The correct answer is that an internal TCP/UDP load balancer can be used for traffic within a VPC, and a global external HTTP(S) load balancer can distribute traffic across multiple regions. This is because Google Cloud’s load balancing types are designed for specific traffic patterns: global external load balancers operate at the edge of Google’s network to route user requests to the closest healthy backend across regions, while internal load balancers are regional and handle private traffic between instances inside a Virtual Private Cloud without exposing a public IP. On the Google Professional Cloud Developer exam, this question tests your ability to distinguish between the four main load balancer categories—global external, regional external, regional internal, and proxy-based—and their supported protocols. A common trap is confusing SSL proxy load balancers (which only handle TCP with SSL termination) with network load balancers (which support both TCP and UDP). Remember the mnemonic: “Global HTTP(S) goes worldwide; Internal TCP/UDP stays inside.”
PCD Integrating Google Cloud services Practice Question
This PCD practice question tests your understanding of integrating google cloud services. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. 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? (Choose two.)
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Global external HTTP(S) load balancer can distribute traffic across multiple regions.
Options A and B are correct. A is correct because global external HTTP(S) load balancers can distribute traffic across multiple regions. B is correct because internal TCP/UDP load balancers operate within a VPC. C is wrong because SSL proxy load balancers only support TCP with SSL. D is wrong because network load balancers support both TCP and UDP. E is wrong because not all load balancers support IPv6.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

For each option: why learners choose it and why it is or isn't the right answer here.
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
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.
Use explanations to understand the rule behind the answer.
TExam Day Tips
→Underline the problem statement mentally.
→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.
