VPN
Why wrong: VPN is not a VLAN attachment type; it is a separate service.
- C
PARTNER
PARTNER is correct for Layer 3 connectivity where the partner provides IP addresses and routing.

PCNE Implementing Hybrid Interconnectivity Practice Question
This PCNE practice question tests your understanding of implementing hybrid interconnectivity. 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.
Your company has a Partner Interconnect connection via a service provider that offers Layer 3 connectivity. The provider assigns an IP address on the VLAN attachment. Which VLAN attachment type should you use when creating the attachment in Google Cloud?

Correct answer & explanation
✓
PARTNER
When a service provider offers Layer 3 connectivity and assigns an IP address on the VLAN attachment, you must use the PARTNER attachment type. This type is specifically designed for Partner Interconnect with Layer 3 (routed) connections, where the provider manages the IP addressing and routing. PARTNER_PROVIDER is used for Layer 2 attachments where you assign your own IP addresses.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
Cisco often tests the distinction between Layer 2 and Layer 3 attachments in Partner Interconnect, trapping candidates who confuse PARTNER_PROVIDER (Layer 2, customer-assigned IPs) with PARTNER (Layer 3, provider-assigned IPs).
Detailed technical explanation
How to think about this question
In Google Cloud, Partner Interconnect supports two attachment types: PARTNER (Layer 3) and PARTNER_PROVIDER (Layer 2). With PARTNER attachments, the service provider assigns the IP addresses and handles BGP sessions, simplifying configuration for the customer. This is analogous to a MPLS L3VPN service where the provider manages the CE-PE routing. The PARTNER attachment type uses VLAN attachments with a single VLAN ID, and the provider's edge router establishes BGP peering with your Cloud Router.
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 cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
