- A
Two Partner Interconnect connections from different providers in the same metro area
Why wrong: Partner Interconnect has a different SLA; Dedicated Interconnect SLA specifically requires two connections in different metro areas.
- B
Two Dedicated Interconnect connections in the same metro area with active-passive configuration
Why wrong: SLA requires connections in different metro areas for 99.99%.
- C
Single Dedicated Interconnect connection with two VLAN attachments
Why wrong: A single connection does not meet the 99.99% SLA; at least two connections are needed.
- D
Two Dedicated Interconnect connections in different metro areas with active-active configuration
Two connections in different metro areas provide geographic redundancy and meet the 99.99% SLA.

PCNE Implementing Hybrid Interconnectivity Practice Question
This PCNE practice question tests your understanding of implementing hybrid interconnectivity. 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.
An enterprise requires a hybrid connectivity solution that meets a 99.99% SLA. They plan to use Dedicated Interconnect. Which configuration satisfies the SLA requirement?

Correct answer & explanation
✓
Two Dedicated Interconnect connections in different metro areas with active-active configuration
Google's 99.99% SLA for Dedicated Interconnect requires two connections, each from a different metro area, configured for active-active or active-passive.
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.
- ✗
Two Partner Interconnect connections from different providers in the same metro area
Why it's wrong here
Partner Interconnect has a different SLA; Dedicated Interconnect SLA specifically requires two connections in different metro areas.
- ✗
Two Dedicated Interconnect connections in the same metro area with active-passive configuration
Why it's wrong here
SLA requires connections in different metro areas for 99.99%.
- ✗
Single Dedicated Interconnect connection with two VLAN attachments
Why it's wrong here
A single connection does not meet the 99.99% SLA; at least two connections are needed.
- ✓
Two Dedicated Interconnect connections in different metro areas with active-active configuration
Why this is correct
Two connections in different metro areas provide geographic redundancy and meet the 99.99% SLA.
Related concept
OSPF neighbours must agree on key parameters.
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 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. OSPF neighbour adjacency depends on matching area, hello/dead timers, network type, and authentication — IP reachability alone is not enough. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
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.
