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
✓
Two 10Gbps Dedicated Interconnect connections, each with its own VLAN attachment and BGP session, from the same provider
Dedicated Interconnect offers 99.99% SLA when you have two separate physical connections (each 10Gbps or 100Gbps) from the same provider, each with its own VLAN attachment and BGP session, and they are configured in a redundant manner.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
A single 10Gbps Dedicated Interconnect connection with one VLAN attachment and one BGP session
Why it's wrong here
A single connection does not meet 99.99% SLA; redundancy is required.
- ✗
A single 100Gbps Dedicated Interconnect connection with two VLAN attachments and two BGP sessions
Why it's wrong here
A single physical connection, even with multiple VLANs, does not provide redundancy for the physical link.
- ✓
Two 10Gbps Dedicated Interconnect connections, each with its own VLAN attachment and BGP session, from the same provider
Why this is correct
Two redundant connections are required for 99.99% SLA.
- ✗
Two Partner Interconnect connections with 99.9% SLA each
Why it's wrong here
Partner Interconnect maximum SLA is 99.9% without multiple connections, and 99.99% requires two connections, but the scenario specifies Dedicated Interconnect.
