- A
Cloud Load Balancing: Distributes incoming traffic across multiple instances
Cloud Load Balancing is correctly defined as distributing incoming traffic across multiple instances.
- B
Cloud CDN: Caches content at edge locations for low latency delivery
Cloud CDN is correctly defined as caching content at edge locations for low latency delivery.
- C
Cloud DNS: Translates domain names to IP addresses
Cloud DNS is correctly defined as translating domain names to IP addresses.
- D
Cloud NAT: Caches content at edge locations
Why wrong: Incorrect — caching content at edge locations describes Cloud CDN, not Cloud NAT.
- E
Virtual Private Cloud: Provides dedicated connection between on-premises and VPC
Why wrong: Incorrect — providing dedicated connection between on-premises and VPC describes Cloud Interconnect, not Virtual Private Cloud.
- F
Cloud Interconnect: Translates domain names to IP addresses
Why wrong: Incorrect — translating domain names to IP addresses describes Cloud DNS, not Cloud Interconnect.
Match Google Cloud Networking Services to Their Functions
This PCNE practice question tests your understanding of pcne exam topics. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. 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.
Match each Google Cloud networking service to its primary function.

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
Cloud Load Balancing: Distributes incoming traffic across multiple instances
Correct matches: Cloud Load Balancing distributes traffic, Cloud CDN caches content, Cloud DNS resolves domain names. Common confusions: Cloud NAT is for internet access without external IPs, Virtual Private Cloud provides isolated networks, and Cloud Interconnect connects on-premises to Google Cloud.
Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.

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.

What to study next
Got this wrong? Here's your next step.
Review the four NAT address types (inside local, inside global, outside local, outside global), PAT port overload, and static vs dynamic NAT use cases. Then practise related PCNE NAT questions on configuration and troubleshooting.
