Question 195 of 509

Manage implementation of cloud architecture →mediumMultiple SelectObjective-mapped

Quick Answer

The answer is that Google Cloud HTTPS Load Balancers are global resources and use a single anycast IP address. This is because the load balancer operates at the application layer, fronted by Google’s global anycast infrastructure, which allows a single IP address to serve traffic from the closest Google edge location to the user, regardless of where the backend instances are deployed across regions. On the Google Professional Cloud Architect exam, this concept tests your understanding of global versus regional load balancing, a common differentiator from internal or network load balancers. A frequent trap is assuming HTTPS load balancers are regional like TCP/UDP load balancers, but remember they are designed for global, anycast-based distribution. To lock this in, use the memory tip: “Global IP, anycast trip” — the HTTPS Load Balancer uses one IP that anycast routes to the nearest healthy backend, making it a truly global resource.

Google PCA Manage implementation of cloud architecture Practice Question

This PCA practice question tests your understanding of manage implementation of cloud architecture. 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 Google Cloud HTTPS Load Balancers?

Question 1mediummulti select

Full question →

A
They support only external backends, such as internet-facing instances.
Why wrong: They support internal backends as well (e.g., Compute Engine instances with internal IPs).
B
They support only IPv4 traffic.
Why wrong: They support both IPv4 and IPv6.
C
They can forward traffic to backends in multiple regions, including instances in different VPC networks.
Global HTTPS Load Balancers support multi-region backends, including across VPCs via Network Endpoint Groups.
D
They can be used to load balance internal HTTP(S) traffic within a VPC.
Why wrong: Internal HTTP(S) load balancing requires Internal Load Balancer, not HTTPS Load Balancer.
E
They are global resources and use a single anycast IP address.
HTTPS Load Balancers are global, with a single IP that routes to the nearest healthy backend.

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

✓

They can forward traffic to backends in multiple regions, including instances in different VPC networks.

Option C is correct because Google Cloud HTTPS Load Balancers are global external load balancers that can distribute traffic to backends across multiple regions, and they support cross-VPC connectivity via Shared VPC or VPC Network Peering, allowing instances in different VPC networks to serve as backends.

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

Common exam traps

Common exam trap: answer the scenario, not the keyword

The trap here is that candidates often confuse the global HTTPS Load Balancer (for external traffic) with the Internal HTTP(S) Load Balancer (for internal traffic), leading them to incorrectly select option D as true.

Detailed technical explanation

How to think about this question

The Google Cloud HTTPS Load Balancer is a global proxy-based Layer 7 load balancer that terminates TLS connections at the edge of Google's network, using a single anycast IP address (as stated in option E) to route traffic to the closest healthy backend. It leverages Google's global infrastructure and supports cross-regional failover, but for internal traffic within a VPC, the Internal HTTP(S) Load Balancer (Envoy-based) is used, which operates within a single region and VPC network.

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.
