancers can have backends in multiple regions.

Common exam traps
Common exam trap: answer the scenario, not the keyword
Google Cloud often tests the misconception that global load balancers only handle HTTP/S traffic, but in Google Cloud, global load balancers also support TCP and UDP via the global external proxy network load balancer, making option C a common trap.
Detailed technical explanation
How to think about this question
Under the hood, regional load balancers use a regional forwarding rule that maps to a target pool or backend service, enabling direct server return (DSR) for TCP/UDP flows without proxy overhead. In contrast, global load balancers leverage Google's front-end (GFE) infrastructure to terminate connections at the edge and route over Google's backbone, which is why they can support anycast IPs and cross-region failover. A real-world scenario: a gaming company uses a regional TCP/UDP load balancer for low-latency game state synchronization, while a global HTTP/S load balancer serves the web frontend from multiple regions.

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 company's IT admin needs to give a contractor read-only access to production logs without sharing account credentials. Using role-based access control (RBAC) and temporary scoped permissions — not a permanent shared password — is the correct pattern. Questions like this test whether you can apply least-privilege access across cloud identity services.
