- A
The facility must offer Layer 2 connectivity to the Google Cloud VPC.
Why wrong: Dedicated Interconnect provides Layer 2 connectivity, but the facility selection is based on access to a Google PoP.
- B
The facility must be a Google Cloud partner facility with access to a Google PoP in the same metro as the on-premises data center.
This ensures low latency and meets the requirements for Dedicated Interconnect.
- C
The facility must support 100 Gbps ports to maximize throughput.
Why wrong: Port speed is a consideration but not the most critical factor for facility selection.
- D
The facility must be in a different continent to ensure geographic redundancy.
Why wrong: Geographic redundancy is important but the primary factor is proximity to the on-premises location to minimize latency.
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.
An organization wants to connect their on-premises network to Google Cloud using a Dedicated Interconnect. They have ordered a circuit from a network service provider and need to determine the correct co-location facility to connect to. Which factor is most critical when selecting a co-location facility?
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
The facility must be a Google Cloud partner facility with access to a Google PoP in the same metro as the on-premises data center.
The co-location facility must be a Google Cloud partner facility that provides access to a Google Point of Presence (PoP) in the same metro area as the organization's on-premises data center to minimize latency and meet SLA requirements.
Key principle: OSPF neighbour adjacency depends on matching area, hello/dead timers, network type, and authentication — IP reachability alone is not enough.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
The facility must offer Layer 2 connectivity to the Google Cloud VPC.
Why it's wrong here
Dedicated Interconnect provides Layer 2 connectivity, but the facility selection is based on access to a Google PoP.
- ✓
The facility must be a Google Cloud partner facility with access to a Google PoP in the same metro as the on-premises data center.
Why this is correct
This ensures low latency and meets the requirements for Dedicated Interconnect.
Related concept
OSPF neighbours must agree on key parameters.
- ✗
The facility must support 100 Gbps ports to maximize throughput.
Why it's wrong here
Port speed is a consideration but not the most critical factor for facility selection.
- ✗
The facility must be in a different continent to ensure geographic redundancy.
Why it's wrong here
Geographic redundancy is important but the primary factor is proximity to the on-premises location to minimize latency.
Common exam traps
Common exam trap: OSPF can fail even when IP connectivity looks correct
OSPF neighbour formation depends on matching areas, timers, network type, authentication and passive-interface behaviour. Do not choose an answer only because the devices can ping.
Detailed technical explanation
How to think about this question
OSPF questions usually test the details that control adjacency and route selection. Read the neighbour state, area, router ID and interface configuration before deciding what is wrong.
KKey Concepts to Remember
- OSPF neighbours must agree on key parameters.
- Router ID selection can affect neighbour relationships and LSDB output.
- OSPF cost influences the preferred path.
- A route can appear in OSPF information but not become the installed route.
TExam Day Tips
- Check area mismatch first when OSPF adjacency fails.
- Review passive interfaces when a network is advertised but no neighbour forms.
- Use show ip ospf neighbor and show ip route clues carefully.
Key takeaway
OSPF neighbour adjacency depends on matching area, hello/dead timers, network type, and authentication — IP reachability alone is not enough.
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 OSPF neighbour requirements — matching area type, hello and dead timers, network type, stub flags, and authentication. Study show ip ospf neighbor states (INIT, 2-WAY, FULL). Then practise related PCNE OSPF questions on adjacency and route selection.
