Google PCA Practice Question: Managing and Provisioning a Solution Infrastructure
This PCA practice question tests your understanding of managing and provisioning a solution infrastructure. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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.
An organization wants to manage DNS records for a domain they own (e.g., example.com) and use Google Cloud for authoritative DNS. They also need to resolve internal hostnames for resources within their VPC. Which Cloud DNS configuration should they use?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Create a public managed zone for example.com and a private managed zone for internal VPC resources
Cloud DNS public zones manage public DNS records for internet-facing domains. Cloud DNS private zones are used for internal DNS resolution within VPCs. The correct approach is to create a public zone for example.com and a private zone for internal hostnames attached to the VPC.
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.
✗
Create a single public managed zone and use DNS peering for internal resolution
Why it's wrong here
DNS peering forwards queries between zones, but a public zone alone cannot resolve internal hostnames within a VPC.
✗
Create a single private managed zone for both external and internal DNS resolution
Why it's wrong here
A private zone is only accessible within the VPC; external queries would not be answered.
✗
Use Google Groups DNS to manage both public and private records
Why it's wrong here
There is no such service as Google Groups DNS. Cloud DNS is the only DNS service.
✓
Create a public managed zone for example.com and a private managed zone for internal VPC resources
Why this is correct
Public zone handles external DNS queries; private zone attached to the VPC handles internal resolution.

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.
