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.
A team wants to deploy a microservice on Cloud Run that needs to access a Cloud Memorystore for Redis instance in the same region. The Redis instance is in a VPC network. Which configuration is required for Cloud Run to reach the Redis instance?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Create a Serverless VPC Access connector and configure Cloud Run to use it
Cloud Run services can connect to a VPC using a Serverless VPC Access connector, which provides private network access.
Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Configure a Cloud NAT gateway
Why it's wrong here
Cloud NAT provides outbound internet access, not private access to VPC resources.
✓
Create a Serverless VPC Access connector and configure Cloud Run to use it
Why this is correct
The connector enables Cloud Run to send traffic to the VPC.
Related concept
Static NAT maps one inside address to one outside address.
✗
Use Private Google Access
Why it's wrong here
Private Google Access allows access to Google APIs without public IP, not to Memorystore.
✗
Deploy Cloud Run within a VPC
Why it's wrong here
Cloud Run is a serverless platform that cannot be deployed inside a VPC.
Common exam traps
Common exam trap: NAT rules depend on direction and matching traffic
NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.
Detailed technical explanation
How to think about this question
NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.
KKey Concepts to Remember
Static NAT maps one inside address to one outside address.
PAT allows many inside hosts to share one public address using ports.
Inside local and inside global describe the private and translated addresses.
NAT ACLs identify traffic for translation, not always security filtering.
TExam Day Tips
→Identify inside and outside interfaces first.
→Check whether the scenario needs static NAT, dynamic NAT or PAT.
→Do not confuse NAT matching ACLs with normal packet-filtering intent.
Key takeaway
NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
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.
