Google PCA Manage and provision cloud infrastructure Practice Question

This PCA practice question tests your understanding of manage and provision cloud infrastructure. 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.

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

✓

VPC-native networking

A is correct because VPC-native networking is the default and recommended networking mode for GKE clusters, where the cluster uses alias IP ranges (RFC 6598) on the VPC network. This mode assigns pod IP addresses directly from the VPC subnet's secondary IP range, enabling native integration with VPC features like Cloud NAT, VPC Flow Logs, and firewall rules without requiring manual route management.

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.

  • ✓

    VPC-native networking

    Why this is correct

    Correct. IP aliases and secondary ranges indicate VPC-native mode.

    Related concept

    Read the scenario before looking for a memorised answer.

  • ✗

    Hybrid networking

    Why it's wrong here

    Hybrid refers to on-prem to cloud connections.

  • ✗

    Standard networking

    Why it's wrong here

    Standard is often synonymous with routes-based.

  • ✗

    Routes-based networking

    Why it's wrong here

    Routes-based clusters do not use IP aliases.

  • ✗

    Private cluster networking

    Why it's wrong here

    privateCluster is false, so it's not private.

Common exam traps

Common exam trap: answer the scenario, not the keyword

The trap here is that candidates confuse 'private cluster' (a cluster with internal-only node IPs) with a networking mode, when in fact private clusters can use either VPC-native or routes-based networking, and the question specifically asks for the networking mode.

Detailed technical explanation

How to think about this question

Under the hood, VPC-native clusters use Kubernetes Engine's network endpoint group (NEG) integration with Cloud Load Balancing, enabling direct pod routing via the VPC's secondary IP range (e.g., 10.0.0.0/16 for pods) and avoiding the need for manual route creation. A subtle behavior is that VPC-native clusters require the VPC subnet to have at least one secondary IP range configured for pods and one for services; if these are missing, cluster creation fails. In a real-world scenario, using VPC-native networking simplifies compliance with VPC Service Controls and allows pod IPs to be directly firewalled using VPC firewall rules, which is critical for security-sensitive workloads.

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.
