Objective 1.3
PCADesigning network, storage, and compute resources
Objective 1.3 sits in Designing and planning a cloud solution architecture, which carries 25% of the Cloud Architect exam. The questions below are original, written from the official objective title above, and each explanation cites the Google Cloud page it rests on.

A worked example
Shown solved, with the whole explanation open: this is what every question here carries.
An application carries UDP and ESP traffic and the team needs backend VMs to see the original client source addresses. Which load balancer family fits that traffic?
Correct.
Concept
Protocol support and address preservation move together: anything that terminates a connection has to speak the protocol it terminates, so non-TCP traffic narrows the field before any feature comparison starts.
Why C
Passthrough Network Load Balancers handle TCP and UDP and also support other IP protocols such as ESP, GRE, ICMP and ICMPv6, and they preserve client source IP addresses.

Now you: objective 1.3 questions
No account needed. The explanation opens when you answer.
Sample question 1 of 3
A team captures traffic and finds that responses from the backend VMs travel straight to the clients rather than back through the load balancer. Which property of their load balancer accounts for that?
Sample question 2 of 3
A regulator requires an organization to terminate TLS only inside one named jurisdiction. Which load balancer choice meets that?
Sample question 3 of 3
An internal service needs backends in two regions, reachable only from clients inside the VPC network. Which load balancer scope does that call for?

Read the sources
These are the official pages the questions above cite. Reading them is studying the objective from the primary source, which is what the explanations point you toward anyway.
